114 Instruments and Controls
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when
it comes on may prevent damage.
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not
run smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not
meet the original tire
specifications, can cause this light
to come on. This could lead to
costly repairs not covered by the
vehicle warranty. This could also
affect the vehicle’s ability to pass
an Emissions Inspection/
Maintenance test. See
Accessories and Modifications
0220.
If the light is flashing : A
malfunction has been detected that
could damage the emission control
system and increase vehicle
emissions. Diagnosis and service
may be required.
To help prevent damage, reduce
vehicle speed and avoid hard
accelerations and uphill grades. If the light continues to flash, find a
safe place to park. Turn the vehicle
off and wait at least 10 seconds
before restarting the engine. If the
light is still flashing, follow the
previous guidelines and see your
dealer for service as soon as

. If fuel has been added to the
vehicle using the capless funnel
adapter, make sure that it has
been removed. See “Filling the
Tank with a Portable Gas Can”
under Filling the Tank 0214.
The diagnostic system can
detect if the adapter has been
left installed in the vehicle,
allowing fuel to evaporate into
the atmosphere. A few driving
trips with the adapter removed
may turn off the light.

162 Driving and Operating
vehicle for racing or other
competitive driving. SeeCompetitive
Driving Mode 0203.
A manual transmission is
recommended for extended track
usage at higher ambient
temperatures. Consult the Track
Preparation Guide for additional
information. See your dealer.
Be sure to follow all service
procedures before driving the
vehicle at track events or
competitively.
Prior to each track event and again
before re-entering the public road
system, tighten the wheel nuts with
a torque wrench to the proper
torque specification. See Capacities
and Specifications 0326.Engine Sound Management
Setting
Caution
Do not place the vehicle in
Engine Sound Management –
Stealth mode. Damage could
result to exhaust valve actuators.
Engine Oil
Caution
If the vehicle is used for track
events and competitive driving,
the engine may use more oil than
it would with normal use. Low oil
levels can damage the engine.
Check the oil level often and
maintain the proper level. See
Engine Oil0232.
The engine is factory filled with
0W-40 dexos2 oil. For LT1 and LT4
engines only, 0W-40 dexos2 engine
oil is approved for both track and
street use. 15W-50 full synthetic engine oil may also be used for
track use, but after track use must
be changed back to 0W-40 dexos2
for street use. If 0W-40 dexos2 oil is
not available, 5W-30 dexos1 full
synthetic engine oil may be used for
street use. If 5W-30 dexos1 is used,
it must be changed to 0W-40
dexos2 or 15W-50 full synthetic
engine oil for track use.
For the LT5 engine, SAE 15W-50
full synthetic engine oil must be
used for track use, but after track
use must be changed back to
0W-40 dexos2 for street use.
Z51 Performance Package, Grand
Sport, Z06, and ZR1: Check the oil
level often during track events and
competitive driving and keep the
level at or near 0.5 L (0.5 qt) above
the upper mark that shows the
proper operating range on the
engine oil dipstick. After the
competitive driving, remove excess
oil so that the level on the dipstick is
not above the upper mark that
shows the proper operating range.

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. See Tires0265.
. 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 0198.
