ture.

When frequent transmission shifting occurs while using Overdrive, such as when operating the vehicle under heavy load conditions (for example, in hilly terrain, strong head winds, or trailer towing), turning off over- drive will improve performance and extend transmission life by reducing excessive shifting and heat buildup.

STARTING AND OPERATING 223

O/D Off Button

Overdrive can be locked out by pressing the O/D OFF button located on side of the gearshift lever. The O/D OFF indicator light will illuminate to show that the switch has been activated. When the indicator light is on, Overdrive is locked out. Pressing the switch a second

224 STARTING AND OPERATING

time restores the Overdrive function. The lockout feature is useful when towing a trailer or carrying a heavy load. If the vehicle is started in cold outside tempera- NOTE: tures, shifts into Overdrive may be delayed. Normal Overdrive and shifting operation will resume when the temperature of the transmission reaches the appropriate temperature. Refer to the “Note” under “Torque Con- verter Clutch” later in this section. If the transmission temperature gets too hot, the trans- mission may downshift out of Overdrive or engage overdrive at higher vehicle speeds until the transmission cools down. After cooldown, Overdrive will resume normal operation. 2 (Second) For moderate grades and to assist braking on dry pave- ment or in mud and snow. Begins at a stop in low gear with automatic upshift to 2nd gear. Will not shift to 3rd.

1 (First) For hard pulling at low speeds in mud, sand, snow, or on steep grades. Begins and stays in low gear with no upshift. Provides engine compression braking at low speeds.

CAUTION!

• Never press on the accelerator pedal with the en- gine running, vehicle in gear, and the brakes ap- plied. Always apply the brakes when stopped on a incline. Failure to follow these instructions can cause overheating and damage to the transmission. • When “rocking” a stuck vehicle by moving be- tween “First” and R (Reverse), do not spin the wheels faster than 15 mph (24 km/h), or drivetrain damage may result.

the condition. This may result

Over Temperature Mode The transmission electronics constantly monitor the transmission oil temperature. If the transmission gets too hot, the transmission will change the way it shifts to help control in a slightly different feeling or response during normal operation in D (Drive) position. If the transmission becomes hot enough the TRANS TEMP warning light in the instru- ment cluster will come on. After the transmission cools down, it will return to normal operation. Torque Converter Clutch A feature designed to improve fuel economy has been added to the automatic transmission of this vehicle. A clutch within the torque converter engages automatically at calibrated speeds. This may result in a slightly differ- ent feeling or response during normal operation in high gear. When the vehicle speed drops or during accelera- tion, the clutch automatically and smoothly disengages.

STARTING AND OPERATING 225

NOTE: • The torque converter clutch (TCC) will not engage until the transmission fluid and engine coolant are warm (usually after 1–3 miles (1.6–4.8 km) of driving) and the vehicle speed is above approximately 30 mph (48 km/h). To understand the difference in operation, drive the vehicle so that TCC engagement conditions are correct, and then press and release the “O/D OFF” button once to disengage the TCC. Wait a few seconds, and then press and release the “O/D OFF” button again to engage the TCC. You will notice that the engine runs at a higher RPM when driving at vehicle speeds above approximately 30 mph (48 km/h) with the TCC not engaged. This is a normal condition. • If the vehicle has not been driven for several days, the first few seconds of operation after shifting the trans- mission into gear may seem sluggish. This is due to the transmission fluid partially draining from the torque converter into the transmission. This is considered a

226 STARTING AND OPERATING

normal condition and will not cause damage to the transmission. The torque converter will refill within 5
seconds of shifting from P (Park) into any other gear position.

FOUR-WHEEL DRIVE OPERATION

Command-Trac姞 Operating Information/Precautions The Command-Trac威 transfer case provides 4 mode positions - 2 (rear) wheel drive high range, 4-wheel drive high range, neutral, and 4-wheel drive low range. This transfer case is intended to be driven in the 2-wheel drive position (2H) for normal street and highway con- ditions such as dry hard surfaced roads. When additional traction is required the transfer case 4H and 4L positions can be used to lock the front and rear driveshafts together and force the front and rear wheels to rotate at the same speed. This is accomplished by

simply moving the shift lever to these positions. The 4H and 4L positions are intended for loose, slippery road surfaces only. Driving in the 4H and 4L positions on dry hard surfaced roads may cause increased tire wear and damage to the driveline components. The PART TIME indicator light, located in the instrument cluster, illuminates when the transfer case is shifted to the 4H position. The 4 LO MODE indicator light, located in the instru- ment cluster, illuminates when the transfer case is shifted to the 4L position. There is no light for the 2H or N (Neutral) positions.

CAUTION!

• Do not attempt to make a shift while only the front or rear wheels are spinning. The Command- Trac transfer case is not equipped with a synchro- nizer and therefore the front and rear driveshaft speeds must be equal for the shift to take place. Shifting while only the front or rear wheels are spinning can cause damage to the transfer case. • When operating your vehicle in 4L, the engine speed is approximately three times that of the 2H or 4H positions at a given road speed. Take care not to overspeed the engine and do not exceed 25
mph (40 km/h).

Proper operation of 4-wheel drive vehicles depends on tires of equal size, type and circumference on each wheel. Any difference will adversely affect shifting and can cause damage to the transfer case.

STARTING AND OPERATING 227

WARNING!

• Because 4-wheel drive provides improved trac- tion, there is a tendency to exceed safe turning and stopping speeds. Do not go faster than road con- ditions permit. • You or others could be injured if you leave the vehicle unattended with the transfer case in the Neutral (N) position without first fully engaging the parking brake. The transfer case Neutral (N) position disengages both the front and rear drive- shafts from the powertrain and will allow the vehicle to move despite the transmission position. The parking brake should always be applied when the driver is not in the vehicle.

228 STARTING AND OPERATING

Shift Positions For additional information on the appropriate use of each transfer case mode position see the information below: 2H Rear Wheel Drive High Range - Normal street and highway driving. Dry hard surfaced roads. 4H 4-Wheel-Drive High Range - Locks the front and rear driveshafts together. Forces the front and rear wheels to rotate at the same speed. Additional traction for loose, slippery road surfaces only. Neutral - Disengages both the front and rear driveshafts from the powertrain. To be used for flat towing behind another vehicle. Refer to “Recreational Towing” in Sec- tion 5 for more information.

4L 4-Wheel-Drive Low Range - Low speed 4 wheel drive. Locks the front and rear driveshafts together. Forces the front and rear wheels to rotate at the same speed. Additional traction and maximum pulling power for loose, slippery road surfaces only. Do not exceed 25 mph (40 km/h). (Allows engine starting without depressing the clutch pedal on vehicles equipped with manual transmission. Refer to “Starting Procedures — Manual Transmission (4WD Models Only)” in this section. Shifting Procedure

2H to 4H or 4H to 2H Shifting between 2H and 4H can be made with the vehicle in motion up to 55 mph (88 km/h). The transfer case will engage/disengage faster if you momentarily release the accelerator pedal after completing the shift. Apply a constant force when shifting the transfer case lever.

