2003 GMC YUKON DENALI tow

Notice: If your wheels won’t turn, don’t try to drive.
This might happen
if you were stuck in very deep
sand or mud or were up against
a solid object. You
could damage your transmission. Also, if you
stop when going uphill, don’t hold your vehicle there
with only the accelerator pedal. This could overheat
and damage the transmission. Use your brakes
or shift into
PARK (P) to hold your vehicle in
position on
a hill.
On cold days, approximately
32°F (OOC) or colder, your
transmission is designed
to shift differently until the
engine reaches normal operating temperature. This is
intended
to improve heater performance.
Tow/HauI Mode
Your vehicle is equipped with a tow/haul mode. The
button is located on the end
of the column shift lever.
You can use this feature
to assist when towing or
hauling a heavy load. See “Tow/Haul Mode” under
Towing
a Trailer on page 4-47 for more information.
The tow/haul mode also interacts with the AutorideTM
feature
to enhance the ride when trailering or with
a loaded vehicle. See AutorideTM on page
4-46.

cause your rear brakes to overheat. You may have
to replace them, and you could also damage
other parts
of your vehicle.
If you are towing a trailer and are parking on any hill,
see Towing a Trailer on page
4-47.

vehicle can move suddenly. You or others
could be injured.

If you’re pulling a
trailer, see “Towing a Trailer’’ in the Index.
1. Hold the brake pedal down with your right foot and
set the parking brake.

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

Running Your Engine While You
Are Parked
It’s better not to park with the engine running. But if you
ever have
to, here are some things to know.
Id g the en- le with the climate co ,ol
system off could allow dangerous exhaust into
your vehicle. See the earlier Caution under
“Engine Exhaust.”
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even
if
the fan is at the highest setting. One place this
can happen is a garage. Exhaust
- with CO -
can come in easily. NEVER park in a garage
with
the engine running.
Another closed-in place can be a blizzard. See
“Winter Driving”
in the Index.
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with

3. Keep pressing the on/off button until the desired
zone number appears in the display. Release the
button. After approximately four seconds of
inactivity, the new zone number will be locked in
and the comphemp display will return.
4. Calibrate the compass as described below.
Compass Calibration
The compass may need calibration if one of the
following occurs:
After approximately five seconds, the display does
not show a compass heading
(N for North, for
example), there may be a strong magnetic field
interfering with the compass. Such interference may
be caused by a magnetic antenna mount, magnetic
note pad holder or a similar magnetic item.
The compass does not display the correct heading
and the compass zone variance is set correctly. In
order
to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed, push
the on/off button for approximately
12 seconds or
until CAL is displayed.
The compass can be calibrated by drivingthe vehicle in
circles at
5 mph (8 km/h) or less until the display
reads a direction.
Passenger Air Bag Indicator
Your vehicle may be equipped with a passenger air bag
indicator, on the mirror glass, just above the buttons.
If your vehicle has this feature, the mirror will display the
word
ON, or an air bag symbol in Canada, when the
passenger air bag is enabled. For more information, see
Passenger Sensing System on page
1-8 1.
Cleaning the Mirror
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner.
Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner
to enter the mirror housing.
