Driving and operating101Brakes
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 before
continuing 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.
If control indicator R illuminates in
the instrument cluster while driving and the message BRAKING FAULT
appears in the Driver Information
Centre there is a fault in the braking
system. Seek the assistance of a
workshop immediately.Control indicator R 3 71.
Vehicle messages 3 75.
Antilock brake system Antilock brake system (ABS)
prevents the wheels from locking.
ABS starts to regulate brake pressure as soon as a wheel shows a tendency
to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
Control indicator u 3 72.
Fault If control indicator u does not go out
a few seconds after the ignition is
switched on, or if it illuminates while driving, there is a fault in the ABS.
Control indicator A may alsoilluminate in the instrument cluster
together with the messages CHECK
ABS and CHECK ESP in the Driver
Information Centre. The brake
system remains operational but
without ABS regulation.9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
If control indicators u, A , R and
C illuminate, the ABS and ESP are
deactivated and the message
BRAKING FAULT is shown in the
Driver Information Centre. Seek the
assistance of a workshop.
Have the cause of the fault remedied
by a workshop.

112Driving and operating
For the values specific to your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
General information The official fuel consumption and
specific CO 2 emission figures quoted
relate to the EU base model with
standard equipment.
Fuel consumption data and CO 2
emission data are determined
according to regulation R (EC) No.
715/2007 (in the applicable version),
taking into consideration the vehicle
weight in running order, as specified
by the regulation.
The figures are provided only for the
purpose of comparison between
different vehicle variants and must
not be taken as a guarantee for the
actual fuel consumption of a
particular vehicle.
Additional equipment may result in
slightly higher results than the stated
fuel consumption and CO 2 figures.Furthermore, fuel consumption is
dependent on personal driving style
as well as road and traffic conditions.Trailer hitch
General information
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment. Only use
towing equipment that has been
approved for your vehicle.
Driving characteristics and
towing tips
In the case of trailers with brakes,
attach the breakaway stopping cable.
Before attaching a trailer, lubricatethe coupling ball. However, do not do
so if a stabiliser, which acts on the coupling ball, is being used to reduce snaking movements. For trailers with
low driving stability the use of a
stabiliser is recommended.
A maximum speed of 50 mph must
not be exceeded, even in countries
where higher speeds are permitted.
Driving and operating113
If the trailer starts snaking, drive moreslowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 163.
Trailer towing Trailer loads
The permissible trailer loads are
vehicle and engine-dependent
maximum values which must not be exceeded. The actual trailer load is
the difference between the actual
gross weight of the trailer and the
actual coupling socket load with the
trailer coupled.
The permissible trailer loads are
specified in the vehicle documents. In general, they are valid for gradients
up to max. 12 %.The permitted trailer load applies up
to the specified incline and up to an
altitude of 1000 metres above sea
level. Since engine power decreases
as altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10 %
for every 1000 metres of additional
altitude. The gross train weight does
not have to be reduced when driving
on roads with slight inclines (less than 8 %, e.g. motorways).
The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 150.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load is specified on the
towing equipment identification plate
and in the vehicle documents. Always aim for the maximum load, especiallyin the case of heavy trailers. The
vertical coupling load should never
fall below 25 kg.
In the case of trailer loads of
1200 kg or more, the vertical coupling load should not be less than 50 kg.
Rear axle load When the trailer is coupled and the
towing vehicle fully loaded (including
all occupants), the permissible rear
axle load (see identification plate or
vehicle documents) must not be
exceeded.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
114Driving and operating9Warning
Towing a trailer is permitted only
when a coupling ball bar is fitted correctly. If the coupling ball bardoes not engage correctly, seekthe assistance of a workshop.
Towing equipment audible
warning For vehicles fitted with towingequipment, when connected to a
trailer the pitch of the audible warning
changes upon operation of the turn
signals.
The pitch of the audible warning will
also change if a turn signal light on the trailer or the towing vehicle fails.

Place a container underneath the
filter housing. Loosen the knurled
screws on the filter cover and on the
lower part of the filter by approx. one
turn, to drain off the water.
The filter is drained as soon as diesel fuel emerges from the knurled screw
at the bottom. Retighten the two
screws.
Check diesel fuel filter at shorter
intervals if the vehicle is subjected to
extreme operating conditions.
Diesel fuel system
bleedingIf 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:
1. Remove the protective cover from
the in-line supply pump.
2. Place a suitable container underneath the fuel filter vent
screw to collect fuel.
3. Loosen the vent screw (arrowed) by one turn.
4. Manually operate the in-line supply pump slowly and steadily
until fuel discharging from the
loosened vent screw is free of air
bubbles.

Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
Tyres
Factory-fitted tyres are matched to the chassis and offer optimum driving comfort and safety.
Winter tyres Winter tyres improve driving safety attemperatures below 7 °C and shouldtherefore be fitted on all wheels.In accordance with country-specific
regulations, a notice indicating the
maximum permissible speed for the
tyres must be affixed within the
driver's field of vision.

9. Set the rocker switch on thecompressor to I. The tyre is filled
with sealant.
10. The compressor pressure gauge briefly indicates up to 6 bar(600 kPa/87 psi). Then the
pressure starts to drop.
11. All of the sealant is pumped into the tyre. Then the tyre is inflated.12. The prescribed tyre pressure should be obtained within
10 minutes. Tyre pressure
3 163 . When the correct pressure
is obtained, switch off the
compressor.
If the prescribed tyre pressure is
not obtained within 10 minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation
(approx. 2 metres). Reattach the
tyre repair kit and continue the
filling procedure for 10 minutes. If
the prescribed tyre pressure is still not obtained, the tyre is too badly
damaged. Seek the assistance of
a workshop.
Drain excess tyre pressure with
the button above the pressure
indicator.
Do not run the compressor for
longer than 10 minutes.
13. Detach the tyre repair kit. Screw the tyre inflation hose to the free
connection on the sealant bottle.
This prevents sealant from
escaping. Stow tyre repair kit
under the front seat.
14. Remove any excess sealant using a cloth.
15. Take the label indicating maximum permitted speed from
the tyre repair kit and affix in the driver's field of view.
