instrument cluster GMC YUKON 2003 Owner's Manual

There is an air bag
readiness light on the
instrument panel cluster,
which shows the air
bag symbol.
The system checks the air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. SeeAir Bag Readiness Light on page 3-40
for more information.Where Are the Air Bags?
The driver’s frontal air bag is in the middle of the
steering wheel.

If a person of adult-size is sitting in the right front
passenger’s seat, but the off indicator is lit, it could be
because that person isn’t sitting properly in the seat. If
this happens, turn the vehicle off and ask the person to
place the seatback in the full upright position, then sit
upright in the seat, centered on the seat cushion, with the
person’s legs comfortably extended. Restart the vehicle
and have the person remain in this position for about two
minutes. This will allow the system to detect that person
and then enable the passenger’s air bag.
{CAUTION:
If the air bag readiness light in the instrument
panel cluster ever comes on and stays on, it
means that something may be wrong with the
air bag system. If this ever happens, have the
vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger’s seat may not have the protection
of the frontal air bag. See“Air Bag Readiness
Light”in the Index for more on this, including
important safety information.
Aftermarket equipment, such as seat covers, can affect
how well the passenger sensing system operates.
You may want to consider not using seat covers or other
aftermarket equipment if your vehicle has the passenger
sensing system.

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is located on the driver’s side of the engine
compartment, near the power steeringuid
reservoir. If you have a diesel engine, refer to
diesel supplement for location.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause afire. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord
won’t reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you don’t, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.Automatic Transmission Operation
There are several different positions for your shift lever.
Your vehicle is equipped with an automatic transmission
and features an electronic shift position indicator
within the instrument panel cluster. This display must be
powered anytime the shift lever is capable of being
moved out of PARK (P).
PARK (P):This position locks your rear wheels. It’s the
best position to use when you start your engine
because your vehicle can’t move easily.

The transfer case buttons are located to the left of the
instrument panel cluster.
Use these switches to shift into and out of four-wheel
drive.You can choose among four driving settings:
h(2HI):This setting is used for driving in most street
and highway situations. Your front axle is not engaged
in two-wheel drive. This setting also provides the
best fuel economy.
AUTO 4WD:This setting is ideal for use when road
conditions are variable. When driving your vehicle
in AUTO 4WD, the front axle is engaged, but the
vehicle’s power is sent only to the rear wheels. When
the vehicle senses a loss of traction, the system
will automatically engage four-wheel drive. Driving in
this mode results in slightly lower fuel economy
than 2HI.
G(4HI):Use the 4HI position when you need extra
traction, such as on snowy or icy roads or in most
off-road situations. This setting also engages your front
axle to help drive your vehicle. This is the best setting
to use when plowing snow.

2003 - Yukon/Yukon XL

All-Wheel Drive with Stabilitrak®
With this feature, engine power is sent to all four wheels
all the time.
This is like four-wheel drive, but there is no separate
lever or switch to engage or disengage the front axle. It
is fully automatic, and adjust itself as needed for
road conditions.
The transfer case buttons are located to the left of the
instrument panel cluster.
Use these switches to shift into and out of four-wheel
drive.You can choose among three driving settings:d(Stabilitrak®):This button is used with the
Stabilitrak®system and is also used to shift the transfer
case into Neutral. For more information on using
Stabilitrak
®seeStabilitrak®System on page 4-12.
f(All-Wheel Drive):This setting delivers power to
all four wheels as needed depending on road and driving
conditions.
g(4LO):This setting delivers extra torque. You may
never need this setting. It sends maximum power to
all four wheels. You might choose 4LO if you are driving
off-road in deep sand, deep mud, deep snow and
climbing or descending steep hills.
{CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the
transmission is in PARK (P). You or someone
else could be seriously injured. Be sure to set
the parking brake before placing the transfer
case in NEUTRAL. See″Parking Brake″in the
Index.

Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
•GTurn and Lane Change Signals
•3Headlamp High/Low Beam Changer
•Flash-to-Pass Feature
•NWindshield Wipers
•LWindshield Washer
•JCruise Control (If Equipped)
For information on the exterior lamps, seeExterior

Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn isfinished, the lever will return
automatically.
An arrow on the instrument panel cluster willflash in the
direction of the turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts toflash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
If you move the lever all the way up or down, and the
arrowflashes at twice the normal rate, a signal bulb may
be burned out and other drivers may not see your
turn signal.
3-8
2003 - Yukon/Yukon XL

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 for burned-out bulbs and a blown fuse.
SeeFuses and Circuit Breakers on page 5-98.
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 eachflash 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 to high beam
or push the lever toward the instrument panel. To return
to low-beam headlamps, pull the multifunction lever
toward you. Then release it.
When the high beams are
on, this light on the
instrument panel cluster
also will be on.
Flash-To-Pass
This feature allows you to 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 off.
To use it, pull the turn signal lever toward you.
If your headlamps are off 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 turn the high-beam
headlamps off.
Windshield Wipers
8
: Mist
9:Off
You control the windshield wipers by turning the band
with the wiper symbol on it.
For a single wiping cycle, turn the band to mist. Hold it
there until the wipers start, then let go. The wipers
will stop after one wipe. If you want more wipes, hold
the band on mist longer.
You can set the wiper speed for a long or short delay
between wipes. This can be very useful in light rain
or snow. Turn the band to choose the delay time. The
closer to the top of the lever, the shorter the delay.

2003 - Yukon/Yukon XL

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 bright enough 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 Control”underInterior
Lamps on page 3-18.
To idle your vehicle with the automatic headlamp
system off, turn the control to the off position.
You may be able to turn off your Automatic Headlamp
System. See″Daytime Running Lamps (DRL)″later
in this section for more information.
Your headlamps will also stay on after you exit the
vehicle. You can program this feature using the Driver
Information Center. SeeDriver Information Center (DIC)
on page 3-53.
As with any vehicle, you should turn on the regular
headlamp system when you need them.Lamps On Reminder
A reminder chime will sound when your headlamps or
parking lamps are manually turned on and your
ignition is off, in LOCK, ACCESSORY, or your door is
open. To disable the chime, turn the light off then
back on.
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 following
conditions are met:
•the ignition is on,
•the exterior lamps control is AUTO,
•the automatic transmission is not in PARK (P),
•the light sensor determines it is daytime and
When the DRL are on, only your DRL lamps will be on.
The taillamps, sidemarker and other lamps won’tbe
on. The instrument panel won’t be lit up either.
