Passenger Sensing
System
The vehicle has a passenger
sensing system for the right front
passenger position. The passenger
airbag status indicator will be visible
in the rearview mirror when you start
the vehicle.
The words ON and OFF, or the
symbol for on and off, will be visible
during the system check. When the
system check is complete, either the
word ON or the word OFF, or the
symbol for on or the symbol for off,
will be visible. SeePassenger Airbag
Status Indicator on page 4-15.
The passenger sensing system will
turn off the right front passenger’s
frontal airbag and seat-mounted
side impact 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 right
front passenger’s frontal airbag and
seat-mounted side impact airbag
should be enabled (may in ate)
or not.
Accident statistics show that
children are safer if they are
restrained in the rear rather than
the front seat.
We recommend that children be
secured in a rear seat, including: an
infant or a child riding in a rear-facing
child restraint; a child riding in a
forward-facing child seat; an older
child riding in a booster seat; and
children, who are large enough,
using safety belts. United States

Mirrors
Manual Rearview Mirror
Hold the mirror in the center to move
it for a clearer view of behind your
vehicle.
Headlamp Glare
To reduce headlamp glare from
vehicles following from behind, pull
the lever toward you. Push the
lever forward after the vehicle glare
is gone, to return the mirror back
to the original position.
Vehicles with OnStar
®have three
OnStar®control buttons located at
the bottom of the mirror. See your
dealer/retailer for more information
on the system and how to subscribe
to OnStar
®. SeeOnStar®System on
page 4-38.
Cleaning the Mirror
Do not spray glass cleaner directly
on the mirror. Use a soft towel
dampened with glass cleaner.
Outside Mirror(s)
To maximize the viewing area,
adjust each mirror to see the side of
your vehicle and the area beside
and behind your vehicle.
Manually fold the mirrors at against
the side of the vehicle by pushing
them toward the vehicle’s doors.

Windshield Wipers
Clear ice and snow from the wiper
blades before using them. If the
wiper blades are frozen to the
windshield, gently loosen or thaw
them. If the blades do become
damaged, install new blades or
blade inserts. SeeWindshield Wiper
Blade Replacement on page 9-21.
Heavy snow or ice can overload the
wiper motor. A circuit breaker will
stop the motor until it cools down.
Clear away snow or ice to prevent
an overload.The lever on the right side of the
steering column operates the
windshield wipers. Push up or pull
down on the lever to place it in
one of the following positions.
[(High):For rapid wiping cycles.
— (Low):For slow, steady wiping
cycles.
-- (Intermittent/RainSense™):
See RainSense™ wipers below.
9(Off):Turns off the wipers.For a single wipe pull the lever
down from the off position. The lever
will return to its original position.
For more cycles, hold the lever
down before releasing it.
RainSense™ Wipers
There is a moisture sensor mounted
on the windshield next to the inside
rearview mirror. When active, the
sensor is able to detect moisture on
the windshield and automatically
control the frequency of the wipes
according to the weather conditions.
To turn on the RainSense feature,
the wipers must be set to the
intermittent delay setting on
the windshield wiper lever.
To turn off RainSense, move the
lever downwards.
Notice:Going through an
automatic car wash with the
wipers on can damage them.
Turn the wipers off when going
through an automatic car wash.

If the airbag readiness light stays on
after you start the vehicle or comes
on when your are driving, your airbag
system may not work properly. Have
your vehicle serviced right away.
{CAUTION
If the airbag readiness light
stays on after the vehicle is
started, it means the airbag
system may not be working
properly. The airbags in the
vehicle may not in ate in a
crash, or they could even
in ate without a crash.
To help avoid injury, have the
vehicle serviced right away.
Passenger Airbag Status
Indicator
The vehicle has a passenger
sensing system. The rearview
mirror has a passenger airbag
status indicator.
When you start the vehicle, the
passenger airbag status indicator
will light ON and OFF, or the symbol
for on and off, for several seconds
as a system check. Then, after
several more seconds, the status
indicator will light either ON or OFF,
or either the on or off symbol to let
you know the status of the right
front passenger’s frontal and
seat-mounted side impact airbags. United States

If your vehicle starts to slide, ease
your foot off the accelerator pedal
and quickly steer the way you want
the vehicle to go. If you start steering
quickly enough, your vehicle may
straighten out. Always be ready for a
second skid if it occurs.
Of course, traction is reduced when
water, snow, ice, gravel, or other
material is on the road. For safety,
you want to slow down and
adjust your driving to these
conditions. It is important to slow
down on slippery surfaces because
stopping distance is longer and
vehicle control more limited.
While driving on a surface with
reduced traction, try your best to
avoid sudden steering, acceleration,
or braking, including reducing
vehicle speed by shifting to a lower
gear. Any sudden changes could
cause the tires to slide. You
might not realize the surface isslippery until your vehicle is
skidding. Learn to recognize warning
clues — such as enough water,
ice, or packed snow on the road to
make a mirrored surface — and
slow down when you have any
doubt.
Remember: Any Antilock Brake
System (ABS) helps avoid only the
braking skid.
Driving at Night
Night driving is more dangerous
than day driving because some
drivers are likely to be impaired — by
alcohol or drugs, with night vision
problems, or by fatigue.
Night driving tips include:
Drive defensively.
Do not drink and drive.
Reduce headlamp glare by
adjusting the inside rearview
mirror.
Slow down and keep more space
between you and other vehicles
because headlamps can only
light up so much road ahead.
Watch for animals.
When tired, pull off the road.
Do not wear sunglasses.
Avoid staring directly into
approaching headlamps.
Keep the windshield and all glass
on your vehicle clean — inside
and out.
Keep your eyes moving,
especially during turns or curves.
No one can see as well at night as
in the daytime. But, as we get
older, these differences increase.
A 50-year-old driver might need
at least twice as much light to see
the same thing at night as a
20-year-old.

Before Leaving on a
Long Trip
To prepare your vehicle for a long
trip, consider having it serviced by
your dealer/retailer before departing.
Things to check on your own
include:
Windshield Washer Fluid:
Reservoir full? Windows
clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All
levels checked?
Lamps:Do they all work and are
lenses clean?
Tires:Are treads good? Are tires
in ated to recommended
pressure?
Weather and Maps:Safe to
travel? Have up-to-date maps?
Highway Hypnosis
Always be alert and pay attention
to your surroundings while driving.
If you become tired or sleepy, nd
a safe place to park your vehicle
and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.
Keep your eyes moving — scan
the road ahead and to the sides.
Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on at or rolling terrain. Tips for
driving in these conditions include:
Keep the vehicle serviced
and in good shape.
Check all uid levels and brakes,
tires, cooling system, and
transmission.
Going down steep or long hills,
shift to a lower gear.
{CAUTION
If you do not shift down, the
brakes could get so hot that
they would not work well. You
would then have poor braking
or even none going down a hill.
You could crash. Shift down to
let the engine assist the brakes
on a steep downhill slope.
