situation even while driving. If you must tu rn the power system off, do either of the
following operations:

the vehicle. Use both feet on the brake pe dal to slow down the vehicle and stop
immediately in a safe place.
The gear position auto matically changes to
(P after the vehicle comes to a complete
stop. Then, the power mode changes to VEHICLE OFF.
