2005 Dodge RAM SRT10 Owners Manual

Never use Park position on an automatic transmis- sion as a substitute for the parking brake. Always apply parking brake fully when parked to guard against vehicle movement and possible injury or damage.

WARNING!

Your vehicle could move and injure you and others if it is not completely in P (Park). Check by trying to move the gearshift lever back and forth without first pulling it toward you after you have set it in P. Make sure it is in Park before leaving the vehicle.

WARNING!

It is dangerous to shift the selector lever out of “P” or “N” if the engine speed is higher than idle speed. If your foot is not firmly on the brake pedal, the vehicle could accelerate quickly forward or in re- verse. You could lose control of the vehicle and hit someone or something. Only shift into gear when the engine is idling normally and when your right foot is firmly on the brake pedal.

“R” Reverse Use this range only after the vehicle has come to a complete stop.

STARTING AND OPERATING 167

“N” Neutral Shift to Neutral when the vehicle is standing for pro- longed periods with the engine running. The engine may be started in this range. Set the parking brake if you must leave the vehicle. “D” Drive This position provides all forward gears, including 3rd gear direct and 4th gear overdrive (see Overdrive Opera- tion). Use this range for most city and highway driving. “2” Second Use this position for driving slowly in heavy city traffic or on mountain roads where more precise speed control is desirable. Use it also when climbing long grades, and for engine braking when descending moderately steep grades. NOTE: Do not exceed maximum engine speed.

168 STARTING AND OPERATING

“1” First Use this position for driving up very steep hills and for engine braking at low speeds (20 mph [32 km/h] or less) when going downhill. NOTE: Do not exceed a maximum engine speed of 5500
rpm. Overdrive Operation The overdrive automatic transmission contains an elec- tronically controlled fourth speed (Overdrive). The trans- mission will automatically shift from Drive to Overdrive if the following conditions are present: • the transmission selector is in Drive; • the engine coolant has reached normal operating tem- • vehicle speed is above approximately 30 mph (48

perature;

km/h);

• the “TOW/HAUL” switch has not been activated; • transmission has reached normal operating tempera-

ture. If the vehicle is started in extremely cold tem- NOTE: peratures, the transmission may not shift into Overdrive and will automatically select the most desirable gear for operation at this temperature. Normal operation will resume when the transmission fluid temperature has risen to a suitable level. Refer also to the Note under torque converter clutch, later in this section. If the transmission temperature gets extremely hot, the transmission will automatically select the most desirable gear for operation at this temperature. If the transmission temperature becomes hot enough the TRANS TEMP light may illuminate and the transmission may downshift out of Overdrive until the transmission cools down. After cooldown, the transmission will resume normal opera- tion.

The transmission will downshift from Overdrive to Drive if the accelerator pedal is fully depressed at vehicle speeds above approximately 35 mph (56 km/h). Overdrive Operation The four-speed overdrive automatic transmission con- tains an electronically controlled fourth speed (Over- drive). The transmission will automatically shift from Drive to Overdrive if the following conditions are present:

• the transmission selector is in Drive; • the engine coolant has reached normal operating tem- • vehicle speed is above approximately 30 mph (48
• the “TOW/HAUL” switch has not been activated;

km/h);

170 STARTING AND OPERATING

• transmission has reached normal operating tempera-

ture.

The transmission will downshift from Overdrive to Drive if the accelerator pedal is fully depressed at vehicle speeds above approximately 35 mph (56 km/h). Overdrive can be locked out by pressing the “TOW/ HAUL” button located on the selector lever. The “TOW/ HAUL” light will illuminate in the instrument cluster to indicate that the switch has been activated. Pressing the switch a second time restores the Overdrive function. If the “TOW/HAUL” feature is desired, the“TOW/HAUL” button must be pressed each time the engine is started. If the vehicle is started in extremely cold tem- NOTE: peratures, the transmission may not shift into Overdrive and will automatically select the most desirable gear for operation at this temperature. Normal operation will resume when the transmission fluid temperature has

risen to a suitable temperature. Refer also to the Note under torque converter clutch, later in this section. If the transmission temperature gets extremely hot, the transmission will automatically select the most desirable gear for operation at this temperature. If the transmission temperature becomes hot enough the “TOW/HAUL” and/or TRANS TEMP light(s) may illuminate and the transmission may downshift out of Overdrive until the transmission cools down. After cooldown, the transmis- sion will resume normal operation. When To Lock Out Overdrive When driving in hilly areas, towing a trailer, carrying a heavy load, etc., and frequent 4–3–4 transmission shifting occurs, press the “TOW/HAUL” button. This will im- prove performance and reduce the potential for transmis- sion overheating or failure due to excessive shifting. The “TOW/HAUL” light will illuminate in the instru- ment cluster to indicate when the switch has been

activated. Pressing the switch a second time restores normal operation. If the “TOW/HAUL” mode is desired, the button must be pressed each time the engine is started. Torque Converter Clutch A feature, designed to improve fuel economy, has been included in the automatic transmission on your vehicle. A clutch within the torque converter engages automati- cally at calibrated speeds. This may result in a slightly different feeling or response during normal operation in high gear. When the vehicle speed drops or during acceleration when the transmission downshifts to second gear, the clutch automatically disengages. NOTE: The torque converter clutch will not engage until the transmission fluid and engine coolant are warm [usually after 1-3 miles (1.6 - 4.8 km) of driving]. Because the engine speed is higher when the torque converter clutch is not engaged, it may seem as if the transmission

