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
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.
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.
Engine has not reached normal operating
temperature.
Battery charge is low.
The transmission is not in DRIVE (auto-
matic transmission) or NEUTRAL (manual
transmission).
Hood is open.
Vehicle is in 4WD LOW transfer case
mode.
Exhaust system regeneration in process.
Other Factors Which Can Inhibit Autostop
Include:
Fuel level.
Accelerator pedal input (automatic trans-
mission only).
Engine temperature too high.
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
Automatic Transmission:

While in DRIVE, 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. During this tran -
sition, the brakes will hold the vehicle to avoid
undesired vehicle movement.
Manual Transmission:

When the gear selector is in NEUTRAL, the
engine will start when the clutch pedal is
pressed. The vehicle will go into STOP/START
SYSTEM NOT READY mode until the vehicle
speed is greater than 4 mph (7 km/h).

Conditions That Will Cause The Engine To Start
Automatically While In Autostop Mode:

The transmission gear selector is moved
from DRIVE to REVERSE or NEUTRAL.
To maintain cabin temperature comfort.
HVAC is set to full defrost mode.
Battery voltage drops too low.
Low brake vacuum (e.g. after several brake
pedal applications).
Stop/Start OFF switch is pushed.
4WD system is put into 4WD LOW mode.
The emissions system requires it.
A Stop/Start system error occurs.
HVAC system temperature or fan speed is
manually adjusted.
