WARNING

Observe the safety precautions for pyrotechnical components.

Refer 

to

⇒ “1.2 Safety Precautions for Pyrotechnic Components”, page

3

 .

There is a risk of injury if the engine starts automatically in ve‐

hicles with the Start/Stop System.

♦ For vehicles with an activated Start/Stop system (recog‐

nized by a signal in the instrument cluster), the engine can

be started automatically if needed.

♦ Make sure that the Start/Stop System is disabled when

working on the vehicle (turn off ignition, if needed, turn the

ignition back on).

– Disconnect the battery ground cable with the ignition turned

on. Refer to ⇒  Electrical Equipment; Rep. Gr.  27 ; Battery;

Battery, Disconnecting and Connecting .

– Open the hood.
– If necessary, remove the air filter housing. Refer to ⇒  Rep.

Gr.  23 ; Air Filter or ⇒  Rep. Gr.  24 ; Air Filter .

– Disengage the washer fluid reservoir filler tube from the sup‐

port. Refer to ⇒  Electrical Equipment; Rep. Gr.  92 ; Wind‐

shield Washer System; Washer Fluid Reservoir, Removing

and Installing .

– Remove the screw -2- and the front airbag crash sensor -1-

from the lock carrier.

WARNING

Before  handling  pyrotechnic  components  (for  example,  dis‐

connecting the connector), the person handling it must “dis‐

charge static electricity”. This can be done by touching the door

striker pin, for example.

– Disconnect the connector -3-.

– To do this pull out the connector lock -2- and push down in

direction of -arrow-, disconnect the connector -1- on the crash

sensor.

Installing

WARNING

♦ Observe the safety precautions for pyrotechnical compo‐

nents. Refer to

⇒ “1.2 Safety Precautions for Pyrotechnic Components”,

page 3

 .

♦ Before handling pyrotechnic components (for example,

connecting the connector), the person handling it must

“discharge static electricity”. This can be done by touching

the door striker pin, for example.

– Connect the connector -1- to the crash sensor until it clicks into

place -arrow-.

– Push in the connector lock -2- to secure the connector.
Installation is performed in reverse order of removal, while noting

the following:

Note

♦

Make sure the connectors are pushed in all the way and that

they engage audibly.

♦

Make sure the wires are not pinched.

WARNING

The ignition must be on when connecting the battery. If pyro‐

technic components (for example, airbag, belt tensioner) are

not repaired correctly, they may deploy unintentionally after

connecting battery. There must not be anyone inside the ve‐

hicle when connecting the battery.

– Connect the battery ground cable with the ignition turned on.

Refer to ⇒  Electrical Equipment; Rep. Gr.  27 ; Battery; Bat‐

tery, Disconnecting and Connecting .

WARNING

If the ignition is not switched on after the battery is reconnected

- “indicator lamps in the instrument cluster do not light up” - the

ignition (key/button) may only be switched on when the driver

seat is positioned all the way back.

Note

If the Airbag Indicator Lamp - K75- indicates a fault, check the

DTC memory, erase it and check it again using the Vehicle Di‐

agnostic Tester .
