Fuel
Use of the recommended fuel
is an important part of the proper
maintenance of this vehicle. To help
keep the engine clean and maintain
optimum vehicle performance, we
recommend the use of gasoline
advertised as TOP TIER Detergent
Gasoline.
Look for the TOP TIER label on the
fuel pump to ensure gasoline meets
enhanced detergency standards
developed by auto companies. A list
of marketers providing TOP TIER
Detergent Gasoline can be found at
www.toptiergas.com.
The eighth digit of the Vehicle
Identification Number (VIN) shows
the code letter or number that
identifies the vehicle's engine.
The VIN is at the top left of the
instrument panel. SeeVehicle
Identification Number (VIN) on
page 12‑1.
Recommended Fuel
If the vehicle has the 6.2L V8 engine
(VIN Code W), use premium
unleaded gasoline with a posted
octane rating of 91 or higher. You
can also use regular unleaded
gasoline rated at 87 octane or
higher, but the vehicle's acceleration
could be slightly reduced, and a
slight audible knocking noise,
commonly referred to as spark
knock, might be heard. If the octane
is less than 87, a heavy knocking
noise might be heard when driving.
If this occurs, use a gasoline rated
at 87 octane or higher as soon as
possible. Otherwise, you could
damage the engine. If heavy
knocking is heard when using
gasoline rated at 87 octane or
higher, the engine needs service.

{WARNING
If a fire starts while you are
refueling, do not remove the
nozzle. Shut off the flow of fuel by
shutting off the pump or by
notifying the station attendant.
Leave the area immediately.
Notice: If you need a new fuel
cap, be sure to get the right type.
Your dealer can get one for you.
If you get the wrong type, it may
not fit properly. This may cause
the malfunction indicator lamp to
light and may damage the fuel
tank and emissions system. See
Malfunction Indicator Lamp on
page 5‑19.
Filling a Portable Fuel
Container
{WARNING
Never fill a portable fuel container
while it is in the vehicle. Static
electricity discharge from the
container can ignite the fuel
vapor. You can be badly burned
and the vehicle damaged if this
occurs. To help avoid injury to
you and others:
.Dispense fuel only into
approved containers.
.Do not fill a container while it
is inside a vehicle, in a
vehicle's trunk, pickup bed,
or on any surface other than
the ground.
(Continued)
WARNING (Continued)
.Bring the fill nozzle in contact
with the inside of the fill
opening before operating the
nozzle. Contact should be
maintained until the filling is
complete.
.Do not smoke while
pumping fuel.
.Do not use a cellular phone
while pumping fuel.

Engine Air Cleaner/Filter
SeeEngine Compartment Overview
on page 10‑10 for the location of the
engine air cleaner/filter.
Notice: If you spray water into
the engine air cleaner/filter intake
and water enters the engine air
cleaner/filter housing, you could
damage your vehicle's engine.
The repairs would not be covered
by your warranty. Do not spray
water into the engine air cleaner/
filter intake and/or housing.
If cleaning the vehicle with the hood
open, take care not to spray water
directly near the filter opening of
the air cleaner, as shown in the
illustration, as this could damage
the vehicle's engine. When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/filter at
the scheduled maintenance
intervals and replace them at
the first oil change after each
80 000 km (50,000 mi) interval.
See
Maintenance Schedule on
page 11‑3 for more information.
If driving in dusty/dirty conditions,
inspect the filter at each engine oil
change.
How to Inspect the Engine
Air Cleaner/Filter
To inspect the air cleaner/filter,
remove the filter from the vehicle
and lightly shake the filter to release
loose dust and dirt. If the filter
remains covered with dirt, a new
filter is required. To inspect or replace the engine air
cleaner/filter:
1. Open the hood. See
Hood on
page 10‑9.

Overheated Engine
Protection
Operating Mode
This emergency operating mode
lets the vehicle be driven to a safe
place, up to 80 km (50 mi), in an
emergency situation. If an
overheated engine condition exists
and the messages COOLANT
OVER TEMPERATURE and
REDUCED ENGINE POWER are
displayed, along with the check
engine light, an overheat protection
mode which alternates firing groups
of cylinders helps prevent engine
damage. In this mode, there is a
significant loss in power and engine
performance.Driving extended distances in the
overheat protection mode should
be avoided.
Notice:
After driving in the
overheated engine protection
operating mode, to avoid engine
damage, allow the engine to cool
before attempting any repair.
The engine oil will be severely
degraded. Repair the cause of
coolant loss, change the oil
and reset the oil life system.
See Engine Oil on page 10‑16.
Power Steering Fluid
SeeEngine Compartment Overview
on page 10‑10 for reservoir location.
When to Check Power Steering
Fluid
It is not necessary to regularly
check power steering fluid unless
there is a leak suspected in the
system or an unusual noise is
heard. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.

Vehicle Care 10-39
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 Wear (ZR1, Z06, and
Grand Sport Only)
The ZR1, Z06, and Grand Sport
models do not have built-in brake
pad wear indicators and periodic
visual inspection of the brake pads
is required to determine when to
replace the brake pads.Notice:
Continuing to drive with
worn-out brake pads could result
in costly brake repair.
.Make sure that the brakes have
been given sufficient time to cool
and then set the park brake.
Rear
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 2 mm of pad
thickness. New pads are
10 mm thick.
.In addition, brake pad inspection
is required any time the tires are
removed.

Black plate (40,1)Chevrolet Corvette Owner Manual - 2012
10-40 Vehicle Care
The ZR1, Z06, and Grand Sport
models also have 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 5‑37.
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, and Z06 and
Grand Sport models may 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. See
Service
Publications Ordering Information
on page 13‑17. Brake Rotor Protector
{WARNING
Ceramic rotors will be very hot
after operation and touching them
may cause burns. Be sure brake
system is completely cool prior to
installation of protector, or coming
in contact with them.
Notice: Rotors may be chipped if
hard contact is made with the
wheel during wheel installation or
removal. Always use the rotor
protectors. Be sure to carefully
follow wheel removal and
installation instructions.

Headlamp Aiming
Headlamp aim has been preset at
the factory and should need no
further adjustment.
However, if the vehicle is damaged
in a crash, the headlamp aim may
be affected. Aim adjustment to the
low-beam headlamps may be
necessary if oncoming drivers flash
their high-beam headlamps at you
(for vertical aim).
If the headlamps need to be
re-aimed, it is recommended that
the vehicle be taken to the dealer
for service.
Bulb Replacement
For the proper type of replacement
bulbs, seeReplacement Bulbs on
page 10‑50.
For any bulb‐changing procedure
not listed in this section, contact
your dealer.
Halogen Bulbs
{WARNING
Halogen bulbs have pressurized
gas inside and can burst if you
drop or scratch the bulb. You or
others could be injured. Be sure
to read and follow the instructions
on the bulb package.
High Intensity Discharge
(HID) Lighting
{WARNING
The low beam high intensity
discharge lighting system
operates at a very high voltage.
If you try to service any of the
system components, you could be
seriously injured. Have your
dealer or a qualified technician
service them.
The vehicle may have HID
headlamps. After an HID headlamp
bulb has been replaced, you may
notice that the beam is a slightly
different shade than it was originally.
This is normal.
