(AFL) ensures better illumination of
zbends (curve lighting),
z crossings and narrow bends (cornering
light).
Curve lighting
The light beam pivots based on
steering wheel position and speed (from
approx. 10 km/h).
The headlamps shine at an angle of up
to 15 to the right or left of the direction of
travel.
Picture no:
Cornering light
An additional lamp comes on with
certain steering wheel positions (after
approx. 90), turn si gnal settings and
speeds (up to approx. 40 km/h).
The light is thrown approx. 90 to the
left or right of the car, to a distance of
approx. 30 metres.
Reversing function
If the lights are on, reverse gear is
engaged, and the turn signal is activated,
the cornering light on the appropriate side
is switched on. The cornering light stays on
for 15 seconds once the turn signal has
been switched off.

about 4 seconds after the ignition is
switched on as a reminder that the
headlamps have been converted, see

The dipped headlamps come on for
around 30 seconds after switching on and
closing the driver’s door.
To activate:
1. Switch off ignition.
2. Remove ignition key.
3. Open driver’s door.
4. Pull turn signal stalk toward steering
wheel.
5. Close driver’s door. If the driver’s door is left open, the lamps
will go out after two minutes.
The light is switched off immediately by
inserting the key into
the ignition or pulling
the turn signal stalk towards the steering
wheel again.

Lead-me lighting when opening the
vehicle 3
The Lead-me-to-the-car lighting function
allows the dipped headlamps to be lit for
around 30 seconds using the remote
control.
This function must be activated (once):
Unlock the vehicle, put the key in the
ignition and press the light switch for
approx. 5 seconds - see next page,
Fig. 14136 S.
To deactivate the function permanently,
contact a workshop.

Some consumers such as the interior
lighting switch themselves off after
approx. 30 minutes if the ignition is off in
order to protect the battery charge. Misted light covers The inside of the light covers may mist up
briefly in poor, wet and cold weather
conditions, in heavy rain or after washing.
The mist disappears quickly by itself; to
help, switch on the lights. Headlamps when driving abroad The asymmetrical dipped beam increases
the field of vision on the passenger side of
the lane.
In countries where traffic drives on the
opposite side of the road, prevent glare as
follows.

1. Pull stalk towards steering wheel and hold.
2. Switch on ignition.
3. After approx. 3 seconds, an acoustic signal sounds and then AFL control
indicator
B flashes approx. 4 seconds.
After the switch, AFL control indicator
B
flashes for 4 seconds each time the ignition
is switched on. To return to asymmetrical dipped beam,
pull and hold the main beam stalk again,
switch on the ignition and wait for the
acoustic signal. AFL control indicator

148 Driving and operationCruise control 3
Cruise control can store and maintain
speeds of approx. 30 to 200 km/h.
Deviation from the stored speed is possible
on uphill or downhill inclines.
For safety reasons the cruise control
cannot be activated until the foot brake
has been operated once.
The cruise control is operated with the
buttons I, R and O on the turn signal lever.
Do not use the cruise control if it is not
advisable to maintain a constant speed
(e.g. in situations presenting a danger to
yourself and other road users, in heavy
traffic or on winding, slippery or greasy
roads). For manual transmission automated
3,
engage cruise control in automatic mode
only.

Control indicator
m 3
The warning lamp lights up for a few
seconds 3 when the ignition is switched on.
The system is now ready for operation.
When driving, th e warning lamp m lights
up as soon as the sy stem is switched on.
9 Warning
When the cruise control is active,
reaction times may be increased due to
the different position of the feet.

Driving and operation
Coupling socket load
The coupling socket load is the load
exerted by the trailer/caravan on the
coupling ball. It can be varied by changing
the weight distribution when loading the
trailer/caravan.
The maximum permissible coupling socket
load (55 kg) of the towing vehicle is
specified on the towing equipment
identification plate and in the vehicle
documents. This must always be complied
with, particularly in the case of heavy
caravans/trailers. The coupling socket load
should be no less than 25 kg.
When measuring the coupling socket load,
make sure that the drawbar of the loaded
trailer/caravan is at the same height as it
will be when the trailer/caravan is coupled
with the towing vehicle loaded. Particularly
important for trailers/caravans with
tandem axle. Rear axle load during towing
With the trailer connected and the towing
vehicle fully loaded including all
occupants, the permitted rear axle load
(specified on the identification plate and
vehicle documents) must be exceeded by
no more than 25 kg and the maximum
permitted gross vehicle weight by no more
than 30 kg. If the maximum permitted rear
axle load is exceeded, a maximum speed
of 100 km/h applies, and 80 km/h for
commercial vehicles.
Driving characteristics, towing tips
Before attaching th
e trailer/caravan,
lubricate the ball of the trailer/caravan
towing device. However, do not lubricate
the ball if a stabiliser, which acts on the
coupling ball, is being used to damp
hunting.
Check caravan/traile r lighting before
starting to drive. The fog tail lamps on the
vehicle are deactivated when towing a
caravan or trailer.
Trailers with LED turn signals must have a
provision enables lamp monitoring for
commercial bulbs.
Handling is greatly influenced by the
loading of the trailer/caravan. Loads
should therefore be secured so that they
cannot slip and be placed in the centre of
the trailer/caravan if possible, i.e. above
the axle.
In the case of trailers with low driving
stability, do not exceed a speed of 80 km/h;
the use of a friction-type stabiliser is
strongly recommended.
