REMOTE CONTROL
Integrated Keyhead Transmitters
Your vehicle may be equipped with
two integrated keyhead
transmitters. The key blade is used
to start the vehicle and unlock or
lock the driver’s door from outside
the vehicle. The transmitter portion
functions as the remote control.
Note:Your vehicle’s keys were
issued with a security label that
provides important vehicle key cut
information. Keep the label in a safe
place for future reference.
Replacing the Battery
Note:Refer to local regulations when disposing of transmitter batteries.
Note:Do not wipe off any grease on the battery terminals or on the
back surface of the circuit board.
Note:Replacing the battery will not delete the transmitter from the
vehicle. The transmitter should operate normally.
The remote control uses one coin-type three-volt lithium battery CR2032
or equivalent.
Integrated Keyhead Transmitter
1. Twist a thin coin in the slot near the key
ring to remove the battery cover (1).
2. Carefully peel up the rubber gasket (2)
from the transmitter if it does not come off
with the battery cover.
3. Remove the old battery (3).

6. Snap the battery cover back onto the key.
Memory Feature
The feature allows the remote control to recall the driver seat, power
mirrors, steering column and power adjustable foot pedals memory
positions.

positions. If the easy entry and exit feature is enabled, the seat will move
to the easy entry position. The seat will move to the driver memory
position when the key is put in the ignition.
Programming Memory to the Transmitter
1. Move the memory features to the desired positions using the
associated controls.
2. Press and hold memory button1
(on the side of the driver’s seat) for
five seconds. A tone will sound after
about two seconds. Continue to hold
until a second tone is heard.
3. Within three seconds press the
lock button on the remote control.
4. Wait 10 seconds, then press the unlock button on the remote control.
Repeat this procedure for memory button2and a second remote control
if desired.
Deactivating Memory from the Transmitter
1. Press and hold the desired memory button for five seconds. A tone
will sound after about two seconds. Continue to hold until a second tone
is heard.

Opening and Closing the Power Liftgate
Note:The liftgate can be reversed with a second press on a control
button or transmitter and can be manually closed at any time.
The liftgate will only operate with your vehicle inP. The chime will beep
once if conditions are not correct to start an operation. These conditions
include:
•The ignition is in on and the transmission is not inP.
•The battery voltage is below the minimum operating voltage.
•The vehicle speed is at or above 3 mph (5 km/h).
If the liftgate reverses and starts to close after a open request, a fast
continuous chime indicates excessive load on the liftgate or a possible
strut failure. If any excessive load is removed and you still have a faster
chime, have the system serviced immediately by your authorized dealer.
Do not attempt to manually force the liftgate to travel faster than the
power system will permit. This will activate the obstacle detection
feature.
To open or close from the instrument panel:
Press the instrument panel button.
To open or close with the remote control:
Press the remote control button within three seconds.
To open with the outside liftgate
button (manual actuation):
1. Unlock the liftgate with the
remote entry transmitter or power
door unlock control.
2. Press the control button located
in the top of the liftgate pull cup
handle.
Note:Let the power system to
open the liftgate after releasing the
control button. Continued upward force after unlatching may activate the
obstacle detection feature and stop the power operation.
Note:If weight is added to the liftgate (bike rack, snow, etc.) it may
start a power close event immediately after a power open. If this
happens, a unique continuous chime will sound.

Obstacle Detection
Note:Entering your vehicle while the liftgate is closing can cause it to
bounce and activate obstacle detection. To prevent this, let the power
liftgate fully close before entering the vehicle.
The power liftgate system is equipped with an obstacle detection feature.
If the power liftgate is closing, the system is designed to reverse to full
open when it encounters a solid obstacle. A three second chime is also
sounded when an obstacle is detected. Once the obstacle is removed, the
liftgate can be closed under power.
If the power liftgate is opening, the system is designed to stop when it
encounters a solid obstacle. A chime will sound for three seconds while
the obstacle is present.
Resetting the Power Liftgate
If any of these conditions occur, the power liftgate may not operate and
must be reset:
•A low voltage or dead battery
•Disconnected battery
•The liftgate is manually closed and left ajar (unlatched)
To reset the power liftgate:
1. Disconnect the battery for 20 seconds then, reconnect the battery.
2. Manually close and fully latch the liftgate.
3. Power open the liftgate by using the remote entry transmitter or
instrument panel button.
Note:If the power liftgate system is turned off in the message center,
the system cannot be activated with the outside release handle or rear
cargo area control button. The system will need to be turned on to
resume operation with the outside release handle or rear cargo area
control button. The power liftgate is still operational through the use of
the remote entry transmitter and instrument panel button when the
power liftgate is turned off in the message center.
Liftgate Ajar Signal
If the liftgate or liftgate glass are not fully latched, you will receive a
message on the instrument panel. If you see this message, check both
the liftgate glass and liftgate door to ensure they are fully latched.

AUTOLAMPS
The autolamp system provides light
sensitive automatic on/off control of
the exterior lights normally
controlled by the headlamp control.
The autolamp system also keeps the
lights on for approximately
20 seconds or, if equipped with a
message center, you can select a
delay from 0–180 seconds after the
ignition switch is turned off. See
Message centerin theInstrument
Clusterchapter.
•To turn autolamps on, rotate the control counterclockwise one
position.
•To turn autolamps off, rotate the control to the off position.
INSTRUMENT LIGHTING DIMMER
Use to adjust the brightness of the
instrument panel when exterior
lights are on.
•Rotate the control from left to
right to brighten the instrument
panel.
•Rotate the control from right to
left to dim the instrument panel.
•Rotate the control fully to the right (past detent) to turn on interior
lamps.
•Rotate the control to the left position (past detent) to turn off the
interior lamps and to disable the illuminated entry feature. When the
control is in the far left position, it acts as a dome lamp
defeat/override.
Note:If the battery is disconnected, discharged, or a new battery is
installed, the instrument lighting dimmer requires re-calibration. Rotate
the control from the full dim position to the full dome/on position to
reset. This will ensure that your displays are visible under all lighting
conditions.
