airbag CHEVROLET COLORADO 2007 1.G Service Manual

Airbag Readiness Light
There is an airbag readiness light on the
instrument panel, which shows the airbag symbol.
The system checks the airbag’s electrical system
for malfunctions. The light tells you if there is
an electrical problem. The system check includes
the airbag sensors, the airbag modules, the
wiring and the crash sensing and diagnostic
module. For more information on the airbag
systems, seeAirbag System on page 77.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should go
out. This means the
system is ready.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced
right away if the airbag readiness light
stays on after you start your vehicle.
The airbag readiness light should ash for a
few seconds when you turn the ignition key to ON.
If the light does not come on then, have it xed
so it will be ready to warn you if there is a problem.

Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system.
Your instrument panel has a passenger airbag
status indicator.
When the ignition key is turned to ON or START,
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 airbag.There is a label on your sun visor that says,
“Never put a rear-facing child seat in the front.”
This is because the risk to the rear-facing child
is so great if the airbag deploys.
{CAUTION:
Even though the passenger sensing
system is designed to turn off the right
front passenger’s frontal airbag if the
system detects a rear-facing child restraint,
no system is fail-safe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend that
rear-facing child restraints be secured in
the rear seat, even if the airbag is off.

186

If your vehicle does not have a rear seat that will
accommodate a rear-facing child restraint, never
put a child in a rear-facing child restraint in the right
front passenger seat unless the passenger airbag
status indicator shows off and the airbag is off.
Here is why:
{CAUTION:
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint,
no system is fail-safe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend that
rear-facing child restraints be transported
in vehicles with a rear seat that will
accommodate a rear-facing child restraint,
whenever possible.If the word ON or the on symbol is lit on the
passenger airbag status indicator, it means that
the right front passenger’s frontal airbag is enabled
(may inate).
{CAUTION:
If the on indicator comes on when you
have a rear-facing child restraint installed
in the right front passenger’s seat, it
means that the passenger sensing system
has not turned off the passenger’s frontal
airbag. A child in a rear-facing child
restraint can be seriously injured or
killed if the right front passenger’s airbag
inates. This is because the back of the
rear-facing child restraint would be very
close to the inating airbag. Do not use
a rear-facing child restraint in the right
front passenger’s seat if the airbag is
turned on.
187

If the word OFF or the off symbol is lit on the
airbag status indicator, it means that the
passenger sensing system has turned off the right
front passenger’s frontal airbag. SeePassenger
Sensing System on page 88for more on this,
including important safety information.
If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together,
it means that something may be wrong
with the airbag system. If this ever
happens, have the vehicle serviced
promptly, because an adult-size person
sitting in the right front passenger seat
may not have the protection of the frontal
airbag. SeeAirbag Readiness Light
on page 185.
Battery Warning Light
This light will come
on briey when you
start the vehicle,
as a check to show
you it is working;
then it should go out.
If it stays on, or comes on while you are driving,
you may have a problem with the electrical
charging system. Have it checked right away.
Driving while this light is on could drain your
battery and result in a vehicle that may stall.
SeeDIC Warnings and Messages on page 202
for more information.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and climate control system.

The airbag system is designed to work properly
under a wide range of conditions, including off-road
usage. Observe safe driving speeds, especially
on rough terrain. As always, wear your safety belt.
Off-road driving can be great fun. But it does
have some denite hazards. The greatest of
these is the terrain itself.
“Off-roading” means you have left the great
North American road system behind. Traffic lanes
are not marked. Curves are not banked. There
are no road signs. Surfaces can be slippery, rough,
uphill, or downhill. In short, you have gone right
back to nature.
Off-road driving involves some new skills. And
that is why it is very important that you read
this guide. You will nd many driving tips and
suggestions. These will help make your off-road
driving safer and more enjoyable.Before You Go Off-Roading
There are some things to do before you go out.
For example, be sure to have all necessary
maintenance and service work done. Check to
make sure all underbody shields, if the vehicle
has them, are properly attached. Be sure you
read all the information about your four-wheel-drive
vehicle in this manual. Is there enough fuel?
Is the spare tire fully inated? Are the uid levels
up where they should be? What are the local
laws that apply to off-roading where you will be
driving? If you do not know, you should check
with law enforcement people in the area. Will you
be on someone’s private land? If so, be sure
to get the necessary permission.
