Driving and Operating 207
R :Use this gear to back up.
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
0 195.
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.
Powertrain Braking
When driving on steep descents with the
shift lever in D (Drive) where frequent
braking is required, the transmission will
shift down a gear to help hold vehicle speed and reduce brake wear. If the brake
continues to be pressed, the transmission
will downshift until the correct gear for
optimal braking is reached.
If the road levels out and the accelerator
pedal is pressed, the transmission will
upshift until the appropriate gear is reached.
Caution
If the vehicle does not shift gears, the
transmission could be damaged. Have the
vehicle serviced right away.
Performance Shifting
While driving in Sport Mode (L4, if equipped
or V6, if equipped), or Sport Mode and Track
Mode (V8, if equipped), if Tap Shift has not
been activated, the transmission determines
when the vehicle is being driven in a
competitive manner. The transmission may
remain in a gear longer than it would in the
normal driving mode based on throttle input
and vehicle lateral acceleration. If there is a
rapid reduction in throttle from a heavy
throttle position at high rpm, the
transmission will maintain the current gear
up to near redline rpm. While braking, the
transmission will automatically downshift to
the next lower gear keeping engine speed

Chevrolet Camaro Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14583589) - 2021 - CRC - 10/1/20
208 Driving and Operating
above approximately 3000 rpm. If the
vehicle is then driven for a short time at a
steady speed, and without high cornering
loads, the transmission will upshift one gear
at a time until the highest available gear is
reached. After shifting to the highest
available gear, the transmission will return
to normal Sport Mode shifting.
Manual Mode
Driver Shift Control (DSC)Caution
Driving with the engine at a high rpm
without upshifting while using Driver
Shift Control (DSC), could damage the
vehicle. Always upshift when necessary
while using DSC.
DSC allows shifting an automatic
transmission similar to a manual
transmission. To use the DSC feature:1. Move the shift lever to the left from D (Drive) into the side gate marked
with +/−.
2. Press the shift lever forward to upshift or rearward to downshift.
While using the DSC feature, the vehicle will
have firmer, quicker shifting. You can use
this for sport driving or when climbing or
descending hills, to stay in gear longer,
or to downshift for more power or engine
braking. The transmission will only allow you to shift
into gears appropriate for the vehicle speed
and engine revolutions per minute (rpm).
The transmission will not automatically shift
to the next lower gear if the engine rpm is
too high, nor to the next higher gear when
the maximum engine rpm is reached.
While in the DSC mode, the transmission
will automatically downshift as the vehicle
comes to a stop. This will allow for more
power during take-off.Tap Shift
Tap Shift allows you to manually control the
automatic transmission. To use Tap Shift,
the shift lever must be in DSC mode.
Vehicles with this feature have indicators on

14583589) - 2021 - CRC - 10/1/20
Driving and Operating 209
the steering wheel. The paddles are on the
back of the steering wheel. Tap the left
paddle (−) to downshift, and the right
paddle (+) to upshift. The Driver Information
Center (DIC) display indicates the gear the
vehicle is in.
Holding the left paddle for an extended time
will downshift the transmission to the
lowest available gear.
While in Manual Mode, the transmission will
prevent shifting to a lower gear if the
engine speed is too high. If the tap down
−(Minus) paddle is held while the vehicle
slows down, the M in the DIC will flash, and
the downshift will be allowed when vehicle
speed is low enough. Continuing to hold the
tap down −(Minus) paddle will not cause
the transmission to continue downshifting.
Each downshift must be requested
separately by releasing and reapplying the
tap down −(Minus) paddle.
Head-Up Display (HUD)
Vehicles equipped with a Head-Up Display
(HUD) may also have performance shift
timing lights across the top of the display. The rows of lights get closer together as the
maximum shift point gets closer. Shift the
transmission before the lights come together
in the display. Shift immediately if the lights
are flashing.
See
Head-Up Display (HUD) 0100.
Temporary Tap Shift Mode allows brief
entry into Tap Shift Mode while in D (Drive).
Tapping either the upshift or downshift
control will place the transmission in Tap
Shift Mode. Exit Tap Shift Mode by holding
the upshift control for two seconds. The
system will return to automatic shifting
after seven seconds of driving at a steady
speed, or when the vehicle comes to a stop.
This may be used for sport driving or when
climbing or descending hills, to stay in gear
longer, or to downshift for more power or
engine braking. The transmission will only
allow you to shift into gears appropriate for
the vehicle speed and engine revolutions per
minute (rpm). The transmission will not
automatically shift to the next higher gear if
the engine rpm is too high. If shifting is
prevented for any reason, the gear displayed
in the DIC will blink several times, indicating
that the transmission has not shifted gears. While in the Tap Shift Mode, the
transmission will not automatically
downshift on hard acceleration.

