Automatic anti-dazzle mirrors
G
WARNING
If inciden tlight fro mheadlamps is prevented
from striking the sensor in the rear-view mir-
ror, for instance, by luggage piled too high in
the vehicle, the mirror's automatic anti-dazzle
function will not operate.
Incident light could then blind you. This may
distract you from the traffic conditions and,
as a result, you may cause an accident.
The rear-view mirror and the exterior mirror
on the driver's side automatically go into anti-
dazzle mode if the ignition is switched on and
inciden tlight fro mheadlamps strikes the sen-
sor in the rear-view mirror.
The mirrors do not go into anti-dazzle mode if
reverse gear is engaged or the interior lighting
is switched on. Parking position for the exterior mir-
ror on the front-passenger side
Setting and storing the parking position You can position the front-passenger side
exterior mirror in such a way that you can see

Storing settings
With the memory function, you can store up
to three different settings, e.g. for three dif-
ferent people.
The following settings are stored as a single
memory preset:
R position of the seat, backrest and head
restraint
R driver's side: steering wheel position
R driver's side: position of the exterior mir-
rors on the driver's and front-passenger
sides G
WARNING
The memory function can still be used when
the key has been removed. For this reason,
children should never be left unsupervised in
the vehicle. They could otherwise become
trapped when adjusting the seat or the steer-
ing wheel. G
WARNING
Only use the memory function on the driver's
side when the vehicle is stationary. Other-
wise, you could be distracted from the traffic
conditions by the steering wheel and seat
moving of their own accord, and as a result
cause an accident. X

You will hear a warning tone if this is the
case.
R on vehicles with manual transmission, if
you shift to a higher gear and as a result the
engine speed is too low. G
WARNING
It is not possible to deactivate variable Speed-
tronic by braking.
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 ( Ypage 241).
Shortly before the store dspeed 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
Important safety notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the dis-
tance to the vehicle detected in front. It
brakes automatically in order to avoid
exceeding the set speed.
On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer,
you must select shift range 1,2or 3in good
time. By doing so, you will make use of the
braking effec tofthe engine. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
If a slower-moving vehicle is detected in front,
DISTRONIC PLUS causes your vehicle to brake and maintain the preset distance to the
vehicle in front. G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
DISTRONIC PLUS is only an aid designed to
assist driving. The driver remains fully respon-
sible for the vehicle's distance from other
vehicles, the vehicle's speed and for braking
in good time.
DISTRONIC PLUS does not react in particular
to:
R pedestrians
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossing traffic
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front,e .g. motorcycles, or vehi-
cles driving on a different line. Therefore,
always pay attention to traffic conditions even
when DISTRONIC PLUS is activated. Other-
wise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others. G
WARNING
DISTRONIC PLUS cannot take account of road
and traffic conditions. If DISTRONIC doe snot
recognise or no longer recognises the vehicle
in front, do not activate DISTRONIC or, if it is
already active, deactivate it. This is especially
the case:
R before corners
R on filter lanes
R when changing to a lane with faster moving
traffic
R in complex driving situations or where lanes
are diverted, e.g. at roadworks on a motor-
way Driving systems

Pulling away
X
If the vehicle in front pulls away: remove
your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you ?.
or
X Accelerate briefly.
Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
Driving
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control.
If a slower-moving vehicle is detected in front,
DISTRONIC causes your vehicle to brake. This
maintains the preset distance to the vehicle
in front.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed
of your vehicle, but only up to the desired
speed you have stored. G
WARNING
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary.
DISTRONIC PLUS then no longer brakes your
vehicle. In such cases, control the distance
from vehicles travelling in front with the brake
alone. You could otherwise cause an accident
and thereby injure yourself and others. The
driver remains fully responsible for the vehi-
cle's distance from other vehicles, the speed
being driven and for braking in good time.
Changing lanes
If you wish to change to the passing lane (in
countries where traffic drives on the right, the
passing lane is the left-hand lane), DIS-
TRONIC PLUS supports you if:
R you are driving faster than 60 km/h.
R DISTRONIC PLUS is maintaining the dis-
tance to a vehicle in front.
R you switch on the appropriate turn signals.
R DISTRONIC PLUS does not detect a danger
of collision. If these conditions are met, your vehicle is
accelerated. Acceleration will be interrupted
if changing lanes takes too long or if the dis-
tance between your vehicle and the vehicle in
front becomes too small. G
WARNING
DISTRONIC PLUS and Active Blind Spot Assist
are only an aid designed to assist driving.
They do not relieve you of the responsibility
of paying attention. The driver remains fully
responsible for the vehicle's distance from
other vehicles, the vehicle's speed and for
braking in good time. Always pay attention to
traffic conditions and your surroundings. Oth-
erwise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others.
Vehicles with COMAND Online
i The following function is not operational
in all countries.
DISTRONIC PLUS uses additional information
from your navigation system so that it can
react appropriately to certain traffic situa-
tions. This is the case if, while following a
vehicle, DISTRONIC PLUS is active and you:
R approach or drive through aroundabout
R approach a T junction
R turn off at a motorway exit
Even if the vehicle in front leaves the detec-
tion range, DISTRONIC PLUS temporarily
maintains the current driving speed and does
not accelerate. This is based on the current
map data in the navigation system. 186

increasing lapses in concentration, you will be
warned again after 15 minutes at the earliest.
ATTENTION ASSIST is reset and starts
assessing your tiredness again when you con-
tinue your journey if:
R you switch off the engine.
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break. Speed Limit Assist
Important safety notes Speed Limit Assist shows you detected speed
limits in the multifunction display. Data from
the navigation system is also used for this
purpose. The display appears if a traffic sign
indicating a speed limit or the end of a speed
limit is detected. If Speed Limit Assist does
not detec tany traffic signs, the speed limit
from the digital road ma pis taken and shown
in the display.
Speed Limit Assist detects the traffic signs
with a camera attached behind the top of the
windscreen. :
Speed Limit Assist camera G
WARNING
Speed Limit Assist is only an aid and may
detect speed limit signs incorrectly or not at
all.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to snow,
rain, fog or spray.
R there is glare, e.g. from the sun or from
oncoming traffic.
R the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera.
R the traffic signs are covered, for instance
by dirt, snow or trees. 204
