Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO),
follow these safety tips:
•Do not run the engine in a closed garage or in
confined areas any longer than needed to move
your vehicle in or out of the area.
•If you are required to drive with the trunk/liftgate
open, make sure that all windows are closed and
the climate control BLOWER switch is set at high
speed. DO NOT use the recirculation mode.
•If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
controls to force outside air into the vehicle. Set the
blower at high speed.The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
110 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Vehicles Equipped with Remote Start
On models that are equipped with remote start, the
driver ’s heated seat and heated steering wheel can be
programmed to come on during a remote start. Refer to
“Remote Starting System — If Equipped” in “Things To
Know Before Starting Your Vehicle” for further informa-
tion.
Front Heated Seats
There are two heated seat switches that allow the driver
and passenger to operate the seats independently. The
controls for each heater are located near the bottom
center of the instrument panel (below the climate con-
trols).
You can choose from HIGH, LOW or OFF heat settings.
Amber indicator lights in each switch indicate the level of
heat in use. Two indicator lights will illuminate for
HIGH, one for LOW and none for OFF.Press the switch once to select HIGH-level
heating. Press the switch a second time to select
LOW-level heating. Press the switch a third
time to shut the heating elements OFF.
NOTE:Once a heat setting is selected, heat will be felt
within two to five minutes.
When the HIGH-level setting is selected, the heater will
provide a boosted heat level during the first four minutes
of operation. Then, the heat output will drop to the
normal HIGH-level. If the HIGH-level setting is selected,
the system will automatically switch to LOW-level after
approximately 60 minutes of continuous operation. At
that time, the number of illuminated LEDs changes from
two to one, indicating the change. The LOW-level setting
will turn OFF automatically after approximately 45 min-
utes.

HEATED STEERING WHEEL — IF EQUIPPED
The steering wheel contains a heating element that helps
warm your hands in cold weather. The heated steering
wheel has only one temperature setting. Once the heated
steering wheel has been turned on it will operate for
approximately 30 to 95 minutes before automatically
shutting off. The heated steering wheel can shut off early
or may not turn on when the steering wheel is already
warm.
The heated steering wheel switch is located on the switch
bank below the climate controls. There are also soft keys
in the radio screen that will activate the heated steering
wheel.Press the switch to turn on the heated
steering wheel. The light on the switch
will illuminate to indicate the steering
wheel heater is on. Pressing the switch
a second time will turn off the heated
steering wheel and light indicator.
NOTE:The engine must be running for the heated
steering wheel to operate.

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 sig-
nals to time-out (or quit) after several seconds of trans-
mission – 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.
2.
Place the hand-held transmitter 1 to 3 in (3 to 8 cm)
away from the HomeLink® button you wish to program
while keeping the HomeLink® indicator light in view.
3. Continue to press and hold the HomeLink® button,
while you press and release (“cycle”), your hand-held
transmitter every two seconds until HomeLink® has
successfully accepted the frequency signal. The indi-
cator light will flash slowly and then rapidly when
fully trained.
4. Watch for the HomeLink® indicator to change flash
rates. When it changes, it is programmed. It may take
up to 30 seconds or longer in rare cases. The garage
door may open and close while you are programming.
5. Press and hold the programmed HomeLink® button
and observe the indicator light.
•If the indicator light stays on constantly, program-
ming is complete and the garage door/device should
activate when the HomeLink® button is pressed.
•To program the two remaining HomeLink® buttons,
repeat each step for each remaining button. DO NOT
erase the channels.

If the rear wiper is operating when the ignition is turned
OFF, the wiper will automatically return to the “park”
position.
If the flipper glass is open, the rear window wiper/
washer functionality is interrupted and the wiper stops at
that “park” position. When the flipper glass is closed, the
rear wiper will resume wiper/washer functionality after
five seconds.
Rear Window Defroster
The rear window defroster button is located on
the climate control panel. Press this button to turn
on the rear window defroster and the heated outside
mirrors (if equipped). An indicator in the button will
illuminate when the rear window defroster is on. The
rear window defroster automatically turns off after ap-
proximately 10 minutes. For an additional five minutes of
operation, press the button a second time.NOTE:To prevent excessive battery drain, use the rear
window defroster only when the engine is operating.
CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
•Use care when washing the inside of the rear
window. Do not use abrasive window cleaners on
the interior surface of the window. Use a soft cloth
and a mild washing solution, wiping parallel to the
heating elements. Labels can be peeled off after
soaking with warm water.
•Do not use scrapers, sharp instruments, or abrasive
window cleaners on the interior surface of the
window.
•Keep all objects a safe distance from the window.

If a problem is detected, the light will come on while the
engine is running. Cycle the ignition key when the
vehicle has completely stopped and the shift lever is
placed in the PARK position. The light should turn off.
If the light remains lit with the engine running, your
vehicle will usually be drivable. However, see an autho-
rized dealer for service as soon as possible. If the light is
flashing when the engine is running, immediate service is
required. You may experience reduced performance, an
elevated/rough idle or engine stall and your vehicle may
require towing.
•Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proachesH,this indicator will illuminate and a single
chime will sound after reaching a set threshold. Further
overheating will cause the temperature gauge to passH,the indicator will continuously flash and a continuous
chime will occur until the engine is allowed to cool.
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 ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for more information.
•Transmission Temperature Warning Light
This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as 4-wheel-drive
operation (e.g., snow plowing, off- road operation). If this
