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.

Immobilizer
SeeRadio Frequency Statement on
page 13‑21 for information
regarding Part 15 of the Federal
Communications Commission (FCC)
rules and Industry Canada
Standards RSS-GEN/210/220/310.
Immobilizer Operation
The vehicle has a passive
theft-deterrent system.
The system is automatically armed
when the ignition is turned off.
The immobilization system is
disarmed when the ignition is turned
to OFF/ACCESSORY or START and
a valid transmitter is found in the
vehicle.
You do not have to manually arm
or disarm the system.
The security light comes on if
there is a problem with arming or
disarming the theft-deterrent
system. The system has one or more RKE
transmitters that are matched to an
immobilizer control unit in the
vehicle. Only a correctly matched
RKE transmitter starts the vehicle.
The vehicle may not start if the
RKE transmitter is damaged.
If the engine does not start and the
security light comes on, there may
be a problem with the immobilizer
system. Press the START button
again.
If the vehicle does not start and the
RKE transmitter appears to be
undamaged, try another RKE
transmitter. Or, place the transmitter
in the transmitter pocket. See
“NO
FOBS DETECTED” underKey and
Lock Messages on page 5‑43 for
additional information. Check the
fuse. See Fuses and Circuit
Breakers on page 10‑51. If the
engine still does not start with the
other transmitter, the vehicle needs
service. If the engine does start, the
first transmitter may be faulty. See your dealer or have a new RKE
transmitter programmed to the
vehicle.
The immobilizer system can learn
new or replacement RKE
transmitters. Up to four RKE
transmitters can be programmed for
the vehicle. To program additional
transmitters, see
“Matching
transmitter(s) to Your Vehicle” under
Remote Keyless Entry (RKE)
System Operation on page 2‑3.
Do not leave the key or device
that disarms or deactivates the
theft-deterrent system in the vehicle.

WARNING (Continued)
Even if the vehicle appears to be
drivable after a moderate crash,
there may be concealed damage
that could make it difficult to
safely operate the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.
Additional windshield breakage may
also occur from the front outboard
passenger airbag.
.Airbags are designed to inflate
only once. After an airbag
inflates, you will need some
new parts for the airbag system.
If you do not get them, the
airbag system will not be there
to help protect you in another
crash. A new system will include
airbag modules and possibly other parts. The service manual
for the vehicle covers the need
to replace other parts.
.The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. See
Vehicle Data
Recording and Privacy on
page 13‑20 andEvent Data
Recorders on page 13‑20.
.Let only qualified technicians
work on the airbag system.
Improper service can mean that
the airbag system will not work
properly. See your dealer
for service.
Passenger Sensing
System
The vehicle has a passenger
sensing system for the front
outboard passenger position. The
passenger airbag status indicator
will light in the rearview mirror when
the vehicle is started.
United States
Canada and Mexico
The words ON and OFF, or the
symbol for on and off, will be visible
during the system check. When the
system check is complete, either the
word ON or OFF, or the symbol for
on or off, will be visible. See
Passenger Airbag Status Indicator
on page 5‑18.

5-8 Instruments and Controls
Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the engine is started
to indicate they are working.Gauges can indicate when there
could be a problem with a vehicle
function. Often gauges and warning
lights work together to indicate a
problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gauges
shows there may be a problem,
check the section that explains what
to do. Follow this manual's advice.
Waiting to do repairs can be costly
and even dangerous.

{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule for changing engine oil.
The engine oil pressure gauge
shows the engine oil pressure
in kPa (kilopascals) or psi (pounds
per square inch) when the engine
is running.
Oil pressure should be 140 to
550 kPa (20 to 80 psi). In certain
situations such as long, extended
idles on hot days, it could read as
low as 40 kPa (6 psi) and still be
considered normal.

Instruments and Controls 5-17
Voltmeter Gauge
Base and Z06, Metric and English
The voltmeter shows the voltage
output of the battery. It shows the
voltage output of the charging
system while the engine is running. The reading changes as the rate of
charge changes (with engine speed,
for example), but if the voltmeter
reads at 9 volts or below, the
instrument panel cluster and other
systems may shut down. The Driver
Information Center (DIC) reads
BATTERY VOLTAGE LOW when
the vehicle is at 10 volts or below.
Have it checked right away. Driving
with the voltmeter reading at
10 volts or below could drain the
battery and disable the vehicle.
Safety Belt Reminders
When the engine is started, this light
flashes and a chime may come on
to remind the driver to fasten their
safety belt. Then the light stays on
solid until the belt is buckled.
This cycle may continue several
times if the driver remains or
becomes unbuckled while the
vehicle is moving.
If the driver safety belt is buckled,
neither the light nor the chime
comes on.

5-18 Instruments and Controls
Airbag Readiness Light
The system checks the airbag's
electrical system for possible
malfunctions. If the light stays on
it indicates there is an electrical
problem. The system check
includes the airbag sensor(s),
the passenger sensing system, the
pretensioners, the airbag modules,
the wiring, and the crash sensing
and diagnostic module. For more
information on the airbag system,
seeAirbag System on page 3‑15.
The airbag readiness light flashes
for a few seconds when the engine
is started. If the light does not come
on then, have it fixed immediately.
{WARNING
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in
the vehicle might not inflate in a
crash, or they could even inflate
without a crash. To help avoid
injury, have the vehicle serviced
right away.
If there is a problem with the airbag
system, an airbag Driver Information
Center (DIC) message can also
come on. See Vehicle Messages on
page 5‑36 for more information.
Passenger Airbag Status
Indicator
The vehicle has the passenger
sensing system. See Passenger
Sensing System on page 3‑21 for
important safety information. The
rearview mirror has a passenger
airbag status indicator.
