CLIMATE CONTROLS

Automatic Temperature Control The Infrared Dual-Zone Climate Control System auto- matically maintains the interior comfort level desired by the driver and passenger. This is accomplished by a dual sun-sensor in the top of the instrument panel, and an infrared sensor located in the face of the control unit. There are also various sensors monitored by this system which take account for vehicle speed, A/C pressure, outside temperature, and engine cooling temperature. The infrared sensor independently measures the surface temperature of the driver and passenger. Based on the sensor input, the system automatically adjusts the air flow temperature, the air flow volume, and amount of outside air recirculation. This maintains a comfortable temperature even under changing conditions.

Automatic Temperature Controls

NOTE: The numbers on the temperature dial represent a comfort setting when the Mode knob is set to Auto, and not the actual air temperature. Operation of the system is quite simple. Begin by turning the right mode knob to AUTO, and place the blower control (left knob) to either LO AUTO or HI AUTO. The

LO AUTO position should be used for front seat occu- pants only. The HI AUTO position should be used when more air flow is desired, or when rear seat occupants are present. Dial in the comfort setting you would like the system to maintain by rotating the driver’s or passenger’s control knob. Once the comfort level is selected the system will maintain that level automatically using the heating system. Should the desired comfort level require air conditioning, the system will automatically make the adjustment. You will experience the greatest efficiency by simply allowing the system to function automatically. Selecting the OFF position on the fan control stops the system completely. NOTE: The temperature setting can be adjusted at any time without affecting automatic control operation. How- ever, if the driver and/or passenger temperature knobs are set to the full hot or full cold positions, the air

UNDERSTANDING YOUR INSTRUMENT PANEL 223

temperature out of the ducts will be full hot or full cold respectively. With the temperature setting in these posi- tions, the system does not attempt automatic comfort control.

The air conditioning in this system is automatic. Pressing this button while in AUTO mode will cause the LED to flash three times and remain off. This indicates that the system is in AUTO and requesting the air conditioning is not necessary.

The system will automatically control recircu- lation. However, pressing this button will tem- porarily put the system in recirculation mode. This can be used when outside conditions such as smoke, odors, dust, or high humidity are present. This will cause the LED to illuminate.

224 UNDERSTANDING YOUR INSTRUMENT PANEL

NOTE: • The surface of the climate control panel, and the top center of the instrument panel should be kept free of debris due to the climate control sensor’s location. Mud on the windshield may also cause poor operation of this system. • To provide you with maximum comfort in the auto- matic mode, during cold start-ups the blower fan will remain off until the engine warms up. However, the fan will engage immediately if the defrost mode is selected or if you manually select a blower speed. • Under certain conditions (after the vehicle is turned off) the climate control system may recalibrate and a noise may be heard for 20 seconds. This is part of normal operation. • Most of the time, when in Automatic operation, you can temporarily put the system into recirculation mode by pressing the Recirc button. However, under

certain conditions in automatic the system is blowing air out of the defrost vents. When these conditions are present and the Recirc button is pressed the indicator will flash and remain off. This tells you that you are unable to go into recirculation mode at this time. If you would like to go to Recirculation mode, you must first move your mode knob to panel, panel/floor or floor, then hit the Recirc button. This feature will reduce the possibility of window fogging.

Manual Operation This system offers a full complement of manual override features which consist of Blower Preferred Automatic, Mode Preferred Automatic with Manual Air Temperature Control and Manual. This means the customer can over- ride the blower, mode and disable automatic temperature control completely. NOTE: Please read the Automatic Temperature Control Operation Chart below for details.

UNDERSTANDING YOUR INSTRUMENT PANEL 225

226 UNDERSTANDING YOUR INSTRUMENT PANEL

NOTE: Regardless of the type of operation, when a temperature knob is set to the full clockwise or full counterclockwise position, the system will deliver full hot or full cold air out of the ducts, respectively. The operator can override the AUTO mode setting and select the direction of the air by rotating the right mode knob to one of the following positions. When the Mode is set to any position other than AUTO, the automatic control of air temperature is disabled. The user must adjust the temperature knobs to obtain the desired tem- perature. • Defrost

Air is directed to the windshield through the outlets at the base of the windshield. Air is also directed to the front door windows through the side window demister grilles. Some airflow is delivered to the floor while in defrost so that comfort can be maintained.

