Rear seat head restraints
GWarning!
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint in such a way that it
is as close to the head as possible and the
center of the head restraint supports the back
of the head at eye level. This will reduce the
potential for injury to the head and neck in the
event of an accident or similar situation.
With a rear seat occupied, make sure to move
the respective head restraint up from the
lowest non-use position and have the
occupant adjust the head restraint properly.
Do not drive the vehicle without the seat head
restraints installed when the rear seats are
occupied. Head restraints are intended to
help reduce injuries during an accident.
GWarning!
Make sure the rear seat head restraints
engage when placing them upright manually.
Otherwise their protective function cannot be
ensured.
The back of the head will not be supported in
the event of a collision. That could cause
serious or even fatal injuries. Rear seat
occupants can be seriously injured or killed.

The folding bench seat in the luggage
compartment is only suitable for persons no
more than 4.6 ft (1.40 m) tall and weighing a
maximum of 110 lb (50 kg).
Maximum permissible passenger weight may
be reduced by extensive optional extras and
vehicle load. Observe the maximum gross
vehicle weight and the gross axle weight
rating, which can be found on the vehicle
