3. WASHER TANK

C: CAUTION

• Connect the connectors and hoses securely during reassembly.
• After reassembly, make sure functional parts operate smoothly.
• Be careful with the airbag system wiring harness which passes near electrical parts and switches.
• All airbag system wiring harness and connectors are colored yellow. Do not use a tester equipment on
these circuits.
• Care must be taken when connecting the hoses to pipes so that there are no bends or blockage.
• If even a small amount of silicon oil or grease enters tank and washer fluid passages, an oil film will be
formed on the glass and will cause the wiper to chatter and judder. Make sure that no oil comes into contact
with the system.