NOTE: The defrost mode is not automatically selected. It must be manually selected, when desired. • Defrost/Floor

Air flows through the front and rear floor outlets and the outlets at the base of the windshield. Air is also directed to the front door windows through the side window demister grilles. Some air- flow is delivered to the floor while in defrost so that comfort can be maintained.

• Floor

• Bi-Level

Air flows through the floor outlets located under the instrument panel and into the rear seating area through vents under the front seats. Some airflow is delivered to defrost while in floor mode, so that comfort can be maintained.

Air flows both through the outlets located in the instrument panel and those located on the floor.

Air flows through the registers in the back of the center console, and under the front seats to the rear seat passengers. These registers can be closed to block airflow. The center console outlets deliver conditioned air while the floor outlets deliver heated air.

• Panel

Air flows through the outlets located in the in- strument panel. Air flows through the registers in the back of the center console to the rear seat passen- gers. These registers can be closed to block airflow.

Depress this button to turn on and off the air conditioning during manual operation only. Con- ditioned outside air is then directed through the outlets selected on the mode control dial. The button includes an LED that illuminates when manual operation is selected. NOTE: To manually control the air conditioning the mode selector must be moved out of the AUTO position.

and the heated side mirrors

Press this button to turn on the rear window defroster (if equipped). An LED in the button will illuminate indicat- ing that the rear window defroster is ON. The defroster automatically turns off after approximately 10 minutes of operation for the first push of the button, and will turn off after approximately 5 minutes for the second push of the button.

CAUTION!

To avoid damaging the electrical conductors of the rear window defroster, do not use scrapers, sharp instruments, or abrasive window cleaners on the interior surface of the window. Labels can be peeled off after soaking with warm water.

228 UNDERSTANDING YOUR INSTRUMENT PANEL

This button can be used to block out smoke, odors, dust, high humidity, or if rapid cooling is desired. The recirculation mode should only be used temporarily. The button includes an LED that illuminates, which indicates that the recircula- tion mode is active. You may use this feature separately. NOTE: Extended use of recirculation may cause the windows to fog. If the interior of the windows begins to fog, press the “Recirculate” icon button to return to outside air. Some temp./humidity conditions will cause captured interior air to condense on windows and ham- per visibility. For this reason, the system will not allow “Recirculate” to be selected while in the defrost or defrost/floor modes. Attempting to use the recirculation while in these modes will cause the LED in the button to blink and then turn off.

Summer Operation The engine cooling system in air conditioned vehicles must be protected with a high-quality antifreeze coolant to provide proper corrosion protection and to protect against engine overheating. A 50% solution of ethylene glycol antifreeze coolant in water is recommended. Refer to “Maintenance Procedures” in Section 7 of this manual for proper coolant selection. Winter Operation Use of the air Recirculation mode during winter months is not recommended because it may cause window fogging. NOTE: Refer to the “Operating Tips” chart (for Manual A/C Control) in this section for suggested control set- tings in different weather conditions.

UNDERSTANDING YOUR INSTRUMENT PANEL 229

Outside Air Intake Make sure the air intake, located directly in front of the windshield, is free of obstructions such as leaves. Leaves collected in the air intake may reduce airflow and if they enter the plenum they could plug the water drains. In winter months make sure the air intake is clear of ice, slush and snow.

Vacation Storage Anytime you store your vehicle, or keep it out of service (i.e. vacation) for two weeks or more, run the air condi- tioning system at idle for about five minutes in the fresh air and high blower setting. This will insure adequate system lubrication to minimize the possibility of com- pressor damage when the system is started again. Window Fogging Interior fogging on the windshield can be quickly re- moved by turning the mode selector to Defrost, and turning on the high blower. The Defrost/Floor mode can be used to maintain a clear windshield and provide sufficient heating. If side window fogging becomes a problem increase blower speed. Vehicle windows tend to fog on the inside in mild but rainy or humid weather. NOTE: Recirculate without A/C should not be used for long periods as fogging may occur.