STARTING AND OPERATING 171

is not shifting into Overdrive when cold. This is normal. Pressing the “TOW/HAUL” button, when the transmis- sion is sufficiently warm, will demonstrate that the transmission is able to shift into and out of overdrive. If the vehicle has not been driven in several NOTE: days, the first few seconds of operation after shifting the transmission into gear may seem sluggish. This is due to the fluid partially draining from the torque converter into the transmission. This condition is normal and will not cause damage to the transmission. The torque converter will refill within five seconds of shifting from Park into any other gear position. Manual Transmission — 6-Speed

NOTE: The parking brake should be engaged before leaving the vehicle, especially on an incline.

172 STARTING AND OPERATING

This model is equipped with a clutch interlocking igni- tion system. The clutch pedal must be fully depressed to start the vehicle. Fully depress the clutch pedal before shifting gears. As you release the clutch pedal, lightly depress the accelera- tor pedal. When launching a stationary vehicle, keep the engine speed low until the clutch is fully engaged.

Damage to the clutch can re- sult from starting in 2nd or 3rd gear with a loaded ve- hicle. Use each gear in nu- merical order – do not skip a gear.

For improved clutch life, all six forward gears should be used. For steady highway driving with light acceleration, 6th gear is recommended. When shifting from 4th to 5th gear, apply side effort away and forward without push- ing hard enough to engage Reverse gear. Shifting from 5th to 6th requires the same side effort or the lever will return to center resulting in a shift into 4th gear and damage the transmission, clutch, or engine. You should use low gear when starting from a standing position if under a heavy load. To shift into Reverse, come to a complete stop. Depress the clutch and pause briefly to allow the gear train to stop. Move the shift lever from the Neutral position straight across and up into Reverse. Never drive with your foot resting on the clutch pedal, or attempt to hold the vehicle on a hill with the clutch pedal partially engaged, as this will cause abnormal wear on the clutch.

Recommended Shift Speeds To use your manual transmission for fuel economy it should be upshifted as listed below. Shift at the vehicle speeds listed for acceleration. Earlier upshifts during cruise conditions (relatively steady speeds) will result in increased fuel economy, and may be used as indicated.

STARTING AND OPERATING 173

Downshifting Moving from a high gear down to a lower gear is recommended to preserve brakes when driving down steep hills. In addition, downshifting at the right time provides better acceleration when you desire to resume speed. Downshifting progressively. Do not skip gears to avoid overspeeding the engine and clutch. For accelera- tion at speeds less than 15 mph (25 km/h), 2nd gear is recommended.

CAUTION!

When descending a hill, be very careful to downshift one gear at a time to prevent overspeeding the engine which can cause valve damage.

174 STARTING AND OPERATING

LIMITED-SLIP DIFFERENTIAL The limited-slip differential provides additional traction on snow, ice, mud, sand and gravel, particularly when there is a difference between the traction characteristics of the surface under the right and left rear wheels. During normal driving and cornering, the limited-slip unit per- forms similarly to a conventional differential. On slip- pery surfaces, however, the differential delivers more of the driving effort to the rear wheel having the better traction. The limited-slip differential is especially helpful during slippery driving conditions. With both rear wheels on a slippery surface, a slight application of the accelerator will supply maximum traction. When starting with only one rear wheel on an excessively slippery surface, slight momentary application of the parking brake may be necessary to gain maximum traction.

WARNING!

On vehicles equipped with a limited-slip differen- tial, never run the engine with one rear wheel off the ground, since the vehicle may drive through the rear wheel remaining on the ground. You could lose control of the vehicle.

Care should be taken to avoid sudden accelerations when both rear wheels are on a slippery surface. This could cause both rear wheels to spin, and allow the vehicle to slide sideways on the crowned surface of a road or in a turn.

PARKING BRAKE The foot operated parking brake is positioned below the lower left corner of the instrument panel. To release the parking brake, pull the parking brake release handle. NOTE: The instrument cluster red brake warning light will come on and flash to indicate that the parking brake is applied. You must be sure that the parking brake is fully applied before leaving the vehicle.

STARTING AND OPERATING 175

Be sure the parking brake is firmly set when parked and the gear shift lever is in the REVERSE position.

176 STARTING AND OPERATING

WARNING!

• Always fully apply the parking brake when leav- ing your vehicle, or it may roll and cause damage or injury. Also be certain to leave a manual transmission in Reverse or first gear. Failure to do so may allow the vehicle to roll and cause damage or injury. • Leaving children in a vehicle unattended is dan- gerous 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.

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.

BRAKE SYSTEM If power assist is lost for any reason (for example, repeated brake applications with the engine off), the brakes will still function. However, you will experience a substantial increase in braking effort to stop the vehicle. If either the front or rear hydraulic systems lose normal capability, the remaining system will still function with some loss of overall braking effectiveness. This will be evident by increased pedal travel during application, greater pedal force required to slow or stop, and activa- tion of the BRAKE warning lamp and the ABS lamp (if equipped) during brake use.

