Service Electric Parking
Brake Light
The service electric parking brake
light should come on briefly when
starting the vehicle. If it does not
come on, have the vehicle serviced
by your dealer.
If this light stays on, there is a
problem with a system on the
vehicle that is causing the parking
brake system to work at a reduced
level. The vehicle can still be
driven, but should be taken to a
dealer as soon as possible. SeeElectric Parking Brake
0193.
A message may also display in the
Driver Information Center (DIC).
Antilock Brake System
(ABS) Warning Light
This light comes on briefly when the
engine is started.
If the light does not come on, have it
fixed so it will be ready to warn if
there is a problem.
If the light comes on while driving,
stop as soon as it is safely possible
and turn off the vehicle. Then start
the engine again to reset the
system. If the ABS light stays on,
or comes on again while driving, the
vehicle needs service. A chime may
also sound when the light comes on
steady. If the ABS light is the only light on,
the vehicle has regular brakes, but
the antilock brakes are not
functioning.
If both the ABS and the brake
system warning light are on, the
vehicle's antilock brakes are not
functioning and there is a problem
with the regular brakes. See your
dealer for service.

{Warning
The Data Link Connector (DLC) is
used for vehicle service and
Emission Inspection/Maintenance
testing. SeeMalfunction Indicator
Lamp 0111. A device connected
to the DLC —such as an
aftermarket fleet or
driver-behavior tracking device —
may interfere with vehicle
systems. This could affect vehicle
operation and cause a crash.
Such devices may also access
information stored in the vehicle’s
systems.
Caution
Some electrical equipment can
damage the vehicle or cause
components to not work and
would not be covered by the
vehicle warranty. Always check
with your dealer before adding
electrical equipment.
Add-on equipment can drain the
vehicle's 12-volt battery, even if the
vehicle is not operating.
The vehicle has an airbag system.

panel off the bracket.
Stingray Shown, Grand Sport and
Z06 Similar
2. Unscrew the two fasteners that secure the bracket.
3. Gently pull the bracket away from the grille.
To replace the bracket and aero
panel: 1. Position the bracket over the grille.
2. Secure the bracket by pushing the two fasteners into place. 3. Snap the aero panel into place.
Engine Overheating
The vehicle has several indicators
to warn of engine overheating.
There is an engine coolant
temperature gauge on the
instrument cluster. See
Engine
Coolant Temperature Gauge 0108.
The vehicle may also display a
message on the Driver Information
Center (DIC).
If the decision is made not to lift the
hood but to get service help right
away, see Roadside Assistance
Program 0325.
If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fan is running. If the engine
is overheating, the fan should be
running. If it is not, do not continue
to run the engine, and have the
vehicle serviced.
Caution
Do not run the engine if there is a
leak in the engine cooling system.
This can cause a loss of all
coolant and can damage the
system and vehicle. Have any
leaks fixed right away.
If Steam Is Coming from the
Engine
{Warning
Steam and scalding liquids from a
hot cooling system are under
pressure. Turning the pressure
cap, even a little, can cause them
to come out at high speed and
you could be burned. Never turn
the cap when the cooling system,
including the pressure cap, is hot.
Wait for the cooling system and
pressure cap to cool.

242 Vehicle Care
Caution (Continued)
.Do not mix water with
ready-to-use washer fluid.
Water can cause the
solution to freeze and
damage the washer fluid
tank and other parts of the
washer system.
. When using concentrated
washer fluid, follow the
manufacturer instructions for
adding water.
. Fill the washer fluid tank
only three-quarters full when
it is very cold. This allows
for fluid expansion if
freezing occurs, which could
damage the tank if it is
completely full.
Brakes
Brake Wear
Disc brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed. The sound can come and go or be
heard all the time the vehicle is
moving, except when applying the
brake pedal firmly.
{Warning
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Caution
Continuing to drive with worn-out
brake pads could result in costly
brake repair.
Under certain weather or operating
conditions, occasional brake squeal
might be heard with the vehicle's
performance braking system. This
brake system is designed for
superior fade resistance and
consistent operation using high performance brake pads. Brake
squeal is normal and does not affect
system performance.
If equipped with high performance
brake linings, there could be an
increased build-up of brake dust as
well as minor noises as compared
to standard brake linings.
Brake linings should always be
replaced as complete axle sets.
Brake Wear (Z06 and Grand Sport
with J57 Ceramic Brakes)
This vehicle does not have built-in
brake pad wear indicators. Periodic
visual inspection is required to
determine when to replace the
brake pads.
The Z06 and Grand Sport Coupe
with J57 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. Some driving conditions or
climates can cause a brake squeal
when the brakes are first applied or

low tire pressure warning light
flashes for about one minute and
then stays on for the remainder of
the ignition cycle. A DIC warning
message also displays. The
malfunction light and DIC warning
message come on at each ignition
cycle until the problem is corrected.
Some of the conditions that can
cause these to come on are:
.The TPMS sensor matching
process was not done or not
completed successfully. The
malfunction light and the DIC
message should go off after
successfully completing the
sensor matching process.
. One or more TPMS sensors are
missing or damaged. The
malfunction light and the DIC
message should go off when the
TPMS sensors are installed and
the sensor matching process is
performed successfully.
. Replacement tires or wheels do
not match the original equipment
tires or wheels. Tires and wheels
other than those recommended could prevent the TPMS from
functioning properly. See
Buying
New Tires 0272.
. Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning
properly, it cannot detect or signal a
low tire pressure condition. See
your dealer for service if the TPMS
malfunction light and DIC message
come on and stays on.
TPMS Sensor Matching
Process —Auto Learn
Function
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a new
tire/wheel position after rotating the
tires or replacing one or more of the
TPMS sensors. When a tire is
installed, the vehicle must be
stationary for about 20 minutes
before the system recalculates. The
following relearn process takes up
to 10 minutes, driving at a minimum speed of 19 km/h (12 mph).
A dash (-) or pressure value will
display in the DIC. See
Driver
Information Center (DIC) 0118.
A warning message displays in the
DIC if a problem occurs during the
relearn process.
Tire Inspection
We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected
for signs of wear or damage at
least once a month.
Replace the tire if:
.The indicators at three or
more places around the tire
can be seen.
.There is cord or fabric
showing through the tire's
rubber.
.The tread or sidewall is
cracked, cut, or snagged
deep enough to show cord or
fabric.
