6-3. Do-it-yourself maintenance

If any washer does not work or the 
warning message appears on the 
multi-information display, the washer 
tank may be empty. Add washer fluid.

Check if the treadwear indicators are 
showing on the tires. Also check the 
tires for uneven wear, such as excessive 
wear on one side of the tread.
Check the spare tire condition and 
pressure if not rotated.

New tread

Treadwear indicator

The location of treadwear indicators is 
shown by a “TWI” or “

” mark, etc., 

molded into the sidewall of each tire.
Replace the tires if the treadwear indica-
tors are showing on a tire.

Adding the washer fluid

WARNING

■

When adding washer fluid

Do not add washer fluid when the engine 

is hot or running as washer fluid contains 

alcohol and may catch fire if spilled on 

the engine, etc.

NOTICE

■

Do not use any fluid other than 

washer fluid

Do not use soapy water or engine anti-

freeze instead of washer fluid.

Doing so may cause streaking on the 

vehicle’s painted surfaces, as well as 

damaging the pump leading to problems 

of the washer fluid not spraying.

■

Diluting washer fluid

Dilute washer fluid with water as neces-

sary.

Refer to the freezing temperatures listed 

on the label of the washer fluid bottle.

Tires

Replace or rotate tires in accor-
dance with maintenance schedules 
and treadwear.
