To Activate The Autostop Mode, The Following Must
Occur:
1. The system must be in STOP/START READY state. ASTOP/START READY message will be displayed in
the Electronic Vehicle Information Center (EVIC)
within the Stop/Start section. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Understand-
ing Your Instrument Panel” for further information.
2. The vehicle must be completely stopped.
3. The transmission Gear Selector must be in Drive and the brake pedal depressed.
The engine will shut down, the tachometer will move to
the zero position and the stop/start telltale will illumi-
nate indicating you are in an Autostop. While in an Autostop, the Climate Controls system may automati-
cally adjust airflow to maintain cabin comfort. Customer
settings will be maintained upon return to an engine
running condition.
Possible Reasons The Engine Does Not AUTO
STOP
Prior to engine shut down, the system will check many
safety and comfort conditions to see if they are fulfilled.
In following situations the engine will not stop:
•
Driver ’s seat belt is not buckled
• Driver ’s door is not closed
• Outside temperature is less than 1°F (–17°C) or greater
than 104°F (40°C)
• The vehicle is on a steep grade
• Cabin heating or cooling is in process and an accept-
able cabin temperature has not been achieved

•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:

ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a
grounded, three-wire extension cord.1500 Models
The engine block heater cord is routed under the hood on
the passenger side of the vehicle near the right head lamp
assembly. It is located between the front grill and the
radiator, but underneath the black upper seal.
2500/3500 Models
The engine block heater cord is routed through the grille
by the right front tow hook.
It includes a removable cap that is secured by a tethered
strap. It also has a c-clip that is used for storage when not
in use for the winter months. During winter months,
remove the heater cord wiring assembly from itself on
the c-clip.

In 8-speed vehicles, the brake pedal must also be pressed
to shift from NEUTRAL into DRIVE or REVERSE when
the vehicle is stopped or moving at low speeds.
Eight–Speed Automatic Transmission — If
Equipped
Your vehicle is equipped with a state of the art, fuel
efficient eight-speed transmission. The electronic shifter
control is located on the instrument panel. The transmis-
sion gear (PRND) is displayed both above the shifter
control and in the Electronic Vehicle Information Center
(EVIC). To select a gear range, simply rotate the shifter
control. You must press the brake pedal to shift the
transmission out of PARK (see Brake/Transmission Shift
Interlock System). You must also press the brake pedal to
shift from NEUTRAL into DRIVE or REVERSE, when the
vehicle is stopped or moving at low speeds. To shift past
multiple gear ranges at once (such as Park to Drive),simply rotate the shifter control to the appropriate detent.
Select the DRIVE range for normal driving.
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake pedal when
shifting between these gears.
The transmission shifter control has only PARK, RE-
VERSE, NEUTRAL, and DRIVE positions. Manual down-
shifts can be made using the Electronic Range Select
(ERS) switches (described later in this section). Pressing
the GEAR-/GEAR+ switches (on the steering wheel)
while in the DRIVE position will select the highest

The system requires that the ignition be in ON/RUN
position or the engine running for all user requested
changes. When lowering the vehicle all of the doors,
must be closed. If a door is opened at any time while the
vehicle is lowering the change will not be completed
until the open door(s) is closed.
This system uses a lifting and lowering pattern which
keeps the headlights from incorrectly shining into on-
coming traffic. When raising the vehicle, the rear of the vehicle will move up first and then the front. When
lowering the vehicle, the front will move down first and
then the rear.
After the engine is turned off, it may be noticed that the
