Leaving children in a vehicle with the
ignition key is dangerous and children or
others could be seriously injured or killed.
They could operate the power windows
or other controls or make the vehicle

{Warning
If the key is unintentionally rotated while
the vehicle is running, the ignition could
be moved out of the RUN position.
This could be caused by heavy items
hanging from the key ring, or by large or
long items attached to the key ring that
could be contacted by the driver or
steering wheel. If the ignition moves out
of the RUN position, the engine will shut
off, braking and steering power assist
may be impacted, and airbags may not
deploy. To reduce the risk of
unintentional rotation of the ignition key,
do not change the way the ignition key
and Remote Keyless Entry (RKE)
transmitter, if equipped, are connected to
the provided key rings.
The ignition key and key rings, and RKE
transmitter, if equipped, are designed to
work together as a system to reduce the
risk of unintentionally moving the key out
of the RUN position. The ignition key has a
small hole to allow attachment of the
provided key ring.
It is important that any replacement ignition
keys have a small hole. See your dealer if a
replacement key is required.
The combination and size of the rings that
came with your keys were specifically
selected for your vehicle. The rings are
connected to the key like two links of a
chain to reduce the risk of unintentionallymoving the key out of the RUN position. Do
not add any additional items to the ring
attached to the ignition key.
Attach additional items only to the second
ring, and limit added items to a few
essential keys or small, light items no larger
than an RKE transmitter.
Interference from radio-frequency
identification (RFID) tags may prevent the
key from starting the vehicle. Keep RFID
tags away from the key when starting the
vehicle. The key that is part of the Remote
Keyless Entry (RKE) transmitter can be used
for the ignition and all locks.

learned, and turn the ignition on.
After two keys are learned, the remaining
keys can be learned by following the
procedure in “Programming with Two
Recognized Keys.”

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