STARTING PROCEDURES Before starting your vehicle, adjust your seat, adjust both inside and outside mirrors, and fasten your seat belts.

WARNING!

Do not leave children or animals inside parked vehicles in hot weather. Interior heat build up may cause serious injury or death.

The gear selector must be in the N (Neutral) or P (Park) position before you can start the engine. Apply the brakes before shifting to any driving gear. Normal Starting Normal starting of either a cold or a warm engine is obtained without pumping or depressing the accelerator pedal. Turn the key to the START position and release when the engine starts. If the engine fails to start within

10 seconds, turn the key to the OFF position, wait 5
seconds, then repeat the normal starting procedure.

Ignition Key Positions

WARNING!

Never pour fuel or other flammable liquids into the throttle body air inlet opening in an attempt to start the vehicle. This could result in a flash fire causing serious personal injury.

Extreme Cold Weather (below –20°F (–29°C) To insure reliable starting at these temperatures, use of an externally powered electric engine block heater (available from your authorized dealer) is recommended. If Engine Fails to Start If the engine fails to start after you have followed the “Normal Starting” or “Extreme Cold Weather” proce- dures, it may be flooded. Push the accelerator pedal all the way to the floor and hold it there while cranking the engine. This should clear any excess fuel in case the engine is flooded.

STARTING AND OPERATING 235

NOTE: To prevent damage to the starter, do not crank the engine for more than 15 seconds at a time. Wait 10 to 15 seconds before trying again. If the engine has been flooded, it may start to run, but not have enough power to continue running when the key is released. If this occurs, continue cranking with the accel- erator pedal pushed all the way to the floor. Release the accelerator pedal and the key once the engine is running smoothly. If the engine shows no sign of starting after two 15– second periods of cranking with the accelerator pedal held to the floor, the “Normal Starting” or “Extreme Cold Weather” procedures should be repeated.

236 STARTING AND OPERATING

After Starting The idle speed will automatically decrease as the engine warms up.

vehicle, may be somewhat abrupt. This is a normal condition, and precision shifts will develop within a few hundred miles.

CAUTION!

Long periods of engine idling, especially at high engine speeds can cause excessive exhaust tempera- tures which can damage your vehicle. Do not leave your vehicle unattended with the engine running.

TRANSMISSION SHIFTING

5–Speed Automatic Transmission The electronically controlled transmission provides a precise shift schedule. The transmission electronics are self-calibrating; therefore, the first few shifts on a new

Automatic Shift Controls

WARNING!

Gear Ranges

STARTING AND OPERATING 237

It is dangerous to shift the selector lever out of P (Park) or N (Neutral) 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 reverse. 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 foot is firmly on the brake pedal.

Brake Transmission Shift Interlock System This vehicle is equipped with a brake transmission shift interlock system (BTSI) that holds the gearshift lever in the P (Park) position when the ignition switch is in the LOCK position. To move the gear selector lever out of the P (Park) position, the ignition switch must be turned to the ON position, and the brake pedal must be depressed.

NOTE: After selecting any gear range, wait a moment to allow the selected gear to engage before accelerating. This is especially important when the engine is cold. If there is a need to restart the engine be sure to cycle the key to the LOCK position before restarting. Transmission gear engagement may be delayed after restarting the engine if the key is not cycled to the LOCK position first. P (Park) Supplements the parking brake by locking the transmis- sion. The engine can be started in this range. Never use P (Park) while the vehicle is in motion. Apply the parking brake when leaving the vehicle in this range.

238 STARTING AND OPERATING

WARNING!

Unintended movement of a vehicle could injure those in and near the vehicle. As with all vehicles, you should never exit a vehicle while the engine is running. Before exiting a vehicle, you should apply the park brake, shift the transmission into P (Park), and remove the key from the ignition. Once the key is removed from the ignition the transmission shift lever is locked in the P (Park) position, securing the vehicle against unwanted movement. Furthermore, you should never leave children unattended inside a vehicle.

R (Reverse) Shift into this range only after the vehicle has come to a complete stop.

