Immobilizer
SeeRadio Frequency Statement 0290.
Immobilizer Operation
This vehicle has a passive theft-deterrent
system.
The system does not have to be manually
armed or disarmed.
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”
underRemote Keyless Entry (RKE)
System Operation 07.
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.

{Warning
Sitting in a reclined position when the

Even when buckled up, the seat belts
cannot do their job.
The shoulder belt will not be against
your body. Instead, it will be in front of
you. In a crash, you could go into it,
receiving neck or other injuries.
The lap belt could go up over your
abdomen. The belt forces would be there,
not at your pelvic bones. This could cause
serious internal injuries.
For proper protection when the vehicle is
in motion, have the seatback upright.
Then sit well back in the seat and wear
the seat belt properly.
Do not have a seatback reclined if the
vehicle is moving.
