disconnected or has low voltage, the liftgate
will not open. The liftgate will resume operation
when the battery is reconnected and charged.
If the battery is properly connected and has
adequate voltage, and the liftgate still will not
function, your vehicle should be taken to a
dealership for service.

Power Liftgate Operation
{CAUTION:
It can be dangerous to drive with the
liftgate open because carbon monoxide
(CO) gas can come into your vehicle. You
cannot see or smell CO. It can cause
unconsciousness and even death.
CAUTION: (Continued)
CAUTION: (Continued)
If you must drive with the liftgate open, or
if electrical wiring or other cable
connections must pass through the seal
between the body and the liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
with the recirculation mode off. That
will force outside air into your vehicle.
SeeClimate Control System on
page 199.
If you have air outlets on or under
the instrument panel, open them all
the way.
If your vehicle has a power liftgate,
disable the power liftgate function.
SeePower Liftgate on page 110.
Your vehicle may have a power liftgate. The
vehicle must be in PARK (P) to use the power
feature.
110

The liftgate can also be closed by pressing the
power liftgate button next to the liftgate latch. Press
the button a second time during liftgate operation to
reverse that operation.
The power liftgate may be temporarily disabled
under extreme temperatures, or under low battery
conditions. If this occurs, the liftgate can still be
operated manually.
If you shift the transmission out of PARK (P) while
the power function is in progress, the liftgate power
function will continue to completion. If you shift the
transmission out of PARK (P) and accelerate beforethe power liftgate latches 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 lights will
ash and a chime will sound. The liftgate will stay
open temporarily, then slowly close. 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, and you must manually
open or close the liftgate. The LIFTGATE OPEN
warning message in the Driver Information Center
(DIC) will indicate that the liftgate is open. After
removing the obstructions, manually open the
liftgate to the full open position or close the liftgate
to the fully closed and latched position. The liftgate
will now 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.
Do not force the liftgate open or closed during
a power cycle.
Manual Operation of Power Liftgate
To change the liftgate to
manual operation,
toggle the switch on the
center console to the
disable position
indicated by a circle.
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 touchpad on the
handle on the outside of the liftgate, and lift
the gate open. To close the liftgate, use the pull
cup or pull strap to lower the liftgate and close.
The liftgate latch will power close. Always close the
liftgate before driving.
If the RKE button or the power close button on the
liftgate is pressed while power operation is
disabled, the lights will ash three times, but the
liftgate will not move.
It is not recommended that you drive with the
liftgate open, however, if you must drive with the
liftgate open, the liftgate should be set to manual
operation — the center console switch set to the
disable position.
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.
If the battery is properly connected with adequate
voltage, the switch is not disabled, and the liftgate
still will not function, your vehicle should be taken to
a dealer/retailer for service.

Testing the Alarm
To test the alarm:
1. From inside the vehicle, lower the driver’s
window and open the driver’s door.
2. Activate the system by locking the doors with
the RKE transmitter.
3. Get out of the vehicle, close the door and wait
for the security light to go out.
4. Then reach in through the window, unlock the
door with the manual door lock and open the
door. This should set off the alarm.
If the alarm does not sound when it should, but the
vehicle’s headlamps ash, check to see if the horn
works. The horn fuse may be blown. To replace the
fuse, seeFuses and Circuit Breakers on page 490.
If the alarm does not sound or the vehicle’s
headlamps do not ash, see your dealer/retailer for
service.

Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.
PASS-Key
®III+ uses a radio frequency
transponder in the key that matches a decoder in
your vehicle.
PASS-Key®III+ Operation
Your vehicle has PASS-Key®III+ (Personalized
Automotive Security System) theft-deterrent
system. PASS-Key
®III+ is a passive
theft-deterrent system. This means you do not
have to do anything special to arm or disarm the
system. It works when you transition the key
to ON, ACCESSORY or START from the OFF
position.
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 comes on when trying
to start the vehicle, the key may have a damaged
transponder. 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, seeFuses and Circuit Breakers on
page 490. If the engine still does not start with the
other key, your vehicle needs service. If your
vehicle does start, the rst key may be faulty. See
your dealer/retailer who can service the
PASS-Key
®III+ to have a new key made. In an
emergency, contact Roadside Assistance.
It is possible for the PASS-Key
®III+ decoder to
learn the transponder value of a new or
replacement key. Up to nine additional 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/retailer or a
locksmith who can service PASS-Key
®III+ to have
keys made and programmed to the system.
121

See your dealer/retailer or a locksmith who can
service PASS-Key®III+ to get a new key blank that
is cut exactly as the ignition key that operates
the system.
To program the new additional key do the
following:
1. Verify that the new key has a
1stamped
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/retailer
for service.
3. After the engine has started, turn the key to
OFF, and remove the key.
4. Insert the new key to be programmed and
turn it to the ON position within ve seconds
of removing the original key.
5. The security light will turn off once the key
has been programmed.
6. Repeat Steps 1 through 5 if additional keys
are to be programmed.If you are driving and the security light comes on
and stays on, you may be able to restart your
engine. Your PASS-Key
®III+ system, however,
may not be working properly and must be serviced
by your dealer/retailer.
If you lose or damage your PASS-Key
®III+ key,
see your dealer/retailer or a locksmith who can
service PASS-Key
®III+ to have a new key made.

message displays on the Driver Information Center
(DIC) when there is a problem with the
theft-deterrent system. SeeDIC Warnings and
Messages on page 244for additional information.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the
vehicle.

Ignition Positions
With the key in the ignition, you can turn it to four
different positions.
A (OFF):This is the only position in which you
can remove the key. This position locks the ignition
and transmission.
Notice:Using a tool to force the key from the
ignition switch could cause damage or
break the key. Use the correct key and turn the
key only with your hand. Make sure the key
is all the way in. If none of this works,
then your vehicle needs service.B (ACCESSORY):This position allows you to use
things like the radio and the windshield wipers
while the engine is off. This position will also allow
you to turn off the engine. Use ACCESSORY if
you must have your vehicle in motion while
the engine is off, for example, if your vehicle is
being pushed or towed.
C (ON):This is the position that the switch
returns to after you start your engine and release
the key. The switch stays in ON when the
engine is running. But even when the engine is
not running, you can use ON to operate your
electrical power accessories, and to display some
instrument panel warning lights.
The battery could be drained if you leave the key
in the ACCESSORY or ON position with the
engine off. You may not be able to start your
vehicle if the battery is allowed to drain for
an extended period of time.
D (START):This position starts the engine. When
the engine starts, release the key. The ignition
switch will return to ON for normal driving.
124

DRIVE (D):This position is for normal driving. It
provides the best fuel economy for your vehicle. If
you need more power for passing, and you are:
Going less than 35 mph (56 km/h), push
your accelerator pedal about halfway down.
Going about 35 mph (56 km/h) or more, push
the accelerator all the way down.
Notice:If your vehicle seems to accelerate
slowly or not shift gears when you go faster,
and you continue to drive your vehicle that
way, you could damage the transmission. Have
your vehicle serviced right away. You can
drive in LOW (L) when you are driving less than
35 mph (56 km/h) and DRIVE (D) for higher
speeds until then.
LOW (L):This position gives you access to gear
ranges. This provides more engine braking but
lower fuel economy than DRIVE (D). You can use
it on very steep hills, or in deep snow or mud.
Electronic Range Select Mode
Electronic Range Selector (ERS) mode allows you
to choose the top-gear limit of the vehicle’s
transmission and the vehicle’s speed while driving
down hill or towing a trailer.
To use this feature, do the following:
1. Move the shift lever to LOW (L).
2. Press the plus/minus
button located on the
shift lever, to
increase or decrease
the gear range
available based
upon your current
driving conditions
and needs.
