NOTE:When removing the fuel filler cap, lay the cap
tether in the hook, located on the fuel filler door.
CAUTION!
•Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap (gas cap).
•A poorly fitting gas cap could let impurities into
the fuel system.
•A poorly fitting gas cap may cause the “Malfunc-
tion Indicator Light (MIL)” to turn on.
•To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling. When the fuel
nozzle “clicks” or shuts off, the fuel tank is full.

Towing Requirements – Trailer Lights and Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-
pin wiring harness. Use a factory approved trailer har-
ness and connector.
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.

specified for “police, taxi, fleet, or frequent trailer tow-
ing.” Refer to “Maintenance Schedule” for the proper
maintenance intervals.
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.
AutoStick

By using the AutoStickmode and selecting a specific
gear range, frequent shifting can be avoided. The
highest gear range should be selected that allows for
adequate performance. 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 range or vehicle
speed when road conditions and RPM level allows.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods, shift the transmission
into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.

8. Install the lug nuts with the cone shaped end of the
nut toward the wheel. Lightly tighten the lug nuts. To
avoid the risk of forcing the vehicle off the jack, do not
tighten the lug nuts fully until the vehicle is lowered to
the ground.
9. Lower the vehicle to the ground by turning the jack
handle counterclockwise.
10. Finish tightening the lug nuts. Push down on the
wrench while tightening for increased leverage. Alternate
lug nuts until each nut has been tightened twice. The
correct tightness of each lug nut is 100 ft/lb. (135 N·m). If
in doubt about the correct tightness, have them checked
with a torque wrench by your authorized dealer or at a
service station.
11. Stow the jack, tools and flat tire. Make sure the base
of the jack faces the rear of the vehicle before tightening
down the fastener.WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
Compact Spare Tire
The compact spare tire 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.
•Keep tire inflated to 60 psi (414 KPa) cold inflation
pressure.
•This tire is designed as an emergency spare only. Do
not exceed 50 mph (80 km/h) speed.
358 WHAT TO DO IN EMERGENCIES

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.
Wheel Cover or Center Cap Installation — If
Equipped
NOTE:Do not attempt to install a center cap or wheel
cover on the compact spare. 1. Mount the road tire on the axle. For vehicles equipped
with wheel covers, perform Steps 2 and 3. For vehicles
equipped with center caps, proceed to Step 4.
2. Install two lug nuts on the mounting studs, which are
on each side of the stud that is in alignment with the
valve stem. Install the lug nuts with the cone shaped end
of the nut toward the wheel. Lightly tighten the lug nuts.
To avoid the risk of forcing the vehicle off the jack, do not
tighten the lug nuts fully until the vehicle is lowered to
the ground.

3. Align the valve notch in the wheel cover with the
valve stem on the wheel. Install the cover by hand,snapping the cover over the two lug nuts. Do not use a
hammer or excessive force to install the cover.
4. Install the remaining lug nuts with the cone shaped
end of the nut toward the wheel. Lightly tighten the lug
nuts. To avoid the risk of forcing the vehicle off the jack,
do not tighten the lug nuts fully until the vehicle is
lowered to the ground.
5. Lower the vehicle to the ground by turning the jack
handle counterclockwise.
6. Finish tightening the lug nuts. Push down on the
wrench while tightening for increased leverage. Alternate
lug nuts until each nut has been tightened twice. The
correct tightness of each lug nut is 100 ft/lb. (135 N·m). If
in doubt about the correct tightness, have them checked
with a torque wrench by your authorized dealer or at a
service station.

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
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
”gASCAP” message will display in the odometer or a
“Check Gascap” message will display in the Electronic
Vehicle Information Center (EVIC) (if equipped). If this
occurs, tighten the fuel filler cap properly and press the