N (Neutral) No power is transmitted from the engine to the drive axle. When the brakes are released, the vehicle can roll freely. Do not engage in N (Neutral) position while driving except to coast when the vehicle is in danger of skidding (e.g., on icy roads). D (Drive) The transmission automatically upshifts through fifth gear. The D (Drive) position provides optimum driving characteristics under all normal operating conditions. For additional shifting information, refer to “Autostick” later in this section. Rocking the Vehicle If the vehicle becomes stuck in snow, sand, or mud, it can often be moved by a rocking motion. Move the gear selector rhythmically between D (Drive) and R (Reverse), while applying slight pressure to the accelerator.

NOTE: The Electronic Stability Program (ESP) and Traction Control (if equipped) should be turned OFF before attempting to rock the vehicle. Refer to “Electronic Brake Control System” in Section 3 of this manual. The least amount of accelerator pedal pressure to main- tain 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 overheating and failure. Allow the engine to idle with the transmission selector in N (Neutral) for at least one minute after every five rocking-motion cycles. This will minimize overheat- ing and reduce the risk of transmission failure during prolonged efforts to free a stuck vehicle.

STARTING AND OPERATING 239

CAUTION!

When “rocking” a stuck vehicle by moving between “First” and R (Reverse), do not spin the wheels faster than 15 mph (24 km/h), or drivetrain damage may result.

AUTOSTICK Autostick is a driver-interactive transmission that offers manual gear shifting capability to provide the driver with more control. Autostick allows the driver to increase engine braking ability, control upshift and downshift points, and enhance the driving experience. This system can also provide the driver with more control during passing, city driving, mountain driving, trailer towing, and many other situations.

240 STARTING AND OPERATING

Autostick Operation By placing the shift lever in the D (Drive) position the lever can be moved from side to side. This allows the driver to engage the AutoStick mode. Moving the shift lever to the right (+) or the left (-) will engage the Autostick mode. In normal driving mode (Boxed “D” displayed in the PRNDL), moving the shift lever to the right (+) will engage the Autostick mode putting the transmission in the cur- rently engaged gear. Moving the shift lever to the Left (-) will engage the Autostick mode and downshift the trans- mission 1 gear. For example, the transmission is in Normal Mode and is currently operating in 3rd gear, a boxed D is displayed in the PRNDL, a push to the right will engage the Autostick mode in 3rd and a Boxed 3 will be displayed in the PRNDL. A push to the left (-) will engage Autostick mode and downshift to 2nd gear and a Boxed 2 will be displayed in the PRNDL. Once Autostick mode is engaged a move to the Right (+) or left (-) will trigger a upshift (+) or trigger a downshift (-).

In the Autostick mode, the transmission will NOTE: only shift up and down when Left or Right (D-/D+) is manually selected by the driver. The transmission will not honor a downshift command if the downshift would result in a engine overspeed condi- tion. The transmission will always honor a upshift com- mand from 1st to 2nd gear, however 2nd - 3rd, 3rd - 4th, and 4th – 5th upshift commands will not be honored if the vehicle speed is to low to maintain operation in the commanded gear. The transmission will automatically downshift as the vehicle slows to a stop. When in the Autostick mode, as the engine RPM nears the engine maximum speed, an “UPSHIFT” message will appear in the Electronic Vehicle Information Center (EVIC) portion of your instrument cluster. This message appears in order to alert the driver that the engine speed is approaching it’s maximum value and a upshift to the next gear is required. In the event that the driver does not

upshift, the engine control system will limit the engine speed to protect the engine. Refer to “Electronic Vehicle Information Center” in Section 4 of this manual. Shifting into or out of the Autostick mode can be done at any time without taking your foot off the accelerator pedal. When the driver wishes to engage Autostick, simply move the shift lever to the Left or Right (D-/D+) position while in D (Drive). Hold the shift lever to the right for at least one second to disengage Autostick. The transmission will now operate automatically; shifting between the five available gears.

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.

242 STARTING AND OPERATING

NOTE: The instrument cluster “Brake Warning Light” indicates only that the parking brake is applied. It does not indicate the degree of brake application.

