Battery Replacement
{Warning
Never allow children to play with
the RKE transmitter. The
transmitter contains a small
battery, which can be a choking
hazard. If swallowed, internal
burns can occur, resulting in
severe injury or death. Seek
medical attention immediately if a
battery is swallowed.
Caution
When replacing the battery, do
not touch any of the circuitry on
the transmitter. Static from your
body could damage the
transmitter.
Caution
Always replace the battery with
the correct type. Replacing the
battery with an incorrect type
could potentially create a risk of
battery explosion. Dispose of
used batteries according to
instructions and local laws. Do
not attempt to burn, crush, or cut
the used battery, and avoid
exposing the battery to
environments with extremely low
air pressures or high
temperatures.
Replace the battery if the DIC
displays REPLACE BATTERY IN
REMOTE KEY.
The battery is not rechargeable. To
replace the battery: 1. Press the button on the rear of the transmitter and pull the key
out. Never remove the key
without pressing the button.
2. Remove the battery cover by prying it with a finger. 3. Remove the battery by pushing
on the battery and sliding it
toward the key blade.
4. Insert the new battery, positive side facing up. Push the
battery down until it is held in
place. Replace with a CR2032
or equivalent battery.
5. Snap the battery cover back on to the RKE transmitter.
6. Reinsert the key.
Remote Vehicle Start
If equipped, this feature allows the
engine to be started from outside
the vehicle.
/: This button will be on the RKE
transmitter if the vehicle has remote
start.
The climate control system will use
the previous settings during a
remote start. The rear defog may
come on during remote start based
on cold ambient conditions. The
rear fog indicator light does not
come on during remote start. If the
vehicle has heated and ventilated

To replace the cap:1. Position the bottom edge of the cap under the lower edge of
the metal piece (2). The
tabs (3) attach to the metal
piece (2) at the positions (1).
2. Rotate the cap upward and install into place.
3. Check that the cap is secure.
Free-Turning Locks
The door key lock cylinder turns
freely when either the wrong key is
used, or the correct key is not fully
inserted. The free-turning door lock
feature prevents the lock from being
forced open. To reset the lock, turn
it to the vertical position with the
correct key fully inserted. Remove
the key and insert it again. If this
does not reset the lock, turn the key
halfway around in the cylinder and
repeat the reset procedure.
Power Door Locks
K: Press to unlock the doors.
Q: Press to lock the doors. The
indicator light in the switch will
illuminate when activated.
Delayed Locking
This feature delays the locking of
the doors until five seconds after all
doors are closed.
Delayed locking can only be turned
on when Open Door Anti-Lockout
has been turned off. When
Qis pressed on the power
door lock switch while the door is
open, a chime will sound three
times indicating delayed locking is
active.
The doors will lock automatically
five seconds after all doors are
closed. If a door is reopened before
that time, the five-second timer will
reset when all doors are closed
again.
Press
Qon the door lock switch
again or press
Qon the RKE
transmitter to lock the doors
immediately.
This feature can also be
programmed. See Vehicle
Personalization 0138.

liftgate or a possible support strut
failure. A repetitive chime will sound
while the falling liftgate detection
feature is operating. Remove any
excess weight. If the liftgate
continues to automatically close
after opening, see your dealer for
service before using the power
liftgate.
Interfering with the power liftgate
motion or manually closing the
liftgate too quickly after power
opening may resemble a support
strut failure. This could also activate
the falling liftgate detection feature.
Allow the liftgate to complete its
operation and wait a few seconds
before manually closing the liftgate.
Obstacle Detection Features
If the liftgate encounters an obstacle
during a power open or close cycle,
the liftgate will automatically reverse
direction and move a short distance
away from the obstacle. After
removing the obstruction, the power
liftgate can be used again. If the
liftgate encounters multiple
obstacles on the same power cycle,the power function will deactivate.
After removing the obstructions,
manually close the liftgate. This will
allow normal power operation
functions to resume.
If the vehicle is locked while the
liftgate is closing, and an obstacle is
encountered that prevents the
liftgate from completely closing, the
horn will sound as an alert that the
liftgate did not close.
Pinch sensors are on the side
edges of the liftgate. If an object is
caught between the liftgate and the
vehicle and presses against a
sensor, the liftgate will reverse
direction and open fully. The liftgate
will remain open until it is activated
again or closed manually.Setting the 3/4 Mode
To change the position the liftgate
stops at when opening:
1. Select MAX or 3/4 mode and power open the liftgate. 2. Stop the liftgate movement at
the desired height by pressing
any liftgate switch. Manually
adjust the liftgate position if
needed.
3. Press and hold
|under the
open liftgate until the turn
signals flash and a beep
sounds. This indicates the
setting has been recorded.
The liftgate cannot be set below a
minimum programmable height.
If there is no light flash or sound,
then the height adjustment may be
too low.
Manual Operation
Select OFF to manually operate the
liftgate. See “Manual Liftgate” at the
beginning of this section.
Caution
Attempting to move the liftgate
too quickly and with excessive
force may result in damage to the
vehicle.

message will appear on the DIC.
Immobilizer
See Radio Frequency Statement
0 350.
Immobilizer Operation
This vehicle has a passive
theft-deterrent system. The system does not have to be
manually armed or disarmed.
The vehicle is automatically
immobilized when the transmitter
leaves the vehicle.
The immobilization system is
disarmed when ENGINE START/
STOP is pressed and a valid
transmitter is in the vehicle.
The security light in the instrument
cluster comes on when there is a
problem with arming or disarming
the theft-deterrent system.
The system has one or more
transmitters matched to an
immobilizer control unit in the
vehicle. Only a correctly matched
transmitter will start the vehicle.
If the transmitter is damaged, the
vehicle may not start.

undamaged, try another transmitter,
or place the transmitter in the
transmitter pocket. See“Starting the
Vehicle with a Low Transmitter
Battery” underRemote Keyless
