198 DRIVING AND OPERATING
Braking in Emergencies
ABS allows steering and braking at the
same time. In many emergencies,
steering can help even more than
braking.
Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The EPB can always be
activated, even if the ignition is off. To
prevent draining the battery, avoid
repeated cycles of the EPB system
when the engine is not running.The system has a
Y,f, or PARK
Electric Parking Brake light, and a
8
Service Parking Brake light. See
Electric Parking Brake Light 0122 and
Service Electric Parking Brake Light
0 123.
Before leaving the vehicle, check
for the
Y,f, or PARK light to
ensure that the parking brake is
applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Press the EPB switch momentarily.
The
Y,f, or PARK light will flash
and then stay on once the EPB is fully
applied. If the
Y,f, or PARK light
flashes continuously, then the EPB is
only partially applied or there is a
problem with the EPB. A DIC message
will display. Release the EPB and try
to apply it again. If the light does not
come on, or keeps flashing, have the
vehicle serviced. Do not drive the vehicle if the
Y,f, or PARK light is
flashing. See your dealer. See Electric
Parking Brake Light 0122.
If the
8light is on, press the EPB
switch and hold it. Continue to hold
the switch until the
Y,f, or PARK
light remains on. If the
8light
remains on, see your dealer.
If the EPB is applied while the vehicle
is moving, the vehicle will decelerate
as long as the switch is pressed. If the
switch is pressed until the vehicle
comes to a stop, the EPB will remain
applied.
The vehicle may automatically apply
the EPB in some situations when the
vehicle is not moving. This is normal,
and is done to periodically check the
correct operation of the EPB system.
If the EPB fails to apply, block the rear
wheels to prevent vehicle movement.

232 DRIVING AND OPERATING
some very low speed pedestrian
crashes or reduce pedestrian injury.
FPB can automatically brake to
detected pedestrians between 8 km/h
(5 mph) and 80 km/h (50 mph).
Automatic braking levels may be
reduced under certain conditions,
such as higher speeds.
If this happens, Automatic Braking
may engage the Electric Parking Brake
(EPB) to hold the vehicle at a stop.
Release the EPB. A firm press of the
accelerator pedal will also release
Automatic Braking and the EPB.
{Warning
FPB may alert or automatically
brake the vehicle suddenly in
situations where it is unexpected
and undesired. It could falsely alert
or brake for objects similar in shape
or size to pedestrians, including
shadows. This is normal operation
and the vehicle does not need
service. To override Automatic
Braking, firmly press the accelerator
pedal, if it is safe to do so.Automatic Braking can be disabled
through vehicle personalization. See
“Front Pedestrian Detection
”in
“Collision/Detection Systems” under
Vehicle Personalization 0135.
{Warning
Using the Front Pedestrian Braking
system while towing a trailer could
cause you to lose control of the
vehicle and crash. Turn the system
to Alert or Off when towing a
trailer.
Cleaning the System
If FPB does not seem to operate
properly, cleaning the outside of the
windshield in front of the rearview
mirror may correct the issue.
Night Vision System
If equipped, this system can help the
driver see and alert the driver to
pedestrians or large animals ahead of
the vehicle beyond the area lit by the
headlamps. A thermal heat image of
the view ahead is displayed when it is dark enough outside. If a pedestrian
or large animal is detected more than
25 m (82 ft) away, an amber
pedestrian or animal icon displays and
a box appears around the pedestrian
or animal. When the system detects
that the vehicle is approaching a
pedestrian ahead much too quickly,
the box changes to red.
With the Front Pedestrian Braking
system turned on, Night Vision
provides a red Head-Up Display (HUD)
alert when the system detects that the
vehicle is approaching a pedestrian
ahead much too quickly. In addition,
an alert beeps or the Safety Alert Seat
pulses, if equipped. See
Front
Pedestrian Braking (FPB) System 0230.

