be affected when the light sensor sees a
change in lighting lasting longer than the
delay.
If the vehicle is started in a dark garage, the
automatic headlamp system comes on
immediately. If it is light outside when the
vehicle leaves the garage, there will be a
slight delay before the automatic headlamp
system changes to the DRL. During that
delay, the instrument cluster may not be as
bright as usual. Make sure the instrument
panel brightness control is in the full bright
position. SeeInstrument Panel Illumination
Control 0113.
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
operating, these lamps turn off. Move the
exterior lamp control to
Por;to
disable this feature.
Hazard Warning Flashers
|: Press to make the front and rear turn
signal lamps flash on and off. This warns
others that you are having trouble. Press
again to turn the flashers off.
The hazard warning flashers turn on
automatically if the airbags deploy.
Turn and Lane-Change Signals
Move the lever all the way up or down to
signal a turn.
An arrow on the instrument cluster flashes
in the direction of the turn or lane change.
Raise or lower the lever until the arrow
starts to flash to signal a lane change. Hold
it there until the lane change is completed.
If the lever is briefly pressed and released,
the turn signal flashes three times.
The lever returns to its starting position
whenever it is released.
If after signaling a turn or lane change the
arrow flashes rapidly or does not come on, a
signal bulb may be burned out.
Have any burned out bulbs replaced. If a
bulb is not burned out, check the fuse. See
Electrical System Overload 0265.

188 Driving and Operating
If the vehicle starts to slide, follow these
suggestions:
.Ease your foot off the accelerator pedal
and steer the way you want the vehicle
to go. The vehicle may straighten out. Be
ready for a second skid if it occurs.
.Slow down and adjust your driving
according to weather conditions. Stopping
distance can be longer and vehicle control
can be affected when traction is reduced
by water, snow, ice, gravel, or other
material on the road. Learn to recognize
warning clues—such as enough water,
ice, or packed snow on the road to make
a mirrored surface —and slow down
when you have any doubt.
.Try to avoid sudden steering, acceleration,
or braking, including reducing vehicle
speed by shifting to a lower gear. Any
sudden changes could cause the tires to
slide.
Remember: Antilock brakes help avoid only
the braking skid.
Track Events and Competitive
Driving
{Danger
High-performance features are intended
for use only on closed tracks by
experienced and qualified drivers and
should not be used on public roads.
High-speed driving, aggressive cornering,
hard braking, and other high-performance
driving can be dangerous. Improper driver
inputs for the conditions may result in
loss of control of the vehicle, which could
injure or kill you or others. Always drive
safely.
If the vehicle is a Camaro High Performance
model, see the additional items in the
Camaro High Performance supplement.
Track events or competitive driving may
affect the vehicle warranty. See the
warranty manual before using the vehicle
for racing or other competitive driving.
The Engine Sound Management setting (if
equipped) should not be set to Stealth Mode
during track events and competitive driving.
See Driver Mode Control 0219.
{Warning
Prior to each track event and again
before returning to public roads, tighten
the wheel nuts with a torque wrench to
the proper torque specification. Wheel
nuts that are improperly or incorrectly
tightened can cause the wheels to
become loose or come off, resulting in a
crash. See Capacities and Specifications
0 323 for wheel nut torque specifications.
Engine Oil
Caution
If you use the vehicle for racing or other
competitive driving, the engine may use
more oil than it would with normal use.
Low oil levels can damage the engine. For
information on how to add oil, see
Engine Oil0247.
Be sure to check the oil level often during
racing or other competitive driving and
keep the level at or near the upper mark
that shows the proper operating range on
the engine oil dipstick.

Driving and Operating 197
Warning (Continued)
ignore police warnings and be very
cautious about trying to drive through
flowing water.
Hydroplaning
Hydroplaning is dangerous. Water can build
up under the vehicle's tires so they actually
ride on the water. This can happen if the
road is wet enough and you are going fast
enough. When the vehicle is hydroplaning, it
has little or no contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to slow
down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet weather
driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping equipment in
good shape.
.Keep the windshield washer fluid reservoir
filled.
.Have good tires with proper tread depth.
SeeTires 0272.
.Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through mountains
is different than driving on flat or rolling
terrain. Tips include:
.Keep the vehicle serviced and in good
shape.
.Check all fluid levels and brakes, tires,
cooling system, and transmission.
.Shift to a lower gear when going down
steep or long hills.
{Warning
Using the brakes to slow the vehicle on a
long downhill slope can cause brake
overheating, can reduce brake
performance, and could result in a loss of
braking. Shift the transmission to a lower
gear to let the engine assist the brakes
on a steep downhill slope.
{Warning
Coasting downhill in N (Neutral) or with
the ignition off is dangerous. This can
cause overheating of the brakes and loss
of steering assist. Always have the engine
running and the vehicle in gear.
.Drive at speeds that keep the vehicle in
its own lane. Do not swing wide or cross
the center line.
.Be alert on top of hills; something could
be in your lane (e.g., stalled car, crash).
.Pay attention to special road signs (e.g.,
falling rocks area, winding roads, long
grades, passing or no-passing zones) and
take appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and the road
creates less traction or grip, so drive
carefully. Wet ice can occur at about 0 °C
(32 °F) when freezing rain begins to fall.
Avoid driving on wet ice or in freezing rain
until roads can be treated.

