The recommended gear display is intended as
a guideline only; it shou
ld never replace the
driver's attention to driving carefully.
● Responsibility for selecting the correct gear
for eac

driver, for example when overtaking, climb-
ing a hill or towing a trailer. For the sake of the environment

Intr oduction The power steering is not hydraulic but elec-
tr
omec
h
anical. The advantage of this steer-
ing system is that it disposes of hydraulic
tubes, hydraulic oil, the pump, filter and oth-
er components. The electromechanical sys-
tem saves fuel. While a hydraulic system re-
quires oil pressure to be maintained, electro- mechanical steering only requires energy
when the steerin
g wheel is turned.
With the power steering system, the assisted
steering function automatically adjusts ac-
cording to the vehicle speed, the steering tor-
que and the wheel turning angle. The power
steering only works when the engine is run-
ning. WARNING
If the power steering is not working then the
st eerin
g wheel is much more difficult to turn
and the vehicle more difficult to control.
● The power steering only works when the
engine is
running.
● Never allow the vehicle to move when the
engine is
switched off.
● Never remove the key from the ignition if
the vehic
le is in motion. The steering may
lock and it will not be possible to turn the
steering wheel. Control and warning lamps

Therefore, the vehicle should be at a stand-

in position P.
If the driver door is opened before the igni-

You should remember that you will need con-

the vehicle if the power steering is not work-

Counter steering assistance system
The counter steering assistance system helps
the driver in critical situations. Additional
steering power helps the driver when counter
steering. WARNING
The counter steering assistance system com-
bined w ith E
SC helps the driver to steer the
vehicle in critical driving conditions. At all
times, it is the driver who steers the vehicle.
The counter steering system does not steer
the vehicle. Run-in and economical driving
Ru nnin
g in Please observe the instructions for running-in

omponents.
R u
nning-in the engine
The engine needs to be run-in over the first
1500 km (1000 miles). During its first few
hours of running, the internal friction in the
engine is greater than later on when all the
moving parts have bedded down.
How the vehicle is driven for the first
1500 km (1000 miles) influences the future
engine performance. Throughout the life of
the vehicle, it should be driven at a moderate
speed – especially when the engine is cold –
this will reduce engine wear and increase its
useful life. Never drive at extremely low en-
gine speeds. Always engage a lower gear
when the engine works “irregularly”. For the
first 1000 km or 600 miles, please note: »

eep it pressed down. The en-
gine switches off.
● The engine will start again as soon as you
rele
ase the brake pedal.
● With the selector lever set to position P, the

Fuel tank not closed
correctly.Stop the vehicle and close the
tank flap properly.
Several warning and control lamps light up
f
or a f
ew sec
onds when the ignition is switch-
ed on, signalling that the function is being
verified. They will switch off after a few sec-
onds. When the or contro
l lamp lights up, the
auxiliary heater running and the supplemen-
tary heater automatically switch off. WARNING
Driving with insufficient fuel reserve could re-
su lt
in the vehicle breaking down in traffic
and a serious accident.
● If the fuel level is too low then the fuel sup-
ply t
o the engine can become irregular espe-
cially on slopes.
● If the engine “is choked” or stalls due to
lack
of or irregularity of the fuel supply, the
power steering as well as all of the driver as-
sistance systems including braking assis-
tance will stop working.
● Always refuel when there is only one quar-
ter of the f
uel tank left to avoid running out of
fuel. CAUTION
● Alw a
ys pay attention to any lit control
lamps and to the corresponding descriptions
and instructions to avoid damage to the vehi-
cle.
● Never run the fuel tank completely dry. An
irregu
lar fuel supply may lead to ignition
faults and unburnt fuel could enter the ex-
haust system. This could damage the catalyt-
ic converter filter or the diesel particulate fil-
ter! Note
