BODY EXTERIOR | Air Jack System
Do not use mineral oil containing care/cleaning agents for the air
jacks. This can damage the seals. Only silicone grease or sprays con-
taining silicone are permitted. Check the air jacks regularly for mecha-
nical damage.
NOTE
The raised vehicle can be lowered slowly and in a controlled manner
using a plunger in the drain valve. This function is useful to lower the
vehicle slowly (e.g. on a weighing sclaes).
NOTE
The drain valve must be open (pulled out) while driving in order to en-
sure that the air jacks are retracted completely and to prevent the
jacks from being inadvertently removed when the system heats up.
NOTE
NOTE
If the optionally available "Autostart" function is ordered, the vehicle
can be started automatically when the vehicle is lowered using a pres-
sure sensor in the line system of the lifting system.
The wiring loom is already prepared for the connection of such a sen-
sor (connector in the trunk area with the label "sensor_pres_airjack").
The starter is controlled via the ICD and IPS configuration.
As standard, the connection is closed with a threaded plug. As part of
the maintenance work, the screw plug should be checked for
tightness.
Runtime - related servicing of the air jacks can be carried out by KRON-
TEC Maschinenbau GmbH.
