When Should an Airbag Inate?
The driver’s and right front passenger’s frontal
airbags are designed to inate in moderate to
severe frontal or near-frontal crashes. But they are
designed to inate only if the impact exceeds a
predetermined deployment threshold. Deployment
thresholds take into account a variety of desired
deployment and non-deployment events and are
used to predict how severe a crash is likely to be in
time for the airbags to inate and help restrain the
occupants. Whether your frontal airbags will or
should deploy is not based on how fast your vehicle
is traveling. It depends largely on what you hit, the
direction of the impact, and how quickly your
vehicle slows down.
Your vehicle has a dual-stage driver airbag, which
adjusts the restraint according to crash severity
using electronic frontal sensor(s), which help
the sensing system distinguish between a
moderate frontal impact and a more severe frontal
impact. The dual-stage driver airbag inates to
a level less than full deployment for moderate
frontal impacts and to a full deployment for more
severe frontal impacts.Your vehicle has a dual-depth passenger airbag
that adjusts the restraint according to crash
severity and seat location using electronic frontal
sensor(s) and other special sensors which
enable the sensing system to monitor the status of
the position of the front passenger seat. The
passenger airbag inates to a reduced depth when
the passenger seat is in a forward position. For
more rearward front seating positions, the
passenger airbag may inate to an increased
depth (a full deployment), based on the crash
severity measured early in the event. Always wear
your safety belt, even with frontal airbags.
If the front of your vehicle goes straight into a wall
that does not move or deform, the threshold
level for the reduced deployment is about
12 to 16 mph (19 to 26 km/h), and the threshold
level for a full deployment is about 18 to 24 mph
(29 to 38.5 km/h). The threshold level can
vary, however, with specic vehicle design, so that
it can be somewhat above or below this range.

The passenger sensing system will turn off the
right front passenger’s frontal airbag under certain
conditions. The driver’s airbags are not part of
the passenger sensing system.
The passenger sensing system works with
sensors that are part of the right front passenger’s
seat. The sensors are designed to detect the
presence of a properly-seated occupant and
determine if the passenger’s frontal airbag should
be enabled (may inate) or not.
Accident statistics show that children are safer if
they are restrained in the rear rather than the front
seat. We recommend that child restraints be
secured in a rear seat, including an infant riding in
a rear-facing infant seat, a child riding in a
forward-facing child seat, and an older child riding
in a booster seat.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun
visor says, “Never put a rear-facing child seat
in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.
{CAUTION:
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag.
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint, no
system is fail-safe, and no one can

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, height,
front end or side sheet metal, they may keep
the airbag system from working properly.
Also, the airbag system may not work properly
if you relocate any of the airbag sensors. If
you have any questions about this, you should
contact Customer Assistance before you
modify your vehicle. The phone numbers and
addresses for Customer Assistance are in
Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 488.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the
front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel,
instrument panel, ceiling headliner, ceiling and
pillar garnish trim, roof-mounted airbag
modules, or airbag wiring can affect the
operation of the airbag system. If you have
questions, call Customer Assistance. The
phone numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual.

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 before the 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 hold
open temporarily, then slowly close. See your
dealer 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 fully closed or open position. After
removing the obstruction, the liftgate may be
power opened or closed normally.If the liftgate encounters multiple obstacles on the
same power cycle, the power function will
deactivate, and the liftgate will switch to manual
operation. The REAR ACCESS 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
fully open position or close the liftgate to the
fully closed and latched position. The liftgate will
now resume normal power operation.
Your vehicle has an obstacle detection sensor
located on the rear edge of the rear quarter panel
windows. If an object is caught between the
liftgate and the window 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.

When the exterior lamp control is in AUTO and it is
dark enough outside, the DRL will turn off and the
low-beam headlamps will turn on. When it is bright
enough outside, the low-beam headlamps will go
off, and the DRL will turn back on. If you start the
vehicle in a dark garage, the automatic headlamp
system will come on immediately. Once you leave
the garage, it will take about one minute for the
automatic headlamp system to change to DRL if it
is light outside. During that delay, the instrument
panel cluster may not be as bright as usual. Make
sure the instrument panel brightness lever is in the
full bright position. SeeInstrument Panel Brightness
on page 181.
To drive the vehicle with the DRL off, turn the
exterior lamp control off. Then turn on the
fog lamps or parking lamps, and the DRL will turn
off. This will work regardless of gear position
and whether or not the parking brake is set.
As with any vehicle, you should turn on the regular
headlamp system when you need it.Light Sensor
The light sensor for the DRL and AUTO headlamp
feature is located on top of the instrument panel.
If you cover the sensor, it will prevent it from
sensing light, and the exterior lamps may come on
whenever the ignition is on.

Entry Lighting
The entry lighting system turns on the reading and
dome lamps and the backlighting to the exterior
lamp control when a door is opened or if the
Remote Keyless Entry (RKE) transmitter unlock
button is pressed. If activated by the (RKE),
the lighting will remain active for about 25 seconds.
The entry lighting system uses the light sensor
on the instrument panel; so it must be dark outside
in order for the lamps to turn on. The lamps turn
off about 25 seconds after the last door is
closed. They will dim to off if the ignition key is
turned to ON, or immediately turn off if the power
locks are used.
Parade Dimming
This feature prohibits dimming of the instrument
panel displays and backlighting during daylight
hours when the key is in the ignition and the
headlamps are on. This feature operates with the
light sensor and is fully automatic. When the light
sensor reads darkness outside and the parking
lamps are active, the instrument panel displays can
be adjusted by sliding the instrument panel
brightness lever toward the symbol to brighten or
away from the symbol to dim the lighting.
Reading Lamps
The reading lamps are located on the overhead
console. These lamps come on automatically when
any door is opened.
For manual operation, press the button next to
each lamp to turn it on or off.
If the reading lamps are left on, they automatically
shut off 10 minutes after the ignition has been
turned off.

