Driving and Operating 185
.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 0216.
{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
0 318 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 Oil0242.
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.

Chevrolet Camaro Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14583589) - 2021 - CRC - 10/1/20
186 Driving and Operating
3.6L (LGX) V6 Engine
Change the engine oil to 0W-40 or 5W-40
that meets the dexos2 specification. If this
oil is not available, the following oil can be
used as an alternative: Valvoline SYNPOWER
MST 5W-40.
For LS/LT 1LE, add 0.9 L (1.0 qt) of oil over
the nominal fill level for a track event. After
the competitive driving, remove the excess
oil so that the level on the dipstick is not
above the upper mark that shows the
proper operating range.
During track usage, do not follow the Engine
Oil Life System status. Change the engine oil
after four hours of accumulative track usage.
Fuel
Use premium unleaded gasoline with a
posted octane rating of 93 at a track event.
Unleaded gasoline with a posted octane
rating of 91 may be used, but performance
will be degraded.
Automatic Transmission Fluid
Have the transmission fluid set to the track
specific oil level prior to track usage.
Transmission fluid should be changed afterevery 15 hours of track usage. Any
transmission level set or change should be
performed at your dealer.
Manual Transmission Fluid
Manual transmission fluid should be
changed after every 15 hours of track usage.
Rear Axle Fluid
Axles must have 2 400 km (1,500 mi) before
being used in track driving.
The rear axle fluid temperatures may be
higher than when driving in severe
conditions. Drain and refill with new fluid
after the first racing or competitive driving
event, and then after every 24 hours of
racing or competitive driving. See
Recommended Fluids and Lubricants
0313.
Caution
During a first time track or racing event,
high rear axle temperatures can occur.
Damage could be caused to the rear axle
and would not be covered by the vehicle
warranty. Do not drive as long or as fast
the first time the vehicle is driven on the
track or raced.
Brake Fluid
For track events or competitive driving, it is
recommended that the brake fluid be
replaced with a high performance brake fluid
that has a dry boiling point greater than
279 °C (534 °F). After conversion to the high
performance brake fluid, follow the brake
fluid service recommendations outlined by
the fluid manufacturer. Do not use silicone
or DOT-5 brake fluids.
Brake Burnishing
To prepare the Camaro brake systems for
track events and racing, complete the
appropriate high performance brake
burnishing procedure described below.
New brake pads must be burnished before
racing or competitive driving.
Caution
These procedures are specific to the
Camaro LT with Y4Q Heavy Duty Cooling
System and J55 brakes, SS, ZL1, and
models equipped with the 1LE track
package. This procedure should not be
run on other Camaro models equipped

Driving and Operating 187
Caution (Continued)
with JL9 or J55 brakes without Y4Q heavy
duty cooling system as damage may
result.
Caution
The new vehicle break-in period should be
completed before performing the brake
burnishing procedure or damage may
occur to the powertrain/engine. SeeNew
Vehicle Break-In 0199.
When performed as instructed, this
procedure will not damage the brakes.
During the burnishing procedure, the brake
pads will smoke and produce an odor. The
braking force and pedal travel may increase.
After the procedure is complete, the brake
pads may appear white at the rotor contact.
Run this procedure in a safe manner and in
compliance with all local and state
ordinances/laws regarding motor vehicle
operation. Run this procedure only on dry
pavement. Racing/Track Brake Burnishing Procedure
Caution
Brake fade will occur during this track
burnish procedure and can cause brake
pedal travel and force to increase. This
could extend stopping distance until the
brakes are fully burnished.
1. Apply the brakes 25 times starting at 100 km/h (60 mph) to 50 km/h (30 mph)
while decelerating at 0.4 g. This is a
medium brake application. Drive for at
least 1 km (0.6 mi) between applying the
brakes. This first step may be skipped if
there are more than 320 km (200 mi) on
the brake pads.
2. Repeatedly apply the brakes from 100 km/h (60 mph) to 25 km/h (15 mph)
while decelerating at 0.8 g. This is a hard
brake application, without activating the
Antilock Brake System (ABS). Drive for at
least 1 km (0.6 mi) between stops. Repeat
until the brake pedal travel starts to
increase. Depending on conditions, this
should take no longer than 25 brake
applications. 3. Cool down: Drive at 100 km/h (60 mph)
for approximately 15 km (10 mi) without
using the brakes.
4. Apply the brakes 25 times from 100 km/h (60 mph) to 50 km/h (30 mph)
while decelerating at 0.4 g. This is a
medium brake application. Drive for at
least 1 km (0.6 mi) between applications.
Front Tire Deflectors, Lower Control Arm
Deflectors, and Disc Splash Shields (SS
except 1LE Only)
Before any racing event, remove the tire
deflectors in the front of the vehicle, and
replace the original deflector and splash
shield with the tall deflector and small
splash shield.
Caution
Race track driving with the original front
disc brake splash shield and front tire
deflector may result in brake pedal fade
due to high rotor temperatures.
To install the tall deflector and small splash
shield:

