1-22 In Brief
The vehicle has an Active Handling
System that helps maintain
directional control of the vehicle in
difficult driving conditions. See
Active Handling System on
page 9‑38.
The vehicle may have Competitive
Driving Mode (except ZR1),
Performance Traction
Management (Z06, ZR1), and
Launch Control systems designed to
allow increased performance while
accelerating and cornering. See
Competitive Driving Mode on
page 9‑39.Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS warning light alerts you
to a significant loss in pressure of
one of the vehicle's tires. If the
warning light comes on, stop as
soon as possible and inflate the
tires to the recommended pressure
shown on the Tire and Loading
Information label. SeeVehicle Load
Limits on page 9‑14. The warning
light will remain on until the tire
pressure is corrected.
During cooler conditions, the low tire
pressure warning light may appear
when the vehicle is first started and
then turn off. This may be an early indicator that the tire pressures are
getting low and the tires need to be
inflated to the proper pressure.
The TPMS does not replace normal
monthly tire maintenance. It is the
driver
’s responsibility to maintain
correct tire pressures.
See Tire Pressure Monitor System
on page 10‑68.Z06, Z16, and ZR1
Features
Checking Engine Oil
Z06, ZR1, and manual transmission
Z16 (Grand Sport) coupe models
have a high performance dry sump
lubrication system. This system
operates differently than a standard
engine lubrication system. See
Engine Oil on page 10‑16.
You should check the oil level only
after the engine has been
thoroughly warmed up and then
shut off for at least five minutes.
This ensures that the oil level
reading obtained will be accurate.

Boost Gauge (ZR1)
Metric
EnglishThis gauge indicates vacuum during
light to moderate throttle and boost
under heavier throttle.
It displays the air pressure level in
the intake manifold before it enters
the engine's combustion chamber.
The gauge is automatically centered
at zero every time the engine is
started. Actual vacuum or boost is
displayed from this zero point.
Changes in ambient pressure, such
as driving in mountains and
changing weather, will slightly
change the zero reading.

9-6 Driving and Operating
Defensive drivers avoid most skids
by taking reasonable care suited to
existing conditions, and by not
overdriving those conditions.
But skids are always possible.
If the vehicle starts to slide, follow
these suggestions:
.Ease your foot off the
accelerator pedal and quickly
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.
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 10‑16. Z06, ZR1, and Grand Sport Coupe
manual transmission 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, and Grand Sport
Coupe manual transmission:
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, and Grand Sport Coupe
manual transmission 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

10-16 Vehicle Care
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:
.Always 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. See Engine Oil
Life System on page 10‑22.
.Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
(Except Z06, ZR1, and
Grand Sport)
If the CHECK OIL LEVEL message
displays on the Driver Information
Center (DIC), check the engine oil
level right away. For more
information, see Engine Oil
Messages on page 5‑41. Check the
engine oil level regularly; this is an
added reminder.
It is a good idea to check the
engine oil level at each fuel fill.
In order to get an accurate reading,
the vehicle must be on level ground.
The engine oil dipstick handle
is a yellow loop. See Engine
Compartment Overview on
page 10‑10 for the location of the
engine oil dipstick. Obtaining an accurate oil level
reading is essential:
1. If the engine has been running
recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.
2. Pull the dipstick and clean it with a paper towel or cloth, then push
it back in all the way. Remove it
again, keeping the tip down, and
check the level.

Vehicle Care 10-17
When to Add Engine Oil
(Except Z06, ZR1, and Grand
Sport)
If the oil is below the cross-hatched
area at the tip of the dipstick, add
1 L (1 qt) of the recommended oil
and then recheck the level. See
“Selecting the Right Engine Oil”in
this section for an explanation of
what kind of oil to use. For engine
oil crankcase capacity, see
Capacities and Specifications on
page 12‑2.
See Racing or Other Competitive
Driving on page 9‑6 for additional
information on engine oil. Notice:
Do not add too much oil.
Oil levels above or below the
acceptable operating range
shown on the dipstick are harmful
to the engine. If you find that you
have an oil level above the
operating range, i.e., the engine
has so much oil that the oil level
gets above the cross-hatched
area that shows the proper
operating range, the engine could
be damaged. You should drain
out the excess oil or limit driving
of the vehicle and seek a service
professional to remove the
excess amount of oil.
See Engine Compartment Overview
on page 10‑10 for the location of the
engine oil fill cap.
Add enough oil to put the level
somewhere in the proper operating
range . Push the dipstick all the way
back in when through.
