Important safety notes

WARNING

When driving with a lowered or raised chassis frame, the driving and braking characteristics may be seriously affected. A raised chassis frame may also exceed the permissible vehicle height. There is a risk of an accident.

Set the driving level before pulling away.

Observe the legal requirements on permissible vehicle heights for the country in which you are driving.

Raise or lower the chassis frame to pick up or set down demountable bodies or semitrailers.

If you wish to continue the journey after the chassis height has been modified, raise or lower the chassis to the driving level.

If the nfz_fr_inv_00b8.png indicator lamp in the instrument cluster lights up, the chassis is not at driving level or Telligent® level control is malfunctioning.

Apply the parking brake.

Turn the key to the drive position in the ignition lock.

NR automatically adjusts the chassis frame to the previously stored height.

The chassis frame is raised or lowered at the front or rear axle.

Vehicles with an air-sprung rear axle: the chassis frame is raised or lowered at the rear axle.

If the charge pressure in the compressed-air system is too low, leave the engine running.

The compressed-air system is charged.

Raising/lowering the chassis frame

../../../../global/pictures_mb/symb_achtung.png

WARNING

People's limbs may become trapped if they are located underneath the vehicle or between the vehicle body and the tyres when the vehicle is lowering. There is a danger of injury.

When lowering the vehicle, make sure no one is underneath the vehicle or in the immediate vicinity of the wheel arches.

Press button mbsymb6_inv_003f.png or mbsymb6_inv_0041.png.

Corresponding indicator lamp mbsymb6_inv_003b.png or mbsymb6_inv_003d.png lights up.

To raise the front and rear of the chassis frame on vehicles with full pneumatic suspension, press buttons mbsymb6_inv_003f.png and mbsymb6_inv_0041.png at the same time.

Indicator lamps mbsymb6_inv_003b.png and mbsymb6_inv_003d.png light up.

Press button mbsymb6_inv_0045.png to raise the chassis frame or button mbsymb6_inv_0046.png to lower it.

The mbsymb1a_inv_00da.png or mbsymb1a_inv_00db.png symbol and the Level outside of drive position message are shown in the display. At the same time, the status indicator lights up yellow.

The mbsymb1a_inv_00ef.png indicator lamp also lights up in the instrument cluster.

Once the desired height is reached, press button mbsymb6_inv_0047.png.

Storing/calling up the chassis frame height

Buttons mbsymb6_inv_0042.png and mbsymb6_inv_0043.png can each be used to store a chassis frame height.

To store: raise/lower the chassis to the desired height.

Once the desired height is reached, press and hold button mbsymb6_inv_0047.png and also press button mbsymb6_inv_0042.png or mbsymb6_inv_0043.png.

The current chassis frame height is stored under corresponding button mbsymb6_inv_0042.png or mbsymb6_inv_0043.png.

To call up: press button mbsymb6_inv_003f.png or mbsymb6_inv_0041.png.

Corresponding indicator lamp mbsymb6_inv_003b.png or mbsymb6_inv_003d.png lights up.

Press button mbsymb6_inv_0042.png or mbsymb6_inv_0043.png.

The chassis frame is automatically raised or lowered to the stored height.

The mbsymb1a_inv_00da.png or mbsymb1a_inv_00db.png symbol and the Level outside of drive position message are shown in the display. At the same time, the status indicator lights up yellow.

The mbsymb1a_inv_00ef.png indicator lamp also lights up in the instrument cluster.

Activating the driving level

Press the mbsymb6_inv_0044.png button.

Indicator lamp mbsymb6_inv_003b.png or mbsymb6_inv_003d.png goes out. The chassis frame is raised or lowered automatically to the driving level. Once the chassis frame is at driving level, the mbsymb1a_inv_00da.png or mbsymb1a_inv_00db.png symbol in the display and the status indicator go out.

The mbsymb1a_inv_00ef.png indicator lamp in the instrument cluster goes out.

Loading and unloading the vehicle

../../../../global/pictures_mb/symb_ruf.png

Before removing the demountable body, lower the chassis frame completely. Otherwise, the chassis frame could spring up suddenly when the special-purpose body is removed. This could damage the shock absorbers.

Store a constant chassis frame height for loading and unloading the vehicle.

Vehicles with a leading axle/trailing axle: lower the leading axle more or trailing axle more.

If required, raise/lower the chassis to the desired height.

Run the engine until the pressure regulator cuts out.

Press and hold button mbsymb6_inv_0047.png.

Switch off the engine.

Turn the key back in the ignition lock as far as it will go.

Release button mbsymb6_inv_0047.png.

If there is sufficient supply pressure in the compressed-air system, the height of the chassis frame is kept constant for approximately 4 to 5 hours.

Raised vehicle level (vehicles for large-capacity transport)

images/img0df33f5fdc24305f351f191437348c7f_1_--_--_JPG72.jpg

Axle load measuring device

General notes

When the chassis is at driving level, the axle load measuring system determines the axle load from the pressure in the air spring bellows.

../../../../global/pictures_mb/symb_info.png

The axle load measuring device is not calibrated nor is it a system capable of calibration. The measured data only provides an approximate guide which is not suitable for official use.

In order to avoid inaccuracies when measuring, make sure that the vehicle is uniformly laden.

If you call up the axle load indicator and the chassis is set to driving level, the mbsymb1a_inv_00ef.png indicator lamp flashes. The display shows mbsymb1a_inv_0072.png Axle load display: not possible and Set vehicle level.

Park the vehicle on a level surface.

Engage the parking brake.

Raise or lower the chassis to the driving level more.

Switch off the starting-off aid more.

Drive the vehicle onto the single axle weighbridge.
