Maintenance and care
■Using the gauge (if equipped)
The washer fluid level can be checked by
observing  the  position  of  the  level  on  the
liquid-covered holes in the gauge.
If  the  level  falls  below  the  second  hole
from the bottom (the “LOW” position), refill
the washer fluid.

Pull  the  wiper  insert  out  past
the  stopper  on  the  wiper  blade,
and then continue to pull until it
is completely removed.
Lightly  grasp between  the  claws  of
the  wiper  blade  to  allow  the  wiper
insert  to  lift  up,  making  it  easier  to
remove.
Remove the 2 metal plates from
the  old  wiper  insert  and  install
them  to  the  replacement  wiper
insert.
Insert  the  wiper  insert  starting  from  the  claw  at  the  center  of the
wiper  blade.  Pass  the  wiper  insert  through  the  3  claws  so  that  it
sticks out from the stopper, and then pass the wiper insert thr ough
the final remaining claw.
Applying  a  small  amount  of  washer  fluid  to  the  wiper  insert  can   make  it
easier to insert the claws into the grooves.
