Driving and operating153Interruption of power supplyThe 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
3 212.
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
3 214.
Towing the vehicle 3 214.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 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.
Control indicator R 3 97.
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 97.
Fault
If control indicators u and A
illuminate with the messages CHECK
ABS and CHECK ESP in the Driver
Information Centre, there is a fault in
the ABS. The brake system remains
operational but without ABS
regulation.
Driving and operating155Brake assistIf the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking
is required. Maximum brake force is
automatically reduced when the
brake pedal is released.
Brake assist is not available during an
Autostop. Stop-start system 3 135.
Hill start assist The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline (with the
selector lever in a forward gear or
reverse gear), the brakes remain on
for a further two seconds. The brakes release automatically as soon as the
vehicle begins to accelerate.Caution
The Hill start assist cannot
completely prevent vehicle
movement in all situations
(extremely steep gradients, etc.).
If necessary, depress the brake
pedal to prevent the vehicle from
rolling backwards.
The Hill start assist is not active
during an Autostop. Stop-start system 3 135.
Ride control systems
Traction Control system The Traction Control system (TC) is a
component part of the Electronic
Stability Program (ESP® Plus
) which
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational as soon as the
ignition is switched on and control
indicator b extinguishes in the
instrument cluster. A corresponding message also appears in the Driver
Information Centre 3 101.
When TC is active b flashes.
170Driving and operatingTrailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Entrust fitting of towing equipment at
a later date to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Driving characteristics and towing tips
In the case of trailers with brakes,
attach the breakaway stopping cable.
Before attaching a trailer, lubricate
the coupling ball. However, do not do so if a stabiliser, which acts on thecoupling 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.If the trailer starts snaking, drive more slowly, 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 3 244.
Trailer towing
Trailer loads The permissible trailer loads are
vehicle-dependent 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 sealevel. 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
3 223.
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, especially in the case of heavy trailers. The
vertical coupling load should never
fall below 25 kg.

180Vehicle careBrakesIn the event of minimum thickness of
the brake lining, a squealing noise
sounds during braking.
Continued driving is possible but
have the brake linings replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake fluid9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.
The brake fluid level must be betweenthe MIN and MAX marks.
When topping up, ensure maximum cleanliness as contamination of the
brake fluid can lead to brake system
malfunctions. Have the cause of the
loss of brake fluid remedied by a
workshop.
Only use brake fluid approved for
your vehicle.
Brake and clutch fluid 3 220.
Vehicle battery
The jump start terminal is located in
the engine compartment.
Jump starting 3 212.
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
Control indicator p illuminates if
there is a fault with the charging
system. Stop, switch off engine and
seek the assistance of a workshop.
Charging system 3 96.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
four weeks can lead to battery
discharge. Disconnect the clamp from the negative terminal of the vehicle
battery.
