Driving economically ECO mode
ECO mode is a function that
optimises fuel consumption. It affects engine power, heating, air
conditioning and electrical
consumers.
Activation
Press the ECO button. Control
indicator ECO illuminates in the
instrument cluster when activated.
During driving, it is possible to
temporarily disable ECO mode, e.g.
to increase engine performance, by
depressing the accelerator pedal
firmly. ECO flashes in the instrument
cluster.
ECO mode is reactivated when
pressure is reduced on the
accelerator pedal. ECO stops
flashing and illuminates continuously.
Deactivation
Press the ECO button again. Control
indicator ECO extinguishes in the
instrument cluster.
Control of the vehicle Never coast with engine not
running
Many systems will not function in this
situation ( e.g. brake servo unit, power
steering). Driving in this manner is a
danger to yourself and others.
Driving and operating129
The figures are provided only for the
purpose of comparison between different vehicle variants and mustnot 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.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 3 178.
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
130Driving and operating
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
3 169.
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.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.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced and the vehicle/trailer combination isselectively braked until the snaking
ceases. While the system is working,
keep steering wheel as still as
possible.
Trailer stability assist (TSA) is a
function of the Electronic Stability
Program 3 119.

162Vehicle care
To prevent the entry of exhaust fumesfrom the towing vehicle, switch on the
air recirculation system and close the windows.
Seek the assistance of a workshop.
After towing, unscrew the towing eye and replace cap.
Towing another vehicle
The fixed towing eye is located under the rear bumper.
Attach a tow rope - or better still a tow
rod - to the rear towing eye, never to
the rear axle and suspension units.
The rear towing eye must only be
used for towing and not recovering a
vehicle.Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.

Appearance care
Exterior care LocksThe locks are lubricated at the factory
using a high quality lock cylinder
grease. Use de-icing agent only when absolutely necessary, as this has a
degreasing effect and impairs lock
function. After using de-icing agent,
have the locks regreased by a
workshop.
Washing The paintwork of your vehicle is
exposed to environmental influences.
Wash and wax your vehicle regularly.
When using automatic vehicle
washes, select a programme that
includes waxing.
Bird droppings, dead insects, resin,
pollen and the like should be cleaned
off immediately, as they contain
aggressive constituents which can
cause paint damage.