4 (Fourth) instead of 1 (First) to 2 (Second).
The message will display in the Driver
Information Center (DIC).
Complete the shift into 4 (Fourth) to turn off
this feature. This helps to get the best
possible fuel economy.
After shifting to 4 (Fourth), downshift to a
lower gear, if desired.
Caution
Forcing the shift lever into any gear
except 4 (Fourth) when the 1-4 SHIFT
message comes on may damage the
transmission. Shift only from 1 (First) to
4 (Fourth) when the message comes on.
This message will come on when:
.The engine coolant temperature is higher
than 76 °C (169 °F).
.The vehicle is accelerating from a stop
and going 24 to 31 km/h (15 to 19 mph).
.The vehicle is at 33% throttle or less.
Once displayed, the message will remain in
the DIC for two seconds, even if the
conditions for skip shift are no longer
satisfied. Vehicles equipped with a Head-Up Display
(HUD) may also have performance shift
timing lights across the top of the display.
The rows of lights get closer together as the
maximum shift point gets closer. Shift the
transmission before the lights come together
in the display. Shift immediately if the lights
are flashing.
See
Head-Up Display (HUD) 0100.
Active Rev Match
Vehicles equipped with a V8 engine and a
manual transmission have Active Rev Match
(ARM). ARM aids in smoother shifting by
matching the engine speed to the next
selected gear. By monitoring shift lever and
clutch operation, ARM adjusts engine speed
to match a calibrated value based on gear
selection. On upshifts and downshifts,
engine speed will be decreased and
increased to match vehicle road speed and
transmission gear position. ARM is
maintained while the clutch pedal is pressed,
but will deactivate if the shift lever is left in
the Neutral position.

Chevrolet Camaro Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14583589) - 2021 - CRC - 10/1/20
212 Driving and Operating
The system is activated and deactivated by
pressing either of the paddles marked REV
MATCH on the steering wheel. The system
must be activated with each new ignition
cycle.
A gear indicator in the instrument cluster
displays the current gear selected:
.When ARM is activated, the gear number
is amber.
.When ARM is deactivated, the gear
number is white.
.If no gear number is displayed while the
shift lever is in gear, service is required.
ARM will be disabled, and the malfunctionindicator lamp will be on. See
Malfunction
Indicator Lamp 091. The clutch and
manual transmission will continue to
operate normally.
ARM will also:
.Only be active above 25 km/h (16 mph).
.Only match engine speed up to
5400 rpm.
.Not operate when the accelerator pedal is
applied.
.Be disabled when the coolant
temperature is below 0 °C (32 °F).
Brakes
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 094.
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.

Chevrolet Camaro Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14583589) - 2021 - CRC - 10/1/20
214 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.
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.
The EPB can also be used to prevent roll
back for vehicles with a manual transmission
taking off on a hill. When no roll back is
desired, an applied EPB will allow both feet
to be used for the clutch and accelerator
pedals in preparation for starting the vehicle
moving in the intended direction. In this
case, there is no need to press the switch to
release the EPB.]
Brake Assist
Brake Assist detects rapid brake pedal
applications due to emergency braking
situations and provides additional braking toactivate 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
0 182.
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 has a Traction Control System
(TCS) and StabiliTrak/Electronic Stability
Control (ESC). 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.

Chevrolet Camaro Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14583589) - 2021 - CRC - 10/1/20
Driving and Operating 215
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
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 0195 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.

