1. This device may not cause harmful interference.
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.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than

PASS-Key III+ uses a radio frequency transponder in
the key that matches a decoder in the vehicle.
PASS-Key®III+ Electronic
Immobilizer Operation
Your vehicle has PASS-Key®III+ (Personalized
Automotive Security System) theft-deterrent system.
PASS-Key
®III+ is a passive theft-deterrent system.
The system is automatically armed when the key
is removed from the ignition.
The system is automatically disarmed when the key is
turned to ON/RUN, ACC/ACCESSORY or START
from the LOCK/OFF position.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
When the PASS-Key
®III+ system senses that someone
is using the wrong key, it prevents the vehicle from
starting. Anyone using a trial-and-error method to start
the vehicle will be discouraged because of the high
number of electrical key codes.
If the engine does not start and the security light on
the instrument panel cluster comes on when trying to
start the vehicle, there may be a problem with your
theft-deterrent system. Turn the ignition off and try again.

Monitor System (TPMS) is not working properly. The tire
pressure light also ashes and then remains on during
the same ignition cycle. SeeTire Pressure Light on
page 3-42. Several conditions may cause this message
to appear. SeeTire Pressure Monitor Operation on
page 5-67for more information. If the warning comes on

you want to rock your vehicle to attempt to free it, or if you
are driving in extreme off-road conditions and require
more wheel spin. SeeIf Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow on page 4-34. To turn the StabiliTrak
®
system on or off, seeStabiliTrak®System on page 4-6.
