AUTOMATIC TRANSMISSION OVERHEATING
During sustained high speed driving or trailer towing up long grades on hot days, the
automatic transmission oil may become too hot.
If the transmission overheat warning light
turns on, you will experience reduced
performance until the automatic transmission cools down. Stop the vehicle and run
the engine at idle with the transmission in NEUTRAL until the light turns off. Once
the transmission has cooled down and the light turns off, you may continue to drive
normally. If the high speed is maintained, the overheating may reoccur.
JACKING AND TIRE CHANGING
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.
• Being under a jacked-up vehicle is dangerous. The vehicle could slip off the
jack and fall on you. You could be crushed. Never put any part of your body
under a vehicle that 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.
• Never start or run the engine while the vehicle is on a jack.
• The jack is designed to be used as a tool for changing tires only. The jack
should not be used to lift the vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or slippery areas.
Jack Location
The jack and jack-handle are stowed under the load floor in the cargo area.

3. Turn the jack screw to the left until the jack can be placed under the jackinglocation. Once the jack is positioned, turn the jack screw to the right until the jack
head is properly engaged with the lift area closest to the wheel to be changed.
WARNING!
Raising the vehicle higher than necessary can make the vehicle less stable. It
could slip off the jack and hurt someone near it. Raise the vehicle only enough to
remove the tire.
4. Using the swivel wrench raise the vehicle by turning the jack screw to the right. Raise the vehicle only until the tire just clears the surface and enough clearance
is obtained to install the spare tire. Minimum tire lift provides maximum stability.
5. Remove the wheel nuts and pull the wheel and wheel covers, where applicable, off the hub. Install the spare wheel and wheel nuts with the cone shaped end of the
nuts toward the wheel. Lightly tighten the nuts.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do not tighten the wheel nuts
fully until the vehicle has been lowered. Failure to follow this warning may result
in serious injury.
CAUTION!
Be sure to mount the spare tire with the valve stem facing outward. The vehicle
could be damaged if the spare tire is mounted incorrectly.

Road Tire Installation
Vehicles Equipped With Wheel Covers
1. Mount the road tire on the axle.
2. Align the valve notch in the wheel cover with the valve stem on the wheel. Installthe cover by hand. Do not use a hammer or excessive force to install the cover.
3. Install the five wheel lug nuts with the cone shaped end of the nut toward the wheel. Lightly tighten the lug nuts.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do not tighten the lug nuts fully
until the vehicle has been lowered. Failure to follow this warning may result in
serious injury.
4. Lower the vehicle to the ground by turning the jack handle counterclockwise.
5. Finish tightening the lug nuts. Push down on the wrench while at the end of the handle for increased leverage. Tighten the lug nuts in a star pattern until each nut
has been tightened twice. The correct tightness of each lug nut is 100 ft/lbs (135
N·m). If in doubt about the correct tightness, have them checked with a torque
wrench by your authorized dealer or service station.
6. After 25 miles (40 km) check the lug nut torque with a torque wrench to ensure that all lug nuts are properly seated against the wheel.

JUMP-STARTING PROCEDURES
If your vehicle has a discharged battery it can be jump-started using a set of jumper
cables and a battery in another vehicle or by using a portable battery booster pack.
Jump-starting can be dangerous if done improperly so please follow the procedures
in this section carefully.
NOTE:
When using a portable battery booster pack follow the manufacturer’s operating
instructions and precautions.
CAUTION!
Do not use a portable battery booster pack or any other booster source with a
system voltage greater than 12 Volts or damage to the battery, starter motor,
alternator or electrical system may occur.
WARNING!
Do not attempt jump-starting if the battery is frozen. It could rupture or explode
and cause personal injury.

MAINTENANCE PROCEDURES
For information on the maintenance procedures for your vehicle, please refer to
“Maintenance Procedures” in “Maintaining Your Vehicle” in your Owner’s Manual or
applicable supplement on the DVD for further details.
MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change indicator system. The oil
change indicator system will remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change indicator message will
illuminate. This means that service is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or cold ambient temperatures
will influence when the “Change Oil” or “Oil Change Required” message is dis-
played. Severe Operating Conditions can cause the change oil message to illuminate
as early as 3,500 miles (5,600 km) since last reset. Have your vehicle serviced as
soon as possible, within the next 500 miles (805 km).
On Electronic Vehicle Information Center (EVIC) equipped vehicles, “Oil Change
Required” will be displayed in the EVIC and a single chime will sound, indicating that
an oil change is necessary.
On Non-EVIC equipped vehicles, “Change Oil” will flash in the instrument cluster
odometer and a single chime will sound, indicating that an oil change is necessary.
Your authorized dealer will reset the oil change indicator message after completing
the scheduled oil change. If a scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by referring to the steps
described under “Instrument Cluster Warning Lights” in “What To Do In Emergen-
cies” in this guide or “Instrument Cluster Descriptions” or “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your Instrument Panel” in the
Owner’s Manual on your DVD for further information.
NOTE:
Under no circumstances should oil change intervals exceed 10,000 miles
(16,000 km), twelve months or 350 hours of engine run time, whichever comes first.
The 350 hours of engine run or idle time is generally only a concern for fleet
customers.

Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) if the vehicle is operated in a dusty
and off road environment or is operated predominately at idle or only very low engine
RPM’s. This type of vehicle use is considered Severe Duty.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual wear or damage
• Check the fluid levels of the coolant reservoir, brake master cylinder, powersteering and fill as needed
• Check function of all interior and exterior lights
Required Maintenance Intervals.
Refer to the maintenance schedules on the following page for the required mainte-
nance intervals.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
• Change oil and filter.
• Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil
indicator system turns on.
• Inspect battery and clean and tighten terminals as required.
• Inspect brake pads, shoes, rotors, drums, hoses and park brake.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or off-road conditions.
