Radiators and condenserCheck the radiators and condenser and remove any foreign objects.
If any of the above parts are extr emely dirty or you are not sure of
their condition, have your vehicl e checked by your Toyota dealer.
Brake fluid
■ Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN”
lines on the tank.
If the level is low, take your vehi-
cle to a Toyota dealer as soon as
possible. Do not drive your vehi-
cle if the red brake system warn-
ing light is on. Call a Toyota
dealer for assistance.
CAUTION
■The radiators and condenser may be hot after driving
Do not touch the radiators or condenser, as they may be hot and may be
burned.
CAUTION
■ When filling the reservoir
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets in your eyes, flush your eyes with clean water immediately.

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.
