a slight application of the accelerator will
supply maximum traction. When starting
with only one rear wheel on an excessively
slippery surface, slight momentary applica-
tion of the parking brake may be necessary to
gain maximum traction.
WARNING!
When servicing vehicles equipped with a
limited-slip or locking differential never
run the engine with one rear wheel off the
ground since the vehicle may drive through
the rear wheel remaining on the ground
and result in unintended movement.
Care should be taken to avoid sudden accel-
erations when both rear wheels are on a slip-
pery surface. This could cause both rear
wheels to spin, and allow the vehicle to slide
sideways on the crowned surface of a road or
in a turn.
STOP/START SYSTEM — IF
EQUIPPED
The Stop/Start function is developed to save
fuel and reduce emissions. The system will
stop the engine automatically during a
vehicle stop if the required conditions are
met. Releasing the brake pedal will automat-
ically restart the engine.
Vehicles equipped with eTorque contain a
heavy duty motor generator and an additional
hybrid electric battery to store energy from
vehicle deceleration for use on engine
startup after a stop as well as providing
launch torque assist.

Automatic Mode

The Stop/Start feature is enabled after every
normal customer engine start. It will remain
in STOP/START NOT READY until you drive
forward with a vehicle speed greater than
2 mph (3 km/h). At that time, the system
will go into STOP/START READY and if all
other conditions are met, can go into an
STOP/START AUTO STOP
"Autostop" mode.
To Activate The Autostop Mode, The Following
Must Occur:
1. The system must be in STOP/START
READY state. A STOP/START READY
message will be displayed in the instru-
ment cluster within the Stop/Start
section. Refer to "Instrument Cluster
Display" in "Getting To know Your Instru-
ment 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 illuminate indicating you
are in an Autostop. While in an Autostop, the
Climate Controls system may automatically
adjust airflow to maintain cabin comfort.
Customer settings will be maintained upon
return to an engine running condition.
