Useful information
i This Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.

ist workshops (Y page 29). Correct driver's seat position
G
WARNING
You could lose control of your vehicle if you do the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine. X
Observe the safety guidelines on seat
adjustment (Y page 105).
X Make sure that seat 0087is adjusted prop-
erly.
Electrical seat adjustment (Y page 106)
When adjusting the seat, make sure that:
R you are as far away from the driver's air bag
as possible.
R you are sitting in a normal upright position.
R you can fasten the seat belt properly.
R you have moved the backrest to an almost
vertical position.
R you have set the seat cushion angle so that
your thighs are gently supported.
R you can depress the pedals properly.
X Check whether the head restraint is adjus-
ted properly.
When doing so, make sure that you have
adjusted the head restraint so that the back of your head is supported at eye level by the
center of the head restraint. Also make
sure that you have adjusted the head
restraint so that the back of your head is as close to the head restraint as possible. Thiswill be the case if the head restraint is
adjusted correctly (Y page 107).
X Observe the safety guidelines on steering
wheel adjustment (Y page 111).
X Make sure that steering wheel 0043is adjus-
ted properly.

Important safety notes
G
WARNING
Children could become trapped if they adjust the seats, particularly when unattended.
There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never leave children unsupervised in the vehicle. G
WARNING
You could lose control of your vehicle if you do the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine. G
WARNING
If you adjust the seat height carelessly, you or other vehicle occupants could be trapped andthereby 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. G
WARNING
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. G
WARNING
If head restraints are not installed and adjus-
ted correctly, they cannot provide protection
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. G
WARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder. G
WARNING
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus, Seats

we strongly recommend that children be
placed in the rear seat whenever possible.
Regardless of seating position, children 12
years old and under must be seated and prop- erly secured in an appropriately sized child
restraint system or booster seat recommen-
ded for the size and weight of the child. For
additional information, see the "Children in
the vehicle" section.
A child's risk of serious or fatal injuries is sig- nificantly increased if the child restraints are
not properly secured in the vehicle and/or thechild is not properly secured in the child
restraint.
! To avoid damage to the seats and the seat
heating, observe the following information:
R keep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as soon as possible.
R if the seat covers are damp or wet, do not
switch on the seat heating. The seat
heating should also not be used to dry
the seats.
R clean the seat covers as recommended;
see "Interior care".
R do not transport heavy loads on the
seats. Do not place sharp objects on the seat cushions, e.g. knives, nails or tools. The seats should only be occupied by
passengers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating mate-
rials, e.g. blankets, coats, bags, seat cov- ers, child seats or booster seats.
! Make sure that there are no objects in the
footwell under or behind the seats when
moving the seats back. There is a risk that
the seats and/or the objects could be dam- aged.
i It is not possible to remove the head
restraints from the front seats. The rear-
compartment head restraints, however,
can be removed (Y page 108). For more information, contact a qualified
specialist workshop.
