Other factors which can inhibit AutoStop include: fuel level, accelerator pedal input,
engine temp too high and steering angle.
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 DRIVE the engine will start when the brake pedal is released or the throttle
pedal is depressed. The transmission will automatically reengage upon engine restart.
During this transition the brakes will hold the vehicle to avoid undesired vehicle
movement.
Conditions that will cause the engine to start automatically while in Autostop mode.
The Engine Will Start Automatically When:
• The transmission selector is moved from DRIVE to REVERSE or NEUTRAL
• To maintain cabin temperature near the HVAC settings
• HVAC is set to full defrost mode
• Autostop time exceeds 5 minutes
• Battery voltage drops too low
• Low brake vacuum (e.g. after several brake pedal applications)
• STOP/START OFF switch is pressed
• 4WD system is put into 4LO mode
• The emissions system requires it
• A STOP/START system error occurs
Conditions that force an automatic shift to PARK while in Autostop mode.
The Engine Will Not Start Automatically and the Transmission will be placed in PARK
if:
• The driver door is open and brake pedal released
• The driver door is open and the driver seat belt is unbuckled
• The engine hood has been opened
• A STOP/START system error occurs
The engine may then be restarted by moving the transmission shift selector out of
PARK (e.g. to DRIVE) or, in some cases, only by a KEY START. The Electronic Vehicle
Information Center (EVIC)/Driver Information Display (DID) will display a SHIFT OUT
OF PARK message, or a STOP/START KEY START REQUIRED message, to indicate
which action is required. Refer to “Electronic Vehicle Information Center (EVIC) or
Driver Information Display (DID)” in “Understanding Your Instrument Panel” for
further information.
