200 Driving and Operating
Caution
Shifting to R (Reverse) while the vehicle is
moving forward could damage the
transmission. The repairs would not be
covered by the vehicle warranty. Shift to
R (Reverse) only after the vehicle is
stopped.
To rock the vehicle back and forth to get
out of snow, ice, or sand without damaging
the transmission, see If the Vehicle Is Stuck
0 188.
N : In this position, the engine does not
connect with the wheels. To restart the
engine when the vehicle is already moving,
use N (Neutral) only.
{Warning
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is firmly on
the brake pedal, the vehicle could move
very rapidly. You could lose control and
hit people or objects. Do not shift into a
drive gear while the engine is running at
high speed.
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. If the vehicle is stopped on a hill, with your
foot off the brake pedal, the vehicle may
roll. This is normal and is due to the torque
converter designed to improve fuel economy
and performance. Use the brake to hold the
vehicle on a hill. Do not use the accelerator
pedal.
If equipped with the 2.0L L4 engine, engine
speeds may be increased while driving at
highway speeds while the engine is still
warming up.
L :
This position gives you access to gear
ranges. This provides more engine braking
but lower fuel economy than D (Drive). You
can use it on very steep hills, or in deep
snow or mud. See Manual Mode0201.
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

16401961) - 2023 - CRC - 5/17/22
Driving and Operating 201
Manual Mode
Electronic Range Select (ERS) Mode
ERS mode allows you to choose the top-gear
limit of the transmission and the vehicle's
speed while driving downhill or towing a
trailer. The vehicle has an electronic shift
position indicator within the instrument
cluster. When using the ERS mode a number
will display next to the L, indicating the
highest gear available for the range selected.
To use this feature:1. Press the shift lever button and move the shift lever to L (Low). 2. Press + (Plus) or
−(Minus) on the shift
lever to increase or decrease the gear
range available.
When you shift from D (Drive) to L (Low),
the transmission will shift to a
pre-determined lower gear range. The
highest gear available for this
pre-determined range is displayed next to
the L in the DIC. See Driver Information
Center (DIC) (Uplevel) 0112 or
Driver Information Center (DIC) (Base Level)
0 109. The number displayed in the DIC is
the highest gear that the transmission will
be allowed to operate in. This means that
all gears below that number are available.
For example, when 4 (Fourth) is shown next
to the L, 1 (First) through 4 (Fourth) gears
are automatically shifted by the vehicle. The
transmission will not shift into 5 (Fifth) until
the + (Plus) button is used or you shift back
into D (Drive).
If the transmission is in 9 (ninth) gear when
L (low) is selected, a downshift to 7 (seventh)
will be commanded. If in 8 (eighth) through
2 (second), a single downshift will occur.
While in L (Low), the transmission will
prevent shifting to a lower gear range if the
engine speed is too high. You have a brief
period of time to slow the vehicle. If vehicle speed is not reduced within the time
allowed, the lower gear range shift will not
be completed. You must further slow the
vehicle, then press
−(Minus) to the desired
lower gear range.
Automatic Engine Grade Braking is not
available when the ERS is active. It is
available in D (Drive) for both normal driving
and Tow/Haul Mode. While using the ERS,
cruise control and the Tow/Haul Mode can
be used. See “Tow/Haul Mode” underDriver
Mode Control 0206.
Drive Systems
All-Wheel Drive
Vehicles with this feature can operate in
All-Wheel Drive (AWD) Mode.

Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16401961) - 2023 - CRC - 5/17/22
202 Driving and Operating
Turn the knob to4to select AWD.
See Driver Mode Control 0206.
When operated in two-wheel drive, the
vehicle will deliver power to the front
wheels only and may provide better fuel
economy.
When using a compact spare tire on an
AWD vehicle, the system automatically
detects the compact spare and reduces AWD
performance to protect the system. To
restore full AWD operation and prevent
excessive wear on the system, replace the
compact spare with a full-size tire as soon as
possible. See Compact Spare Tire 0301.
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 0104.
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.
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.

