sensor CHEVROLET SSR 2004 1.G Owners Manual

Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the air
bags inate (if battery power is available). You can lock
the doors again and turn the interior lamps off by
using the door lock and interior lamp controls.
In many crashes severe enough to inate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
passenger air bag.
Air bags are designed to inate only once. After an
air bag inates, you’ll need some new parts for
your air bag system. If you don’t get them, the air
bag system won’t 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 electronic frontal
sensors, which help the sensing system distinguish
between a moderate frontal impact and a more
severe frontal impact. Your vehicle is also equipped
with a crash sensing and diagnostic module,
which records information about the frontal air bag
system. The module records information about
the readiness of the system, when the system
commands air bag ination and driver’s safety belt
usage at deployment. The module also records
speed, engine RPM, brake and throttle data. See
Vehicle Data Collection and Event Data Recorders
on page 7-10for more information.
Let only qualied technicians work on your air bag
systems. Improper service can mean that an air
bag system won’t work properly. See your dealer for
service.
Notice:If you damage the covering for the driver’s
or the 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
passenger’s air bag. Do not open or break the air
bag coverings.

Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps and the
instrument panel lights when the exterior lamps knob is
turned to AUTO. The radio lights will also be on.
Your vehicle is equipped with a light sensor on the top
of the instrument panel. Be sure it is not covered or
the system will be on whenever the ignition is on.
The system may also turn on your lights when driving
through a parking garage, heavy overcast weather
or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (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 system will only be affected when
the light sensor sees a change in lighting lasting
longer than the delay.
To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is off.
Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake,
or until you shift out of PARK (P).You may be able to turn off your automatic headlamp
system. See “Daytime Running Lamps (DRL)” later
in this section for more information.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage, it will take approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
control is in the full bright position. See “Instrument
Panel Brightness” underInterior Lamps on page 3-15.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Lamps On Reminder
A reminder tone will sound when your headlamps or
parking lamps are manually turned on, the driver’s door
is open and your ignition is in OFF or ACCESSORY.
To turn the tone off, turn the knob all the way
counterclockwise. In the automatic mode, the headlamps
turn off once the ignition key is in OFF.

Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
rst sold in Canada.
The DRL system will make your headlamps come on
at reduced brightness when the following conditions
are met:
The ignition is on.
The exterior lamps knob is in AUTO.
The light sensor detects daytime light.
The transmission is not in PARK (P).
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won’t be
on. The instrument panel won’t be lit up either.
When it begins to get dark, the headlamps will
automatically switch from DRL to the regular headlamps.
To idle your vehicle with the DRL off, put your vehicle’s
transmission in PARK (P). The DRL will stay off until
you shift out of PARK (P).
Fog Lamps
Use your fog lamps for better vision in foggy or misty
conditions. Your ignition must be in RUN for your
fog lamps to work.
-(Fog Lamps):Press this button located on the
exterior lamps control to turn the fog lamps on or off.
The fog lamps will go off whenever you turn on the
high-beam headlamps. When the high beams are turned
off, the fog lamps will come on again.
O(Fog Lamp Indicator Light):This light located on
the exterior lamps control illuminates when the fog
lamps are turned on.

Exit Lighting
With the exit lighting, the interior lamps will come on
when you remove the key from the ignition to help you
see while exiting the vehicle.
Parade Dimming
This feature prohibits the dimming of your instrument
panel displays during daylight while your headlamps are
on. When the light sensor reads darkness outside,
you will be able to dim your instrument panel displays
once again.
Perimeter Lighting
When the button with the unlock symbol on the remote
keyless entry transmitter is pressed, the DRL, parking
lamps and back-up lamps will come on if it is dark
enough outside.
This feature can be personalized for up to two drivers.
SeeDIC Vehicle Personalization on page 3-55for
more information.
Front Map Lamps
If your vehicle has front map lamps, they are located on
the inside rearview mirror. They will automatically
come on for about 40 seconds when the doors are
unlocked with the remote keyless entry transmitter or
until the ignition key is turned to RUN or ACCESSORY.
The lamps will also stay on for about 40 seconds
after you exit the vehicle unless you lock the doors with
the remote keyless entry transmitter.
You can also turn the lamps on and off by pressing the
button near each lamp.
Battery Rundown Protection
This feature shuts off all lamps that are left on for more
than 10 minutes when the ignition is off. This will
keep your battery from running down.
3-16

Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for several seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay
on for several seconds,
then it will ash for
several more.
If the driver’s belt is already buckled, neither the chime
nor the light will come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel cluster, which shows the air bag symbol.
The system checks the air bag’s electrical system for
malfunctions. The light tells you if there is an electrical
problem. The system check includes the air bag
sensors, the air bag modules, the wiring and the crash
sensing and diagnostic module. For more information
on the air bag system, seeAir Bag Systems on
page 1-42.
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.
