two po s

itions for opening windows and two
for closing them. This makes it easier to open
and close windows to the desired position.
One-touch closing
– Pull up the window button briefly up to the
second po s

ition. The window closes fully.
One-touch opening
– Push down the window button briefly up to
the second pos

ition. The window opens
fully.
Resetting one-touch opening and closing
The automatic open and close function will
not work if the battery has been temporarily
disconnected. The function can be restored
as follows:
– Close the window as far as it will go by lift-
ing and hol

ding the electric window switch. –
Rele
ase the switch and then lift it again for
1 second. This will re-enable the automatic
function.
If you push (or pull) a button to the first
stage, the window will open (or close) until
you release the button. If you push or lift the
button briefly to the second stage, the win-
dow will open (one-touch opening) or close
(one-touch closing) automatically. If you op-
erate the button while the window is opening
or closing, it stops at this position.

Lights and visibility
WARNING
● Never driv e w
ith daytime lights if the road
is not well lit due to weather or lighting con-
ditions. Daytime lights do not provide
enough light to illuminate the road properly
or be seen by other road users.
● The rear lights do not come on with the
daytime driv
ing light. A vehicle which does
not have the rear lights on may not be visible
to other drivers in the darkness, in the case
of heavy rain or in conditions of poor visibili-

function can be deactivated in
a specialised workshop. WARNING
Improper or lack of use of the turn signals, or
for g

etting to deactivate them can confuse
other road users. This could result in a seri-
ous accident.
● Always give warning when you are going to
chan
ge lane, overtake or when turning, acti-
vating the turn signal in good time.
● As soon as you have finished changing
lane, ov
ertaking or turning, switch the turn
signal off. WARNING
Incorrect use of the headlights may cause ac-
cident s

and serious injury, as the main beam
may distract or dazzle other drivers. Note
● If the c on

venience turn signals are operat-
ing (three flashes) and the other convenience
turn signals are switched on, the active part
stops flashing and only flashes once in the
new part selected.
● The turn signal only works when the igni-
tion is sw
itched on. The hazard warning
lights also work when the ignition is switch-
ed off. ●
If a tr ai

ler turn signal malfunctions, the
control lamp will stop flashing (trailer turn
signals) and the vehicle turn signal will flash
at double speed.
● The main beam headligh
ts can only be
switched on if the dipped beam headlights
are already on.
● In cold or damp weather conditions, the
headlight

● In poorly lit towns with highly reflective
signs.
● Other in

sufficiently lit road users (such as
pedestri

On tight bends
and steep slopes (bumps)
and when oncoming vehicles are partially ob-

rail in the centre of the road.
● If the camera is damaged or the power sup-
ply i

● In fog, snow and heavy rain.
● With dust and sand turbulence.
● With loose gravel in the field of vision of
the camera.
● When the fiel

ice, etc. WARNING
The convenience features of the main beam

ist should not encourage the taking of
risks. The system is not a replacement for
driver concentration.
● You are always in control of the main beam
and adaptin
g it to the light, visibility and traf-
fic conditions.
● It is possible that the main beam headlight
contro

The hazard warning lights are used to draw
the attention of other road users to your vehi-
cle in emergencies.
If your vehicle breaks down:
1. Park your vehicle at a safe distance from movin
g traffic.
2. Press the button to switch on the hazard warning lights
››› .
3. Switch the ignition off.
4. Apply the handbrake.
5. For a manual gearbox, engage 1st gear; for an aut
om

atic gearbox, move the gear
lever to P. 6. Use the warning triangle to draw the atten-
tion of other ro
ad users to your vehicle.
7. Always take the vehicle key with you when you le
ave the vehicle.
All turn signals flash simultaneously when
the hazard warning lights are switched on.
The two turn signal turn signal lamps  
and the turn signal lamp in the switch  will
flash at the same time. The simultaneous
hazard warning lights also work when the ig-
nition is switched off.
Emergency braking warning
If the vehicle brakes suddenly and continu-
ously at a speed of more than 80 km/h (50
mph), the brake light flashes several times
per second to warn the vehicles driving be-
hind. If you continue braking, the hazard
warning lights will come on automatically
when the vehicle comes to a standstill. They
switch off automatically when the vehicle
starts to move again. WARNING
● The risk of

an accident increases if your ve-
hicle breaks down. Always use the hazard
warning lights and a warning triangle to draw
the attention of other road users to your sta-
tionary vehicle.
● Due to the high temperatures that the cata-
lytic con
verter can reach, never park in an
area where the catalytic converter could come into contact with highly inflammable materi-
al
s, f

or example dry grass or spilt petrol. This
could start a fire. Note
● The b atter

y will run down if the hazard
warning lights are left on for a long time,
even if the ignition is switched off.
● The use of the hazard warning lights de-
scribed her
e is subject to the relevant statu-
tory requirements. Parking lights
 When the parking light is switched on, (right

the rear light on the corresponding side of
the vehicle stay lit. The parking lights can on-

Headlight wash/wipe system
The headlight washers/wipers clean the
headlight lenses.
After the ignition is switched on, the first and
every fifth time the windscreen washer is
switched on, the headlights are also washed.
Therefore, the windscreen wiper lever should
be pulled towards the steering wheel when
the dipped beam or main beam are on. Any
incrusted dirt (such as insects) should be
cleaned regularly (e.g. when refuelling).
To ensure the headlight washers work cor-
rectly in winter, any snow which has got into
the bumper jet supports should be cleaned
away. If necessary, remove snow with an anti-
icing spray. Note
The wiper will try to wipe away any obstacles
that ar

e on the windscreen. The wiper will
stop moving if the obstacle blocks its path.
Remove the obstacle and switch the wiper
back on again. 149
