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.

Parking (Manual Transmission)
{Warning
If the vehicle has a manual transmission,
never get out of the vehicle without first
moving the shift lever into 1st or
R (Reverse), setting the parking brake and
turning the ignition off. The vehicle can
roll, which could cause serious injury or
death.
Parking over Things That Burn
{Warning
Things that can burn could touch hot
exhaust parts under the vehicle and
ignite. Do not park over papers, leaves,
dry grass, or other things that can burn.
Active Fuel Management
Vehicles with V6 and V8 engines and an
automatic transmission have Active Fuel
Management. This system allows the engine
to operate on either all or four of its
cylinders, depending on the driving
conditions.When less power is required, such as
cruising at a constant vehicle speed, the
system will operate in four cylinder mode,
allowing the vehicle to achieve better fuel
economy. When greater power demands are
required, such as accelerating from a stop,
passing, or merging onto a freeway, the
system will maintain full-cylinder operation.
Extended Parking
It is best not to park with the vehicle
running. If the vehicle is left running, be
sure it will not move and there is adequate
ventilation. See
Shifting Into Park 0203 and
Engine Exhaust 0205.
If the vehicle is left parked and running with
the Remote Keyless Entry (RKE) transmitter
outside the vehicle, it will continue to run
for up to half an hour.
If the vehicle is left parked and running with
the RKE transmitter inside the vehicle, it will
continue to run for up to an hour.
The vehicle could turn off sooner if it is
parked on a hill, due to lack of
available fuel.
Automatic Transmission
The timer will reset if the vehicle is taken
out of P (Park) while it is running. Manual Transmission
The timer will reset if vehicle speed exceeds
4 km/h (2.5 mph).
Engine Exhaust
{
Warning
Engine exhaust contains carbon monoxide
(CO), which cannot be seen or smelled.
Exposure to CO can cause
unconsciousness and even death.
Exhaust may enter the vehicle if:
.The vehicle idles in areas with poor
ventilation (parking garages, tunnels,
deep snow that may block underbody
airflow or tail pipes).
.The exhaust smells or sounds strange
or different.
.The exhaust system leaks due to
corrosion or damage.
.The vehicle exhaust system has been
modified, damaged, or improperly
repaired. (Continued)

back of the steering wheel. Tap the left
paddle (−) to downshift, and the right
paddle (+) to upshift. The Driver Information
Center (DIC) display indicates the gear the
vehicle is in.
Holding the left paddle for an extended time
will downshift the transmission to the
lowest available gear.
While in Manual Mode, the transmission will
prevent shifting to a lower gear if the
engine speed is too high. If the tap down
−(Minus) paddle is held while the vehicle
slows down, the M in the DIC will flash, and
the downshift will be allowed when vehicle
speed is low enough. Continuing to hold the
tap down −(Minus) paddle will not cause
the transmission to continue downshifting.
Each downshift must be requested
separately by releasing and reapplying the
tap down −(Minus) paddle.
Head-Up Display (HUD)
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.
See
Head-Up Display (HUD) 0100.
Temporary Tap Shift Mode allows brief
entry into Tap Shift Mode while in D (Drive).
Tapping either the upshift or downshift
control will place the transmission in Tap
Shift Mode. Exit Tap Shift Mode by holding
the upshift control for two seconds. The
system will return to automatic shifting
after seven seconds of driving at a steady
speed, or when the vehicle comes to a stop.
This may be used for sport driving or when
climbing or descending hills, to stay in gear
longer, or to downshift for more power or
engine braking. The transmission will only
allow you to shift into gears appropriate for
the vehicle speed and engine revolutions per
minute (rpm). The transmission will not
automatically shift to the next higher gear if
the engine rpm is too high. If shifting is
prevented for any reason, the gear displayed
in the DIC will blink several times, indicating
that the transmission has not shifted gears. While in the Tap Shift Mode, the
transmission will not automatically
downshift on hard acceleration.

briefly press the center of the valve stem.
When the recommended pressure is reached,
the horn sounds once.
If the turn signal lamp does not flash within
15 seconds after starting to inflate the tire,
the tire fill alert has not been activated or is
not working.
If the hazard warning flashers are on, the
tire fill alert visual feedback will not work
properly.
The TPMS will not activate the tire fill alert
properly under the following conditions:
.There is interference from an external
device or transmitter.
.The air pressure from the inflation device
is not sufficient to inflate the tire.
.There is a malfunction in the TPMS.
.There is a malfunction in the horn or turn
signal lamps.
.The identification code of the TPMS
sensor is not registered to the system.
.The battery of the TPMS sensor is low.
If the tire fill alert does not operate due to
TPMS interference, move the vehicle about
1 m (3 ft) back or forward and try again.
If the tire fill alert feature is not working,
use a tire pressure gauge.
TPMS Sensor Matching Process
Each TPMS sensor has a unique
identification code. The identification code
needs to be matched to a new tire/wheel
position after rotating the vehicle’s tires or
replacing one or more of the TPMS sensors.
The TPMS sensor matching process should
also be performed after replacing a spare
tire with a road tire containing the TPMS
sensor. The malfunction light and the DIC
message should go off at the next ignition
cycle. The sensors are matched to the tire/
wheel positions, using a TPMS relearn tool,
in the following order: driver side front tire,
passenger side front tire, passenger side rear
tire, and driver side rear. See your dealer for
service or to purchase a relearn tool.
A TPMS relearn tool can also be purchased.
See Tire Pressure Monitor Sensor Activation
Tool at www.gmtoolsandequipment.com or
call 1-800-GM TOOLS (1-800-468-6657).
There are two minutes to match the first
tire/wheel position, and five minutes overall
to match all four tire/wheel positions. If it
takes longer, the matching process stops
and must be restarted.
The TPMS sensor matching process is: 1. Set the parking brake. 2. Place the vehicle in Service Mode. See
Ignition Positions 0199.
3. Make sure the Tire Pressure info display option is turned on. The info displays on
the DIC can be turned on and off
through the Options menu. See Driver
Information Center (DIC) 097.
4. Use the five-way DIC control on the right side of the steering wheel to scroll to
the Tire Pressure screen under the DIC
info page. See Driver Information Center
(DIC) 097.
5. Press and hold SEL in the center of the five-way DIC control.
The horn sounds twice to signal the
receiver is in relearn mode and the TIRE
LEARNING ACTIVE message displays on
the DIC screen.
6. Start with the driver side front tire.
7. Place the relearn tool against the tire sidewall, near the valve stem. Then press
the button to activate the TPMS sensor.
A horn chirp confirms that the sensor
identification code has been matched to
this tire and wheel position.
8. Proceed to the passenger side front tire, and repeat Step 7.
