Automatic Transmission
Select the DRIVE range when towing. The transmission
controls include a drive strategy to avoid frequent shifting
when towing. However, if frequent shifting does occur
while in DRIVE, you can use the AutoStick shift control to
manually select a lower gear.
NOTE:Using a lower gear while operating the vehicle
under heavy loading conditions, will improve performance
and extend transmission life by reducing excessive shifting
and heat buildup. This action will also provide better
engine braking.
AutoStick
• When using the AutoStick shift control, select the high-
est gear that allows for adequate performance and
avoids frequent downshifts. For example, choose “5” if
the desired speed can be maintained. Choose “4” or “3”
if needed to maintain the desired speed.
• To prevent excess heat generation, avoid continuous
driving at high RPM. Reduce vehicle speed as necessary
to avoid extended driving at high RPM. Return to a
higher gear or vehicle speed when grade and road
conditions allow.
Speed Control — If Equipped
• Do not use on 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.
Cooling System
To reduce potential for engine and transmission overheat-
ing, take the following actions:
City Driving
• In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase engine idle speed.
Highway Driving
• Reduce speed.
• Temporarily turn off air conditioning.

Connecting The Jumper Cables
1. Connect the positive(+)end of the jumper cable to the
remote positive (+)post of the discharged vehicle.
2. Connect the opposite end of the positive (+)jumper
cable to the positive (+)post of the booster battery.
3. Connect the negative end (-)of the jumper cable to the
negative (-)post of the booster battery.
4. Connect the opposite end of the negative (-)jumper
cable to the remote negative (-)post of the vehicle with
the discharged battery.
WARNING!
Do not connect the jumper cable to the negative (-) post
of the discharged battery. The resulting electrical spark
could cause the battery to explode and could result in
personal injury. Only use the specific ground point, do
not use any other exposed metal parts.
5. Start the engine in the vehicle that has the booster battery, let the engine idle a few minutes, and then start
the engine in the vehicle with the discharged battery.
CAUTION!
Do not run the booster vehicle engine above 2,000 rpm
since it provides no charging benefit, wastes fuel, and
can damage booster vehicle engine.
6. Once the engine is started, remove the jumper cables in the reverse sequence:
Disconnecting The Jumper Cables
1. Disconnect the negative (-)end of the jumper cable from
the remote negative (-)post of the discharged vehicle.
2. Disconnect the opposite end of the negative (-)jumper
cable from the negative (-)post of the booster battery.
3. Disconnect the positive (+)end of the jumper cable from
the positive (+)post of the booster battery.
4. Disconnect the opposite end of the positive (+)jumper
cable from the remote positive (+)post of the discharged
vehicle.
5. Reinstall the protective cover over the remote positive (+) post of the discharged vehicle.
384 IN CASE OF EMERGENCY
At Each Stop For Fuel
•Check the engine oil level. Refer to “Engine Compart-
ment” in this section for further information.
• Check the windshield washer solvent and add if re-
quired.
Once A Month
• Check tire pressure and look for unusual wear or
damage.
• Inspect the battery, and clean and tighten the terminals
as required.
• Check the fluid levels of the coolant reservoir, engine oil,
brake master cylinder, and add as needed.
• Check all lights and other electrical items for correct
operation. At Each Oil Change
•
Change the engine oil filter.
• Inspect the brake hoses and lines.
• Rotate the tires. Rotate at the first sign of irregular
wear, even if it occurs before the oil indicator system
turns on.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
394 SERVICING AND MAINTENANCE
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals, such as every fuel stop.
The best time to check the engine oil level is about five
minutes after a fully warmed up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the dipstick.
Adding one quart of oil when the reading is at the bottom
of the SAFE zone will result in a reading at the top of the
safe zone on these engines.
CAUTION!
Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.
Adding Washer Fluid
The instrument cluster display will indicate when the
washer fluid level is low. When the sensor detects a low
fluid level, the windshield will light on the vehicle graphic
outline and the “WASHER FLUID LOW” message will be
displayed.The fluid reservoir for the windshield washers and the rear
window washer is shared. The fluid reservoir is located in
the engine compartment, be sure to check the fluid level at
regular intervals. Fill the reservoir with windshield washer
solvent only (not radiator antifreeze). When refilling the
washer fluid reservoir, take some washer fluid and apply it
to a cloth or towel and wipe clean the wiper blades, this
will help blade performance. To prevent freeze-up of your
windshield washer system in cold weather, select a solu-
tion or mixture that meets or exceeds the temperature
range of your climate. This rating information can be found
on most washer fluid containers.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around the
washer solution.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic mainte-
nance required.

SERVICING AND MAINTENANCE 399
If you notice a change in the sound of the exhaust system;
or if the exhaust fumes can be detected inside the vehicle;
or when the underside or rear of the vehicle is damaged;
have an authorized technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams or
loose connections could permit exhaust fumes to seep into
the passenger compartment. In addition, have the exhaust
system inspected each time the vehicle is raised for lubri-
cation or oil change. Replace as required.
WARNING!
•Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO, refer
to “Safety Tips” in “Safety” for further information.
• A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
CAUTION!
• The catalytic converter requires the use of unleaded
fuel only. Leaded gasoline will destroy the effective-
ness of the catalyst as an emissions control device
and may seriously reduce engine performance and
cause serious damage to the engine.
• 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.
Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to assure proper catalyst
operation and prevent possible catalyst damage.
NOTE: Intentional tampering with emissions control sys-
tems can result in civil penalties being assessed against
you.
