If equipped, the power liftgate
switch is on the overhead console.
The vehicle must be in P (Park) to
operate. The taillamps flash when
the power liftgate moves.
The three modes are:
MAX :Opens to maximum height.
3/4 : Opens to a reduced height
that can be set by the vehicle
operator. Use this setting to prevent
the liftgate from opening into
overhead obstructions such as a
garage door or roof mounted cargo
during power operation. The liftgate
can still be fully opened manually. OFF :
Opens manually only.
Manual operation of a liftgate that
also has power operation requires
more effort than a standard manual
liftgate.
To open or close the liftgate, select
MAX or 3/4 mode and then:
. Press and hold
Yon the RKE
transmitter until the liftgate starts
moving. See Remote Keyless
Entry (RKE) System
Operation 027.

the driver door unlocked.
Press and release8on the
liftgate next to the latch to close the
liftgate.
Press any liftgate switch or the
touch pad while the liftgate is
moving to stop it. Pressing again
restarts the motion. There is a
minimum distance that the power
liftgate must already be open for the
system to hold it open. If movement
is stopped below that minimum, the
liftgate closes.
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
temperatures or low battery
conditions. 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
The power liftgate will automatically
close if the support strut has lost
pressure. 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,
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 located on the
side edges of the liftgate. If an
object is caught between the liftgate
and the vehicle and presses against
this sensor, the liftgate will reverse
direction and stop at the first
position at which the liftgate can
hold open. 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 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
8on the
liftgate next to the latch until
the turn signals flash and a
beep sounds to indicate that
the new setting is recorded.
When power opened with the 3/4
mode selected, the liftgate stops at
the new set position.
If there is no audible and visual
feedback when setting the
intermediate stop position, the
liftgate height is being set below the
3/4 open height minimum
(approximately 1.5 m or 5 ft). The
liftgate cannot be set below that
minimum and the new setting will
not be recorded.

too quickly and with excessive
force may result in damage to the
vehicle.

pad under the liftgate handle and lift
up. To close the liftgate, use the pull
cup to lower the liftgate and close.
With the power liftgate disabled, the

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 key is
removed from the ignition.
The system is automatically
disarmed when the vehicle is
started with the correct key. The key
uses a transponder that matches an
immobilizer control unit in the
vehicle and automatically disarms
the system. Only an authorized key
starts the vehicle. The vehicle may
not start if the key is damaged.
The security light in the instrument
cluster comes on if there is a
problem with arming or disarming
the theft-deterrent system.When trying to start the vehicle, the
security light comes 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 engine still does not start, and
the key appears to be undamaged
or the light continues to stay on, try
another ignition key. If the engine
does not start with the other key, the
vehicle needs service. If the vehicle
does start, the first key may be
damaged. See your dealer who can
service the theft-deterrent system
and have a new key made.
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.