4H to 4L or 4L to 4H With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift an automatic transmission to N (Neutral) or depress the clutch on a manual transmission. While the vehicle is coasting at 2 to 3 mph (3 to 5 km/h), shift the transfer case lever firmly to the desired position. Do not pause in transfer case N (Neutral). NOTE: To shift from 4H to 4L, the shift lever should pushed away from the driver, and then rearward into 4L. In 4H, there is a neutral stop to prevent shifting into N (Neutral) by accident. NOTE: Pausing in transfer case N (Neutral) in vehicles equipped with an automatic transmission may require shutting the engine OFF to avoid gear clash while completing the shift. If difficulty occurs, shift automatic transmission to N (Neutral), hold foot on brake, and turn engine OFF. Make shift to the desired mode.

STARTING AND OPERATING 229

NOTE: Shifting into or out of 4L is possible with the vehicle completely stopped, however difficulty may oc- cur due to the mating clutch teeth not being properly aligned. Several attempts may be required for clutch teeth alignment and shift completion to occur. The pre- ferred method is with the vehicle rolling 2 to 3 mph (3 to 5 km/h). Avoid attempting to engage or disengage 4L with the vehicle moving faster than 2 to 3 mph (3 to 5
km/h). Selec-Trac姞 Operating Information/Precautions — If Equipped The Selec-Trac威 transfer case provides 5 mode positions - normal 2-wheel drive mode, part-time 4-wheel drive high range, full-time 4-wheel drive high range, neutral, and 4-wheel drive low range. This transfer case is equipped with an inter-axle differ- ential which allows driving the vehicle in the 4 FULL TIME position at all times on any given road surface

230 STARTING AND OPERATING

including dry hard surfaced roads. The 4 FULL TIME mode allows the front and rear wheels to rotate at different speeds which eliminates driveline binding and component wear that is normally associated with driving the vehicle in the 4 PART TIME position on dry hard surfaced roads. This feature provides the safety, security, and convenience of operating in 4–wheel drive at all times regardless of road conditions. When additional traction is required the 4 PART TIME and 4LO positions can be used to lock the front and rear driveshafts together through the transfer case inter-axle differential and force the front and rear driveshafts to rotate at the same speed. This is accomplished by simply moving the shift lever to these positions. The 4 PART TIME and 4LO positions are intended for loose, slippery road surfaces only. Driving in the 4 PART TIME and 4LO positions on dry hard surfaced roads may cause in- creased tire wear and damage to driveline components.

The PART TIME indicator light, located on the instru- ment cluster, illuminates when the transfer case is shifted to the 4 PART TIME position. The FULL TIME indicator light, located on the instru- ment cluster, illuminates when the transfer case is shifted to the 4 FULL TIME position. The 4LO MODE indicator light, located on the instru- ment cluster, illuminates when the transfer case is shifted to the 4LO position. There is no light for the 2WD, or N (Neutral) positions.

CAUTION!

• Do not attempt to make a shift while only the front or rear wheels are spinning. The Selec-Trac transfer case is not equipped with a synchronizer and therefore the front and rear driveshaft speeds must be equal for the shift to take place. Shifting while only the front or rear wheels are spinning can cause damage to the transfer case. • When operating your vehicle in 4LO, the engine speed is approximately three times that of the 2WD, 4 PART TIME, or 4 FULL TIME positions at a given road speed. Take care not to overspeed the engine and do not exceed 25 mph (40 km/h).

Proper operation of 4-wheel drive vehicles depends on tires of equal size, type, and circumference on each wheel. Any difference will adversely affect shifting and can cause damage to the transfer case.

WARNING!

• Because 4-wheel drive provides improved trac- tion, there is a tendency to exceed safe turning and stopping speeds. Do not go faster than road con- ditions permit. • You or others could be injured if you leave the vehicle unattended with the transfer case in the Neutral (N) position without first fully engaging the parking brake. The transfer case Neutral (N) position disengages both the front and rear drive- shafts from the powertrain and will allow the vehicle to move regardless of the transmission position. The parking brake should always be applied when the driver is not in the vehicle.

2WD to 4 PART TIME or 4 PART TIME to 2WD Shifting between 2WD and 4 PART TIME can be made with the vehicle stopped or in motion. If the vehicle is in motion, shifts can be made up to 55 mph (88 km/h). With the vehicle in motion two momentary releases of the

accelerator pedal may be required after shifting. This will induce a torque interrupt and allow full engagement of the newly selected position. With the vehicle stationary it may be necessary to shift the automatic transmission from D (Drive) to R (Reverse) and back to D (Drive) after shifting. This will allow full engagement of the newly selected position. Apply a constant force when shifting the transfer case lever. 4 PART TIME to 4 FULL TIME or 4 FULL TIME to 4 PART TIME Shifting between 4 PART TIME and 4 FULL TIME can be made with the vehicle stopped or in motion. If the vehicle is in motion shifts can be made up to 55 mph (88 km/h). With the vehicle in motion two momentary releases of the accelerator pedal may be required after shifting.

shifting. This will allow full engagement of the newly selected position. Apply a constant force when shifting the transfer case lever. 4 FULL TIME to 4 LO or 4 LO to 4 FULL TIME With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift an automatic transmission to N (Neutral). While the vehicle is coasting at 2 to 3 mph (3 to 5 km/h), shift the transfer case lever firmly to the desired position. Do not pause in transfer case N (Neutral). NOTE: To shift from 4 FULL TIME to 4LO, the shift lever should be pushed away from the driver, and then rearward into 4LO. In 4 FULL TIME, there is a neutral stop to prevent shifting into N (Neutral) by accident. NOTE: Pausing in transfer case N (Neutral) in vehicles equipped with an automatic transmission may require shutting the engine OFF to avoid gear clash while

234 STARTING AND OPERATING

completing the shift. If difficulty occurs, shift transmis- sion to N (Neutral), hold foot on brake, and turn engine OFF. Make shift to desired mode. NOTE: Shifting into or out of 4LO is possible with the vehicle completely stopped, however difficulty may oc- cur due to the mating clutch teeth not being properly aligned. Several attempts may be required for clutch teeth alignment and shift completion to occur. The pre- ferred method is with the vehicle rolling 2 to 3 mph (3 to 5 km/h). Avoid attempting to engage or disengage 4LO with the vehicle moving faster than 2 to 3 mph (3 to 5
km/h).

TRAC-LOK™ REAR AXLE — IF EQUIPPED The optional Trac-Lok™ rear axle provides a constant driving force to both rear wheels and reduces wheel spin caused by the loss of traction at one driving wheel. If traction differs between the two rear wheels, the differ- ential automatically proportions the usable torque by providing more torque to the wheel that has traction. Trac-Lok™ is especially helpful during slippery driving conditions. With both rear wheels on a slippery surface, a slight application of the accelerator will supply maxi- mum traction. When starting with only one rear wheel on an excessively slippery surface, slight application of the parking brake may be necessary to gain maximum trac- tion.

WARNING!

On vehicles equipped with a limited-slip differen- tial, never run the engine with one rear wheel off the ground. The vehicle may drive through the rear wheel remaining on the ground and cause you to lose control of your vehicle.

ON-ROAD DRIVING TIPS Utility vehicles have higher ground clearance and a narrower track to make them capable of performing in a wide variety of off-road applications. Specific design characteristics give them a higher center of gravity than ordinary cars. An advantage of the higher ground clearance is a better view of the road, allowing you to anticipate problems. They are not designed for cornering at the same speeds as

STARTING AND OPERATING 235

conventional 2-wheel drive vehicles any more than low- slung sports cars are designed to perform satisfactorily in off-road conditions. If at all possible, avoid sharp turns or abrupt maneuvers. As with other vehicles of this type, failure to operate this vehicle correctly may result in loss of control or vehicle rollover.

