is
turned on » page 82, Windscreen wipers and washers .
The windscreen wipers are on for more than 30 s.
The light turns off about 4 minutes after turning off the wipers.
The function can be activated/deactivated in the Infotainment » Infotainment
manual , chapter Vehicle settings (CAR button) .
CAUTION
Do not attach any stickers or similar objects in front of the light sensor on the
windscreen to avoid impairing the function or its reliability.
Adaptive headlights (AFS)
Read and observe
on page 71 first.
The AFS system makes sure the street remains lit up depending on the traffic
and weather situation.
The AFS system automatically adjusts the cone of light in front of the vehicle
based on the vehicle speed, whether the windscreen wipers are in use, the
rear fog lights, and data from Infotainment Navigation.
The AFS system works as long as the light switch is in position
» page 73 .
The AHL system operates in the following modes.
Out of town mode
The cone of light in front of the vehicle is similar to the low beam.
City mode
The cone of light in front of the vehicle is adjusted so that it illuminates the
adjacent pavement, crossings, etc. The mode is active at speeds of 15-50 km/h.
Motorway mode
The cone of light in front of the vehicle is adjusted so that the driver can re-
spond in time to an obstruction or other hazard in time. The mode is active at
speeds above 110 km/h.
Rain mode
The cone of light in front of the vehicle is adjusted so that the driver can re-
duce the glare from oncoming vehicles in rain.
The mode is active at speeds of 50 – 90 km/h and if the windscreen wipers
continuously operate for a period of time longer than 2 minutes. The mode is
deactivated when the windscreen wipers are switched off for longer than 8
minutes.
Fog mode
The cone of light in front of the vehicle is adjusted so that the driver is not
dazzled by the reflection of the cone of light by fog in front of the vehicle.
The mode is active at speeds of 15 – 70 km/h and if the rear fog light is switch-
ed on for a period of time longer than 10 seconds. The mode is deactivated
when the rear fig light is switched off for longer than 5 seconds.
Dynamic cornering lights
The cone of light in front of the vehicle is adjusted to the steering angle so
that the road in the curve is illuminated. This function is active at speeds
greater than 10 km.h and in all AFS modes.
travel mode (“tourist light”)
This mode makes it possible to drive in countries with opposing traffic system
(driving on the left/right) without dazzling the oncoming vehicles.
When this mode is active, the above-mentioned modes and the side swivel of
the headlights is deactivated.
This mode can be activated/deactivated in the Infotainment » Infotainment
operating instructions , chapter Vehicle settings (CAR button) .WARNINGIf the AFS system is defective, the headlights are automatically lowered to
the emergency position, which prevents a possible dazzling of oncoming
traffic. This reduces the cone of light in front of the vehicle. Drive carefully
and visit a specialist garage as soon as possible.
Note
If the Eco driving mode is selected, the AFS system is deactivated » page 160.74Using the system

S
- mode for driving forward (Normal program) / mode for driving
forward (Sport program)
The system switches from one mode to the other by moving the selector lever
into the spring-loaded position
» Fig. 134 .
In mode D or S, the forward gears are shifted automatically depending on the
engine load, the operation of the accelerator pedal, the vehicle speed, and the
selected driving mode .
In mode S , the forward gears are shifted automatically up and down at high-
er engine speeds than in mode D.
If the Sport driving mode is selected with the engine running » page 160, Se-
lection of travel mode (Driving Mode Selection) , the transmission is automati-
cally set in the S mode.
E – Economical driving mode
If the driving mode Eco or Individual (engine - Eco) » page 160 is selected and
the selection lever is in the setting D/S, transmission is automatically set in
mode E . This mode cannot be selected with the selector lever.
In mode E , the forward gears are shifted automatically up and down at lower
engine speeds than in mode D.
Selector lever lock
Read and observe
and on page 133 first.
The selector lever is locked in mode P and N to prevent that the forward driv-
ing is selected accidentally, thereby setting the vehicle in motion.
The selector lever is locked only when the vehicle is stationary and at speeds
up to 5 km/h.
The selector lever lock is indicated by the illumination of the warning light .
The selector lever is not locked when quickly moving across the position N
(e.g. from R to D/S ). This, for example, helps to rock out a vehicle that is stuck,
e.g. in a bank of snow. The selector lever lock will engage if the lever is in posi-
tion N for more than approx. 2 seconds without the brake pedal being de-
pressed.
Releasing selector lever from mode P or N (selector lever lock)›Press the brake pedal and the lock button at the same time in the direction
of 1
» Fig. 134 on page 133 .
Just depress the brake pedal, if you would like to change from the mode N to
D/S .
Defective selector lever lock
If the selector lever lock is defective or its power supply is interrupted (e.g. dis-
charged vehicle battery, faulty fuse), the selector lever can no longer be moved
out of position P in the normal manner and the vehicle can no longer be driven.
The selector lever must be unlocked specially » page 226.
Note
If you want to move the selector lever from mode P to mode D/S or vice versa,
move the selector lever quickly. This prevents that you accidentally select
mode R or N.

Note
■ It may be beneficial, for example, when travelling downhill, to use manual
shifting of gears. Shifting to a lower gear reduces the load on the brakes and
hence the wear of the brakes » page 130.■
When accelerating, the gearbox automatically shifts up into the higher gear
just before the maximum permissible engine speed is reached.
■
If a lower gear is selected, the gearbox does not shift down until there is no
risk of the engine overrevving.
