Adaptive Forward Lighting
3
(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.

Lead-me lighting when leaving the
vehicle 3
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.

110 LightingBattery discharge protection
3
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.
Vehicles with halogen headlamp system
or Xenon headlamp system 3
Have headlights conver ted in a workshop.

Vehicles with Adaptive headlight 3 (AFL)
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
B
will then discontinue flashing.

Driving and operation
Driving hintsThe first 1000 km
Drive your vehicle at various speeds. Do
not use full throttle. Never allow the engine
to labour at low revs.
Drive moderately. In all gears, only depress
the accelerator pedal around
3/4 of the way
down.
Do not drive faster than three quarters of
maximum speed.
Do not brake unnecessarily hard for the
first 200 km.
During the first drive smoke may develop
because of wax and oil evaporating on the
exhaust system. Park the vehicle in the
open for a while after the first drive and
avoid inhaling the fumes.
Fuel and engine oil consumption is higher
than normal during the running-in period.
Never coast with engine not running
Many units will not function in this situation
(e.g. brake servo unit, power steering 3).
Driving in this manner is a danger to
yourself and others. Brake servo unit
When the engine is not running, the brake
servo unit is no longer effective once the
brake pedal has been depressed once or
twice. Braking effect is not reduced, but
significantly greater force is required for
braking.
Electric power steering
3
If the power assisted steering fails when
being towed with the engine switched off,
the vehicle can still be steered, but
considerably more force is required.
Driving in mountainous terrain or with a
trailer/caravan
The cooling fan is elec trically operated. Its
cooling power is therefore independent of
the engine speed.
Since a considerable amount of heat is
generated at high engine speeds and less
at slower speeds, do not shift down when
climbing hills whilst the vehicle is still coping
with the gradient in the higher gear. Driving with a roof load
Do not exceed the permissible roof load
3
226. For reasons of safety, distribute the
load evenly and secure it properly with
retaining straps. Adjust tyre pressure to
load conditions. Do not drive faster
than 120 km/h. Check and retighten the
straps frequently. Observe country-specific
regulations.
Switching off the engine
When you switch off, fans in the engine
compartment may continue running for a
time to cool the engine.
If the engine temperature is very high, e.g.
after driving in mountainous terrain: allow
the engine to idle for approximately two
minutes in order to prevent heat
accumulation.
Vehicles with turbocharged engine
3
After running at high engine speeds or high
engine loads, operate the engine briefly
at a low load or run in neutral for
approx. 30 seconds before switching off in
order to protect the turbocharger.

Driving and operation
Control indicator
v
The warning light lights up for a few
seconds when ignition is switched on. Once
it goes out, the system is ready for
operation.
Flashing during driving:
This shows the system has come into
action. The engine output may be reduced
(the sound of the engine changes) and the
vehicle may be braked automatically to a
small degree.
Picture no: 17892s.tif
Illuminates while driving:
Fault in the system. Driving can be
continued. Poor road surface conditions
may however still cause vehicle stability to
be impaired.
Have the cause of the fault eliminated.
Self-diagnosis integrated into the system
allows rapid fault identification. Illuminates after interruption of power
supply e.g. after disconnecting battery.
After a power supply interruption the
steering angle sensor must be calibrated to
make the system operational:
z
Automatic calibration driving in straight
line at constant slow (20 to 40 km/h)
speed on level, dry road.
z Manual calibration by turning steering
wheel from limit position to limit position.
If the indicator lamp does not go off after
successful calibration , observe notes in
middle column.
Page 170 of 248

164 Driving and operationIf the trailer/caravan starts to sway, drive
more slowly, do not attempt to correct the
steering and brake sharply if necessary.
If it is necessary to apply the brakes fully,
depress the brake pedal as hard as
possible.
Remember that the braking distance for
vehicles towing carava ns/trailers with and
without brake is always greater than that
for vehicles not towing a caravan/trailer.
When driving downhill , drive in the same
gear as if driving uphill and drive at a
similar speed.
Adjust tyre pressure to the value specified
for full load 3228. Starting on inclines
For vehicles with ma
nual transmission,
the most favourable engine speed
when starting off on an incline is
between 2500 and 3000 rpm for petrol
engines and between 2000 and 2500 rpm
for diesel engines. Hold engine speed
constant, engage clutch gradually (let slip)
– release hand brake – and open throttle. If
possible, the engine speed should not drop
during this procedure.
For vehicles with ma nual transmission
automated 3 in Automatic mode simply
apply full gas. Before starting off under extreme
operating conditions, switch off
unnecessary consumers.

Screw in the towing eye anticlockwise as far
as it will go until it stops in a horizontal
position.
Attach a tow rope 3 – or better still a tow
rod 3 – to the eye.
The towing eye may only be used for
towing and not for recovery of the vehicle. Switch on ignition to release steering
column lock and to permit operation of
brake lamps, horn an
d windscreen wipers.
Gear lever in neutral.
Picture no: 17897s.tif
When the engine is not running,
considerably more force is needed to brake
and steer.
To prevent the entry of exhaust fumes from
the towing vehicle, switch on the air
recirculation 3 and close the windows.
Contact a workshop for assistance.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can damage
the vehicle.