OFF-ROAD DRIVING TIPS

When To Use 4L or 4LO (Low) Range When off-road driving, shift to 4L or 4LO for additional traction and control on slippery or difficult terrain, ascending or descending steep hills, and to increase low-speed pulling power. This range should be limited to extreme situations such as deep snow, mud, or sand where additional low speed pulling power is needed. Vehicle speeds in excess of 25 mph (40 km/h) should be avoided when in 4L or 4LO range.

236 STARTING AND OPERATING

Driving Through Water Although your vehicle is capable of driving through water, there are a number of precautions that must be considered before entering the water:

CAUTION!

When driving through water, do not exceed 5 mph (8
km/h). Always check water depth before entering as a precaution, and check all fluids afterward. Driving through water may cause damage that may not be covered by the new vehicle limited warranty.

Driving through water more than a few inches deep will require extra caution to ensure safety and prevent dam- age to your vehicle. If you must drive through water, try to determine the depth and the bottom condition (and location of any obstacles) prior to entering. Proceed with

caution and maintain a steady controlled speed less than 5 mph (8 km/h) in deep water to minimize wave effects. Flowing Water If the water is swift flowing and rising (as in storm run-off) avoid crossing until the water level recedes and/or the flow rate is reduced. If you must cross flowing water avoid depths in excess of 9 inches. The flowing water can erode the streambed causing your vehicle to sink into deeper water. Determine exit point(s) that are downstream of your entry point to allow for drifting. Standing Water Avoid driving in standing water deeper than 20 inches, and reduce speed appropriately to minimize wave ef- fects. Maximum speed in 20 inches of water is less than 5
mph (8 km/h).

Maintenance After driving through deep water, inspect your vehicle fluids and lubricants (engine oil, transmission oil, axle, transfer case) to assure the fluids have not been contami- nated. Contaminated fluid (milky, foamy in appearance) should be flushed/changed as soon as possible to pre- vent component damage. Driving In Snow, Mud and Sand In heavy snow, when pulling a load, or for additional control at slower speeds, shift the transmission to a low gear and shift the transfer case to 4L or 4LO if necessary. Refer to “Four-Wheel Drive Operation” in this section. Do not shift to a lower gear than necessary to maintain headway. Over-revving the engine can spin the wheels and traction will be lost. Avoid abrupt downshifts on icy or slippery roads, be- cause engine braking may cause skidding and loss of control.

STARTING AND OPERATING 237

Hill Climbing

NOTE: Before attempting to climb a hill, determine the conditions at the crest and/or on the other side. Before climbing a steep hill, shift the transmission to a lower gear and shift the transfer case to 4L or 4LO. Use first gear and 4L or 4LO for very steep hills. If you stall or begin to lose headway while climbing a steep hill, allow your vehicle to come to a stop and immediately apply the brakes. Restart the engine and shift to R (Reverse). Back slowly down the hill allowing the compression braking of the engine to help regulate your speed. If the brakes are required to control vehicle speed, apply them lightly and avoid locking or skidding the tires.

238 STARTING AND OPERATING

WARNING!

If the engine stalls or you lose headway or cannot make it to the top of a steep hill or grade, never attempt to turn around. To do so may result in tipping and rolling the vehicle. Always back care- fully straight down a hill in R (Reverse) gear. Never back down a hill in N (Neutral) using only the brake.

Remember, never drive diagonally across a hill-always drive straight up or down. If the wheels start to slip as you approach the crest of a hill, ease off the accelerator and maintain headway by turning the front wheels slowly left and right. This may provide a fresh “bite” into the surface and will usually provide traction to complete the climb.

Traction Downhill Shift the transmission into a low gear and the transfer case to 4L or 4LO range. Let the vehicle go slowly down the hill with all four wheels turning against engine compression drag. This will permit you to control the vehicle speed and direction. When descending mountains or hills, repeated braking can cause brake fade with loss of braking control. Avoid repeated heavy braking by downshifting the transmis- sion whenever possible. After Driving Off-Road Off-road operation puts more stress on your vehicle than does most on-road driving. After going off-road it is always a good idea to check for damage. That way you can get any problems taken care of right away and have your vehicle ready when you need it.

• Completely inspect the underbody of your vehicle. Check tires, body structure, steering, suspension, and exhaust system for damage. • Check threaded fasteners for looseness, particularly on the chassis, drivetrain components, steering, and sus- pension. Retighten them, if required, and torque to the values specified in the Service Manual. • Check for accumulations of plants or brush. These things could be a fire hazard. They might hide damage lines, brake hoses, axle pinion seals, and to fuel propeller shafts. • After extended operation in mud, sand, water, or similar dirty conditions, have brake rotors, wheels, brake linings, and axle yokes inspected and cleaned as soon as possible.

STARTING AND OPERATING 239

WARNING!

Abrasive material in any part of the brakes may cause excessive wear or unpredictable braking. You might not have full braking power when you need it to prevent an accident. If you have been operating your vehicle in dirty conditions, get your brakes checked and cleaned as necessary. • If you experience unusual vibration after driving in mud, slush or similar conditions, check the wheels for impacted material. Impacted material can cause a wheel imbalance and freeing the wheels of it will correct the situation.

240 STARTING AND OPERATING

PARKING BRAKE To set the parking brake, pull the lever up as firmly as possible. When the parking brake is applied with the ignition ON, the “Brake Warning Light” in the instru- ment cluster will light. To release the parking brake, pull up slightly, press the center button, then lower the lever completely. NOTE: The instrument cluster “Brake Warning Light” indicates only that the parking brake is applied. You must be sure the parking brake is fully applied before leaving the vehicle.

Parking Brake

Be sure the parking brake is firmly set when parked, and the gear shift lever is in the P (Park) position (automatic transmission) or R (Reverse) or 1st gear (manual transmis- sion). When parking on a hill, you should apply the parking brake before placing the gear shift lever in P (Park), other- wise the load on the transmission locking mechanism may make it difficult to move the selector out of P (Park).

WARNING!

• Always fully apply the parking brake when leaving your vehicle, or it may roll and cause damage or injury. Also, be certain to leave an automatic trans- mission in P (Park), a manual transmission in R (Reverse) or 1st gear. Failure to do so may allow the vehicle to roll and cause damage or injury. • Leaving children in a vehicle unattended is danger- ous for a number of reasons. A child or others could be injured. Children should be warned not to touch the parking brake or the gear selector lever. Don’t leave the keys in the ignition. A child could operate power windows, other controls, or move the vehicle. • Be sure the parking brake is fully disengaged before driving, failure to do so can lead to brake problems due to excessive heating of the rear brakes.

STARTING AND OPERATING 241

When parking on a hill, turn the front wheels toward the curb on a downhill grade and away from the curb on an uphill grade. The parking brake should always be applied whenever the driver is not in the vehicle.

ANTI-LOCK BRAKE SYSTEM — IF EQUIPPED The Anti-Lock Brake System is designed to aid the driver in maintaining vehicle control under adverse braking conditions. The system operates with a separate com- puter to modulate hydraulic pressure to prevent wheel lock-up and help avoid skidding on slippery surfaces. All vehicle wheels and tires must be the same size and type and tires must be properly inflated to produce accurate signals for the computer.

242 STARTING AND OPERATING

WARNING!

Significant over or under-inflation of tires, or mixing sizes of tires or wheels on the vehicle can lead to loss of braking effectiveness.

