Driving and operating209
■ There are adverse environmentalconditions, e.g. heavy rain, snow,
direct sunlight or shadows. In this
case No Traffic Sign Detection due
to Weather is indicated on the
display.
■ Traffic signs are incorrectly mounted or damaged.
■ Traffic signs do not comply with the
Vienna Convention on traffic signs
(Wiener Übereinkommen über
Straßenverkehrszeichen).Caution
The system is intended to help the driver within a defined speed
range to discern certain traffic
signs. Do not ignore traffic signs
which are not displayed by the
system.
The system does not discern any other than the conventional traffic
signs that might give or end a
speed limit.
Do not let this special feature
tempt you into taking risks when
driving.
Always adapt speed to the road
conditions.
The driver assistance systems do not relieve the driver from full
responsibility for vehicle
operation.
Lane departure warning
The lane departure warning systemobserves the lane markings between
which the vehicle is driving via a front camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
via visual and acoustic signals.
Criteria for the detection of an
unintended lane change are:
■ No operation of turn signals.
■ No brake pedal operation.
■ No active accelerator operation or speeding-up.
■ No active steering.
If the driver is active, no warning will
be issued.
Activation
The lane departure warning system is activated by pressing ). The
illuminated LED in the button
indicates that the system is switched
on. When control indicator ) in the
instrument cluster illuminates green, the system is ready to operate.
The system is only operable at
vehicle speeds above 35 mph and if
lane markings are available.

218Driving and operatingTrailer towingTrailer 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
3 287.
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 (75 kg) 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.Rear axle load
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) may be exceeded by
60 kg , the gross vehicle weight rating
may be exceeded by 60 kg. If the
permissible rear axle load is
exceeded, a maximum speed of
60 mph applies.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.

226Vehicle care
Pull out the dipstick, wipe it clean,insert it to the stop on the handle, pull
out and read the engine oil level.Caution
It is the owner's responsibility to
maintain the proper level of an
appropriate quality oil in the
engine.
Insert dipstick to the stop on the
handle and make half a turn.
Different dipsticks are used
depending on engine variant.
When the engine oil level has
dropped to the MIN mark, top up
engine oil.
We recommend the use of the same
grade of engine oil that was used at
last change.
The engine oil level must not exceed
the MAX mark on the dipstick.Caution
Overfilled engine oil must be
drained or suctioned out.
Capacities 3 304.
Fit the cap on straight and tighten it.
Engine coolant The coolant provides freeze
protection down to approx. -28 °C. In
northern countries with very low
temperatures, the factory filled
coolant provides frost protection
down to approx. -37°C.
Caution
Only use approved antifreeze.