Brake Noise During normal operation of the brake system certain noises may be present from time to time. Occasional ⬙groan⬙ or ⬙squeal⬙ noises may occur during normal operation of the brake system which may not be indica- tive of a problem. These noises may be heard at any time the brakes are applied but may be more noticeable during the first few brake applications in the morning. Moisture, hot or cold temperature, dust, and or other debris may also contribute to the noise condition. Repeated or con- tinuous noises during braking may be an indication that the brake linings are worn and in need of replacement. Four-Wheel Anti-Lock Brake System (ABS) This 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 lockup and help avoid skidding on slippery surfaces.

STARTING AND OPERATING 177

The system’s pump motor runs during an ABS stop to provide regulated hydraulic pressure. The pump motor makes a low humming noise during operation. This is normal. When you are in a severe braking condition involving use of the Anti-lock Brake System, you will experience some pedal drop as the vehicle comes to a complete stop. This is the result of the system reverting to the base brake system and is normal. Engagement of the Anti-lock Brake System may be accompanied by a pulsing sensation. You may also hear a clicking noise. These occurrences are normal, and indi- cate that the system is functioning. ABS Warning Light The Anti-lock Brake System includes an amber warning light. When the light is illuminated, the Anti-lock Brake System is not functioning. The system reverts to standard non-anti-lock brakes.

178 STARTING AND OPERATING

WARNING!

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.

• 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.

POWER STEERING Your power steering system will provide mechanical steering capability if power assist is lost. If for any reason the hydraulic pressure is interrupted, it will still be possible to steer your vehicle. Under these conditions you will experience a substantial increase in steering effort.

Tire Loading and Tire Pressure

Tire Placard Location NOTE: The proper cold tire inflation pressure for pas- senger cars is listed on either the face of the driver’s door or the driver’s side “B” pillar. For vehicles other than passenger cars, the cold tire inflation pressures are listed on either the “B” pillar, the Certification Label or in the Tire Inflation Pressures brochure in the glove compart- ment.

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.

STARTING AND OPERATING 185

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

186 STARTING AND OPERATING

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.)

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).

STARTING AND OPERATING 187

188 STARTING AND OPERATING

WARNING!

1. Safety—

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. • Over inflated 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 inflated to the recom- mended cold tire inflation pressure.

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. Underinflation also increases tire rolling resistance and results in higher fuel consumption. 3. Ride Comfort and Vehicle Stability— Proper tire inflation contributes to a comfortable ride. Overinflation produces a jarring and uncomfortable ride. Tire Inflation Pressures The proper cold tire inflation pressure for passenger cars is listed on either the face of the driver’s door or the driver’s side “B” pillar. For vehicles other than passenger cars, the cold tire inflation pressures are listed on either the “B” pillar, the Certification Label or in the Tire Inflation Pressures brochure in the glove compartment. Some vehicles may have Supplemental Tire Pressure Information for vehicle loads that are less than the

STARTING AND OPERATING 189

maximum loaded vehicle condition. These pressure con- ditions will be found in the “Supplemental Tire Pressure Information” section of this manual.

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

190 STARTING AND OPERATING

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 1mile (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.

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.

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.

STARTING AND OPERATING 191

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).

192 STARTING AND OPERATING

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 ply tires in sets of four (or 6, in case of trucks with dual rear wheels). 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 authorized tire dealer for radial tire repairs.

Compact Spare Tire — If Equipped The compact spare is for temporary emergency use with radial tires. It is engineered to be used on your style vehicle only. Since this tire has limited tread life, the original tire should be repaired (or replaced) and rein- stalled at the first opportunity.

WARNING!

Temporary use spare tires are for emergency use only. With these tires, do not drive more than 50 mph (80 km/h). Temporary-use spare tires have limited tread life. When two or more tread wear indicators appear in adjacent grooves, the temporary use spare tire needs to be replaced. Be sure to follow the warnings which apply to your spare. Failure to do so could result in spare tire failure and loss of vehicle control.

Do not install a wheel cover or attempt to mount a conventional tire on the compact spare wheel, since the wheel is designed specifically for the compact spare. Do not install more than one compact spare tire/wheel on the vehicle at any given time.

CAUTION!

Because of the reduced ground clearance, do not take your vehicle through an automatic car wash with the compact spare installed. Damage to the vehicle may result.

STARTING AND OPERATING 193

Limited Use Spare — If Equipped The limited use spare tire is for temporary emergency use on your vehicle. This tire is identified by a limited use spare tire warning label located on the limited use spare tire and wheel assembly. This tire may look like the original equipped tire on the front or rear axle of your vehicle, but it is not. Installation of this limited use spare tire affects vehicle handling. Since it is not the same tire, replace (or repair) the original tire and reinstall on vehicle at the first opportunity.

194 STARTING AND OPERATING

WARNING!

WARNING!

The limited use spare tires are for emergency use only. Installation of this limited use spare tire affects vehicle handling. With this tire, do not drive more than 60 mph (100 km/h). Keep inflated to the cold tire inflation pressure listed on either your tire placard or limited use spare tire and wheel assembly. Replace (or repair) the original tire at the first opportunity and reinstall it on your vehicle. Failure to do so could result in loss of vehicle control.

Tire Spinning When stuck in mud, sand, snow, or ice conditions, do not spin your vehicle’s wheels above 35 mph (55 km/h). See the paragraph on Freeing A Stuck Vehicle in Section 6 of this manual.

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 don’t let anyone near a spinning wheel, no matter what the speed.