The Anti-Lock Brake System conducts a low speed self- test at about 12 mph (20 km/h). If for any reason, your foot is on the brake when the vehicle reaches 12 mph (20 km/h), this check will be delayed until 25 mph (40 km/h). The Anti-Lock Brake System pump motor runs during the self-test and during an ABS stop to provide the regulated hydraulic pressure. The motor pump makes a low humming noise during operation, this is normal.

During off-road use, loss of traction can temporarily defeat the system and cause the warning light to illumi- nate. Turn the ignition OFF and ON again to restore Anti-Lock Brake System function.

WARNING!

Pumping of the Anti-Lock Brakes will diminish their effectiveness and may lead to an accident. Pumping makes the stopping distance longer. Just press firmly on your brake pedal when you need to slow down or stop.

WARNING!

• Anti-lock system (ABS) cannot prevent the natu- ral laws of physics from acting on the vehicle, nor can it increase braking or steering efficiency be- yond that afforded by the condition of the vehicle brakes and tires or the traction afforded.

• The ABS cannot prevent accidents,

including those resulting from excessive speed in turns, following another vehicle too closely, or hydro- planing. Only a safe, attentive, and skillful driver can prevent accidents. • The capabilities of an ABS equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.

STARTING AND OPERATING 243

CAUTION!

The Anti-Lock Brake System is subject to possible detrimental effects of electronic interference caused by improperly installed aftermarket radios or tele- phones.

NOTE: During severe braking conditions, a pulsing sensation may occur and a clicking noise will be heard. This is normal, the Anti-Lock Brake System is functioning.

indicating that

POWER STEERING The standard power steering system will give you good vehicle response and increased ease of maneuverability in tight spaces. The system will provide mechanical steering capability if power assist is lost.

244 STARTING AND OPERATING

If for some reason the power assist is interrupted, it will still be possible to steer your vehicle. Under these condi- tions, you will observe a substantial increase in steering effort, especially at very low vehicle speeds and during parking maneuvers. Increased noise levels at the end of the steering NOTE: wheel travel are considered normal and do not indicate that there is a problem with the power steering system. Upon initial start-up in cold weather, the power steering pump may make noise for a short amount of time. This is due to the cold, thick fluid in the steering system. This noise should be considered normal, and does not in any way damage the steering system.

WARNING!

Continued operation with reduced power steering assist could pose a safety risk to yourself and others. Service should be obtained as soon as possible.

CAUTION!

Prolonged operation of the steering system at the end of the steering wheel travel will increase the steering fluid temperature and it should be avoided when possible. Damage to the power steering pump may occur.

Tire and Loading Information Placard

Tire and Loading Information

This placard tells you important information about the: 1) number of people that can be carried in the vehicle 2) the total weight your vehicle can carry 3) the tire size designed for your vehicle 4) the cold tire inflation pressures for the front, rear and spare tires.

Loading The vehicle maximum load on the tire must not exceed the load carrying capacity of the tire on your vehicle. You will not exceed the tire’s load carrying capacity if you adhere to the loading conditions, tire size and cold tire inflation pressures specified on the Tire and Loading Information placard and the Vehicle Loading section of this manual. NOTE: Under a maximum loaded vehicle condition, gross axle weight ratings (GAWR’s) for the front and rear axles must not be exceeded. For further information on GAWR’s, vehicle loading and trailer towing, see the Vehicle Loading section of this manual. To determine the maximum loading conditions of your vehicle, locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on the Tire and Loading Information placard. The

combined weight of occupants, cargo/luggage and trailer tongue weight (if applicable) should never exceed the weight referenced here. Steps for Determining Correct Load Limit 1. Locate the statement “The combined weight of occu- pants and cargo should never exceed XXX pounds” on your vehicle’s placard. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle. 3. Subtract the combined weight of the driver and pas- sengers from XXX kilograms or XXX pounds. 4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if “XXX” amount equals 1400 lbs. and there will be five 150 lb. passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lb. (since 5 x 150 = 750, and 1400 – 750 = 650 lb.)

STARTING AND OPERATING 251

5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in step 4. 6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle. NOTE: The following table shows examples on how to calculate total load, cargo/luggage and towing capacities of your vehicle with varying seating configurations and number and size of occupants. This table is for illustra- tion purposes only and may not be accurate for the seating and load carry capacity of your vehicle. NOTE: For the following example the combined weight of occupants and cargo should never exceed 865 lbs. (392 Kg).

WARNING!

1. Safety—

STARTING AND OPERATING 253

Overloading of your tires is dangerous. Overloading can cause tire failure, affect vehicle handling, and increase your stopping distance. Use tires of the recommended load capacity for your vehicle. Never overload them.

TIRES — GENERAL INFORMATION

Tire Pressure Proper tire inflation pressure is essential to the safe and satisfactory operation of your vehicle. Three primary areas are affected by improper tire pressure:

WARNING!

Improperly inflated tires are dangerous and can cause accidents. • Under inflation increases tire flexing and can result in tire failure. • Over inflation reduces a tire’s ability to cushion shock. Objects on the road and chuck holes can cause damage that results in tire failure. • Unequal tire pressures can cause steering problems. You could lose control of your vehicle. • Overinflated or under inflated tires can affect vehicle handling and can fail suddenly, resulting in loss of vehicle control. • Unequal tire pressures from one side of the vehicle to the other can cause the vehicle to drift to the right or left. Always drive with each tire properly inflated.

254 STARTING AND OPERATING

2. Economy— Improper inflation pressures can cause uneven wear patterns to develop across the tire tread. These abnormal wear patterns will reduce tread life resulting in a need for earlier tire replacement. Under inflation also increases tire rolling resistance and results in higher fuel consump- tion. 3. Ride Comfort and Vehicle Stability— Proper tire inflation contributes to a comfortable ride. Over inflation produces a jarring and uncomfortable ride. Both under inflation and over inflation affect the stability of the vehicle and can produce a feeling of sluggish response or over responsiveness in the steering. Unequal tire pressures can cause erratic and unpredict- able steering response. Unequal tire pressure from side to side may cause the vehicle to drift left or right.

Tire Inflation Pressures The proper cold tire inflation pressure is listed on either the face of the driver’s door, or the driver’s side “B” pillar.

Tire Placard Location

The pressure should be checked and adjusted as well as inspecting for signs of tire wear or visible damage at least once a month. Use a good quality pocket-type gauge to

check tire pressure. Do not make a visual judgement when determining proper inflation. Radial tires may look properly inflated even when they are under inflated.

CAUTION!

After inspecting or adjusting the tire pressure al- ways reinstall the valve stem cap–if equipped. This will prevent moisture and dirt from entering the valve stem, which could damage the valve stem.

Inflation pressures specified on the placard are always “cold tire inflation pressure”. Cold tire inflation pressure is defined as the tire pressure after the vehicle has not been driven for at least 3 hours, or driven less than 1 mile (1 km) after a 3 hour period. The cold tire inflation pressure must not exceed the maximum inflation pres- sure molded into the tire side wall.

STARTING AND OPERATING 255

Check tire pressures more often if subject to a wide range of outdoor temperatures, as tire pressures vary with temperature changes. Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air temperature change. Keep this in mind when checking tire pressure inside a garage especially in the winter. Example: If garage temperature = 68° F (20° C) and the outside temperature = 32° F (0° C) then the cold tire inflation pressure should be increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12° F (7° C) for this outside temperature condition. Tire pressure may increase from 2 to 6 psi (13 to 40 kPa) during operation. DO NOT reduce this normal pressure build up or your tire pressure will be too low.

