each tire with the low tire pressure values shown in a
different color. An#Inflate Tire to XX#message will also
be displayed in the DID display.
Should this occur, you should stop as soon as possible
and inflate all of the tires with a low pressure condition
(those shown in a different color in the DID graphic) to
the vehicle’s recommended cold placard pressure infla-
tion value as shown in the#Inflate Tire to XX#message.
Once the system receives the updated tire pressures, the
system will automatically update, the graphic display in
the DID will return the pressure values to shown their
original color, and the pressure values shown in the
“TPM Telltale Light” will turn off. The vehicle may need
to be driven for up to 20 minutes above 15 mph
(24 km/h) in order for the TPMS to receive this informa-
tion.
Service TPMS Warning
If a system fault is detected, the “TPM Telltale Light” will
flash on and off for 75 seconds and then remain on solid.
The system fault will also sound a chime. In addition, the
DID will display a#SERVICE TPM SYSTEM#message for
a minimum of five seconds and then display dashes (- -)
in place of the pressure value to indicate which sensor is
not being received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the “TPM Telltale Light” will no longer
flash, and the#SERVICE TPM SYSTEM#message will no
longer display, and a pressure value will display in place
of the dashes. A system fault can occur due to any of the
following:
1. Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.

CAUTION!(Continued)
•The use of fuel additives, which are now being
sold as octane enhancers, is not recommended.
Most of these products contain high concentrations
of methanol. Fuel system damage or vehicle perfor-
mance problems resulting from the use of such
fuels or additives is not the responsibility of the
manufacturer.
NOTE:Intentional tampering with the emissions control
system can result in civil penalties being assessed 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.

Towing Requirements — Trailer Brakes
•Donotinterconnect 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).
WARNING!
•Do not connect trailer brakes to your vehicle’s
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have a
collision.
•Towing any trailer will increase your stopping
distance. When towing you should allow for addi-
tional space between your vehicle and the vehicle
in front of you. Failure to do so could result in a
collision.
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

CAUTION!(Continued)
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
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.

Towing Tips
Before setting out on a trip, practice turning, stopping,
and backing up the trailer in an area located away from
heavy traffic.
Automatic Transmission — If Equipped
The DRIVE range can be selected 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 perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up. This action will also
provide better engine braking.

446 STARTING AND OPERATING

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®
•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.
•To prevent excess heat generation, avoid continuous
driving at high RPM. Reduce vehicle speed as neces-
sary to avoid extended driving at high RPM. Return to
a higher gear or vehicle speed when grade and road
conditions allow.
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.

STARTING AND OPERATING 447

NOTE:
•For vehicles so equipped, do not attempt to install a
center cap or wheel cover on the compact spare.
•Refer to “Compact Spare Tire” and to “Limited-Use
Spare” under “Tires—General Information” in
“Starting And Operating” for additional warnings,
cautions, and information about the spare tire, its
use, and operation.
8. Install the lug nuts with the cone shaped end of the lug
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 personal injury.
9. Lower the vehicle to the ground by turning the jack
handle counterclockwise.
10. Refer to “Torque Specifications” in this section for
proper lug nut torque.
11. Stow the jack, tools and flat tire. Make sure the base
of the jack faces the front 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. Have the deflated (flat) tire
repaired or replaced immediately.
Road Tire Installation
1. Mount the road tire on the axle.
