start to have the vehicle in view when doing
so. Check local regulations for any
requirements on remote starting of vehicles. Do not use the remote start feature if the
vehicle is low on fuel. The vehicle could run
out of fuel.

the lens.
Vehicle Security
This vehicle has theft-deterrent features;
however, they do not make the vehicle
impossible to steal.

This vehicle has an anti-theft alarm system.
The indicator light, on the instrument panel
near the windshield, indicates the status of
the system.

How to Detect a Tamper Condition
IfKis pressed and the horn chirps and the
lights flash three times, the alarm was
activated while the alarm system was
armed.
If the alarm system has been activated, a
message will appear on the DIC.
Immobilizer
See Radio Frequency Statement 0335.
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 vehicle is turned off.
The immobilization system is disarmed
when the ignition is on or in accessory
mode and a valid transmitter is present in
the vehicle.
The security light in the instrument cluster
comes on if there is a problem with arming
or disarming the theft-deterrent system.
The system has one or more RKE
transmitters matched to an immobilizer
control unit in the vehicle. Only a correctly
matched RKE transmitter will start the
vehicle. If the transmitter is ever damaged,
the vehicle may not start. When trying to start the vehicle, the
security light may come 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 ignition off and try again.
If the vehicle will not change ignition
modes, and the RKE transmitter appears to
be undamaged, try another transmitter. Or,
try placing the transmitter in the
transmitter pocket located in the center
console. See Starting the Vehicle With a Low
Transmitter Battery under
Remote Key
Operation (Mechanical Key) 010 or
Remote Key Operation (Remote Key) 013.
If the ignition mode will not change with
the other transmitter or with a transmitter
in the transmitter pocket, the vehicle needs
service. If the ignition does change modes,
the first transmitter may be faulty. See a
dealer who can service the theft-deterrent
system and have a new RKE transmitter
programmed to the vehicle.
It is possible for the immobilizer system
to learn new or replacement RKE
transmitters. Up to eight transmitters can be
programmed for the vehicle. To program
additional transmitters, see Programming

object toward a person. This could cause
severe injury or even death. Secure
objects away from the area in which an
airbag would inflate.

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.

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 052.
The airbag readiness light comes on for
several seconds when the vehicle 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, a Driver Information Center (DIC)
message may also come on.
Passenger Airbag Status Indicator
The vehicle has a passenger sensing system.
See
Passenger Sensing System 058. The
overhead console has a passenger airbag
status indicator.
United States
Canada
When the vehicle is started, the passenger
airbag status indicator will light ON and OFF,
or the symbol for on and off, for several
seconds as a system check. Then, after several more seconds, the status indicator
will light either ON or OFF, or either the on
or off symbol, to let you know the status of
the front outboard passenger frontal airbag
and knee airbag.
If the word ON, or the on symbol, is lit on
the passenger airbag status indicator, it
means that the front outboard passenger
frontal airbag and knee airbag are allowed
to inflate.
If the word OFF, or the off symbol is lit, on
the airbag status indicator, it means that
the passenger sensing system has turned off
the front outboard passenger frontal airbag
and knee airbag.
If, after several seconds, both status
indicator lights remain on, or if there are no
lights at all, there may be a problem with
the lights or the passenger sensing system.
See your dealer for service.
{Warning
If the airbag readiness light ever comes
on and stays on, it means that
something may be wrong with the airbag
system. To help avoid injury to yourself
or others, have the vehicle serviced right
