The vehicle is automatically
immobilized when the transmitter
leaves the vehicle.
The immobilization system is
disarmed when ENGINE START/
STOP is pressed and a valid
transmitter is found in the vehicle.
The security light in the instrument
cluster comes on when there is a
problem with arming or disarming
the theft-deterrent system.
The system has one or more
transmitters matched to an
immobilizer control unit in your
vehicle. Only a correctly matched
transmitter will start the vehicle.
If the transmitter is ever damaged,
you may not be able to start your
vehicle.
When trying to start the vehicle, the
security light comes on briefly when
the ignition is turned on.If the engine does not start and the
security light stays on, there is a
problem with the system. Turn the
vehicle off and try again.
If the vehicle will not change ignition
modes (ACC/ACCESSORY, on, off),
and the RKE transmitter appears to
be undamaged, try another
transmitter. Or, you may try placing
the transmitter in the front
cupholder. See
“Starting the Vehicle
with a Low Transmitter Battery”
under Remote Keyless Entry (RKE)
System Operation 08.
If the engine does not start with the
other transmitter or when the
transmitter is in the pocket in the
front cupholder, the vehicle needs
service. See your dealer who can
service the theft-deterrent system
and have a new transmitter
programmed to the vehicle.
Do not leave the transmitter 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.

049.
Position the release button on
the buckle so that the seat belt
could be quickly unbuckled if
necessary.

later in this section for
instructions on use and
important safety information.
