What Makes an Airbag Inate?
In a deployment event, the sensing system sends
an electrical signal triggering a release of gas
from the inator. Gas from the inator lls
the airbag causing the bag to break out of the
cover and deploy. The inator, the airbag,
and related hardware are all part of the airbag
module.
Frontal airbag modules are located inside the
steering wheel and instrument panel. For vehicles
with seat-mounted side impact airbags, there
are airbag modules in the side of the front
seatbacks closest to the door. For vehicles with
roof-rail airbags, there are airbag modules in
the ceiling of the vehicle, near the side windows
that have occupant seating positions.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal
collisions, even belted occupants can contact the
steering wheel or the instrument panel. In
moderate to severe side collisions, even belted
occupants can contact the inside of the vehicle.Airbags supplement the protection provided by
safety belts.
Frontal airbags distribute the force of the impact
more evenly over the occupant’s upper body,
stopping the occupant more gradually.
Seat-mounted side impact and roof-rail airbags
distribute the force of the impact more evenly over
the occupant’s upper body.
Rollover capable roof-rail airbags are designed to
help contain the head and chest of occupants
in the outboard seating positions in the rst,
second, and third rows. The rollover capable
roof-rail airbags are designed to help reduce the
risk of full or partial ejection in rollover events,
although no system can prevent all such ejections.
But airbags would not help in many types of
collisions, primarily because the occupant’s motion
is not toward those airbags. SeeWhen Should
an Airbag Inflate? on page 81for more information.
Airbags should never be regarded as anything
more than a supplement to safety belts.

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 and has
adequate voltage, and the liftgate still will not
function, your vehicle should be taken to a
dealership for service.
Power Liftgate
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.

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.

Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to time out or quit after several seconds
of transmission. This may not be long enough
for Universal Home Remote to pick up the signal
during programming. Similarly, some U.S. gate
operators are manufactured to time out in
the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator or garage door
opener by using the “Programming Universal
Home Remote” procedures, regardless of where
you live, replace Step 3 under “Programming
Universal Home Remote” with the following:
Continue to press and hold the Universal Home
Remote button while you press and release every
two seconds (cycle) the hand-held transmitter
button until the frequency signal has been
successfully accepted by the Universal Home
Remote. The Universal Home Remote indicator
light will ash slowly at rst and then rapidly.
Proceed with Step 4 under “Programming
Universal Home Remote” to complete.
Using Universal Home Remote
Press and hold the appropriate Universal Home
Remote button for at least half of a second.
The indicator light will come on while the signal is
being transmitted.
Erasing Universal Home Remote
Buttons
To erase programming from the three Universal
Home Remote buttons do the following:
1. Press and hold down the two outside buttons
until the indicator light begins to ash, after
20 seconds. Do not hold the two outside
buttons for longer than 30 seconds.
2. Release both buttons.
The Universal Home Remote is now in the training
(learning) mode and can be programmed at any
time beginning with Step 2 under “Programming
Universal Home Remote” shown earlier in
this section.
Individual buttons cannot be erased, but they can
be reprogrammed. See “Reprogramming a
Single Universal Home Remote Button” following
this section.

2. Write down the eight to 12 switch settings
from left to right as follows:
When a switch is in the up position,
write “Left.”
When a switch is in the down position, write
“Right.”
If a switch is set between the up and down
position, write “Middle.”
The switch settings that you wrote down in
Step 2 will now become the button strokes
you enter into the Universal Home Remote in
Step 4. Be sure to enter the switch settings
that you wrote down in Step 2, in order from
left to right, into the Universal Home Remote,
when completing Step 4.
3. From inside your vehicle, rst rmly press
all three buttons at the same time for about
three seconds. Release the buttons to put
the Universal Home Remote into
programming mode.4. The indicator lights will blink slowly. Enter each
switch setting from Step 2 into your vehicle’s
Universal Home Remote. You will have two
and one-half minutes to complete Step 4. Now
press one button on the Universal Home
Remote for each switch setting as follows:
If you wrote “Left,” press the left button in the
vehicle.
If you wrote “Right,” press the right button in
the vehicle.
If you wrote “Middle,” press the middle
button in the vehicle.

Delayed Exit Lighting
This feature illuminates the interior for a period of
time after the key is removed from the ignition.
The ignition must be off for delayed exit lighting to
work. When the key is removed, interior illumination
will activate and remain on until one of the following
occurs:
The ignition is in ON.
The power door locks are activated.
An illumination period of 20 seconds
has elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled
and the interior lamps will remain on because a
door is open.
Parade Dimming
The instrument panel has an added feature called
parade mode. It automatically prohibits the
dimming of the instrument panel displays during
the daylight while the headlamps are on so
that you will still be able to see the displays.
Reading Lamps
The vehicle has reading lamps that also act as the
dome lamp. Press the button to turn them on and off.
Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature and state
of charge. It then adjusts the voltage for best
performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or voltage
display on the Driver Information Center (DIC),
you may see the voltage move up or down. This
is normal. If there is a problem, an alert will be
displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to
produce all the power that is needed for very
high electrical loads.

Temperature Control:Turn the center knob
clockwise or counterclockwise to increase
or decrease the temperature of the air owing
from the system.
Airow Mode Control:Turn the right knob
clockwise or counterclockwise to direct the airow
inside of the vehicle.
To change the current mode, select one of the
following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs about half of
the air to the instrument panel outlets and
half to the oor outlets. A little air is directed
towards the windshield and side window outlets.
Cooler air is directed to the upper outlets and
warmer air to the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets, with some of the air directed
to the windshield, side window outlets, and
second row oor outlets. In this mode, the system
automatically selects outside air. Recirculation
cannot be selected when in Floor Mode.The right knob can also be used to select defog
or defrost mode. For more information, see
“Defogging and Defrosting” later in this section.
By positioning the right knob between two modes,
a combination of those two modes is selected.
@(Recirculation):Press this button to turn the
recirculation mode on or off. The indicator light
on the button turns on when this mode is selected.
This mode keeps outside air from entering the
vehicle. It can be used to reduce the outside air
and odors entering the vehicle. Recirculation
may also help cool the air inside the vehicle more
quickly once the temperature inside the vehicle
is less than the outside temperature.
The recirculation mode can be turned off in vent
and bi-level modes by pressing the button
again. Recirculation mode automatically turns off
when the engine is turned off and must be
re-selected when the engine is turned on again.
The recirculation mode cannot be used with
oor, defrost, or defogging modes. If you try to
select recirculation in one of those modes,
the indicator ashes three times and turns off.
