TRAILER TOWING MIRRORS
These mirrors are designed with an adjustable
mirror head to provide a greater vision range
when towing extra-wide loads. To change
position inboard or outboard, the mirror head
should be rotated (flipped in or out).

Trailer Towing Position

NOTE:
Fold the trailer towing mirrors rearward prior to
entering an automated car wash.
A small blindspot mirror is located next to the
main mirror and can be adjusted manually.
Blindspot Mirror

HEATED MIRRORS — IF EQUIPPED
These mirrors are heated to melt frost
or ice. This feature will be activated
whenever you turn on the rear window
defroster (if equipped) Ú
page 58.
TILT SIDE MIRRORS IN REVERSE — IF
E
QUIPPED
This feature provides automatic outside mirror
positioning which will assist with the driver’s
ground visibility. The outside mirrors will move
slightly downward from the present position
when the vehicle is shifted into REVERSE. The outside mirrors will then return to the
original position when the vehicle is shifted out
of REVERSE. If the vehicle is equipped with
Driver Memory Settings, this feature will be
linked to the programmable settings.
NOTE:
The Tilt Side Mirrors In Reverse feature can be
turned on and off using the Uconnect system

50GETTING TO KNOW YOUR VEHICLE
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
HomeLink® 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
Úpage 449.
EXTERIOR LIGHTS
HEADLIGHT SWITCH
The headlight switch is located on the left side
of the instrument panel. This switch controls the
operation of the headlights, parking lights,
automatic headlights (if equipped), instrument
panel light dimming, cargo light/trailer spotter
lights (if equipped), and fog lights (if equipped).