16401961) - 2023 - CRC - 5/17/22
Driving and Operating 203
Electric Parking Brake
The Electric Parking Brake (EPB) can always
be applied, even if the vehicle is off. In case
of insufficient electrical power, the EPB
cannot be applied or released. To prevent
draining the battery, avoid unnecessary
repeated cycles of the EPB.
The system has a red parking brake status
light and an amber service parking brake
warning light. SeeElectric Parking Brake
Light 0103 and
Service Electric Parking Brake Light 0103.
There are also parking brake-related Driver
Information Center (DIC) messages. Before leaving the vehicle, check the red
parking brake status light to ensure that the
parking brake is applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Press the EPB switch momentarily.
The red parking brake status light will flash
and then stay on once the EPB is fully
applied. If the red parking brake status light
flashes continuously, then 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 keeps flashing,
have the vehicle serviced. Do not drive the
vehicle if the red parking brake status light
is flashing. See your dealer.
If the amber service parking brake warning
light is on, press the EPB switch. Continue to
hold the switch until the red parking brake
status light remains on. If the amber service
parking brake 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 pressed. If the switch is
pressed 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 at the request of 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 momentarily.
The EPB is released when the red parking
brake status light is off.
If the amber service parking brake warning
light is on, release the EPB by pressing and
holding the EPB switch. Continue to hold the
switch until the red parking brake status
light is off. If either light stays on after
release is attempted, see your dealer.

16401961) - 2023 - CRC - 5/17/22
204 Driving and Operating
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.
If you are towing a trailer and parking on a
hill, see Driving Characteristics and Towing
Tips 0235.
Automatic EPB Release
The EPB will automatically release if the
vehicle is running, placed into gear, and an
attempt is made to drive away. Avoid rapid
acceleration when the EPB is applied, to
preserve 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, brake
pedal 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
0 180.
When the vehicle is stopped on a grade, Hill
Start Assist (HSA) 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. If the
accelerator pedal is not applied within a few
minutes, the Electric Parking Brake will
apply. 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 has a Traction Control System
(TCS) and StabiliTrak/Electronic Stability
Control (ESC). These systems help limit
wheel spin 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. TCS also applies torque to the
non-spinning wheel to increase traction and
acceleration.
StabiliTrak/ESC activates when the vehicle
senses a difference between the intended
path and the direction the vehicle is actually

Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16401961) - 2023 - CRC - 5/17/22
Driving and Operating 205
traveling. StabiliTrak/ESC selectively applies
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 TCS or
StabiliTrak/ESC begins to limit wheel spin,
cruise control will disengage. Cruise control
may be turned back on when road
conditions allow. TCS and StabiliTrak/ESC will
automatically turn on when cruise control
is set.
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 0188 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 may display in the
Driver Information Center (DIC), and
d
comes 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.
4. 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.

If equipped, the Driver Mode Control has the
following Modes: Tour (FWD), Sport,
All-Wheel Drive (AWD), Snow, Tow/Haul, and
Off-Road. Rotate the Driver Mode Control
knob on the center console to make a mode
selection. Continue turning the knob through
the available modes. The selected mode’s
icon will light up on the knob.
If the vehicle is in Tour (FWD) or AWD, it
will stay in that mode through future ON/
OFF cycles. If the vehicle is in any other
mode, it will revert back to Tour (FWD)
when the vehicle is restarted.
Driver Mode Control Knob
5orqTour : Vehicle is in Tour (FWD)
mode. Use this mode during normal driving
conditions. See Driving for Better Fuel
Economy 0179. Tour (FWD) mode operates
in Front-Wheel Drive to improve fuel
economy.
8Sport : Sport mode improves vehicle
handling and acceleration on dry pavement.
When active, Sport mode modifies steering
efforts, transmission shifting, AWD torque,
suspension tuning (when equipped), and
StabiliTrak/Electronic Stability Control (ESC)
settings. For vehicles equipped with AWD,
choosing Sport mode also engages AWD.
4AWD (AWD Only) : AWD mode
provides drive torque to all four wheels.
Select AWD to improve traction and control
on slippery road surfaces, such as gravel,
sand, wet pavement, snow, and ice. When in
AWD mode, the AWD mode indicator will

Driving and Operating 207
_Tow/Haul :This feature can assist
when towing a heavy load. Use this mode
to assist in maintaining desired vehicle
speeds when driving on downhill grades by
using the engine and transmission. When
active, Tow/Haul mode modifies
transmission shifting, suspension tuning,
steering effort, and Trailer Sway Control. For
AWD vehicles, choosing Tow/Haul mode also
engages AWD. See Driving Characteristics
and Towing Tips 0235.
Automatic Engine Grade Braking
Automatic Engine Grade Braking assists
when driving downhill. It maintains vehicle
speed by automatically implementing a shift
pattern that uses the engine and the
transmission to slow the vehicle. The system
will automatically command downshifts to
reduce vehicle speed. The normal shift
pattern will return once the vehicle is on a
low grade or when the accelerator pedal is
pressed.
While in the Electronic Range Select (ERS)
mode, grade braking is deactivated, allowing
the driver to select a range and limiting the
highest gear available. Grade braking is
available for normal driving and in Tow/
Haul mode. See
Automatic Transmission 0199.
7Off-Road (AWD Only) : Use this mode
for off-road recreational driving. When
active, Off-Road mode modifies accelerator
pedal response, ABS, TCS, and the
StabiliTrak/ESC system. Choosing Off-Road
mode also engages AWD. For more
information on Off-Road mode, see Off-Road
Driving 0182.
Cruise Control
{
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. With cruise control, a speed of about
40 km/h (25 mph) or more can be
maintained without keeping your foot on
the accelerator. Cruise control does not work
at speeds below about 40 km/h (25 mph).
If the Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control (ESC)
system begins to limit wheel spin while
using cruise control, the cruise control
automatically disengages. See
Traction
Control/Electronic Stability Control 0204.
If a collision alert occurs when cruise control
is activated, cruise control is disengaged. See
Forward Collision Alert (FCA) System 0223.
When road conditions allow the cruise
control to be safely used, cruise control can
be turned back on.
Turning off the TCS or StabiliTrak/ESC
system will disengage the cruise control.
If the brakes are applied, cruise control
disengages.

