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,
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’s 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). See
Passenger Sensing System
on page 1-30.
If you have any questions about
this, you should contact Customer
Assistance before you modify
your vehicle. The phone numbersand addresses for Customer
Assistance are in Step Two of the
Customer Satisfaction Procedure
in this manual. SeeCustomer
Satisfaction Procedure on
page 11-1.
Q:Because I have a disability,
I have to get my vehicle
modied. How can I nd out
whether this will affect my
airbag system?
A: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.
SeeCustomer Satisfaction
Procedure on page 11-1.
In addition, your dealer/retailer and
the service manual have information
about the location of the airbag
sensors, sensing and diagnostic
module and airbag wiring.

Cruise Control
{CAUTION
Cruise control can be
dangerous where you cannot
drive safely at a steady speed.
So, do not use your 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.With cruise control, a speed of about
25 mph (40 km/h) or more can be
maintained without keeping your foot
on the accelerator. This can really
help on long trips. Cruise control
does not work at speeds below
about 25 mph (40 km/h).
The cruise control buttons
are located on the turn signal/
multifunction lever on the left
side of the steering wheel.
9(On/Off):Press and hold the
button on the back end of the cruise
control lever, to turn the cruise
control system on or off. The CC
on or CC off message will appear on
the instrument panel cluster at the
odometer display to show that the
cruise control system is on or off.

Trip Computer
The vehicle may have a trip
computer. The trip computer
provides information on driving
data. This information is continually
recorded and evaluated
electronically. If power has been
interrupted or if the battery voltage
has dropped too low, the values
stored in the trip computer will
be lost.
To access trip computer vehicle
data, do one of the following:
Press the BC button on the audio
system.
Press the left thumbwheel, if your
vehicle has this feature, on the
steering wheel.
Once an audio function has been
selected, the rows of the trip
computer function are displayed.The functions are displayed in the
following order:
Instantaneous Consumption
This display shows the current fuel
economy at a particular moment
and will change frequently as driving
conditions change. This display
shows the instantaneous fuel
economy in miles per gallon (mpg) or
liters per 100 kilometers (l/100 km).
The metric display changes
depending on speed:
Below 8 mph (13 km/h), displays
in l/h.
Above 8 mph (13 km/h), displays
in l/100 km.
This screen cannot be reset.Average Consumption
This display shows the approximate
average miles per gallon (mpg) or
liters per 100 kilometers (l/100 km).
This number is calculated based
on the number of mpg (l/100 km)
recorded since the last time this
menu item was reset.
The measurement can be reset to
zero at any time and restarted.
See “Reset” later in this section.
Trip Consumption
This display shows the number of
gallons (gal) or liters (l) of fuel
used since the last reset.
The measurement can be reset to
zero at any time and restarted.
See “Reset” later in this section.
Instruments and Controls 4-29
ProCarManuals.com

Average Speed
This display shows the average
speed of the vehicle in miles
per hour (mph) or kilometers
per hour (km/h). This average is
calculated based on the various
vehicle speeds recorded since
the last reset of this value.
The measurement can be reset to
zero at any time and restarted.
See “Reset” later in this section.
Distance Travelled
This display shows the current
distance traveled in either miles (mi)
or kilometers (km) since the last
reset.
The measurement can be reset to
zero at any time and restarted.
See “Reset” later in this section.Range
This display shows the approximate
number of remaining miles (mi)
or kilometers (km) the vehicle
can be driven without refueling.
The message “Range” displays
if less than 31 mi (50 km) can be
driven with the fuel remaining in the
tank. The message “Refuel!” displays
when approximately 19 mi (30 km)
can be driven with the fuel remaining
in the tank. With less than 19 mi
(30 km) worth of fuel remaining the
range display will show “- -” once
the “Refuel!” message has been
acknowledged.
SeeDIC Warnings and Messages
(Base and Uplevel Systems) on
page 4-37for information on
acknowledging the message.
The fuel range estimate is based
on an average of the vehicle’s fuel
economy over recent driving history
and the amount of fuel remainingin the fuel tank. This estimate will
change if driving conditions change.
For example, if driving in traffic and
making frequent stops, this display
may read one number, but if the
vehicle is driven on a freeway, the
number may change even though
the same amount of fuel is in the
fuel tank. This is because different
driving conditions produce different
fuel economies. Generally, freeway
driving produces better fuel economy
than city driving. Fuel range cannot
be reset.
Stop Watch
This display can be used as a timer.
To start or stop the timer, press
the right arrow on the audio system.
To reset the timer, press the left
arrow until the value returns to zero.
If your vehicle has the left
thumbwheel on the steering wheel,
you can start or stop the timer
by pressing the thumbwheel.

DIC Warnings and
Messages (Base and
Uplevel Systems)
Messages are displayed on the DIC
to notify the driver that the status of
the vehicle has changed and that
some action may be needed by
the driver to correct the condition.
Multiple messages may appear
one after another.
The DIC monitors some uid levels,
battery of the Remote Keyless Entry
(RKE) transmitter, the theft-deterrent
system on vehicles with this feature,
the brake light switch, and important
exterior lights, including wiring and
fuses.Some messages may not require
immediate action, but you can
acknowledge that you received the
messages and to clear them from the
display by doing one of the following:
Press the OK button on the base
level audio system.
Press the multifunction knob, if
your vehicle has this feature,
on the uplevel audio system.
Press the left thumbwheel, if your

from the DIC display because they
are more urgent. These messages
require action before they can
be cleared. You should take any
messages that appear on the display
seriously and remember that clearing
the messages will only make the
messages disappear, not correct
the problem.
Warning messages for the uplevel
DIC follow. On the base level
DIC, messages appear in an
abbreviated form.
Brakelight check---
This message displays when there
is a problem with the vehicle lighting.
The source of the problem is

If your vehicle’s engine ever stops
while you are driving, brake normally
but do not pump the brakes. If you
do, the pedal could get harder to
push down. If the engine stops, you
will still have some power brake
assist. But you will use it when you
brake. Once the power assist is used
up, it can take longer to stop and the
brake pedal will be harder to push.
Adding non-dealer/non-retailer
accessories can affect your vehicle’s
performance. SeeAccessories
and Modifications on page 9-3.Antilock Brake
System (ABS)
Your vehicle has the Antilock
Brake System (ABS), an advanced
electronic braking system that
will help prevent a braking skid.
When you start the engine and
begin to drive away, ABS will check
itself. You might hear a momentary
motor or clicking noise while this
test is going on, and you might even
notice that the brake pedal moves a
little. This is normal.
If there is a problem with ABS,
this warning light will stay on.
SeeAntilock Brake System (ABS)
Warning Light on page 4-18.Let us say the road is wet and you
are driving safely. Suddenly, an
animal jumps out in front of you.
You slam on the brakes and
continue braking. Here is what
happens with ABS:
A computer senses that wheels
are slowing down. If one of
the wheels is about to stop rolling,
the computer will separately
work the brakes at each wheel.
ABS can change the brake
pressure faster than any driver could.
The computer is programmed to
make the most of available tire and
road conditions. This can help you
steer around the obstacle while
braking hard.
As you brake, the computer keeps
receiving updates on wheel speed
and controls braking pressure
accordingly.
