■ Stopping the engine in an emergency
If you want to stop the engine in an

emergency while driving the vehicle,
press and hold the engine switch for
more than 2 seconds, or press it briefly
3 times or more in succession.
(P.406)
However, do not touch the engine
switch while driving except in an emer-
gency. Turning the engine off while
driving will not cause loss of steering
or braking control, however, power
assist to the steering will be lost. This
will make it more difficult to steer
smoothly, so you should pull over and
stop the vehicle as soon as it is safe to
do so.
● If the engine switch is operated while
the vehicle is running, a warning mes-
sage will be shown on the multi-infor-
mation display and a buzzer sounds.
● When restarting the engine after an
emergency shutdown, press the
engine switch.
