It is recommended to place the child seat in the rear area if

possible.

If, in exceptional cases, the owner wishes a rearward mounted child
seat to be expressly attached on the front passenger seat, the front

passenger airbag should be immobilized.


As a general rule, there is no approval for immobilizing the front

passenger airbag on models fitted with ACSR, which is visible from

the "airbag OFF" indicator light in the center console. On such

models, an MB child seat with ACSR should be used for safety and

cost reasons.

-----------------------------------------------------------------------------------------


On models fitted with seat belt force limiter, it is essential for

safety reasons to

D
program the front passenger ETR to "NO".

D
unplug the connector at the front passenger ETR.


No provision is made for immobilizing the seat occupied

recognition, the automatic child seat recognition (ACSR), as well as

the side airbag and window airbag.

In the event that it is necessary to immobilize the seat occupied

recognition and automatic child seat recognition (ACSR), for example

if a Recaro seat is installed, this can be carried out in exceptional

cases after agreement has been obtained from GSP/SPS, tel. 07031

/ 90 - 81815.

-----------------------------------------------------------------------------------------


After immobilizing the front passenger airbag or additionally the

ETR, it is essential to

D
have the customer sign the confirmation after immobilization.

D
affix a sticker at a clearly visible point in the area of the front

passenger airbag.

D
affix a sticker in the Owner's Manual, in the section Airbag.

Carry out the remaining procedure as stated below.

-----------------------------------------------------------------------------------------
Deactivation can be reversed at any time.

Immobilization and re-activation must be entered in the

vehicle documents!

The vehicle should be presented in such a case to a technical

inspection center (DEKRA, TÜV). The completed confirmation

should be submitted to the vehicle registration authorities for

entry.

Installation:
Push on fanfare horns and

airbag clock spring contact (A45) as far as the

stop. In the process the recess must align

with the fixing lug (arrow)

contact (A45) for damage

Visual inspection

Do not use any oil or grease!

The upper (32f) and lower part (32g) of

the clock spring contact are clipped together

and can only be separated by the effect of

high forces or due to defective assembly. If

the spring contact is assembled incorrectly,

carefully unwind and clip the upper and lower

parts together. Be careful not to trap or bend

the spring contact (32e).
