136 Lighting
Daytime Running
Lamps (DRL)
DRL can make it easier for others to
see the front of your vehicle during
the day.
The low-beam headlamps or
dedicated DRL, if equipped, come
on at a reduced brightness in
daylight when the following
conditions are met:
.The ignition is on.
. The exterior lamp control is
in AUTO.
. The transmission is not in
P (Park).
. The light sensor determines it is
daytime.
. The parking brake is released.
Fully functional 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 cluster will be lit. When the exterior lamp control is
turned to
5, 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.
For vehicles first sold in the United
States or Mexico, the DRL can also
be turned off by turning the lamp
control counterclockwise. The DRL
will stay off until the next ignition
cycle.
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.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it
is light outside when the vehicle
leaves the garage, there is a slight
delay before the automatic
headlamp system changes to the

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 sensors are not clean. Keep
the vehicle's rear bumper free of
mud, dirt, snow, ice, and slush.
For cleaning instructions, see
Exterior Care 0269.
. 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 RPA
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, RPA 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.
Forward Collision Alert
(FCA) System
If equipped, the FCA system may
help to avoid or reduce the harm
caused by front-end crashes. When
approaching a vehicle ahead too
quickly, FCA provides a red flashing
alert and rapidly beeps. FCA also
lights a red visual alert if following
another vehicle much too closely.
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. It also may not
provide any warning at all. FCA
does not warn of pedestrians,

animals, signs, guardrails,
bridges, construction barrels,
or other objects. Be ready to take
action and apply the brakes. See
Defensive Driving0150.
FCA can be disabled with the FCA
steering wheel control.
Detecting the Vehicle Ahead
FCA warnings will not occur unless
the FCA system detects a vehicle
ahead. When a vehicle is detected,
the vehicle ahead indicator will
display green. Vehicles may not be
detected on curves, highway exit
ramps, or hills, due to poor visibility;
or if a vehicle ahead is partially
blocked by pedestrians or other objects. FCA 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,
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 detected vehicle too rapidly,
the red FCA display will flash and
sound several high-pitched beeps
from the front. When this Collision
Alert occurs, the brake system may
prepare for driver braking to occur
more rapidly which can cause a
brief, mild deceleration. Continue to
apply the brake pedal as needed.
Cruise control may be disengaged
when the Collision Alert occurs.
Tailgating Alert
The red Collision Alert display will
stay continuously illuminated when
following a detected vehicle ahead
much too closely.

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. See Buying
New Tires 0250.
. 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. A TPMS relearn tool
can also be purchased. See Tire
Pressure Monitor Sensor Activation
Tool at
www.gmtoolsandequipment.com or
call 1-800-GM TOOLS
(1-800-468-6657).
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.
4. Press the SET/CLR button to begin the sensor matching
process.
A message requesting
acceptance of the process
should display.
5. Press the SET/CLR button again to confirm the selection.
The horn sounds twice to
signal the receiver is in relearn
mode and the TIRE
LEARNING ACTIVE message
displays on the DIC screen.
6. Start with the driver side front tire.

254 Vehicle Care
Wheel Replacement
Replace any wheel that is bent,
cracked, or badly rusted or
corroded. If wheel nuts keep coming
loose, the wheel, wheel bolts, and
wheel nuts should be replaced.
If the wheel leaks air, replace it.
Some aluminum wheels can be
repaired. See your dealer if any of
these conditions exist.
Your dealer will know the kind of
wheel that is needed.
Each new wheel should have the
same load-carrying capacity,
diameter, width, offset, and be
mounted the same way as the one it
replaces.
Replace wheels, wheel bolts, wheel
nuts, or Tire Pressure Monitor
System (TPMS) sensors with new
GM original equipment parts.
{Warning
Using the wrong replacement
wheels, wheel bolts, or wheel
nuts can be dangerous. It could(Continued)
Warning (Continued)
affect the braking and handling of
the vehicle. Tires can lose air,
and cause loss of control, causing
a crash. Always use the correct
wheel, wheel bolts, and wheel
nuts for replacement.
Caution
The wrong wheel can also cause
problems with bearing life, brake
cooling, speedometer or
odometer calibration, headlamp
aim, bumper height, vehicle
ground clearance, and tire or tire
chain clearance to the body and
chassis.
Used Replacement Wheels
{Warning
Replacing a wheel with a used
one is dangerous. How it has
been used or how far it has been
driven may be unknown. It could
fail suddenly and cause a crash.
When replacing wheels, use a
new GM original equipment
wheel.
Tire Chains
{Warning
Do not use tire chains. There is
not enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance can
cause damage to the brakes,
suspension or other vehicle parts.
The area damaged by the tire
chains could cause you to lose
control of the vehicle and you or
others may be injured in a crash.