Before leaving the vehicle parked on a hill, you must make sure the parking brake is fully applied and place the gear selector in the P (Park) position. Make certain the transfer case is in gear. Failure to do so may cause the vehicle to roll and cause damage or injury. When parking on a hill, it is important to set the parking brake before placing the gear selector in P (Park), other- wise the load on the transmission locking mechanism may make it difficult to move the selector out of P (Park). The parking brake should always be applied when the driver is not in the vehicle.

Parking Brake

WARNING!

• Leaving children unattended in a vehicle 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. • Do not leave children or animals inside parked vehicles in hot weather. Interior heat build up may cause serious injury or death.

STARTING AND OPERATING 243

NOTE: Parking brake adjustment and maintenance should be performed by your authorized dealer.

ANTI-LOCK BRAKE SYSTEM The Anti-Lock Brake System (ABS) is designed to aid the driver in maintaining vehicle control under adverse braking conditions. The system operates with a separate computer 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.

To release the parking brake, pull up slightly, press the center button, then lower the lever completely. Be sure the parking brake is fully disengaged before driving. Failure to do so can lead to brake failure.

WARNING!

Significant over or under inflation of tires can lead to loss of braking effectiveness.

244 STARTING AND OPERATING

The Anti-Lock Brake System conducts a low-speed self- test at about 12 mph (20 km/h). If you have your foot lightly on the brake while this test is occurring you may feel slight pedal movement. The movement can be more apparent on ice and snow. This is normal. The Anti-Lock Brake System pump motor runs during the self-test at 12 mph (20 km/h) and during an ABS stop. The pump motor makes a low humming noise during operation, which is normal.

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!

• The Anti-Lock Brake System (ABS) cannot pre- vent the natural laws of physics from acting on the vehicle, nor can it increase braking or steering efficiency beyond 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.

CAUTION!

The Anti-Lock Brake System is subject to possible detrimental effects of electronic interference caused by improperly installed after-market 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

WARNING!

To use your brakes and accelerator more safely, follow these tips:

STARTING AND OPERATING 245

• Do not “ride” the brakes by resting your foot on the pedal. This could overheat the brakes and result in longer stopping dis- unpredictable braking action, tances, or brake damage. • When descending mountains or hills, repeated brak- ing can cause brake fade with loss of braking control. Avoid repeated heavy braking by downshifting the transmission or locking out overdrive whenever pos- sible. • Engines may idle at higher speeds during warm-up, which could cause rear wheels to spin and result in loss of vehicle control. Be especially careful while driving on slippery roads, in close-quarter maneuver- ing, parking or stopping.

246 STARTING AND OPERATING

• Do not drive too fast for road conditions, especially when roads are wet or slushy. A wedge of water can build up between the tire tread and the road. This hydroplaning action can cause loss of traction, braking ability, and control. • After going through deep water or a car wash, brakes may become wet, resulting in decreased performance and unpredictable braking action. Dry the brakes by gentle, intermittent pedal action while driving at very slow speeds.

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.

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 does 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 period 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!

Prolong operation of the steering system at the end of the steering wheel travel will increase the steering fluid temperature and 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

Tire Placard Location

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 in the “Vehicle Loading” sec- tion 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, refer to the “Vehicle Loading” section of this manual.

STARTING AND OPERATING 253

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.

254 STARTING AND OPERATING

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).

256 STARTING AND OPERATING

WARNING!

WARNING!

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.

Do not exceed 55 mph (88 km/h) if the “Tire Pressure Monitoring Telltale Light” is illuminated. Vehicle handling and braking may be reduced. You could have an accident and be severely or fatally injured.

TIRES — GENERAL INFORMATION

Run Flat Tires This vehicle is equipped with run flat tires. Although the tires are designed with a “run flat” feature that allows the vehicle to be driven about 50 miles (80 km) at 55 mph (88
km/h), immediate service should be obtained.

NOTE: The “run flat” feature eliminates the need for a spare tire or jack. This vehicle is not equipped with either a spare tire or jack.

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:

1. Safety—

WARNING!

STARTING AND OPERATING 257

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 prob- lems. 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.

258 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 259

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.

260 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.

STARTING AND OPERATING 261

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.

262 STARTING AND OPERATING

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

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!

