■Automatic enabling of the Stop
& Start system
If the Stop & Start system is dis-
abled using the Stop & Start cancel
switch, it will be automatically
re-enabled once the engine switch
is turned off and then the engine is
started.
When the engine is stopped by
the Stop & Start system when
the vehicle is on an incline,
when the brake pedal is
released, brake force is tempo-
rarily maintained to prevent the
vehicle from rolling backwards
before the engine is restarted and drive force is generated.
When drive force is generated,
the maintained brake force is
automatically canceled.
This function operates on flat
surfaces as well as steep
inclines.
Sound may be generated
from the brake system, but
this does not indicate a mal-
function.
Brake pedal response may
change and vibration may
occur, but this does not indi-
cate a malfunction.
■Points for use
●If the engine switch is pressed
when the engine is stopped by the
Stop & Start system, the engine
will not be able to be restarted by
the automatic engine start func-
tion. In this case, restart the
engine using the normal engine
starting procedure. ( P.162, 163)
●When the engine is being
restarted by the Stop & Start sys-
tem, the power outlets may be
temporarily unusable, but this
does not indicate a malfunction.
