2010 GMC TERRAIN warning light

Seats and Restraints 2-35
The passenger sensing system is
designed to turn off the right front
passenger frontal airbag if:
.The right front passenger seat
is unoccupied.
.The system determines that an
infant is present in a child
restraint.
.A right front passenger takes
his/her weight off of the seat for
a period of time.
.Or, if there is a critical problem
with the airbag system or the
passenger sensing system.
When the passenger sensing
system has turned off the right front
passenger frontal airbag, the off
indicator will light and stay lit to
remind you that the airbag is off.
See Passenger Airbag Status
Indicator on page 4‑15. The passenger sensing system is
designed to turn on (may inflate)
the right front passenger frontal
airbag anytime the system senses
that a person of adult size is
sitting properly in the right front
passenger seat.
When the passenger sensing
system has allowed the airbag to be
enabled, the on indicator will light
and stay lit to remind you that the
airbag is active.
For some children, including
children in child restraints, and for
very small adults, the passenger
sensing system may or may not
turn off the right front passenger
frontal airbag, depending upon
the person’
s seating posture
and body build. Everyone in the
vehicle who has outgrown child
restraints should wear a safety belt
properly —whether or not there is
an airbag for that person.
{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. See Airbag Readiness
Light
on page 4‑15for more
information, including important
safety information.

2-38 Seats and Restraints
If the passenger seat gets wet, dry
the seat immediately. If the airbag
readiness light is lit, do not install a
child restraint or allow anyone to
occupy the seat. SeeAirbag
Readiness Light
on page 4‑15for
important safety information.
The on indicator may be lit if an
object, such as a briefcase,
handbag, grocery bag, laptop or
other electronic device, is put on an
unoccupied seat. If this is not
desired remove the object from
the seat.
{WARNING
Stowing of articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle
should be serviced. There are parts
of the airbag system in several
places around the vehicle. Your
dealer/retailer and the service
manual have information about
servicing the vehicle and the airbag
system. To purchase a service
manual, see Service Publications
Ordering Information on page 12‑12.
{WARNING
For up to 10 seconds after the
ignition is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
(Continued)
WARNING (Continued)
They are probably part of the
airbag system. Be sure to follow
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Q: Is there anything I might addto or change about the vehicle
that could keep the airbags
from working properly?
A: Yes. If you add things that
change the vehicle's frame,
bumper system, height, front end
or side sheet metal, they may
keep the airbag system from
working properly. Changing or
moving any parts of the front
seats, safety belts, the airbag
sensing and diagnostic module,

accessory or accessory bracket
from the plug because the power
outlets are designed for
accessory power plugs only.Warning Lights,
Gauges, and
Indicators
Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the engine is started
to indicate they are working.
Gauges can indicate when there
could be a problem with a vehicle
function. Often gauges and warning
lights work together to indicate a
problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gauges
shows there may be a problem,
check the section that explains what
to do. Follow this manual's advice.
Waiting to do repairs can be costly
and even dangerous.

Instruments and Controls 4-13
Speedometer
The vehicle's speed can be selected
to display on the Driver Information
Center (DIC) and the speedometer
in either kilometers per hour (km/h)
or miles per hour (mph). Telltales on
the speedometer indicate whether
kilometers or miles were chosen.
The DIC will show the vehicles
speed after the limit on the
speedometer has been reached.
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
This vehicle has a tamper-resistant
odometer. If the vehicle needs a
new odometer installed, the new
one is set to the mileage of the old
odometer. If this is not possible, it is
set at zero and a label is put on the
driver's door to show the old
mileage reading.
Tachometer
The tachometer displays the engine
speed in revolutions per
minute (rpm).
Notice:If the engine is operated
with the tachometer in the shaded
warning area, the vehicle could
be damaged, and the damages
would not be covered by the
vehicle warranty. Do not operate
the engine with the tachometer in
the shaded warning area.
Fuel Gauge
United StatesCanada
When the ignition is on, the fuel
gauge shows about how much fuel
the vehicle has left in the fuel tank. An arrow on the fuel gauge
indicates the side of the vehicle
the fuel door is on.
The gauge will first indicate empty
before the vehicle is out of fuel and
the low fuel light comes on, but the
vehicle's fuel tank should be
filled soon.
Here are some situations that can
occur with the fuel gauge. None of
these indicate a problem with the
fuel gauge.
.At the service station, the fuel
pump shuts off before the gauge
reads full.
.It takes a little more or less fuel
to fill up than the gauge
indicated. For example, the
gauge may have indicated the
tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.

Instruments and Controls 4-15
This cycle repeats if the passenger
remains unbuckled and the vehicle
is moving.
