STOP/START SYSTEM IF
EQUIPPED
The Stop/Start function was developed to
reduce fuel consumption. The system will
stop the engine automatically during a ve-
hicle stop if the required conditions are met.
Releasing the brake pedal or pressing the
accelerator pedal will automatically restart
the engine.
This vehicle has been upgraded with a Heavy
Duty Battery, Starter, as well as other engine
parts, to handle the Additional engine starts.
Automatic Mode
The Stop/Start feature is enabled after every
normal customer engine start. At that time,
the system will go into STOP/START READY
and if all other conditions are met, can go
into a STOP/START AUTOSTOP ACTIVE “Au-
tostop” mode.
To Activate The Autostop Mode, The Following
Must Occur:
The system must be in STOP/START
READY state. A STOP/START READY mes-
sage will be displayed in the instrument
cluster display within the Stop/Start sec-
tion. Refer to “Warning Lights And Mes-
sages” in “Getting To Know Your Instru-
ment Panel” in your Owner’s Manual.
The vehicle must be completely stopped.
The gear selector must be in a forward gear
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 Autostop. Customer settings will be
maintained upon return to an engine running
condition.
Refer to the “Stop/Start System” in the
“Starting And Operating” in your Owner’s
Manual.
Possible Reasons The Engine Does Not
Autostop

check many safety and comfort conditions to
see if they are fulfilled. Detailed information

ations the engine will not stop:
