Using electronic levelcontrol forcharging
with air in an emergency
*
NOTE Damage due to pressurebeing too
high
If thepressureinthe air suspension bellows
is toohigh, thecompressed-air lines or theair
suspension bellows maybedamaged.

Ensureyou observe themaximum per‐
missible operating pressureof900 kPa
(9 bar/130 psi).
Onlyfor vehicles withvalves forelectronic level
control emergency charging. If electroniclevel
control is malfunctioning and thevehicle is lean‐
ing, youcan raise or lowerthe vehicle by con‐
necting an external compressed-air source to one
of theemergency valves (similarly as with tire
valve).Ifelectronic levelcontrol is notopera‐
tional, youcan driveoncarefullytothe nearest
qualified specialistworkshop and have themal‐
function remedied.

Apply theparking brake.
#
Vehicles with automatic transmission:
shiftthe transmission to position j.
#
Switchoff theengine.
#
Turn thevalvecap of thecorresponding valve
(1 L=left, 2 R=right).
#
Connectthe external compressed-air source.
#
Raise or lowerthe vehicle levelbycharging or
releasing compressed air until thedriving
levelhas been reached and thevehicle is in a
horizontal position. While doing so, ensure
youobservethe maximum permissible oper‐
ating pressureof900 kPa(9bar/130 psi).
#
Disconnectthe external compressed-air
source.
#
Tighten thevalvecap on thevalve(1L=
