3 Using the EF-S system
The EF-S system is turned on when the ignition key is placed in the ignition position. First,
thetractor unit’s EBS system is activated. This system then turns on both the EF-S system
and the battery charger. The remote control is turned on via the accessory position and
starts automatically. Various messages are displayed on the remote control’s screen.
NEVER drive with an articulated vehicle whose EF-S system has not
been pressurized!
After the button is pressed, the angular rotation of the wheels of the trailer/semi-trailer
is changed, if necessary, to match the angular rotation of the tractor unit with regard to the
trailer/semi-trailer.
If you forget to press button
, the EF-S system’s operating system is started automatically
as soon as the vehicle’s speed exceeds 2 km/h or if the tractor unit is at an angle to the trail-
er/semi-trailer.
Before pressing the button, make sure there are no people or
animals near the wheels because there is a risk of becoming
trapped!
