The legal requirements regarding the use of
vehicle lights in each country must be ob-
served.
The driver is personally responsible for the
correct use and adjustment of the lights in all
situations. WARNING
Never drive with just the side lights on, there
is a ri sk
of accident. The side lights are not
bright enough to illuminate the road ahead
and to ensure that other road users are able
to see you. Always use your dipped beam
headlights if it is dark or if visibility is poor. Note
● The dipped beam he a
dlights will only work
with the ignition on. The side lights come on
automatically when the ignition is turned off.
● If the lights are left on after the key has
been taken out of
the ignition lock, an audi-
ble warning sounds while the driver door re-
mains open. This is a reminder to switch the
lights off.
● The rear fog light is so bright that it can
dazzle driv
ers behind you. You should use
the rear fog light only when visibility is very
poor. ●
The use of the lightin g de
scribed here is
subject to the relevant statutory require-
ments. Automatic lighting*

If automatic headlight control is switched on,
dipped beam headlights are automatically
switched on by a photosensor if you drive in-
to a tunnel, for example. WARNING
● Even if the aut
omatic headlight control is
switched on, the dipped beam headlights will
not be switched on with fog. Therefore, the
dipped beam must be switched on manually. Note
● For those v
ehicles with the automatic head-
light system, when the key is removed from
the ignition, the audible warning will only
sound if the light knob is in position or . ●
If the da ylight
driving automatic light func-
tion is switched on, the front fog lights or
rear fog light cannot be switched on in addi-
tion.
● The use of the lighting described here is
subject
to the relevant statutory require-
ments.
● Do not put stickers on the windscreen in
front of the sen
sor. This may cause disrup-
tions or faults in the automatic lighting sys-
tem.
● The rain sensor switches on the dipped
beam headlight

have been operating continuously for a few
seconds and it switches the lights off when
the continuous or interval wipe is switched
off for some minutes. Daytime running lights
››› t
able on page 2
The daytime running lights are enabled auto-
matically when the ignition is switched on.
Daytime running lights are signalling devices
for improving road safety. The lights are built
into the headlights and come on each time
the ignition is turned on if the light switch is
in position 0 or . It is automatically

● Worn and dirty w

ty and safety levels while driving.
● In cold conditions you should not use the
wash/wipe sy
stem unless you have warmed
the windscreen with the heating and ventila-
tion system. The windscreen washer fluid
could otherwise freeze on the windscreen and
obscure your view of the road.
● Always note the corresponding warnings
››› p
age 54. WARNING
The rain sensor* may not detect enough rain
to swit c
h on the wipers.
● If necessary, switch on the wipers manually
when water on the wind
screen obstructs visi-
bility. CAUTION
In icy conditions, always check that the wiper
bla de
s are not frozen to the glass before us-
ing the wipers for the first time. If you switch
on the windscreen wipers when the wiper
blades are frozen to the windscreen, you
could damage both the wiper blades and the
wiper motor. Note
● The winds c
reen wipers will only work when
the ignition is switched on.
● The heat output of the heated jets* is con-
troll
ed automatically when the ignition is
switched on, depending upon the outside
temperature.
● In certain versions of vehicles with alarms,
the windsc
reen wiper will only work in inter-
val/rain sensor mode when the ignition is on
and the bonnet closed.
● When the interval wipe function is on, the
interva
ls are directly proportional to the
speed. This way, the higher the vehicle speed
the shorter the intervals. ●
If y ou s
top the vehicle with the windscreen
wiper in position 1 or 2, it will automatically
change to a lower position speed. The set
speed will be resumed when the vehicle pulls
away.
● The windscreen will be wiped again after
approx
imately five seconds once the “auto-
matic wash/wipe system” has been activa-
ted, provided the vehicle is moving (drip func-
tion). If you activate the wipers less than 3
seconds after the drip function, a new wash
sequence will begin without performing the
last wipe. For the “drip” function to work
again, you have to turn the ignition off and
then on again.
● Do not put stickers on the windscreen in
front of the
rain sensor*. This may cause sen-
sor disruption or faults. Rear window wiper

