First of all, control the tyre pressure. If it is not correct, reinflation or deflation will be done to reach the
recommended pressure within – 0 bar and + 0.3 bar limits. In every case, this pressure must be balanced.
Move forward the vehicle at low speed, let it stop smoothly (without using the parking brake) on a
levelled and horizontal surface, front wheels in a straight line. By default, it is suitable that the vehicle
runs for at least 1 wheel turn (without any effort for the trains) and to stop it (without using the parking
brake) on a levelled and horizontal surface.
For vehicles with non standard suspension (e.g. : servo suspension), it is necessary to run the engine
before making any measurement, wait for the vehicle to stabilize with the engine running.
Actuate the parking brake (gradually for manual handbrakes).
When the vehicle is equipped, either in the passenger compartment or at the headlamp level, with a
manual setting system, place the device in the position recommended by the manufacturer according to
the charge state. If the system does not work, the control is made in the existing configuration.
