218 Driving and operation
The vehicle is automatically raised at the
rear, increasing the spring travel and
ground clearance.
The automatic level control system is
activated after approx. 1.9 miles (3 km),
depending on the vehicle loading and the
nature of the road surface.
Headlight range adjustment, see
page 146.
On function faults, do not utilise full load
capacity. Have the cause of the fault
eliminated immediately by a workshop.
Deflation detection system
(DDS = Deflation Detection System) 3
The deflation detection system
continuously monitors the speed of all
wheels while driving. If a tyre loses
pressure, it grows smaller and rotates more
quickly than the other wheels. If the system
detects a difference in speed, control
indicator
w illuminates red.
Stop immediately and check tyre pressure.
Mount the spare wheel if necessary, see
pages 249, 252.
The system is operational when the ignition
is switched on and can detect pressure loss
from a speed of 20 mph (30 km/h).
