2008 GMC ACADIA warning

Ignition Positions
With the key in the ignition,
you can turn it to four
different positions.
In order to shift out of PARK (P), ignition must be in
ON/RUN or ACC/ACCESSORY and the regular brake
pedal must be applied.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the key.
Use the correct key and turn the key only with your
hand. Make sure the key is all the way in. If none of
this works, then your vehicle needs service.
A (LOCK/OFF):This is the only position in which you
can remove the key. This position locks the ignition and
transmission. If the steering wheel is locked, move it from
right to left and turn the key to ACC/ACCESSORY. If
none of this works, then your vehicle needs service.B (ACC/ACCESSORY):This position allows you to use
things like the radio and the windshield wipers while
the engine is off. This position will also allow you to turn
off the engine.
C (ON/RUN):This is the position that the switch returns
to after you start your engine and release the key.
The switch stays in ON/RUN when the engine is
running. But even when the engine is not running, you
can use ON/RUN to operate your electrical power
accessories, and to display some instrument panel
warning lights.
The battery could be drained if you leave the key in the
ACC/ACCESSORY or ON/RUN position with the
engine off. You may not be able to start your vehicle if
the battery is allowed to drain for an extended period
of time.
D (START):This position starts the engine. When the
engine starts, release the key. The ignition switch
will return to ON/RUN for normal driving.

push down the parking
brake pedal down
with your left foot.
If the ignition is on, the brake system warning light will
come on. SeeBrake System Warning Light on
page 3-47.Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the brake
warning light is off before driving.
To release the parking brake, hold the regular brake
pedal down with your right foot. Push down momentarily
on the parking brake pedal with your left foot until you
feel the pedal release, then slowly pull your foot up
off the park brake pedal. If the parking brake is
not released when you begin to drive, the brake system
warning light will be on and a chime will sound
warning you that the parking brake is still on.

The delay between wiping cycles becomes shorter
as the band is moved to the top of the lever. This can

Heated Windshield Washer
If your vehicle has the heated windshield washer uid
system it can be used to help clear ice, snow, tree sap,
or bugs from the windshield. This feature only works
with the front wiper system.
The button is located

the heated windshield washer uid system. This
activation begins four heated wash/wipe cycles.
The rst heated wash/wipe cycle can take up to
40 seconds to occur, depending on outside temperature.
After the rst wash/wipe cycle, it can take up to
20 seconds for each of the remaining cycles. Press
the button again to turn off the heated windshield
washer uid system or it will automatically turn off
after four wipe cycles have been completed.When the heated windshield washer uid system is
activated under certain outside temperature conditions,
steam might ow out of the washer nozzles for a short
period of time before washer uid is sprayed. This is a
normal condition.
WASHER FLUID LOW ADD FLUID is displayed on the

wiper on and off. The wiper speed cannot be changed.
Y(Wash):Press this symbol to spray washer uid on
the rear window. The window wiper will also come on.
Release the button when enough uid has been sprayed
on the window. The rear wiper will run a few more cycles
after it is released. If the rear wiper function was already
on, prior to pressing the wash button, it will stay on until
the wiper button is pressed again.
The rear window washer uses the same uid that is in
the windshield washer reservoir. SeeWindshield Washer
Fluid on page 5-34.
