H
OMELINK®
For efficient programming and accurate
transmission of the Radio Frequency (RF) signal, it
is recommended that a new battery be placed in
the hand-held transmitter of the device that is
being programmed to the HomeLink® system.
Make sure your hand-held transmitter is
programmed to activate the device you are trying
to program your HomeLink® button to.
Ensure that your vehicle is parked outside of the
garage before you begin programming.
It is recommended that you erase all the channels
of your HomeLink® before you use it for the first
time.
ERASING ALL THE HOMELINK®
C
HANNELS
To erase the channels, follow this procedure:

1. Place the ignition switch into the ON/RUN
position.

2. Push and hold the two outside HomeLink® buttons (I and III) for up to 20 seconds, or until
the HomeLink® indicator light flashes.
NOTE:Erasing all channels should only be performed
when programming HomeLink® for the first time.
Do not erase channels when programming addi -
tional buttons.
IDENTIFYING WHETHER YOU HAVE A
R
OLLING CODE OR NON-ROLLING CODE
D
EVICE
Before programming a device to one of your
HomeLink® buttons, you must determine whether
the device has a rolling code or non-rolling code. Rolling Code Devices
To determine if your device has a rolling code, a
good indicator is its manufacturing date. Typically,
devices manufactured after 1995 have rolling
codes. A device with a rolling code will also have a
“LEARN” or “TRAIN” button located where the
antenna is attached to the device. The button may
not be immediately visible when looking at the
device. The name and color of the button may vary
slightly by manufacturer.
NOTE:The “LEARN” or “TRAIN” button is not the button
you normally use to operate the device.
Non-rolling Code Devices
Most devices manufactured before 1995 will not
have a rolling code. These devices will also not
have a “LEARN” or “TRAIN” button.

What to do when an electrical load reduction
action message is present (“Battery Saver On” or
“Battery Saver Mode”)
During a trip:
Reduce power to unnecessary loads if possible:
Turn off redundant lights (interior or exte -
rior)
Check what may be plugged in to power
outlets +12 Volts, 115 Volts AC, USB ports
Check HVAC settings (blower, temperature)
Check the audio settings (volume)
After a trip:
Check if any aftermarket equipment was
installed (additional lights, upfitter electrical
accessories, audio systems, alarms) and review
specifications if any (load and Ignition Off Draw
currents).
Evaluate the latest driving cycles (distance,
driving time and parking time).
The vehicle should have service performed if
the message is still present during consecutive
trips and the evaluation of the vehicle and
driving pattern did not help to identify the cause.
WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the
instrument panel together with a dedicated
message and/or acoustic signal when applicable.
These indications are indicative and precautionary
and as such must not be considered as exhaustive
and/or alternative to the information contained in
the Owner’s Manual, which you are advised to read
carefully in all cases. Always refer to the
information in this chapter in the event of a failure
indication. All active telltales will display first if
applicable. The system check menu may appear
different based upon equipment options and
current vehicle status. Some telltales are optional
and may not appear.
RED WARNING LIGHTS
Air Bag Warning Light
This warning light will illuminate to
indicate a fault with the air bag, and will
turn on for four to eight seconds as a bulb
check when the ignition is placed in the
ON/RUN or ACC/ON/RUN position. This light will
illuminate with a single chime when a fault with the
air bag has been detected, it will stay on until the
fault is cleared. If the light is either not on during
startup, stays on, or turns on while driving, have
the system inspected at an authorized dealer as
soon as possible.
Brake Warning Light
This warning light monitors various brake
functions, including brake fluid level and
parking brake application. If the brake
light turns on it may indicate that the
parking brake is applied, that the brake fluid level
is low, or that there is a problem with the Anti-Lock
Brake System reservoir.
If the light remains on when the parking brake has
been disengaged, and the fluid level is at the full
mark on the master cylinder reservoir, it indicates
a possible brake hydraulic system malfunction or
that a problem with the Brake Booster has been
detected by the Anti-Lock Brake System (ABS) /
Electronic Stability Control (ESC) system. In this
case, the light will remain on until the condition has
been corrected. If the problem is related to the
brake booster, the ABS pump will run when
applying the brake, and a brake pedal pulsation
may be felt during each stop.
The dual brake system provides a reserve braking
capacity in the event of a failure to a portion of the
hydraulic system. A leak in either half of the dual
brake system is indicated by the Brake Warning
Light, which will turn on when the brake fluid level
in the master cylinder has dropped below a
specified level.
The light will remain on until the cause is corrected.

Light
This warning light monitors the ABS. The
light will turn on when the ignition is
placed in the ON/RUN or ACC/ON/RUN
position and may stay on for as long as
four seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the brake
system is not functioning and service is required as
soon as possible. However, the conventional brake
system will continue to operate normally,
assuming the Brake Warning Light is not also on. If the ABS light does not turn on when the ignition
is placed in the ON/RUN or ACC/ON/RUN position,
have the brake system inspected by an authorized
dealer.
Electronic Stability Control (ESC) Active
Warning Light — If Equipped
This warning light will indicate when the
ESC system is Active. The ESC Indicator
Light in the instrument cluster will come
on when the ignition is placed in the ON/
RUN or ACC/ON/RUN position, and when ESC is
activated. It should go out with the engine running.
If the ESC Indicator Light comes on continuously
with the engine running, a malfunction has been
detected in the ESC system. If this warning light
remains on after several ignition cycles, and the
vehicle has been driven several miles (kilometers)
at speeds greater than 30 mph (48 km/h), see an
authorized dealer as soon as possible to have the
problem diagnosed and corrected.
The ESC OFF Indicator Light and the ESC Indi -
cator Light come on momentarily each time the
ignition is placed in the ON/RUN or ACC/ON/
RUN position.
The ESC system will make buzzing or clicking
sounds when it is active. This is normal; the
sounds will stop when ESC becomes inactive.
This light will come on when the vehicle is in an
ESC event.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is
illuminated you could cause the fluid to boil over,
come in contact with hot engine or exhaust
components and cause a fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated will
eventually cause severe transmission damage
or transmission failure.
