If the mirror is manually folded after electrically
cycled, a potential extra button push is required
to get the mirrors back to the home position. If
the mirror does not electrically fold, check for
ice or dirt build up at the pivot area which can
cause excessive drag.

Power Folding Mirror Switch

Resetting The Power Folding Outside Mirrors
You may need to reset the power folding mirrors
if the following occurs:
The mirrors are accidentally blocked while
folding.
The mirrors are accidentally manually
folded/unfolded.
The mirrors come out of the unfolded posi -
tion.
The mirrors shake and vibrate at normal
driving speeds.
To Reset The Power Folding Mirrors:

1. Using the power folding mirror switch, move the mirror to its normal driving
(home) position.

2. Using the power folding mirror switch, move the mirror to the full retract position (this
may require multiple button pushes). This
resets them to their normal position.

NOTE:
It is not necessary to move the temperature
settings for cold or hot vehicles. The system
automatically adjusts the temperature,
mode, and blower speed to provide comfort
as quickly as possible.
The temperature can be displayed in U.S. or
Metric units by selecting the U.S./Metric
customer-programmable feature. Refer to
the “Uconnect Settings” in “Multimedia” for
further information.
To provide you with maximum comfort in the
Automatic mode during cold start-ups, the
blower fan will remain on low until the engine
warms up. The blower will increase in speed
and transition into Auto mode.
Manual Operation Override
This system offers a full complement of manual
override features. The AUTO symbol in the front
ATC display will be turned off when the system
is being used in the manual mode.
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
Before you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more,
run the air conditioning system at idle for about
five minutes, in fresh air with the blower setting
on high. This will ensure adequate system
lubrication to minimize the possibility of
compressor damage when the system is started
again.
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.
CAUTION!
Failure to follow these cautions can cause
damage to the heating elements:

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
plenum, 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
Use care when washing the inside of the
rear window. Do not use abrasive window
cleaners on the interior surface of the

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 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. 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.
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
indicator 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.
NOTE:
If the indicator light stays on constantly,
programming is complete and the garage
door/device should activate when the Home -
Link® button is pressed.
To program the two remaining HomeLink®
buttons, repeat each step for each remaining
button. DO NOT erase the channels.
If you unplugged the garage door opener/
device for programming, plug it back in at this
time. Reprogramming A Single HomeLink® Button
(Canadian/Gate Operator)
To reprogram a channel that has been
previously trained, follow these steps:

1. Place the ignition in the ON/RUN position.

2. Press 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 “Canadian/Gate Operator Programming”
step 2 and follow all remaining steps.
USING HOMELINK®
To operate, push and release the programmed
HomeLink® button. Activation will now occur for
the programmed device (i.e. garage door
opener, gate operator, security system, entry
door lock, home/office lighting, etc.) The
hand-held transmitter of the device may also be
used at any time.

210SAFETY
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
complete 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.
SAFETY CHECKS YOU SHOULD MAKE
I
NSIDE THE VEHICLE
Seat Belts
Inspect the seat belt system periodically,
checking for cuts, frays, and loose parts.
Damaged parts must be replaced immediately.
Do not disassemble or modify the system.
Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies must
be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing,
etc.). If there is any question regarding seat belt
or retractor condition, replace the seat belt.
Air Bag Warning Light
The Air Bag warning light will turn on for four
to eight seconds as a bulb check when the
ignition switch is first turned to ON/RUN. If the
light is either not on during starting, stays on, or
turns on while driving, have the system
inspected at an authorized dealer as soon as
possible. After the bulb check, this light will
illuminate with a single chime when a fault with the Air Bag System has been detected. It will
stay on until the fault is removed. If the light
comes on intermittently or remains on while
driving, have an authorized dealer service the
vehicle immediately.
Refer to “Occupant Restraint Systems” in
“Safety” for further information.
Defroster
Check operation by selecting the defrost mode
and place the blower control on high speed. You
should be able to feel the air directed against
the windshield. See an authorized dealer for
service if your defroster is inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit your
vehicle. Only use a floor mat that does not
interfere with the operation of the accelerator,
brake or clutch pedals. Only use a floor mat that
is securely attached using the floor mat
fasteners so it cannot slip out of position and
interfere with the accelerator, brake or clutch
pedals or impair safe operation of your vehicle
in other ways.
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.
