instrument cluster GMC YUKON 2007 Owner's Manual

{CAUTION:
Anyone who is up against, or very close
to, any airbag when it inates can be
seriously injured or killed. Airbags plus
lap-shoulder belts offer the best
protection for adults, but not for young
children and infants. Neither the vehicle’s
safety belt system nor its airbag system is
designed for them. Young children and
infants need the protection that a child
restraint system can provide. Always
secure children properly in your vehicle.
To read how, seeOlder Children on
page 61orInfants and Young Children on
page 64.
Occupants should not lean on or sleep
against the door in the rst or second row
seats, or the rear windows in the third row
seat, if your vehicle has roof-mounted
rollover airbags.There is an airbag
readiness light on the
instrument panel cluster,
which shows the
airbag symbol.
The system checks the airbag electrical system for
malfunctions. The light tells you if there is an
electrical problem. SeeAirbag Readiness Light on
page 229for more information.
92

{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
and stays on, it means that something
may be wrong with the airbag 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 airbag. See
Airbag Readiness Light on page 229for
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. See
Adding Equipment to Your Airbag-Equipped
Vehicle on page 107for more information about
modications that can affect how the system
operates.
{CAUTION:
Stowing of articles under the passenger’s
seat or between the passenger’s seat
cushion and seatback may interfere with
the proper operation of the passenger
sensing system.

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 do
not, 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 will be parking your
vehicle. The dealer can give you the best
advice for that particular area.Automatic Transmission Operation
Your vehicle has an Hydra-Matic®6L80
automatic transmission, and has an electronic
shift position indicator within the instrument panel
cluster. The electronic shift position indicator
displays when the shift lever is moved out
of PARK (P).
There are several different positions for the
shift lever.
See “Driver Shift Control (DSC)” later in this
section.
145

When in the MANUAL MODE (M) a number will
display next to the M, indicating the current gear
that has been selected. The number displayed in
the gear indicator is the highest gear that can be
used. However, your vehicle can automatically shift
to lower gears as it adjusts to driving conditions.
This means that all gears below that number are
available. When FIFTH (5) is selected, FIRST (1)
through FIFTH (5) gears are automatically shifted
by the vehicle, but SIXTH (6) cannot be used until
the plus/minus button located on the steering
column lever is used to change to the gear.
The DSC controls the vehicle and engine speed
while driving down a hill or towing a trailer, by
allowing you to select a desired range of gears.
The transmission will prevent a gear range until a
speed that is appropriate for current driving
conditions is achieved. If shifting is prevented for
any reason, the currently selected gear will
ash multiple times in the instrument panel cluster.
Grade Braking is not available when the Driver
Shift Control is active. SeeTow/Haul Mode
on page 150for more information.
While using the DSC, Cruise Control and the
Tow/Haul mode can be used.Tow/Haul Mode
Your vehicle has a tow/haul mode. The tow/haul
mode adjusts the transmission shift pattern to
reduce shift cycling, providing increased
performance, vehicle control, and transmission
cooling when towing or hauling heavy loads.
150

Press the button located on the end of the shift
lever to turn the tow/haul on or off. When the
tow/haul is on, a light on the instrument panel
cluster will come on.
SeeTow/Haul Mode Light on page 242for more
information.
Also see “Tow Haul Mode” underTowing a Trailer
on page 400for more information.
The tow/haul mode works with the Autoride
®
feature, if the vehicle has this, to enhance the ride
when trailering or with a loaded vehicle. See
Autoride
®on page 399.
Grade Braking
Grade Braking assists when driving on a downhill
grade. It maintains the vehicle’s speed by
automatically implementing a shift schedule that
uses the engine and the transmission to slow
the vehicle. This reduces wear on the brakes
system and increases control of the vehicle. The
system constantly monitors the vehicle’s speed,
acceleration, throttle position, and whether
the brake pedal is being pressed, and determines
when to keep the current vehicle speed or to
slow down. The system will then automatically
command downshifts that reduces the vehicles
speed, until the brake pedal is no longer
being pressed. This indicates the desired vehicle
speed has been reached.
The tow/haul mode and grade braking shift
modes can be activated by pressing the button on
the end of the shift control stalk. While in the
DSC mode, grade braking is deactivated, allowing
the driver to select a gear.
SeeAutomatic Transmission Operation on
page 145for more information.

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 is nished, the lever will
return automatically.To signal a lane change, raise or lower the lever for
less than one second until the arrow starts to ash.
This will cause the turn signals to automatically
ash three times. It will ash six times if tow-haul
mode is active. Holding the turn signal lever for
more than one second will cause the turn signals
to ash until you release the lever. The lever will
return by itself when it is released.
An arrow on the
instrument panel cluster
will ash in the
direction of the turn or
lane change.
As you signal a turn or a lane change, if the
arrows ash more quickly than normal, a signal
bulb may be burned out and other drivers will not
see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when
you signal a turn, check for burned-out bulbs and a
blown fuse. SeeFuses and Circuit Breakers on
page 538.
194

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
each ash of the turn signal and the message
TURN SIGNAL ON will also appear in the DIC.
To turn the chime and message off, move the
turn signal lever to the off position.
Headlamp High/Low-Beam Changer
53(Headlamp High/Low Beam
Changer):To change the headlamps from low to
high beam, 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 indicator
light on the instrument
panel cluster will also
be on.
Flash-to-Pass
This feature lets you 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 in the automatic position.
To use it, pull the turn signal lever toward you,
then release it.
If your headlamps are in the automatic position or
on low beam, your high-beam headlamps will
turn on. They will stay on as long as you hold the
lever toward you. The high-beam indicator on
the instrument panel cluster will come on. Release
the lever to return to normal operation.
