232Driving and operatingl:lowered positionk:normal positionj:raised positionCaution
If an obstacle is detected while
raising or lowering, the
suspension height is returned to the normal position after a delay.
This does not guarantee damage- free operation. Ensuring sufficient
clearance and freedom from
obstacles is the responsibility of the driver.
Manual settings
Manual adjustment can only be
performed when the vehicle is
stationary.
Select by pressing h for 2 seconds,
then R to raise, or S to lower.
To exit, press any of the pre-
programmed buttons.
Notice
Obstacle detection is not available
during manual adjustment.
When a certain low speed is
exceeded or when the ignition is
switched off, height adjustment is deactivated automatically and the
suspension height is returned to the
normal position.
Service mode
When the vehicle is stationary, press
i for 5 seconds to put the vehicle into
service mode. The indicator light will
illuminate.
When service mode has been
activated, the air suspension master
switch must be turned off.
To exit service mode, press i again
for 5 seconds.
Fault
If a fault is detected, i will flash
intermittently. If service mode has been activated and there is a fault, h,
S and R will flash simultaneously.
Have the cause of the fault remedied
by a workshop.Engine exhaust9 Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The diesel particle filter system filters
soot particles out of the exhaust
gases. The system includes a self-
cleaning function that runs
automatically during driving without
any notification.
The filter is cleaned by periodically
burning off the soot particles at high
temperature. This process takes
place automatically under set driving
Driving and operating243It is possible to use the Laden mode
in both manual and automatic modes.
In both cases, the gearshifting
patterns are adapted automatically
for carrying an increased payload.
Activation
Press kg. Control indicator kg is
shown in the transmission display.
The transmission will then select
optimized gearshift patterns.
Deactivation
The Laden mode is switched off by:
● pressing kg again
● turning off the ignition
Kickdown If the accelerator pedal is pressed
past the pressure point, the
transmission shifts to a lower gear depending on engine speed. Full
engine power is available for
acceleration.
If engine speed is too high the
transmission switches to a higher
gear, even in manual mode. Without
kickdown this automatic shift is not
effected in manual mode.Fault
In the event of a fault, control indicator W is shown in the transmission
display. Continued driving is possible
provided the vehicle is driven with care and anticipation.
Have the cause of the fault remedied
by a workshop.
Interruption of power supply The clutch is not disengaged if there
is an interruption of the power supply
when a gear is engaged. The vehicle
cannot move.
If the vehicle battery is discharged,
start the vehicle using jump leads
3 303.
If the cause of the fault is not a
discharged vehicle battery, seek the
assistance of a workshop.
If neutral cannot be selected, the
vehicle must only be towed with the drive wheels raised off the ground
3 305.
Towing the vehicle 3 305.Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when you depress the
brake pedal firmly. You need to use considerably more force for this. The
braking distance is extended. Seek the assistance of a workshop beforecontinuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has
been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 99.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.
Driving and operating251Switching on the system
Press U, control indicator U
illuminates yellow in the instrument
cluster.
Speed limiter function is now in
standby mode and a corresponding
message appears in the Driver
Information Centre.
Accelerate to the desired speed and
press < or ]. The current speed is
recorded.
The vehicle can be driven normally
but it will not be possible to exceed the programmed speed limit except in an
emergency.
Where the limit speed cannot be
maintained, e.g. when driving on a
steep decline, the limit speed will
flash in the Driver Information Centre.
Increase limit speed
The limit speed can be increased
continuously or in small increments
by holding down or tapping <
repeatedly.
Reduce limit speed
The limit speed can be decreased continuously or in small increments
by holding down or tapping ]
repeatedly.
Exceeding the limit speed
In the event of an emergency it is
possible to exceed the limit speed by
depressing the accelerator pedal
firmly beyond the point of resistance.
The limit speed will flash in the Driver
Information Centre during this period.
Release the accelerator pedal andthe speed limiter function is
reactivated once a speed lower than
the limit speed is obtained.
Speed warning 3 103.
Vehicle care275Warning label
Meaning of symbols:● No sparks, naked flames or smoking.
● Always shield eyes. Explosive gases can cause blindness or
injury.
● Keep the vehicle battery out of reach of children.
● The vehicle battery contains sulfuric acid which could cause
blindness or serious burn
injuries.
● See the Owner's Manual for further information.
● Explosive gas may be present in the vicinity of the battery.
Additional battery
Depending on the vehicle's auxiliary
equipment, certain models may have
an additional battery mounted under
the right-hand front seat.
Notice
The additional battery is
automatically connected to the main vehicle battery only when the engine
is running. It does not need to be
manually disconnected before
disconnecting the main vehicle
battery or before jump starting the vehicle.
The terminals are designed for
additional electrical consumers up to
a maximum of 50 A.
Jump starting 3 303.
Diesel fuel system bleeding If the fuel tank has been run dry, it will
be necessary to air vent or bleed the
diesel fuel system.
Fill the tank with fuel and proceed as
follows:Caution
Do not turn ignition key to position 3 before beginning the bleeding
procedure.
Ignition switch positions 3 225.
1. Turn ignition key to position 2 and
wait for a few minutes.
2. Turn key back to position 1 and
wait for 3 seconds.
3. Turn key to position 3.
296Vehicle care
7.Screw the sealant filler hose to the
tyre valve.
8. The rocker switch on the compressor must be set to
position O.
9.
Connect the red < power supply
lead on the compressor to the
jump start terminal 3 303.
Notice
Depending on model, the jump start
terminal may be located at the left-
hand or right-hand side of the engine
compartment.
10. Connect the black ] power
supply lead to a vehicle grounding
point, e.g. the engine block or an
engine mounting bolt.
Notice
Depending on tyre repair kit type, it
may be necessary to connect the
single power supply lead to the
power outlet or cigarette lighter
socket.
For this type, the red < and
black ] power supply leads will not
be present.
To avoid discharging the battery,
we recommend running the
engine.
11. Set the rocker switch on the compressor to position I. The tyre
is filled with sealant.
12. The compressor pressure gauge briefly indicates up to 6 bar. Then
the pressure starts to drop.
13. All of the sealant is pumped into the tyre. Then the tyre is inflated.
