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.
SeeEngine Oil on page 10‑14.
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. Jump Starting the Battery
The battery of Z06, ZR1, and
manual transmission Z16 (Grand
Sport) coupe models is in the rear
of the vehicle. You do not need to
access the battery for jump starting.
There are remote positive (+) and
negative (−) terminals under the
hood for this purpose. See
Battery
on page 10‑40 andJump Starting
on page 10‑78.
Brake Noise
Under certain weather or operating
conditions, occasional brake noise
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
noise is normal and does not affect
system performance. See Braking
on page 9‑4. Car Wash Guidelines
Automatic car washes are not
recommended for this vehicle.
Some car washes cause damage to
the vehicle, the wheels, and the
convertible top, if the vehicle is so
equipped.
If you drive the vehicle through an
automatic car wash that does not
have enough clearance for the
undercarriage and/or wide rear tires
and wheels, you could damage the
vehicle. Verify with the manager of
the car wash that the vehicle will fit
before entering the car wash or use
a touchless car wash. See
“Washing
Your Vehicle” underExterior Care
on page 10‑82.

5. Reach through the open windowand manually pull the release
lever on the floor.
6. Press the unlock button on the transmitter to turn off the alarm.
If the alarm does not sound, check
to see if the horn works. The horn
fuse may be blown. See Fuses and
Circuit Breakers on page 10‑47.
If the horn works, but the alarm
does not go off, see your dealer.
Disarming the System
Press the unlock button on the RKE
transmitter or squeeze the door
handle sensor while the transmitter
is near the vehicle to unlock a door.
Unlocking a door any other way sets
off the alarm. If the alarm sounds,
press the unlock button on the RKE
transmitter to disarm it.
Do not leave the key or device
that disarms or deactivates the
theft-deterrent system in the vehicle.
Immobilizer
See Radio 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”
under Key and Lock Messages on
page 5‑42 for additional information.
Check the fuse. See Fuses and
Circuit Breakers on page 10‑47.

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”underRemote 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.Exterior Mirrors
Convex Mirrors
{WARNING
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the right lane,
you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.
Power Mirrors
To adjust the mirrors:
1. Press
}or|to select a mirror.
2. Press the control pad to adjust the mirror.
3. Return the switch to the center to deselect the mirror.
If the vehicle has the memory
feature, a preferred mirror position
can be stored. See Memory Seats
on page 3‑4.

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. Driving with the engine
oil low can also damage the
engine. The repairs would not be
covered by the vehicle warranty.
Check the oil level as soon as
possible. Add oil if required,
but if the oil level is within the
operating range and the oil
pressure is still low, have the
vehicle serviced. 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. Oil pressure
may exceed 689 kPa (100 psi)
when first started or when
accelerating. It may vary with
engine speed, outside temperature
and oil viscosity, but readings above
the shaded area show the normal
operating range. Readings in the
shaded area tell you that the engine
is low on oil, or that you might have
some other oil problem. See
Engine
Oil on page 10‑14.
The engine oil pressure can also
be displayed using the GAGES
button on the Driver Information
Center (DIC). See Driver Information
Center (DIC) on page 5‑26.

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
Safety Belt Reminder Light
When the engine is started, a chime
sounds for several seconds to
remind a driver to fasten the safety
belt, unless the driver safety belt is
already buckled.
The safety belt light comes on and
stays on for several seconds, then
flashes for several more.
This chime and light are repeated if
the driver remains unbuckled and
the vehicle is in motion. If the driver
safety belt is already buckled,
neither the chime nor the light
comes on.
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), 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 5‑35 for more information.

Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors the operation
of the vehicle to ensure emissions
are at acceptable levels, to produce
a cleaner environment. This light
comes on when the vehicle is
placed in Service Only Mode, as a
check to show it is working. If it
does not, have the vehicle serviced
by your dealer. SeeIgnition
Positions on page 9‑20 for more
information.
If the malfunction indicator lamp
comes on and stays on while the
engine is running, this indicates that
there is an OBD II problem and
service is required. Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system assists
the service technician in correctly
diagnosing any malfunction.
Notice:
If the vehicle is
continually driven with this light
on, the emission controls might
not work as well, the vehicle fuel
economy might not be as good,
and the engine might not run as
smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.
Notice: Modifications made to
the engine, transmission,
exhaust, intake, or fuel system
of the vehicle or the replacement
of the original tires with other
than those of the same Tire
Performance Criteria (TPC) can
affect the vehicle's emission
controls and can cause this light
to come on. Modifications to these systems could lead to
costly repairs not covered
by the vehicle warranty.
This could also result in a
failure to pass a required
Emission Inspection/Maintenance
test. See
Accessories and
Modifications on page 10‑3.
This light comes on during a
malfunction in one of two ways:
Light Flashing: A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
The following can prevent more
serious damage to the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
