Emergency Engine Stop
The ENGINE START/STOP button may be used to stop the engine due to an
emergency situation even while driving. If you must stop the engine, do either of the
following operations:
• Press and hold the ENGINE START/STOP button for about two seconds.
• Firmly press the ENGINE START/STOP button three times.
The steering wheel will not lock. However, because turning off the engine disables
the power assist the engine provides to the steering and braking systems, it will
require significantly more physical effort an d time to steer and slow the vehicle. Use
both feet on the brake pedal to slow down the vehicle and stop immediately in a
safe place.
The transmission automa tically changes to
(P after the vehicle comes to a complete
stop.
Then, the power mode changes to VEHICLE OFF.
Then press the ENGINE START/STOP button twice without depressing the brake
pedal to change the mode to VEHICLE OFF.
1 Emergency Engine Stop
Do not press the ENGINE START/STOP button while
driving unless it is absolute ly necessary for the engine
to be turned off.
If you press the ENGINE START/STOP button while
driving, the beeper sounds.
