Note
The recommended gear display is switched
off when the c lut
ch pedal is pressed.Steering
Introduction The power steering* is not hydraulic but elec-
tromec
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 steering 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 a l

low 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

Remove the key from the ignition and
then switch the ignition back on. If nec-
essary, check the messages displayed
on the instrument panel display.
Do not drive on, if
the steering column
remains locked after the ignition has
been switched on. Seek specialist assis-
tance. 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. WARNING
If the warning lamps are ignored, the vehicle
ma y

stall in traffic, or may cause accidents
and severe injuries.
● Never ignore the warning lamps.
● Stop the vehicle safely as soon as possible. CAUTION
Failure to heed the warning lamps when they
appe ar m

ay result in faults in the vehicle. 147

Checking and refilling levels
driving. Whenever the ignition is switched
on, the needl e c
h
anges first for a few sec-
onds to the petrol area in order to display the
current level of fuel. The needle then moves
to the natural gas area. After the engine is
started, the needle changes to the area corre-
sponding to the current operating mode.
Problem: if the vehicle is left parked for a
long time just after refuelling, the gas level
indicator does not accurately indicate the
same level shown after refuelling when the
vehicle is started up again. This is not due to
a leak in the system, but to a drop in pres-
sure in the gas tank for technical reasons af-
ter a cooling phase immediately after refuel-
ling. 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. Note

Before refuelling, always turn off the engine,
the ignition, mobile telephones, auxiliary
heating and keep them off during refuelling.
Refuelling
The correct petrol type for the vehicle is loca-
ted on a sticker inside the fuel tank flap
››› page 181.
● If the automatic filler nozzle is operated
correctly
, it will switch itself off as soon as
the fuel tank is full ››› .
● Do not continue to refuel if it is turned off!
Other w
i

se, this will fill the expansion cham-
ber and fuel may leak out if the ambient con-
ditions are warm.
Vehicles with a natural gas engine
Every 6 months it is necessary to run on pet-
rol until the control lamp switches off  and
then the tank must be refilled. This is neces-
sary to ensure the efficient operation of the
system and the fuel quality required for run-
ning on gas. WARNING
Do not continue refilling once the fuel nozzle
ha s

switched itself off. The fuel tank may be
filled too much. As a result, fuel may spurt
out and spill. This could lead to a fire, explo-
sion and severe injuries. » 185

also essential to carefully read the in-
structions for the natural gas pump. The vehicle is equipped for refuelling only
with Compr

essed Natural Gas (CNG) ››› . Re-
f uel
lin
g with another type of natural gas is
not allowed, e.g. Liquefied Natural Gas (LNG)
or hydromethane.
Opening the fuel tank cap
The natural gas filler mouth is behind the fuel
tank cap, next to the petrol filler mouth.
● Unlock the vehicle with the key or with the
central
locking button  situated on the driv-
er door ››› page 97.
● Press on the rear area of the flap and open
it.
Ref

uelling
Problem: If the ambient temperature is very
high, the natural gas pump protection
against overheating disconnects this auto-
matically.
● Remove the plug from the gas filler mouth
›››
Fig. 167 1 .
● Connect the pump filling nozzle to the gas
fi l
l

er mouth.
● The fuel tank will be full when the p
ump
compressor automatically cuts the supply.
● If you wish to finish refuelling in advance,
pres
s the button on the pump to stop the
flow. Closing the fuel tank cap
●
Check that the gas filler mouth retainer 2 is not trapped with the filler nozzle. If neces-
s
ar
y

, place it in the filler mouth again.
● Insert the plug in the filler mouth.
● Close the tank flap. Make sure you hear it
click
into place. WARNING
Natural gas is a highly explosive, easily flam-
mab l

e substance. Incorrect handling of the
natural gas can cause accidents serious
burns and other injuries.
● Before refuelling with natural gas, the fill-
ing mouth mus
t be correctly engaged. If you
can smell gas, stop refuelling immediately. WARNING
The vehicle is not prepared to use liquefied
nat ur

al gas (LNG) and this fuel must not be
added under any circumstances. Liquefied
natural gas can cause the natural gas tank to
explode, resulting in serious injury. Note
● The fil lin

g nozzles of natural gas pumps
can differ in the way they are operated. If you
are unacquainted with the pump, it is advisa-
ble that a member of staff of the service sta-
tion performs the refuelling operation. 186