256 STARTING AND OPERATING

Tire Pressures for High Speed Operation The manufacturer advocates driving at safe speeds within posted speed limits. Where speed limits or condi- tions are such that the vehicle can be driven at high speeds, maintaining correct tire inflation pressure is very important. Increased tire pressure and reduced vehicle loading may be required for high speed vehicle opera- tion. Refer to original equipment or an authorized tire dealer for recommended safe operating speeds, loading and cold tire inflation pressures.

WARNING!

High speed driving with your vehicle under maxi- mum load is dangerous. The added strain on your tires could cause them to fail. You could have a serious accident. Don’t drive a vehicle loaded to the maximum capacity at continuous speeds above 75
mph (120 km/h).

Radial-Ply Tires

WARNING!

Combining radial ply tires with other types of tires on your vehicle will cause your vehicle to handle poorly. The instability could cause an accident. Al- ways use radial tires in sets of four. Never combine them with other types of tires.

Cuts and punctures in radial tires are repairable only in the tread area because of sidewall flexing. Consult your dealer for radial tire repairs.

Tire Spinning When stuck in mud, sand, snow, or ice conditions, do not spin your vehicle’s wheels above 35 mph (55 km/h).

WARNING!

Fast spinning tires can be dangerous. Forces gener- ated by excessive wheel speeds may cause tire dam- age or failure. A tire could explode and injure someone. Do not spin your vehicle’s wheels faster than 35 mph (55 km/h) when you are stuck, and do not let anyone near a spinning wheel no matter what the speed.

STARTING AND OPERATING 257

Tread Wear Indicators Tread wear indicators are in the original equipment tires to help you in determining when your tires should be replaced.

258 STARTING AND OPERATING

These indicators are molded into the bottom of the tread grooves and will appear as bands when the tread depth becomes 1/16 inch (2 mm). When the indicators appear in 2 or more adjacent grooves, the tire should be replaced. Many states have laws requiring tire replacement at this point. Life of Tire The service life of a tire is dependent upon varying factors including but not limited to: • Driving style • Tire pressure • Distance driven

WARNING!

Tires and spare tire should be replaced after six years, regardless of the remaining tread. Failure to follow this warning can result in sudden tire failure. You could lose control and have an accident result- ing in serious injury or death.

Keep unmounted tires in a cool, dry place with as little exposure to light as possible. Protect tires from contact with oil, grease and gasoline.

Replacement Tires The tires on your new vehicle provide a balance of many characteristics. They should be inspected regularly for wear and correct cold tire inflation pressure. The manu- facturer strongly recommends that you use tires equiva- lent to the originals in size, quality and performance when replacement is needed (see the paragraph on tread wear indicators). Refer to the Tire and Loading Informa- tion placard for the size designation of your tire. The service description and load identification will be found on the original equipment tire. Failure to use equivalent replacement tires may adversely affect the safety, han- dling, and ride of your vehicle. We recommend that you contact your original equipment or an authorized tire dealer with any questions you may have on tire specifi- cations or capability.

STARTING AND OPERATING 259

WARNING!

• Do not use a tire, wheel size or rating other than that specified for your vehicle. Some combina- tions of unapproved tires and wheels may change suspension dimensions and performance charac- teristics, resulting in changes to steering, han- dling, and braking of your vehicle. This can cause unpredictable handling and stress to steering and suspension components. You could lose control and have an accident resulting in serious injury or death. Use only the tire and wheel sizes with load ratings approved for your vehicle. • Never use a tire with a smaller load index or capacity, other than what was originally equipped on your vehicle. Using a tire with a smaller load index could result in tire overloading and failure. You could lose control and have an accident. • Failure to equip your vehicle with tires having adequate speed capability can result in sudden tire failure and loss of vehicle control.

260 STARTING AND OPERATING

CAUTION!

TIRE CHAINS

Replacing original tires with tires of a different size may result in false speedometer and odometer readings.

CAUTION!

Alignment and Balance Poor suspension alignment may result in: • Fast tire wear. • Uneven tire wear, such as feathering and one-sided wear. • Vehicle pull to right or left. Tires may also cause the vehicle to pull left or right. Alignment will not correct this problem. See your autho- rized dealer for proper diagnosis. Improper alignment will not cause vehicle vibration. Vibration may be a result of tire and wheel out-of- balance. Proper balancing will reduce vibration and avoid tire cupping and spotty wear.

To avoid damage to your vehicle or tires, observe the following precautions: • Because of restricted chain clearance between tires and other suspension components, it is important that only chains in good condition are used. Broken chains can cause serious damage. Stop the vehicle immediately if noise occurs that could indicate chain breakage. Re- move the damaged parts of the chain before further use. • Install chains on the rear wheels as tightly as possible and then retighten after driving about 1⁄2 mile (0.8 km). • Do not exceed 30 mph (48 km/h). • Drive cautiously and avoid severe turns and large • Do not drive for prolonged period on dry pavement. • Observe the tire chain manufacturer’s instructions on the method of installation, operating speed, and condi- tions for use. Always use the lower suggested operating speed of the chain manufacturer if different than the speed recommended by the manufacture.

In order to avoid damage to tires, chains, and NOTE: your vehicle do not drive for a prolonged period of time on dry pavement. Observe the tire chain manufacturer’s instructions on method of installation, operating speed, and conditions for usage. Always use the lower suggested operating speed if both the chain manufacturer and vehicle manufacturer sug- gest a maximum speed. This notice applies to all chain traction devices, including link and cable (radial) chains.

STARTING AND OPERATING 261

TIRE ROTATION RECOMMENDATIONS Tires on the front and rear axles of vehicles operate at different loads and perform different steering, handling, and braking functions. For these reasons, they wear at unequal rates, and develop irregular wear patterns. These effects can be reduced by timely rotation of tires. The benefits of rotation are especially worthwhile with aggressive tread designs such as those on On/Off Road type tires. Rotation will increase tread life, help to main- tain mud, snow, and wet traction levels, and contribute to a smooth, quiet ride. Follow the recommended tire rotation frequency for your type of driving found in the “Maintenance Schedules” Section of this manual. More frequent rotation is permis- sible if desired. The reasons for any rapid or unusual wear should be corrected prior to rotation being per- formed.

262 STARTING AND OPERATING

NOTE: The Premium Tire Pressure Monitor System will automatically locate the pressure values displayed in the correct vehicle position following a tire rotation. The suggested rotation method is the “forward-cross” shown in the following diagram.

TIRE PRESSURE MONITOR SYSTEM (TPMS) The Tire Pressure Monitoring System (TPMS) will warn the driver of a low tire pressure based on the vehicle recommended cold tire pressure. The tire pressure will vary with temperature by about 1
psi (7 kPa) for every 12°F (–11°C). This means that when the outside temperature decreases, the tire pressure will decrease. Tire pressure should always be set based on cold inflation tire pressure. This is defined as the tire pressure after a vehicle has not been driven for more than 3 hours - and in outside ambient temperature. Refer to the “Tires – General Information” in this section for information on how to properly inflate the vehicle’s tires. The tire pressure will also increase as the vehicle is driven - this is normal and there should be no adjustment for this increased pressure.

