GWARNING
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on the seat guide rail. There is a risk of injury.
Make sure when adjusting a seat that no one
has any body parts in the sweep of the seat.
GWARNING
If the driver's seat is not engaged, it could
move forwards as far as the next catch during movement such as braking or abrupt changes
of direction. As a result, you would be pushed
against your seat belt by the unsecured driv-
er's seat.
This could cause you to lose control of the
vehicle. The seat belt cannot protect as inten-
ded and could result in additional injury.
There is a risk of an accident and injury.
Before every journey, make sure that the driv-
er's seat is fully engaged.
Observe the safety notes on "Air bags"
(
Ypage 45) and "Children in the vehicle"
(Ypage 56).
GWARNING
If you adjust the seat height carelessly, you or
other vehicle occupants could be trapped and
thereby injured. Children in particular could
accidentally press the electrical seat adjust-
ment buttons and become trapped. There is a
risk of injury.
While moving the seats, make sure that your
hands or other body parts do not get under the
lever assembly of the seat adjustment sys-
tem.
GWARNING
If the head restraints are not installed or not
adjusted correctly, they cannot provide pro-
tection as intended. There is an increased risk
of injury in the head and neck area, e.g. in the event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level.
GWARNING

actual distance from the road users traveling
behind by glancing over your shoulder.
