Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change the vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts
of the front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel, instrument
panel, roof-rail airbag modules, ceiling headliner
or pillar garnish trim, front sensors, side impact
sensors, rollover sensor module, or airbag wiring
can affect the operation of the airbag system.
In addition, the vehicle has a passenger sensing
system for the right front passenger position, which
includes sensors that are part of the passenger seat.The passenger sensing system may not operate
properly if the original seat trim is replaced with
non-GM covers, upholstery or trim, or with GM
covers, upholstery or trim designed for a different
vehicle. Any object, such as an aftermarket seat
heater or a comfort enhancing pad or device,
installed under or on top of the seat fabric, could
also interfere with the operation of the passenger
sensing system. This could either prevent proper
deployment of the passenger airbag(s) or prevent
the passenger sensing system from properly turning
off the passenger airbag(s). SeePassenger Sensing
System (Without Turbo/With Turbo and RPO AS5)
on page 1-66orPassenger Sensing System (With
Turbo and RPO AR9 or AE4) on page 1-72.
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. See
Customer Satisfaction Procedure on page 7-2.
If the vehicle has rollover roof-rail airbags,
seeDifferent Size Tires and Wheels on page 5-71
for additional important information.

Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high
beam, push the turn signal lever away from you.
This indicator light appears
on the instrument panel
cluster when the high
beams are on.
To change the headlamps from high beam to low beam,
pull the turn signal lever toward you.
Flash-to-Pass
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass.
To use it, pull the turn signal/multifunction lever toward
you until the high-beam headlamps come on, then
release the lever to turn them off.
Windshield Wipers
The windshield wiper lever is located on the right side of
the steering wheel.
Move the lever to one of the following positions:
1(High Speed):For steady wiping at high speed.
6(Low Speed):For steady wiping at low speed.
&(Delay):Use to set a delay between wipes.
3-8

{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do not
use the cruise control on winding roads or in
heavy traffic.
Cruise control can be dangerous on slippery roads.
On such roads, fast changes in tire traction can
cause excessive wheel slip, and you could lose
control. Do not use cruise control on slippery roads.
Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you are not
using cruise, you might hit a button and go into
cruise when you do not want to. You could be
startled and even lose control. Keep the cruise
control switch off until you want to use cruise
control.The cruise control buttons
are located on the left side
of the steering wheel.
J(On/Off):Press to turn the cruise control system on
and off. The indicator light on the button comes on
when the cruise control is on and goes off when
the cruise control is turned off.
RES+ (Resume):Press to resume a set speed and to
accelerate the speed.

Automatic Headlamp System
When it is dark enough outside, the automatic system
turns on the headlamps at the normal brightness along
with other lamps such as the taillamps, sidemarker,
parking lamps, instrument panel lights, and interior switch
backlighting.
Do not cover the light sensor, located on top of the
instrument panel. If the sensor is covered the headlamps
may remain on when they are not needed.
If the vehicle is driven through a parking garage, overcast
weather or a tunnel, the automatic headlamp system may
turn on.
There is a delay in the transition between the daytime
and nighttime operation of the automatic lamp control
system so that driving under bridges or bright overhead
street lights does not affect the system. The automatic
lamp control system will only be affected when the light
sensor sees a change in lighting lasting longer than this
delay.
If the vehicle is started in a dark garage, the automatic
lamp system turns on immediately. Once the vehicle
exits the garage, it will take about 20 seconds for the
automatic lamp 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 control is in the full bright position.
SeeInstrument Panel Brightness on page 3-17.To idle the vehicle with the system off, turn the ignition
on and turn the exterior light switch to the off/on position.
For vehicles rst sold in Canada, the transmission must
stay in P (Park) for this function or the parking brake must
be set for vehicles with manual transmissions.
Turn on the regular headlamps when they are needed.
Fog Lamps
For vehicles with fog lamps, the button is located on the
instrument panel, to the right of the steering wheel.
The ignition must be on to use the fog lamps.
#:Press to turn the fog lamps on and off. An indicator
light on the button comes on when the fog lamps are on.
The parking lamps automatically turn on and off when the
fog lamps are turned on and off.
The fog lamps will turn off while the high-beam
headlamps are turned on.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
