158 Driving and Operating
Rear Cross Traffic Alert (RCTA)
On vehicles with RCTA, a triangle with an
arrow may display on the infotainment
display to warn of traffic coming from either
direction. This system detects objects
coming from up to 20 m (65 ft) from the left
or right side, behind the vehicle. When an
object is detected, three beeps sound from
the left or right side, depending on the
direction of the detected vehicle.
The Park Assist and RCTA symbols appear
and may cover an object when viewing the
infotainment display when an object is
detected by the RPA or RCTA system. To
turn the symbols on or off, seeVehicle
Personalization 093.
RCTA can be turned on or off through
vehicle personalization. See “Collision
Detection Systems” underVehicle
Personalization 093.
Park Assist
If equipped, Rear Park Assist (RPA) system, it
assists you with parking and avoiding
objects while in R (Reverse). RPA operates at
speeds less than 8 km/h (5 mph), and the
sensors on the rear bumper detect objects
up to 1.5 m (5 ft) behind the vehicle, and at least 30 cm (12 in) off the ground. The
distance objects can be detected may be
less during warmer or humid weather.
{Warning
The Park Assist system does not detect
children, pedestrians, bicyclists, animals,
or objects below the bumper or that are
too close or too far from the vehicle. It is
not available at speeds greater than
8 km/h (5 mph). To prevent injury, death,
or vehicle damage, even with Park Assist,
always check the area around the vehicle
and check all mirrors before backing.
How the System Works
RPA comes on automatically when the shift
lever is moved into R (Reverse).
An obstacle is indicated by audible beeps.
The interval between the beeps becomes
shorter as the vehicle gets closer to the
obstacle. When the distance is less than
30 cm (12 in) the beeping is a continuous
tone for five seconds.
Turning the System On and Off
The RPA system can be turned on and off
using the infotainment system controls. See
Vehicle Personalization
093.
When the System Does Not Seem to
Work Properly
This light may come on for the following
reasons:
.The sensors are not clean. Keep the
vehicle's rear bumper free of mud, dirt,
snow, ice, and slush. For cleaning
instructions, see Exterior Care0226.
.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
light may not clear until the frost or ice
has melted.

208 Vehicle Care
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, defined above, flashes for about
one minute and then stays on for the
remainder of the ignition cycle. A DIC
warning message may also display. The
malfunction light and DIC warning message,
if equipped, 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 the DIC message, if equipped,
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, if equipped,
should go off after successfullycompleting 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, if equipped, 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 0211.
.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,
if equipped, come on and stay 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 and the DIC
message, if equipped, 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.
