Check the reservoir pressure in the
compressed-air brake system.

the condensation.
#
If a large amount of condensation runs out,
have the compressed-air brake system
checked at a qualified specialist workshop.
Vehicles with condensation monitoring:
If the system detects that the number of regener‐
ation phases performed is insufficient, the yellow

Condensation in compressed-air reservoir
event window is displayed in the instrument clus‐

WARNING Risk of accident due to low‐
ered or raised chassis
Vehicles with level control system: driving
with a lowered or raised chassis may greatly
impair braking and handling characteristics.
Additionally, the maximum permitted vehicle
height may be exceeded when the chassis is
raised.
#
Set the driving level before pulling away.
If the yellow
¸
indicator lamp lights up in the
instrument cluster, the chassis is not at driving
level.
#
Set the driving level (

page 263).
The
¸
indicator lamp goes out in the
instrument cluster.
Notes on pulling away
*
NOTE Damage due to oil pressure being
too low
The engine needs a short time to build up the
necessary oil pressure after starting, espe‐
cially if it is cold.
There is a risk of increased wear and engine
damage if the oil pressure is insufficient.
#
Before driving off or increasing the
engine speed, let the engine run in neu‐
tral for a short time.
#
Avoid high engine speeds if the engine
is cold.
*
NOTE Overloading power-steering
Damage or malfunctions may be caused to
the steering by holding the steering wheel at
the steering stop for too long or turning the
steering wheel too forcefully, e.g. if the
wheels are resting on the curb.
#
Do not hold the steering wheel on full
lock for longer than ten seconds.
#
Do not turn the steering wheel too
forcefully if the wheels are resting on an
object.
You should pay special attention to road condi‐
tions when temperatures are around freezing
point.
Changes in the outside temperature will be dis‐
played after a short delay.
Vehicles with an automated manual transmission
and without a fluid coupling: the vehicle has a
selectable crawler mode. When crawler mode is
activated, the vehicle automatically crawls for‐
wards after the service brake has been released
and continues to roll at idling speed. You can find
information on crawler mode in the "Automated
manual transmission" section (
/
page 218).
Vehicles with a fluid coupling: always pay atten‐
tion to the information about pulling away in the
"Fluid coupling" section (
/
page 226).