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

STARTING AND OPERATING 195

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.

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.

196 STARTING AND OPERATING

WARNING!

• Do not use a tire, wheel size or rating other than that specified for your vehicle. Some combinations of unapproved tires and wheels may change sus- pension dimensions and performance characteris- tics, resulting in changes to steering, handling, and braking of your vehicle. This can cause unpredict- able 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.

CAUTION!

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

Alignment And Balance Poor suspension alignment may result in: • Fast tire wear. • Uneven tire wear, such as feathering and one-sided • Vehicle pull to right or left. Tires may also cause the vehicle to pull to the left or right. Alignment will not correct this condition. See your dealer for proper diagnosis.

wear.

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.

SUPPLEMENTAL TIRE PRESSURE INFORMATION A light load vehicle condition is defined as two passen- gers {150 lbs (68 kg) each} plus 200 lbs (91kg) of cargo. Cold tire inflation pressures for a lightly loaded vehicle will be found on a “Supplemental Tire Pressure Inflation” label located on the face of the driver’s door or in the Tire Information Pressures pamphlet in the glove box.

STARTING AND OPERATING 197

TIRE CHAINS Use “Class S” chains on SRT–10 models, or other traction aids that meet SAE Type “S” specifications. Tire chain use is permitted only on the rear tires of SRT–10 models. NOTE: Chains must be the proper size for the vehicle, as recommended by the chain manufacturer.

198 STARTING AND OPERATING

CAUTION!

To avoid damage to your vehicle, tires or chains, observe the following precautions:

• Because of limited chain clearance between tires and other

of installation, operating speed, and conditions for usage. Always use the lower suggested operating speed of the chain manufacturer if different than the speed recommended by the manufacturer.

These cautions apply to all chain traction devices, includ- ing link and cable (radial) chains. Tire chain use is permitted only on the rear tires of SRT–10 Models. NOTE: The use of class “S” chains is permitted on SRT– 10 Models with the use of 17 x 8 steel wheels (part number 52113265AC) available from your authorized dealer.

CAUTION!

Do not use tire chains on the front wheels. There may not be adequate clearance for the chains and you are risking structural or body damage to your vehicle.

SNOW TIRES Snow tires should be of the same size and type construc- tion as the front tires. Consult the manufacturer of the snow tire to determine any maximum vehicle speed requirement associated with the tire. These tires should always be operated at the vehicle maximum capacity inflation pressures under any load condition. While studded tires improve performance on ice, skid and traction capability on wet or dry surfaces may be poorer than that of non-studded tires. Some states pro- hibit studded tires; local laws should be checked before using these tire types.

TIRE ROTATION RECOMMENDATIONS Tires on the front and rear axles of vehicles operate at different loads and perform different steering, driving, 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.

200 STARTING AND OPERATING

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.

NOTE: On Canadian vehicles only, if your Ram truck is equipped with All-Season type tires on the front and ON/OFF Road type tires mounted on the rear, do not use a front to back rotation pattern. Instead, rotate your tires side to side at the recommended intervals.

FUEL REQUIREMENTS

Your vehicle is designed to meet all emis- sion regulations and provide excellent fuel economy when using high quality pre- mium unleaded gasoline having an octane rating of 91 or higher.

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 automobile manufacturers around the world have issued and endorsed consistent gasoline specifica- tions (the World Wide Fuel Charter, WWFC) to define fuel properties necessary to deliver enhanced emissions, engine performance, and durability for your vehicle. The manufacturer recommends the use of gasolines that meet the WWFC specifications if they are available. Reformulated Gasoline Many areas of the country require the use of cleaner burning fuel referred to as Reformulated Gasoline. Reformulated gasolines contain oxygenates, and are spe- cially blended to reduce vehicle emissions and improve air quality.

STARTING AND OPERATING 201

The manufacturer strongly supports the use of reformu- lated gasolines. Properly blended reformulated gasolines will provide excellent performance and durability of engine and fuel system components. Gasoline/Oxygenate Blends Some fuel suppliers blend unleaded gasoline with mate- rials called oxygenates such as 10% alcohol, MTBE, ETBE or TAME. Oxygenates are required in some areas of the country during the winter months to reduce carbon monoxide emissions. Fuels blended with these oxygen- ates may be used in your vehicle.

CAUTION!

DO NOT use gasolines containing METHANOL. Gasoline containing methanol may damage critical fuel system components.

202 STARTING AND OPERATING

MMT In Gasoline MMT is a manganese containing metallic additive that is blended into some gasoline to increase the octane. Gaso- lines blended with MMT offer no performance advantage beyond gasolines of the same octane number without MMT. Gasolines blended with MMT reduce spark plug life and reduce emission system performance in some vehicles. The manufacturer recommends that gasolines without MMT be used in your vehicle. The MMT content of gasoline may not be indicated on the gasoline pump, therefore, you should ask your gasoline retailer whether or not his/her gasoline contains MMT. It is even more important to look for gasolines without MMT in Canada because MMT can be used at higher levels than are allowed in the United States. MMT is prohibited in Federal and California reformulated gaso- lines.

