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 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.
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.
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
96 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
•Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, ex-
haustion or other physical condition must exercise
care when using the seat heater. It may cause burns
even at low temperatures, especially if used for
long periods of time.
•Do not place anything on the seat that insulates
against heat, such as a blanket or cushion. This
may cause the seat heater to overheat. Sitting in a
seat that has been overheated could cause serious
burns due to the increased surface temperature of
the seat.
Vehicles Equipped with Remote Start
On models that are equipped with remote start, the
driver ’s heated seat and heated steering wheel can beprogrammed 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

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 a
maximum of 50 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 a maximum of 45 minutes.
Ventilated Seats — If Equipped
On some models, both the driver and passenger seats are
ventilated. Located in the seat cushion and seatback aresmall fans that draw the air from the passenger compart-
ment and blow air through fine perforations in the seat
cover to help keep the driver and front passenger cooler
in higher ambient temperatures.
There are two ventilated seat switches that allow the
driver and passenger to operate the seats independently.
The ventilated seat switches are located on the switch
bank in the center stack of the instrument panel, just
below the climate controls.
The ventilated seat switches are used
to control the speed of the fans located
in the seat. Press the switch once to
choose HIGH, press it a second time to
choose LOW. Pressing the switch a
third time will turn the ventilated seat

Reprogramming A Single HomeLinkButton
To reprogram a channel that has been previously trained,
follow these steps:
1. Turn the ignition switch to the ON/RUN position.
2. Press and hold the desired HomeLinkbutton until
the indicator light begins to flash after 20 seconds.Do not
release the button.
3.Without releasing the buttonproceed 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 sig-
nals to time-out (or quit) after several seconds of trans-
mission – which may not be long enough for HomeLinkto 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. Turn the ignition switch to the ON/RUN position.
2. Place the hand-held transmitter 1 to 3 in (3 to 8 cm)
away from the HomeLinkbutton you wish to program
while keeping the HomeLinkindicator light in view.
3. Continue to press and hold the HomeLinkbutton,
while you press and release (“cycle”), your hand-held
transmitter every two seconds until HomeLinkhas
successfully accepted the frequency signal. The indicator
light will flash slowly and then rapidly when fully
trained.
