Driving and operating129Driving hints
Driving economically
ECO mode ECO mode is a function that
optimises fuel consumption. It affects
engine power and torque,
acceleration, gear shift indication,
heating, air conditioning and electrical consumers.
ActivationPress ECO. Control indicator
illuminates when activated and a corresponding message appears in
the Driver Information Centre 3 98.
During driving, it is possible to
temporarily disable ECO mode, e.g.
to increase engine performance, by
depressing the accelerator pedal
firmly.
ECO mode is reactivated when
pressure is reduced on the
accelerator pedal.
Deactivation
Press ECO again. Control indicator
extinguishes.
Control of the vehicle
Never coast with engine not
running (except during Autostop)
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. All
systems function during an Autostop,
but there will be a controlled reduction
in power steering assist and vehicle
speed is reduced.Stop-start system 3 132.
Pedals To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.
Use only floor mats which fit properly
and are fixed by the retainers on the
driver's side.
Steering
If power steering assist is lost
because the engine stops or due to a system malfunction, the vehicle can
be steered but may require increased
effort.Caution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
than 15 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.
Driving and operating133An Autostop is indicated when Ï
illuminates green in the instrument
cluster.
During an Autostop, the heating
performance, power steering and
brake performance will be
maintained. Brake assist, however, is
not available 3 151.
Note
If you exit the vehicle while the
engine is in an Autostop, a warning
chime will sound as a reminder that
the engine is on standby and has not been switched off.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled,
otherwise an Autostop will be
inhibited and control indicator \ will
illuminate in the instrument cluster.
● the stop-start system is not manually deactivated
● the bonnet is fully closed
● the driver's door is closed or the driver's seat belt is fastened
● the vehicle battery is sufficiently charged and in good condition● the engine is warmed up
● the engine coolant temperature is
not too high
● the ambient temperature is not too low
● the defrosting function is not activated
● the climate control system does not inhibit an Autostop
● the brake vacuum is sufficient ● the self-cleaning function of the diesel particle filter is not active
● the vehicle has moved since the last Autostop
Otherwise an Autostop will be
inhibited.
An Autostop may become
unavailable as the ambient
temperature approaches freezing
point.
Certain settings of the climate control system may also inhibit an Autostop.See "Climate control" chapter for
further information 3 112.
Immediately after motorway driving
an Autostop may be inhibited.Autostop may also be inhibited
temporarily if the vehicle battery has
been recharged by an external
source.
New vehicle running-in 3 130.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Restart of the engine by the driver
Depress the clutch pedal to restart the
engine.
If the selector lever has been shifted
out of neutral (manual transmission)
or N (manual transmission
automated) or other conditions are
not met, start using the ignition key.
The green control indicator Ï will
extinguish in the instrument cluster
when the engine is restarted.
If the selector lever is shifted out of
neutral (manual transmission) or N
(manual transmission automated) before depressing the clutch first, a
restart will not take place.
166Driving 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 80 km/h 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 3 239.
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
3 218.
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.
Driving and operating167In the case of trailer loads of
1200 kg or more, the vertical coupling
load should not be less than 50 kg.
Rear axle loadWhen 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.
Towing equipment audible
warning
For vehicles fitted with towing
equipment, 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
change if a turn signal light on the
trailer or the towing vehicle fails.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is
selectively 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 (ESP) 3 152.Auxiliary features
Power take-off
Activation
To activate the power take-off, with
the vehicle stationary and the engine
idling:
● Set the gearshift lever to neutral (vehicles with manual
transmission automated:
selector lever in position N).
● Depress the clutch pedal.
