Notice:Cranking the engine for
long periods of time, by pressing
the START button immediately
after cranking has ended, can
overheat and damage the
cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to allow the
cranking motor to cool down.
The vehicle has a
Computer-Controlled
Cranking System. This feature
assists in starting the engine
and protects components.
Once cranking has been initiated,
the engine continues cranking
for a few seconds or until the vehicle
starts. If the engine does not start,
cranking automatically stops after
15 seconds to prevent cranking
motor damage. To prevent gear
damage, this system also prevents
cranking if the engine is already
running. Notice:
The engine is designed
to work with the electronics in
the vehicle. If electrical parts
or accessories are added, you
could change the way the engine
operates. Before adding electrical
equipment, check with your
dealer. If you do not, the engine
might not perform properly. Any
resulting damage would not be
covered by the vehicle warranty.
Stopping the Engine
If the vehicle has an automatic
transmission, move the shift lever
to P (Park) and press and hold the
Acc. (Off/Accessory) button, located
on the instrument panel, until the
engine shuts off. If the shift lever
is not in P (Park), the engine shuts off and the vehicle goes into the
Accessory Mode. The DIC displays
SHIFT TO PARK. Once the shifter is
moved to P (Park), the vehicle turns
off. If the vehicle has a manual
transmission, it is recommended
that you move the shift lever to
R (Reverse) and set the parking
brake after you turn off the engine
by pressing and holding the Acc.
(Off/Accessory) button.
If the keyless access transmitter is
not detected inside the vehicle when
it is turned to off, the DIC displays
NO FOB
–OFF OR RUN?.

Driving and Operating 9-35
If driving safely on a wet road
and it becomes necessary to slam
on the brakes and continue braking
to avoid a sudden obstacle, a
computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling,
the computer will separately work
the brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decreasestopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Parking Brake
The parking brake lever is located to
the right of the center console.
To set the parking brake, hold the
brake pedal down. Pull the parking
brake lever up. If the ignition is on,
the brake system warning light will
come on.
To release the parking brake, hold
the brake pedal down. Then push
the release button in as you move
the parking brake lever all the
way down.
Notice:
Driving with the parking
brake on can overheat the brake
system and cause premature
wear or damage to brake system
parts. Make sure that the parking
brake is fully released and the
brake warning light is off before
driving.

foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
Cruise control will not work if the
parking brake is set, or if the master
cylinder brake fluid level is low.
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.

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.”
.Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil.”
.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.”

10-22 Vehicle Care
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer that
indicates when to change the
engine oil and filter. This is based
on engine revolutions and engine
temperature, and not on mileage.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably.
For the oil life system to work
properly, the system must be reset
every time the oil is changed.
Z06, ZR1, and Grand Sport models
have a racetrack‐ready dry sump
engine lubrication system. This
high‐performance system operates
differently than a standard engine
lubrication system and requires a
special procedure when changing
the engine oil and filter. SeeEngine
Oil on page 10‑15. When the system has calculated
that oil life has been diminished,
it indicates that an oil change is
necessary. A CHANGE ENGINE
OIL message comes on. Change
the oil as soon as possible within
the next 1 000 km (600 miles). It is
possible that, if driving under the
best conditions, the oil life system
might indicate that an oil change
is not necessary for up to a year.
The engine oil and filter must be
changed at least once a year and,
at this time, the system must be
reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 miles)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Press the TRIP button so
the OIL LIFE percentage is
displayed.
2. Press RESET and hold for two seconds. OIL LIFE
REMAINING 100% will appear.
If the CHANGE ENGINE OIL
message comes back on when the
vehicle is started, the engine oil life
system has not reset. Repeat the
procedure.

Front
.Brake pads can be visually
inspected through the wheel by
inspecting the outer brake pads
at each wheel.
.Brake pads should be replaced
when worn to two mm of pad
thickness. New pads are 10 mm
thick.
.In addition, brake pad inspection
is required any time the tires are
removed.
The ZR1 also has an electronic
brake pad wear sensor system.
When pads are worn, the CHANGE
BRAKE PADS message displays
in the Driver Information Center.
SeeBrake System Messages on
page 5‑36.
Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Brake linings should always be
replaced as complete axle sets. Brake Rotor Wear
ZR1 models have ceramic brake
rotors. Rotors should be visually
inspected whenever the brake pads
are replaced. Rotors also need to
be weighed before brake pads are
replaced to confirm that the rotor
mass is greater than the wear‐out
mass printed on the rotor. The rotor
can be reused if the weight of the
rotor is above the mass limit. Rotor
inspection and weighing methods
can be found in the service manual.

{WARNING
Rust or dirt on a wheel, or on the parts to which it is
fastened, can make wheel
nuts become loose after a
time. The wheel could come
off and cause a crash. When
you change a wheel, remove
any rust or dirt from places
where the wheel attaches to
the vehicle. In an emergency,
you can use a cloth or a paper
towel to do this; but be sure to
use a scraper or wire brush
later, if you need to, to get all
the rust or dirt off.Tightening Wheel Lug Nuts
{WARNING
Never use oil or grease on studs
or the threads of the wheel nuts.
If you do, the wheel nuts might
come loose and the wheel could
fall off, causing a crash.
{WARNING
Incorrect wheel nuts or improperly
tightened wheel nuts can cause
the wheel to become loose and
even come off. This could lead
to a crash. Be sure to use the
correct wheel nuts. If you have
to replace them, be sure to get
new GM original equipment
wheel nuts. Notice:
Improperly tightened
wheel nuts can lead to brake
pulsation and rotor damage.
To avoid expensive brake repairs,
evenly tighten the wheel nuts in
the proper sequence and to the
proper torque specification.
Tighten the wheel lug nuts firmly in
a crisscross sequence as shown.
