STOP/START SYSTEM —
DIESEL MODELS WITH
MANUAL TRANSMISSION
ONLY
The Stop/Start function is developed to save
fuel and reduce emissions. The system will
stop the engine automatically during a ve-
hicle stop if the required conditions are met.
Pressing the clutch pedal will automatically
restart the vehicle.
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
3 mph (5 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 ACTIVE mode.
To Activate The STOP/START AUTO STOP ACTIVE
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. Refer to “Instrument Cluster Dis-
play” in “Getting To Know Your Instrument
Panel” for further information.
• Vehicle speed must be less 3 mph (5 km/
h).

flow will be reduced.