track where there is a large clear area
around all sides of the vehicle. Be ready
to apply the brakes immediately if the
vehicle begins to move. Do not use Line
Lock in an area that is accessible to the
public or where people or property are
located near the vehicle.
Caution
Attempting to shift when the drive
wheels are spinning and do not have
traction may cause damage to the
transmission. Damage caused by misuse
of the vehicle is not covered by the
vehicle warranty. Do not attempt to shift
when the drive wheels do not have
traction.
Line Lock allows for locking the front brakes
independently of the rear brakes. This allows
the rear tires to spin when the throttle is

Driving on Wet Roads
Rain and wet roads can reduce vehicle
traction and affect your ability to stop and
accelerate. Always drive slower in these
types of driving conditions and avoid driving
through large puddles and deep-standing or
flowing water.
{Warning
Wet brakes can cause crashes. They
might not work as well in a quick stop
and could cause pulling to one side. You
could lose control of the vehicle.
After driving through a large puddle of
water or a car/vehicle wash, lightly apply
the brake pedal until the brakes work
normally.
Flowing or rushing water creates strong
forces. Driving through flowing water
could cause the vehicle to be carried
away. If this happens, you and other
vehicle occupants could drown. Do not (Continued)
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 0267.

Chevrolet Camaro Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14583589) - 2021 - CRC - 10/1/20
194 Driving and Operating
.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.For Slippery Road Driving:
.Accelerate gently. Accelerating too quickly
causes the wheels to spin and makes the
surface under the tires slick.
.Turn on Traction Control. See
Traction
Control/Electronic Stability Control 0214.
.The Antilock Brake System (ABS) improves
vehicle stability during hard stops, but
the brakes should be applied sooner than
when on dry pavement. See Antilock
Brake System (ABS) 0212.
.Allow greater following distance and
watch for slippery spots. Icy patches can
occur on otherwise clear roads in shaded
areas. The surface of a curve or an
overpass can remain icy when the
surrounding roads are clear. Avoid sudden
steering maneuvers and braking while
on ice.
.Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place and signal
for help. Stay with the vehicle unless there
is help nearby. If possible, use Roadside
Assistance. See Roadside Assistance Program
0 326. To get help and keep everyone in the
vehicle safe:
.Turn on the hazard warning flashers.

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.
See Track Events and Competitive Driving
0 185.
Ignition Positions
The vehicle has an electronic keyless ignition
with pushbutton start.
The Remote Keyless Entry (RKE) transmitter
must be in the vehicle for the system to
operate. If the pushbutton start is not
working, the vehicle may be near a strong
radio antenna signal causing interference to
the Keyless Access system. See Remote
Keyless Entry (RKE) System Operation 07.
To shift out of P (Park), the vehicle must be
on and the brake pedal must be applied.
