Closing the engine hood
-Pull the hood down until the pressure from the struts is
reduced .
- Let the hood
drop down and latch in place. Do not try to
push it shut;
it may fail to engage => &.
& WARNING
A hood that is not completely latched could fly up and block your
view while driving.

safety catch has properly engaged. The hood should be flush with
the surrounding vehicle body parts.

After you switch the engine off, the auxiliary fan can continue running for up to 10 minut es -even with th e igni tion o ff. It can even
switch o n again later by itself~ & , if
• the temperature of the engine coo lant rises due to the heat
bui ld -up from the engine in the engine compartment, o r
• the engine compartment heats up because the vehic le is parked
in intense sun light.
