WARNING
The engine cooling system is pressurized, par-
ticularly when the engine is warm. When
opening the cap, you could be scalded by hot
coolant spraying out. There is a risk of injury.
Let the engine cool down before opening the
cap. Wear eye and hand protection when
opening the cap. Open the cap slowly half a
turn to allow pressure to escape.
Only check the coolant level and/or fill the
coolant if the vehicle is on a level surface and
the engine has cooled down. The coolant tem-
perature must be below 122 ‡ (50 †).
! Check the engine cooling and heating sys-
tem regularly for leaks.
If a large quantity of coolant is lost, have the
cause traced and rectified at a qualified
specialist workshop.

contact with skin, eyes or clothing. In case of
contact with eyes, rinse immediately with
plenty of clean water. Clean affected areas of
