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 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. 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. 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
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 stop at a partially open
position. 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.

Vehicle Alarm System
The indicator light, on the
instrument panel near the
windshield, indicates the status of
the system.
Off : Alarm system is disarmed.
On Solid : Vehicle is secured
during the delay to arm the system.
Fast Flash : Vehicle is unsecured.
A door, liftgate, or the hood is open.
Slow Flash : Alarm system is
armed.
Arming the Alarm System
1. Turn off the vehicle.
2. Lock the vehicle in one of three ways:
.Use the RKE transmitter.
. Use the Keyless Access
system.
. With a door open, press
Q
on the interior of the door.
3. After 30 seconds the alarm system will arm, and the
indicator light will begin to
slowly flash. Pressing
Qon the
RKE transmitter a second time
will bypass the 30-second
delay and immediately arm the
alarm system.
The vehicle alarm system will not
arm if the doors are locked with
the key.
If the driver door is opened without
first unlocking with the RKE
transmitter, the horn will chirp and
the lights will flash to indicate
pre-alarm. If the vehicle is not
started, or the door is not unlocked

52 Keys, Doors, and Windows
by pressingKon the RKE
transmitter during the 10-second
pre-alarm, the alarm will be
activated.
The alarm will also be activated if a
passenger door, the liftgate, or the
hood is opened without first
disarming the system. When the
alarm is activated, the turn signals
flash and the horn sounds for about
30 seconds. The alarm system will
then re-arm to monitor for the next
unauthorized event.
Disarming the Alarm System
To disarm the alarm system or turn
off the alarm if it has been activated:
. Press
Kon the RKE transmitter.
. Unlock the vehicle using the
Keyless Access system.
. Start the vehicle.
To avoid setting off the alarm by
accident:
. Lock the vehicle after all
occupants have exited. .
Always unlock a door with the
RKE transmitter, or use the
Keyless Access system.
Unlocking the driver door with
the key will not disarm the
system or turn off the alarm.
How to Detect a Tamper
Condition
IfKis pressed on the RKE
transmitter and the horn chirps three
times, an alarm occurred previously
while the alarm system was armed.
If the alarm has been activated, a
message will appear on the DIC.
Power Sounder, Inclination
Sensor, and Intrusion Sensor
In addition to the standard
theft-deterrent system features, this
system may also have a power
sounder, inclination sensor, and
intrusion sensor.
The power sounder provides an
audible alarm which is distinct from
the vehicle’ s horn. It has its own power source, and can sound an
alarm if the vehicle’s battery is
compromised.
The inclination sensor can set off
the alarm if it senses movement of
the vehicle, such as a change in
vehicle orientation.
The intrusion sensor monitors the
vehicle interior, and can activate the
alarm if it senses unauthorized entry
into the vehicle’s interior. Do not
allow passengers or pets to remain
in the vehicle when the intrusion
sensor is activated.
Before arming the theft-deterrent
system and activating the intrusion
sensor:
.
Make sure all doors and
windows are completely closed.
. Secure any loose items such as
a sunshades.
. Make sure there are no
obstructions blocking the
sensors in the front overhead
console.
. Close DVD screens before
leaving the vehicle.

336 Vehicle Care
When the recommended
pressure is reached, the horn
sounds once and the turn
signal lamp will stop flashing
and briefly turn solid.
Repeat these steps for all
underinflated tires that have
illuminated the low tire pressure
warning light.
If the tire is overinflated by more
than 35 kPa (5 psi), the horn will
sound multiple times and the turn
signal lamp will continue to flash for
eight seconds after filling stops. To
release and correct the pressure,
while the turn signal lamp is still
flashing, briefly press the center of
the valve stem. When the
recommended pressure is reached,
the horn sounds once.
If the turn signal lamp does not flash
within 15 seconds after starting to
inflate the tire, the tire fill alert has
not been activated or is not working.
If the hazard warning flashers are
on, the tire fill alert visual feedback
will not work properly. The TPMS will not activate the tire
fill alert properly under the following
conditions:
.
There is interference from an
external device or transmitter.
. The air pressure from the
inflation device is not sufficient
to inflate the tire.
. There is a malfunction in
the TPMS.
. There is a malfunction in the
horn or turn signal lamps.
. The identification code of the
TPMS sensor is not registered to
the system.
. The battery of the TPMS sensor
is low.
If the tire fill alert does not operate
due to TPMS interference, move the
vehicle about 1 m (3 ft) back or
forward and try again. If the tire fill
alert feature is not working, use a
tire pressure gauge.TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a new
tire/wheel position after rotating the
vehicle’s tires or replacing one or
more of the TPMS sensors. Also,
the TPMS sensor matching process
should be performed after replacing
a spare tire with a road tire
containing the TPMS sensor. The
malfunction light and the DIC
message should go off at the next
ignition cycle. The sensors are
matched to the tire/wheel positions,
using a TPMS relearn tool, in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear.
See your dealer for service or to
purchase a relearn tool. A TPMS
relearn tool can also be purchased.
