does not operate, repeat the steps from the
beginning.
PROGRAMMING HOMELINK® TO A
M
ISCELLANEOUS DEVICE

Follow the procedure on programming HomeLink® to a
garage door opener
Ú
page 39. Be sure to determine
if the device has a rolling code, or non-rolling code
before beginning the programming process.

NOTE: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. The procedure may need to be
performed multiple times to successfully pair the
device to your HomeLink® buttons.
REPROGRAMMING A SINGLE
H
OMELINK® BUTTON
To reprogram a single HomeLink® button that has
been previously trained, without erasing all the
channels, follow the procedure below. Be sure to
determine whether the new device you want to
program the HomeLink® button to has a rolling
code or non-rolling code.

1. Place the ignition in the ON/RUN position,
without starting the engine.
2. Push and hold the desired HomeLink® button until
the HomeLink® Indicator light begins to flash after
20 seconds. Do not release the button.
3. Without releasing the button , proceed with Step
2 in “Programming HomeLink® To A Garage Door
Opener” and follow all remaining steps.

CANADIAN/GATE OPERATOR
P
ROGRAMMING
For programming transmitters in Canada/United
States that require the transmitter signals to
“time-out” after several seconds of transmission.

Canadian Radio Frequency (RF) 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 US
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. Place the ignition in the ON/RUN position.

2. Place the hand-held transmitter 1 to 3 inches
(3 to 8 cm) away from the HomeLink® button
you wish to program while keeping the
HomeLink® indicator light in view.
WARNING!
Your motorized door or gate will open and
close while you are programming the universal
transceiver. Do not program the transceiver if
people or pets are in the path of the door or
gate.
Do not run your vehicle in a closed garage or
confined area while programming the trans -
ceiver. Exhaust gas from your vehicle contains
Carbon Monoxide (CO) which is odorless and
colorless. Carbon Monoxide is poisonous
when inhaled and can cause you and others to
be severely injured or killed.

TIP:Voice Command for Climate may only be used to
adjust the interior temperature of your vehicle.
Voice Command will not work to adjust the heated
seats or steering wheel if equipped.
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.

Winter Operation
To ensure the best possible heater and defroster
performance, make sure the engine cooling
system is functioning properly and the proper
amount, type, and concentration of coolant is
used. Use of the Air Recirculation mode during
Winter months is not recommended, because it
may cause window fogging.
Vacation/Storage
For information on maintaining the Climate Control
system when the vehicle is being stored for an
extended period of time, see Úpage 292.
Window Fogging

Vehicle windows tend to fog on the inside in mild, rainy,
and/or humid weather. To clear the windows, select
Defrost or Mix mode and increase the front blower
speed. Do not use the Recirculation mode without A/C
for long periods, as fogging may occur.

Outside Air Intake
Make sure the air intake, located directly in front of
the windshield, is free of obstructions, such as
leaves. Leaves collected in the air intake may
reduce airflow, and if they enter the air distribution
box, they could plug the water drains. In Winter
months, make sure the air intake is clear of ice,
slush, and snow.
Cabin Air Filter
The Climate Control system filters out dust and
pollen from the air. Contact an authorized dealer to
service your cabin air filter, and to have it replaced
when needed.
Operating Tips Chart
NOTE:The below chart is for Manual Override Operation,
otherwise run in AUTO.
WEATHER CONTROL SETTINGS
Hot Weather And
Vehicle Interior Is Very Hot Set the mode control to
(Panel Mode), (MAX A/C) on, and blower on high. Roll down the windows for a
minute to flush out the hot air. Adjust the controls as
needed to achieve comfort.
Warm Weather Turn (A/C) on and set the
mode control to (Panel Mode).
Cool Sunny Operate in (Bi-Level
Mode).
Cool & Humid Conditions Set the mode control to
(Mix Mode) and turn on
(A/C) to keep windows clear.
Cold Weather Set the mode control to
(Floor Mode). If windshield
fogging starts to occur, move
the control to (Mix Mode).

