Maintenance and care
Washer fluid
Add washer fluid in the following
situations.
●Any washer does not work.
● The warning message
appears on the multi-informa-
tion display.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious pro\
blem.
CAUTION
■When refilling the washer fluid
Do not refill the washer fluid when the hybrid system is hot or operating, as
the washer fluid contains alcohol and may catch fire if spilled on the hybrid
system etc.
NOTICE
■Do not use any fluid other than washer fluid
Do not use soapy water or engine antifreeze instead of washer fluid.
Doing so may cause streaking on the vehicle’s painted surfaces.
■ Diluting washer fluid
Dilute washer fluid with water as necessary.
Refer to the freezing temperatures listed on the washer fluid tank.
