NOTICE
■ When cleaning the air intake
vents
When cleaning the air intake
vents, make sure to only use a
vacuum to suck out dust and
clogs. If a compressed air blow
gun, etc. is used to blow out dust
and clogs, the dust or clogs may
be pushed into the air intake
vents, which may affect the per-
formance of the hybrid battery
(traction battery) and cause a
malfunction.
■ To prevent damage to the
vehicle
● Do not allow water or foreign
matter to enter the air intake
vents when the covers are
removed.
● Carefully handle the removed
filter so that it will not be dam-
aged. If the filter is damaged,
have it replaced with a new filter
by your Toyota dealer.
● Make sure to reinstall the filters
and covers to their original posi-
tions after cleaning.
Do not install anything to the air
●
intake vents other than the
exclusive filters for this vehicle
or use the vehicle without the fil-
ters installed.
