108 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, exhaus-
tion 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 or seatback 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 tempera-
ture of the seat.
Front Heated Seats
The front heated seats control buttons are located within
the climate or controls screen of the touchscreen.You can choose from HI, LO or OFF heat settings. The
indicator lights in each switch indicate the level of heat in
use. Two indicator lights will illuminate for HI, one for
LO and none for OFF.
•Press the heated seat button
once to turn the HI
setting ON.
•Press the heated seat buttona second time to turn
the LO setting ON.
•Press the heated seat buttona third time to turn
the heating elements OFF.
If the HI-level setting is selected, the system will auto-
matically switch to LO-level after approximately 60 min-
utes of continuous operation. At that time, the display
will change from HI to LO, indicating the change. The
LO-level setting will turn OFF automatically after ap-
proximately 45 minutes.

provide a boosted heat level during the first four minutes
of operation. Then, the heat output will drop to the
normal HI-level. If the HI-level setting is selected, the
system will automatically switch to LO-level after ap-
proximately 60 minutes of continuous operation. At that
time, the number of illuminated LEDs changes from two
to one, indicating the change. The LO-level setting will
turn OFF automatically after approximately 45 minutes.WARNING!

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 up
to 80 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 control button is located
within the Uconnect® system. You can gain access to the
control button through the climate screen or the controls
screen.
•Press the heated steering wheel button
once to
turn the heating element ON.
•Press the heated steering wheel buttona second
time to turn the heating element OFF.
NOTE:The engine must be running for the heated
steering wheel to operate.
Vehicles Equipped With Remote Start
On models that are equipped with remote start, the
heated steering wheel can be programmed to come on
during a remote start through the Uconnect® system.
Refer to “Uconnect® Settings” in “Understanding Your
Instrument Panel” for further information.
WARNING!
•Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, exhaus-
tion, or other physical conditions must exercise
care when using the steering wheel heater. It may

•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 buttonproceed with “Program-
ming A Non-Rolling Code” step 2 and follow all
remaining 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 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.

release of the switch, the wipers will resume the continu-
ous rear wiper operation. When this rotary control is in
the OFF position, rotating it downward will activate the
rear washer pump which will continue to operate as long
as the switch is held. Once the switch is released it will
return to the OFF position and the wipers will cycle
several times before returning to the parked position.
NOTE:As a protective measure, the pump will stop if the
switch is held for more than 20 seconds. Once the switch
is released the pump will resume normal operation.
If the rear wiper is operating when the ignition is turned
OFF, the wiper will automatically return to the “park”
position.
Rear Window Defroster
The rear window defroster button is located on
the climate control panel. Push this button to turn
on the rear window defroster and the heated outsidemirrors (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, push 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.

vehicle has completely stopped and the gear selector 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,
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.
•Electric Power Steering Malfunction – If Equipped
This telltale is on when the Electric Power
Steering is not operating and needs service.
•Liftgate Ajar