202 Driving and Operating
{Warning
Things inside the vehicle can strike
and injure people in a sudden stop or
turn, or in a crash.
.Put things in the cargo area of the
vehicle. In the cargo area, put
them as far forward as possible.
Try to spread the weight evenly.
.Never stack heavier things, like
suitcases, inside the vehicle so
that some of them are above the
tops of the seats.
.Do not leave an unsecured child
restraint in the vehicle.
.Secure loose items in the vehicle.
.Do not leave a seat folded down
unless needed.
Starting and Operating
New Vehicle Break-In
Caution
Follow these recommended guidelines
during the first 2 414 km (1,500 mi) of
driving this vehicle. Parts have a break-in
period and performance will be better in
the long run.
.Avoid full throttle starts and abrupt
stops.
.Do not exceed 4000 engine rpm.
.Avoid driving at any one constant
speed, fast or slow.
.Do not drive above
129 km/h (80 mph).
.Avoid downshifting to brake or slow
the vehicle when the engine speed
will exceed 4000 rpm.
.Do not let the engine labor. Never lug
the engine in high gear at low speeds.
With a manual transmission, shift to
the next lower gear. This rule applies
at all times, not just during the
break-in period.
(Continued)
Caution (Continued)
.Do not participate in racing events,
sport driving schools, or similar
activities during this break-in period.
.Check engine oil with every refueling
and add if necessary. Oil and fuel
consumption may be higher than
normal during the first
2 414 km (1,500 mi).
.To break in new tires, drive at
moderate speeds and avoid hard
cornering for the first 322 km (200 mi).
New tires do not have maximum
traction and may tend to slip.
.New brake linings also need a break-in
period. Avoid making hard stops
during the first 322 km (200 mi). This
is recommended every time brake
linings are replaced.
.Should the vehicle be used for racing
or competitive driving (after break-in),
the rear axle lubricant must be
replaced beforehand.

206 Driving and Operating
If equipped, the engine heater can help in
cold weather conditions at or below−18 °C
(0 °F) for easier starting and better fuel
economy during engine warm-up. Plug in
the coolant heater at least four hours before
starting the vehicle. An internal thermostat
in the plug end of the cord will prevent
engine heater operation at temperatures
above −18 °C (0 °F).
Using the Engine Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
The electrical cord is on the passenger
side of the engine compartment, next to
the engine compartment fuse block.
Check the heater cord for damage. If it is
damaged, do not use it. See your dealer
for a replacement. Inspect the cord for
damage yearly.
3. Plug it into a normal, grounded 110-volt AC outlet.
{Warning
Improper use of the heater cord or an
extension cord can damage the cord and
may result in overheating and fire.
.Plug the cord into a three-prong
electrical utility receptacle that is
protected by a ground fault detection
function. An ungrounded outlet could
cause an electric shock.
.Use a weatherproof, heavy-duty,
15 amp-rated extension cord if needed.
Failure to use the recommended
extension cord in good operating
condition, or using a damaged heater
(Continued)
Warning (Continued)
or extension cord, could make it
overheat and cause a fire, property
damage, electric shock, and injury.
.Do not operate the vehicle with the
heater cord permanently attached to
the vehicle. Possible heater cord and
thermostat damage could occur.
.While in use, do not let the heater
cord touch vehicle parts or sharp
edges. Never close the hood on the
heater cord.
.Before starting the vehicle, unplug the
cord, reattach the cover to the plug,
and securely fasten the cord. Keep the
cord away from any moving parts.
4. Before starting the engine, be sure to unplug and store the cord as it was
before to keep it away from moving
engine parts. If you do not it could be
damaged.
The length of time the heater should remain
plugged in depends on several factors. Ask a
dealer in the area where you will be parking
the vehicle for the best advice on this.

Retained Accessory Power (RAP)
When the ignition is turned from on to off,
the following features (if equipped) will
continue to function for up to 10 minutes,
or until the driver door is opened. These
features will also work when the ignition is
in RUN or ACC/ACCESSORY:
.Infotainment System
.Power Windows (during RAP this
functionality will be lost when any door
is opened)
.Sunroof (during RAP this functionality will
be lost when any door is opened)
.Auxiliary Power Outlet
.Audio System
.OnStar System
Shifting Into Park
To shift into P (Park):1. Hold the brake pedal down and set the parking brake.
See Electric Parking Brake 0216.
2. Move the shift lever into P (Park) by holding in the button on the shift lever
and pushing the shift lever all the way
toward the front of the vehicle.
3. Turn the ignition off.
Leaving the Vehicle with the Engine
Running
{Warning
It can be dangerous to leave the vehicle
with the engine running. It could
overheat and catch fire.
It is dangerous to get out of the vehicle
if the shift lever is not fully in P (Park)
with the parking brake firmly set. The
vehicle can roll.
Do not leave the vehicle when the engine
is running. If you have left the engine
running, the vehicle can move suddenly.
You or others could be injured. To be
sure the vehicle will not move, even
when you are on fairly level ground,
always set the parking brake and move
the shift lever to P (Park). See Shifting
Into Park 0207.
If you have to leave the vehicle with the
engine running, be sure the vehicle is in
P (Park) and the parking brake is set before
you leave it. After you have moved the shift
lever into P (Park), hold the brake pedal down. Then, see if you can move the shift
lever away from P (Park) without first
pressing the button on the shift lever.
Release the button and check that the shift
lever cannot be moved out of P (Park).
Torque Lock
Torque lock is when the weight of the
vehicle puts too much force on the parking
pawl in the transmission. This happens when
parking on a hill and shifting the
transmission into P (Park) is not done
properly and then it is difficult to shift out
of P (Park). To prevent torque lock, set the
parking brake and then shift into P (Park). To
find out how, see
“Shifting Into Park”
previously in this section.
If torque lock does occur, the vehicle may
need to be pushed uphill by another vehicle
to relieve the parking pawl pressure, so you
can shift out of P (Park).
Shifting out of Park
This vehicle is equipped with an electronic
shift lock release system. The shift lock
release is designed to prevent movement of
the shift lever out of P (Park), unless the
ignition is on and the brake pedal is applied.

Driving and Operating 215
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.
