impact sensors, or airbag wiring.
Your dealer and the service manual
have information about the location
of the airbag sensors, sensing and
diagnostic module, and airbag
wiring.
In addition, the vehicle has a
passenger sensing system for the
front outboard passenger position,
which includes sensors that are part
of the passenger seat. The
passenger sensing system may not
operate properly if the original seat
trim is replaced with non-GM

designed for a different vehicle. Any
object, such as an aftermarket seat
heater or a comfort-enhancing pad
or device, installed under or on top
of the seat fabric, could also
interfere with the operation of the
passenger sensing system. This
could either prevent proper
deployment of the passenger
airbag(s) or prevent the passengersensing system from properly
turning off the passenger airbag(s).

Automatic Headlamp
System
When the exterior lamp control is
set to AUTO and it is dark enough
outside, the headlamps and parking
lamps come on automatically.
There is a light sensor on top of the
instrument panel. Do not cover the
sensor, otherwise the headlamps
will come on when they are not
needed.
The system may also turn on the
headlamps and parking lamps when
driving through a parking garage or
tunnel.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it
is light outside when the vehicle
leaves the garage, there is a slight
delay before the automatic
headlamp system changes to the
DRL. During that delay, the

Sensors
The interior cabin air temperature
and solar sensor on top of the
instrument panel near the
windshield monitors the solar heat
and measures the initial interior
cabin temperature. The climate control system uses the
sensor information to adjust the
temperature, fan speed,
recirculation, and air delivery mode
for best comfort.
The humidity and windshield
temperature sensor is on the
windshield glass inside surface near
the rearview mirror. The automatic
climate control system uses this
sensor to receive information to
determine the need for defogging.
If any of these sensors are blocked
or covered, the automatic climate
control system may not work
properly.
There is also a sensor behind the
front bumper. This sensor reads the
outside air temperature and helps to
maintain the temperature inside the
vehicle. Any cover on the front of
the vehicle could give a false
reading in the temperature.

Limited-Slip Differential
(Stingray without
Z51 Only)
If equipped, the mechanical
limited-slip differential can give more
traction on snow, mud, ice, sand,
or gravel. It works like a standard
axle most of the time, but when
traction is low, this feature allows
the drive wheel with the most
traction to move the vehicle. For
vehicles with limited-slip differential,
driven under severe conditions, the
rear axle fluid should be changed.

0 201 andMaintenance Schedule
0 304.
Limited-Slip Differential
(Z06, Grand Sport, and
Stingray with Z51)
If equipped, the Electronic
Limited-Slip Differential (eLSD) is
automatically activated. eLSD
actively monitors vehicle sensors
and driver inputs to determine the
amount of change for the
conditions. With eLSD, the
vehicle has:
.
Enhanced high-speed control
. Improved traction through
corners, allowing more
acceleration
. More precise steering
. Increased vehicle agility
. Integration with StabiliTrak
For vehicles with eLSD, driven
under severe conditions, the rear
axle fluid should be changed.
See Competitive Driving Mode
0 201 andMaintenance Schedule

Cruise Control
With cruise control, a speed of
about 40 km/h (25 mph) or more
can be maintained without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
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.
If equipped with a manual
transmission, the cruise control will
remain active when the gears are
shifted. The cruise is disengaged if
the clutch is pressed for several
seconds.

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

drive over 80 km/h (50 mph) when
the low tire warning light is
displayed. Drive cautiously and
check the tire pressures as soon
as possible.
Run-flat tires can be driven on with
no air pressure. There is no need to
stop on the side of the road to
change the tire. Continue driving;
however, do not drive too far or too
fast. Driving on the tire may not be
possible if there is permanent
damage. To prevent permanent
damage, the tire can be driven with
no air pressure for up to 80 km
(50 mi) at speeds slower than
80 km/h (50 mph). As soon as
possible, contact the nearest
authorized GM or run-flat servicing
facility for inspection and repair or
replacement.
When driving on a deflated run-flat
tire, avoid potholes and other road
hazards that could damage the tire
and/or wheel beyond repair. When a tire has been damaged, or if driven
any distance while deflated, check
with an authorized run-flat tire
service center to determine whether
the tire can be repaired or should be
replaced. To maintain the run-flat
feature, all replacement tires must
be run-flat tires.
To locate the nearest GM or run-flat
servicing facility, call Customer
Assistance.
The valve stems on run-flat tires
have sensors that are part of the
TPMS. See
Tire Pressure Monitor
System 0267. These sensors
contain batteries that are designed
to last for 10 years under normal
driving conditions. See your dealer
for wheel or sensor replacement.

Low-Profile Tires
Low-Profile Performance Tires
The original equipment tires on
this vehicle are classified as
low-profile performance tires.
These tires are designed for
very responsive driving on wet
or dry pavement; however, they
may produce more road noise
and tend to wear faster.
Caution
Low-profile tires are more
susceptible to damage from road
hazards or curb impact than
standard profile tires. Tire and/or
wheel assembly damage can
occur when coming into contact (Continued)
