Closing
With one or more hands placed on the outside trunk
surface push the trunk lid down until you hear the trunk
lock latch into place.
NOTE:Before closing the trunk lid make sure your key fob
isn’t inside the trunk area. The trunk will latch then
automatically unlock if the key fob is sensed not allowing
the key fob to be locked in the trunk area.
Trunk Safety
Trunk Emergency Release
As a security measure, a trunk internal emergency release
lever is built into the trunk latching mechanism. In the
event of an individual being locked inside the trunk, the
trunk can be opened by actuating the glow-in-the-dark
handle attached to the trunk latching mechanism.
WARNING!
Do not allow children to have access to the trunk, either
by climbing into the trunk from outside, or through the
inside of the vehicle. Always close the trunk lid when
your vehicle is unattended. Once in the trunk, young
children may not be able to escape, even if they entered
through the rear seat. If trapped in the trunk, children
can die from suffocation or heat stroke.

GARAGE DOOR OPENER — IF EQUIPPED
HomeLink replaces up to three hand-held transmitters that
operate devices such as garage door openers, motorized
gates, lighting, or home security systems. The HomeLink
unit is powered by your vehicle’s battery.
The HomeLink buttons that are located in the overhead
console designate the three different HomeLink channels.
The HomeLink indicator is located on the left side of the
first button.
NOTE:HomeLink is disabled when the Vehicle Security
Alarm is active.
Before You Begin Programming HomeLink
Be sure that your vehicle is parked outside of the garage
before you begin programming.
For more efficient programming and accurate transmission
of the radio-frequency 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.
To erase the channels, place the ignition in the ON/RUN
position, and push and hold the two outside HomeLink
buttons (I and III) for up to 20 seconds or until the orange
indicator flashes.
NOTE:
• Erasing all channels should only be performed when
programming HomeLink for the first time. Do not erase
channels when programming additional buttons.
• If you have any problems, or require assistance, please
call toll-free 1-800-355-3515 or, on the Internet at
HomeLink.com for information or assistance.

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 trans-
mitter every two seconds until HomeLink has success-
fully 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 acti-
vate 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. Cycle the ignition to 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.

Troubleshooting Tips
If you are having trouble programming HomeLink, here
are some of the most common solutions:
•Replace the battery in the Garage Door Opener hand-
held transmitter.
• Push the LEARN button on the Garage Door Opener to
complete the training for a Rolling Code.
• Did you unplug the device for programming and
remember to plug it back in? If you have any problems, or require assistance, please call
toll-free 1-800-355-3515 or, on the Internet at
HomeLink.com for information or assistance.
WARNING!
•
Vehicle exhaust contains carbon monoxide, a danger-
ous gas. Do not run your vehicle in the garage while
programming the transceiver. Exhaust gas can cause
serious injury or death.
• Your motorized door or gate will open and close
while you are programming the universal trans-
ceiver. Do not program the transceiver if people, pets
or other objects are in the path of the door or gate.
Only use this transceiver with a garage door opener
that has a “stop and reverse” feature as required by
Federal safety standards. This includes most garage
door opener models manufactured after 1982. Do not
use a garage door opener without these safety fea-
tures. Call toll-free 1-800-355-3515 or, on the Internet
at HomeLink.com for safety information or assis-
tance.

•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
The warning/indicator lights will illuminate in the instru-
ment 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 infor-
mation 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 indica-
tion. All active telltales will display first if applicable. The
system check menu may appear different based upon
equipment options and current vehicle status. Some tell-
tales are optional and may not appear.
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 Restraint 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.

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 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
the transmission into NEUTRAL and idle the vehicle. 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 “In Case Of
Emergency” for further information.
— Battery Charge Warning Light
This light illuminates when the battery is not charging
properly. If it stays on while the engine is running, there
may be a malfunction with the charging system. Contact an
authorized dealer as soon as possible.
This indicates a possible problem with the electrical system
or a related component.
— Oil Pressure Warning Light
This warning light will illuminate to indicate low engine
oil pressure. If the light turns on while driving, stop the
vehicle, shut off the engine as soon as possible, and contact
an authorized dealer. A chime will sound when this light
turns on.
Do not operate the vehicle until the cause is corrected. This
light does not indicate how much oil is in the engine. The
engine oil level must be checked under the hood.
— Oil Temperature Warning Light
This warning light will illuminate to indicate the engine oil
temperature is high. If the light turns on while driving,
stop the vehicle and shut off the engine as soon as possible.

push the multifunction lever forward (toward the front of
the vehicle) to turn on the high beams. Pull the multifunc-
tion lever rearward (toward the rear of the vehicle) to turn
off the high beams. If the high beams are off, pull the lever
toward you for a temporary high beam on,flash to pass
scenario.
ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and transmission
control systems. When these systems are operating prop-
erly, your vehicle will provide excellent performance and
fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to assist your service technician in making repairs. Although your
vehicle will usually be drivable and not need towing, see
an authorized dealer for service as soon as possible.
CAUTION!
•
Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed.
• If the MIL is flashing while the vehicle is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
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.