234 DRIVING AND OPERATING
System pedestrian icons, beeps, and
(if equipped) Safety Alert Seat pulses
can be set to Off through vehicle
personalization by turning off the
Front Pedestrian Braking system. See
“Front Pedestrian Detection”in
“Collision/Detection Systems” under
Vehicle Personalization 0135.
{Warning
The Night Vision system does not
automatically brake the vehicle.
It does not provide alerts unless it
detects a pedestrian or large
animal. The system may not detect
pedestrians, including children,
or animals:
. If they are less than 25 m
(82 ft) away.
. If they are not directly ahead
in the sensor coverage area,
fully visible, standing upright,
or part of a group.
(Continued)
Warning (Continued)
.If the person or animal is
moving too quickly through
the field of view, such as a
bicyclist.
. If the pedestrian is wearing
certain types of clothing.
. If headlamps are off, except
when parked.
. If the outside temperature is
higher than 30 °C (86 °F).
. Due to poor visibility,
including in heavy fog, rain,
or snow.
. If the sensor is blocked by
dirt, snow, rain, or ice.
Be ready to take action and apply
the brakes. For more information,
see Defensive Driving 0166. Keep
the Night Vision sensor clean and
in good repair. Pedestrian detection may not be
available in high outside temperatures.
An amber icon,*, displays. The
system does not need service.
In rain, snow, or fog the image may
not be clear and the direction of the
road ahead may not be seen. In more
severe weather conditions, the image
may be unclear and unusable. The
system does not need service.
Keep the system sensor clean by
activating the rear window washer
when it is dark enough for the system
to operate. If the Night Vision image
still looks blurry, use a soft wet cloth
to gently clean the sensor camera lens
and dry thoroughly. The sensor is
behind the front grille to the inside of
the driver side headlamp.
The camera must also be aligned to
work correctly. If the camera needs
adjustment, see your dealer. Do not
attempt to adjust the camera yourself.

The TPMS will not activate the tire fill
alert properly under the following
conditions:
.There is interference from an
external device or transmitter.
. The air pressure from the inflation
device is not sufficient to inflate
the tire.
. There is a malfunction in
the TPMS.
. There is a malfunction in the horn
or turn signal lamps.
. The identification code of the
TPMS sensor is not registered to
the system.
. The battery of the TPMS sensor
is low.
If the tire fill alert does not operate
due to TPMS interference, move the
vehicle about 1 m (3 ft) back or
forward and try again. If the tire fill
alert feature is not working, use a tire
pressure gauge.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
vehicle’s 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 tire. 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. Place the vehicle in Service Mode. See Ignition Positions
0 180.
3. Make sure the Tire Pressure info display option is turned on. The
info displays on the DIC can be
turned on and off through the
Options menu. See Driver
Information Center (DIC) 0128.
4. Use the five-way DIC control on the right side of the steering
wheel to scroll to the Tire
Pressure screen under the DIC
info page. See Driver Information
Center (DIC) 0128.
5. Press and hold the thumbwheel in the center of the five-way DIC
control.

310 VEHICLE CARE
Caution
If the vehicle is equipped with a tire
size other than 265/45R21, use tire
chains only where legal and only
when necessary. Use low profile
chains that add no more than
12 mm thickness to the tire tread
and inner sidewall. Use chains that
are the proper size for the tires.
Install them on the tires of the
front axle. Do not use chains on the
tires of the rear axle. Tighten them
as tightly as possible with the ends
securely fastened. Drive slowly and
follow the chain manufacturer's
instructions. If the chains contact
the vehicle, stop and retighten
them. If the contact continues, slow
down until it stops. Driving too fast
or spinning the wheels with chains
on will damage the vehicle.
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires are
maintained properly. SeeTires0289. If air goes out of a tire, it is much
more likely to leak out slowly. But if
there ever is a blowout, here are a few
tips about what to expect and what
to do:
If a front tire fails, the flat tire creates
a drag that pulls the vehicle toward
that side. Take your foot off the
accelerator pedal and grip the steering
wheel firmly. Steer to maintain lane
position, and then gently brake to a
stop, well off the road, if possible.
A rear blowout, particularly on a
curve, acts much like a skid and may
require the same correction as used in
a skid. Stop pressing the accelerator
pedal and steer to straighten the
vehicle. It may be very bumpy and
noisy. Gently brake to a stop, well off
the road, if possible.
{Warning
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
(Continued)
Warning (Continued)
underinflated or flat may cause a
blowout and a serious crash. Never
attempt to re-inflate a tire that has
been driven on while severely
underinflated or flat. Have your
dealer or an authorized tire service
center repair or replace the flat tire
as soon as possible.
{Warning
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the appropriate
safety equipment and training. If a
jack is provided with the vehicle, it
is designed only for changing a flat
tire. If it is used for anything else,
you or others could be badly injured
or killed if the vehicle slips off the
jack. If a jack is provided with the
vehicle, only use it for changing a
flat tire.
