If equipped with a locking steering column,
the steering can bind with the front wheels
turned off center, which may prevent key
rotation out of LOCK/OFF. If this happens,
move the steering wheel from right to left
while turning the key to ACC/ACCESSORY.
If this does not work, then the vehicle needs
service.
{Warning
Turning off the vehicle while moving may
cause loss of power assist in the brake
and steering systems and disable the
airbags. While driving, only shut the
vehicle off in an emergency.
In an emergency, if the vehicle cannot be
pulled over and must be turned off while
driving: 1. Push the key all the way in toward the steering column, then turn the key to
ACC/ACCESSORY. 2. Brake using firm and steady pressure. Do
not pump the brakes repeatedly. This
may deplete power assist, requiring
increased brake pedal force.
3. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving.
Continue braking and steer the vehicle to
a safe location.
4. Come to a complete stop. Shift to P (Park) with an automatic transmission,
or Neutral with a manual transmission.
Push the key all the way in toward the
steering column, then turn the ignition

off the vehicle —and turn it only with
your hand.
1. (ACC/ACCESSORY) : This position allows
features such as the infotainment system
to operate while the vehicle is off. It also
unlocks the steering column, if equipped
with a locking steering column. Use this position if the vehicle must be pushed or
towed. See Retained Accessory Power
(RAP). From ON/RUN, push the key all
the way in toward the steering column,
then turn the key to ACC/ACCESSORY.
If the key is left in ACC/ACCESSORY with
the engine off, the battery could drain
and the vehicle may not start. A warning
chime will sound when the driver door is
opened and the key is in the ignition.
2. (ON/RUN) : This position can be used to
operate the electrical accessories and to
display some instrument cluster warning
and indicator lights. This position can
also be used for service and diagnostics,
and to verify the proper operation of the
malfunction indicator lamp as may be
required for emission inspection
purposes. The switch stays in this
position when the engine is running. The
transmission is also unlocked in this
position on automatic transmission
vehicles.
3. (START) : This is the position that starts
the engine. When the engine starts,
release the key. The ignition returns to
ON/RUN for driving.

15 seconds between each try, to allow
the cranking motor to cool down. When
the engine starts, let go of the key and
the accelerator. If the vehicle starts
briefly but then stops again, do the
same thing. This clears the extra gasoline
from the engine.
Do not race the engine immediately
after starting it.
Operate the engine and transmission
gently until the oil warms up and
lubricates all moving parts.
Starting Procedure (Keyless Access)
1. With the Keyless Access system, theremote key must be in the vehicle. Press
ENGINE START/STOPwith the brake pedal
applied. When the engine begins
cranking, let go of the button.
The idle speed will go down as the
engine gets warm. Do not race the
engine immediately after starting it.
If the remote key is not in the vehicle,
if there is interference, or if the remote
key battery is low, a Driver Information
Center (DIC) will display a message. See
Remote Key Operation (Keyless Access)
010 or
Remote Key Operation (Key Access) 015
Caution
Cranking the engine for long periods of
time, by returning the ignition to the
START position immediately after
cranking has ended, can overheat and
damage the cranking motor, and drain
the battery. Wait at least 15 seconds
between each try, to let the cranking
motor cool down.
2. If the engine does not start after five to 10 seconds, especially in very cold
weather (below −18 °C or 0 °F), it could
be flooded with too much gasoline. Try
pushing the accelerator pedal all the way
to the floor and holding it there as you
press ENGINE START/ STOP. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down. When
the engine starts, release the accelerator.
If the vehicle starts briefly but then
stops again, do the same thing. This
clears the extra gasoline from the
engine. Do not race the engine
immediately after starting it. Operate
the engine and transmission gently until
the oil warms up and lubricates all
moving parts.
Stop/Start System
The Stop/Start system shuts off the engine
to help conserve fuel. The system is
designed to manage the increased number
of starts.
{Warning
The automatic engine Stop/Start feature
causes the engine to shut off while the
vehicle is still on. Do not exit the vehicle
before shifting to P (Park). The vehicle
may restart and move unexpectedly.
Always shift to P (Park), and then turn
the ignition off before exiting the vehicle.
Auto Engine Stop/Start
When the brakes are applied and the vehicle
is at a complete stop, the engine may turn
off. When stopped, the tachometer displays
AUTO STOP. See Tachometer088. When
the brake pedal is released or the
accelerator pedal is pressed, the engine will
restart.
To maintain vehicle performance, other
conditions may cause the engine to
automatically restart before the brake pedal
is released.