blade and the wiper motor. Note
● The rear w indo

used and the window wiper lever is pulled to-
wards the steering wheel for at least 1.5 sec-
onds – provided the dipped beam headlights
or main beams are switched on. Clean off
stubborn dirt (insects, etc.) from the head-
lights at regular intervals, for instance when
filling the fuel tank. Note
● To ens ur
e that the headlight washers work
properly in winter, keep the nozzle holders in
the bumper free of snow and remove any ice
with a de-icer spray.
● To remove water, the windscreen wipers

Introduction The power steering is not hydraulic but elec-
tromech
anic
al. The advantage of this steer-
ing is that it foes not need flexible hydraulic
pipes, hydraulic oil, pump, filter or other
parts. The electromechanical system saves
fuel. Whereas a hydraulic system needs con-
tinuous oil pressure, electromechanical
steering only needs power when it is used.
In vehicles with electromechanical steering,
the assisted steering function automatically
adjusts according to vehicle speed, steering
wheel torque and wheel orientation. The
power steering only works when the engine
is running. WARNING
If the power steering does not work, you will
need much more s tr
ength to turn the wheel.
This has a considerable effect on vehicle
safety.
● The power steering only works when the
engine is ru
nning.
● Never allow the vehicle to move when the
engine is sw
itched off.
● Never remove the key from the ignition
while the v
ehicle is moving. The steering lock could be engaged and vehicle steering would
not work.
Note
The ignition of the vehicle being towed must
be sw itched on t
o prevent the steering wheel
from locking and also to allow the use of the
turn signals, horn, windscreen wipers and
washers. Control lamp
The control lamp should light up for a few
sec
ond
s when the ignition i
s switched on. It
should go out once the engine is started.
It lights up red
The electromechani-
cal steering is dam-
aged.Have the steering checked im-
mediately by a specialised work-
shop.
It lights up yellow
Electromechanical
steering operation
is limited.See a specialised workshop im-
mediately and have the steering
checked.
If the yellow warning lamp does
not light up again after the en-
gine is restarted and the vehicle
has travelled a short distance,
you do not need to take it to a
specialised workshop. 148

Checking and refilling levels
●
Only open and c lo
se the bonnet when there
is nobody within its range. CAUTION
When topping up service fluids, make sure
not to mi s
take them. Using the wrong fluids
could cause serious malfunctions and engine
damage! For the sake of the environment
Service fluids leaks are harmful to the envi-
ronment. F or thi
s reason you should make
regular checks on the ground underneath
your vehicle. If you find spots of oil or other
fluids, have your vehicle inspected in a speci-
alised workshop. Opening the bonnet

The bonnet is released from inside the vehi-
cle.
Before opening the bonnet ensure that the
windscreen wipers are in rest position. WARNING
Hot coolant can scald! ●
Never open the bonnet if
you see steam,
smoke or coolant escaping from the engine
compartment.
● Wait until no more steam, smoke or coolant
is emitted fr
om the bonnet, then carefully
open the bonnet.
● When working in the engine compartment,
alway
s observe the safety warnings
››› page 201. Closing the bonnet
–
Slightly lift the bonnet.
– Release the bonnet stay and replace it in its
sup
por t
.
– At a height of approximately 30 cm let it fall
so it locks.
If
the bonnet does not close, do not press
downwards. Open it again and let it fall as
mentioned above. WARNING
If the bonnet is not closed properly, it could
open while y
ou are driving and completely
obscure your view of the road. Risk of acci-
dent.
● After closing the bonnet, always check that
it is pr
operly secured. The bonnet must be
flush with the surrounding body panels. ●
If y ou notic
e that the bonnet latch is not se-
cured when the vehicle is moving, stop the
vehicle immediately and close the bonnet
properly. Risk of accident. 203