Adding accessories can affect the vehicle
performance. See Accessories and
Modifications 0236.
Engine Drag Control (EDC)
EDC improves vehicle stability by sensing if
there is a difference in speed between the
free rolling front wheels and the rear drive
wheels that often occurs when the driver
takes their foot off the accelerator pedal on
slippery surfaces (snow, ice, etc.). When this
is detected, EDC sends more torque to the rear wheels to make sure all four wheels are
spinning at similar speeds, making the
vehicle more stable.
Driver Mode Control
Driver Mode Control adds a sportier feel,
provides a more comfortable ride, or assists
in different weather conditions or terrain.
This system simultaneously changes the
software calibration of various sub-systems
to optimize driving performance. Depending
on the option package, available features,
and mode selected, the exhaust, suspension,
steering, and powertrain will change
calibrations to achieve the desired mode
characteristics. If the vehicle is equipped
with Magnetic Ride Control, selecting the
various Driver Modes adjusts the ride of the
vehicle to enhance the ride performance for
the road conditions and the selected mode.
While in the Sport and/or Track Modes, the
vehicle monitors driving behavior and
automatically enables Performance Shift
Features in the automatic transmission
when spirited driving is detected. These
features maintain lower transmission gears
to increase available engine braking and
improve acceleration response. The vehicle
will exit these features and return to normal
operation after a short period when no
spirited driving is detected.
Driver Mode Control Switch
The Driver Mode Control has three or four
modes: Tour, Sport, Snow/Ice, and Track.
Press
yorzon the MODE switch on the
center console to make a mode selection.
Pressing the switch will display the moding
menu in the instrument cluster with all
available ride modes. Every switch press will
select and activate the next available mode.
When Sport, Snow/Ice, or Track Mode is
selected, a unique and persistent indicator
will be displayed in the instrument cluster.

Chevrolet Camaro Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14583589) - 2021 - CRC - 10/1/20
Driving and Operating 217
Tour Mode
Use for normal city and highway driving to
provide a smooth, soft ride. This setting
provides a balanced setting between comfort
and handling. This is the standard mode.
Sport Mode
Use where road conditions or personal
preference demand a more controlled
response.
When Sport Mode is selected, the
transmission may downshift to a lower gear
for better performance. The transmission
will continue to shift automatically but can
hold a lower gear longer than it would in
the Tour Mode based on braking, throttle
input, and vehicle lateral acceleration. See
Automatic Transmission0206. The steering
will change to provide more precise control.
If the vehicle has Magnetic Ride Control, the
suspension will change to provide better
cornering performance. If the vehicle is
equipped with Active Exhaust, the exhaust
valves will open earlier and more often.
Competitive Driving Mode can be accessed
through this mode by pressing
Yon the
console twice. This Competitive Driving Mode is only on SS,
1LE, and ZL1 vehicles. For example, a vehicle
with a V6 engine and automatic
transmission will have Sport Mode, but will
not be able to access Competitive
Driving Mode.
Snow/Ice Mode
If equipped, use when more traction is
needed during slippery conditions. The
automatic transmission will upshift normally
when the vehicle is moving. The acceleration
will adjust to help provide a smoother
launch. The automatic transmission will also
shift differently to assist in maintaining
traction.
This feature is not intended for use when
the vehicle is stuck in sand, mud, ice, snow,
or gravel. If the vehicle becomes stuck, see
If
the Vehicle Is Stuck 0195.
Track Mode
If equipped, use when maximum vehicle
handling is desired.
When Track Mode is selected, the
transmission may downshift to a lower gear
for better performance. The automatic
transmission and steering will function
similar to Sport Mode.
The accelerator pedal is adjusted to give
maximum control during the highest level of
spirited driving. The Magnetic Ride Control
will be set to the optimum level for vehicle
responsiveness. If the vehicle is equipped
with Active Exhaust, the exhaust valves will
open. Performance Traction Management
(PTM) can be accessed through this mode by
pressing
Yon the console twice.
There are attributes that vary by mode
shown below. Not all vehicles have all
features, depending on the vehicle options.
