key GMC ACADIA 2007 Service Manual

Passenger Safety Belt
Reminder Light
Several seconds after the key is turned to ON or
START, a chime will sound for several seconds
to remind the front passenger to buckle their
safety belt. This would only occur if the passenger
airbag is enabled. SeePassenger Sensing
System on page 85for more information. The
passenger safety belt light will also come on
and stay on for several seconds, then it will ash
for several more.
This chime and light
are repeated if the
passenger remains
unbuckled and
the vehicle is
in motion.
If the passenger’s safety belt is buckled,
neither the chime nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the
instrument panel cluster, which shows the
airbag symbol. The system checks the airbag’s
electrical system for malfunctions. The light
tells you if there is an electrical problem.
The system check includes the airbag sensor,
the pretensioners, the airbag modules, the wiring
and the crash sensing and diagnostic module.
For more information on the airbag system,
seeAirbag System on page 76.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should
go out. This means
the system is ready.

If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.
{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays
on after you start your vehicle.
The airbag readiness light should ash for a
few seconds when you turn the ignition key to ON.
If the light does not come on then, have it xed
so it will be ready to warn you if there is a problem.
Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system.
Your instrument panel has a passenger airbag
status indicator.
When you start the vehicle, the passenger airbag
status indicator will light ON and OFF, or the
symbol for on and off, for several seconds as a
system check. If you use remote start to start your
vehicle from a distance, if your vehicle has this
feature, you may not see the system check. Then,
after several more seconds, the status indicator
will light either ON or OFF, or either the on
or off symbol to let you know the status of the
right front passenger’s frontal and seat-mounted
side impact airbags.

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the other
part can still work and stop you. For good braking,
though, you need both parts working well.
If the warning light comes on, there is a brake
problem. Have your brake system inspected
right away.
This light should come on briey when you turn
the ignition key to ON. If it does not come on then,
have it xed so it will be ready to warn you if
there is a problem.
This light may also come on due to low brake uid.
SeeBrakes on page 421for more information.When the ignition is on, the brake system warning
light will also come on when you set your parking
brake. The light will stay on if your parking brake
does not release fully. If it stays on after your
parking brake is fully released, it means you have
a brake problem.
If the light comes on while you are driving, pull off
the road and stop carefully. Make sure the parking
brake is fully released. You may notice that the
pedal is harder to push or, the pedal may go closer
to the oor. It may take longer to stop. If the light
is still on, have the vehicle towed for service.
SeeTowing Your Vehicle on page 367.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.United StatesCanada

Anti-Lock Brake System
Warning Light
Your vehicle has the Anti-Lock Brake System (ABS).
This light will come on
when your engine is
started and may stay
on for several seconds.
This is normal.
If the light stays on, turn the ignition to off.
If the light comes on and the chime sounds
when you are driving, pull your vehicle over to a
safe location and stop as soon as possible.Turn the ignition off. Then start the engine again
to reset the system. If the light still stays on,
or comes on again while you are driving, your
vehicle needs service. If the regular brake
system warning light is not on, you still have
brakes, but you do not have anti-lock brakes.
If the regular brake system warning light is also
on, you do not have anti-lock brakes and there
is a problem with your regular brakes. SeeBrake
System Warning Light on page 222earlier in
this section.
The ABS warning light will come on briey when
you turn the ignition key to ON. This is normal.
If the light does not come on then, have it xed so
it will be ready to warn you if there is a problem.
223

This light should come on, as a check to show
you it is working, when the ignition is on and the
engine is not running. If the light does not
come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and could damage the emission
control system on your vehicle. Diagnosis and
service might be required.
Light On Steady— An emission control
system malfunction has been detected on
your vehicle. Diagnosis and service might be
required.
If the Light is Flashing
The following can prevent more serious damage
to your vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If you are towing a trailer, reduce the
amount of cargo being hauled as soon
as it is possible.If the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to
do so, stop the vehicle. Find a safe place to
park the vehicle. Turn the key off, wait at least
10 seconds, and restart the engine. If the
light remains on steady, see “If the Light Is On
Steady” following. If the light is still ashing, follow
the previous steps and see your dealer/retailer
for service as soon as possible.
If the Light Is On Steady
You might be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 390.
The diagnostic system can determine if the
fuel cap has been left off or improperly installed.
A loose or missing fuel cap allows fuel to
evaporate into the atmosphere. A few driving
trips with the cap properly installed should
turn the light off.

Oil Pressure Light

engine oil pressure.The light comes on when you turn your key to ON
or START. It goes off once you start your engine.
That is a check to be sure the light works. If it does
not come on, be sure to have it xed so it will be
there to warn you if something goes wrong.
When the light comes on and stays on, it means
that oil is not owing through your engine properly.
You could be low on oil and you might have
