Drive Systems
All-Wheel Drive
Vehicles with this feature always
send engine power to all four
wheels. It is fully automatic, and
adjusts itself as needed for road
conditions.
When using a compact spare tire on
an AWD vehicle, the system
automatically detects the compact
spare and disables AWD. To restore
AWD operation and prevent
excessive wear on the system,
replace the compact spare with a
full-size tire as soon as possible.
See Compact Spare Tire on
page 10‑75 for more information.
Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
even be noticed that the brake
pedal moves a little. This is normal.
If there is a problem with ABS, this
warning light stays on. See Antilock
Brake System (ABS) Warning Light
on page 5‑17.

Black plate (34,1)GMC Terrain Owner Manual (Include Mex) - 2012
9-34 Driving and Operating
If the ignition is on, the brake
system warning light will come on.
SeeBrake System Warning Light on
page 5‑16.
Notice: Driving with the parking
brake on can overheat the brake
system and cause premature
wear or damage to brake system
parts. Make sure that the parking
brake is fully released and the
brake warning light is off before
driving.
To release the parking brake, hold
the regular brake pedal down, then
push down momentarily on the
parking brake pedal until you feel
the pedal release. Slowly pull your
foot up off the park brake pedal.
If the parking brake is not released
when you begin to drive, the brake
system warning light will be on and
a chime will sound warning you that
the parking brake is still on.
If you are towing a trailer and are
parking on a hill, see Driving
Characteristics and Towing Tips on
page 9‑57.Brake Assist
This vehicle has a brake assist
feature designed to assist the driver
in stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle. The
stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.
Minor brake pedal pulsation or
pedal movement during this time is
normal and the driver should
continue to apply the brake pedal as
the driving situation dictates. The
brake assist feature will
automatically disengage when the
brake pedal is released or brake
pedal pressure is quickly
decreased.
Hill Start Assist (HSA)
This vehicle has a Hill Start Assist
(HSA) feature, which may be useful
when the vehicle is stopped on a
grade. This feature is designed to
prevent the vehicle from rolling,
either forward or rearward, during
vehicle drive off. After the driver
completely stops and holds the
vehicle in a complete standstill on a
grade, HSA will be automatically
activated. During the transition
period between when the driver
releases the brake pedal and starts
to accelerate to drive off on a grade,
HSA holds the braking pressure to
ensure that there is no rolling. The
brakes will automatically release
when the accelerator pedal is
applied within the two‐second
window. It will not activate if the
vehicle is in a drive gear and facing
downhill or if the vehicle is facing
uphill and in R (Reverse).

9-38 Driving and Operating
Cruise Control
With cruise control, the vehicle can
maintain a speed of about 40 km/h
(25 mph) or more without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below 40 km/h (25 mph).
If the brakes are applied, the cruise
control is disengaged.
If the vehicle has the StabiliTrak
®
system and begins to limit wheel
spin while using cruise control, the
cruise control automatically
disengages. SeeStabiliTrak
®
System on page 9‑36 orTraction
Control System (TCS) on
page 9‑35. When road conditions
allow you to safely use it again, the
cruise control can be turned
back on.
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
ON/OFF5CRUISE: Press to turn
the cruise control system on and off.
*CANCEL: Press to disengage
cruise control without erasing the
set speed from memory.
RES/+ (Resume/Accel): Move the
thumbwheel up toward RES/+ to
make the vehicle resume to a
previously set speed or to
accelerate.

Driving and Operating 9-41
The forward-looking FCA camera
sensor is on the windshield ahead
of the rearview mirror. FCA detects
vehicles within a distance of
approximately 60 m (197 ft) and
operates at speeds above 40 km/h
(25 mph).
{WARNING
FCA is a warning system and
does not apply the brakes. When
approaching a slower-moving or
stopped vehicle ahead too rapidly,
or when following a vehicle too
closely, FCA may not provide
enough time to avoid a crash.
FCA does not warn of any objects
that do not look like a vehicle to
the FCA camera sensor, such as
pedestrians, animals, signs,
guardrails, bridges, construction
barrels, or other objects. Be ready
to take action and apply the
brakes. For more information, see
Defensive Driving on page 9‑3.
{WARNING
There are conditions where FCA
may not detect a vehicle ahead.
These include winding roads or
weather conditions such as fog,
rain, or snow that can limit
visibility. You could crash into a
vehicle ahead. Do not rely on
FCA on winding roads or in poor
visibility conditions.Collision Alert
When your vehicle approaches
another vehicle too rapidly, the red
FCA display will flash and sound
several beeps. When this occurs,
the brake system prepares for driver
braking to occur more rapidly.
Continue to apply the brake pedal
as the driving situation dictates.
Tailgating Alert
The red FCA display will stay
continuously illuminated if the
vehicle ahead remains much too
close.