indicator appears on the instrument cluster.
Resuming a Set Speed
If the cruise control is set at a desired speed
and then the brakes are applied or
*is
pressed, the cruise control is disengaged
without erasing the set speed from memory.
Once the vehicle speed reaches about
40 km/h (25 mph) or more, move the
thumbwheel up toward RES+ briefly. The
vehicle returns to the previous set speed. Increasing Speed While Using Cruise Control
If the cruise control system is already
activated:
.Move the thumbwheel up toward RES+
until the desired speed is reached, then
release it.
.To increase vehicle speed in small
increments, move the thumbwheel up
toward RES+ briefly. For each press, the
vehicle goes about 1 km/h (1 mph) faster.
The speedometer reading can be displayed
in either English or metric units. See
Instrument Cluster (Uplevel) 094 or
Instrument Cluster (Base Level) 092. The
increment value used depends on the units
displayed.
Reducing Speed While Using Cruise Control
If the cruise control system is already
activated:
.Move the thumbwheel down toward SET−
until the desired lower speed is reached,
then release it.
.To decrease the vehicle speed in small
increments, move the thumbwheel down
toward SET− briefly. For each press, the
vehicle goes about 1 km/h (1 mph) slower.

Passing Another Vehicle While Using Cruise
Control
Use the accelerator pedal to increase the
vehicle speed. When you take your foot off
the pedal, the vehicle will slow down to the
previous set cruise speed.
While pressing the accelerator pedal or
shortly following the release to override
cruise, briefly moving the thumbwheel down
toward SET− will result in cruise set to the
current vehicle speed.
Using Cruise Control on Hills
How well the cruise control will work on
hills depends upon the vehicle speed, load,
and the steepness of the hills. When going
up steep hills, you might have to step on
the accelerator pedal to maintain your
speed. When going downhill, you might
have to brake or shift to a lower gear to
keep your speed down. If the brake pedal is
applied, cruise control disengages. Ending Cruise Control
There are four ways to end cruise control:
.Step lightly on the brake pedal.
.Press*.
.Shift the transmission to N (Neutral).
.PressJ.
Erasing Speed Memory
The cruise control set speed is erased from
memory if
Jis pressed or if the ignition is
turned off.
Adaptive Cruise Control
(Advanced)
If equipped, Adaptive Cruise Control (ACC)
allows the cruise control set speed and
following gap to be selected. Read this
entire section before using this system. The
following gap is the following time between
your vehicle and a vehicle detected directly
ahead in your path, moving in the same
direction. If no vehicle is detected in your
path, ACC works like regular cruise control.
ACC uses camera and radar sensors. See
Radio Frequency Statement 0337.
If a vehicle is detected in your path, ACC can
apply acceleration or limited, moderate
braking to maintain the selected following gap. To disengage ACC, apply the brake
pedal. If ACC is controlling your vehicle
speed when the Traction Control System
(TCS) or StabiliTrak/Electronic Stability
Control (ESC) system activates, the ACC may
automatically disengage. See
Traction
Control/Electronic Stability Control 0204.
When road conditions allow ACC to be
safely used, the ACC can be turned back on.
Turning off the TCS or StabiliTrak/ESC
system will disengage the cruise control.
ACC can reduce the need for you to
frequently brake and accelerate, especially
when used on expressways, freeways, and
interstate highways. When used on other
roads, you may need to take over the
control of braking or acceleration more
often.
{Warning
ACC has limited braking ability and may
not have time to slow the vehicle down
enough to avoid a collision with another
vehicle you are following. This can occur
when vehicles suddenly slow or stop
ahead, or enter your lane. Also see
“Alerting the Driver” in this section.
