WARNING
ARNING Risk of /re‑ and injury from
antifreeze
If antifreeze comes into contact with hot com-
ponent parts in the engine compartment, it
may ignite. #
Allow the engine tocool down before you
to p up the antifreeze. #
Make sure that no antif reeze spills out
next tothe /ller opening. #
Thoroughly clean the antifreeze from
component parts before starting the
ve hicle. &
W WARNING
ARNING Risk of scalding from hot cool-
ant
If yo u open the cap, you could be scalded. #
Letthe mo tor cool down before opening
th e cap. #
When opening the cap, wear pr otective
glo ves and saf ety glasses. #
Open the cap slo wlytorelease pressure. Check and
top up the coolant only when theve hi-
cle is stationary and in a horizontal position and
th e engine has cooled down. The coolant temp era-
ture must be below 50°C. &
W
WARNING
ARNING Risk of burns from hot compo-
nent parts in the engine compartment
Cer tain component parts in the engine com-
partment can be very hot, e.g. the engine, the
cooler and parts of theex haust system. #
Allow the engine tocool down and only
to uch component parts described in the
fo llowing. Coolant contains gl
ycol and is therefore poison-
ous. #
Obser vethe information under "Operating 0u-
ids and capacities" (/ page 277).

NOTE
TEPaintwork damage due tocoolant If coolant
gets on painted sur faces, the paint-
wo rkcan be damaged. #
