The hood latch is not locked correctly. Stop im-
mediately and close the hood.

ZA\ WARNING
— Never open the hood when there is steam or

is latched if the front corners cannot be lift-

— If you notice that the hood is not latched
while you are driving, stop immediately and
close it, because driving when the hood is
not latched increases the risk of an accident.
