2002 GMC YUKON DENALI instrument panel

2-39 Puddle Lamps
Your vehicle is equipped with puddle lamps to help you
see the area near the base of the front doors when it is
dark out. The puddle lamps will illuminate when a door
is opened or when you press the UNLOCK button on the
keyless entry transmitter. The lamps will time out or
turn off once the engine is started.
You can program the puddle lamps not to come on if
you choose. See ªSecondary Information Centerº in the
Index for more information.
Daytime Running Lamps
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 come on when:

The ignition is on,

the exterior lamps control is off,

the automatic transmission is not in PARK (P),

the light sensor determines it is daytime and

the parking brake is released.
When the DRL are on, only your DRL lamps 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 automatic headlamp
system will switch from DRL to the headlamps or the
last chosen headlamp setting that was used.
When you turn the exterior lamps control to the off
position, the headlamps will go off, and your DRL
lamps will illuminate, provided it is not dark outside.
To idle your vehicle with the DRL off, set the parking
brake. Shifting the transmission into PARK (P) will also
allow you to idle the vehicle with the DRL off. The
DRL will stay off until you release the parking brake
or shift the transmission out of PARK (P).

This procedure applies only to vehicles first sold in the
United States.
When necessary, you may turn off the automatic
headlamp system and the Daytime Running Lamps
(DRL) feature by following these steps:
1. Turn the ignition to RUN.
2. Press the DOME OVERRIDE button four times
within six seconds. After the fourth press of the
button, a chime will sound informing you the system
is off.
3. The system will revert back to the automatic mode
when the DOME OVERRIDE button is again pushed
four times within six seconds (a chime will sound),
or when the ignition is turned off and on again.
When the system is turned off, the headlamps will not
automatically come on when it becomes dark outside.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Fog Lamps
Use the fog lamps for better vision in foggy or misty
conditions. Your parking lamps and/or low
-beam
headlamps must be on for your fog lamps to work.
The fog lamp button is
located on the left side of
the instrument panel.
Press the button to turn the fog lamps on while the
headlamps are on. Press the button again to turn them
off. An indicator light will glow near the button when
the fog lamps are on.
Remember, fog lamps alone will not give off as much
light as your headlamps. Never use your fog lamps in
the dark without turning on your headlamps.
The fog lamps will go off whenever your high
-beam
headlamps come on. When the high beams go off, the
fog lamps will come on again.
The fog lamps will be cancelled after the ignition is
turned off. If you still want to use the fog lamps after
you restart the vehicle, you will need to press the fog
lamp button again.

When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual's advice.
Waiting to do repairs can be costly
-- and even
dangerous. So please get to know your warning lights
and gages. They're a big help.
Your vehicle also has a message center that works along
with warning lights and gages. See ªMessage Centerº in
the Index.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about six seconds to remind people to
fasten their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light will
also come on and stay on
for about 20 seconds,
then it will flash for
about 55 seconds.
If the driver's belt is already buckled, neither the chime

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag's electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the air bag sensors, the air
bag modules, the wiring and the crash sensing and
diagnostic module. For more information on the air bag
system, see ªAir Bagº in the Index.
This light will come on
when you start your vehicle,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
