268 STARTING AND OPERATING
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 set to MAX A/C.
• Engine has not reached normal operating temperature.
• The transmission is not in a forward gear.
• Hood is open.
• Vehicle is in 4WD LOW transfer case mode.
• Brake pedal is not pressed with sufficient pressure.
Other Factors Which Can Inhibit Autostop Include:
• Accelerator pedal input.
• Engine temp too high.
• 5 mph (8 km/h) threshold not achieved from previous
AUTOSTOP.
• Steering angle beyond threshold.
• Adaptive Cruise Control is on and speed is set.
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.
To Start The Engine While In Autostop Mode
While in a forward gear, the engine will start when the brake
pedal is released or the throttle pedal is depressed. The trans-
mission will automatically re-engage upon engine restart.
