228 Driving and Operating
Warning (Continued)
Always be ready to manually accelerate
or brake to complete the pass or lane
change.
Stationary or Very Slow-Moving Objects
{Warning
ACC may not detect and react to stopped
or slow-moving vehicles ahead of you. For
example, the system may not brake for a
vehicle it has never detected moving. This
can occur in stop-and-go traffic or when a
vehicle suddenly appears due to a vehicle
ahead changing lanes. Your vehicle may
not stop and could cause a crash. Use
caution when using ACC. Your complete
attention is always required while driving
and you should be ready to take action
and apply the brakes.
Irregular Objects Affecting ACC
ACC may have difficulty detecting the
following objects:
.Vehicles with cargo extending from the
back end.
.Non-standard shaped vehicles, such as
vehicle transport, vehicles with a side car
fitted, or horse carriages.
.Objects that are close to the front of your
vehicle.
ACC Automatically Disengages
ACC may automatically disengage and the
driver will need to manually apply the
brakes to slow the vehicle when:
.The sensors are blocked.
.The Traction Control System (TCS) or
StabiliTrak/ESC system has activated or
been disabled.
.There is a fault in the system.
.The radar may falsely report a blockage
when driving in a desert or remote area
with no other vehicles or roadside objects.
.A DIC message may display to indicate
that ACC is temporarily unavailable.
The ACC indicator will turn white when ACC
is no longer active.
In some cases, when ACC is temporarily
unavailable, regular cruise control may be
used. See “Switching Between ACC and
Regular Cruise Control” in this section.
Always consider driving conditions before
using either cruise control system. Notification to Resume ACC
ACC will maintain a follow gap behind a
detected vehicle and slow your vehicle to a
stop behind that vehicle.
If the stopped vehicle ahead has driven
away and ACC has not resumed, the vehicle
ahead indicator will flash as a reminder to
check traffic ahead before proceeding. In
addition, the left and right sides of the
Safety Alert Seat will pulse three times,
or three beeps will sound. Touch the
Settings icon on the infotainment home
page. Select
“Vehicle”to display the list of
available options and select ”Alert Type”and
“Adaptive Cruise Go Notifier” in“Collision/
Detection Systems”.
When the vehicle ahead drives away, ACC
resumes automatically if the stop was brief.
Press RES+ or the accelerator pedal to
resume cruise control. If stopped for more
than two minutes or if the driver door is
opened and the driver seat belt is
unbuckled, the ACC automatically applies the
Electric Parking Brake (EPB) to hold the
vehicle. The EPB status light will turn on.
See Electric Parking Brake 0216. To resume
ACC and release the EPB, press the
accelerator pedal.

{Warning
Use Hitch Guidance only to help back the
vehicle to a trailer hitch or, when
traveling above 12 km/h (8 mph), to
briefly check the status of your trailer. Do
not use for any other purpose, such as
making lane change decisions. Before
making a lane change, always check the
mirrors and glance over your shoulder.
Improper use could result in serious
injury to you or others.
Park Assist
The vehicle may be equipped with Front and
Rear Park Assist (FRPA). Under certain
conditions, the Park Assist system can assist
the driver during backing and parking
maneuvers when the vehicle is driven at no
more than 9 km/h (6 mph). An illuminated
indicator in the Park Assist button indicates
the system is ready.Sensors located in the bumpers measure the
distance between the vehicle and objects
using sonar technology. These sensors are
designed to detect certain objects up to
2.5 m (8 ft) behind and 1.2 m (4 ft) in front of
your vehicle that are taller than
25 cm (10 in).
Different environmental conditions may
affect whether and how far the Park Assist
system can detect objects. Keep the sensors
clean of mud, dirt, snow, ice, and slush; and
clean sensors after a car wash in freezing
temperatures. Sensors that are not clean
may not detect objects or may cause the
system to alert when not required.
{Warning
The Park Assist System is no substitute
for careful and attentive driving. The Park
Assist system does not detect children,
pedestrians, bicyclists, animals, or objects
located below the bumper or that are too
close or too far from the vehicle. It is not
available at speeds greater than 9 km/h
(6 mph). To prevent injury, death,
or vehicle damage, even with Park Assist,

Factory-installed Tire Inflator Kits use a
GM-approved liquid tire sealant. Using
non-approved tire sealants could damage the
TPMS sensors. SeeTire Sealant and
Compressor Kit 0312 for information
regarding the inflator kit materials and
instructions.
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. 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 0307.
.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.
When the recommended pressure is
reached, the horn sounds once and the
turn signal lamp will stop flashing and
briefly turn solid.
Repeat these steps for all underinflated tires
that have illuminated the low tire pressure
warning light.
{Warning
Overinflating a tire could cause the tire
to rupture and you or others could be
injured. Do not exceed the maximum (Continued)

pressure listed on the tire sidewall. See
Tire Sidewall Labeling0294 and
Vehicle Load Limits 0200.
If the tire is overinflated by more than
35 kPa (5 psi), the horn will sound multiple
times and the turn signal lamp will continue
to flash for several seconds after filling
stops. To release and correct the pressure,
while the turn signal lamp is still flashing,
briefly press the center of the valve stem.
When the recommended pressure is reached,
the horn sounds once.
If the turn signal lamp does not flash within
15 seconds after starting to inflate the tire,
the tire fill alert has not been activated or is
not working.
If the hazard warning flashers are on, the
tire fill alert visual feedback will not work
properly.
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 0204.
3. Make sure the Tire Pressure info page option is turned on. The info pages on
the DIC can be turned on and off
through the Options menu. See Driver
Information Center (DIC) (Base Level)
0 114 orDriver Information Center (DIC)
(Midlevel) 0116 orDriver Information
Center (DIC) (Uplevel) 0119.
4. Use the DIC controls on the right side of the steering wheel to scroll to the Tire
Pressure screen under the DIC info page.
5. Press and hold
Vin the center of the
DIC controls.
