Flash-to-Pass This feature is used to signal to the
vehicle ahead that you want
to pass.
If the headlamps are off or in the
low ‐ beam position, pull the turn
signal lever toward you to
momentarily switch to high beams.
Release the lever to turn the
high-beam headlamps off.
Daytime Running
Lamps (DRL) DRL can make it easier for others to
see the front of your vehicle during
the day.
A light sensor on top of the
instrument panel makes the DRL
work, so be sure it is not covered. The DRL system makes the
low-beam headlamps come on at a
reduced brightness when the
following conditions are met: .
The ignition is in the ON
position. .
The exterior lamp control is in
the OFF position. .
The parking brake is released.
If the parking brake is applied
before the engine is started, the
DRL do not come on.
When the DRL are on, only the
low-beam headlamps, at a reduced
level of brightness, will be on. The
taillamps, sidemarker, instrument
panel, and other lamps will not
be on.
Turn the exterior lamp control to
the
; or
5 position for full
illumination when driving at night.
The DRL remain on until the ignition
switch is placed in the OFF position. Hazard Warning Flashers
The hazard warning switch is on the
center stack below the climate
control system.
Press this button to make the front
and rear turn signal lamps flash on
and off. This warns others that you
are having trouble. Press again to
turn the flashers off.
The hazard warning flashers work
with the ignition switch in any
position.
Some localities may prohibit the use
of the hazard warning flashers while
driving.

Driving and Operating 9-252. Pull the parking brake handle up
until you can press the release
button.
3. Hold the release button in as
you move the brake handle all
the way down.
{ CautionDriving 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.
Parking Brake Break-in
Break-in the brake shoes whenever
the effect of the parking brake is
weakened or whenever the brake
shoes and/or drums are replaced, in
order to assure the best brake
performance. This procedure can be
performed at the dealer. Ride Control Systems Traction Control/
Electronic Stability
Control System Operation The vehicle has a Traction Control
System (TCS) and Electronic
Stability Control, an electronic
stability control system. These
systems use various sensors to
monitor driver inputs and vehicle
motion. Under certain driving
conditions, the TCS and Electronic
Stability Control systems help to
perform the following functions: .
Control brake pressure to reduce
wheel slip on one slipping drive
wheel so power is transferred to
a non – slipping drive wheel on
the same axle. .
Control brake pressure and
engine output to reduce drive
wheel slip based on vehicle
speed (traction control function). .
Control brake pressure at
individual wheels and engine
output to help the driver maintain
control of the vehicle in the
following conditions:
‐ Understeer (vehicle tends to
not follow the steered path
despite increased steering
input)
‐ Oversteer (vehicle tends to
spin due to certain road or
driving conditions)
TCS and Electronic Stability Control
can help the driver to maintain
control of the vehicle, but cannot
prevent loss of vehicle control in all
driving situations.
When the TCS and Electronic
Stability Control systems operate,
the
d indicator in the instrument
cluster flashes to note the following: .
The road may be slippery or the
system may determine some
action is required to help keep
the vehicle on the steered path.

Driving and Operating 9-31Warning (Continued) or bent, the sensing zone
may be altered causing
inaccurate measurement of
obstacles or false alarms.
The Rear Parking Assist (RPA)
sounds a tone to warn the driver of
obstacles near the rear bumper
when the shift lever is in
R (Reverse). The system may not
detect objects at speeds above
5 km/h (3 mph) and may not detect
certain angular or moving objects.
The RPA detects objects up to 1.8 m
(5.9 ft) from the rear bumper with a
decreased coverage area at the
outer corners of the bumper. As you
move closer to the obstacle, the rate
of the tone increases. When the
obstacle is less than 25 cm (10 in)
away, the tone will sound
continuously. If the RPA detects a
stationary or receding object further
than 25 cm (10 in) from the side of
the vehicle, the tone will sound for only three seconds. Once the
system detects an object
approaching, the tone will sound
again.
The RPA automatically turns on
when the shift lever is placed in
R (Reverse) and the ignition switch
is in ON. The RPA OFF switch on
the instrument panel allows the
driver to turn the RPA on and off. To
turn the RPA off, the ignition switch
must be placed in ON. An indicator
light on the switch will illuminate
when the system is turned off. If the
indicator light illuminates when the
RPA is not turned off, it may indicate
a malfunction in the RPA.
Keep the RPA sensors, located on
the rear bumper, free from snow,
ice, and large accumulations of dirt.
Do not clean the sensors with sharp
objects. If the sensors are covered,
it will affect the accuracy of
the RPA. Rear Vision
Camera (RVC) When the shift lever is shifted into
R (Reverse), the display shows the
view to the rear of the vehicle.
{ Warning .
Failure to follow the warnings
and instructions for proper
use of the Rear Vision
Camera (RVC) could result in
serious injury or death. .
The RVC is a convenience
but it is not a substitute for
proper backing. Always turn
and look out the windows,
and check mirrors to be sure
that it is safe to move before
operating the vehicle. Always
back up slowly. .
The system is designed as an
aid to the driver in showing
large stationary objects

10-4 Vehicle Care Warning (Continued)Your vehicle ’ s warranty may not
cover damage resulting from
alterations, modifications,
installation of non-approved
accessories, or improper
installation of accessories. Refer
to your Warranty Information
Booklet for complete details.
Variable Voltage Control System
{ Caution .
Do not ground accessories
directly to the battery
terminal. Doing so will bypass
the variable voltage control
system and the vehicle
battery many not charge
completely. .
Use electrical accessories
with the engine running to
avoid discharging the vehicle
battery.
Your vehicle is equipped with a
variable voltage control system.
This system measures the amount
of electrical discharge from the
battery and controls voltage
generated by the generator. The
current sensor is located near the
battery along the negative battery
cable. If you add electrical
accessories to your vehicle, be sure
to ground them to a suitable body
ground such as the frame or engine
block area. Vehicle Checks Doing Your Own
Service Work
{ WarningIt can be dangerous to work on
your vehicle if you do not have
the proper knowledge, service
manual, tools, or parts. Always
follow owner manual procedures
and consult the service manual
for your vehicle before doing any
service work.
If doing some of your own service
work, use the proper service
manual. It tells you much more
about how to service the vehicle
than this manual can. To order the
proper service manual, see Service
Publications Ordering Information
on page 13-11 .

