90 Instruments and Controls
If the gauge pointer moves to the high end,
the engine is too hot.
This reading indicates the same thing as the
warning light. It means that the engine
coolant has overheated. If the vehicle has
been operating under normal driving
conditions, pull off the road, stop the
vehicle, and turn off the engine as soon as
possible. SeeEngine Overheating 0257 for
more information.
Voltmeter Gauge (Uplevel
Cluster Only)
Standard Theme
When the ignition is on, this gauge indicates
the battery voltage. When the engine is running, this gauge
shows the condition of the charging system.
The gauge can transition from a higher to
lower or a lower to higher reading. This is
normal. If the vehicle is operating outside
the normal operating range, the charging
system light comes on. See
Charging System
Light 092.
Readings outside the normal operating
range can also occur when a large number
of electrical accessories are operating in the
vehicle and the engine is left idling for an
extended period. This condition is normal
since the charging system is not able to
provide full power at engine idle. As engine
speeds are increased, this condition should
correct itself as higher engine speeds allow
the charging system to create maximum
power.
The vehicle can only be driven for a short
time with the readings outside the normal
operating range. If the vehicle must be
driven, turn off all accessories, such as the
radio and air conditioner, and unplug all
chargers and accessories.
Readings outside the normal operating
range indicate a possible problem in the
electrical system. Have the vehicle serviced
as soon as possible.
Seat Belt Reminders
Driver Seat Belt Reminder Light
There is a driver seat belt reminder light on
the instrument cluster.
When the vehicle is started, this light
flashes and a chime may come on to remind
the driver to fasten their seat belt.
Then the light stays on solid until the belt is
buckled. This cycle may continue several
times if the driver remains or becomes
unbuckled while the vehicle is moving.
If the driver seat belt is buckled, neither the
light nor the chime comes on.
Front Passenger Seat Belt Reminder
Light
The vehicle may have a front passenger seat
belt reminder light near the passenger
airbag status indicator. See Passenger
Sensing System 054.

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.

Driving and Operating 199
Warning (Continued)
overheat, causing an engine compartment
fire or other damage. Spin the wheels as
little as possible and avoid going above
56 km/h (35 mph).
Rocking the Vehicle to Get it Out
Turn the steering wheel left and right to
clear the area around the front wheels. Turn
off any traction system. Shift back and forth
between R (Reverse) and a low forward gear,
spinning the wheels as little as possible. To
prevent transmission wear, wait until the
wheels stop spinning before shifting gears.
Release the accelerator pedal while shifting,
and press lightly on the accelerator pedal
when the transmission is in gear. Slowly
spinning the wheels in the forward and
reverse directions causes a rocking motion
that could free the vehicle. If that does not
get the vehicle out after a few tries, it
might need to be towed out. If the vehicle
does need to be towed out, seeTowing the
Vehicle 0299.
Vehicle Load Limits
It is very important to know how much
weight the vehicle can carry. This
weight is called the vehicle capacity
weight and includes the weight of all
occupants, cargo, and all
nonfactory-installed options. Two labels
on the vehicle may show how much
weight it may properly carry: the Tire
and Loading Information label and the
Certification label.
{Warning
Do not load the vehicle any heavier
than the Gross Vehicle Weight Rating
(GVWR), or either the maximum
front or rear Gross Axle Weight
Rating (GAWR). This can cause
systems to break and change the
way the vehicle handles. This could
cause loss of control and a crash.
Overloading can also reduce stopping
distance, damage the tires, and
shorten the life of the vehicle. Tire and Loading Information LabelLabel Example
A vehicle-specific Tire and Loading
Information label is attached to the
vehicle's center pillar (B-pillar). The Tire
and Loading Information label shows
the number of occupant seating
positions (1), and the maximum vehicle
capacity weight (2) in kilograms and
pounds.
The Tire and Loading Information label
also shows the tire size of the original
equipment tires (3) and the
recommended cold tire inflation

Driving and Operating 205
Hold the clutch pedal down to the floor,
press the brake pedal, then press ENGINE
START/STOP.
If there is no RKE transmitter in the
vehicle or if there is something causing
interference with it, the Driver
Information Center (DIC) will display a
message.
2. When the engine begins cranking, let go of the button and the engine cranks
automatically until it starts. If the
battery in the RKE transmitter is weak,
the DIC will display a message. The
vehicle can still be driven.
See “Starting the Vehicle with a Low
Transmitter Battery” underRemote
Keyless Entry (RKE) System Operation 07
. If the RKE transmitter battery is dead,
insert it into the rear cupholder to
enable engine starting.
3. 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.
4. If the engine does not start and no DIC message is displayed, wait 15 seconds
before trying again to let the cranking
motor cool down. 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 while cranking for up to
15 seconds maximum. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down. When
the engine starts, let go of the
accelerator. If the vehicle starts briefly
but then stops again, repeat these steps.
This clears the extra gasoline from the
engine.
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.
Stopping the Engine
If the vehicle has an automatic transmission,
move the shift lever to P (Park) and press
and hold ENGINE START/STOP on the instrument panel, until the engine shuts off.
If the shift lever is not in P (Park), the
engine shuts off and the ignition goes to
ACC/ACCESSORY. The DIC displays SHIFT TO
PARK. Once the shift lever is moved to
P (Park), the vehicle turns off.
If the vehicle has a manual transmission,
before getting out of the vehicle, shift to
1 (First) or R (Reverse) and apply the parking
brake. Then turn off the ignition off by
pressing ENGINE START/STOP and release
the clutch pedal when the engine has
stopped.
If the RKE transmitter is not detected inside
the vehicle when it is turned off the DIC
displays a message.
Engine Heater
{Warning
Do not plug in the engine block heater
while the vehicle is parked in a garage or
under a carport. Property damage or
personal injury may result. Always park
the vehicle in a clear open area away
from buildings or structures.

