bag, laptop, or other electronic
device. To turn off the warning light
and/or chime, remove the object
from the seat or buckle the
safety belt.
Airbag Readiness Light
This light shows 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 3‑26.
The airbag readiness light comes on
and stays on for several seconds
when the vehicle is started. Then
the light goes out.
{WARNING
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in
the vehicle might not inflate in a
crash, or they could even inflate
without a crash. To help avoid
injury, have the vehicle serviced
right away.
Passenger Airbag Status
Indicator
The vehicle has a passenger
sensing system. See Passenger
Sensing System on page 3‑33 for
important safety information. The
overhead console has a passenger
airbag status indicator.
United States
Canada and Mexico
When the vehicle is started, 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 are using
remote start, if equipped, to start
the vehicle from a distance, 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 frontal
airbag.
If the word ON or the on symbol is
lit on the passenger airbag status
indicator, it means that the right
front passenger frontal airbag is
enabled (may inflate).
If the word OFF or the off symbol
is lit on the passenger airbag
status indicator, it means that the
passenger sensing system has
turned off the right front passenger
frontal airbag.
If, after several seconds, both
status indicator lights remain on,
or if there are no lights at all, there
may be a problem with the lights or
the passenger sensing system. See
your dealer for service.{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light on page 5‑11 for more
information, including important
safety information.
Charging System Light
The charging system light comes on
briefly when the ignition is turned
on, but the engine is not running, as
a check to show the light is working. The light turns off when the engine
is started. If it does not, have the
vehicle serviced by your dealer.
If the light stays on, or comes on
while driving, there may be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery.
When this light comes on, the Driver
Information Center (DIC) also
displays a message.
See
Battery Voltage and Charging
Messages on page 5‑24.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.

Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It ensures that
emissions are at acceptable levels
for the life of the vehicle, helping to
produce a cleaner environment.
This light should come on when the
ignition is on, but the engine is not
running, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer.
If the Malfunction Indicator Lamp
comes on and stays on while the
engine is running, this indicates that
there is an OBD II problem and
service is required.Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system assists
the service technician in correctly
diagnosing any malfunction.
Notice:
If the vehicle is
continually driven with this light
on the emission controls might
not work as well, the vehicle fuel
economy might not be as good,
and the engine might not run
as smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.
Notice: Modifications made
to the engine, transmission,
exhaust, intake, or fuel system
of the vehicle or the replacement
of the original tires with other
than those of the same Tire
Performance Criteria (TPC) can
affect the vehicle's emission
controls and can cause this light
to come on. Modifications to
these systems could lead to
costly repairs not covered by the vehicle warranty. This
could also result in a failure
to pass a required Emission
Inspection/Maintenance test. See
Accessories and Modifications on
page 10‑3.
This light comes on during a
malfunction in one of two ways:
Light Flashing:
A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
To prevent more serious damage to
the vehicle:.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
.If towing a trailer, reduce the
amount of cargo being hauled as
soon as it is possible.

5-14 Instruments and Controls
If the light continues to flash, when
it is safe to do so, stop the vehicle.
Find a safe place to park the
vehicle. Turn the vehicle off, wait at
least 10 seconds, and restart the
engine. If the light is still flashing,
follow the previous steps and see
your dealer for service as soon as
possible.
Light On Steady:An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.
The following may correct an
emission system malfunction:
.Make sure the fuel cap is
fully installed. See Filling the
Tank on page 9‑55. 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.
.Make sure the electrical system
is not wet. The system could be
wet if the vehicle was driven
through a deep puddle of
water. The condition is usually
corrected when the electrical
system dries out. A few driving
trips should turn the light off.
.Make sure to fuel the vehicle
with quality fuel. Poor fuel quality
causes the engine not to run as
efficiently as designed and can
cause: stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these conditions
occurs, change the fuel brand used.
It will require at least one full tank of
the proper fuel to turn the light off.
See Recommended Fuel on
page 9‑52. If none of the above have made
the light turn off, your dealer can
check the vehicle. The dealer
has the proper test equipment
and diagnostic tools to fix any
mechanical or electrical problems
that might have developed.Emissions Inspection and
Maintenance Programs
Some local governments may
have programs to inspect the
on-vehicle emission control
equipment. For the inspection, the
emission system test equipment is
connected to the vehicle’s Data Link
Connector (DLC).
The DLC is under the instrument
panel to the left of the steering
wheel. See your dealer if assistance
is needed.

Black plate (15,1)GMC Terrain Owner Manual - 2011
Instruments and Controls 5-15
The vehicle may not pass
inspection if:
.The Malfunction Indicator Lamp
is on with the engine running,
or if the light does not come on
when the ignition is turned to
ON/RUN while the engine is off.
.The critical emission control
systems have not been
completely diagnosed by the
system. This can happen if
the battery has recently been
replaced or if the battery has run
down. The diagnostic system
evaluates critical emission
control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection, your dealer can
prepare the vehicle for
inspection.
Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working
EnglishMetric
The brake indicator light should
come on briefly as the engine is
started. If it does not come on have
the vehicle serviced by your dealer.
When the ignition is on, the brake
system warning light comes on
when the parking brake is set. The
light stays on if the parking brake
does not fully release. If it stays on after the parking brake is fully
released, there is a brake problem.
Have the brake system inspected
immediately.
{WARNING
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
If the light comes on while driving, a
chime sounds. Pull off the road and
stop. The pedal might be harder
to push or go closer to the floor.
It might also take longer to stop.
