(1) Remove the maintenance lid located in the luggage
compartment.
(2) If the vehicle has been run, leave it for 5 min. or more
in an ordinary temperature (10
_
C to 30
_
C) to allow the
accumulator internal pressure to drop.
NOTE
If the ambient temperature is less than 10
_
C or less,
allow more time to leave the vehicle to stand idle.