The TPM System will warn the driver of a low tire pressure if the tire pressure falls below the low pressure warning threshold for any reason, including low tem- perature effects. The TPM System will continue to warn the driver of low tire pressure as long as the condition exists, and will not turn off until the tire pressure is at or above recom- mended cold tire pressure. Once the “Tire Pressure Monitoring Telltale Light” has been illuminated, the tire pressure must be increased to the recommended cold tire pressure in order for the “Tire Pressure Monitoring Telltale Light” to be turned off. The system will automati- cally update, and the “Tire Pressure Monitoring Telltale Light” will extinguish once the updated tire pressures have been received. The vehicle may need to be driven for up to 10 minutes above 15 mph (24 km/h) to receive this information.

STARTING AND OPERATING 263

For example, your vehicle has a recommended cold (parked for more than 3 hours) tire pressure of 33 psi (227
kPa). If the ambient temperature is 68°F (20°C) and the measured tire pressure is 28 psi (193 kPa), a temperature drop to 20°F (-7°C) will decrease the tire pressure to approximately 24 psi (165 kPa). This tire pressure is sufficiently low enough to turn ON the “Tire Pressure Monitoring Telltale Light.” Driving the vehicle may cause the tire pressure to rise to approximately 28 psi (193 kPa), but the “Tire Pressure Monitoring Telltale Light” will still be ON. In this situation, the “Tire Pressure Monitoring Telltale Light” will turn OFF only after the tires have been inflated to the vehicle’s recommended cold tire pressure value. NOTE: Seasonal temperature changes will affect tire pressure, and the TPM system will monitor the actual tire pressure in the tire.

264 STARTING AND OPERATING

Base System — If Equipped The Tire Pressure Monitor System (TPMS) uses wireless technology with wheel rim mounted electronic sensors to monitor tire pressure levels. Sensors, mounted to each wheel as part of the valve stem, transmit tire pressure readings to the Receiver Module. It is particularly important, for you to check the NOTE: tire pressure in all of your tires regularly and to maintain the proper pressure. The Tire Pressure Monitor System (TPMS) consists of the following components: • Receiver Module • 4 Tire Pressure Monitoring Sensors • Tire Pressure Monitoring Telltale Light A tire pressure monitoring sensor is located in the spare wheel if the vehicle is equipped with a matching full size

spare wheel and tire assembly. The matching full size spare tire can be used in place of any of the four road tires.

The “Tire Pressure Monitoring Telltale Light” will illuminate in the instrument cluster, and an au- dible chime will be activated when one or more of the four active road tire pressures are low. The audible chime will sound once every ignition cycle for each condition that it detects. Should this occur, you should stop as soon as possible, check the inflation pressure of each tire on your vehicle, and inflate each tire to the vehicle’s recommended cold tire pressure. The system will automatically update, and the “Tire Pressure Moni- toring Light” will extinguish once the updated tire pres- sures have been received. The vehicle may need to be driven for up to 10 minutes above 15 mph (24 km/h) to receive this information. A low spare tire will not cause the “Tire Pressure Monitoring Telltale Light” to illumi- nate or the chime to sound.

The “Tire Pressure Monitoring Telltale Light” will flash on and off for 60 seconds, and an audible chime will sound when a system fault is detected. The flash cycle will repeat every ten minutes, without an audible chime, until the fault condition no longer exists. If the ignition key is cycled, this sequence will repeat, providing the system fault still exists. In the event that the matching full size spare tire NOTE: is swapped with a low pressure road tire, the next ignition key cycle will still show the “Tire Pressure Monitoring Telltale Light” to be ON, and a chime to sound. Driving the vehicle for up to 10 minutes above 15
mph (24 km/h) will turn OFF the “Tire Pressure Moni- toring Telltale Light” as long as the spare tire or any other road tire(s) are not below the low pressure warning threshold.

STARTING AND OPERATING 265

CAUTION!

The TPMS has been optimized for the original equipment tires and wheels. TPMS pressures have been established for the tire size equipped on your vehicle. Undesirable system operation or sensor damage may result when using replacement equip- ment that is not of the same size, type, and/or style. After-market wheels can cause sensor damage. Do not use tire sealant from a can, or balance beads if your vehicle is equipped with a TPMS, as damage to the sensors may result.

266 STARTING AND OPERATING

CAUTION!

After inspecting or adjusting the tire pressure al- ways reinstall the valve stem cap. This will prevent moisture and dirt from entering the valve stem, which could damage the Tire Pressure Monitoring Sensor.

NOTE: • The TPMS is not intended to replace normal tire care and maintenance, or to provide warning of a tire failure or condition. • The TPMS should not be used as a tire pressure gauge • Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure.

while adjusting your tire pressure.

Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. • The TPMS is not a substitute for proper tire mainte- nance, and it is the driver’s responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the “Tire Pressure Monitoring Telltale Light.”

Base System with Electronic Vehicle Information Center (EVIC)– If Equipped The Tire Pressure Monitor System (TPMS) uses wireless technology with wheel rim mounted electronic sensors to monitor tire pressure levels.

FUEL REQUIREMENTS (GASOLINE ENGINES)

Your engine is designed to meet all emis- sions regulations and provide excellent fuel economy and performance when us- ing high quality unleaded gasoline having an octane rating of 87. The use of premium gasoline is not recommended. The use of premium gasoline will provide no benefit over high quality regular gasoline, and in some circumstances may result in poorer performance. Mid-grade gasoline (89 octane) will enhance engine per- formance during the following conditions: • Hot weather • Towing • Hard accelerations • Hilly terrain • Low humidity

STARTING AND OPERATING 273

Light spark knock at low engine speeds is not harmful to your engine. However, continued heavy spark knock at high speeds can cause damage and immediate service is required. Poor quality gasoline can cause problems such as hard starting, stalling and hesitations. If you experience these symptoms, try another brand of “regular” gasoline be- fore considering service for the vehicle. Over 40 auto manufacturer’s world wide have issued and endorsed consistent gasoline specifications (the World- wide Fuel Charter, WWFC) to define fuel properties necessary to deliver enhanced emissions, performance, and durability for your vehicle. The manufacturer recom- mends the use of gasoline that meets the WWFC speci- fications if they are available.

274 STARTING AND OPERATING

Reformulated Gasoline Many areas of the country require the use of cleaner burning gasoline referred to as “Reformulated Gasoline.” Reformulated gasolines contain oxygenates, and are spe- cifically blended to reduce vehicle emissions and im- prove air quality. The manufacturer supports the use of reformulated gaso- lines. Properly blended reformulated gasolines will pro- vide excellent performance and durability of engine and fuel system components. Gasoline/Oxygenate Blends Some fuel suppliers blend unleaded gasoline with oxy- genates such as 10% ethanol, MTBE, and ETBE. Oxygen- ates are required in some areas of the country during the winter months to reduce carbon monoxide emissions. Fuels blended with these oxygenates may be used in your vehicle.

CAUTION!

DO NOT use gasolines containing Methanol or E85
Ethanol. Use of these blends may result in starting and driveability problems and may damage critical fuel system components.

