1 Washer fluid level checking
Check the washer fluid level through the level check
window .
When the level has dropped to the lower part of the
window or is no longer visible, refill the tank with
washer fluid.
2 Washer fluid filling
1. Open the passenger’s door.
2. Open the washer fluid reservoir cap and pour
in a mixture of windshield washer fluid and tap
water until the level reaches the top of the check
window.
3. Close the cap tightly after refilling.
CAUTION
• Do not substitute soapy water for washer
fluid. This could result in clogged washer
nozzles or spots on the painted surfaces of
the cab.
• Operating the washers continuously for
more than 20 seconds or when there is no
fluid in the reservoir could burn out the
washer motor.
NOTE:
When it is very cold, increase the ratio of washer
fluid to water. This will keep the mixture from freez-
ing.
