Pay attention tothero ad conditions and

Drive carefully. The le
vel of theve hicle depends on vehicle load
and the load distribution. Elect ronic le vel control
adjusts the le vel of there ar axle automatically on
ve hicles with an air-sprung rear axle. The vehicle

le ve l,re ga rdless of vehicle load. Driving dynamics
re main unaf fected. The height dif fere nce
between the sides of theve hicle may be up to
0.4 in (1 cm).
Electronic le vel control is not engine-dependent
and is only operational when the ignition is
switched on. The electronic le vel control com‐
pressor works audibl y.
% If
th e compressor works cons tantly or starts
up se veral times per minute, elect ronic le vel
control is malfunctioning.
Depending on theve hicle equipment, electronic
le ve l control switches between manual and auto‐
matic mode depending on either theve hicle
speed or the position of the parking brake.
If electronic le vel control switches depending on
ve hicle speed, manual operation is automatically
activated when theve hicle is stationar y.Yo u may

qu ently drive faster than 6 mph (10 km/h), man‐
ual mode is automatically deactivated and auto‐

If elect ronic le vel control switches depending on
th e parking brake position, manual mode is auto‐
matically activated when the parking brake is
applied. You may raise or lo werth eve hicle le vel
to load and unload. If youre lease the parking
brake, manual mode is automatically deactivated
and automatic mode sets the driving le vel.
When working on theve hicle or changing a

(/ page 129). If electronic le
