■ Stopping the engine in an emergency
If you want to stop the engine in an emer-
gency 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.328)
However, do not touch the engine switch
while driving except in an emergency.
Turning the engine off while driving will
not cause loss of steering or braking con-
trol, but the power assist to these systems
will be lost. This will make it more difficult
to steer and brake, so you should pull
over and stop the vehicle as soon as it is
safe to do so.
■ When parking
Exhaust gases include harmful carbon
monoxide (CO), which is colorless and
odorless. Observe the following precau-
tions.
Failure to do so may cause exhaust gases
to enter the vehicle and may lead to an
accident caused by light-headedness, or
may lead to death or a serious health
hazard.
● If the vehicle is in a poorly ventilated
area or a closed area, such as a
garage, stop the engine.
● Do not leave the vehicle with the
engine running for a long time. If such
a situation cannot be avoided, park the
vehicle in an open space and ensure
that exhaust fumes do not enter the
vehicle interior.
● Do not leave the engine running in an
area with snow build-up, or where it is
snowing. If snowbanks build up around
the vehicle while the engine is running,
exhaust gases may collect and enter
the vehicle.
