General information

This additional user manual contains information and instructions on using your vehicle's pneumatic suspension system.

The pneumatic suspension system is located at your vehicle's rear axle. It consists of air cushions supplied by an electric compressor and an electronic control device (computer and solenoid valves) connected to height position sensors.

The system enables the height of the vehicle's rear axle to be adjusted according to the road type and the vehicle usage conditions. It is continuously adjusted according to the road surface and usage conditions to keep the rear axle at the requested height, regardless of the vehicle's load.

Have the pneumatic suspension system checked and serviced regularly to ensure its longevity. Any work must be carried out by a qualified professional.

warning

When loading the vehicle, never exceed the Maximum Permissible Weight for your vehicle (MMTA). For further information, refer to the vehicle's basic user manual.

System operation

With the engine on, you can use the remote control to:

  • automatically adjust the height of the vehicle's rear axle to three preset positions:
    • high position;
    • standard driving position;
    • low position;

or

  • manually adjust the height of the vehicle's rear axle.

Note:

  • with the ignition on and the engine not running, you can lower the vehicle using the remote control. You can also raise the vehicle if the pressure in the suspensions is sufficient. If the pressure is insufficient, the raising of the vehicle is automatically inhibited;
  • when the ignition is switched off, the system remains active for approximately 30 seconds to lower and/or raise the vehicle (if the pressure is sufficient). Beyond this time period, the system is switched off.
warning

The driver must always be alert to sudden events which may occur when using the system. Always make sure that there are no obstacles present (e.g. no height constraint (presence of a roof), no contact with a pavement kerb or any other obstacle) when altering the height of the vehicle's rear axle.

Risk of damage to the vehicle.

warning

The air suspension system must be deactivated in order to carry out any operation on the vehicle or the suspension, or when connecting an electronic diagnostic system, to avoid damaging the components or injuring people, and when the vehicle is lifted or towed. To deactivate it, activate service mode Service mode.

Position of the headlights

During driving, the headlight beam must remain in the "0" position. For further information, refer to the vehicle's basic user manual.

Special cases of combustion engine vehicles

The pneumatic suspension compressor only works with the engine running or the ignition on and the 12 V battery sufficiently charged.

Special cases of electric vehicles

The pneumatic suspension compressor only works with the ignition on and the traction battery sufficiently charged.