Problems that result from using methanol/gasoline or E85 Ethanol blends are not the responsibility of the manufacturer. While MTBE is an oxygenate made from Methanol, it does not have the negative effects of Metha- nol. MMT In Gasoline MMT is a manganese containing metallic additive that is blended into some gasoline to increase the octane num- ber. Gasolines blended with MMT offer no performance advantage beyond gasolines of the same octane number without MMT. Gasolines blended with MMT have shown

to reduce spark plug life and reduce emission system performance in some vehicles. The manufacturer recom- mends using gasolines without MMT. Since the MMT content of gasoline may not be indicated on the pump, you should ask your gasoline retailer whether or not his/her gasoline contains MMT. It is even more important to look for gasoline without MMT in Canada, because MMT can be used at levels higher than allowed in the United States. MMT is prohibited in Federal and California reformu- lated gasolines. Materials Added To Fuel All gasoline sold in the United States is required to contain effective detergent additives. Use of additional detergents or other additives are not needed under normal conditions and would result in additional cost. Therefore you should not have to add anything to the fuel.

Fuel System Cautions

CAUTION!

Follow these guidelines to maintain your vehicle’s performance: • The use of leaded gas is prohibited by Federal law. Using leaded gasoline can impair engine performance, damage the emission control system. • An out-of-tune engine, or certain fuel or ignition malfunctions, can cause the catalytic converter to overheat. If you notice a pungent burning odor or some light smoke, your engine may be out of tune or malfunctioning and may require immediate service. Contact your dealer for service assistance.

276 STARTING AND OPERATING

• The use of fuel additives which are now being sold as octane enhancers is not recommended. Most of these products contain high concentrations of methanol. Fuel system damage or vehicle performance problems resulting from the use of such fuels or additives is not the responsibility of the manufacturer.

NOTE: systems can result against you.

Intentional tampering with emissions control in civil penalties being assessed

Carbon Monoxide Warnings

WARNING!

Carbon monoxide (CO) in exhaust gases is deadly. Follow the precautions below to prevent carbon monoxide poisoning: • Do not inhale exhaust gases. They contain carbon monoxide, a colorless and odorless gas which can kill. Never run the engine in a closed area, such as a garage, and never sit in a parked vehicle with the engine running for an extended period. If the vehicle is stopped in an open area with the engine running for more than a short period, adjust the ventilation system to force fresh, outside air into the vehicle. • Guard against carbon monoxide with proper mainte- nance. Have the exhaust system inspected every time

the vehicle is raised. Have any abnormal conditions repaired promptly. Until repaired, drive with all side windows fully open. • Keep the swing gate closed when driving your vehicle to prevent carbon monoxide and other poisonous exhaust gases from entering the vehicle.

ADDING FUEL

CAUTION!

DO NOT put gasoline in your diesel vehicle (if equipped). If you accidentally put gasoline in your vehicle, DO NOT start the engine. This will cause damage to the fuel system. Have the fuel system flushed.

CAUTION!

CAUTION!

Damage to the fuel system or emission control system could result from using an improper fuel cap (gas cap). A poorly fitting cap could let impurities into the fuel system. Also, a poorly fitting after- market cap can cause the MIL (Malfunction Indica- tor Light) to illuminate, due to fuel vapors escaping from the system.

CAUTION!

A poorly fitting gas cap may cause the Malfunction Indicator Light to turn on.

To avoid fuel spillage and overfilling, do not “top off” the fuel tank after filling.

NOTE: When the fuel nozzle “clicks” or shuts off, the fuel tank is full.

WARNING!

• Never have any smoking materials lit in or near the vehicle when the gas cap is removed or the tank filled. • Never add fuel when the engine is running. This is in violation of most state and federal fire regulations and will cause the malfunction indi- cator light to turn on.

NOTE: Tighten the gas cap about 1/4 turn until you hear one click. This is an indication that cap is properly tightened. If the gas cap is not tighten properly, the Malfunction Indicator Light will come on. Be sure the gas cap is tightened every time the vehicle is refueled.

WARNING!

A fire may result if gasoline is pumped into a portable container that is inside of a vehicle. You could be burned. Always place gas containers on the ground while filling.

STARTING AND OPERATING 279

Loose Fuel Filler Cap Message If the vehicle diagnostic system determines that the fuel filler cap is loose, improperly installed, or damaged, a “CHECK GASCAP” message will be displayed in the EVIC (Electronic Vehicle Information Center). Refer to “Electronic Vehicle Information Center” in Section 4 of this manual. Tighten the fuel filler cap until a “clicking” sound is heard. This is an indication that the fuel filler cap is properly tightened. Refer to “Onboard Diagnostic System — OBDII” in Section 7 of this manual for more information.

CAUTION!

Damage to the fuel system or emission control system could result from using an improper fuel tank filler cap (gas cap). A poorly fitting cap could let impurities into the fuel system.

VEHICLE LOADING

Certification Label As required by National Highway Traffic Safety Admin- istration Regulations, your vehicle has a certification label affixed to the driver’s side door or pillar. This label contains the month and year of manufacture, Gross Vehicle Weight Rating (GVWR), Gross Axle Weight Rating (GAWR) front and rear, and Vehicle Identification Number (VIN). A Month-Day-Hour (MDH) number is included on this label and indicates the Month, Day and

Hour of manufacture. The bar code that appears on the bottom of the label is your Vehicle Identification Number (VIN). Gross Vehicle Weight Rating (GVWR) The GVWR is the total permissible weight of your vehicle including driver, passengers, vehicle, options, trailer tongue weight, and cargo. The label also specifies maxi- mum capacities of front and rear axle systems (GAWR). Total load must be limited so GVWR and front and rear GAWR are not exceeded. Payload The payload of a vehicle is defined as the allowable load weight a truck can carry, including the weight of the driver, all passengers, options and cargo. Gross Axle Weight Rating (GAWR) The GAWR is the maximum permissible load on the front and rear axles. The load must be distributed in the cargo area so that the GAWR of each axle is not exceeded.

Each axle GAWR is determined by the components in the system with the lowest load carrying capacity (axle, springs, tires or wheels). Heavier axles or suspension components sometimes specified by purchasers for in- creased durability does not necessarily increase the vehi- cle’s GVWR. Tire Size The tire size on the Label represents the actual tire size on your vehicle. Replacement tires must be equal to the load capacity of this tire size. Rim Size This is the rim size that is appropriate for the tire size listed. Inflation Pressure This is the cold tire inflation pressure for your vehicle for all loading conditions up to full GAWR.

STARTING AND OPERATING 281

Curb Weight The curb weight of a vehicle is defined as the total weight of the vehicle with all fluids, including vehicle fuel, at full capacity conditions, and with no occupants or cargo loaded into the vehicle. The front and rear curb weight values are determined by weighing your vehicle on a commercial scale before any occupants or cargo are added. Loading The actual total weight and the weight of the front and rear of your vehicle at the ground can best be determined by weighing it when it is loaded and ready for operation. The entire vehicle should first be weighed on a commer- cial scale to insure that the GVWR has not been exceeded. The weight on the front and rear of the vehicle should then be determined separately to be sure that the load is properly distributed over front and rear axle. Weighing the vehicle may show that the GAWR of either the front or rear axles has been exceeded but the total load is

282 STARTING AND OPERATING

within the specified GVWR. If so, weight must be shifted from front to rear or rear to front as appropriate until the specified weight limitations are met. Store the heavier items down low and be sure that the weight is distributed equally. Stow all loose items securely before driving. Improper weight distributions can have an adverse effect on the way your vehicle steers and handles and the way the brakes operate.

CAUTION!

Do not load your vehicle any heavier than the GVWR or the maximum front and rear GAWR. If you do, parts on your vehicle can break, or it can change the way your vehicle handles. This could cause you to lose control. Also overloading can shorten the life of your vehicle.

