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.

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.
If the light is still on, have the
vehicle towed for service. See
Towing the Vehicle on page 10‑79.

Vehicle Messages
Messages are displayed on the DIC
to notify the driver that the status of
the vehicle has changed and that
some action may be needed by
the driver to correct the condition.
Multiple messages may appear one
after another.
Some messages may not require
immediate action, but you can press
SET/CLR to acknowledge that you
received the messages and to
clear them from the display. Some
messages cannot be cleared from
the DIC display because they are
more urgent. These messages
require action before they can be
cleared. You should take any
messages that appear on the
display seriously and remember
that clearing the messages will only
make the messages disappear, not
correct the problem. You will find
the possible messages that can be
displayed and some information
about them grouped by subject in
the following information.
Battery Voltage and
Charging Messages
BATTERY SAVER ACTIVE
This message displays when the
vehicle has detected that the
battery voltage is dropping beyond
a reasonable point. The battery
saver system starts reducing certain
features of the vehicle that you may
be able to notice. At the point that
features are disabled, this message
is displayed. It means that the
vehicle is trying to save the charge
in the battery. Turn off unnecessary
accessories to allow the battery to
recharge.

Lighting Features
Entry Lighting
The dome lamp, cargo lamp, and
foot lamp inside the vehicle come
on when any door is opened, if the
dome lamp is in the door position.
In addition, these lamps come on
when the Remote Keyless Entry
(RKE) unlock button is pressed.
They stay on for 20 seconds or until
a door is opened. After the door is
opened and then closed, the light
remains on for 20 seconds, or until
the ignition is turned to ON/RUN.
Battery Load
Management
The vehicle has Electric Power
Management (EPM) that estimates
the battery's temperature and state
of charge. It then adjusts the voltage
for best performance and extended
life of the battery. When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), you may see the
voltage move up or down. This is
normal. If there is a problem, an
alert will be displayed.
The battery can be discharged at
idle if the electrical loads are very
high. This is true for all vehicles.
This is because the generator
(alternator) may not be spinning
fast enough at idle to produce all
of the power needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on,
such as: headlamps, high beams,
fog lamps, rear window defogger,
climate control fan at high speed,
heated seats, engine cooling fans,
trailer loads, and loads plugged into
accessory power outlets.

Black plate (6,1)GMC Terrain Owner Manual - 2011
6-6 Lighting
EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs.
It can increase engine idle speed to
generate more power whenever
needed. It can temporarily reduce
the power demands of some
accessories.
Normally, these actions occur in
steps or levels, without being
noticeable. In rare cases at the
highest levels of corrective action,
this action may be noticeable to the
driver. If so, a DIC message might
be displayed, such as BATTERY
SAVER ACTIVE, BATTERY
VOLTAGE LOW, or LOW BATTERY.
If one of these messages displays,
it is recommended that the driver
reduce the electrical loads as much
as possible. SeeDriver Information
Center (DIC) on page 5‑20.

7-34 Infotainment System
In severe or extreme weather
conditions, the RSE system may not
work until the temperature is within
the operating range. The operating
range is above−20°C (−4°F)
and below 60°C (140°F). If the
temperature is outside of this range,
heat or cool the vehicle until it is
