The main display area will normally display the main
menu or the screens of a selected feature of the main
menu. The main display area also displays “pop up”
messages that consist of approximately 60 possible warn-
ing or information messages. These pop up messages fall
into several categories:
•Five Second Stored Messages
When the appropriate conditions occur, this type of
message takes control of the main display area for five
seconds and then returns to the previous screen. Most of
the messages of this type are then stored (as long as the
condition that activated it remains active) and can be
reviewed from the “Messages” main menu item. As long
as there is a stored message, an “i” will be displayed in
the DID’s compass/outside temp line. Examples of this
message type are “Right Front Turn Signal Lamp Out”
and “Low Tire Pressure”.

To Start The Engine While In Autostop Mode
While in DRIVE the engine will start when the brake
pedal is released or the throttle pedal is depressed. The
transmission will automatically reengage upon engine
restart. During this transition the brakes will hold the
vehicle to avoid undesired vehicle movement.
Conditions that will cause the engine to start automati-
cally while in Autostop mode.
The Engine Will Start Automatically When:
•The transmission selector is moved from DRIVE to
REVERSE or NEUTRAL
•To maintain cabin temperature near the HVAC settings
•HVAC is set to full defrost mode
•Autostop time exceeds 5 minutes
•Battery voltage drops too low
•Low brake vacuum (e.g. after several brake pedal
applications)
•STOP/START OFF switch is pressed
•4WD system is put into 4LO mode
•The emissions system requires it
•A STOP/START system error occurs
Conditions that force an automatic shift to PARK while
in Autostop mode.
The Engine Will Not Start Automatically and the Trans-
mission will be placed in PARK if:
•The driver door is open and brake pedal released
•The driver door is open and the driver seat belt is
unbuckled
•The engine hood has been opened
•A STOP/START system error occurs

Electronically Shifted Transfer Case
(Four-Position Switch) — If Equipped
This is an electronic shift transfer case and is operated by
the 4WD Control Switch (Transfer Case Switch), which is
located on the instrument panel.
This electronically shifted transfer case provides four
mode positions:
•Two-wheel drive high range (2WD)
•Four-wheel drive lock range (4WD LOCK)
•Four-wheel drive low range (4WD LOW)
•Neutral (NEUTRAL)
This electronically shifted transfer case is designed to be
driven in the two-wheel drive position (2WD) for normal
street and highway conditions on dry, hard surfaced
roads.
When additional traction is required, the transfer case
4WD LOCK and 4WD LOW positions can be used to
maximize torque to the front driveshaft, forcing the front
and rear wheels to rotate at the same speed. This is
accomplished by rotating the 4WD Control Switch to the
desired position. Refer to “Shifting Procedure” in this
section for specific shifting instructions. The 4WD LOCK
Transfer Case Switch (Four-Position)
498 STARTING AND OPERATING

and 4WD LOW positions are designed for loose, slippery
road surfaces only. Driving in the 4WD LOCK and 4WD
LOW positions on dry hard surfaced roads may cause
increased tire wear and damage to the driveline compo-
nents.
NOTE:The transfer case NEUTRAL position is selected
by pressing the button located on the lower left hand
corner of the 4WD Control Switch. The transfer case
NEUTRAL position is to be used for recreational towing
only. Refer to “Recreational Towing” in “Starting and
Operating” for further information.
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD and
4LOW) are located in the instrument cluster and indicate
the current and desired transfer case selection. When you
select a different transfer case position, the indicator
lights will do the following:
If All Shift Conditions Are Met:
1. The current position indicator light will turn OFF.
2. The selected position indicator light will flash until the
transfer case completes the shift.
3. When the shift is complete, the indicator light for the
selected position will stop flashing and remain ON.
If One Or More Shift Conditions Are Not Met:
1. The indicator light for the current position will remain
ON.
2. The newly selected position indicator light will con-
tinue to flash.
3. The transfer casewill notshift.