Driving and Operating 185
Caution
Shifting out of P (Park) or N (Neutral)
with the engine running at high speed
may damage the transmission. The
repairs would not be covered by the
vehicle warranty. Be sure the engine is
not running at high speed when shifting
the vehicle.
Caution
A transmission hot message may display
if the automatic transmission fluid is
too hot.
Driving under this condition can damage
the vehicle. Stop and idle the engine to
cool the automatic transmission fluid.
This message clears when the
transmission fluid has cooled sufficiently.
D : This position is for normal driving.
If more power is needed for passing, press
the accelerator pedal down.
Caution
If the vehicle does not shift gears, the
transmission could be damaged. Have the
vehicle serviced right away.
Caution
Spinning the tires or holding the vehicle
in one place on a hill using only the
accelerator pedal may damage the
transmission.
The repair will not be covered by the
vehicle warranty. If the vehicle is stuck,
do not spin the tires. When stopping on
a hill, use the brakes to hold the vehicle
in place.
L : Allows the driver to select the range of
gear positions. See Manual Mode0185.
Operating Modes
The transmission may operate in a lower
gear than normal to improve vehicle
performance. The engine speed may be
higher and there may be an increase in
noise during the following conditions:
.When climbing a grade.
.When driving downhill.
.When driving in hot temperatures or at
high altitude.
Manual Mode
Electronic Range Select (ERS) Mode
ERS or manual mode allows for the selection
of the range of gear positions. Use this
mode when driving downhill or towing a
trailer to limit the top gear and vehicle
speed. The shift position indicator within the
Driver Information Center (DIC) will display a
number next to the L indicating the highest
available gear under manual mode and the
driving conditions when manual mode was
selected.

Chevrolet TRAX Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17041293) - 2024 - CRC - 12/6/22
186 Driving and Operating
To use this feature:1. Move the shift lever to L (Manual Mode).
2. Press the plus/minus button on the shift lever, to increase or decrease the gear
range available.
When shifting to L (Manual Mode), the
transmission will shift to a preset lower gear
range. For this preset range, the highest
gear available is displayed next to the L in
the DIC. See Driver Information Center (DIC)
(Base Level) 0101 or
Driver Information Center (DIC) (Uplevel)
0 103 for more information. All gears below
that number are available to use. For
example, when 4 (Fourth) is shown next to
the L, 1 (First) through 4 (Fourth) gears are shifted automatically. To shift to 5 (Fifth)
gear, press the + (Plus) button or shift into
D (Drive).
L (Manual Mode) will prevent shifting to a
lower gear range if the engine speed is too
high. If vehicle speed is not reduced within
the time allowed, the lower gear range shift
will not be completed. Slow the vehicle,
then press the
−(Minus) button to the
desired lower gear range.
While using the ERS, cruise control can
be used.
Brakes
Electric Brake Boost
Vehicles equipped with electric brake boost
have hydraulic brake circuits that are
electronically controlled when the brake
pedal is applied during normal operation.
The system performs routine tests and turns
off within a few minutes after the vehicle is
turned off. Noise may be heard during this
time. If the brake pedal is pressed during
the tests or when the electric brake boost
system is off, a noticeable change in pedal
force and travel may be felt. This is normal.
Antilock Brake System (ABS)
The Antilock Brake System (ABS) helps
prevent a braking skid and maintain steering
while braking hard.
ABS performs a system check when the
vehicle is first driven. A momentary motor
or clicking noise may be heard while this
test is going on, and the brake pedal may
move slightly. This is normal.
If there is a problem with ABS, this warning
light stays on. See Antilock Brake System
(ABS) Warning Light 095.
ABS does not change the time needed to
get a foot on the brake pedal and does not
always decrease stopping distance. If you
get too close to the vehicle ahead, there will
not be enough time to apply the brakes if
that vehicle suddenly slows or stops. Always
leave enough room ahead to stop, even
with ABS.

Chevrolet TRAX Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17041293) - 2024 - CRC - 12/6/22
Driving and Operating 187
Using ABS
Do not pump the brakes. Just hold the brake
pedal down firmly. Hearing or feeling ABS
operate is normal.
Braking in Emergencies
ABS allows steering and braking at the same
time. In many emergencies, steering can
help even more than braking.
Electric Parking Brake
The Electric Parking Brake (EPB) can be
applied when the vehicle is on or off.
If there is not enough electrical power, theEPB cannot be applied or released. To
prevent draining the battery, avoid
unnecessary repeated cycles of the EPB.
The EPB status light displays red and the
Service EPB warning light displays amber.
See
Electric Parking Brake Light 095 and
Service Electric Parking Brake Light 095.
There are also EPB-related Driver Information
Center (DIC) messages.
Before leaving the vehicle, look for the red
EPB status light to ensure that the EPB is
applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Pull the EPB switch.
The red EPB status light will flash and then
stay on once the EPB is fully applied. If the
red EPB status light flashes continuously, the
EPB is only partially applied or there is a
problem with the EPB. A DIC message will
display. Release the EPB and try to apply it
again. If the light does not come on,
or continues flashing, have the vehicle
serviced. Do not drive the vehicle if the red
EPB status light is flashing. See your dealer. If the amber Service EPB warning light is on,
pull the EPB switch. Continue to hold the
switch until the red EPB status light remains
on. If the amber Service EPB warning light is
on, see your dealer.
If the EPB is applied while the vehicle is
moving, the vehicle will decelerate as long
as the switch is pulled. If the switch is
pulled until the vehicle comes to a stop, the
EPB will remain applied.
The vehicle may automatically apply the EPB
in some situations when the vehicle is not
moving. This is normal, and is done to
periodically check the correct operation of
the EPB system, or as required by other
safety functions that utilize the EPB.
If the EPB fails to apply, block the rear
wheels to prevent vehicle movement.
EPB Release
To release the EPB:
1. Turn the ignition on or to ACC/ACCESSORY.
2. Apply and hold the brake pedal.
3. Press the EPB switch.
The EPB is released when the red EPB status
light turns off.