IN CASE OF EMERGENCY239
Emergency Gas Can Refueling
Most gas cans will not open the flapper doors.
A funnel is provided to allow emergency refueling
with a gas can.
See below steps for refueling:

1. Retrieve funnel from the spare tire storage area.

2. Insert funnel into same filler pipe opening as the fuel nozzle.

Inserting Funnel

3. Ensure funnel is inserted fully to hold flapper doors open. 4. Pour fuel into funnel opening.
5. Remove funnel from filler pipe, clean off prior
to putting back in the spare tire storage area.
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
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 trans -
mission in NEUTRAL, but do not increase the
engine idle speed while preventing vehicle
motion with the brakes.
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.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc -
tion Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.

242IN CASE OF EMERGENCY
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. For vehicles with
automatic transmission, push and hold the lock
button on the gear selector. Then shift back and
forth between DRIVE and REVERSE (with automatic
transmission) or FIRST gear and REVERSE (with
manual transmission), while gently pressing the
accelerator. Use the least amount of accelerator
pedal pressure that will maintain the rocking motion,
without spinning the wheels or racing the engine.

NOTE:
For vehicles with automatic transmission: Shifts
between DRIVE and REVERSE can only be achieved
at wheel speeds of 5 mph (8 km/h) or less.
Whenever the transmission remains in NEUTRAL for
more than two seconds, you must press the brake
pedal to engage DRIVE or REVERSE.

Push the ESC OFF button to place the Electronic
Stability Control (ESC) system in “Partial OFF”
mode, before rocking the vehicle Ú page 182.
Once the vehicle has been freed, push the ESC OFF
button again to restore “ESC On” mode.
CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission
in NEUTRAL for at least one minute after every
five rocking-motion cycles. This will minimize
overheating and reduce the risk of clutch or
transmission failure during prolonged efforts to
free a stuck vehicle.
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.

CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission
in NEUTRAL for at least one minute after every
five rocking-motion cycles. This will minimize
overheating and reduce the risk of transmis -
sion failure during prolonged efforts to free a
stuck vehicle.
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 transmission shifting occurring).

SERVICING AND MAINTENANCE259
Under normal operating conditions, the catalytic
converter will not require maintenance. However, it
is important to keep the engine properly tuned to
ensure proper catalyst operation and prevent
possible catalyst damage.
NOTE:Intentional tampering with emissions control
systems 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 igni-
tion 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 diag
-
nostic testing, or for prolonged periods during
very rough idle or malfunctioning operating
conditions.
NOTE:The vehicle exhaust system may be equipped with
an Electronic Exhaust Valve (EEV) system, if the
exhaust system is replaced with aftermarket
products a Malfunction Indicator Lamp (MIL) will
illuminate.
COOLING SYSTEM CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness 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 condi -
tion. In the event of engine malfunction, particu-
larly involving engine misfire or other apparent
loss of performance, have your vehicle serviced
promptly. Continued operation of your vehicle with
a severe malfunction could cause the converter to
overheat, resulting in possible damage to the
converter and vehicle.

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 open a
cooling system pressure cap when the radi -
ator or coolant bottle is hot.
Keep hands, tools, clothing, and jewelry away
from the radiator cooling fan when the hood is
raised. The fan starts automatically and may
start at any time, whether the engine is
running or not.
When working near the radiator cooling fan,
disconnect the fan motor lead or turn the igni -
tion to the OFF mode. The fan is temperature
controlled and can start at any time the igni -
tion is in the ON mode.

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
Fuel Economy
Tread Wear
Ride Comfort and Vehicle Stability
Safety Both underinflation and overinflation 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.
Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause
abnormal wear patterns and reduced tread life,
resulting in the need for earlier tire replacement. Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable
ride. Overinflation produces a jarring and
uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on
the driver's side B-pillar or rear edge of the driver's
side door.
At least once a month:
Check and adjust tire pressure with a good
quality pocket-type pressure gauge. Do not
make a visual judgement when determining
proper inflation. Tires may look properly inflated
even when they are underinflated.
Inspect tires for signs of tire wear or visible
damage.
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.
Overinflated or underinflated tires can affect
vehicle handling and can fail suddenly,
resulting in loss of vehicle control.

Unequal tire pressures can cause steering prob
-
lems. 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
recommended cold tire inflation pressure.
WARNING!
CAUTION!
After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the valve stem.8
