Daytime Running Lamps (DRL) /
Automatic Headlamp System
Daytime Running Lamps (BRL) can make it easier for
others
to see the front of y~ur 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
first sold in Canada.
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 low-beam headlamps
come on at a reduced brightness when the following
conditions are met:
The ignition is on,
0 the exterior lamps control is off,
0 the transaxle is not in PARK (P) and
the parking brake is released. When
the DRL are on, only your low-beam headlamps,
at a reduced brightness, 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 headlamps
will
change to full brightness. The other lamps that come on
with your headlamps will also come on.
When it’s bright enough outside, the headlamps will go
out, and your low-beam headlamps will change to
the reduced brightness of DRL.
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 shift
out of PARK (P) and release the parking brake.
As with any vehicle, you should turn on the regular
headlamps system when you need
it.

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts.
If one part isn’t working, the other part can still
work and stop you. For good braking, though, you
need both parts working well.
If the light comes on while you are driving, carefully pull
off the road and stop. You may notice that the pedal
is harder to push. Or, the pedal may go closer to
the floor. It may take longer to stop.
If the light is still
on, have the vehicle towed for service. See Towing
Your
Vehicle on page 4-33.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.

This light should come on when you turn the key to
RUN. If it doesn’t come on then, have it fixed so it will
be ready to warn you
if there’s a problem.
Your oraKe system may not be working
properly
if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you’ve pulled off the road and stopped
carefully, have the vehicle towed for service.
While the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on
if your parking brake doesn’t
release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.

Anti-Lock Brake System Warning Light
if your vehicle has the
optional anti-lock brake
system, this light will come
on when your engine is
started and may stay on
for several seconds.
That’s normal.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition
off. If the light comes on and stays on
while you’re driving, stop as soon as possible and turn
the ignition
off. Then start the engine again to reset
the system.
If the light still stays on, or comes on again
while you’re driving, your vehicle needs service.
If
the light is on and the regular brake system warning
light isn’t on, you still have brakes, but you don’t have
anti-lock brakes.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to
RUN. This is
normal.
If the light doesn’t come on then, have it
fixed
so it will be ready to warn you if there is a problem.
Traction Control System (TCS)

If you turn the system off by pressing the TCS
button located on the far right side of the trip
computer, the warning light will come on and stay
on. To turn the system back on, press the button
again. The warning light should go

4-10 for more
information.
@ If there’s a brake system problem that is specifically
related to traction control, the traction control
system will turn
off and the warning light will come
on. If your brakes begin to overheat, the traction
control system will turn
off and the warning light will
come on until your brakes cool down.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system
is turned on, your vehicle needs service.

TRAC
If your vehicle has the
Enhanced Traction
System or the Traction
Control System, this light
will also come on while
the system is limiting
wheel spin.
You may feel or hear the system working, but this is
normal. Slippery road conditions may exist
if the
low traction light comes on,
so adjust your driving
accordingly. The light will stay on for a few seconds after
the Enhanced Traction System or the Traction Control
System stops limiting wheel spin. See Enhanced
Traction System
(ETS) on page 4-1 1 or Traction Control
System (TCS) on page
4- 10.
The low traction light also comes on briefly when you
turn the ignition key to RUN. If the light doesn’t come on
then, have it fixed so it will be there to tell you when
the Traction Control System or Enhanced Traction
System is active.

The Driver Information Center (DIC) gives you important
safety and maintenance facts. When you turn the
ignition on, all of the DIC lights illuminate for a few
seconds. After this, the DIC will begin working.
Functions
__ (Door Ajar): If one of the doors is ajar, this light
will appear next to that door on the vehicle outline.
CHANGE OIL SOON: This light will appear when the
system indicates that it’s time for an oil change. The
system predicts remaining oil life using data from length
of drives, coolant temperature, engine rpm and
vehicle speed. It alerts you to change the oil on a
schedule consistent with the vehicle’s driving conditions.
After changing the oil, the system must be reset. See
How to Reset the GM
Oil Life SystemTM under
Engine
Oil on page 5- 18.
e LOW: This light will come on when the ignition is
on and the fluid in the washer fluid container is low.
AJAR: This light alerts you that the trunk is not
fully closed.
LOW TRAC (Low Traction): If your vehicle is equipped
with anti-lock brakes, this light will come on when the
enhanced traction system is limiting wheel spin. See Enhanced Traction System (ETS) on page 4-
I I or
Low Traction Light on page 3-30.
TRAC OFF (Traction Off): If your vehicle is equipped
with anti-lock brakes, this light lets you know that
the enhanced traction system has been disabled and
will not limit wheel spin. See Enhanced Traction System
Warning Light
on page 3-30 or Low Traction Light on
page 3-30.
TRAC (Traction): If the vehicle has anti-lock brakes
and the enhanced traction system, you will have a
disable button on the far right side of the DIC.
The enhanced traction system is automatically activated
when you turn the ignition on. This button will
activate/deactivate the system. If you need to disable
the system, such
as when you are stuck and are rocking
the vehicle back and forth, push this button. See If
You Are Stuck: in Sand, Mud, Ice or Snow on
page 4-32.