All tires should be replaced after six years, regard- less of the remaining tread. Failure to follow this warning can result in sudden tire failure. You could lose control and have an accident resulting in serious injury.

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.

STARTING AND OPERATING 263

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.

264 STARTING AND OPERATING

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.

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 left or right. Alignment will not correct this problem. See your autho- rized 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.

TIRE PRESSURE MONITOR SYSTEM (TPMS)

Premium System 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. The wheel sensors monitor tire pressure, and status for all four active road tires. It is particularly important, for you to check the NOTE: tire pressure in all of your tires regularly and to maintain the proper pressure.

STARTING AND OPERATING 265

The “Tire Pressure Monitoring Telltale Light” will illuminate in the instrument cluster, and an au- dible chime will be activated when one or more tire pressures is low. The “Tire Pressure Monitoring Telltale Light” will flash on and off for 60 seconds when a system fault is detected. The flash cycle will repeat every ten minutes or until the fault condition is removed and reset. The Tire Pressure Monitoring System (TPMS) consists of the following components: • Receiver Module • 4 Wheel Sensors • 3 Wheel Sensor Trigger Modules • Tire Pressure Monitoring System Display Messages in • Tire Pressure Monitoring Telltale Light

the EVIC

266 STARTING AND OPERATING

The system consists of tire pressure monitoring sensors attached to each wheel through the valve stem mounting hole, a central receiver module, Wheel Sensor Trigger Modules mounted in three of the four wheel wells, various Tire Pressure Monitoring System Display Mes- sages in the EVIC, and a “Tire Pressure Monitoring Telltale Light.” NOTE: For vehicles with optional wheel/tire sizes and significantly different tire placard pressures, the placard pressure value and the low-pressure threshold value is re-programmable at your authorized dealer to accommo- date the customer selected wheel/tire combinations rec- ommended by DaimlerChrysler Corporation. The following ⬙warnings⬙ will cause a text message to be displayed, an audible chime to sound, and the “Tire Pressure Monitoring Telltale Light” to illuminate. The audible chime will occur once every ignition cycle for each ⬙warning⬙ detected. The “Tire Pressure Monitoring

Telltale Light” will illuminate continuously (solid) and shall remain illuminated until the warning condition is removed/reset. When the appropriate conditions exist, the Electronic Vehicle Information Center (EVIC) displays the following messages. LEFT FRONT, LEFT REAR, RIGHT FRONT, RIGHT REAR LOW PRESSURE One or more of these messages will be displayed in the EVIC if a low tire pressure condition exists in one or more tires. Inspect all tires for proper inflation pressure, once the proper tire pressure has been set, the TPMS will reset automatically when the vehicle has been driven for at least 2 minutes at or above 15 mph (24 km/h).

CHECK TPM SYSTEM See your authorized dealer when this message appears in the EVIC. This message indicates that a system fault condition has been detected.

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.

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.

Spark Knock 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 “premium” gasoline before 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 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.

STARTING AND OPERATING 269

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. Use of these blends may result in starting and driveability problems and may damage critical fuel system com- ponents.

Problems that result from using methanol/gasoline blends are not the responsibility of the manufacturer. While MTBE is an oxygenate made from Methanol, it does not have the negative effects of Methanol.

270 STARTING AND OPERATING

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 gasolines without MMT in Canada, because MMT can be used at levels higher than those 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, or 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. • The use of fuel additives which are now being sold as octane enhancers are 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 are 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.

272 STARTING AND OPERATING

• 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 trunk closed when driving your vehicle to prevent carbon monoxide and other poisonous ex- haust gases from entering the vehicle.

FUEL TANK FILLER CAP (GAS CAP) The fuel cap is located on the left side of the vehicle. If the fuel cap is lost or damaged, be sure the replacement cap is for use with this vehicle.

Fuel Filler Cap Location

STARTING AND OPERATING 273

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. • Turn the engine off. • Rotate the fuel cap to the left to remove. • To replace the cap, insert it into the filler neck and tighten the cap about 1/4 turn until you hear one click. This is an indication that the cap is properly tightened. • Make sure that the fuel cap tether strap is not caught

under the fuel cap.

