WARNING
Stopping the hybrid system in an
■
emergency
●
If you want to stop the hybrid system in
an emergency while driving the vehi-
cle, press and hold the power switch
for more than 2 seconds, or press it
briefly 3 times or more in succession.
(→P.420)
However, do not touch the power
switch while driving except in an emer-
gency. Turning the hybrid system 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 power 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 hybrid system
after an emergency shutdown, press
the power switch.
Changing power switch modes
Modes can be changed by pressing
the power switch with the brake pedal
released. (The mode changes each
time the switch is pressed.)
