Headlamps on Reminder
If a door is open, a reminder chime will sound when
the headlamps or parking lamps are manually
turned on and your key is out of the ignition. To turn
off the chime, turn the headlamp switch to off and
then back on. In the automatic mode, the
headlamps turn off once the ignition is in LOCK.
If your vehicle was rst sold in Canada and the
parking lamps are turned on manually, the Daytime
Running Lamps (DRL) will stay on.
Daytime Running Lamps (DRL)
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 come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in PARK (P) if you
have an automatic transmission.
The light sensor determines it is daytime.
Your vehicle will have either the parking lamps or
reduced intensity low beams used as the DRL.
When the DRL are on, only those lamps will be on.
The taillamps, sidemarkers, and other lamps will
not be on. The instrument panel will not be lit
up either.
When it begins to get dark, the headlamps will
automatically switch from DRL to the regular
headlamps.
As with any vehicle, you should turn on the
regular headlamp system when you need it.

Automatic Headlamp System
When it is dark enough outside, the automatic
headlamp system will turn on after the
transmission has been shifted from PARK (P) to
DRIVE (D). The headlamps, taillamps, sidemarker,
parking lamps, roof marker lamps, and the
instrument panel lights will turn on at normal
brightness. The radio lights will become more dim
when the headlights are off compared to when
the headlights are on.
Your vehicle has a light sensor located 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 the headlamps 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 system 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
detects a change in lighting lasting longer than
the delay.
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 about one minute for the automatic headlamp
system to change to DRL if it is light outside.
During that delay, the instrument panel cluster
may not be as bright as usual. Make sure
the instrument panel brightness control is in the
full bright position. SeeInstrument Panel
Brightness on page 170.

Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You will
know how fast you are going, about how much fuel you have used, and many other things you will need to
know to drive safely and economically.

Up-Shift Light
(Manual Transmission)
This light appears when
you need to shift to the
next higher gear on
a manual transmission
vehicle.
Shifting when the indicator light is on will help you
get the best fuel economy. See “Up-Shift Light”
underManual Transmission Operation on
page 124for more information.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the other
part can still work and stop you. For good
braking, though, you need both parts working well.
If the warning light comes on, there could be a
brake problem. Have your brake system inspected
right away.
This light should come on brie y when you turn
the ignition key to ON. If it does not come on then,
have it xed so it will be ready to warn you if
there is a problem.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation of
the fuel, ignition,
and emission control
systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable
levels for the life of the vehicle, helping to produce
a cleaner environment. The check engine light
comes on to indicate that there is a problem and
service is required. Malfunctions often will be
indicated by the system before any problem is
apparent. This may prevent more serious damage
to your vehicle. This system is also designed to
assist your service technician in correctly
diagnosing any malfunction.Notice:If you keep driving your vehicle with
this light on, after awhile, your emission
controls may not work as well, your fuel
economy may not be as good, and your engine
may not run as smoothly. This could lead to
costly repairs that may not be covered by your
warranty.
Notice:Modi cations made to the engine,
transmission, exhaust, intake, or fuel system
of your vehicle or the replacement of the
original tires with other than those of the same
Tire Performance Criteria (TPC) can affect
your vehicle’s emission controls and may
cause this light to come on. Modi cations to
these systems could lead to costly repairs
not covered by your warranty. This may also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 316.

Remember: ABS does not change the time you
need to get your foot up to the brake pedal or
always decrease stopping distance. If you get too
close to the vehicle in front of you, you will not have
time to apply your brakes if that vehicle suddenly
slows or stops. Always leave enough room up
ahead to stop, even though you have ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let anti-lock work for you. You may
feel the brakes vibrate, or you may notice some
noise, but this is normal.
Braking in Emergencies
With ABS, you can steer and brake at the same
time. In many emergencies, steering can help you
more than even the very best braking.
Traction Control System (TCS)
Your vehicle may have a Traction Control
System (TCS) that limits wheel spin. This is
especially useful in slippery road conditions.
The system operates only if it senses that one
or both of the rear wheels are spinning or
beginning to lose traction. When this happens,
the system reduces engine power and may
also upshift the transmission to limit wheel spin.
You may feel or hear the system working, but this
is normal.
The TCS button is
located on your
instrument panel.
Press this button
to turn the TCS
off and on.
When the traction control system is turned off, an
indicator light on the button will illuminate.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the
cruise control will automatically disengage.
249
Page 250 of 492

When road conditions allow you to safely use it
again, you may re-engage the cruise control.
SeeCruise Control on page 163.
TCS operates in all transmission shift lever
positions. But the system can upshift the
transmission only as high as the shift lever position
you have chosen, so you should use the lower
gears only when necessary. SeeAutomatic
Transmission Operation on page 120and/or
Manual Transmission Operation on page 124for
more information.
If there is a problem with TCS, TRACTION FAULT
will be displayed on your Driver Information
Center (DIC). SeeDIC Warnings and Messages
on page 198for more information.
When this warning is displayed, the system will
not limit wheel spin. Adjust your driving
accordingly.
To limit wheel spin, especially in slippery road
conditions, you should always leave TCS on.
But you can turn the system off if you ever
need to. You should turn the system off if
your vehicle ever gets stuck in sand, mud or
snow and rocking the vehicle is required.SeeRocking Your Vehicle to Get It Out on
page 284andIf Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow on page 284for more
information.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modi cations on page 316for more information.
Limited-Slip Rear Axle
If your vehicle has this feature, your limited-slip
rear axle can give you additional traction on snow,
mud, ice, sand or gravel. It works like a standard
axle most of the time, but when one of the
rear wheels has no traction and the other does,
this feature will allow the wheel with traction
to move the vehicle.
Steering
Power Steering
If you lose power steering assist because the
engine stops or the system is not functioning, you
can steer but it will take much more effort.