Chevrolet Camaro Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14583589) - 2021 - CRC - 3/24/20
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.

6.2L V8 Engine (LT1)
1. Engine Coolant Surge Tank andPressure Cap
2. Engine Cooling Fan (Out of View)
{Warning
An underhood electric fan can start up
even when the engine is not running and
can cause injury. Keep hands, clothing,
and tools away from any underhood
electric fan.
{Warning
Do not touch heater or radiator hoses,
or other engine parts. They can be very
hot and can burn you. Do not run the
engine if there is a leak; all coolant could
leak out. That could cause an engine fire
and can burn you. Fix any leak before
driving the vehicle.
Engine Coolant
The cooling system in the vehicle is filled
with DEX-COOL engine coolant. See
Maintenance Schedule 0310 and
Recommended Fluids and Lubricants 0318.
The following explains the cooling system
and how to check and add coolant when it
is low. If there is a problem with engine
overheating, see Engine Overheating 0257.
What to Use
{Warning
Plain water, or other liquids such as
alcohol, can boil before the proper
coolant mixture will. With plain water or
the wrong mixture, the engine could get
(Continued)
Warning (Continued)
too hot but there would not be an
overheat warning. The engine could catch
fire and you or others could be burned.
Use a 50/50 mixture of clean drinkable
water and DEX-COOL coolant. This mixture:
.Gives freezing protection down to −37 °C
(−34 °F), outside temperature
.Gives boiling protection up to 129 °C
(265 °F), engine temperature
.Protects against rust and corrosion
.Will not damage aluminum parts
.Helps keep the proper engine
temperature
Caution
Do not use anything other than a mix of
DEX-COOL coolant that meets GM
Standard GMW3420 and clean, drinkable
water. Anything else can cause damage
to the engine cooling system and the
vehicle, which would not be covered by
the vehicle warranty.
Never dispose of engine coolant by putting
it in the trash, pouring it on the ground,
or into sewers, streams, or bodies of water.

Chevrolet Camaro Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14583589) - 2021 - CRC - 3/24/20
Vehicle Care 255
Have the coolant changed by an authorized
service center, familiar with legal
requirements regarding used coolant
disposal. This will help protect the
environment and your health.
Checking Coolant
The vehicle must be on a level surface when
checking the coolant level.
It is normal to see coolant moving in the
upper coolant hose return line when the
engine is running. It is also normal to see
bubbles entering the surge tank through the
small hose.Check to see if coolant is visible in the
coolant surge tank. If the coolant inside the
coolant surge tank is boiling, do not do
anything else until it cools down.
If coolant is visible but the coolant level is
not at or above the cold fill line, add a 50/
50 mixture of clean drinkable water and
DEX-COOL coolant.
Be sure the cooling system is cool before
this is done.
It is normal for the coolant level in the
bottom chamber to rise and fall with
operating temperature and ambient
conditions. Coolant will evaporate from the
bottom chamber in normal operation. This
will happen faster when the vehicle is driven
for long periods in hot, dry conditions.
If no coolant is visible in the coolant surge
tank, add coolant as follows:
How to Add Coolant to the Coolant
Surge Tank
If no problem is found, check to see if
coolant is visible in the coolant surge tank.
If coolant is visible but the coolant level is
not at the bottom of the fill neck, add a 50/
50 mixture of clean, drinkable water and
DEX-COOL coolant at the coolant surge tank,but be sure the cooling system, including
the coolant surge tank pressure cap, is cool
before you do it.
{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.
{Warning
Plain water, or other liquids such as
alcohol, can boil before the proper
coolant mixture will. With plain water or
the wrong mixture, the engine could get
too hot but there would not be an
overheat warning. The engine could catch
fire and you or others could be burned.

256 Vehicle Care
{Warning
Spilling coolant on hot engine parts can
burn you. Coolant contains ethylene
glycol and it will burn if the engine parts
are hot enough.
Caution
Failure to follow the specific coolant fill
procedure could cause the engine to
overheat and could cause system
damage. If coolant is not visible in the
surge tank, contact your dealer.
1. Remove the coolant surge tank pressurecap from the top chamber when the
cooling system, including the coolant
surge tank pressure cap and upper
radiator hose, is no longer hot. Turn the pressure cap slowly
counterclockwise. If you hear a hiss, wait
for that to stop. This will allow any
pressure still left to be vented out the
discharge hose.
2. Keep turning the pressure cap slowly and remove it. Open the surge tank service
port cap to the lower chamber.3. Fill the surge tank top chamber with theproper mixture to the bottom of the fill
neck. The top chamber needs to be
completely full. Fill the surge tank
bottom chamber through the service port
to approximately half. 4. With the coolant surge tank pressure cap
off and the surge tank service port cap
open, start the engine and let it run
until you can feel the upper radiator
hose getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level inside the
coolant surge tank top chamber may be
lower. If the level is lower, add more of
the proper mixture to the surge tank top
chamber until the level reaches the
bottom of the fill neck.
5. Replace the surge tank pressure cap tightly and close the surge tank service
port cap.
Caution
If the pressure cap is not tightly installed,
coolant loss and engine damage may
occur. Be sure the cap is properly and
tightly secured.
Check the level in the surge tank top and
bottom chambers when the cooling system
has cooled down. If the coolant is not at the
proper levels, repeat Steps 1–3 and reinstall
the pressure cap and close the service port.