The URPA display is
located inside the
vehicle, above the
liftgate glass. It
has three color-coded
lights that can be
seen through the
rearview mirror or by
turning around.
How the System Works
URPA comes on automatically when the shift lever
is moved into REVERSE (R) and the vehicle
speed is less than 3 mph (5 km/h). When
the system turns on, the three lights on the display
will illuminate for one and a half seconds to let
you know that the system is working. If your
vehicle is moving in REVERSE (R) at a speed
greater than 3 mph (5 km/h), the red light will ash
to remind you that the system does not work at
a speed greater than 3 mph (5 km/h).If an object is detected at a REVERSE (R) speed
of less than 3 mph (5 km/h), one of the following
will occur:
Description English Metric
Amber light 5 ft 1.5 m
Amber/amber lights 40 in 1.0 m
Amber/amber/red lights &
continuous chime20 in 0.5 m
Amber/amber/red lights
ashing & continuous
chime1 ft 0.3 m
A chime will sound the rst time an object is
detected between 20 inches (0.5 m) and 5 feet
(1.5 m) away.
URPA cannot detect objects that are above liftgate
level. In order for the rear sensors to recognize
an object, it must be within detection range behind
the vehicle.
185

When the System Does Not Seem to Work
Properly
The light may ash red when the vehicle is in
REVERSE (R), if the ultrasonic sensors are not
kept clean. So be sure to keep your rear bumper
free of mud, dirt, snow, ice and slush. Other
conditions that may affect system performance
include things like the vibrations from a jackhammer
or the compression of air brakes on a very large
truck. If after cleaning the rear bumper and then
driving forward at least 15 mph (25 km/h), the
display continues to ash red, see your dealer.
If a trailer was attached to your vehicle, or a
bicycle or an object was on the back of, or hanging
out of your liftgate during your last drive cycle,
the light may also ash red. The light will continue
to ash whenever in REVERSE (R) until your
vehicle is driven forward at least 15 mph (25 km/h)
without any obstructions behind the vehicle.
For cleaning instructions, seeWashing Your
Vehicle on page 447.
Accessory Power Outlet(s)
The accessory power outlets can be used to plug
in electrical equipment such as a cellular
telephone, CB radio, etc.
The vehicle has one outlet in front of the center
console on the instrument panel and one in
the rear compartment. Your vehicle may have
one or two outlets in the rear of the center console.
There is a small cap that must be removed to
access the accessory power outlet. When
not using the outlet be sure to cover it with the
protective cap.
Notice:Leaving electrical equipment plugged
in for an extended period of time while the
vehicle is off will drain the battery. Power is
always supplied to the outlets. Always unplug
electrical equipment when not in use and
do not plug in equipment that exceeds
the maximum 20 ampere rating.

0(Defrost):Turn the control to this position so
that most of the air is directed to the windshield
with some air going to the side window outlets.
More information on defrosting can be found later
in this section.
O(On/Off):Press this button to turn the climate
control system on or off. While off, adjusting
any button or control, except recirculation and rear
window defog turns the system back on. The air
inlets default to outside air when the climate
control system is turned off.
PASS (Passenger’s Climate Control):Press this
button to turn the passenger’s climate control
system on or off. Then press the up or down
buttons to choose the desired setting. Pressing
the button again automatically sets the passengers
temperature to the drivers setting. Turning the
passenger’s temperature display off does not turn
off the climate control system for the passenger.
Recirculation Operation
There are three options for bringing air into the
climate control system. They are controlled
by pressing the center button on the climate
control panel. The climate control display indicates
one of the following three modes:
9AUTO (Auto Air Inlet):This mode lets the
automatic climate control system choose the
best air inlet position for cooling or warming the
vehicle. To have full automatic climate control,
the fan and mode controls must be set to
the AUTO position. Generally, recirculation will
only automatically be selected on hot days.
Your vehicle may have an optional Air Quality
Sensor. To activate the air quality sensor, the
auto air inlet setting must be used. For more
information, see Air Quality Sensor found later
in this section.
191

?(Recirculation):This mode recirculates air
inside the vehicle and keeps outside air from
coming into the vehicle. It can be used to help cool
the vehicle more quickly or to prevent odors
from entering the vehicle.
Recirculation is not available in the defrost mode.
It is also cancelled when oor or defog mode
is selected. In some conditions using recirculation
for long periods of time can cause the air inside
the vehicle to become too dry or stuffy. To prevent
this from happening, after the air in the vehicle
has cooled, select auto air inlet or outside air.
:(Outside Air):This mode pulls fresh air from
outside the vehicle. Outside air is always
selected in defrost mode to prevent fogging.
Air Conditioning
#
(Air Conditioning):Press this button to turn
the air conditioning on or off, and override the
automatic system. When selecting the AUTO fan
or AUTO mode, the air conditioning compressor
comes on automatically, as necessary.The air conditioning system removes moisture
from the air, so you might notice water dripping
underneath the vehicle while idling or after turning
off the engine. This is normal.
Sensors
There is a solar sensor located on top of the
instrument panel, near the windshield.
