Product description
VB-FullAir is a fully automatic, electronically-controlled air suspension system for light commercial
vehicles, motorhomes and special vehicles. The electronic control system ensures that the vehicle
maintains the same ride-height in any load situation. The ride-height is controlled by height sensors
mounted between the chassis and the axle. Height control is always active after switching on the
ignition or during the extra time.
Manual operation for raising or lowering the vehicle can be activated in two ways. This depends on
the option supplied to you.
Depending on the available spring travel, the vehicle can be levelled when at a standstill
using the AutoLevel function.
The automatic level control on the VB-Airsuspension system cannot prevent damage to the
vehicle or superstructure due to overload.
Always make sure the vehicle is not overloaded. When using the air suspension system,
overloading is not visible. If you are in any doubt, VB-Airsuspension advises that you weigh the
axles before driving the vehicle.
Use
Safety rules
“Read and follow all the safety instructions. This is important for your own safety.”
Note:
To be able to use the vehicle functions effectively, the various vehicle components need to
be run in for several kilometres. Minor side effects may be experienced when the vehicle
first driven.
For example, the expected levels of comfort may not be immediately apparent or noises may
be heard.
Never drive the vehicle with a setting other than ride height or SPORT, except with caution and
at a speed not exceeding approximately 30 km/h. Otherwise, the chassis or air suspension
system will become damaged.
Before raising or lowering the vehicle when at a standstill:
Secure the vehicle against rolling away.
Make sure there is no possibility of injury or damage to people and property.
Do not depress the brake pedal (if possible) while raising or lowering the vehicle.
This is advisable to relieve the brake and avoid tension in the chassis.
Always use a jack or hydraulic ramp to change a wheel or carry out servicing work.
Before raising one or more axles with a jack or hydraulic ramp, switch off the air suspension
system using the SERVICE button.
The air suspension must not be used to lift wheels off the ground during servicing work
(to change a wheel for example).
Errors and/or faults in the air suspension system can have an undesirable effect on the driving
stability. This may cause the vehicle to sway and/or swing.
When using snow chains, do not allow the vehicle to fall below the ride-height.
Note:
The built-in air suspension system must not be modified.
Risk of damage!
In case of damage or faults that cannot be rectified, press the SERVICE button to
deactivate the system. Contact an approved VB-partner immediately.
The check light comes on to indicate a fault. If this happens, drive extra carefully and at much
lower speed.
Removing the fuses deactivates the system.
The VB-Airsuspension system improves the suspension and automatically controls the height of the
front and rear axles on the chassis.
Improper use can have undesirable consequences. VB-Airsuspension is not liable for any resulting
damage.

The air suspension system is ready for use when you switch on the ignition.
While driving, the control functions are limited or unavailable. In such situations, the safe
ride-height is controlled automatically.
When raising or lowering with the handbrake on, tension or noises may occur in the vehicle.
If you then release the handbrake, there may be unexpected, slight up-and-down movements.
