● The le g
al requirements regarding the use of
vehicle lights in each country must be ob-
served.
● The dipped beam headlights will only work
with the ignition on. The s
ide 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 can dazzle drivers behind
you. Y
ou should use the rear fog light only
when visibility is very poor. For this reason, if
you exceed approximately 60 km/h (38 mph),
the instrument panel will display the follow-
ing warming: Switch off the fog light!
● The use of the lighting described here is
subj
ect 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
● Ev en if
the automatic 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 v
ehicles with the automatic headlight
system, when the key is removed from the ig-
nition, the audible warning will only sound if
the light knob is in position .
● The use of the lighting described here is
subj
ect to the relevant statutory require-
ments. ●
Do not p ut
stickers on the windscreen in
front of the sensor. This may cause disrup-
tions or faults in the automatic lighting sys-
tem.
● The rain sensor switches on the dipped

● Always note the corresponding warnings
›››
page 69. WARNING
The rain sensor* may not detect enough rain
t o sw it
ch on the wipers.
● If necessary, switch on the wipers manually
when water on the w
indscreen obstructs visi-
bility. CAUTION
In icy conditions, always check that the wind-
sc r
een wipers and the window wiper are not
frozen. If you switch on the windscreen wip-
ers when the wiper blades are frozen to the
windscreen, you could damage both the wip-
er blades and the wiper motor. Note
● The wiper s
and washers will work only
when the ignition is switched on.
● The heat output of the heated jets* is con-
trol
led automatically when the ignition is
switched on, depending upon the outside
temperature.
● In certain versions of vehicles with alarms,
the winds
creen wiper will only work in inter-
val/rain sensor mode when the ignition is on
and the bonnet closed. ●
When the inter v
al wipe function is on, the
intervals are directly proportional to the
speed. This way, the higher the vehicle speed
the shorter the intervals.
● If you stop the vehicle with the windscreen
wiper in pos
ition 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
appro
ximately 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.
● Depending on the version of the model,
when you en
gage reverse gear and with the
headlight wiper activated, this can start a
wipe. Rear view mirrors

le
arly through the rear window. Interior mirror with automatic anti-dazzle
function*
The anti-d
azzle function is activated every
time the ignition is switched on.
When the anti-dazzle function is enabled, the
interior rear vision mirror will darken auto-
matically according to the amount of light it
receives. The anti-dazzle function is cancel-
led if reverse gear is engaged. Note
● The autom atic
anti-dazzle function will only
work properly if the sun blind* for the rear
window is retracted and there are no other
objects preventing light from reaching the in-
terior rear vision mirror.
● If you have to stick any type of sticker on
the winds
creen, do not do so in front of the

Introduction The power steering is not hydraulic but elec-
tromec
h
anical. 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 mor e s
trength to turn the wheel.
This has a considerable effect on vehicle
safety.
● 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
while the
vehicle is moving. The steering lock could be engaged and vehicle steering would
not w
ork. Note
The ignition of the vehicle being towed must
be sw itc
hed on to 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 is switched on. It
should go out once the engine is started.

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.

If necessary, check the messag-
es 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 assistance. WARNING
If the warning lamps and the corresponding
mes s
ages are ignored when they light up, the
vehicle may stall in traffic and cause acci-
dents and severe injuries.
● Never ignore the warning lamps or messag-
es.
● Stop the
vehicle at the next opportunity

Advice
●
Never c o
ver the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pans
ion tank when the engine is hot. If the
coolant is hot, the cooling system will be
pressurised!
● Protect face, hands and arms by covering
the cap with a l
arge, thick cloth to protect
against escaping coolant and steam.
● Always make sure you have not left any ob-
jects, s
uch as cleaning cloths or tools, in the
engine compartment.
● If you have to work underneath the vehicle,
you mus
t use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!. A hydraulic jack is insufficient for se-
curing the vehicle and there is a risk of injury.
● If any work has to be performed when the
engine is
started or with the engine running,
there is an additional, potentially fatal, safety
risk from the rotating parts, such as the drive
belts, alternator, radiator fan, etc., and from
the high-voltage ignition system. You should
also observe the following:
– Never touch the electrical wiring of the
ignition system.
– Ensure that jewellery, loose clothing and
long hair do not get trapped in rotating
engine parts. Danger of death. Before
starting any work remove jewellery, tie
back and cover hair, and wear tight-fit-
ting clothes. –
Never ac c
elerate with a gear engaged
without taking the necessary precau-
tions. The vehicle could move, even if the
handbrake is applied. Danger of death.
● If work has to be carried out on the fuel
syst
em or on electrical components, you
must observe the following safety notes in
addition to the above warnings:
– Always disconnect the battery from the
on-board network. The vehicle must be
unlocked when this is done, otherwise
the alarm will be triggered.
– Do not smoke.
– Never work near naked flames.
– Always have a fire extinguisher on hand. WARNING
If the bonnet is not correctly closed, it could
sud den
ly open while driving leaving the driv-
er without visibility. This could result in a se-
rious accident.
● After closing the bonnet, always check that
it is
properly secured by the locking mecha-
nism in the lock carrier piece. The bonnet
must be flush with the surrounding body pan-
els.
● While driving, if you notice that the bonnet
is not
correctly closed then stop immediately
and close it correctly.
● Only open and close the bonnet when there
is no
body within its range. CAUTION
When topping up service fluids, make sure
not t o mi
stake 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 this 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
