Daytime Running Lamps / Automatic
Headlamp Control
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 dnving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.
A light sensor on top of the instrument panel makes
the DRL work,
so be sure it isn’t covered.
The DRL system will make your high-beam headlamps
come on at a reduced brightness when:
The ignition is on,
The headlamp switch is off and
The parking brake is released.
97LUMWCARL0001 When
the DRL
are on, only your reduced intensity
high-beam headlamps will be on. The taillamps,
sidemarker and other lamps won’t be on. Your
instrument panel won’t be
lit up either.
When it’s dark enough outside, your DRL will turn off
and your low-beam headlamps will turn on. The other
lamps that come on with your headlamps will also
come on.
When it’s bright enough outside, the low-beam
headlamps will go out and DRL turns on your
high-beam headlamps at reduced intensity.
To idle your vehicle with the DRL off, set the parking
brake while the ignition is in
OFF or LOCK. Then start
your vehicle. The DRL will stay off until you release
the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

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 readmess
of the system, when the sensors are
activated and driver’s safety
belt usage at deployment.
Let only qualified technicians work on your
air bag system. Improper service can mean that
your air bag system won’t 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.
Servicing Your Air Bag-Equipped
Chevrolet
Air bags affect how your Chevrolet should be serviced.
There are parts of the air bag system in several places
around your vehicle. You don’t want the system to
inflate while someone is working on your vehicle. Your
Chevrolet dealer and the Monte Carlo Service Manual
have information about servicing your vehicle and the
air bag system.
To purchase a service manual, see
“Service and Owner Publications”
in the Index.
For up to 10 minutes after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured
if you are close to an air bag when
it inflates. Avoid wires wrapped with yellow tape
or yellow connectors. They are probably part of
the air bag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualified to do
so.
The air bag system does not need regular maintenance.

Downloaded from www.Manualslib.com manuals search engine Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR
BAG or 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, see “Air Bag” in the Index.
AIR BAG
This light will come on
when you start your engine,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready. The
air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN.
If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you if there is a problem.
Charging System Light
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
VOLTS
The charging system light
will come on briefly when
you turn on the ignition, as
a check to show you it’s
working. Then it should
go out.
If
it stays on, or comes on while you are driving, you
may have a problem with the charging system. It could
indicate that you have a loose drive ‘belt or another
electrical problem. Have it checked right away. Driving
while this light is on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn
off all your accessories, such as the radio
and air conditioner.

Downloaded from www.Manualslib.com manuals search engine If you make a hard stop, the light may come on for a
moment. This is normal. Low Oil Level Light
Don’t keep driving if the oil pressure is low. If
you do, your engine can become
so hot that it
catches fire.
You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
LOW
OIL
Your engine is equipped
with an oil level monitoring
system. When the ignition
key is turned on, the LOW
OIL light will briefly flash.
If the light does not flash,
have it fixed
so it will be
ready to warn you if there’s a problem.
If the light stays on, stop the vehicle on a level surface
and turn the engine off. Check the oil level using the
engine oil dipstick. (See “Engine Oil’’ in the Index.) If
the light does not flash, have the low oil level sensor
system repaired
so it will be ready to warn you if there’s
a problem.
The oil level monitoring system only checks the oil level
during the brief period between key
on and engine
crank. It does not monitor the engine oil level when the
engine is running. Additionally, an oil level check
is
only performed if the engine has been turned off for a
considerable period
of time, allowing the oil normally in
circulation to drain back into the oil pan.
