Lighting 97
This indicator light turns on in the
instrument cluster when the high-beam
headlamps are on.
Flash-to-Pass
To flash the high beams, pull the turn signal
lever all the way toward you. Then
release it.
Daytime Running Lamps (DRL)
Daytime Running Lamps can make it easier
for others to see the front of your vehicle
during the day. Fully functional DRL are
required on all vehicles first sold in Canada.
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 on.
.The exterior lamp control is in AUTO.
.The engine is running.
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. The headlamps automatically change from
DRL to the regular headlamps depending on
the darkness of the surroundings. The other
lamps that come on with the headlamps will
also come on.
When it is bright enough outside, the
headlamps go off and the DRL come on.
To turn the DRL off or on again, turn the
exterior lamp control to the off position and
then release. For vehicles first sold in
Canada, the DRL can only be turned off
when the vehicle is parked.
Automatic Headlamp System
If equipped, the headlamps come on
automatically when it is dark enough
outside and the exterior lamp control is in
the automatic position. See
Exterior Lamp
Controls 096.
The vehicle has a light sensor on top of the
instrument panel. Make sure it is not
covered, or the headlamps will be on when
they are not needed.
The system may also turn on the headlamps
when driving through a parking garage or
tunnel.
Lights On with Wipers
If the windshield wipers are activated in
daylight with the engine on, and the
exterior lamp control is in AUTO, the
headlamps, parking lamps, and other
exterior lamps come on. The transition time
for the lamps coming on varies based on
wiper speed. When the wipers are not

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.

.An object was hanging out of the liftgate
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 the above conditions do not exist, take
the vehicle to your dealer to repair the
system.
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 spot)
areas. The SBZA warning display will light
up in the corresponding outside side mirror
and will flash if the turn signal is on.
{Warning
SBZA does not alert the driver to vehicles
rapidly approaching outside of the side
blind zones, pedestrians, bicyclists, (Continued)
Warning (Continued)
or animals. It may not provide alerts
when changing lanes under all driving
conditions. Failure to use proper care
when changing lanes may result in injury,
death, or vehicle damage. Before making
a lane change, always check mirrors,
glance over your shoulder, and use the
turn signals.
SBZA Detection Zones
The SBZA sensor covers a zone of
approximately one lane over from both
sides of the vehicle, or 3.5 m (11 ft). The
height of the zone is approximately between 0.5 m (1.5 ft) and 2 m (6 ft) off the ground.
This zone starts at approximately the middle
of the vehicle and goes back 5 m (16 ft).
How the System Works
The SBZA symbol lights up in the side
mirrors when the system detects a moving
vehicle in the next lane over that is in the
side blind zone. This indicates it may be
unsafe to change lanes. Before making a
lane change, check the SBZA display, check
mirrors, glance over your shoulder, and use
the turn signals.
Left Side Mirror
DisplayRight Side Mirror Display
When the vehicle is started, both outside
mirror SBZA displays will briefly come on to
indicate the system is operating. 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 in the

same direction of a detected vehicle, this
display will flash as an extra warning not to
change lanes.
SBZA can be disabled through vehicle
personalization. See“Collision/Detection
Systems” underVehicle Personalization 093.
If SBZA is disabled by the driver, the SBZA
mirror displays will not light up.
When the System Does Not Seem to
Work Properly
SBZA displays may not come on when
passing a vehicle quickly or for a stopped
vehicle. SBZA may alert to objects attached
to the vehicle, such as a bicycle, or object
extending out to either side of the vehicle.
This is normal system operation; the vehicle
does not need service.
SBZA may not always alert the driver to
vehicles in the side blind zone, especially in
wet conditions. The system does not need
to be serviced. The system may light up due
to guardrails, signs, trees, shrubs, and other
non-moving objects. This is normal system
operation; the vehicle does not need service.
SBZA may not operate when the SBZA
sensors in the left or right corners of the
rear bumper are covered with mud, dirt,
snow, ice, or slush, or in heavy rainstorms. For cleaning instructions, see "Washing the
Vehicle" under
Exterior Care0226. If the DIC
still displays the system unavailable
message after cleaning both sides of the
vehicle toward the rear corners of the
vehicle, see your dealer.
If the SBZA displays do not light up when
vehicles are in the blind zone and the
system is clean, the system may need
service. Take the vehicle to your dealer.
When SBZA is disabled for any reason other
than the driver turning it off, the Side Blind
Zone Alert On option will not be available
on the personalization menu.

206 Vehicle Care
How to Check
Use a good quality pocket-type gauge
to check tire pressure. Proper tire
inflation cannot be determined by
looking at the tire. Check the tire
inflation pressure when the tires are
cold, meaning 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.
Recheck the tire pressure with the tire
gauge.Put the valve caps back on the valve
stems to keep out dirt and moisture.
Use only valve caps designed for the
vehicle by GM. TPMS sensors could be
damaged and would not be covered by
the vehicle warranty.
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. The
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

Chevrolet TRAX Owner Manual (GMNA-Localizing-U.S./Canada-14609828) -
2021 - CRC - 8/21/20
Vehicle Care 207
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.
SeeTire Pressure Monitor Operation 0207.
See Radio Frequency Statement 0257.
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
0 134.
A message to check the pressure in a
specific tire may display in the Driver
Information Center (DIC). The low tire
pressure warning light and the DIC warning
message, if equipped, come on at each
ignition cycle until the tires are inflated to
the correct inflation pressure. Using the DIC,
it may be possible to view the tire pressure
levels. For additional information and details
about the DIC operation and displays, see
Driver Information Center (DIC) 090. 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 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
0 134, for an example of the Tire and
Loading Information label and its location.
Also see Tire Pressure 0205.
The TPMS can warn about a low tire
pressure condition, but it does not replace
normal tire maintenance. See Tire Inspection
0 209, Tire Rotation 0209, and Tires0199.
Caution
Tire sealant materials are not all the
same. A non-approved tire sealant could
damage the TPMS sensors. TPMS sensor
damage 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.

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.
