an accident and injure yourself or others.
For this reason, remove the wind screen as
soon as it is dark or if your vision is otherwise
restricted.
GWARNING
If the wind screen is not correctly engaged, it
may break free and thus obstruct traffic
behind you or lead to an accident.
Each time before driving with the roof down,
check that the wind screen is properly
engaged.
! Install or remove the wind screen only
when the roof is open. You could otherwise
damage the wind screen or the vehicle
