reduce fuel consumption. The system will stop
the engine automatically during a vehicle stop if
the required conditions are met. Releasing the
brake pedal or pressing the accelerator pedal

The Stop/Start feature is enabled after every

system will go into STOP/START READY and if all
other conditions are met, can go into a STOP/
START AUTOSTOP ACTIVE “Autostop” mode.
To Activate The Autostop Mode, The Following
Must Occur:
The system must be in STOP/START READY
state. A STOP/START READY message will be
displayed in the instrument cluster display
The vehicle must be completely stopped.
The gear selector must be in a forward gear
and the brake pedal pressed.
The engine will shut down, the tachometer will
move to the zero position and the Stop/Start
telltale will illuminate indicating you are in
Autostop. Customer settings will be maintained
upon return to an engine running condition.
