Using electronic level control for charging
with air in an emergency
*
NOTE Damage due to pressure being too
high
If the pressure in the air suspension bellows
is too high, the compressed-air lines or the air
suspension bellows may be damaged.
#
Ensure you observe the maximum per‐
missible operating pressure of 900 kPa
(9 bar/130 psi).
Only for vehicles with valves for electronic level
control emergency charging. If electronic level
control is malfunctioning and the vehicle is lean‐
ing, you can raise or lower the vehicle by con‐
necting an external compressed-air source to one
of the emergency valves (similarly as with tire
valve). If electronic level control is not opera‐
tional, you can drive on carefully to the nearest
qualified specialist workshop and have the mal‐
function remedied.
#
Apply the parking brake.

Vehicles with automatic transmission:
shift the transmission to position
j
.
#
Switch off the engine.
#
Turn the valve cap of the corresponding valve
(

R = right).
#
Connect the external compressed-air source.
#
Raise or lower the vehicle level by charging or
releasing compressed air until the driving
level has been reached and the vehicle is in a
horizontal position. While doing so, ensure
you observe the maximum permissible oper‐
ating pressure of 900 kPa (9 bar/130 psi).
#
Disconnect the external compressed-air
source.
#
Tighten the valve cap on the valve (

Drive on carefully to the nearest qualified
specialist workshop.
