Removing

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.
– 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 in direction of -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 .

♦ Observe the safety precautions for pyrotechnical compo‐

nents. Refer to

⇒ “1.2 Safety Precautions for Pyrotechnic Components”,

page 3

 .

♦ Observe the safety precautions for front side airbag crash

sensors (pressure sensors). Refer to

⇒ “1.6 Front Side Airbag Crash Sensors (Pressure Sen‐

sors) Safety Precautions”, page 7

 .

– Disconnect the battery ground cable with the ignition turned

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

Battery, Disconnecting and Connecting .

– Remove the front door trim panel. Refer to

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.

– Pull out the connector lock -2- and push down in direction of

-arrow-, disconnect the connector -1- on the crash sensor.

– Release the locking mechanism -2- and turn the retainer -1-

for the crash sensor approximately 45° counterclockwise in

direction of -arrow-.

– Disengage the side airbag crash sensor -3- from the door and

remove.

Installing

WARNING

For proper crash sensor (pressure sensor) function, ensure

door does not leak.

– Pay attention that the seal -2- is seated correctly. Replace

crash sensor if damaged or deformed

– Engage the side airbag crash sensor in the door.
– Turn the locking mechanism -1- for the crash sensor clockwise

in direction of -arrow-.
