Airbag System
Your vehicle has a frontal airbag for the driver
and a frontal airbag for the right front passenger.
Your vehicle also has roof-mounted rollover
airbags designed for either side impact or rollover
deployment. Roof-mounted rollover airbags are
available for the driver and the passenger seated
directly behind the driver and for the right front
passenger and the passenger seated directly
behind that passenger.
For roof-mounted rollover airbags, the word
AIRBAG will appear on the airbag covering on the
ceiling above the sidewall trim near the driver’s
and right front passenger’s window and the
second row outside seating positions.
Also, if your vehicle has a third row passenger
seat, your vehicle will have third row roof-mounted
rollover airbags.
Frontal airbags are designed to help reduce
the risk of injury from the force of an inating
frontal airbag. But these airbags must inate very
quickly to do their job and comply with federal
regulations.Here are the most important things to know about
the airbag system:
{CAUTION:
You can be severely injured or killed in a
crash if you are not wearing your safety
belt — even if you have airbags. Wearing
your safety belt during a crash helps
reduce your chance of hitting things
inside the vehicle or being ejected from it.
Airbags are “supplemental restraints” to
the safety belts. All airbags are designed
to work with safety belts but do not
replace them.
Frontal airbags for the driver and right
front passenger are designed to deploy in
moderate to severe frontal and near frontal
crashes.
CAUTION: (Continued)
90

CAUTION: (Continued)
They are not designed to inate in
rollover, rear crashes, or in many side
crashes. And, for some unrestrained
occupants, frontal airbags may provide
less protection in frontal crashes than
more forceful airbags have provided in
the past.
Roof-mounted rollover airbags are
designed to inate in moderate to severe
crashes where something hits the side of
your vehicle, during a vehicle rollover,
or in a severe frontal impact. They are not
designed to inate in rear crashes. If your
vehicle has roof-mounted airbags, they
are designed to provide both side impact
protection and rollover protection.
Everyone in your vehicle should wear a
safety belt properly — whether or not there
is an airbag for that person.
{CAUTION:
Both frontal and roof-mounted rollover
airbags inate with great force, faster than
the blink of an eye. If you are too close to
an inating airbag, as you would be if you
were leaning forward, it could seriously
injure you. Safety belts help keep you in
position for airbag ination before and
during a crash. Always wear your safety
belt even with frontal airbags. The driver
should sit as far back as possible while
still maintaining control of the vehicle.
Occupants should not lean on or sleep
against the door in the rst or second row
seats, or the rear windows in the third row
seat, if your vehicle has roof-mounted
rollover airbags.

When driving with the liftgate open, the power
liftgate should be switched to manual liftgate
operation — the overhead console switch set to
the “Disable” position.
Both the liftglass and liftgate have an electric
latch. If the battery is disconnected or has
low voltage, the liftglass and liftgate will not open.
The liftglass and liftgate will resume operation
when the battery is reconnected and charged.
If the battery is properly connected and has
adequate voltage, and the liftgate or liftglass still
will not function, your vehicle should be taken to a
dealership for service.
{CAUTION:
It can be dangerous to drive with the
liftglass or 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 liftglass or
liftgate open, or if electrical wiring or
other cable connections must pass
through the seal between the body and
the liftglass or 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.
SeeDual Automatic Climate Control
System on page 214.
If you have air outlets on or under
the instrument panel, open them all
the way.
If your vehicle is equipped with a
power liftgate, disable the power
liftgate function.
SeeEngine Exhaust on page 156.
Do not drive with the liftgate open if at all possible.

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 about 35 mph (55 km/h), push
your accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push
the accelerator all the way down.
Drive (D) can be used when towing a trailer,
carrying a heavy load, driving on steep hills,
or for off-road driving. You may want to shift the
transmission to a lower gear selection if the
transmission shifts too often.
Downshifting the transmission in slippery road
conditions could result in skidding, see Skidding
underLoss of Control on page 357.
When temperatures are very cold, the
Hydra-Matic
®Automatic Transmission’s gear
shifting may be delayed providing more stable
shifts until the engine warms up. Shifts may
be more noticeable with a cold transmission.
This difference in shifting is normal.MANUAL MODE (M):This position lets drivers
select the range of gears appropriate for current
driving conditions. If your vehicle has this feature,
see “Driver Shift Control” later in this section.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only
the accelerator pedal may damage the
transmission. If you are stuck, do not spin
the tires. When stopping on a hill, use
the brakes to hold the vehicle in place.
Your vehicle has a shift stabilization feature that
adjusts the transmission shifting to the current
driving conditions in order to reduce rapid upshifts
and downshifts. This shift stabilization feature is
designed to determine, before making an upshift,
if the engine will be able to maintain vehicle
speed by analyzing things such as throttle position,
vehicle load, and hill grade. If the shift stabilization
feature determines that a current vehicle speed
cannot be maintained, the transmission does
not upshift and instead holds the current gear.
In some cases, this may appear to be a delayed
shift, however the transmission is operating
normally.

Automatic Dimming Mirror Operation
The automatic dimming mirror function is turned on
automatically each time the ignition is started.
To operate the automatic dimming mirror, do the
following:
1. Make sure the green indicator light, located to
the left of the on/off button, is lit. If it’s not, press
and hold the on/off button for approximately
six seconds until the green light comes on,
indicating that the mirror is in automatic
dimming mode.
2. Turn off the automatic dimming mirror function
by pressing and holding the on/off button for
approximately six seconds, until the green
indicator light turns off.
Compass Variance
The mirror is set in zone eight upon leaving the
factory. It will be necessary to adjust the compass
to compensate for compass variance if you live
outside of zone eight. Under certain circumstances,
as during a long distance cross-country trip, it will
be necessary to adjust for compass variance.Compass variance is the difference between earth’s
magnetic north and true geographic north. If not
adjusted to account for compass variance, your
compass could give false readings.
To adjust for compass variance do the following:
1. Find your current location and variance
zone number on the following zone map.
159

2. Press and hold the on/off button untilaZand
a zone number appear in the display. The
compass is now in zone mode.
3. Keep pressing the on/off button until the
desired zone number appears in the display.
Release the button. After approximately
four seconds of inactivity, the new zone
number will be locked in and the compass/
temperature display will return.
4. Calibrate the compass as described below.
Compass Calibration
The compass may need calibration if one of the
following occurs:
After approximately ve seconds, the display
does not show a compass heading (N for
North, for example), there may be a strong
magnetic eld interfering with the compass.
Such interference may be caused by a
magnetic antenna mount, magnetic note pad
holder or a similar magnetic item.
The compass does not display the correct
heading and the compass zone variance
is set correctly.In order to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed,
push the on/off button for approximately
12 seconds or until CAL is displayed.
The compass can be calibrated by driving the
vehicle in circles at 5 mph (8 km/h) or less until the
display reads a direction.
Cleaning the Mirror
When cleaning the mirror, use a paper towel or
similar material dampened with glass cleaner. Do
not spray glass cleaner directly on the mirror
as that may cause the liquid cleaner to enter the
mirror housing.