Selecting the Alert Timing
The Collision Alert control is on the
steering wheel. Press COLLISION
ALERT to set the alert timing to far,
medium, near or off. The first button
press shows the current control
setting on the DIC. Additional button
presses will change this setting. The
chosen setting will remain until it is
changed and will affect both the
Collision Alert and the Tailgating
Alert features. The timing of both
alerts will vary based on vehicle
speed. The faster the vehicle speed,
the further away the alert will occur.Consider traffic and weather
conditions when selecting the alert
timing. The range of selectable alert
timing may not be appropriate for all
drivers and driving conditions.
Detecting the Vehicle Ahead
The green vehicle ahead indicator
will appear when a vehicle is
detected ahead. Whenever this
indicator does not appear, FCA will
not respond. The indicator may
disappear on curves, highway exit
ramps, or hills, or due to poor
visibility. The FCA system will not
detect another vehicle ahead until it
is completely in the driving lane.
{WARNING
If the FCA camera sensor is
blocked by dirt, snow, or ice, or if
the windshield is damaged, it may
not detect a vehicle ahead. FCA
may not help avoid a collision
under these conditions. Do not
rely on FCA when the camera is
blocked by snow, ice, or dirt.
Keep the windshield clean.
{WARNING
If the headlamps are not cleaned
or properly aimed, the FCA
system may not detect a vehicle
ahead. FCA may not help avoid a
collision under these conditions.
Keep the headlamps clean and
properly aimed.

Driving and Operating 9-43
Unnecessary Alerts
FCA may sometimes set
unnecessary alerts to turning
vehicles, vehicles in other lanes,
objects that are not vehicles,
or shadows. These alerts are
normal operation and the vehicle
does not need service.
Other Messages
There are messages that may
appear on the Driver Information
Center (DIC) in the instrument
cluster to provide information about
FCA. SeeObject Detection System
Messages on page 5‑29.
Cleaning the System
If the FCA system does not seem to
operate properly, clean the outside
of the windshield area in front of the
camera sensor before considering
taking the vehicle in for service.
Ultrasonic Parking Assist
For vehicles with the Ultrasonic
Rear Parking Assist (URPA) system,
it assists the driver with parking and
avoiding objects while in
R (Reverse). URPA operates at
speeds less than 8 km/h (5 mph),
and the sensors on the rear bumper
detect objects up to 2.5 m (8 ft)
behind the vehicle, and at least
20 cm (8 in) off the ground.
{WARNING
The URPA system does not
detect pedestrians, bicyclists,
animals, or any other objects
located below the bumper or that
are too close or too far from the
vehicle. To prevent injury, death,
or vehicle damage, even with
URPA, always check behind the
vehicle and check all mirrors
before backing.
How the System Works
URPA comes on automatically when
the shift lever is moved into
R (Reverse). A single tone sounds
to indicate the system is working.
URPA operates only at speeds less
than 8 km/h (5 mph).
An obstacle is indicated by audible
beeps. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in) the beeping is a
continuous tone for five seconds.
To be detected, objects must be at
least 20 cm (8 in) off the ground and
below liftgate level. Objects must
also be within 2.5 m (8 ft) from the
rear bumper. The distance objects
can be detected may be less during
warmer or humid weather.

Rear Vision
Camera (RVC)
The vehicle may have a Rear Vision
Camera (RVC) system. Read this
entire section before using it.
The RVC can assist the driver when
backing up by displaying a view of
the area behind the vehicle.
{WARNING
The RVC system does not display
pedestrians, bicyclists, animals,
or any other object located
outside the camera's field of view,
below the bumper, or under the
vehicle.
Do not back the vehicle using
only the RVC screen or by using
the screen during longer, higher
speed backing maneuvers,
or where there could be(Continued)
WARNING (Continued)
cross-traffic. Perceived distances
may be different from actual
distances.
Failure to use proper care before
backing may result in injury,
death, or vehicle damage. Always
check before backing by checking
behind and around the vehicle.
An image appears on the radio
screen with the message Check
Surroundings for Safety when the
vehicle is shifted into R (Reverse).
