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.
SeeHead-Up Display (HUD) 0101.
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.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 malfunction indicator lamp will be on. See
Malfunction
Indicator Lamp 092. 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.
Chevrolet Camaro Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14583589) - 2021 - CRC - 3/24/20
218 Driving and Operating
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.
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 getsstuck in sand, mud, ice, or snow. See
If the
Vehicle Is Stuck 0198 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.

Adding accessories can affect the vehicle
performance. See Accessories and
Modifications 0240.
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.

14583589) - 2021 - CRC - 3/24/20
220 Driving and Operating
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 SwitchThe 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.
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 Transmission
0209. 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.

Cruise Control
When using cruise control, the vehicle can
maintain a speed of about 40 km/h (25 mph)
or more without keeping your foot on the
accelerator. 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 a manual transmission, the
cruise control will remain active when the
gears are shifted. The cruise is disengaged if
the clutch is pressed for several seconds.
If the 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 0218.
When road conditions allow you to safely
use it again, cruise control can be turned
back on.
Cruise control will disengage if either TCS or
StabiliTrak/ESC is turned off.
Cruise control is not available when using
Competitive Driving Mode, if equipped. See
Competitive Driving Mode (SS, ZL1 and 1LE
Models Only) 0223.
If the brakes are applied, cruise control
disengages.

(1 mph) slower. The speedometer reading can be displayed
in either English or metric units. See
“Options”
underInstrument Cluster 083.
The increment value used depends on the
units displayed.
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 slows down to the
previously set cruise control speed. While
pressing the accelerator pedal or shortly
following the release to override cruise
control, briefly pressing SET– will result in
cruise control set to the current vehicle
speed.
Using Cruise Control on Hills
How well the cruise control works 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 the vehicle
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 will disengage.

Displayed images may be farther or closer
than they appear. The area displayed is
limited and objects that are close to either
corner of the bumper or under the bumper
do not display.
A warning triangle may display to show
that Rear Park Assist (RPA) or Rear Cross
Traffic Alert (RCTA) has detected an object.
This triangle changes from amber to red and
increases in size the closer the object.
{Warning
The camera(s) do not display children,
pedestrians, bicyclists, crossing traffic,
animals, or any other object outside of
the cameras’field of view, below the
bumper, or under the vehicle. Shown
distances may be different from actual
distances. Do not drive or park the
vehicle using only these camera(s).
Always check behind and around the
vehicle before driving. Failure to use
proper care may result in injury, death,
or vehicle damage. Park Assist
With RPA, as the vehicle backs up at speeds
of less than 8 km/h (5 mph), the sensors on
the rear bumper may detect objects up to
2.5 m (8 ft) behind the vehicle within a zone
25 cm (10 in) high off the ground and below
bumper level. These detection distances may
be shorter during warmer or humid weather.
Blocked sensors will not detect objects and
can also cause false detections. Keep the
sensors clean of mud, dirt, snow, ice, and
slush; and clean sensors after a car wash in
freezing temperatures.
{Warning
The Park Assist system does not detect
children, pedestrians, bicyclists, animals,
or objects located 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 moving forward or backing.
The instrument cluster may have a Park
Assist display with bars that show
“distance
to object” and object location information
for RPA. As the object gets closer, more bars
light up and the bars change color from
yellow to amber to red.
When an object is first detected in the rear,
one beep will be heard from the rear. When
an object is very close (<0.6 m (2 ft) in the
vehicle rear), five beeps will sound from
the rear.
Rear Cross Traffic Alert (RCTA)
If equipped, RCTA displays a red warning
triangle with a left or right pointing arrow
to warn of traffic coming from the left or
right. This system detects objects coming
from up to 20 m (65 ft) from the left or
right side of the vehicle. When an object is

Vehicle Care 257
If the coolant still is not at the proper levels
when the system cools down again, see
your dealer.
Engine Overheating
The vehicle has several indicators to warn of
the engine overheating.
There is an engine coolant temperature
gauge on the instrument cluster. SeeEngine
Coolant Temperature Gauge 089. The
vehicle may also display a message on the
Driver Information Center (DIC).
If the decision is made not to lift the hood
when this warning appears, get service help
right away. See Roadside Assistance Program
0 329.
If the decision is made to lift the hood,
make sure the vehicle is parked on a level
surface.
Then check to see if the engine cooling fan
is running. If the engine is overheating, the
fan should be running. If it is not, do not
continue to run the engine. Have the vehicle
serviced.
Caution
Do not run the engine if there is a leak
in the engine cooling system. This can
cause a loss of all coolant and can
damage the system and vehicle. Have
any leaks fixed right away.
If Steam Is Coming from the Engine
Compartment
{Warning
Steam and scalding liquids from a hot
cooling system are under pressure.
Turning the pressure cap, even a little,
can cause them to come out at high
speed and you could be burned. Never
turn the cap when the cooling system,
including the pressure cap, is hot. Wait
for the cooling system and pressure cap
to cool.
If Steam Is Coming from the Engine
Compartment with no Overheat Warning
The hood extractor, if equipped, is
functional. It will allow water from rain and
car washes to enter the engine
compartment and contact hot surfaces. If steam is coming from the hood extractor
with no accompanying overheat warning, no
service is needed.
If No Steam Is Coming from the Engine
Compartment
If an engine overheat warning is displayed
but no steam can be seen or heard, the
problem may not be too serious. Sometimes
the engine can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day
.Stops after high-speed driving
.Idles for long periods in traffic
If the overheat warning is displayed with no
sign of steam: 1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest fan
speed. Open the windows as necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or N (Neutral) for
an automatic transmission or Neutral for
a manual transmission, and let the
engine idle.
If the engine coolant temperature gauge is
no longer in the overheated area, the
vehicle can be driven. Continue to drive the
