Section 2 Features and Controls
2-1

One key is used for the
ignition, the door and all
other locks.When a new vehicle is delivered, the dealer removes
the key tag and gives it to the first owner. The tag has a
code on it that tells your dealer how to make extra keys.
For vehicle security, keep the key tag in a safe place and
also record the key number somewhere other than inside
of the vehicle. If you lose your key, you will be able to
have a new one made easily using the tag.
Your vehicle may have an electronic immobilizer
designed to protect your car against theft. If so, only
keys with the correct electronic code can be used
to start the vehicle. Even if a key has the same profile,
it will not start the engine if the electronic code is
incorrect. If you need a new key, contact your dealer
who can obtain the correct key code. SeeRoadside
Assistance Program on page 7-6for more information.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.

Immobilizer
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. this device may not cause interference, and
2. this device must accept any interference received,
including interference that may cause undesired
operation.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. this device may not cause interference, and
2. this device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
Immobilizer Operation
Your vehicle may have a passive theft-deterrent system.
The immobilizer system prevents your vehicle from
being started by unauthorized persons.
If your vehicle has an immobilizer system, your vehicle
has a special key that works with the theft-deterrent
system. There is a transponder in the key head that is
electronically coded. The correct key will start the
vehicle. An invalid key immobilizes the engine.
The immobilizer system isolates the power supply to
the ignition system, the fuel pump and the fuel injectors.
The engine immobilizer is activated after the key is
turned to LOCK and removed from the ignition.
The security light located on the top center of the
instrument panel in the secondary information center
will flash when the immobilizer is active. If the light does
not flash after removing the key, have the system
checked by your dealer.
The immobilizer system works when you turn the key to
START. If the immobilizer system does not recognize the
electronic code, the engine will not start and the security
indicator will continue blinking. If your key is ever
damaged, you may not be able to start your vehicle.
