INSTRUMENTS AND CONTROLS 99
When the vehicle is started, the
passenger airbag status indicator will
light ON and OFF, and the symbols 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, and either the
symbol for on or off, to let you know
the status of the front outboard
passenger frontal airbag and knee
airbag.
If the word ON, and the on symbol, is
lit on the passenger airbag status
indicator, it means that the front
outboard passenger frontal airbag and
knee airbag are allowed to inflate.
If the word OFF, and the off symbol, is
lit on the passenger airbag status
indicator, it means that the passenger
sensing system has turned off the
front outboard passenger frontal
airbag and knee airbag.If, after several seconds, all of the
symbols remain lit, or if no symbols
are lit, or if the airbag readiness light
is on, there may be a problem with
the lights or the passenger sensing
system. See your dealer for service
right away.
{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong with
the airbag system. To help avoid
injury to yourself or others, have
the vehicle serviced right away. See
Airbag Readiness Light
098 for more
information, including important
safety information.
Charging System Light
The charging system light comes on
briefly when the ignition is turned on,
but the engine is not running, as a
check to show the light is working.
It should go out when the engine is
started.
If the light stays on, or comes on
while driving, there may be a problem
with the electrical charging system.
Have it checked by your dealer.
Driving while this light is on could
drain the battery.
When this light comes on, or is
flashing, the Driver Information
Center (DIC) also displays a message.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio and
air conditioner. Find a safe place to
stop the vehicle.

Engine Power Messages
REDUCED ACCELERATION DRIVE
WITH CARE
This message displays when the
vehicle's propulsion power is reduced.
A reduction in propulsion power can
affect the vehicle's ability to
accelerate. If this message is on, but
there is no observed reduction in
performance, proceed to your
destination. Under certain conditions
the performance may be reduced the
next time the vehicle is driven. The
vehicle may be driven while this
message is on, but maximum
acceleration and speed may be
reduced. Anytime this message stays
on, or displays repeatedly, the vehicle
should be taken to your dealer for
service as soon as possible.
Under certain operating conditions,
propulsion will be disabled. Try
restarting after the ignition has been
off for two minutes.

LIGHTING 131
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it is
light outside when the vehicle leaves
the garage, there is a slight delay
before the automatic headlamp
system turns off the headlamps.
During that delay, the instrument
cluster may not be as bright as usual.
Make sure the instrument panel
brightness control is in the full bright
position. SeeInstrument Panel
Illumination Control 0132.
When it is bright enough outside, the
headlamps will turn off.
The automatic headlamp system turns
off when the exterior lamp control is
turned to
Oor the ignition is off. For
vehicles sold in Canada, this control
only works when the transmission is
in P (Park).
Lights On with Wipers
If the windshield wipers are activated
in daylight with the engine on, and
the exterior lamp control is in AUTO,
the headlamps, parking lamps, and
other exterior lamps come on. The
transition time for the lamps coming on varies based on wiper speed. When
the wipers are not operating, these
lamps turn off. Move the exterior
lamp control to
Oor;to disable
this feature.
Hazard Warning Flashers
|: Press this button to make the
front and rear turn signal lamps flash
on and off. Release the button for at
least one second and press again to
turn the flashers off.
The hazard warning flashers turn on
automatically if the airbags deploy.
Turn and Lane-Change
Signals

to signal a turn.
An arrow on the instrument cluster
flashes in the direction of the turn or
lane change.
Raise or lower the lever until the
arrow starts to flash to signal a lane
change. Hold it there until the lane
change is completed. If the lever is
briefly pressed and released, the turn
signal flashes three times.
The turn and lane-change signal can
be turned off manually by moving the
lever back to its original position.

