Headlamps on Reminder
A reminder chime 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 chime 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 (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
first sold in Canada.The DRL system will make your headlamps come on
at reduced brightness when the following conditions
are met:
•Ignition is on.
•Exterior lamps knob is in AUTO.
•Light sensor detects daytime light.
•Automatic transmission is not in PARK (P).
•The parking brake is not set.
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.
3-14
To idle your vehicle with the DRL off, set the parking
brake when the ignition is off and then start your vehicle.
The DRL will stay off until you release the parking brake.
In DRL mode further cycling of the park brake will
do the following if your vehicle was made in the
United States:
•If your vehicle has an automatic transmission,
pulling up the parking brake and then releasing
it will turn on the DRL. If you repeat this, the DRL
will turn off and stay off. This applies to the
automatic headlamps as well.
•If your vehicle has a manual transmission, pulling
the parking brake up will turn off the DRLs. If the
parking brake is released, the DRLs will turn
on. After the first cycle of the park brake, the
automatic headlamps will stay on and the system
does not respond to further cycling of the park brake
until the next time you turn on your vehicle.
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. SeeExterior Lamps on page 3-13
for more information. 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. SeeDaytime Running Lamps
(DRL) on page 3-14for more information.
3-15
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. SeeDaytime Running Lamps (DRL) on
page 3-14for 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. SeeInstrument Panel
Brightness on page 3-17for more information.
As with any vehicle, you should turn on the regular
headlamp system when you need it.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.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
3-16
Charging System Light
The charging system light
will come on briefly when
you turn on the ignition,
but the engine is not
running, as a check to
show you it is working.
It should go out once the engine is running. 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 problems with a generator 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.
Brake System Warning Light
When the ignition is on, the brake system warning light
will come on when you set your parking brake. See
Parking Brake on page 2-23for more information. 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.
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 warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
This light should come on briefly when you turn the
ignition 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.

{CAUTION:
This system provides you with a far greater
access to audio stations and song listings.
Giving extended attention to entertainment
tasks while driving can cause a crash and you
or others can be injured or killed. Always keep
your eyes on the road and your mind on the
drive — avoid engaging in extended searching
while driving.
Keeping your mind on the drive is important for safe
driving. For more information, seeDefensive Driving on
page 4-2.
Here are some ways in which you can help avoid
distraction while driving.
While your vehicle is parked:
•Familiarize yourself with all of its controls.
•Familiarize yourself with its operation.
•Set up your audio system by presetting your
favorite radio stations, setting the tone, and
adjusting the speakers. Then, when driving
conditions permit, you can tune to your favorite
radio stations using the presets and steering wheel
controls (if equipped).Notice:Before adding any sound equipment to
your vehicle, such as an audio system, CD player,
CB radio, mobile telephone, or two-way radio, make
sure that it can be added by checking with your
dealer. Also, check federal rules covering mobile
radio and telephone units. If sound equipment can
be added, it is very important to do it properly.
Added sound equipment may interfere with
the operation of your vehicle’s engine, radio, or
other systems, and even damage them. Your
vehicle’s systems may interfere with the operation
of sound equipment that has been added.
Notice:The chime signals related to safety belts,
parking brake, and other functions of your vehicle
operate through the GM radio/entertainment system.
If that equipment is replaced or additional
equipment is added to your vehicle, the chimes may
not work. Make sure that replacement or additional
equipment is compatible with your vehicle before
installing it. SeeAccessories and Modifications on
page 5-3.

Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
If you have an automatic transmission, you can tow in
DRIVE (D). You may want to shift the transmission
to THIRD (3) or, if necessary, a lower gear if the
transmission shifts too often under heavy loads or hilly
conditions. If you have a manual transmission and
you are towing a trailer, it is better not to use SIXTH (6)
gear. Just drive in FIFTH (5) gear (or, as you need
to, a lower gear).
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a lower
temperature than at normal altitudes. If you turn your
engine off immediately after towing at high altitude
on steep uphill grades, your vehicle may show signs
similar to engine overheating. To avoid this, let the
engine run while parked, preferably on level ground, with
the automatic transmission in PARK (P) for a few
minutes before turning the engine off. For manual
transmissions, let the engine run while parked,
preferably on level ground, with the transmission out of
gear and the parking brake applied, for a few minutes
before turning the engine off. If you do get the overheat
warning, seeEngine Overheating on page 5-27.
Parking on Hills
{CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
But if you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet for an automatic transmission, or
into gear for a manual transmission. Turn your
wheels into the curb if facing downhill or into traffic
if facing uphill.
2. Have someone place chocks under the
trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Release the regular brakes.
4-45
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
•Start your engine.
•Shift into a gear.
•Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store
the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. SeeScheduled Maintenance on
page 6-4for more information. Things that are especially
important in trailer operation are automatic transmission
fluid (don’t overfill), engine oil, axle lubricant, belt,
cooling system and brake system. Each of these is
covered in this manual. If you’re trailering, it’s a
good idea to review these sections before you start
your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
4-46
Trailer Wiring Harness
The trailer wiring is a four-wire harness assembly. The
wires are blunted and taped to the wiring harness.
The harness and wiring are stored under the vehicle on
the driver’s side. The harness has no connector and
should be wired by a qualified electrical technician. The
technician can use the following color code chart
when connecting the wiring harness to your trailer.
•Black: Ground wire.
•Yellow: Left turn lamps.
•Dark Green: Right turn lamps.
•Brown: Parking lamps.
Securely attach the harness to the trailer, then tape or
strap it to your vehicle’s frame rail. Be sure you
leave it loose enough so the wiring doesn’t bend or
break, but not so loose that it drags on the ground. Store
the harness in its original place. Wrap the harness
together and tie it neatly so it won’t be damaged.
Trailer Recommendations
You must subtract your hitch load from the Cargo
Weight Rating (CWR) for your vehicle. The CWR is the
maximum weight of the load your vehicle can carry.
The CWR does not include the weight of the people
inside, but you can figure about 150 lbs (68 kg) for each
seating position. The total cargo load must not be
more than the vehicle’s CWR. Make sure to weigh your
vehicle with your trailer attached, so that you won’t
go over the GVWR or the GAWR.
You’ll get the best performance if you spread out the
weight of your load the right way, and if you choose the
correct hitch and trailer brakes.
For more information, seeTowing a Trailer on page 4-35
earlier in this section.
