The Stop/Start function is developed to 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 will automatically re-start the engine.
The Stop/Start feature is enabled after every normal customer engine start. At that time, the system will gointo 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 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.
Prior to engine shut down, the system will check many safety and comfort conditions to see if they are fulfilled.
Detailed information about the operation of the Stop/ Start system may be viewed in the EVIC/DID Stop/Start Screen. In the following situations the engine will not stop:
Other Factors Which Can Inhibit Autostop Include:
It may be possible for the vehicle to be driven several times without the STOP/START system going into a STOP/START READY state under more extreme conditions of the items listed above.
While in a forward gear, the engine will start when the brake pedal is released or the throttle pedal is depressed.
The transmission will automatically re-engage upon engine restart.
Conditions That Will Cause The Engine To Start Automatically While In Autostop Mode:
