front are higher pitched than
beeps for the rear. If equipped
with Safety Alert seat, both
sides of the seat will pulse
alongside the beeps.
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 Care0457.
.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 PA
system does not activate due
to a temporary condition, the
appropriate message displays
on the DIC. PA OFF message
is displayed when disabled by
the driver. Front/Rear PA OFF
message is displayed when an
attached object is detected in
the front or rear respectively.
PA Temporarily Unavailable
message is displayed for
system failures. This can occur
under the following conditions:
.The driver has disabled the
system.
.An object was hanging out
of the trunk during the last
drive cycle. Once the object
is removed, RPA will return
to normal operation.
.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.

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. To view
available settings for this
feature, touch the Settings
icon on the infotainment home
page. Select
“Vehicle”to
display the list of available
options and select “Collision/
Detection Systems”.{Warning
Using the FPB 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.
Side Blind Zone
Alert (SBZA)
If equipped, the SBZA system
is a lane-changing aid that
assists drivers with avoiding
crashes that occur with
moving vehicles in the side
blind zone, or blind spot areas.
When the vehicle is in a
forward gear, the left or right
side mirror display will light up
if a moving vehicle is detected
in that blind zone. If the turn
signal is activated and a
vehicle is also detected on the
same side, the display will flash
as an extra warning not to
change lanes. Since this
system is part of the Lane
Change Alert (LCA) system,
read the entire LCA section
before using this feature.
Lane Change
Alert (LCA)
If equipped, the LCA system is
a lane-changing aid that
assists drivers with avoiding
lane change crashes that

and the trailer brakes may not
function, which could result in
a crash.
Turn Signals When
Towing a Trailer
When properly connected, the
trailer turn signals will
illuminate to indicate the
vehicle is turning, changing
lanes, or stopping. When
towing a trailer, the arrows on
the instrument cluster will
illuminate even if the trailer is
not properly connected or the
bulbs are burned out.
Conversions and
Add-Ons
Add-On Electrical
Equipment
{Warning
The Data Link Connector
(DLC) is used for vehicle
service and Emission
Inspection/Maintenance
testing. See Malfunction
Indicator Lamp (Check
Engine Light)0125. A device
connected to the DLC —
such as an aftermarket fleet
or driver-behavior tracking
device —may interfere with
vehicle systems. This could
affect vehicle operation and
cause a crash. Such devices
may also access information
stored in the vehicle’s
systems.
Caution
Some electrical equipment
can damage the vehicle or
cause components to not
work and would not be
covered by the vehicle
warranty. Always check with
your dealer before adding
electrical equipment.
Add-on equipment can drain
the vehicle's 12-volt battery,
even if the vehicle is not
operating.
The vehicle has an airbag
system. Before attempting to
add anything electrical to the
vehicle, see Servicing the
Airbag-Equipped Vehicle 077
and
Adding Equipment to the
Airbag-Equipped Vehicle 077.

Do not top off the brake/
clutch fluid. Adding fluid does
not correct a leak. If fluid is
added when the linings are
worn, there will be too much
fluid when new brake linings
are installed. Add or remove
fluid, as necessary, only when
work is done on the brake/
clutch hydraulic system.
{Warning
If too much brake fluid is
added, it can spill on the
engine and burn, if the
engine is hot enough. You or
others could be burned, and
the vehicle could be
damaged. Add brake fluid
only when work is done on
the brake/clutch hydraulic
system.
When the brake/clutch fluid
falls to a low level, the brake
warning light comes on. See
Brake System Warning Light
0 127. Brake fluid absorbs water over
time which degrades the
effectiveness of the brake
fluid. Replace brake fluid at the
specified intervals to prevent
increased stopping distance.
See Maintenance Schedule
0
471.
What to Add
Use only GM approved DOT 4
brake fluid from a clean, sealed
container. See Recommended
Fluids and Lubricants 0476.
{Warning
The wrong or contaminated
brake fluid could result in
damage to the brake
system. This could result in
the loss of braking leading to
a possible injury. Always use
the proper GM approved
brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces,
the paint finish can be
damaged. Immediately wash
off any painted surface.
Battery - North
America
The original equipment battery
is maintenance free. Do not
remove the cap and do not
add fluid.
Refer to the replacement
number shown on the original
battery label when a new
battery is needed.
The vehicle has an Absorbed
Glass Mat (AGM) 12-volt
battery. Installation of a
standard 12-volt battery will
result in reduced 12-volt
battery life.
When using a 12-volt battery
charger on the 12-volt AGM
battery, some chargers have
an AGM battery setting on the

tire pressure warning light
flashes for about one minute
and then stays on for the
remainder of the ignition cycle.
A DIC warning message also
displays. The malfunction light
and DIC warning message
come 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
and DIC message 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 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
malfunction light and the DIC
message 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. See
Buying New Tires
0437.
.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 pressure
condition. See your dealer for
service if the TPMS
malfunction light and DIC
message come on and stay on.
Tire Fill Alert (If Equipped)
This feature provides visual
and audible alerts outside the
vehicle to help when inflating
an underinflated tire to the
recommended cold tire
pressure.
When the low tire pressure
warning light comes on:
1. Park the vehicle in a safe, level place.
2. Set the parking brake firmly.
3. Place the vehicle in P (Park).
4. Add air to the tire that is underinflated. The turn
signal lamp will flash.
