5. Push and hold the programmed HomeLink button. Theinstrument cluster display will display “CHANNEL #
TRANSMIT.” If the device is plugged in and activates,
programming is complete.
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. Turn the ignition switch to the ON/RUN position.
NOTE: For vehicle’s equipped with Keyless Enter-N-Go,
place the ignition in the RUN position with the Engine ON.
For vehicle’s equipped with Keyless Enter-N-Go, place the
ignition in the RUN position with the Engine ON. Make
sure while programming HomeLink with the engine ON
that your vehicle is outside of your garage, or that the
garage door remains open at all times.
2. Push and hold the desired HomeLink button until the instrument cluster display shows “CHANNEL #
TRAINING” 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.
Security
It is advised to erase all channels before you sell or turn in
your vehicle.
To erase the channels press and hold the two outside
HomeLink buttons (I and III) for up 20 seconds. The
instrument cluster display will display “CLEARING
CHANNELS.” Release the buttons when the instrument
cluster display shows “CHANNELS CLEARED.”
The HomeLink Universal Transceiver is disabled when the
Vehicle Security Alarm is active.

•Evaluate the latest driving cycles (distance, driving time
and parking time).
• The vehicle should have service performed if the mes-
sage 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
Red Warning Lights
— Seat Belt Reminder Warning Light
This light indicates when the driver or passenger seat belt
is unbuckled. When the ignition is first placed in the
ON/RUN or ACC/ON/RUN position and if the driver ’s
seat belt is unbuckled, a chime will sound and the light will
turn on. When driving, if the driver or front passenger seat
belt remains unbuckled, the Seat Belt Reminder Light will
flash or remain on continuously and a chime will sound.
Refer to “Occupant Restraints Systems” in “Safety” for
further information.
— Air Bag Warning Light
This light indicates 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 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.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level conditions.
The vehicle should have service performed, and the brake
fluid level checked.
If brake failure is indicated, immediate repair is necessary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed. It
will take longer to stop the vehicle. You could have a
collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System (ABS)
are also equipped with Electronic Brake Force Distribution
(EBD). In the event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light. Immediate
repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by your authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake application.
— Vehicle Security Warning Light — If Equipped
This light will flash at a fast rate for approximately 15
seconds when the vehicle security alarm is arming, and
then will flash slowly until the vehicle is disarmed.
— Engine Coolant Temperature Warning Light
This light warns of an overheated engine condition. If the
engine coolant temperature is too high, this indicator will
illuminate and a single chime will sound. If the tempera-
ture reaches the upper limit, a continuous chime will be
sound for four minutes or until the engine is able to cool:
whichever comes first.
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

Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to ac-
cess this information to assist with the diagnosis and
service of your vehicle and emissions system.
WARNING!
•ONLY an authorized service technician should con-
nect equipment to the OBD II connection port in
order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the OBD
II connection port, such as a driver-behavior tracking
device, it may:
• Be possible that vehicle systems, including safety
related systems, could be impaired or a loss of
vehicle control could occur that may result in an
accident involving serious injury or death.
• Access, or allow others to access, information
stored in your vehicle systems, including personal
information.
For further information, refer to “Cybersecurity” in “Mul-
timedia”.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass an
inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration. For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not on
when the engine is running, and that the OBD II system is
ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may notbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not ready
for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle’s OBD II system is ready, you must do the follow-
ing:
1. Cycle the ignition switch to the ON position, but do not crank or start the engine.
NOTE: If you crank or start the engine, you will have to
start this test over.
