How to adjust and/or reinstall the roll bar sensors

Hi guys,

The process is very simple, all what you have to do is follow the below steps for testing and replacing/adjusting the sensor:

- Testing the roll bar sensor:


Set rotating part (1) on one of the two rear axle switches to "arrested".

Then drive the vehicle to test. The roll-over bar should extend (crash actuation) when the vehicle is braked sharply from a speed of approx. 5-10 km/h . After testing set the rotating part (1) back to "Function".

NOTE: A clicking noise is audible as the roll-over bar extends.


- Replacing the roll bar sensor:

Removal

Roll-over bar
put up with convenience switch
Ignition
switch off
Negative pole on battery
disconnect and cover
Connector for rear axle switch on left (S3/2x) and right (S83/3x)
release by pressing (arrow)
Connectors
disconnect
Nuts (2)
loosen
Rear axle switches (S83/2,S83/3)
remove
Nuts (2)
retighten (4 + 0.5 Nm )

Installation

NOTE: The rear wheels must hang freely (rear axle suspension extended completely)

Rotating part (1) on both rear axle switches
turn to arrested position.
Nuts (2)
unscrew
Rear axle switches on left and right
position on bolts. Tighten nuts (2) hand-tight.
Rear axle switches
grip with hand on lever and position tip (3) against covering (4).
Nuts (2)
tighten (4 + 0.5 Nm ).
Function of roll-over bar
check.
Roll-over bar should actuate. (see the testing above)
Rotating part (1)
turn back to function position.

Hope the above information will help you to fix your problem.