TRAILER TOWING In this section you will find safety tips and information on limits to the type of towing you can reasonably do with your vehicle. Before towing a trailer carefully re- view this information to tow your load as efficiently and safely as possible. To maintain warranty coverage, follow the requirements and recommendations in this manual concerning ve- hicles used for trailer towing. Common Towing Definitions The following trailer towing related definitions will assist you in understanding the following information: Gross Vehicle Weight Rating (GVWR) The GVWR is the total allowable weight of your vehicle. This includes driver, passengers, cargo and tongue weight. The total load must be limited so that you do not exceed the GVWR.

Gross Trailer Weight (GTW) The gross trailer weight (GTW) is the weight of the trailer plus the weight of all cargo, consumables and equipment (permanent or temporary) loaded in or on the trailer in its ⬙loaded and ready for operation⬙ condition. The recom- mended way to measure GTW is to put your fully loaded trailer on a vehicle scale. The entire weight of the trailer must be supported by the scale. Gross Combination Weight Rating (GCWR) The gross combination weight rating (GCWR) is the total permissible weight of your vehicle and trailer when weighed in combination. (Note that GCWR ratings in- clude a 150 lbs (68 kg) allowance for the presence of a driver).

STARTING AND OPERATING 283

Gross Axle Weight Rating (GAWR) The GAWR is the maximum capacity of the front and rear axles. Distribute the load over the front and rear axles evenly. Make sure that you do not exceed either front or rear GAWR.

WARNING!

It is important that you do not exceed the maximum front or rear GAWR. A dangerous driving condition can result if either rating is exceeded. You could lose control of the vehicle and have an accident.

Tongue Weight (TW) The downward force exerted on the hitch ball by the trailer. In most cases it should not be less than 10% or more than 15% of the trailer load. You must consider this as part of the load on your vehicle.

284 STARTING AND OPERATING

Frontal Area The maximum height and maximum width of the front of a trailer. Trailer Sway Control The trailer sway control is a telescoping link that can be installed between the hitch receiver and the trailer tongue that typically provides adjustable friction associated with the telescoping motion to dampen any unwanted trailer swaying motions while traveling. Weight-Carrying Hitch A weight-carrying hitch supports the trailer tongue weight, just as if it were luggage located at a hitch ball or some other connecting point of the vehicle. These kind of hitches are the most popular on the market today and they’re commonly used to tow small- and medium-sized trailers.

Weight-Distributing Hitch A weight-distributing system works by applying lever- age through spring (load) bars. They are typically used for heavier loads, to distribute trailer tongue weight to the tow vehicle’s front axle and the trailer axle(s). When used in accordance with the manufacturers’ directions, it provides for a more level ride, offering more consistent steering and brake control thereby enhancing towing safety. The addition of a friction/hydraulic sway control also dampens sway caused by traffic and crosswinds and contributes positively to tow vehicle and trailer stability. Trailer sway control and a weight distributing (load equalizing) hitch are recommended for heavier Tongue Weights (TW) and may be required depending on Vehicle and Trailer configuration/loading to comply with gross axle weight rating (GAWR) requirements.

WARNING!

An improperly adjusted Weight Distributing Hitch system may reduce handling, stability, braking per- formance, and could result in an accident. Weight Distributing Systems may not be compatible with Surge Brake Couplers. Consult with your hitch and trailer manufacturer or a reputable Recreational Vehicle dealer for additional information.

Refer to local laws for maximum trailer towing speeds.

NOTE: The trailer tongue weight must be considered as part of the combined weight of occupants and cargo, and should never exceed the weight referenced on the Tire and Loading Information placard. Refer to the Tire– Safety Information section in this manual. Trailer and Tongue Weight Always load a trailer with 60% to 65% of the weight in the front of the trailer. This places 10% to 15% of the Gross Trailer Weight (GTW) on the tow hitch of your vehicle. Loads balanced over the wheels or heavier in the rear can cause the trailer to sway severely side to side which will cause loss of control of vehicle and trailer. Failure to load trailers heavier in front is the cause of many trailer accidents. Never exceed the maximum tongue weight stamped on your bumper or trailer hitch.

Consider the following items when computing the weight on the rear axle of the vehicle: • The tongue weight of the trailer. • The weight of any other type of cargo or equipment • The weight of the driver and all passengers.

put in or on your vehicle.

290 STARTING AND OPERATING

NOTE: Remember that everything put into or on the trailer adds to the load on your vehicle. Also, additional factory-installed options, or dealer-installed options, must be considered as part of the total load on your vehicle. Refer to the Tire and Loading Information plac- ard in the Tire Safety Information section of this manual for the maximum combined weight of occupants and cargo for your vehicle. Towing Requirements To promote proper break-in of your new vehicle driv- etrain components the following guidelines are recom- mended:

CAUTION!

• Avoid towing a trailer for the first 500 miles (805
km) of vehicle operation. Doing so may damage your vehicle. • During the first 500 miles (805 km) of trailer

towing, limit your speed to 50 mph (80 km/h).

Perform the maintenance listed in Section 8 of this manual. When towing a trailer, never exceed the GAWR, or GCWR, ratings.

WARNING!

Improper towing can lead to an injury accident. Follow these guidelines to make your trailer towing as safe as possible: Make certain that the load is secured in the trailer and will not shift during travel. When trailering cargo that is not fully secured, dynamic load shifts can occur that may be difficult for the driver to control. You could lose control of your vehicle and have an accident. • When hauling cargo or towing a trailer, do not over- load your vehicle or trailer. Overloading can cause a loss of control, poor performance or damage to brakes, axle, engine, transmission, steering, suspension, chas- sis structure or tires.

STARTING AND OPERATING 291

• Safety chains must always be used between your vehicle and trailer. Always connect the chains to the frame or hook retainers of the vehicle hitch. Cross the chains under the trailer tongue and allow enough slack for turning corners. • Vehicles with trailers should not be parked on a grade. When parking, apply the parking brake on the tow vehicle. Put the tow vehicle automatic transmission in P for Park. With a manual transmission, shift the transmission into reverse. And with four-wheel-drive vehicles, make sure the transfer case is not in neutral. Always, block or ⬙chock⬙ the trailer wheels.

• GCWR must not be exceeded. • Total weight must be distributed between the tow vehicle and the trailer such that the following four ratings are not exceeded: 1. GVWR

292 STARTING AND OPERATING

2. GTW 3. GAWR 4. Tongue weight rating for the trailer hitch utilized (This requirement may limit the ability to always achieve the 10% to 15% range of tongue weight as a percentage of total trailer weight).

Towing Requirements — Tires − Do not attempt to tow a trailer while using a compact

spare tire.

− Proper tire inflation pressures are essential to the safe and satisfactory operation of your vehicle. Refer to the Tires–General Information section of this manual on Tire Pressures for proper tire inflation procedures.

− Check for signs of tire wear or visible tire damage before towing a trailer. Refer to the Tires–General Information section of this manual on Tread Wear Indicators for the proper inspection procedure.

− When replacing tires, refer to the Tires–General Infor- mation section of this manual on Replacement Tires for proper tire replacement procedures. Replacing tires with a higher load carrying capacity will not increase the vehicle’s GVWR and GAWR limits. Towing Requirements — Trailer Brakes − Do not interconnect the hydraulic brake system or vacuum system of your vehicle with that of the trailer. This could cause inadequate braking and possible personal injury.
