3. Push and hold the Homelink button you want toprogram while you push and hold the hand-held trans-
mitter button.
4. Continue to hold both buttons and observe the indicator light. The Homelink indicator will flash slowly and then
rapidly after HomeLink has received the frequency
signal from the hand-held transmitter. Release both
buttons after the indicator light changes from slow to
rapid.
5. Push and hold the programmed HomeLink button and observe the indicator light.
• If the indicator light stays on constantly, programming
is complete and the garage door/device should acti-
vate when the HomeLink button is pushed.
• To program the two remaining HomeLink buttons,
repeat each step for each remaining button. DO NOT
erase the channels.
Reprogramming A Single HomeLink Button
(Non-Rolling Code)
To reprogram a channel that has been previously trained,
follow these steps:
1. Cycle the ignition to the ON/RUN position. 2. Push and hold the desired HomeLink button until the
indicator light begins to flash after 20 seconds. Do not
release the button.
3. Without releasing the button, proceed with “Program-
ming A Non-Rolling Code” step 2 and follow all remain-
ing steps.
Canadian/Gate Operator Programming
For programming transmitters in Canada/United States
that require the transmitter signals to “time-out” after
several seconds of transmission:
Canadian radio frequency laws require transmitter signals
to time-out (or quit) after several seconds of transmission,
which may not be long enough for HomeLink to pick up
the signal during programming. Similar to this Canadian
law, some U.S. gate operators are designed to time-out in
the same manner.
It may be helpful to unplug the device during the cycling
process to prevent possible overheating of the garage door
or gate motor.
1. Cycle the ignition to the ON/RUN position.

Coolant Temperature Warning Light
Red TelltaleLight What It Means
Coolant Temperature Warning Light
This light warns of an overheated engine condition. If the light turns on while driving, safely pull
over and stop the vehicle. If the A/C system is on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the temperature reading does not return to normal, turn the
engine off immediately and call for service.
NOTE:
As the coolant temperature gauge approaches
H,a Red Dot lamp located to the left of the “H”
will illuminate and a single chime will sound. Further overheating will cause the temperature
gauge to pass H.In this case, a continuous chime will sound until the engine is allowed to cool
or the 4 minute duration is expired, whichever comes first.

Rear Mode Control
•Headliner Mode
Air comes from the outlets in the headliner. Each of
these outlets can be individually adjusted to direct
the flow of air. Moving the air vanes of the outlets to one
side will shut off the airflow.
• Bi-Level Mode
Air comes from both the headliner outlets and the
floor outlets.
NOTE: In many temperature positions, the Bi-Level mode
is designed to provide cooler air out of the headliner
outlets and warmer air from the floor outlets.
• Floor Mode
Air comes from the floor outlets.
Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended. Refer
to “Maintenance Procedures” in “Maintaining Your Ve-
hicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration
of coolant is used. Refer to “Maintenance Procedures” in
“Maintaining Your Vehicle” for proper coolant selection.
Use of the air Recirculation mode during Winter months is
not recommended, because it may cause window fogging.

TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Four primary areas
are affected by improper tire pressure:
•Safety and Vehicle Stability
• Economy
• Tread Wear
• Ride Comfort
Safety
WARNING!
•Improperly inflated tires are dangerous and can
cause collisions.
• Underinflation increases tire flexing and can result
in overheating and tire failure.
• Overinflation reduces a tire’s ability to cushion
shock. Objects on the road and chuckholes can cause
damage that result in tire failure.
(Continued)
WARNING! (Continued)
•Overinflated or underinflated tires can affect vehicle
handling and can fail suddenly, resulting in loss of
vehicle control.
• Unequal tire pressures can cause steering problems.
You could lose control of your vehicle.
• Unequal tire pressures from one side of the vehicle
to the other can cause the vehicle to drift to the right
or left.
• Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Both under-inflation and over-inflation affect the stability
of the vehicle and can produce a feeling of sluggish
response or over responsiveness in the steering.
NOTE:
• Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
• Unequal tire pressure from side to side may cause the
vehicle to drift left or right.

STARTING AND OPERATING 379

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located in the lower
center area of the instrument panel.Push the switch to turn on the Hazard Warning
flasher. When the switch is activated, all directional
turn signals will flash on and off to warn oncoming traffic
of an emergency. Push the switch a second time to turn off
the Hazard Warning flashers.
This is an emergency warning system and it should not be
used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position.
NOTE: With extended use, the Hazard Warning flashers
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate action.
• On the highways — slow down. •
In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down an
impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement
to the radiator and aids in removing heat from the
engine cooling system.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap when
the radiator or coolant bottle is hot.
422 WHAT TO DO IN EMERGENCIES

CAUTION!
Accessories plugged into the vehicle power outlets
draw power from the vehicle’s battery, even when not
in use (i.e., cellular devices, etc.). Eventually, if plugged
in long enough without engine operation, the vehicle’s
battery will discharge sufficiently to degrade battery
life and/or prevent the engine from starting.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front
wheels. Then shift back and forth between DRIVE and
REVERSE while gently pressing the accelerator. Use the
least amount of accelerator pedal pressure that will main-
tain the rocking motion, without spinning the wheels or
racing the engine.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the transmission in NEUTRAL for at
(Continued)
CAUTION!(Continued)
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce the
risk of transmission failure during prolonged efforts to
free a stuck vehicle.
NOTE: Push the ESC Off switch, to place the Electronic
Stability Control (ESC) system in Partial Offmode before
rocking the vehicle. Refer to “Electronic Brake Control
System” in “Starting and Operating” for further informa-
tion. Once the vehicle has been freed, push the ESC Off
switch again to restore ESC Onmode.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause damage, or even
failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle’s wheels
faster than 30 mph (48 km/h) or for longer than 30
seconds continuously without stopping when you are
stuck and do not let anyone near a spinning wheel, no
matter what the speed.

WHAT TO DO IN EMERGENCIES 451

CAUTION!
•When “rocking” a stuck vehicle by shifting between
DRIVE and REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.
• Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure. It
can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmis-
sion shifting occurring).
GEAR SELECTOR OVERRIDE
If a malfunction occurs and the gear selector cannot be
moved out of the PARK position, you can use the following
procedure to temporarily move the gear selector:
1. Turn the engine OFF.
2. Firmly apply the parking brake.
3. Using a small screwdriver or similar tool, remove the
gear selector override access cover (located near the top
right of the gear selector in the instrument panel). 4. Press and maintain firm pressure on the brake pedal.
5. Insert the screwdriver or similar tool into the access
hole, and push and hold the override release lever
forward.
6. Move the gear selector to the NEUTRAL position.
7. The vehicle may then be started in NEUTRAL.
8. Reinstall the gear selector override access cover.

WARNING!(Continued)
•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.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs, stop the
vehicle, turn off the engine and allow it to cool. Service,
including a tune-up to manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter damage:
• Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion.
• Do not try to start the engine by pushing or towing the
vehicle.
• Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating conditions.7
