vehicle if it is driven with the
liftgate, trunk/hatch open, or with
any objects that pass through the
seal between the body and the
trunk/hatch or liftgate. Engine

If the vehicle must be driven with
the liftgate, or trunk/hatch open:
.Close all of the windows.
.Fully open the air outlets on
or under the instrument
panel.

The power liftgate has three modes
of operation. Mode selection is
controlled by the interior mode
switch.
Choose the power liftgate mode by
turning the dial on the switch until
the indicator lines up with the
desired position. The vehicle must
be in P (Park).The three modes are:
MAX :
The liftgate power opens to
the full open height.
3/4 : The liftgate power opens to a
reduced open 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: The liftgate only operates
manually in this position.
Manual operation of a liftgate that
also has power operation requires
more effort than with a standard
manual liftgate. In either the MAX or the 3/4 mode,
the liftgate can be power opened
and closed by:
.First pressingKand then
pressing and holding
Von the
Remote Keyless Entry (RKE)
transmitter until the liftgate starts
moving. See Remote Keyless
Entry (RKE) System Operation
on page 1‑3.
.Pressing the power liftgate
button on the center of the mode
switch, located on the overhead
console.
.Pressing the touchpad switch on
the liftgate outside handle to
open the liftgate.

Press and release&on the
liftgate adjacent to the latch to close
the liftgate.
Pressing any button, or the
touchpad switch while the liftgate is
moving stops it. Pressing the button
or RKE switch again reverses the
direction. The touch pad switch will
stop the liftgate from moving. 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. Do not force the liftgate open or
closed during a power cycle.
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 you shift the transmission out of
P (Park) while the power function is
in progress, the liftgate power
function will continue to completion.
If you shift the transmission out of
P (Park) and accelerate before the
power liftgate latch is closed, the
liftgate may reverse to the open
position. Cargo could fall out of the
vehicle. Always make sure the
power liftgate is closed and latched
before you drive away.
If you power open the liftgate and
the liftgate support struts have lost
pressure, the turn signals flash and
a chime sounds. The liftgate stays
open temporarily, then slowly
closes. See your dealer/retailer for
service before using the 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 to the full closed or open
position. 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.
The
“Manually Close Power Liftgate”
warning message in the Driver
Information Center (DIC) will
display. After removing the
obstructions, the liftgate will resume
normal power operation.
Your vehicle has pinch sensors
located on the side edges of the
liftgate. If an object is caught
between the liftgate and the body
and presses against this sensor, the
liftgate will reverse direction and
open fully. The liftgate will remain
open until it is activated again or
closed manually.

liftgate must already be open for the
system to hold it open. The liftgate
cannot be set to stop below that
minimum.
Manual Operation of Power
Liftgate
To change the liftgate to manual
operation, turn the mode switch to
the OFF position.
With the power liftgate disabled and
all of the doors unlocked, the liftgate

outside of the liftgate, and lift the
gate open. To close the liftgate, use
the pull cup to lower the liftgate and
close. With the power liftgate

made with the striker. Always close
the liftgate before driving. If the RKE button is pressed while
power operation is disabled, the turn
signals flash and the liftgate will
not move.

has low voltage, the liftgate will not
open. The liftgate will resume
operation when the battery is
reconnected and charged.

instrument panel cluster, comes on
if there is a problem with arming or
disarming the theft-deterrent
system.

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.
