Main beam headlights
This control lamp lights up when the main beams are on.
The warning lamp is switched on once main beams are on or once the
headlight flasher is operating.
For further information see ⇒ page 106.
Electro-hydraulic steering*
The level of steering assistance depends on the vehicle speed and on the
steering wheel turning speed.
The control lamp should light up for a few seconds when the ignition is
switched on. It should go out once the engine is started.
There is a fault in the electro-hydraulic steering system if the lamp does not
go out or lights up whilst the vehicle is in motion. Take the vehicle to the
Technical Service as soon as possible.
Note
When towing the vehicle with the engine stopped or due to a fault in the
power steering, this will not operate. The vehicle can still be steered, but it
will require greater force to turn the steering wheel. Emission control system*
This warning lamp monitors the exhaust system.
Control lamp flashes:
When there is misfiring that can damage the catalytic converter. Reduce
speed and drive carefully to the nearest specialised workshop to have the
engine checked.
Control lamp is lit:
If a fault has developed during driving which has reduced the quality of the
exhaust gas (e.g. lambda probe fault). Reduce speed and drive carefully to
the nearest specialised workshop to have the engine checked.
Coolant level*/temperature
The warning lamp lights up if the coolant temperature is too
high or if the coolant level is too low.
There is a fault if:
● The warning symbol does not go out again after a few seconds.
● The warning lamp lights up or flashes while the vehicle is moving, and
three acoustic warning signals ⇒
are emitted.
This means that either the coolant level is too low or the coolant tempera-
ture is too high.
Coolant temperature too high
If the warning light comes on, stop the vehicle, switch off the engine and
wait for it to cool down. Check the coolant level.
If the coolant level is correct, the overheating may be caused by a malfunc-
tion of the radiator fan. Check the radiator fan fuse and have it replaced if
necessary ⇒ page 231.

Instrument and switch lighting / Headlight range control
Fig. 56 Dash panel: reg-
ulation for instrument
and switch lighting and
headlight range control
Instrument and switch lighting 1
When the headlights are switched on, the brightness of the instruments
and switch lighting can be regulated to suit your requirements by turning
the thumb wheel
⇒ Fig. 56 1
.
Vehicles fitted with xenon gas discharge headlights are fitted with an auto-
matic headlight range system.
The instrument lighting (some dials and needles), the centre console light-
ing and the lighting of the displays are regulated by a photodiode incorpo-
rated in the instrument panel.
The instrument lighting (needles) is switched on when the ignition is on and
the light is off . The instrument lighting is dimmed automatically as the day-
light starts to fade. It goes out completely when the ambient light level is
very low. This function is intended to remind the driver to switch on the dip-
ped beam headlights in good time when light conditions become poor. Headlight range control
2
By using the electrical headlight range control, 2 you can adjust the head-
light range to the load level that is being carried in the vehicle. This way, it
is possible to avoid dazzling oncoming traffic more than necessary. 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.
To lower the beam, turn the thumb wheel down 2
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 regu-
lates itself according to the vehicle load.
Vehicles with gas discharge bulbs do not have headlight range control.
Daytime driving lights*
Daytime driving lights light up automatically when the igni-
tion is switched on (only with AFS headlights)
Daylight driving lights switch off automatically when the side lights are
switched on.
Activating daytime lights (bi-xenon lamps)
Remove the key from the ignition, move the turn signal lever upwards (right
turn signal), press it backwards to flash position and hold in this position.
Insert the key and switch the ignition on, holding it in this position for 3
seconds. Then, switch off the ignition. The daytime lights are activated and
can be switched on.
Switching daytime lights off (bi-xenon lamps)
Remove the key from the ignition, move the turn signal lever upwards (left
turn signal), press it backwards to flash position and hold in this position.

Note
● The battery 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 described here is subject to the rel-
evant statutory requirements.
Turn signal and main beam headlight lever
The turn signal and main beam lever also operates the park-
ing lights and the headlight flasher.
Fig. 60 Turn signal and
main beam headlight lev-
er
The turn signal and main beam headlight lever has the following
functions:
Switching on the turn signals
– Move the lever all the way up ⇒
Fig. 60 1
to indicate right, and
all the way down 2 to indicate left. Signalling a lane change
–
Push the lever up 1
or down 2 to the point where you incur
resistance and then release it. The turn signal will flash several
times. The corresponding control lamp will also flash.
Switching main beam on and off
– Turn the light switch to position .
– Press the lever forward ⇒ Fig. 60 4
to switch on the main
beams.
– Pull the lever back towards you to switch the main beam head-
lights off again.
Headlight flashers
– Pull the lever towards the steering wheel 3
to operate the
flasher.
Switching on parking lights
– Switch the ignition off and remove the key from the lock.
– Move the turn signal lever up or down to turn the right or left-
hand parking lights on, respectively.
WARNING
The main beam can dazzle other drivers. Risk of accident! Never use the
main beam headlights or the headlight flasher if they could dazzle other
drivers.

Lights and visibility
Note
● The turn signals only work when the ignition is switched on. The corre-
sponding warning lamp or flashes in the instrument panel. The control
lamp flashes when the turn signals are operated, provided a trailer is
correctly attached and connected to the vehicle. If a turn signal bulb is de-
fective, the control lamp flashes at double speed. If the trailer turn signal
bulbs are damaged, control lamp does not light up. Change the bulb.
● The main beam headlights can only be switched on if the dipped beam
headlights are already on. The warning lamp then comes on in the instru-
ment panel.
● The headlight flasher comes on for as long as you pull the lever – even if
no other lights are switched on. The warning lamp then comes on in the
instrument panel.
● When the parking lights are switched on, the headlight and the tail light
on the corresponding side of the vehicle light up. The parking lights will on-
ly work if the key is removed from the ignition. If the lights are switched on,
an audible warning will be emitted while the driver door is open.
● If the turn signal lever is left on after the key has been taken out of the
ignition lock, an acoustic signal sounds when the driver door is opened.
This is a reminder to switch off the turn signal, unless of course you wish to
leave the parking light on. Interior lights

Setting a higher speed
– Press the upper part RES of the rocker switch ⇒ Fig. 122 B
