key GMC YUKON DENALI 2003 Owner's Manual

Move the lever up as far as it will go.
3. Turn the ignition key to LOCK.
4. Remove the key and take it with you.
If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in PARK (P).
Leaving Your Vehicle With the Engine
Running
I
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move suddenly
if the shift lever is not fully in
PARK (P) with the parking brake firmly set.
And,
if you leave the vehicle with the engine
running,
it could overheat and even catch fire.
You or others could be injured. Don’t leave
your vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and the
parking brake is firmly set before you leave it. After you
move the shift lever into PARK (P): hold the regular
brake pedal down. Then, see
if you can move the shift
lever away from PARK (P) without first pulling it
toward you. If you can, it means that the shift lever
wasn’t fully locked into PARK
(P).

Torque Lock
If you are parking on a hill and you don’t shift your
vehicle into PARK (P) properly, the weight of the vehicle
may put
too much force on the parking pawl in the
transmission. You may find it difficult
to pull the shift
lever
out of PARK (P). This is called torque lock.
To prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the
driver’s seat. To find
out how, see Shifting lnto Park (P)
on page 2-26.
When you are ready to drive, move the shift lever out of
PARK (P) before you release the parking brake.
If torque lock does occur, you may need
to have another
vehicle push yours a little uphill
to take some of the
pressure from the parking pawl in the transmission,
so
you can pull the shift lever out of PARK (P).
Shifting Out of Park (P)
Your vehicle has an automatic transmission shift lock
control system. You have
to fully apply your regular
brakes before you can shift from PARK (P) when the
ignition is in RUN. See Automatic Transmission
Operation
on page 2-22.
If you cannot shift out of PARK (P), ease pressure on
the shift lever and push the shift lever all the way up into
PARK (P) as you maintain brake application. Then,
move the shift lever into the gear you want.
If you ever hold the brake pedal down but still can’t shift
out of PARK (P), try this:
1. Turn the key to LOCK.
2. Apply and hold the brake until the end of Step 4.
3. Shift the vehicle to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear
you want.
5. Have the system fixed as soon as you can.

Automatic Headlamp System
When it is dark enough outside and the headlamp
switch is in AUTO, your automatic headlamp system will
turn on your headlamps at the normal brightness
along with other lamps such as the taillamps,
sidemarker, parking lamps, roof marker lamps and the
instrument panel lights. The radio lights will also be dim.
To turn off the automatic headlamp system, turn the
exterior lamps switch
to the off position and then
release.
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 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. 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. See ”Instrument
Panel Brightness” under lnterior
Lamps on page 3-76.
Lamps On Reminder
If a door is open, a reminder chime will sound when
your 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 or AUTO and
then back on. In the automatic mode, the headlamps
turn off once the ignition is in LOCK and the headlamps
on at exit delay ends
(if enabled in the DIC).
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.
3-1 4

The DRL system will come on when the following
conditions are met:
0 The ignition is on,
the exterior lamps control is in AUTO,
the transmission is not in PARK (P), and
0 the light sensor determines it is daytime.
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.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
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.
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
your instrument panel.
Press the button
to turn the fog lamps on while the
headlamps or parking lamps 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 the 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.
3-1 5

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.
