2010 GMC TERRAIN engine

4-18 Instruments and Controls
The following can 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.
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 key off, wait at
least 10 seconds, and restart the
engine. If the light is still flashing,
follow the previous steps and see
your dealer/retailer 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. An emission system malfunction
might be corrected.
.Make sure the fuel cap is fully
installed. See
Filling the Tankon
page 8‑56. 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.
.If the vehicle has been driven
through a deep puddle of water,
the vehicle's electrical system
might be wet. 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 may
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 8‑54.
If none of the above have made
the light turn off, your dealer/retailer
can check the vehicle. The
dealer/retailer 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 state/provincial and local
governments have or might begin
programs to inspect the emission
control equipment on the vehicle.
Failure to pass this inspection could
prevent getting a vehicle
registration.
Here are some things to know to
help the vehicle pass an inspection:
.The vehicle will not pass this
inspection if the check engine
light is on with the engine
running, or if the key is in
ON/RUN and the light is not on.
.The vehicle will not pass this
inspection if the OBD II
(on-board diagnostic) system
determines that critical emission
control systems have not been
completely diagnosed by the
system. The vehicle would be
considered not ready for
inspection. This can happen if
the battery has recently been
replaced or if the battery has run
down. The diagnostic system is
designed to evaluate 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 for lack of OBD II
system readiness, your dealer/
retailer can prepare the vehicle
for inspection.Brake System Warning
Light
United StatesCanada
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/
retailer.

4-20 Instruments and Controls
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.
If the light is still on, have the
vehicle towed for service. See
Towing the Vehicle on page 9‑81.
Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light comes on
briefly when the engine is started.
If the light does not come on, have it
fixed so it will be ready to warn if
there is a problem. If the ABS light stays on, turn the
ignition off. If the light comes on
while driving, stop as soon as it is
safely possible and turn the ignition
off. A chime may also sound when
the light comes on steady. Then
start the engine again to reset the
system. If the ABS light stays on,
or comes on again while driving, the
vehicle needs service. If the regular
brake system warning light is not
on, the vehicle still has brakes, but
not antilock brakes. If the regular
brake system warning light is also
on, the vehicle does not have
antilock brakes and there is a
problem with the regular brakes.

Tire Pressure Light
For vehicles with a tire pressure
monitoring system, this light comes
on briefly when the engine is
started. It provides information
about tire pressures and the Tire
Pressure Monitoring System.
When the Light is On Steady
This indicates that one or more of
the tires are significantly
underinflated. A tire pressure message in the
Driver Information Center (DIC), can
accompany the light. See
Tire
Messages
on page 4‑35for more
information. Stop as soon as
possible, and inflate the tires to the
pressure value shown on the tire
loading information label. See Tire
Pressure
on page 9‑52for more
information.
When the Light Flashes First and
Then is On Steady
This indicates that there may be a
problem with the Tire Pressure
Monitor System. The light flashes
for about a minute and stays on
steady for the remainder of the
ignition cycle. This sequence
repeats with every ignition cycle.

Engine Oil Pressure Light
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.

schedule in this manual for
changing engine oil.
The oil pressure light should come
on briefly as the engine is started.
If it does not come on have the
vehicle serviced by your dealer/

If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem. See
your dealer/retailer.
