8 KEYS, DOORS, AND WINDOWS
The key, inside the Remote Keyless
Entry (RKE) transmitter, is used for
the driver door and glove box.
To remove the key, press the button
near the bottom of the transmitter,
and pull the key out. Never pull the
key out without pressing the button.
If it becomes difficult to turn the key,
inspect the key blade for debris.
See your dealer if a new key is needed.
Contact Roadside Service if locked out
of the vehicle. SeeRoadside Service
0 353.
With an active OnStar or connected
service plan, an OnStar Advisor may
remotely unlock the vehicle. See
OnStar Overview 0363.
Remote Keyless Entry
(RKE) System
See Radio Frequency Statement 0359.
If there is a decrease in the key
operating range:
. Check the distance. The key may
be too far from the vehicle.
. Check the location. Other vehicles
or objects may be blocking the
signal. .
Check the key battery. See “Battery
Replacement ”later in this section.
. If the key is still not working
correctly, see your dealer or a
qualified technician for service.
Remote Keyless Entry
(RKE) System Operation
The Keyless Access system allows for
vehicle entry when the Remote
Keyless Entry (RKE) transmitter is
within 1 m (3 ft). See “Keyless Access
Operation ”following.
The RKE transmitter functions may
work up to 60 m (197 ft) away from
the vehicle.
Other conditions can impact the
performance of the transmitter. See
Remote Keyless Entry (RKE) System
0 8.

KEYS, DOORS, AND WINDOWS 23
Press any liftgate button, the touch
pad, or
bon the RKE transmitter
while the liftgate is moving to stop it.
Pressing any liftgate button or
pressing
btwice quickly on the RKE
transmitter again restarts the
operation in the reverse direction.
Pressing the touch pad on the liftgate
handle will restart the motion, but
only in the opening direction.
Caution
Manually forcing the liftgate to
open or close during a power cycle
can damage the vehicle. Allow the
power cycle to complete.
The power liftgate may be temporarily
disabled under extreme low
temperatures, or after repeated power
cycling over a short period of time.
If this occurs, the liftgate can still be
operated manually.
If the vehicle is shifted out of P (Park)
while the power function is in
progress, the liftgate will continue to
completion. If the vehicle is accelerated before the liftgate has
completed moving, the liftgate may
stop or reverse direction. Check for
Driver Information Center (DIC)
messages and make sure the liftgate is
closed and latched before driving.
Falling Liftgate Detection
If the power liftgate automatically
closes after a power opening cycle, it
indicates that the system is reacting
to excess weight on the 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 operation 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.

KEYS, DOORS, AND WINDOWS 31
Steering Column Lock
If equipped, the steering column lock
is a theft-deterrent device. This
feature locks the steering column
when the vehicle is turned off and the
driver door is opened, or when the
driver door is opened and then the
vehicle is turned off. The steering
column unlocks when the vehicle is
turned on.
The Driver Information Center (DIC)
may display one of these messages:
.A message to service the steering
column lock indicates that an
issue has been detected with the
column lock feature and the
vehicle should be serviced.
. A message that the steering
column is locked indicates that
the engine is running, but the
steering column is still locked. It is
normal for the column to be
locked during a remote start, but
the column should unlock after
the brake pedal is pressed and the
vehicle is started. No message will
display during a remote start. .
A message that the steering wheel
must be turned and the vehicle
must be started again indicates
that the column lock mechanism
is bound, the column locking
device was unable to unlock the
steering column, and the vehicle
did not start. If this happens,
immediately turn the steering
wheel from side to side to unbind
the column lock. If this does not
unlock the steering column, turn
the vehicle off and open the driver
door to reset the system. Then
turn the vehicle on and
immediately turn the steering
wheel side to side for about
15 seconds. In some cases, it may
take significant force to unbind
the column.
To keep the steering column from
binding, straighten the front wheels
before turning off the vehicle.
Immobilizer
See Radio Frequency Statement 0359.
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 vehicle is
turned off.
The immobilization system is
disarmed when the ignition is on or in
ACC/ACCESSORY and a valid
transmitter is present in the vehicle.
The security light, in the instrument
cluster, comes on if there is a problem
with arming or disarming the
theft-deterrent system.
The system has one or more RKE
transmitters matched to an
immobilizer control unit in your
vehicle. Only a correctly matched RKE

32 KEYS, DOORS, AND WINDOWS
transmitter will start the vehicle.
If the transmitter is ever damaged,
you may not be able to start your
vehicle.
When trying to start the vehicle, the
security light may come on briefly
when the ignition is turned on.
If the engine does not start and the
security light stays on, there is a
problem with the system. Turn the
ignition off and try again.
If the vehicle will not change ignition
modes (ACC/ACCESSORY, on, off), and
the RKE transmitter appears to be
undamaged, try another transmitter.
Or, you may try placing the
transmitter in the transmitter pocket
located in the center console. See
Remote Keyless Entry (RKE) System
Operation08.
If the ignition mode will not change
with the other transmitter or in the
transmitter pocket, your vehicle needs
service. If the ignition does change
modes, the first transmitter may be
faulty. See your dealer who can service the theft-deterrent system and have a
new RKE transmitter programmed to
the vehicle.
It is possible for the immobilizer
system to learn new or replacement
RKE transmitters. Up to eight
transmitters can be programmed for
the vehicle. To program additional
transmitters, see
“Programming
Transmitters to the Vehicle ”under
Remote Keyless Entry (RKE) System
Operation 08.
Do not leave the key or device that
disarms or deactivates the
theft-deterrent system in the vehicle.Exterior Mirrors
Convex Mirrors
{Warning
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you cut
too sharply into the right lane, you
could hit a vehicle on the right.
Check the inside mirror or glance
over your shoulder before changing
lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from the
driver seat.