Sulfur In Gasoline Your vehicle may have been designed to meet California low emission standards on clean burning, low sulfur, California gasoline. Gasoline sold outside of California is allowed to have higher sulfur levels that may affect the performance of your vehicle’s catalytic converter. This may cause the Malfunction Indicator Light or Service Engine Soon Light to illuminate. The illumination of this light while operating on high sulfur gasoline does not necessarily mean your emission system control system is malfunctioning. The manufac- turer recommends that you try a different brand of unleaded gasoline having lower sulfur to determine if the problem is fuel related before returning your vehicle to an authorized dealer for service. If the Malfunction Indicator light or Service NOTE: Engine Soon light is flashing, immediate service is re- quired.

Materials Added to Fuel All gasoline sold in the United States and Canada is required to contain effective detergent additives. The use of additional detergents or other additives is not needed under normal conditions. 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

STARTING AND OPERATING 203

some light smoke, your engine may be out of tune or malfunctioning and may require immediate service. Contact your dealer for service assistance. • When pulling a heavy load or driving a fully loaded vehicle when the humidity is low and the temperature is high, use a premium unleaded fuel to help prevent spark knock. If spark knock persists, lighten the load, or engine piston damage may result. • The use of fuel additives which are now being sold as octane enhancers is not recommended. Many of these products contain high concentrations of methanol. Fuel system damage or vehicle performance problems may result from the use of such fuels or additives and is not the responsibility of the manufacturer.

NOTE: systems can result against you.

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.

ADDING FUEL

NOTE: The fuel tank filler tube is about 2 inches (50
mm) down from the opening. If fuel is poured from a portable container, the container should have a flexible nozzle long enough to extend into the fuel filler tube.

CAUTION!

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.

STARTING AND OPERATING 205

NOTE: Tighten the gas cap until you hear a “clicking” sound. This is an indication that the gas cap is properly tightened. Make sure that the gas cap is tightened each time the vehicle is refueled.

Fuel Filler Cap (Gas Cap)

The gas cap is behind the fuel filler door. If the gas cap is lost or damaged, be sure the replacement cap is for use with this vehicle.

WARNING!

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

CAUTION!

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

206 STARTING AND OPERATING

WARNING!

• Remove the fuel tank filler tube cap (gas cap) slowly to prevent fuel spray from the filler neck which may cause injury. • The volatility of some gasolines may cause a buildup of pressure in the fuel tank that may increase while you drive. This pressure can result in a spray of gasoline and/or vapors when the cap is removed from a hot vehicle. Removing the cap slowly allows the pressure to vent and prevents fuel spray. • Never allow any lit smoking materials near the vehicles while removing the cap or filling the tank. • Never add fuel to the vehicle when the engine is

running.

CATALYTIC CONVERTER The catalytic converter requires the use of unleaded fuel only. Leaded gasoline will destroy the effectiveness of the catalyst as an emission control device. Under normal operating conditions, the catalytic converter will not require maintenance. However, you must keep the en- gine maintained to assure proper operation and prevent possible damage. NOTE: systems can result against you.

Intentional tampering with emissions control in civil penalties being assessed

CAUTION!

Damage to the catalytic converter can result if your vehicle is not kept in proper operating condition. In the event of engine malfunction, particularly involv- ing engine misfire or other apparent loss of perfor- mance, have your vehicle serviced promptly. Contin- ued operation of your vehicle with a severe malfunction could cause the converter to overheat, resulting in possible damage to the converter and vehicle.

As with any vehicle, do not park or operate this vehicle in areas where combustible materials such as grass or leaves can come in contact with a hot exhaust system. A scorching odor may be detected if you continue to run a malfunctioning engine. The odor may indicate severe and abnormal catalyst overheating. If this occurs, the

STARTING AND OPERATING 207

vehicle should be stopped, the engine shut off and the vehicle allowed to cool. Service, including a tune-up to manufacturer’s specifications should be obtained imme- diately. To minimize the possibility of catalyst damage: • Do not try to start the engine by pushing or towing the • Do not idle the engine with any spark plug wires • Do not idle the engine for prolonged periods during very rough idle or malfunctioning operating condi- tions.

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 and cargo. The label also specifies maximum 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 This is the minimum allowable tire size for 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. 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.

STARTING AND OPERATING 209

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 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.

NOTE: The weights shown in this chart are not necessarily the weights for your vehicle. Also, the amount of load added to both the front and rear axles can be computed after the vehicle has been weighed both in its ⴖcurb weightⴖ condition, and in its ⴖloaded and ready for operationⴖ condition.

210 STARTING AND OPERATING

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.

An EXAMPLE of a loaded vehicle is shown in the following chart. Note that neither GVWR nor GAWR capabilities are exceeded. Overloading can cause poten- tial safety hazards and shorten service life.

TRAILER TOWING All Dodge Ram Pickup trucks are intended to tow trailers up to 2,000 lbs (907 kg) without added equipment or alterations to standard equipment. Your vehicle may be factory equipped for safe towing of trailers weighing over 2,000 lbs (907 kg) with the optional Trailer Tow Prep Package. See your Dodge dealer for package content. Definitions The following trailer towing related terminology defini- tions will assist in understanding the subsequent sec- tions: GROSS COMBINATION WEIGHT RATING (GCWR) is the total permissible weight of your vehicle and trailer when weighed in combination. (Note that GCWR ratings include a 150 lb (68 kg) allowance for the presence of a driver.) Tongue Weight (of a trailer) is the weight placed on a vehicle’s trailer hitch by the trailer.

