2001 GMC ENVOY instrument panel

2-48
As you signal a turn or a lane change, if the arrows flash
more quickly than normal, a signal bulb may be burned
out and other drivers won't see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you
signal a turn, check the fuse (see ªFuses and Circuit
Breakersº in the Index) and for burned
-out bulbs.
If you have a trailer towing option with added wiring for
the trailer lamps, a different turn signal flasher is used.
With this flasher installed, the signal indicator will flash
even if a turn signal bulb is burned out. Check the front
and rear turn signal lamps regularly to make sure they
are working.
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each flash of the turn
signal. To turn off the chime, move the turn signal lever
to the off position.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high or
high to low, pull the multifunction lever all the way
toward you. Then release it.
When the high beams
are on, this indicator light
on the instrument panel
cluster will also be on.
Flash-to-Pass
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass. It works
even if your headlamps are in the automatic position.
To use it, pull the turn signal lever toward you, but not
so far that you hear a click.
If your headlamps are in the automatic position or on
low beam, your high
-beam headlamps will turn on.
They'll stay on as long as you hold the lever toward you
and the high
-beam indicator on the instrument panel
cluster will come on. Release the lever to return to
normal operation.

Rear Window Washer/Wiper
This switch is located on
the instrument panel to the
right of the steering wheel.
To turn the rear wiper on, slide the switch to either
LO or HI. For delayed wiping, slide the switch to LO.
For steady wiping, slide the switch to HI. To turn the

The rear window washer uses the same fluid bottle
as the windshield washer. However, the rear window
washer will run out of fluid before the windshield
washer. If you can wash your windshield but not
your rear window, check your fluid level.
Cruise Control (If Equipped)
With cruise control, you can
maintain a speed of about
25 mph (40 km/h) or more
without keeping your foot
on the accelerator. This can
really help on long trips.
Cruise control does not
work at speeds below
about 25 mph (40 km/h).
If you have an automatic transmission and you apply
your brakes, the cruise control will shut off.
If you have a manual transmission and you apply
your brakes or push the clutch pedal, the cruise control
will shut off.

Exterior Lamps
The parking lamp and headlamp knob is on the driver's
side of the instrument panel.
Turn the knob clockwise to the parking lamps symbol to
manually turn on the following:

Parking Lamps

Sidemarker Lamps

Taillamps

License Plate Lamps

Instrument Panel LightsTurn the knob clockwise to the master lamps symbol

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. The radio lights will also be dim.
Your vehicle is equipped with a light sensor on the top
of the instrument panel under the radio speaker grill.
Be sure it is not covered or the system will be on
whenever the ignition is on.
The system may also turn on your 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 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.

system off, set the parking brake while the ignition is

driving conditions, but they can be especially helpful
in the short periods after dawn and before sunset.
Fully functional daytime running lights 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:

The ignition is on,

the headlamp switch is in automatic headlamp mode,

the sensor detects daytime light,

an automatic transmission is not in PARK (P), and

the parking brake is released.
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.

temporarily while the turn signals are activated.

Accessory Power Outlets
With the accessory power outlets, you can plug in
auxiliary electrical equipment. The accessory power
outlets are located near the center of the vehicle on the
lower part of the instrument panel. Just remove the
plug from the outlet and follow the proper installation
instructions that are included with any electrical
equipment you install. Some vehicles will have a small cover which must be
pulled down to access the accessory power outlets.
These vehicles will also have another power outlet
located in the lower rear of the center console.
Certain accessory power plugs may not be compatible
to the accessory power outlets and could result in blown
vehicle adapter fuses. If you experience a problem see
your dealer for additional information on accessory
power plugs.
These circuits are protected by a fuse and have
maximum current levels.
NOTICE:
Adding some electrical equipment to your vehicle
can damage it or keep other things from working
as they should. This wouldn't be covered by your
warranty. Check with your dealer before adding
anything that exceeds the fuse rating.
