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 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 Buick
Air bags affect how your Buick 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
Buick dealer and the Century 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.
I
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.

AUTOMATIC OVERDRIVE (@): This position is for
normal driving. If you need more power for passing,
and you’re:
Going less than 35 mph (56 km/h), push your

pedal about halfway down.
accelerator pedal all the way down.
You’ll shift down

more power.
NOTICE:
I
If your vehicle seems to start up rather slowly, or
if it seems not to shift gears as you go faster,
something may be wrong with a transaxle system
sensor.
If you drive very far that way, your
vehicle can be damaged.
So, if this happens, have
your vehicle serviced right away. Until then, you
can use
SECOND (2) when you are driving less
than
35 mph (56 kmh) and AUTOMATIC
OVERDRIVE (a) for higher speeds. THIRD
(3): This
position is also used for normal
driving, but it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE
(0).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (0):
0 When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
When going down a steep hill.
0 When driving in non-highway scenarios (i.e. city
between
gears.

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 driving
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 front turn signal lamps
come on when:
0 The ignition is on,
The headlamp switch is off and
0 The parking brake is released.
When the DRL are on, only your your front turn signal
lamps will be on. The headlamps, 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 front turn signal
lamps will turn off and your vehicle’s headlamps and
parklamps will turn on. The other lamps that come on
with your headlamps will also come on.
When it’s bright enough outside, your headlamps will go
off and your front turn signal lamps will come on.
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, headlamps and parklamps 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.

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 come on
briefly.
If the light does not
come on briefly, 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 oil level
during the brief period between key
on and engine
crank.
It does not monitor 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.