10-36 Vehicle Care the vehicle has not been driven
for at least three hours or no
more than 1.6 km (1 mi).
Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to
get a pressure measurement.
If the cold tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is low,
add air until the recommended
pressure is reached. If the
inflation pressure is high, press
on the metal stem in the center
of the tire valve to release air.
Re-check the tire pressure with
the tire gauge.
Return the valve caps on the
valve stems to prevent leaks
and keep out dirt and moisture. Tire Pressure Monitor
System The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your tires and
transmit tire pressure readings to a
receiver located in the vehicle.
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, you
should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS) that illuminates a low tire pressure telltale when one or more
of your tires is significantly
under-inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them
to the proper pressure. Driving on a
significantly under-inflated tire
causes the tire to overheat and can
lead to tire failure. Under-inflation
also reduces fuel efficiency and tire
tread life, and may affect the
vehicle's handling and stopping
ability.
Please note that the TPMS is not a
substitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correct tire
pressure, even if under-inflation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been
equipped with a TPMS malfunction
indicator to indicate when the
system is not operating properly.

7707496) - 2015 - CRC - 11/26/14
Vehicle Care 10-37The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as
long as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire
pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow the
TPMS to continue to function
properly.
See Tire Pressure Monitor
Operation on page 10-37 . See Radio Frequency Statement on
page 13-12 .
Tire Pressure Monitor
Operation This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn the
driver when a low tire pressure
condition exists. TPMS sensors are
mounted onto each tire and wheel
assembly, excluding the spare tire
and wheel assembly. The TPMS
sensors monitor the air pressure in
the tires and transmit the tire
pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light located on the instrument cluster.
If the warning light comes on, stop
as soon as possible and inflate the
tires to the recommended pressure
shown on the Tire and Loading
Information label. See Vehicle Load
Limits on page 9-9 .
A message displays when the low
tire pressure warning light comes on
and low tire pressure is detected.
See Tire Messages on page 5-20 .
The message and low tire pressure
warning light come on at each
ignition cycle until the tires are
inflated to the correct inflation
pressure. The vehicle must be
driven at speeds above 25 km/h
(16 mph) to activate the TPMS and
turn off the low tire pressure
warning light.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
could be an early indicator that the

7707496) - 2015 - CRC - 11/26/14
10-38 Vehicle Care air pressure is getting low and
needs to be inflated to the proper
pressure.
A Tire and Loading Information label
shows the size of the original
equipment tires and the correct
inflation pressure for the tires when
they are cold. See Vehicle Load
Limits on page 9-9 , for an example
of the Tire and Loading Information
label and its location. Also see Tire
Pressure on page 10-35 .
The TPMS can warn about a low
tire pressure condition but it does
not replace normal tire
maintenance. See Tire Inspection
on page 10-39 , Tire Rotation on
page 10-39 and Tires on
page 10-26 .
{ Caution
Tire sealant materials are not all
the same. A non-approved tire
sealant could damage the TPMS
sensors. TPMS sensor damage
(Continued) Caution (Continued) caused by using an incorrect tire
sealant is not covered by the
vehicle warranty. Always use only
the GM approved tire sealant
available through your dealer or
included in the vehicle.
TPMS Malfunction Light and
Message The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When the
system detects a malfunction, the
low tire pressure warning light
flashes for about one minute and
then stays on for the remainder of
the ignition cycle. The malfunction
light comes on at each ignition cycle
until the problem is corrected. Some
of the conditions that can cause
these to come on are: .
One of the road tires has been
replaced with the spare tire. The
spare tire does not have a TPMS sensor. The malfunction
light should go off after the road
tire is replaced and the sensor
matching process is performed
successfully. See "TPMS Sensor
Matching Process" later in this
section. .
The TPMS sensor matching
process was not done or not
completed successfully after
rotating the tires. The
malfunction light 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
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

Vehicle Care 10-39other than those recommended
could prevent the TPMS from
functioning properly. See Buying
New Tires on page 10-41 ..
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 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
vehicle ’ s tires or replacing one or
more of the TPMS sensors. Also,
the TPMS sensor matching process
should be performed after replacing
a spare tire with a road tire
containing the TPMS sensor. The
malfunction light will go off when the vehicle is driven at speeds above
25 km/h (16 mph) after the next
ignition cycle.
See your dealer to perform the
TPMS sensor matching process.
Tire Inspection We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected
for signs of wear or damage at
least once a month.
Replace the tire if: .
The indicators at three or
more places around the tire
can be seen. .
There is cord or fabric
showing through the tire's
rubber. .
The tread or sidewall is
cracked, cut, or snagged
deep enough to show cord or
fabric. .
The tire has a bump, bulge,
or split. .
The tire has a puncture, cut,
or other damage that cannot
be repaired well because of
the size or location of the
damage.
Tire Rotation Tires should be rotated every
8 000 km (5,000 mi). See
Maintenance Schedule on
page 11-3 .
Tires are rotated to achieve a
uniform wear for all tires. The
first rotation is the most
important.
