{WARNING
If the HUD image is too bright,
or too high in your field of view, it
may take you more time to see
things you need to see when it is
dark outside. Be sure to keep the
HUD image dim and placed low in
your field of view.
For vehicles with the Head-Up
Display (HUD), you can see some
of the driver information that
appears on the instrument panel
cluster. The information may be displayed in
English or metric units and appears
as an image focused out toward the
front of the vehicle. The HUD
consists of the following information:
.Speedometer
.Turn Signal Indicators
.High-Beam Indicator Symbol
.Tachometer
.Manual Paddle Shift Gear
Indicator (If Equipped)
These displays on the HUD are
for use when using the manual
paddle shift controls to shift the
transmission. See
“Manual
Paddle Shift” inAutomatic
Transmission on page 9‑25.
.Shift Light
This light is used for
performance driving to indicate
that the vehicle's best
performance level has been
reached to shift the transmission
into the next higher gear. An
arrow pointing up will light up on the display just prior to reaching
the engine fuel cut-off mode.
This cut-off is about 6,500 rpm
for the LS3 engine, 6,600 rpm
for the LS9 & ZR1 engines, and
7,000 rpm for the LS7 engine.

temperature to be higher than
normal. If this message appears,
you may continue to drive at a
slower speed. Monitor the
transmission fluid temperature and
allow it to cool to at least 110°C
(230°F). The transmission fluid
temperature can be monitored with the gauges button on the DIC. See
“DIC Operation and Displays”
under

Air Vents
Use the tab located on the air
outlets to change the direction of the
airflow.
Operation Tips
.Clear away any ice, snow,
or leaves from the air inlets at
the base of the windshield that
may block the flow of air into the
vehicle.
.Use of non-GM approved hood
deflectors may adversely affect
the performance of the system.
.Keep the area around the base
of the instrument panel console
and air path under the seats
clear of objects to help circulate
the air inside of the vehicle more
effectively.
Maintenance
Passenger Compartment
Air Filter
The passenger compartment air
filter removes certain particles from
the air including pollen and dust
particles. Reductions in airflow,
which may occur more often in
dusty areas, indicate that the filter
may need to be replaced. See
Maintenance Schedule on
page 11‑3.
Notice:Driving without a
passenger compartment air filter
in place can cause water and
small particles, like paper and
leaves, to be pulled into your
climate control system which may
cause damage to it. Make sure
you always replace the old filter
with a new one. The passenger compartment air
filter is located on the passenger
side of the engine compartment
near the battery. See
Engine
Compartment Overview on
page 10‑8.
To check or replace the air filter:
1. Remove the cover retainer clips (A) from the passenger
compartment air filter cover.
2. Remove the cover.

9-6 Driving and Operating
Remember: Antilock brakes help
avoid only the braking skid.
Racing or Other
Competitive Driving
Racing or competitive driving may
affect the vehicle warranty. See the
warranty book before using the
vehicle for racing or other
competitive driving.
Notice: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 Oil on
page 10‑13.
Z06, ZR1, manual transmission
Grand Sport Coupe and 427
Convertible only: 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. Except Z06, ZR1, manual
transmission Grand Sport Coupe
and 427 Convertible : Be sure to
check the oil level often during
racing or other competitive
driving and keep the level at or
near 1 L (1 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.
Z06, ZR1, manual transmission
Grand Sport Coupe and 427
Convertible Only: For racing 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.
Z06, ZR1, and manual transmission
Grand Sport Coupe Only: For racing
or competitive driving, it is
recommended that the loading of
the vehicle be limited to the driver
only, with no other cargo, and that
tires be inflated to 180 kPa (26 psi)
for a maximum speed of 230 km/h
(143 mph).
If the vehicle is a Z06, ZR1,
or manual transmission Grand Sport
Coupe and 427 Convertible model,
it has greaseable outer ends on
both of the rear toe-links. Under
normal use, lubrication should be
performed as described in the
maintenance schedule. See
Maintenance Schedule on
page 11‑3
andRecommended
Fluids and Lubricants on
page 11‑12. If using the vehicle for
racing, lubrication should be
performed at the end of each racing
day. See your dealer for lubrication
and make sure any needed repairs
are made at once. Proper
procedures for performing these
