tLight System
General notes The Intelligent Light System is
asystem that
adjusts the headlamps automatically to suit the
prevailing driving and weather conditions. It
offers advanced functions for improved illumi-
nation of the road surface, e.g. depending on the vehicle speed or weather conditions. The sys-
tem includes the active light function, cornering light function, motorway mode, extended range
foglamps and off-road lights. The system is only
active when it is dark.
You can activate or deactivate the "Intelligent
Light System" function using the on-board com- puter (Y page 247).
Active light function The active light function is
asystem that moves
the headlamps according to the steerin gmove-
mentsoft he front wheels. In this way, relevant
areas remain illuminated while you are driving.
This allows you to recognise pedestrians,
cyclists and animals.
Active: when the lights are switched on.
Cornering light function The cornering light function improves the illu-
mination of the road over
awide angle in the
direction you are turning, enabling better visi-
bility in tight bends, for example. It can only be
activated when the dipped-beam headlamps are
switched on.
Active:
R if you are driving at speeds below 40 km/h
and switch on the turn signal or turn the steer- ing wheel
R if you are driving at speeds between 40 km/h
and 70 km/ha nd turnthe steering wheel
The cornering light function may remain lit for a
shor ttime, but is automatically switched off
after no mor ethant hree minutes. Motorwa
ymode Active:
if you are driving at aspee dabove
11 0k m/ hand do no tmakea ny large steering
movements for at least 1000 morify ou are
driving at aspee dabov e130 km/h.
Not active: if you are driving at speeds below
80 km/h followin gactivation.
Extended range foglamps The extended range foglamps reduc
ethe glare
experienced by th edriver and improve th eillu-
minatio noftheedge of th ecarriageway.
Active: if you are driving at speeds below
70 km/h and you switch on th erear foglamp.
Not active: if, followingactivation ,you are driv-
ing at speeds abov e100 km/h or if you switch
off th erear foglamp. Adaptive Highbeam Assist Plus
General notes Wit
hA daptiv eHighbeam Assist Plus, you can
automatically switch between dipped-beam,
partial main-beam and main-beam headlamps.
Partial main-beam illuminatio nisaformofi llu-
minatio nwhereby th emain beam is directed
past other road users. Other road user sare kept

there is avehicle in front, for example, th emain-
beam headlamps illuminate th eareas to its right

The system automatically adapt sthe dipped-
beam headlam prange dependin gonthedis-
tance to th eother vehicle .Oncet he system no

Ionisation is used to purify and freshen the air in the vehicle interior, which is conducive to a
pleasant climate.
The ionisation of the interior air is odourless and
cannot,d irectly, be perceived in the vehicle inte-
rior.
You can switch ionisation on or off using the
multimedia system (Y page 300).
Ionisation can only be operated when the auto-
matic climate control is switched on. The side air vent on the driver's side must be open. Auxiliary heating
Important safety notes G
DANGER
If the exhaust pipe is blocked or sufficient
ventilation is not possible, toxic exhaust
fumes can enter the vehicle, especially car-
bon monoxide. This is the case, e.g. in
enclosed spaces, or if the vehicle is stuck in
snow. There is arisk of fatal injuries.
You should switch off the auxiliary heating in
enclosed spaces which do not have an extrac- tion system, e.g. agarage. If the vehicle is
stuck in snow and you must leave the auxiliary
heating running, keep the exhaust pipe and the area around the vehicle clear of snow. To
guarantee asufficient supply of fresh air, open
aw indow on the side of the vehicle away from
the wind. G
WARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot.
Flammable materials such as leaves, grass or twigs may ignite if they come into contact
with:
R hot parts of the exhaust system
R the exhaust gas itself
There is arisk of fire.
When the auxiliary heating is switched on,
make sure that:
R no flammable materials come into contact
with hot vehicle components
R the exhaust gas can escape from the
exhaust pipe unhindered
R the exhaust gas does not come into contact
with flammable materials.
The auxiliary heating is fitted under the front
wing on the right-han dside of the vehicle. The
emissions outlet is found behind the front wheel on the right-han dside of the vehicle. 138
