2004 CHEVROLET TRACKER sensor

In many crashes severe enough to in¯ate the air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.
·Air bags are designed to in¯ate only once. After an
air bag in¯ates, you will need some new parts for
your air bag system. If you do not get them, the air
bag system will not be there to help protect you
in another crash. A new system will include air bag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
·Your vehicle is equipped with a crash sensing and
diagnostic module, which records information
about the air bag system. The module records
information about the readiness of the system, when
the system commands air bag in¯ation and
driver's safety belt usage at deployment.
·Let only quali®ed technicians work on your air bag
systems. Improper service can mean that an air
bag system will not work properly. See your dealer
for service.
Notice:If you damage the covering for the driver's
or the right front passenger's air bag, the bag
may not work properly. You may have to replace the
air bag module in the steering wheel or both the
air bag module and the instrument panel for
the right front passenger's air bag. Do not open or
break the air bag coverings.
If your vehicle ever gets into a lot of water ± such as
water up to the carpeting or higher ± or if water enters
your vehicle and soaks the carpet, the air bag
controller can be soaked and ruined. If this ever
happens, and then you start your vehicle, the damage
could make the air bags in¯ate, even if there is no crash.
You would have to replace the air bags as well as the
sensors and related parts. If your vehicle is ever in
a ¯ood, or if it is exposed to water that soaks the carpet,
you can avoid needless repair costs by turning off the
vehicle immediately and disconnecting the battery
cables. Do not let anyone start the vehicle under any
circumstances. See your dealer for service.

Adding Equipment to Your Air
Bag-Equipped Vehicle
Q:If I add a push bumper or a bicycle rack to the
front of my vehicle, will it keep the air bags
from working properly?
A:As long as the push bumper or bicycle rack is
attached to your vehicle so that the vehicle's
basic structure isn't changed, it's not likely to keep
the air bags from working properly in a crash.
Q:Is there anything I might add to the front of the
vehicle that could keep the air bags from
working properly?
A:Yes. If you add things that change your vehicle's
frame, bumper system, front end sheet metal or
height, they may keep the air bag system
from working properly. Also, the air bag system
may not work properly if you relocate any of the air
bag sensors. If you have any questions about
this, you should contact Customer Assistance
before you modify your vehicle. The phone
numbers and addresses for Customer Assistance

Customer Satisfaction

Restraint System Check
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)

Automatic Headlamp System
Your vehicle is equipped with an automatic light sensor
on top of the instrument panel, on the passenger's
side of the vehicle, so be sure it is not covered. If it is,
the headlamps will remain on continuously.
There is a delay in the transition between the daytime
and nighttime operation of the DRL and the Automatic
Headlamp Systems so that driving under bridges or
bright overhead street lights does not affect the system.
The DRL and Automatic Headlamp Systems will only
be affected when the light sensor sees a change
in lighting lasting longer than this delay.
When it is dark enough outside, or you are driving
through a parking garage, heavy overcast weather or a
tunnel, the system will turn on your low-beam
headlamps at normal brightness. Along with your
vehicle's headlamps, the taillamps, sidemarker, parking
lamps and the instrument panel lights will also turn
on. The radio display will dim.
As with any vehicle, you should turn on the regular
headlamps when you need them.
To temporarily disable your vehicle's DRL and Automatic
Headlamp Systems functions, do the following:
1. Before turning the ignition key to ON or START, set
the parking brake.2. Then turn the ignition key to ON or START.·The Automatic Headlamp System will not turn on
under any conditions, even in darkness.
·The DRL will not turn on.
The DRL and Automatic Headlamp System functions
will stay off with the ignition on, until you release
the parking brake. Once the parking brake is released
the DRL will turn on if it is daylight or the Automatic
Headlamp System will turn on if it is dark enough
outside.
If you turn the ignition key to ON or START and then
set the parking brake, the DRL will turn off (in all
conditions) and the Automatic Headlamp System will
remain on (if dark enough outside). Any other uses
of the parking brake after the engine is turned on will
have no effect on the normal Automatic Headlamp
System operation.
Headlamps On Reminder
If you turn the ignition off, remove the key, open the
door and leave the lamps on, a tone will remind you to
turn off your lamps.
