NOTE:Using a lower gear while operating the vehicle
under heavy loading 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.
If you REGULARLY TOW a trailer for more than 45 min-
utes of continuous operation, then change the automatic
transmission fluid and filter as specified for “police, taxi,
fleet, or frequent trailer towing.” Refer to the “Mainte-
nance Schedule” for the proper maintenance intervals.
NOTE: Check the transmission fluid level (four-speed
transmission only) before towing. The six-speed trans-
mission does not require a fluid level check before
towing. If, however, you notice fluid leakage or transmis-
sion malfunction, see your authorized dealer immedi-
ately for assistance.AutoStick® – If Equipped
– When using the AutoStick® shift control, select the highest gear that allows for adequate performance and
avoids frequent downshifts. For example, choose “4” if
the desired speed can be maintained. Choose “3” or
“2” if needed to maintain the desired speed.
– Extended driving at high RPM should be avoided to prevent excess heat generation. A reduction in vehicle
speed may be required to avoid extended driving at
high RPM. Return to a higher gear or vehicle speed
when grade and road conditions allow.
Electronic Speed Control – If Equipped
• Do not 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.

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.
5. Raise the vehicle by turning the jack screw to the right, using the swivel wrench. 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.
6. 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.

6. Finish tightening the lug nuts. Push down on thewrench 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 tight-
ness 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.
7. 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.
Vehicles Without Wheel Covers
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the cone shapedend of the nut toward the wheel. Lightly tighten the

JUMP-STARTING
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.
Preparations For Jump-Start
The battery in your vehicle is located between the left
front headlight assembly and the left front wheel splash
shield. To allow jump-starting there are remote battery
posts located on the left side of the engine compartment.

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, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light” (MIL). It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and drivability. The
vehicle must be serviced before any emissions tests
can be performed.
• If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is possibly loose or
improperly installed. A “GASCAP” message will be
displayed in the instrument cluster. Tighten the gas cap
until a clicking sound is heard. This is an indication that7
MAINTAINING YOUR VEHICLE 425

the gas cap is properly tightened. Press the trip odometer
“Reset” button to turn off the message. If the problem
persists, the message will appear the next time the
vehicle is started. This might indicate a damaged cap. If
the problem is detected twice in a row, the system will
turn on the “Malfunction Indicator Light (MIL).” Resolv-
ing the problem will turn the MIL light off.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not
on when the engine is running, and that the OBD II
system is ready for testing. Normally, the OBD II system will be ready. The OBD II
system may
notbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD II system is ready, you must
do the following:
1. Turn the ignition switch to the ON position, but do not crank or start the engine.
2. If you crank or start the engine, you will have to start this test over.
3. As soon as you turn the ignition switch to the ON position, you will see the MIL symbol come on as part
of a normal bulb check.
