2008 GMC ENVOY instrument cluster

{CAUTION:
Airbags inate with great force, faster than
the blink of an eye. Anyone who is up against,
or very close to, any airbag when it inates
can be seriously injured or killed. Do not sit
unnecessarily close to the airbag, as you would
be if you were sitting on the edge of your seat or
leaning forward. Safety belts help keep you in
position before and during a crash. Always wear
your safety belt, even with airbags. The driver
should sit as far back as possible while still
maintaining control of the vehicle.
Occupants should not lean on or sleep against
the door or side windows in seating positions
with roof-rail airbags.
{CAUTION:
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, see
Older Children on page 1-32orInfants and
Young Children on page 1-35.
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 3-33
for more information.
1-55

{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 airbag(s). SeeAirbag Readiness Light
on page 3-33for more on this, including
important safety information.A thick layer of additional material, such as a blanket or
cushion, or aftermarket equipment such as seat covers,
seat heaters, and seat massagers can affect how well
the passenger sensing system operates. We recommend
that you not use seat covers or other aftermarket
equipment other than any that GM has approved for
your specic vehicle. SeeAdding Equipment to Your
Airbag-Equipped Vehicle on page 1-66for 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.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Content Theft-Deterrent
Your vehicle may have a content theft-deterrent alarm
system.
The security light is
located on the instrument
panel cluster.To operate the system:
1. Open the door.
2. Lock the door with the power door lock switch
or the Remote Keyless Entry (RKE) transmitter.
The security light should ash.
The system will not activate if the doors are locked
with the key or manual door lock.
3. Close all doors. The security light should turn off
after about 30 seconds. The alarm is not armed
until the security light turns off.
If a locked door is opened without the key or the RKE
transmitter, the alarm will go off. The headlamps
and parking lamps will ash for two minutes, and the
horn will sound for 30 seconds, then will turn off to save
the battery power.
To avoid setting off the alarm by accident:
Always lock the vehicle using the door keyafterthe
doors are closed.
Always unlock a door with a key, or use the RKE
transmitter. Unlocking a door any other way will
set off the alarm.
To turn off the alarm, press unlock on the RKE
transmitter or unlock any door with the key.

AUTO (Automatic Four-Wheel Drive):This setting is
ideal for use when road conditions are variable. When
driving your vehicle in automatic four-wheel drive, the
front axle is engaged, but the vehicle’s power is sent 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 Two-Wheel High.
4
m(Four-Wheel High):This setting should be used
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.
4
n(Four-Wheel Low):This setting also engages
your front axle and delivers extra torque. It sends
maximum power to all four wheels. You might choose
this setting if you are driving off-road in deep sand,
deep mud, 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. SeeParking Brake on
page 2-33.
NEUTRAL:Shift the vehicle’s transfer case
to NEUTRAL only when towing your vehicle.
SeeRecreational Vehicle Towing on page 4-40
for more information.
An indicator light in the knob will show you which
position the transfer case is in. The indicator lights will
come on briey when you turn on the ignition and one will
stay on. If the lights do not come on, you should take your
vehicle to your dealer for service. An indicator light will
ash while shifting the transfer case. It will stay on when
the shift is complete. If for some reason the transfer case
cannot make a requested shift, it will return to the last
chosen setting.
If the service Four-Wheel Drive Warning Light on the
instrument panel cluster stays on, you should take
your vehicle to your dealer for service. SeeService
Four-Wheel Drive Warning Light on page 3-47for
further information.

Parking Brake
To set the parking brake,
hold the regular brake
pedal down with your
foot and pull up on
the parking brake lever
located between the seats.
To release the parking brake, hold the regular brake
pedal down. Pull the parking brake lever up until you
can press in the button at the end of the lever. Hold the
button in as you move the parking brake lever all the
way down.If the ignition is on, the brake system warning light on
the instrument panel cluster will come on. SeeBrake
System Warning Light on page 3-38.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and you must park on a hill,
seeTowing a Trailer on page 4-45.

Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
GTurn and Lane Change Signals
23Headlamp High/Low-Beam Changer
Flash-to-Pass Feature
NWindshield Wipers
JWindshield Washer
ICruise Control
Turn and Lane-Change Signals
The turn signal has two upward and two downward
positions.
To signal a turn, move the lever all the way up or down.
When the turn is nished, the lever returns automatically.
An arrow on the instrument
panel cluster ashes in the
direction of the turn or
lane change.
To signal a lane change, raise or lower the lever until
the arrow starts to ash. Hold it there until your lane
change is completed. The lever returns by itself when
released.
If the arrows ash more quickly than normal, a signal
bulb could be burned out. Replace the bulb. If the arrows
do not go on at all when you signal a turn, check the
fuse. SeeFuses and Circuit Breakers on page 5-110
and check for burned-out bulbs.
If you have a trailer towing option with added wiring for
the trailer lamps, a turn signal asher is used. With this
asher installed, the signal indicator ashes even if a turn
signal bulb is burned out. Check the front and rear turn
signal lamps regularly to make sure they are working.