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. Loose Fuel Filler Cap Message If the vehicle diagnostic system determines that the fuel filler cap is loose, improperly installed, or damaged, a “CHECK GAS CAP” 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 properly and press the odometer reset button to turn the message off. If the problem continues, the message will appear the next time the vehicle is started. Refer to “Onboard Diagnostic System — OBDII” in Section 7 of this manual for more information.

274 STARTING AND OPERATING

WARNING!

• Remove the fuel cap (gas cap) slowly to prevent fuel spray from the filler neck which may cause injury. • The volatility of some gasoline 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 have any smoking materials lit in or near the vehicle when the fuel cap is removed or the tank filled. • Never add fuel to the vehicle when the engine is

running.

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.

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.

STARTING AND OPERATING 275

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). 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.

276 STARTING AND OPERATING

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. 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 hitch includes a receiver attached to the tow vehicle, plus a removable hitch head and spring bar assembly that fits into the receiver opening and hook up brackets that connect the spring bars to the trailer frame.

Trailer Hitch Classification 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 dealer for package content. The following chart provides the industry standard for the maximum trailer weight a given trailer hitch class can tow and should be used to assist you in selecting the correct trailer hitch for your intended towing condition. Refer to the Trailer Towing Weights (Maximum Trailer Weight Ratings) chart for the Max. GTW towable for your given drivetrain.

Refer to local laws for maximum trailer towing speeds.

Note 1 – 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.

STARTING AND OPERATING 279

put in or on your vehicle.

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. 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.

280 STARTING AND OPERATING

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.

• 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 in P (Park). 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 2. GTW 3. GAWR

STARTING AND OPERATING 281

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 − Proper tire inflation pressures are essential to the safe and satisfactory operation of your vehicle. Refer to “Tires–General Information” for proper tire inflation procedures.

− Also, check the trailer tires for proper tire inflation

pressures before trailer usage.

− Check for signs of tire wear or visible tire damage before towing a trailer. Refer to “Tires–General Infor- mation” for proper inspection procedure.

282 STARTING AND OPERATING

− When replacing tires, refer to “Tires–General Informa- tion” for proper tire replacement procedures. Replac- ing 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.

− An electronically actuated trailer brake controller is required when towing a trailer with electronically actuated brakes. When towing a trailer equipped with a hydraulic surge actuated brake system, an electronic brake controller is not required.

− Trailer brakes are recommended for trailers over 1,000
lbs (454 kg) and required for trailers in excess of 2,000
lbs (907 kg).

CAUTION!

If the trailer weighs more than 1,000 lbs (454 kg) loaded, it should have its own brakes and they should be of adequate capacity. Failure to do this could lead to accelerated brake lining wear, higher brake pedal effort, and longer stopping distances.

WARNING!

Do not connect trailer brakes to your vehicle’s hy- draulic brake lines. It can overload your brake sys- tem and cause it to fail. You might not have brakes when you need them and could have an accident. Towing any trailer will increase your stopping dis- tance. When towing you should allow for additional space between your vehicle and the vehicle in front of you. Failure to do so could result in an accident.

Towing Requirements — Trailer Lights & Wiring Whenever you pull a trailer, regardless of the trailer size, stop lights and turn signals on the trailer are required for motoring safety. The Trailer Tow Package may include a 4 and 7 pin wiring harness. Use a factory approved trailer harness and connector.

STARTING AND OPERATING 283

NOTE: Do not cut or splice wiring into the vehicles wiring harness. The electrical connections are all complete to the vehicle but you must mate the harness to a trailer connector. Refer to the following illustrations.

4 - Pin Connector

Towing Tips Before setting out on a trip, practice turning, stopping and backing the trailer in an area away from heavy traffic.

Towing Tips — Automatic Transmission The “D” range can be selected when towing. However, if frequent shifting occurs while in this range, the “3” range should be selected. NOTE: Using the “3” range while operating the vehicle under heavy operating conditions will improve perfor- mance and extend transmission life by reducing exces- sive shifting and heat build up. This action will also provide better engine braking. The automatic transmission fluid and filter should be changed if you REGULARLY tow a trailer for more than 45 minutes of continuous operation. See Schedule “B” in section 8 of this manual for transmission fluid change intervals. NOTE: Check the automatic transmission fluid level before towing.

