Immobilizer Operation
The vehicle has a passive
theft-deterrent system.
The security light comes on in the
instrument cluster if there is a
problem with arming or disarming
the theft-deterrent system. This light
also comes on briefly when the
engine is started.
The system is automatically armed
when the ignition is turned off.
The immobilization system is
disarmed when the ignition is turned
on or placed in ACC/ACCESSORY
and a valid transmitter is found in
the vehicle.
You do not have to manually arm or
disarm the 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 ENGINE START/
STOP 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. Check the
fuse. See
Fuses0247. 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 eight RKE
transmitters can be programmed for
the vehicle. To program additional
transmitters, see
“Programming
Transmitters to the Vehicle” under
Remote Keyless Entry (RKE)
System Operation 027.
Do not leave the key or device that
disarms or deactivates the
theft-deterrent system in the vehicle.

98 Instruments and Controls
Caution
Leaving electrical equipment
plugged in for an extended period
of time while the vehicle is off will
drain the battery. Always unplug
electrical equipment when not in
use and do not plug in equipment
that exceeds the maximum
20 amp rating.
Certain electrical accessories may
not be compatible with the
accessory power outlet and could
overload vehicle or adapter fuses.
If a problem is experienced, see
your dealer.
When adding electrical equipment,
be sure to follow the proper
installation instructions included with
the equipment. See Add-On
Electrical Equipment 0210. It is recommended that a qualified
technician or dealer be seen for the
proper installation of your
equipment.
Caution
Hanging heavy equipment from
the power outlet can cause
damage not covered by the
vehicle warranty. The power
outlets are designed for
accessory power plugs only, such
as cell phone charge cords.
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.
Some warning lights come on briefly
when the engine is started to
indicate they are working. 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. Waiting to do
repairs can be costly and even
dangerous.

Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0227.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil (Except
Z06, Grand Sport, and Stingray
with Z51)
If the ENGINE OIL LOW–ADD OIL
message displays on the Driver
Information Center (DIC), check the
engine oil level right away.
Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview
0217 for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
Follow these guidelines:
. To get an accurate reading, park
the vehicle on level ground.
Check the engine oil level after
the engine has been off for at
least two hours. Checking the
engine oil level on steep grades