To shift out of P (Park), the vehicle
must be on and the brake pedal must
be applied.
Stopping the Engine/OFF (No
Indicator Lights) : When the vehicle
is stopped, press ENGINE START/
STOP once to turn the engine off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory Power
(RAP) 0237.
If the vehicle has an automatic
transmission, and is not in P (Park),
the ignition will return to ACC/
ACCESSORY and display a message in
the Driver Information Center (DIC).
When the vehicle is shifted into
P (Park), the ignition system will
turn OFF.
If the vehicle has a manual
transmission and is stationary, the
ignition will turn off, and Retained Accessory Power (RAP) will remain
active. See
Retained Accessory Power
(RAP) 0237.
The vehicle may have an electric
steering column lock. The lock is
activated when the vehicle is switched
to OFF and the driver door is opened.
A sound may be heard as the lock
actuates or releases. The steering
column lock may not release with the
wheels turned off center. If this
happens, the vehicle may not start.
Move the steering wheel from left to
right while attempting to start the
vehicle. If this does not work, the
vehicle needs service.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake and
steering systems and disable the
airbags.
If the vehicle must be shut off in an
emergency: 1. Brake using a firm and steady pressure. Do not pump the brakes
repeatedly. This may deplete power
assist, requiring increased brake
pedal force. 2. Shift the vehicle to N (Neutral).
This can be done while the vehicle
is moving. After shifting to
N (Neutral), firmly apply the brakes
and steer the vehicle to a safe
location.
3. Come to a complete stop. Shift to P (Park) with an automatic
transmission, or Neutral with a
manual transmission. Turn the
ignition off.
4. Set the parking brake. See Electric
Parking Brake 0254.
{Warning
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the vehicle
off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
press and hold ENGINE START/STOP
for longer than two seconds, or press
twice within five seconds.

Damage to vehicle components
resulting from modifications or the
installation or use of non-GM certified
parts, including control module or
software modifications, is not covered
under the terms of the vehicle

Airbag-Equipped Vehicle 058.Vehicle Checks
Doing Your Own
Service Work
{Warning
It can be dangerous to work on
your vehicle if you do not have the
proper knowledge, service manual,
tools, or parts. Always follow
owner’s manual procedures and
consult the service manual for your
vehicle before doing any
service work.
If doing some of your own service
work, use the proper service manual.
It tells you much more about how to
service the vehicle than this manual
can. To order the proper service
manual, see Publication Ordering
Information 0437.
This vehicle has an airbag system.
Before attempting to do your own
service work, see Servicing the
Airbag-Equipped Vehicle 058. If equipped with remote vehicle start,
open the hood before performing any
service work to prevent remote
starting the vehicle accidentally. See
Remote Vehicle Start
013.
Keep a record with all parts receipts
and list the mileage and the date of
any service work performed. See
Maintenance Records 0421.
Caution
Even small amounts of
contamination can cause damage to

exhibit premature durability/corrosion
problems, and may not perform
properly in subsequent collisions.
Aftermarket parts are not covered by
the GM New Vehicle Limited
Warranty, and any vehicle failure
related to such parts is not covered by
that warranty.
Repair Facility
GM also recommends that you choose
a collision repair facility that meets
your needs before you ever need
collision repairs. Your dealer may have
a collision repair center with
GM-trained technicians and
state-of-the-art equipment, or be able
to recommend a collision repair center
that has GM-trained technicians and
comparable equipment.
Insuring the Vehicle
Protect your investment in the GM
vehicle with comprehensive and
collision insurance coverage. There are
significant differences in the quality of
coverage afforded by various
insurance policy terms. Many
insurance policies provide reduced
protection to the GM vehicle bylimiting compensation for damage
repairs by using aftermarket collision
parts. Some insurance companies will
not specify aftermarket collision parts.
When purchasing insurance, we
recommend that you ensure that the
vehicle will be repaired with GM
original equipment collision parts.
If such insurance coverage is not
available from your current insurance
carrier, consider switching to another
insurance carrier.
If the vehicle is leased, the leasing
company may require you to have
insurance that ensures repairs with
Genuine GM Original Equipment
Manufacturer (OEM) parts or Genuine
Manufacturer replacement parts. Read
the lease carefully, as you may be
charged at the end of the lease for
poor quality repairs.If a Crash Occurs
If there has been an injury, call
emergency services for help. Do not
leave the scene of a crash until all
matters have been taken care of. Move
the vehicle only if its position puts
you in danger, or you are instructed to
move it by a police officer.Give only the necessary information
to police and other parties involved in
the crash.
For emergency towing see
Roadside
Service 0432.
Gather the following information:
.Driver name, address, and telephone
number
.Driver license number
.Owner name, address, and
telephone number
.Vehicle license plate number
.Vehicle make, model, and
model year
.Vehicle Identification Number (VIN)
.Insurance company and policy
number
.General description of the damage
to the other vehicle
Choose a reputable repair facility that
uses quality replacement parts. See
“Collision Parts ”earlier in this section.
