POSSIBLE REASONS THE ENGINE
DOES NOT AUTOSTOP
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 instrument cluster
display Stop/Start Screen. In the following situations,
the engine will not stop:
•
Driver’s seat belt is not buckled.
•
Driver’s door is not closed.
•
Battery temperature is too warm or cold.
•
Battery charge is low.
•
The vehicle is on a steep grade.
•
Cabin heating or cooling is in process and an
acceptable cabin temperature has not been
achieved.
•
HVAC is set to full defrost mode at a high blower
speed.
•
HVAC is set to MAX A/C.
•
Engine has not reached normal operating
temperature.
•
The transmission is not in a forward gear.
•

•
5 mph (8 km/h) threshold has not been achieved

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 previously listed.