212 STARTING AND OPERATING

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. TRAILER SWAY CONTROL is a telescoping link that can be installed between the hitch receiver and the trailer tongue that typically provides adjustable friction associ- ated with the telescoping motion to dampen any un- wanted trailer swaying motions while traveling.

CAUTION!

• During the first 500 miles (805 km) your new vehicle is driven, do not tow a trailer. Doing so may damage your vehicle. • When first towing a trailer, limit your speed to 50
mph (80 km/h) during the first 500 miles (805 km) of towing.

Consider the following items when computing the weight on the rear axle: • the tongue weight of the trailer • the weight of any other type of cargo or equipment put

in or on your vehicle

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 Certification label located at the driver’s door for the Gross Vehicle Weight Rating.

WARNING!

Improper towing can lead to an injury accident. Follow these guidelines to make your trailer towing as safe as possible:

Perform the maintenance listed in the “Maintenance Schedules” section of this manual (Section 8). When towing a trailer, never exceed the Gross Axle Weight Rating (GAWR), or Gross Combined Vehicle Weight (GCVW).

STARTING AND OPERATING 213

CAUTION!

When hauling cargo or towing a trailer, do not overload your vehicle or trailer. Overloading can cause a loss of control, poor performance or damage to brakes, axle, engine, transmission, steering, sus- pension, body structure or tires.

Axle Lubricant and Trailer Towing

vehicle and trailer.

Trailer Towing Recommendations • All trailer hitches should be professionally installed on • Safety chains must always be used between your • 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. An electrically–actuated electric trailer brake controller is recommended.

• Trailer brakes are recommended for trailers over 1000
lbs (454 kg) and are required for trailers in excess of 2,000 lbs (907 kg) • Use an approved wiring harness connector on the trailer. Standard equipment on all RAM pickup mod- els provides a 4-way trailer tow connector located under the bumper. This connector contains the follow- ing vehicle circuits: park/tail lamps, left stop/turn lamp, right stop/turn lamp, and ground. With the optional Trailer Tow Prep package a 7-way connector is provided with the following additional circuits: backup lamp, trailer battery and electric brake.

NOTE: Connect trailer lighting and brakes using factory harnesses only. Do not cut or splice wiring to the brake circuits.

• Be sure the trailer is loaded heavier in front, with 60% to 65% of the weight in front of the axle(s). 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. (For a ⬙5th Wheel⬙ style trailer, this range of loading on the ⬙King Pin⬙ should be between 15% and 25%.) • Make certain that the load is secured in the trailer and will not shift during travel. When towing cargo such as livestock, dynamic load shifts can occur that require the driver to maintain attention.

STARTING AND OPERATING 215

Trailer Towing — Hitches With a Class I Hitch, your vehicle can be equipped to tow trailers with a Gross Trailer Weight (GTW) of 2,000 lbs (907 kg) maximum. With a Class II Hitch, your vehicle can be equipped to tow trailers with a Gross Trailer Weight (GTW) of 3,500
lbs (1 587 kg ) maximum. Tongue weight must be equal to at least 10% of GTW, but no more than 15% of GTW. With a Class III Hitch, your vehicle can be equipped to tow trailers with a Gross Trailer Weight (GTW) of 5,000
lbs (2 268 kg) maximum. Factory-installed rear step bumpers are rated a Class III hitch. A frame mounted hitch of up to Class IV rating, as rated by the hitch manufacturer, may also be installed. With a Class IV Hitch, you can tow a trailer with a Gross Trailer Weight of up to 12,000 lbs (5 443 kg) maximum depend- ing on your vehicle equipment.

216 STARTING AND OPERATING

Connecting Trailer Lighting And Electric Trailer Brakes

NOTE: A 4-way trailer tow connector, located behind the bumper, is standard equipment on all Ram pickup models. This connector contains the following vehicle circuits: park/tail lamps, left stop/turn lamp, right stop/ turn lamp, and ground. With the optional Trailer Tow Prep package a 7-way connector is also provided with the following additional circuits: backup lamp, trailer battery and electric brake. NOTE: There is also a 4–way connector located under the instrument panel, located to the left of the brake pedal that is used for the electric brake. This connector contains the following vehicle circuits; power ground, battery, stop lamp switch and electric brake feed. The 4–way is optional with the trailer tow prep package.

CAUTION!

Adding lights or electrical devices to the headlamp/ park lamp circuit can be accomplished by connecting to the standard 4-way trailer tow connector located behind the rear bumper. The maximum current ca- pacity for the park lamp circuit should not exceed 15
amps total (a typical park lamp bulb can draw from 0.5 to 1.0 amperes of current). No connections can be made to the headlamp switch itself, because it is not designed for high current applications. Connections to the headlamp switch will cause the exterior lights to malfunction.

CAUTION!

Connect trailer lighting and brakes using factory harnesses only. Do not cut or splice wiring to the brake circuits. Use an approved wiring harness con- nector on the trailer.

Trailer Weight and Trailer Tongue Weight Gross Trailer Weight (GTW) means the weight of the trailer plus the weight of all cargo, consumables and equipment loaded on the trailer when in actual under- way towing condition. The recommended way to mea- sure GTW is to put your fully loaded trailer on a vehicle scale. The entire weight of the trailer must be supported by the scale. Tongue Weight is the weight placed on the vehicle’s trailer hitch by the trailer. Always load a trailer with 60%

STARTING AND OPERATING 217

to 65% of the weight in the front of the trailer. This places 10% to 15% of the GTW on the tow hitch of your vehicle. Trailer sway control and equalizing hitch are required for Class III or IV trailer hitches and tongue weights above 350 lbs (159 kg).

