Active head restraints

In the event of a rear-end impact, the

front parts of the active head

restraints are moved slightly

forwards. Thus the head is supported

Seat position

9 Warning

Only drive with the seat correctly

adjusted.

9 Warning

Never adjust seats while driving as

they could move uncontrollably.

9 Danger

Do not sit closer than 25 cm to the

steering wheel, to permit safe

airbag deployment.

9 Warning

Never store any objects under the

seats.

● Sit with buttocks as far back

against the backrest as possible.

Adjust the distance between the

seat and the pedals so that legs

are slightly angled when pressing

the pedals. Slide the front

passenger seat as far back as

possible.

● Set seat height high enough to

have a clear field of vision on all

sides and of all display

instruments. There should be at

least one hand of clearance

between head and the roof

frame. Your thighs should rest

lightly on the seat without

pressing into it.

● Sit with shoulders as far back

against the backrest as possible.

Set the backrest rake so that it is

possible to easily reach the

steering wheel with arms slightly

bent. Maintain contact between

shoulders and the backrest when

turning the steering wheel. Do

not angle the backrest too far

back. We recommend a

maximum rake of approx. 25°.

● Adjust seat and steering wheel in

a way that the wrist rests on top

of the steering wheel while the

arm is fully extended and

shoulders on the backrest.

Seat belts

The seat belts are locked during hard

acceleration or deceleration of the

vehicle, holding the occupants in the

seat position. Therefore the risk of

injury is considerably reduced.

9 Warning

Fasten seat belt before each trip.
In the event of an accident, people

not wearing seat belts endanger

their fellow occupants and

themselves.

Seat belts are designed to be used by

only one person at a time. Child

restraint system 3 55.
Periodically check all parts of the belt

system for damage, soiling and

proper functionality.
Have damaged components

replaced. After an accident, have the

belts and triggered belt pretensioners

replaced by a workshop.

9 Warning

The openings in the backrests of

the OPC seats are not designed to

mount or carry through any kind of

additional seat belts.

Front seats are equipped with a seat

belt reminder, indicated for driver seat

by control indicator X in the

tachometer 3 87 and for passenger

seat by the control indicators in the

centre console 3 84.

Belt force limiters

On the front seats, stress on the body

is reduced by the gradual release of

the belt during a collision.

Belt pretensioners

In the event of a head-on or rear-end

collision of a certain severity, the front

seat belts are tightened.

9 Warning

Incorrect handling (e.g. removal or

fitting of belts) can trigger the belt

pretensioners.

Deployment of the belt pretensioners

is indicated by continuous illumination

of control indicator v 3 87.

Triggered belt pretensioners must be

replaced by a workshop. Belt

pretensioners can only be triggered

once.

Note

Do not affix or install accessories or

other objects that may interfere with

the operation of the belt

pretensioners. Do not make any

modifications to belt pretensioner

components as this will invalidate

the operating permit of your vehicle.

Fasten

Withdraw the belt from the retractor,

guide it untwisted across the body

and insert the latch plate into the

buckle. Tighten the lap belt regularly

Airbag system

The airbag system consists of a

number of individual systems

depending on the scope of

equipment.
When triggered, the airbags inflate

within milliseconds. They also deflate

so quickly that it is often unnoticeable

during the collision.

9 Warning

The airbag system deploys in an

explosive manner, repairs must be

performed by skilled personnel

only.

9 Warning

Adding accessories that change

the vehicle's frame, bumper

system, height, front end or side

sheet metal, may keep the airbag

system from working properly. The

operation of the airbag system can

also be affected by changing any

parts of the front seats, seat belts,

airbag sensing and diagnostic

module, steering wheel,

instrument panel, inner door seals

including the speakers, any of the

airbag modules, ceiling or pillar

trim, front sensors, side impact

sensors or airbag wiring.

Note

The airbag systems and belt

pretensioner control electronics are

located in the centre console area.

Do not put any magnetic objects in

this area.
Do not affix any objects onto the

airbag covers and do not cover them

with other materials. Have damaged

covers replaced by a workshop.
Each airbag is triggered only once.

Have deployed airbags replaced by

a workshop. Furthermore, it may be

necessary to have the steering

wheel, the instrument panel, parts of

the panelling, the door seals,

handles and the seats replaced.

Front airbag system

The front airbag system consists of

one airbag in the steering wheel and

one in the instrument panel on the

Additionally, there is a warning label

on the side of the instrument panel,

visible when the front passenger door

is open, or on the front passenger sun

visor.
The front airbag system is triggered in

the event of a front-end impact of a

certain severity. The ignition must be

switched on.

The inflated airbags cushion the

impact, thereby reducing the risk of

injury to the upper body and head of

the front seat occupants

considerably.

9

Warning

Optimum protection is only

provided when the seat is in the

proper position.

injury to the head in the event of a

side-on impact considerably.

9 Warning
