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.

To control the fast idle:
To Enable the Fast idle, press and release the
Cruise Control On/Off button and ensure that
the LED is lit.
For the preset Fast Idle, press and release the
cruise set switch. This will set the preset fast
idle speed.
For the variable fast idle, press and hold the
accelerator at the desired RPM, then press
and release the cruise control cruise set switch

One of the following actions will turn off the fast idle:
Pressing the brake.
Selecting the Cancel button.
Releasing the Parking Brake.
The transmission shifter is moved out of PARK (P)
or NEUTRAL (N).
Selecting the cruise control on/off button when it
was previously on.
Adjustable Throttle and Brake Pedal
On vehicles with this feature, you can change the
position of the throttle and brake pedals.
This feature is designed for shorter drivers, since the
pedals cannot move farther away from the standard
position, but can move toward the driver for better
pedal reach.
No adjustment to the pedals can be made when the
vehicle is in REVERSE (R) or while using the cruise
control.
The switch used to adjust
the pedals is located on the
instrument panel below the
climate control system.
Press the arrow at the bottom of the switch to move the
pedals closer to your body. Press the arrow at the top of
the switch to move the pedals away from your body.

How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact your
dealer/retailer in the area where you will be parking your
vehicle. The dealer/retailer can give you the best advice
for that particular area.
Active Fuel Management™
Your vehicle’s V8 engine may have Active Fuel
Management™. This system allows the engine to
operate on either all or half of its cylinders, depending
on the driving conditions.
When less power is required, such as cruising at a
constant vehicle speed, the system will operate in the
half cylinder mode, allowing your vehicle to achieve
better fuel economy. When greater power demands are
required, such as accelerating from a stop, passing,
or merging onto a freeway, the system will maintain
full-cylinder operation.
If your vehicle has an Active Fuel Management™
indicator, seeDIC Operation and Displays (With DIC
Buttons) on page 3-57orDIC Operation and Displays
(Without DIC Buttons) on page 3-63for more information
on using this display.
Automatic Transmission Operation
If your vehicle is has an automatic transmission,
it has an electronic shift position indicator within the
instrument panel cluster. This display comes on when
the ignition key is turned to the ON/RUN position.
There are several different
positions for the shift lever.
