This cornering light gives better illumination
of the side of the road and the corner area.
The dynamic lighting is controlled automati-
cally according to speed and the steering
wheel angle. The two main headlights move at different
angles
to avoid that the front of the vehicle is
left completely in the dark. Note
The system operates from a speed of about
10 km/h (6 mph). Fog lights with cornering function*

The cornering light operates with the lights
switched on and when driving at less than
40 Km/h (25 mph). Ignition occurs by turning
the steering or connecting the turn signal.

Lights and visibility
The instrument lighting (needles) is switched
on when the ignition i s
on and the light i
s
off. The instrument lighting is dimmed auto-
matically as the daylight starts to fade. It
goes out completely when ambient light is
very low. This function is intended to remind
the driver to switch on the dipped beam
headlights in good time when light condi-
tions become poor.
Headlight range control
By using the electrical headlight range con-
trol you can adjust the headlight range to the
load level that is being carried in the vehicle
››› Fig. 135. This way, it is possible to avoid
dazzling oncoming traffic more than necessa-
ry. At the same time, by using the correct
headlight settings, the driver has the best
possible lighting for the road ahead.
The headlights can only be adjusted when
the dipped beam is switched on. Turn the
wheel downwards to lower the headlight
beam from the basic setting 0.
Dynamic headlight range control
Vehicles with gas discharge bulbs (xenon
bulbs) are equipped with dynamic headlight
range control. When you switch on the lights,
their range regulates itself according to the
vehicle load.
Vehicles with gas discharge bulbs do not
have headlight range control. Hazard warning lights

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 moving tr
affic.
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
omatic
gearbox, move the gear
lever to P.
6. Use the warning triangle to draw the atten- tion of other roa
d users to your vehicle.
7. Always take the vehicle key with you when you leav
e 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. WARNING
● The risk of an ac
cident 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 conv
erter can reach, never park in an
area where the catalytic converter could come
into contact with highly inflammable materi-
als, for example dry grass or spilt petrol. This
could start a fire. Note

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.

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

ignition has been switched on.
Seek specialist assistance. WARNING
If the warning lamps and the corresponding
mess ag
es 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 v
ehicle at the next opportunity
and in a safe pl
ace. Note
Failure to heed the control lamps and corre-
sponding t e
xt messages when they light up
may result in damage to the vehicle. Information relating to different vehi-
cle pr
oc
esses. In order to make the vehicle more difficult to
ste
al,
you should always lock the steering be-
fore leaving the vehicle.
Mechanical steering lock
The steering column is locked when the key
is removed from the ignition lock and the ve-
hicle is stationary.
Activating the steering lock
● Park the vehicle ›››
p
age 152.
● Remove the ignition key.
● Turn the steering wheel slightly until the
steering loc
k has engaged.
Deactivating the steering lock
● Turn the steering wheel slightly to release
the lock.
● Insert
the key in the ignition lock.
● Hold the steering wheel in this position
and switch on the ignition. El
ectromechanical steering
In vehicl
es 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.
You should take into account that you will
need considerably more power than normal
to steer the vehicle if the power steering is
not working correctly or at all.
Power-assisted steering
Power-assisted steering helps the driver in
critical situations. In counter-steering, it as-
sists by applying additional torque ››› .
WARNING
Power-assisted steering, together with the
ESC, helps the driv
er to control vehicle steer-
ing in critical situations. However, the driver
is ultimately responsible for steering the ve-
hicle at all times. Power-assisted steering
does not remove this responsibility. 149

of your brake pads checked by technical serv-
ic e
s mor
e frequently than recommended in
the Maintenance Programme.
If you drive with wet brakes, for example, af-
ter crossing areas of water, on days of heavy
rainfall or even after washing the car, the ef-
fect of the brakes is reduced as the brake
discs are wet or even frozen (in winter): in
this case, the brakes should be “dried” by
pressing the brake pedal several times. WARNING
Longer braking distances and faults in the
brake sy s
tem increase the risk of accidents.
● New brake pads must be run in and do not
have the corr
ect friction during the first
200 km. This reduced braking capacity may
be compensated for by pressing on the brake
pedal a little harder, which also applies when
the brake pads have to be changed further
on.
● If brakes are wet or frozen, or if you are
driving on ro
ads which have been salted,
braking power may be lower than normal.
● On steep slopes, if brakes are excessively
used, they wi
ll overheat. Before driving down
a long steep slope, it is advisable to reduce
speed and change down into a lower gear or
range (depending on the type of transmis-
sion). Thus, make use of engine braking and
relieve the brakes.
● Never let the brakes “drag” by applying
light pres
sure. Continuous braking will cause the brakes to overheat and the braking dis-
tance w
i
ll increase. Apply and then release
the brakes alternately.
● Never let the vehicle run with the engine
switched off
. The braking distance is in-
creased considerably when the brake servo is
not active.
● If the brake fluid loses its viscosity and is
subject
ed to heavy use, vapour bubbles can
form in the brake system. This reduces the ef-
ficiency of the brakes.
● Non-standard or damaged front spoilers
could r
estrict the airflow to the brakes and
cause them to overheat. Before purchasing
accessories please observe the relevant in-
structions ››› page 190, Modifications.
● If a brake system circuit fails, the braking
distanc
e will be increased considerably. Con-
tact a specialised workshop immediately and
avoid unnecessary journeys. Control lamp

● If the brake warning lamp lights up to-
gether with the ABS

wheels to lock quickly when you brake. This
could cause the rear to break away. Risk of
skidding. Stop the vehicle and seek technical
assistance. Handbrake
