2003 - Yukon/Yukon XL

Ignition Positions
With the key in the ignition switch, you can turn the key
to four different positions.
A (LOCK):This position locks your ignition and
transmission. It’s a theft-deterrent feature. You will only
be able to remove your key when the ignition is
turned to LOCK.
B (ACCESSORY):This position lets you use things like
the radio, power windows and the windshield wipers
when the engine is off.Notice:If your key seems stuck in LOCK and you
can’t turn it, be sure you are using the correct key;
if so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break the
key or the ignition switch. If none of these works,
then your vehicle needs service.
C (RUN):This is the position for driving.
D (START):This position starts your engine.
Retained Accessory Power (RAP)
Your vehicle may be equipped with a Retained
Accessory Power (RAP) feature which will allow certain
features on your vehicle to continue to work up to
10 minutes after the ignition key is turned to OFF.
Your radio, power windows, sunroof (if equipped), and
OnStar
®System (if equipped) will work when the ignition
key is in RUN or ACCESSORY. Once the key is
turned from RUN to LOCK, these features will continue
to work for up to 10 minutes or until a door is opened.

Cargo Cover
Cargo Tie Downs
Your vehicle may be
equipped with cargo tie
downs in the rear
cargo area that allow you
to strap cargo in and
keep it from moving inside
the vehicle.
When not using the tie downs,ip them down out of
the way.
Sunroof
Your vehicle may be equipped with a power sliding
sunroof. To open or close your sunroof, the ignition or
RAP needs to be active. See″Retained Accessory
Power″under Starting and Operating Your Vehicle.
Press and release the rear side of the button located in
the front overhead console to express-open the glass
panel and sunshade. To close the glass panel,
press and hold the front of the button. The glass will not
be fully seated unless the button is held until the
glass stops moving. With the sunroof closed, press the
forward side of the button to open the sunroof to the
vent position.
The sunroof is also equipped with a sunshade which
you can pull forward to block sun rays. The sunshade
will not close when the sunroof is open.

2003 - Yukon/Yukon XL

If a hand, arm, or other object is blocking the sunroof
glass panel as it is closing, the glass panel will stop
at the obstruction. After the obstruction is removed, the
glass panel can be closed or opened.
Use care not to leave the sunroof open for long periods
of time as debris may collect in the tracts.
If the battery has been recharged, disconnected or is
not working, you may need to reprogram the sunroof. To
do this, start the vehicle and press the forward side of
the sunroof switch until the glass panel moves to a fully
closed position. Release, and press again to move to
the vent position which occurs when the sunroof is fully
tilted rearward. This will reset the memory and enable
the sunroof to function properly.Vehicle Personalization
Memory Seat
If your vehicle has this
feature, then the controls
for the memory function
are located on the
driver’s door.
These buttons are used to program and recall memory
settings for the driver’s seat, throttle and brake
pedals, both the driver’s and passenger’s outside mirror,
and the radio station presets. The settings for these
features can be personalized for both driver 1 and driver
2. Driver 1 or driver 2 corresponds to the memory
buttons labeled 1and 2 on the driver’s door.

XM™Satellite Radio Antenna
System (United States Only)
Your XM™Satellite Radio antenna is located on the
roof of your vehicle. Keep this antenna clear of
snow and ice build up for clear radio reception.
The performance of your XM™system may be affected
if your sunroof is open.
Loading items onto the roof of your vehicle can interfere
with the performance of your XM™system. Make
sure that the XM™satellite antenna is not obstructed.
Chime Level Adjustment
The radio is the vehicle chime producer. To change the
volume level, press and hold pushbutton 6 with the
ignition on and the radio power off. The chime volume
level will change from the normal level to loud, and LOUD
will be displayed on the radio. To change back to the
default or normal setting, press and hold pushbutton 6
again. The chime level will change from the loud level to
normal, and NORMAL will be displayed. Each time the
chime volume is changed, three chimes will sound as an
example of the new volume selected. Removing the radio
and not replacing it with a factory radio or chime module
will disable vehicle chimes.
