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
and a message will display in the
Driver Information Center (DIC).
SeeObject Detection System
Messages on page 5-38. After
removing the obstructions, the
liftgate will resume normal power
operation.
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 open fully. The liftgate
will remain open until it is activated
again or closed manually.
Manual Operation of Power
Liftgate
To change the liftgate to manual
operation, press OFF on the liftgate
switch.
With the power liftgate disabled and
all of the doors unlocked, the liftgate
can be manually opened and
closed.
To open the liftgate, press the touch
pad on the handle (B) and lift up.
Use the pull cup to lower and close
the liftgate. Do not press the touch
pad while closing the liftgate. This
will cause the liftgate to be
unlatched. The liftgate latch will
power close. Always close the
liftgate before driving.
If
8on the RKE transmitter or
lon the liftgate is pressed while
power operation is disabled, the
lamps will flash three times, but the
liftgate will not move.
It is not recommended to drive with
the liftgate open, however, when
driving with the liftgate open; the liftgate should be set to manual
operation by pressing OFF on the
liftgate switch on the center console.
The liftgate has an electric latch.
If the battery is disconnected or has
low voltage, the liftgate will not
open. The liftgate will resume
operation when the battery is
reconnected and charged.

2. Lock the door with the RemoteKeyless Entry (RKE) transmitter
or the power door lock switch.
The security light will come on to
inform the driver the system is
arming. If a door is open when
the doors are locked, the
security light will flash.
If the delayed locking feature is
turned on, the theft-deterrent
system will not start the arming
process until the last door is
closed and the delay timer has
expired. See Delayed Locking
on page 2-8.
3. Close all doors. The security light should go off after about
30 seconds. The alarm is not
armed until the security light
goes off.
If a locked driver door is opened
without using the RKE transmitter, a
10-second pre-alarm will occur. The
horn will chirp and the lights will
flash. If the key is not placed in the
ignition and turned to START or the
door is not unlocked by pressing the unlock button on the RKE
transmitter during the 10-second
pre-alarm, the alarm will go off. Your
vehicle's headlamps will flash and
the horn will sound for about
30 seconds, then will turn off to save
the battery power.
The theft-deterrent system will not
activate if the doors are locked with
the vehicle's key or the manual door
lock. It activates only if you use the
power door lock switch with the door
open or the RKE transmitter. You
should also remember that you can
start your vehicle with the correct
ignition key if the alarm has been
set off.
To avoid setting off the alarm by
accident:
.If you do not want to activate the
theft-deterrent system, the
vehicle should be locked with
the door key after the doors are
closed.
.Always unlock the doors with the
RKE transmitter. Unlocking a
door any other way will set off
the alarm if it is armed.
If you set off the alarm by accident,
press unlock on the RKE transmitter
or place the key in the ignition and
turn it to START to turn off the
alarm. The alarm will not stop if you
try to unlock a door any other way.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, lower the driver window and open the
driver door.
2. Activate the system by locking the doors with the power door
lock switch while the door is
open, or with the RKE
transmitter.
3. Get out of the vehicle, close the door and wait for the security
light to go out.

manual door lock and open the
door. This should set off the
alarm.

door unlock switch will not work.
If the alarm does not sound when it
should but the headlamps flash,
check to see if the horn works. The
horn fuse may be blown. To replace
the fuse, see Fuses and Circuit
Breakers on page 10-32.
If the alarm does not sound or the
headlamps do not flash, the vehicle
should be serviced by your dealer.
Immobilizer
See Radio Frequency Statement on
page 13-15.
Immobilizer Operation
This vehicle has PASS-Key®III+
(Personalized Automotive Security
System) theft-deterrent system.
PASS-Key III+ is a passive
theft-deterrent system.
The system is automatically armed
when the key is removed from the
ignition.
The system is automatically
disarmed when the key is turned to
ON/RUN, ACC/ACCESSORY,
or START from the LOCK/OFF
position.
You do not have to manually arm or
disarm the system.
The security light will come on if
there is a problem with arming or
disarming the theft-deterrent
system.
When the PASS-Key III+ system
senses that someone is using the
wrong key, it prevents the vehicle
from starting. Anyone using a
trial-and-error method to start the vehicle will be discouraged because
of the high number of electrical key
codes.
If the engine does not start and the
security light on the instrument
panel cluster comes on when trying
to start the vehicle, there may be a
problem with the theft-deterrent
system. Turn the ignition off and try
again.
If the engine still does not start, and
the key appears to be undamaged,
try another ignition key. At this time,
you may also want to check the
fuse. See
Fuses and Circuit
Breakers on page 10-32. If the
engine still does not start with the
other key, the vehicle needs service.
If the vehicle does start, the first key
may be faulty. See your dealer who
can service the PASS-Key III+ to
have a new key made.
It is possible for the PASS-Key III+
decoder to learn the transponder
value of a new or replacement key.
Up to 10 keys may be programmed
for the vehicle. The following

procedure is for programming
additional keys only. If all the
currently programmed keys are lost
or do not operate, you must see
your dealer or a locksmith who can
service PASS-Key III+ to have keys
made and programmed to the
system.
See your dealer or a locksmith who
can service PASS-Key III+ to get a
new key blank cut exactly as the
ignition key that operates the
system.
To program the new additional key:
1. Verify that the new key has a
1
stamped on it.
2. Insert the original, already programmed key in the ignition
and start the engine. If the
engine will not start, see your
dealer for service.
3. After the engine has started, turn the key to LOCK/OFF, and
remove the key. 4. Insert the new key to be
programmed and turn it to the
ON/RUN position within
five seconds of turning the
ignition to the LOCK/OFF
position in Step 3.
The security light will turn off
once the key has been
programmed.
5. Repeat Steps 1 through 4 if additional keys are to be
programmed.
If you lose or damage your
PASS-Key III+ key, see your dealer
or a locksmith who can service
PASS-Key III+ to 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.
