cident.
If you or other occupants are not wearing
your seat belt, there is a risk of being thrown
out of the opening in the event of the vehicle
overturning. Therefore, always wear a seat
belt to reduce the risk of injuries.
In accidents in which the vehicle overturns,
there is an increased risk of injury even for
occupants who have fastened their seat

be thrust through the opening.
Remove the key from the ignition lock even
if you are only leaving the vehicle for a short
time.
