2-4 Keys, Doors, and Windows
Programming without a
Recognized Key (Key
Vehicles Only)
Program a new key to the vehicle
when a recognized key is not
available. Canadian regulations
require that Canadian owners see
their dealer.
If there are no currently recognized
keys available, follow this procedure
to program the first key.
This procedure will take
approximately 30 minutes to
complete for the first key. The
vehicle must be off and all of the
keys must be with you.
1. Insert the new vehicle key intothe ignition.
2. Turn to ON/RUN. The security light will come on.
3. Wait 10 minutes until the security light turns off.
4. Turn the ignition to LOCK/OFF. 5. Repeat Steps 2–4 two more
times. After the third time, turn to
ON/RUN; the key is learned and
all previously known keys will no
longer work with the vehicle.
Remaining keys can be learned by
following the procedure in
“Programming with a Recognized
Key (Key Vehicles Only).”
The key has a bar-coded key tag
that the dealer or qualified locksmith
can use to make new keys. Store
this information in a safe place, not
in the vehicle.
See your dealer if a replacement
key or additional key is needed.
If it becomes difficult to turn a key,
inspect the key blade for debris.
Periodically clean with a brush
or pick.
With an active OnStar subscription,
an OnStar Advisor may remotely
unlock the vehicle. See OnStar
Overview on page 14-1.Remote Keyless Entry
(RKE) System
See Radio Frequency Statement on
page 13-12.
If there is a decrease in the RKE
operating range:
.Check the distance. The
transmitter may be too far from
the vehicle.
.Check the location. Other
vehicles or objects may be
blocking the signal.
.Check the transmitter's battery.
See “Battery Replacement” later
in this section.
.If the transmitter is still not
working correctly, see your
dealer or a qualified technician
for service.

restarts the operation in the reverse
direction. The touch pad on the
liftgate handle cannot be used to
close the liftgate.
Do not manually force the liftgate to
open or close during a power cycle.
The power liftgate may be
temporarily disabled in extremely
low temperatures, or after repeated
power cycling over a short period of
time. If this occurs, the liftgate can
still be operated manually. Select
OFF on the liftgate switch.
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. Make sure
the liftgate is closed and latched
before driving.
If the power liftgate support strut
has lost pressure, the turn signals
will flash and a chime will soundwhile the liftgate automatically
closes. See your dealer for service
before using the power liftgate.
Obstacle Detection Features
If the liftgate encounters an obstacle
during a power open or close cycle,
a warning chime will sound and 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, which
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
8next to the
latch on the outside of the
liftgate until the turn signals flash
and a beep sounds. This
indicates the setting has been
recorded.

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.
