For reason sofsafety, Mercedes-Ben zrecom-
mends that you driv ewith th elight sswitched on

road to th ecountr yinw hichthe vehicle is reg-
istered ,your headlamps must be switched to
symmetrical dipped beam as soon as possible
after crossing th eborder (only vehicle swith
Intelligen tLigh tSystem). This prevent soncom-
ing traffic from bein gdazzled. Symmetrical
light sdon otilluminate as large an area of the
edge of th ecarriageway.
Vehicles with halogen or static LED

to symmetrical dipped beam and after returning
back to asymmetrical dipped beam via the
"Dipped-beam headlamps for driving on the

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
out of th emain-beam. This prevent sglare .If
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

Switching SPEEDTRONIC to passive
If you depress the accelerator pedal beyond the
pressure point (kickdown), SPEEDTRONIC is
switched to passive mode. The SPEEDTRONIC SPEEDTRONIC
suspended
suspended message appears in the multifunc-
tion display.
You can then exceed the stored speed. SPEED-
TRONIC is activated again if you:
R drive slower than the stored speed without
kickdown
R set anew speed or
R call up the last speed stored again
The SPEEDTRONIC suspended SPEEDTRONIC suspended message in the
multifunction display disappears.
Deactivating variable SPEEDTRONIC
It is not possible to deactivate variable SPEED-
TRONIC by braking.
There are several ways to deactivate variable
SPEEDTRONIC:
X Briefly press the cruise control lever forwards
B.
or X Briefly press the cruise control lever in the
direction of arrow A.
LIM indicator lamp ;in the cruise control
lever goes out. Variable SPEEDTRONIC is
deactivated.
Cruise control or DISTRONIC PLUS is selec-
ted.
i The last speed stored is cleared when you
switch off the engine.
Permanent SPEEDTRONIC
You can use the on-board computer to limit the
speed permanently to avalue between
160 km/h(e.g. for driving on winter tyres) and
the maximum speed (Y page 248).
Shortly before the stored speed is reached, it
appears in the multifunction display.
Permanent SPEEDTRONIC remains active, even
if variable SPEEDTRONIC is deactivated.
You cannot exceed the stored limit speed, even if you depress the accelerator pedal beyond the
pressure point (kickdown). DISTRONIC PLUS
General notes DISTRONIC PLUS regulates the speed and auto-
matically helps you maintain the distance to the
vehicle detected in front.V ehicles are detected
with the aid of the radar sensor system.
DISTRONIC PLUS brakes automatically so that
the set speed is not exceeded.
Change into alower gear in good time on long
and steep downhill gradients. Take particular
note of this when driving aladen vehicle. By
doing so, you will make use of the braking effect
of the engine. This relieves the load on the brake
system and preventst he brakes from overheat-
ing and wearing too quickly.
If DISTRONIC PLUS detectst hat there isarisk of
ac ollision, you will be warned visuallya nd
acoustically. Without your intervention,
DISTRONIC PLUS cannot prevent acollision. An
intermittent warning tone will then sound and
the distance warning lamp will light up in the
instrumen tcluster. Brake immediately to
increase the distance to the vehicle driving in
front,ort ake evasive action, provided it is safe
to do so.
DISTRONIC PLUS operates in the range
between 0km/h and 200 km/h.
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
Important safety notes G
WARNING
DISTRONIC PLUS does not react to:
R people or animals
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncominga nd crossing traffic
As aresult, DISTRONIC PLUS may neither give
warnings nor interveneins uch situations.
There is arisk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. G
WARNING
DISTRONIC PLUS cannot always clearly rec-
ognise other road users and complex traffic
conditions. 184