Chevrolet TRAX Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17041293) - 2024 - CRC - 12/6/22
188 Driving and Operating
If the amber Service EPB warning light is on,
release the EPB by pressing and holding the
EPB switch. Continue to hold the switch
until the red EPB status light turns off.
If either light stays on after release is
attempted, see your dealer.
Caution
Driving 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.
Automatic EPB Release
The EPB automatically releases if the vehicle
is running, placed into gear, and an attempt
is made to drive. Avoid rapid acceleration
when the EPB is applied to preserve the
parking brake lining life.
Brake Assist
Brake Assist detects rapid brake pedal
applications due to emergency braking
situations and provides additional braking to
activate the Antilock Brake System (ABS) if
the brake pedal is not pushed hard enough
to activate ABS normally. Minor noise, brakepedal pulsation, and/or pedal movement
during this time may occur. Continue to
apply the brake pedal as the driving
situation dictates. Brake Assist disengages
when the brake pedal is released.
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA feature. HSA does
not replace the need to pay attention
and drive safely. You may not hear or
feel alerts or warnings provided by this
system. Failure to use proper care when
driving may result in injury, death,
or vehicle damage. See
Defensive Driving
0 166.
When the vehicle is stopped on a grade, Hill
Start Assist (HSA) temporarily prevents the
vehicle from rolling in an unintended
direction during the transition from brake
pedal release to accelerator pedal apply. The
brakes release when the accelerator pedal is
applied or automatically release after a few
seconds. The brakes may also release under
other conditions. Do not rely on HSA to hold
the vehicle. HSA is available when the vehicle is facing
uphill in a forward gear, or when facing
downhill in R (Reverse). The vehicle must
come to a complete stop on a grade for HSA
to activate.
Ride Control Systems
Traction Control/Electronic
Stability Control
System Operation
The vehicle may have a Traction Control
System (TCS) and StabiliTrak/Electronic
Stability Control (ESC), an electronic stability
control system. These systems help limit
wheel slip and assist the driver in
maintaining control, especially on slippery
road conditions.
TCS activates if it senses that any of the
drive wheels are spinning or beginning to
lose traction. When this happens, TCS
applies the brakes to the spinning wheels
and reduces engine power to limit
wheel spin.
StabiliTrak/ESC activates when the vehicle
senses a difference between the intended
path and the direction the vehicle is actually
traveling. StabiliTrak/ESC selectively applies

Chevrolet TRAX Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17041293) - 2024 - CRC - 12/6/22
Driving and Operating 189
braking pressure to any one of the vehicle
wheel brakes to assist the driver in keeping
the vehicle on the intended path.
If cruise control is being used and traction
control or StabiliTrak/ESC begins to limit
wheel spin, cruise control will disengage.
Cruise control may be turned back on when
road conditions allow.
Both systems come on automatically when
the vehicle is started and begins to move.
The systems may be heard or felt while
they are operating or while performing
diagnostic checks. This is normal and does
not mean there is a problem with the
vehicle.
It is recommended to leave both systems on
for normal driving conditions, but it may be
necessary to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow. SeeIf the
Vehicle Is Stuck 0171 and “Turning the
Systems Off and On” later in this section.The indicator light for both systems is in the
instrument cluster. This light will:
.Flash when TCS is limiting wheel spin.
.Flash when StabiliTrak/ESC is activated.
.Turn on and stay on when either system
is not working.
If either system fails to turn on or to
activate, a message displays in the Driver
Information Center (DIC), and
dcomes on
and stays on to indicate that the system is
inactive and is not assisting the driver in
maintaining control. The vehicle is safe to
drive, but driving should be adjusted
accordingly.
If
dcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.
Drive the vehicle. If
dcomes on and stays
on, the vehicle may need more time to
diagnose the problem. If the condition
persists, see your dealer.

Cruise Control
Cruise control allows the vehicle to maintain
a speed of about 40 km/h (25 mph) or more
without keeping your foot on the
accelerator pedal. Cruise control does not
work at speeds below 40 km/h (25 mph).
{Warning
Cruise control can be dangerous where
you cannot drive safely at a steady
speed. Do not use cruise control on
winding roads or in heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could lose
control. Do not use cruise control on
slippery roads.
If equipped with Adaptive Cruise Control
(ACC), the cruise control system may
automatically brake to slow the vehicle
down to maintain the cruise control set
speed or while navigating a sharp turn.
Cruise control will disengage if:
.The Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control
(ESC) activates to limit wheel spin. See
Traction Control/Electronic Stability
Control 0188.
.TCS or StabiliTrak/ESC is turned off.
.A collision alert occurs. See Forward
Collision Alert (FCA) System 0203.
.The brakes are applied. When road conditions allow you to safely
use it again, cruise control can be turned
back on.
