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

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.

242 Vehicle Care
If the vehicle has a 6.2L V8 LT4 engine, see
the Camaro High Performance supplement.
Engine Oil
To ensure proper engine performance and
long life, careful attention must be paid to
engine oil. Following these simple, but
important steps will help protect your
investment:
.Use engine oil approved to the proper
specification and of the proper viscosity
grade. See“Selecting the Right Engine
Oil” in this section.
.Check the engine oil level regularly and
maintain the proper oil level. See
“Checking Engine Oil” and“When to Add
Engine Oil” in this section.
.Change the engine oil at the appropriate
time. SeeEngine Oil Life System 0244.
.Always dispose of engine oil properly. See
“What to Do with Used Oil” in this
section.
Checking Engine Oil
Check the engine oil level regularly, every
650 km (400 mi), especially prior to a long
trip. The engine oil dipstick handle is a loop.
See Engine Compartment Overview 0238 for
the location.
{Warning
The engine oil dipstick handle may be
hot; it could burn you. Use a towel or
glove to touch the dipstick handle.
If a low oil Driver Information Center (DIC)
message displays, check the oil level.
Follow these guidelines:
.To get an accurate reading, park the
vehicle on level ground. Check the engine
oil level after the engine has been off for
at least two hours. Checking the engine
oil level on steep grades or too soon after
engine shutoff can result in incorrect
readings. Accuracy improves when
checking a cold engine prior to starting.
Remove the dipstick and check the level.
.If unable to wait two hours, the engine
must be off for at least 15 minutes if the
engine is warm, or at least 30 minutes if
the engine is not warm. Pull out the
dipstick, wipe it with a clean paper towel
or cloth, then push it back in all the way.
Remove it again, keeping the tip down,
and check the level.
When to Add Engine Oil
LTG 2.0L L4 Engine
LGX 3.6L V6 Engine Shown, 6.2L V8 Engine Similar
If the oil is below the cross-hatched area at
the tip of the dipstick and the engine has
been off for at least 15 minutes, add 1 L (1
qt) of the recommended oil and then
recheck the level. See “Selecting the Right
Engine Oil” later in this section for an
explanation of what kind of oil to use. For
engine oil crankcase capacity, see Capacities
and Specifications 0318.