Tongue weight must be equal to at least 10% of GTW, but no more than 15% of GTW.

218 STARTING AND OPERATING

Also, there are maximum tongue weight ratings that are not to be exceeded, as follows: • Class III (the bumper ball type) 500 lbs (227 kg) • Class IV (the receiver hitch type) 1200 lbs (544 kg) NOTE: When towing a trailer, the following require- ments must be adhered to: • GCWR must not be exceeded • Total weight must be distributed between the tow vehicle and the trailer such that the following four (4) ratings are not exceeded: 1. GVWR 2. GTW 3. 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 [15% to 25% for a ⴖ5th Wheelⴖ style trailer] as a percentage of total trailer weight.)

Rotate the wheel wrench handle coun- terclockwise until the spare tire is on the ground with enough cable slack to allow you to pull it out from under the vehicle. When the spare is clear, tilt the retainer at the end of the cable and pull it through the center of the wheel.

WHAT TO DO IN EMERGENCIES 231

It is recommended that you stow the flat or spare to avoid tangling the loose cable. NOTE: The winch mechanism is designed for use with the jack extension tube only. Use of an air wrench or other power tools is not recommended and can damage the winch.

Tire Changing Procedure

WARNING!

Getting under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You could be crushed. Never get any part of your body under a vehicle that is on a jack. Never start or run the engine while the vehicle is on a jack. If you need to get under a raised vehicle, take it to a service center where it can be raised on a lift.

Do not raise this vehicle using a bumper jack. The jack is designed as a tool for changing tires on this vehicle only. It is not recommended that the jack be used for service purposes or to lift more than one wheel at a time. Preparations Park the vehicle on a firm level surface, avoiding ice or slippery areas. Set the parking brake and place the gear selector in REVERSE (manual transmission).

WARNING!

Do not attempt to change a tire on the side of the vehicle close to moving traffic. Pull far enough off the road to avoid the danger of being hit when operating the jack or changing the wheel. • Turn on the Hazard Warning Flasher.

• Block both the front and rear of the wheel diagonally oppo- site the jacking position. For example, front wheel is being changed, block the left rear wheel. • Passengers should not remain in the vehicle when the

3. Placement of the Jack: • When changing a front wheel, place the scissors jack under the rear portion of the lower control arm as shown below.

• When changing a rear wheel, assemble the jack drive tube to the jack and connect the drive tube to the extension tube. Place the jack under the axle between the spring and the shock absorber with the drive tubes extending to the rear.

• Operate the jack using the jack drive tube and the wheel wrench. The tube extension, may be used, but is not required.

• Connect the jack tube extension and wheel wrench.

WHAT TO DO IN EMERGENCIES 235

Before raising the wheel off the ground, make sure that the jack will not damage surrounding truck parts and adjust the jack position as required.

4. By rotating the wheel wrench clockwise, raise the vehicle until the wheel just clears the surface.

6. Using the wheel wrench, finish tightening the nuts using a crisscross pattern. Correct nut tightness is 90–110
ft. lbs. (125–150 N·m). If in doubt about the correct tightness, have them checked with a torque wrench by your dealer or at a service station.

WARNING!

Raising the vehicle higher than necessary can make the vehicle unstable and cause an accident. It could slip off the jack and hurt someone near it. Raise the vehicle only enough to remove the tire.

5. Remove the wheel nuts and pull the wheel off. Install the spare wheel and wheel nuts. Lightly tighten the nuts. To avoid risk of forcing the vehicle off the jack, do not fully tighten the nuts until the vehicle has been lowered.

WARNING!

A loose tire or jack thrown forward in a collision or hard stop could injure someone in the vehicle. Always stow the jack parts and the extra tire and wheel in the places provided.

7. Remove wheel blocks. Do not install chrome or alu- minum wheel center caps on the spare wheel. This may result in cap damage. 8. Lower the jack to its fully closed position. Stow the replaced tire, jack, and tools as previously described.

236 WHAT TO DO IN EMERGENCIES

9. Adjust the tire pressure when possible. NOTE: Do not oil wheel studs. For chrome wheels, do not substitute with chrome plated wheel nuts. Wheel Nuts All wheel nuts should be tightened occasionally to elimi- nate the possibility of wheel studs being sheared or the bolt holes in the wheels becoming elongated. This is especially important during the first few hundred miles of operation to allow the wheel nuts to become properly set. All nuts should first be firmly seated against the wheel. The nuts should then be tightened to recom- mended torque. Tighten the nuts to final torque in increments. Progress around the bolt circle, tightening the nut opposite to the nut just previously tightened until final torque is achieved. Recommended torques are shown in the following chart.

Torque Newton Meters 125-150

Disc Wheels

To Stow The Flat Or Spare Turn the wheel so that the valve stem is down. Slide the wheel retainer through the center of the wheel and position it properly across the wheel opening. For convenience in checking the spare tire inflation, stow with the valve stem toward the rear of the vehicle. Attach the wheel wrench to the extension tube. Rotate the winch mechanism until the wheel is drawn into place against the underside of the vehicle. Continue to rotate until you feel the winch mechanism slip or click 3 or 4
times. It cannot be overtightened. Push against the tire several times to be sure it is firmly in place.

