112 Lighting
Lighting Features
Entry Lighting
Some exterior lamps and interior lamps turn
on briefly at night, or in areas with limited
lighting, when
Kis pressed on the Remote
Keyless Entry (RKE) transmitter. After about
30 seconds the exterior lamps turn off.
Entry lighting can be disabled manually by
turning the ignition on or to ACC/
ACCESSORY, or by pressing
Qon the RKE
transmitter. When any door is opened or
remote unlock pressed, all interior lights
turn on and then interior lamps dim to off
after 20 seconds.
The entry lighting feature for exterior
lighting can be changed. See “Vehicle
Locator Lights” underVehicle Personalization
0 104.
Exit Lighting
Some exterior lamps come on at night or in
areas with limited lighting when the driver
door is opened after the ignition is
turned off.
The interior lamps come on after the
ignition is turned off or any door is opened. The exterior and interior lamps remain on
after the door is closed for a set amount of
time then automatically turn off.
Exit lighting for exterior lights can be
changed. See
Vehicle Personalization 0104.
Theater Dimming
This feature allows for a three to five
second fade out of the interior lamps
instead of having them turn off
immediately.
Battery Load Management
The vehicle has Electric Power Management
(EPM) that estimates the battery's
temperature and state of charge. It then
adjusts the voltage for best performance
and extended life of the battery.
When the battery's state of charge is low,
the voltage is raised slightly to quickly bring
the charge back up. When the state of
charge is high, the voltage is lowered
slightly to prevent overcharging. If the
vehicle has a voltmeter gauge or a voltage
display on the Driver Information Center
(DIC), you may see the voltage move up or
down. This is normal. If there is a problem,
an alert will be displayed. The battery can be discharged at idle if the
electrical loads are very high. This is true for
all vehicles. This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all of the power
needed for very high electrical loads.
A high electrical load occurs when several of
the following are on, such as: headlamps,
high beams, rear window defogger, climate
control fan at high speed, heated seats,
engine cooling fans, trailer loads, and loads
plugged into accessory power outlets.
EPM works to prevent excessive discharge of
the battery. It does this by balancing the
generator's output and the vehicle's
electrical needs. It can increase engine idle
speed to generate more power whenever
needed. It can temporarily reduce the power
demands of some accessories.
Normally, these actions occur in steps or
levels, without being noticeable. In rare
cases at the highest levels of corrective
action, this action may be noticeable to the
driver. If so, a DIC message might be
displayed and it is recommended that the
driver reduce the electrical loads as much as
possible.

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:

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.
