Roof
Important safety notes
GWARNING
If you do not fully open/close the soft top, the
soft-top hydraulics depressurize after ashort
time. This causes the soft top to lower unex-
pectedly and may cause you or others to be
trapped. There is arisk of injury.
Always open or close the soft top completely.
GWARNING
Closing the roof manually is acomplicated
and technically demanding procedure, which
requires alot of strength. You or others can
become trapped. There is arisk of injury.
Only have the soft top closed manually at a
qualified specialist workshop.
!Never sit on the rear shelf or store heavy
object sthere. You will otherwise damage the
roof and the rear shelf of your vehicle.
!Do not forget that the weather can change
abruptly. Make certain that the roof is closed
when you leave the vehicle. The vehicle elec-
tronics can be damaged if water enters the
vehicle interior.
!When opening and closing the roof, make
sure that:
Rthere is sufficient clearance, as the roof
swings upwards.
Rthere is sufficient clearance behind the
vehicle, as the trunk lid swings backwards
beyond the bumper.
Rthe trunk is only loaded to below the trunk
partition.
Rthe trunk partition is not pushed up by the

Crash-responsive EASY-EXIT feature
If the crash-responsive EASY-EXIT feature is trig-
gered in an accident, the steering column will
move upwards when the driver's door is opened.
This occurs irrespective of the position of the
SmartKey in the ignition lock. This makes it eas- ier to exit the vehicle and rescue the occupants.
