Immobilizer Operation
(Keyless Access)
Your vehicle has a passive theft-deterrent system.
The system is automatically armed when the ignition
control knob is turned to LOCK/OFF.
The immobilization system is disarmed when the ignition
control knob is pushed in and a valid transmitter is
found in the vehicle.
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.
The system has one or more keyless access transmitters
that are matched to an immobilizer control unit in your
vehicle. Only a correctly matched keyless access
transmitter will start the vehicle. If the keyless access
transmitter is ever damaged, you may not be able to
start your vehicle.
When trying to start the vehicle, if the engine does not
start and the security light comes on, there may be a
problem with your immobilizer system. Turn the ignition
control knob off and try again.If the ignition control knob does not rotate, and the
keyless access transmitter appears to be undamaged,
try another keyless access transmitter. Or, you may
try placing the transmitter in the transmitter pocket
located in the center console. See “Electronic Key Not
Detected” underDIC Warnings and Messages on
page 3-58. At this time, you may also want to check the
fuse. SeeFuses and Circuit Breakers on page 5-115.
If the ignition control knob still does not rotate with
the other transmitter, your vehicle needs service. If the
ignition control knob does rotate, the rst transmitter
may be faulty. See your dealer/retailer who can service
the theft-deterrent system and have a new keyless
access transmitter programmed to the vehicle.
It is possible for the immobilizer system to learn new or
replacement keyless access transmitters. Up to 4 keyless
access transmitters can be programmed for the vehicle.
To program additional transmitters, see “Matching
transmitter(s) to Your Vehicle” underKeyless Access
System Operation on page 2-8.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

Ignition Positions (Keyless Access)
You can turn the ignition control knob to four different
positions.
To shift out of P (Park), ignition must be in the ON/RUN
or ACC/ACCESSORY and the regular brake pedal
must be applied.
Using a tool to force the ignition control knob from its
cylinder could damage it.
Make sure the keyless access transmitter is inside the
vehicle when trying to turn the ignition control knob.A (LOCK/OFF):The ignition control knob cannot be
removed from the vehicle. The keyless access
transmitter must be inside the vehicle to start the
engine. This position locks the ignition and shifter on
automatic transmission vehicles, and the ignition
and steering wheel on manual transmission vehicles.
B (ACC/ACCESSORY):This position allows you to use
things like the radio and the windshield wipers when
the engine is off. This position will allow you to turn off
the engine.
C (ON/RUN):This position is for driving. It is the position
the ignition switch returns to after the engine starts, and
the control knob is released.
If you need to shift the transmission out of P (Park), the
ignition control knob has to be in ACC/ACCESSORY or
ON/RUN.
The battery could be drained if you leave the key in the
ACC/ACCESSORY or ON/RUN position with the engine
off. You may not be able to start your vehicle if the battery
is allowed to drain for an extended period of time.
D (START):This position starts the engine.

Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the engine is turned off:
Audio System
Power Windows
Sunroof (if equipped)
Power to the audio system will work up to 10 minutes or
until the driver door is opened. Power to the windows or
sunroof will work up to 10 minutes or until any door is
opened. For an additional 10 minutes of operation, close
all the doors and turn the key to ON/RUN and then back
to LOCK/OFF.
Starting the Engine
Place the transmission in the proper gear.
Automatic Transmission
Move the shift lever to P (Park) or N (Neutral). The
engine will not start in any other position. To restart
the engine when the vehicle is already moving, use
N (Neutral) only.If the vehicle has the keyless access system, put your
foot on the brake pedal and turn the ignition control knob
to the START position. When the engine begins cranking,
let go of the ignition control knob, it will return to the
ON/RUN position.
If the transmitter is not in the vehicle or something is
interfering with the transmitter, the Driver Information
Center (DIC) will display Electronic Key Not Detected.
SeeDIC Warnings and Messages on page 3-58for
more information.
If the battery in the keyless access transmitter needs
replacing, the DIC displays Replace Battery In Remote
Key. The vehicle can still be driven. See “Battery
Replacement” underKeyless Access System Operation
on page 2-8for more information.
Notice:Do not try to shift to P (Park) if the
vehicle is moving. If you do, you could damage
the transmission. Shift to P (Park) only when
the vehicle is stopped.Manual Transmission
The shift lever should be in neutral position and the
parking brake engaged. Hold the clutch pedal down to
the oor and start the engine. The vehicle will not start if
the clutch pedal is not all the way down.
2-33

Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition key to START. If the vehicle has the keyless
access system, make sure there is a keyless access
transmitter in the vehicle. When the engine starts,
let go of the ignition. The idle speed will go down
as your engine gets warm. Do not race the engine
immediately after starting it. Operate the engine and
transmission gently to allow the oil to warm up and
lubricate all moving parts.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is turned
to the START position, and then released when the
engine begins cranking, the engine will continue
cranking for a few seconds or until the vehicle starts.
If the engine does not start and the key is held in
START for many seconds, cranking will be stopped
after 15 seconds to prevent cranking motor damage.
To prevent gear damage, this system also prevents
cranking if the engine is already running. Engine
cranking can be stopped by turning the ignition
switch to ACC/ACCESSORY or LOCK/OFF.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheatand damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.
2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F or−18°C),
it could be ooded with too much gasoline. Try
pushing the accelerator pedal all the way to the oor
and holding it there as you hold the key in START
for up to a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the cranking
motor to cool down. When the engine starts, let go of
the key and accelerator. If the vehicle starts briey
but then stops again, do the same thing. This clears
the extra gasoline from the engine. Do not race the
engine immediately after starting it. Operate the
engine and transmission gently until the oil warms
up and lubricates all moving parts.
Notice:The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the engine
operates. Before adding electrical equipment, check
with your dealer/retailer. If you do not, the engine
might not perform properly. Any resulting damage
would not be covered by the vehicle warranty.

Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot exhaust
parts under the vehicle and ignite. Do not park
over papers, leaves, dry grass, or other things that
can burn.
2-49

If none of the above have made the light turn off, your
dealer/retailer can check the vehicle. The dealer/retailer
has the proper test equipment and diagnostic tools to
x any mechanical or electrical problems that might have
developed.
Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
The vehicle will not pass this inspection if the check
engine light is on with the engine running, or if the
key is in the ON/RUN and the light is not on.
For vehicles with a Keyless Access ignition,
make sure the transmitter is in the passenger
compartment. SeeIgnition Positions (Key Access)
on page 2-31orIgnition Positions (Keyless Access)
on page 2-32.
The vehicle will not pass this inspection if the OBD II
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen
if the battery has recently been replaced or if the
battery has run down. The diagnostic system is
designed to evaluate critical emission control
systems during normal driving. This can take several
days of routine driving. If this has been done and the
vehicle still does not pass the inspection for lack of
OBD II system readiness, your dealer/retailer can
prepare the vehicle for inspection.
