Emergency Power System Off
The POWER button may be used to turn the po wer system off due to an emergency
situation even while driving. If you must turn the powe r system off, do either of the
following operations:
• Press and hold the POWER button for about two seconds.
• Firmly press the POWER button three times.
The steering wheel will not lock. However, because turning off the power system
disables the power assist the power syst em provides to the steering and braking
systems, it will require significantly more physical effort and time to steer and slow
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 automatically changes to
(P after the vehicle comes to a complete
stop. Then, the power mode changes to VEHICLE OFF.
