Your vehicle may have a remote starting feature. This
feature allows you to start the engine from outside the
vehicle. It may also start the vehicle’s heating or air
conditioning systems, rear window defogger, and heated
seats. SeeHeated Seats on page 1-6andHeated and
Cooled Seats on page 1-7for additional information.

control system will heat or cool the inside of the vehicle at
the setting the vehicle was set to when the vehicle was
last turned off. The rear window defogger will be turned
on by the climate control system when it is cold outside.
If the vehicle has heated seats, they may also turn on
when it is cold outside. Cooled seats are not activated
during a remote start. Normal operation of the system will
return after the key is turned to the ON/RUN position.
Laws in some communities may restrict the use of remote
starters. For example, some laws may require a person
using the remote 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 your vehicle is low
on fuel. Your vehicle may run out of fuel.
If your vehicle has the remote start feature, the RKE
transmitter functions will have an increased range
of operation. However, the range may be less while
the vehicle is running.There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry (RKE) System on page 2-4for additional

PASS-Key®III+ Electronic
Immobilizer
The PASS-Key III+ system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
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
an authorized service facility could void authorization to
use this equipment.
PASS-Key III+ uses a radio frequency transponder in
the key that matches a decoder in the vehicle.
2-18

PASS-Key®III+ Electronic
Immobilizer Operation
Your vehicle is equipped with 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.
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.
When trying to start the vehicle if the engine does not
start and the security light on the instrument panel
cluster comes on, there may be a problem with your
theft-deterrent system. Turn the ignition off and try again.If the engine still does not start, and the key appears to
be not damaged, try another ignition key. At this time, you
may also want to check the fuse, seeFuses and Circuit
Breakers on page 5-101. If the engine still does not start
with the other key, your vehicle needs service. If your
vehicle does start, the rst key may be faulty. See your
dealer/retailer who can service the PASS-Key
®III+ to
have a new key made. In an emergency, contact
Roadside Assistance. SeeRoadside Assistance
Program on page 7-7.
It is possible for the PASS-Key
®III+ decoder to “learn”
the transponder value of a new or replacement key.
Up to 10 keys may be programmed for the vehicle.
The following procedure is for programming additional
keys only. If all the currently programmed keys are lost
or do not operate, you must see your dealer/retailer or a
locksmith who can service PASS-Key
®III+ to have keys
made and programmed to the system.
See your dealer/retailer or a locksmith who can service
PASS-Key
®III+ to get a new key blank that is cut
exactly as the ignition key that operates the system.

Ignition Positions
The ignition has four
different positions:
In order to shift out of P (Park), ignition must be in the
ON/RUN and the regular brake pedal must be applied.
Notice:Using a tool to force the key to turn in the
ignition could cause damage to the switch or break
the key. Use the correct key, make sure it is all the
way in, and turn it only with your hand. If the key
cannot be turned by hand, see your dealer/retailer.
A (LOCK/OFF):This position locks the ignition. It also
locks the transmission and steering column. This is the
only position in which the ignition key can be inserted or
removed.The steering can bind with the wheels turned off center.
If this happens, move the steering wheel from right to left
while turning the key to ACC/ACCESSORY. If this
doesn’t work, then the vehicle needs service.
B (ACC/ACCESSORY):This position lets the radio
and windshield wipers operate while the engine is off.
To use ACC/ACCESSORY, turn the key clockwise.
C (ON/RUN):This position can be used to operate
electrical accessories and to display some of the
warning and indicator lights. The switch stays in this
position when the engine is running.
If you leave the key in the ACC/ACCESSORY or
ON/RUN position with the engine off, the battery could
be drained. You may not be able to start the vehicle
if the battery is allowed to drain for an extended period
of time.
D (START):This position starts the engine. When the
engine starts, release the key. The ignition switch
returns to ON/RUN for driving.
A warning tone will sound and the Driver Information
Center (DIC) will display DRIVER DOOR OPEN
when the driver door is opened if the ignition is in
LOCK/OFF, ACC/ACCESSORY and the key is in the
ignition. SeeDIC Warnings and Messages on page 3-56
for more information.
