Black plate (2,1)GMC Terrain/Terrain Denali Owner Manual - 2013 - crc 1st edition - 5/8/12
6-2 Lighting
This indicator light turns on in the
instrument panel cluster when the
high‐beam headlamps are on.
Flash-to-Pass
The flash‐to‐pass feature works with
the low beams or Daytime Running
Lamps (DRL) on or off.
To flash the high beams, pull the
turn signal/lane change lever all the
way toward you, then release it.
Daytime Running
Lamps (DRL)
Daytime Running Lamps (DRL)
system makes the low-beam
headlamps come on at a reduced
brightness in daylight when the
following conditions are met:
.The ignition is on.
.The exterior lamp band is in the
automatic position.
.The transmission is not in
P (Park).
.The light sensor determines it is
daytime.
.The parking brake is released.
Fully functional Daytime Running
Lamps (DRL) are required on all
vehicles first sold in Canada.
When the DRL are on the taillamps,
sidemarker, instrument panel lights
and other lamps will not be on. The
instrument panel cluster will be lit.
When the exterior lamp band is
turned to the headlamp position, the
low-beam headlamps come on. The
other lamps that come on with the
headlamps will also come on.
To idle your vehicle with the DRL
off, move the shift lever to P (Park).
The DRL will stay off until the shift
lever is moved out of the P (Park)
position. The regular headlamp system
should be turned on when needed.
Automatic Headlamp
System
When it is dark enough outside, the
headlamps come on automatically.
Do not cover the light sensor on top
of the instrument panel or the
headlamps will come on when they
are not needed.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.

Object Detection
Systems
Forward Collision Alert
(FCA) System
For vehicles with this feature, read
the following section before using it.
The Forward Collision Alert (FCA)
system may help to avoid or reduce
the harm caused by front-end
crashes. FCA provides a flashing
visual alert and beeps when
approaching a vehicle directly
ahead too quickly. FCA also
provides a visual alert if following
another vehicle much too closely.
The FCA symbol is on top of the
instrument panel to the right of the
steering wheel. 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 a
warning with enough time to help
avoid a crash. FCA does not warn
of 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.

9-38 Driving and Operating
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
FCA does not provide a warning
to help avoid a crash, unless it
detects a vehicle. FCA may not
detect a vehicle ahead if the FCA
sensor is blocked by dirt, snow,(Continued)
WARNING (CONTINUED)
or ice, or if the windshield is
damaged. It may also not detect a
vehicle on winding or hilly roads,
or in conditions that can limit
visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in
proper condition. Keep the
windshield, headlamps, and FCA
sensors clean and in good repair.
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

9-40 Driving and Operating
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.
Turning the System On and Off
The URPA system can be turned on
and off using the infotainment
system controls. SeeVehicle
Personalization on page 5‑31 for
more information.
When the system is off, PARK
ASSIST OFF displays on the Driver
Information Center (DIC). The
message disappears after a short
period of time.
URPA defaults to the on setting
each time the vehicle is started.
When the System Does Not
Seem to Work Properly
The following messages may be
displayed on the DIC:
SERVICE PARKING ASSIST: If
this message occurs, check the
following conditions:
.The ultrasonic sensors are not
clean. Keep the vehicle's rear
bumper free of mud, dirt, snow,
ice, and slush. For cleaning
instructions, see Exterior Care
on page 10‑73.
.The park assist sensors are
covered by frost or ice. Frost or
ice can form around and behind
the sensors and may not always
be seen; this can occur after
washing the vehicle in cold
weather. The message may not
clear until the frost or ice has
melted.
If the above conditions do not exist,
take the vehicle to your dealer to
repair the system. PARK ASSIST OFF:
If the URPA
system does not activate due to a
temporary condition, the message
displays on the DIC. This can occur
under the following conditions:
.The driver has disabled the
system.
.A trailer was attached to the
vehicle, or an object was
hanging out of the liftgate during
the last drive cycle. Once the
object is removed, URPA will
return to normal operation.
.A tow bar is attached to the
vehicle.
.The bumper is damaged. Take
the vehicle to your dealer to
repair the system.
.Other conditions, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck, are affecting
system performance.

.The TPMS sensor matching
process was not done or not
completed successfully after
rotating the tires. The
malfunction light and the DIC
message should go off after
successfully completing the
sensor matching process. See
"TPMS Sensor Matching
Process" later in this section
.One or more TPMS sensors are
missing or damaged. The DIC
message and the TPMS
malfunction light should go off
when the TPMS sensors are
installed and the sensor
matching process is performed
successfully. See your dealer for
service.
.Replacement tires or wheels do
not match the original equipment
tires or wheels. Tires and wheels
other than those recommended
could prevent the TPMS from
functioning properly. SeeBuying
New Tires on page 10‑53.
.Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning
properly, it cannot detect or signal a
low tire condition. See your dealer
for service if the TPMS malfunction
light and DIC message comes on
and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a new
tire/wheel position after rotating the
tires or replacing one or more of the
TPMS sensors. The TPMS sensor
matching process should also be
performed after replacing a spare
tire with a road tire containing the
TPMS sensor. The malfunction light
and the DIC message should go off
at the next ignition cycle. The
sensors are matched to the tire/
wheel positions, using a TPMS relearn tool, in the following order:
driver side front tire, passenger side
front tire, passenger side rear tire,
and driver side rear. See your
dealer for service or to purchase a
relearn tool.
There are two minutes to match the
first tire/wheel position, and
five minutes overall to match all four
tire/wheel positions. If it takes
longer, the matching process stops
and must be restarted.
The TPMS sensor matching
process is:
1. Set the parking brake.
2. Turn the ignition to ON/RUN with
the engine off.
3. Use the MENU button to select the Vehicle Information Menu in
the Driver Information Center
(DIC). Use the arrow keys to
scroll to the Tire Pressure
screen.
