{WARNING
Exhaust gases can enter the
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
exhaust contains Carbon
Monoxide (CO) which cannot be
seen or smelled. It can cause
unconsciousness and even death.
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.(Continued)
WARNING (Continued)
.Adjust the Climate Control
system to a setting that
brings in only outside air and
set the fan speed to the
highest setting. See Climate
Control System in the Index.
.If the vehicle is equipped with
a power liftgate, disable the
power liftgate function.
For more information about

Obstacle Detection Features
A warning chime will sound and the
liftgate will automatically reverse
direction to the full closed or open
position if the liftgate encounters an
obstacle during a power open or
close cycle. After removing the
obstruction, the power liftgate
operation can be used again.
If the liftgate comes across more
obstacles on the same power cycle,
the power function deactivates, and
you must manually open or close
the liftgate. A message displays,
LIFTGATE OPEN, to indicate that
the liftgate is open. SeeDriver
Information Center (DIC) (With DIC
Buttons)

on page 5‑28for
more information. 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
resumes 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. Do not
force the liftgate open or closed
during a power cycle.

Vehicle Security
Vehicle theft is big business,

When the door is closed, the
security light stops flashing and
stays on solid for approximately 30 seconds. The content theft
deterrent alarm is not armed

been set off.
To avoid setting off the alarm by

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 comes on if there
is a problem with arming or
disarming the theft-deterrent
system.
When the PASS-Key
®III+ system
senses an incorrect key, the vehicle
does not start. 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, there may be a problem
with your 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 and check
the fuses. See
Fuses and Circuit
Breakers
on page 10‑31for
additional information. 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/retailer
who can service the PASS-Key
®III+
to have a new key made. In an
emergency, contact Roadside
Assistance. See Roadside
Assistance Program on page 13‑5.