Towing Tips — Electronic Speed Control (If Equipped) − Don’t use in hilly terrain or with heavy loads. − When using the speed control, if you experience speed drops greater than 10 mph (16 km/h), disengage until you can get back to cruising speed.

− Use speed control in flat terrain and with light loads to

maximize fuel efficiency.

Towing Tips — Cooling System To reduce potential for engine and transmission over- heating, take the following actions: − City Driving When stopped for short periods of time, put transmission in neutral and increase engine idle speed.

STARTING AND OPERATING 285

− Highway Driving Reduce speed. − Air Conditioning Turn off temporarily. − refer to Cooling System Operating information in the Maintenance section of this manual for more informa- tion.

RECREATIONAL TOWING (BEHIND MOTORHOME, ETC.) Recreational towing is not allowed.

288 WHAT TO DO IN EMERGENCIES

HAZARD WARNING FLASHERS Your vehicle’s hazard warning flasher is an emergency warning system. When you activate it, all front and rear directional signals will flash intermittently. Use it when your vehicle is disabled on or near the road. It warns other drivers to steer clear of you and your vehicle. This is an emergency warning system, not to be used when the vehicle is in motion.

Hazard Warning Switch

To activate the warning flasher, push down on the button on top of the steering column until it latches. To turn the warning flasher off, push down again to unlatch the button. NOTE: With extended use, the flasher may run down your battery.

IF YOUR ENGINE OVERHEATS In any of the following situations, you can reduce the potential for overheating by taking the appropriate ac- tion. • On the highways — Slow down. • In city traffic — While stopped, put transmission in N

(Neutral), but do not increase engine idle speed.

NOTE: There are steps that you can take to slow down an impending overheat condition. If your air conditioner is on, turn it off. The air conditioning system adds heat to the engine cooling system and turning off the A/C removes this heat. You can also turn the Temperature Control to maximum heat, the Mode Control to floor, and the Fan Control to High. This allows the heater core to act as a supplement to the radiator and aids in removing heat from the engine cooling system.

WHAT TO DO IN EMERGENCIES 289

CAUTION!

Driving with a hot cooling system could damage your vehicle. If the temperature gauge reads “H”, pull over and stop the vehicle. Idle the vehicle with the air conditioner turned off until the pointer drops back into the normal range. If the pointer remains on the “H”, and you hear continuous chimes, turn the engine off immediately, and call for service.

JUMP STARTING PROCEDURE

NOTE: Check the charge indicator on the battery. If the indicator is light or yellow, replace the battery. 1. Wear eye protection and remove any metal jewelry such as watch bands or bracelets that might make an unintended electrical contact.

290 WHAT TO DO IN EMERGENCIES

2. When boost is provided by a battery in another vehicle, park that vehicle within booster cable reach but without letting the vehicles touch. Set the parking brake, place the transmission in P (Park), and turn the ignition to OFF for both vehicles. 3. Turn off the heater, radio and all unnecessary electrical loads. 4. Connect one end of a jumper cable to the positive terminal of the discharged battery. Connect the other end of the same cable to the positive terminal of the booster battery. 5. Connect the other cable, first to the negative terminal of the booster battery and then connect the other end to a non-paint metal surface on the engine of the vehicle with the discharged battery. Make sure you have a good contact on the engine.

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. NOTE: To start the vehicle following connection of a booster battery, the Security Alarm System must first be disabled by cycling a front door key cylinder or by using the keyless entry transmitter.

WARNING!

Jump starting can be dangerous. To avoid personal injury or damage to electrical components in vehicle, observe the following warnings: • Battery fluid is a corrosive acid solution and can burn or even blind you. Don’t allow battery fluid to contact your eyes, skin, or clothing. Don’t lean over a battery when attaching clamps. If acid splashes in eyes or on skin, flush the area immediately with large amounts of water. • 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.

WHAT TO DO IN EMERGENCIES 291

• Never attempt to jump start a discharged battery that is frozen, because it could rupture or explode during
