tion, the recorded position may be
slightly different w hen it is recalled.
■When recalling the driving posi-
tion
Take care when recalling the driving
position so that the head restraint
does not touch the ceiling.
■If the 12-volt battery is discon-
nected
The memorized positions are
erased.
■Registering procedure
Record your driving position to
button “1” or “2” before perform-
ing the following:
Carry only the key you want to
register, and then close the
driver’s door.
If 2 or more keys are in the vehi-
cle, the driving position cannot
be recorded properly.

caused by light-headedness, or
may lead to death or a serious
health hazard.
●If the vehicle is in a poorly venti-
lated area or a closed area,
such as a garage, stop the
hybrid system.
●Do not leave the vehicle with
the hybrid system operating 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 ve hicle interior.
●Do not leave the hybrid system
operating in an area with snow
build-up, or where it is snowing.
If snowbanks build up around
