WARNING
• Do not open the sub-tank cap unless necessary.
When checking the coolant level, check the reservoir tank when the engine is cold.
• Immediately after the engine is stopped, the coolant is hot and pressure is accumulated in the radia-
tor.
If the cap is removed in this condition, it is dangerous that you may get burn injury.
Always wait for the temperature to go down, turn the cap slowly to release the pressure, then re-
move the cap with care.