HOISTING A conventional floor jack may be used at the jacking locations, refer to the graphics that show jacking loca- tions. However, a floor jack or frame hoist must never be used on any other parts or the underbody.

CAUTION!

Never use a floor jack directly under the differential housing of a loaded truck or damage to your vehicle may result.

JUMP-STARTING You should not try to start your vehicle by pushing or towing. Pushing or towing a vehicle equipped with a manual transmission may overheat and damage the catalytic converter. Also, there is a greater risk of an accident when a vehicle is being pushed or towed. If the vehicle has a discharged battery, booster cables may be used to obtain a start from a booster battery or the battery in another vehicle. This type of start can be dangerous if done improperly, so follow this procedure carefully.

238 WHAT TO DO IN EMERGENCIES

WARNING!

Battery fluid is a corrosive acid solution; do not allow battery fluid to contact eyes, skin or clothing. Don’t lean over battery when attaching clamps or allow the clamps to touch each other. If acid splashes in eyes or on skin, flush contaminated area immedi- ately with large quantities of water. A battery generates hydrogen gas which is flam- mable and explosive. Keep flame or spark away from the vent holes. Do not use a booster battery or any other booster source that has a greater than 12 volt system, i.e. Do not use a 24 volt power source.

Check the Battery Test Indicator (If Equipped). If a yellow or bright colored dot is visible in the indicator (if equipped), DO NOT jump-start the battery.

If the indicator (if equipped) is dark or shows a green dot, proceed as follows: 1. Remove all metal jewelry such as watch bands or bracelets which might make an unintended electrical contact.

2. Park the booster vehicle within cable reach but with- out letting the vehicles touch. Set the parking brake on both vehicles, place transmission in Neutral, and turn the ignition OFF. 3. Turn off the heater, radio, and all unnecessary electri- cal loads. 4. Connect one end of a jumper cable to the positive terminal of the booster battery. Connect the other end of the same cable to the positive terminal of the discharged battery.

WARNING!

Do not permit vehicles to touch each other as this could establish a ground connection and personal injury could result.

WHAT TO DO IN EMERGENCIES 239

240 WHAT TO DO IN EMERGENCIES

5. Connect the other cable, first to the negative terminal of the booster battery and then to the engine of the vehicle with the discharged battery. Make sure you have a good contact on the engine.

WARNING!

• Do not connect the cable to the negative post of the discharge battery. The resulting electrical spark could cause the battery to explode. • During cold weather when temperatures are be- low freezing point, electrolyte in a discharged battery may freeze. Do not attempt jump starting because the battery could rupture or explode. The battery temperature must be brought up above freezing point before attempting jump start.

6. Start the engine in the vehicle which has the booster battery, let the engine idle a few minutes, then start the engine in the vehicle with the discharged battery. 7. When removing the jumper cables, reverse the above sequence exactly. Be careful of the moving belts and fan.

WARNING!

Any procedure other than above could result in: 1. Personal injury caused by electrolyte squirting out the battery vent; 2. Personal injury or property damage due to battery explosion; 3. Damage to charging system of booster vehicle or of immobilized vehicle.

FREEING A STUCK VEHICLE If vehicle becomes stuck in snow, sand, or mud, it can often be moved by a rocking motion. Move the gear selector rhythmically between FIRST and REVERSE, while applying slight pressure to the accelerator. In general, the least amount of accelerator pedal pressure to maintain the rocking motion without spinning the wheels or racing the engine is most effective. Racing the engine or spinning the wheels, due to the frustration of not freeing the vehicle, may lead to transmission over- heating and failure. Allow the engine to idle with the transmission selector in NEUTRAL for at least one minute after every five rocking-motion cycles. This will minimize overheating and reduce the risk of transmis- sion failure during prolonged efforts to free a stuck vehicle.

WHAT TO DO IN EMERGENCIES 241

TOWING A DISABLED VEHICLE Proper towing or lifting equipment is required to prevent damage to your vehicle. Use only tow bars and other equipment designed for the purpose, following equip- ment manufacturer’s instructions. Use of safety chains is mandatory. Attach a tow bar or other towing device to the main structural members of the vehicle—not to bumpers or associated brackets. State and local laws applying to vehicles under tow must be observed. Provided that the transmission is operable, tow with the transmission in Neutral and the ignition key in the OFF position along with the front wheels raised and the rear wheels on the ground. Speed must not exceed 30 mph (50
km/h) and distance must not exceed 15 miles (25 km). If the vehicle is to be towed more than 15 miles (25 km) the vehicle must be towed with the rear wheels raised and the front wheels on the ground. It may also be towed on a flatbed or with the front wheels raised and the rear wheels on a dolly.

ONBOARD DIAGNOSTIC SYSTEM (OBD II) Your vehicle is equipped with a sophisticated onboard diagnostic system called OBD II. This system monitors the performance of the emissions and engine control systems. When these systems are operating properly, your vehicle will provide excellent performance and fuel economy, as well as engine emissions well within current government regulations. If any of these systems require service, the OBD II system will turn on the “Malfunction Indicator Light.” It will
