!
Do not operate the windshield wipers when
the windshield is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windshield/rear window can
scratc hthe glass if wiping takes place when
the windshield/rear window is dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, alwaysu se
washer fluid when operating the windshield
wipers.
!If the windshield wipers leave smears on the
windshield/rear window after the vehicle has
been washed in an automatic car wash, this
may be due to wax or other residue. Clean the
windshield/rear window with washer fluid
after an automatic car wash.
!Intermittent wiping with rain sensor: due to
optical influences and the windshield becom-
ing dirty in dry weather conditions, the wind-
shield wipers may be activated inadvertently.
This could then damage the windshield wiper
blades or scratc hthe windshield.
For this reason, you should alwayss witch off
the windshield wipers in dry weather.

to the intensity of the rain. In the Åposition,
the rain sensor is more sensitiv ethan in the

wipe more frequently.
Intermittent wiping is interrupted if you stop the vehicle and open afront door. This protects
people getting into and out of the vehicle from
being sprayed with water.

Important safetyn otes
GWARNING
DISTRONIC PLUS does not react to:
Rpeople or animals
Rstationary obstacles on the road, e.g. stop- ped or parked vehicles
Roncoming and crossing traffic
As aresult, DISTRONIC PLUS may neither give
warning snor interveneins uch situations.
There is arisk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
GWARNING
DISTRONIC PLUS cannot always clearly iden-
tify other road users and complex traffic sit-
uations.
In such cases, DISTRONIC PLUS may:
Rgive an unnecessary warning and then
brake the vehicle
Rneither give awarning nor intervene
Raccelerateorb rake unexpectedly
There is arisk of an accident.
Continue to drive carefully and be ready to
brake, in particular when warned to do so by
DISTRONIC PLUS.
GWARNING
DISTRONIC PLUS brakes your vehicle with up to 40% of the maximum brakin gforce. If this
brakin gforceisi nsufficient ,DISTRONIC PLUS
warns you visually and audibly. There is arisk
of an accident.
In such cases, apply the brakes yourself and
try to take evasive action.
If you fail to adapt your driving style, DISTRONIC
PLUS can neither reduce the risk of an accident
nor override the laws of physics. DISTRONIC
PLUS cannot take accountofr oad, weather and
traffic conditions. DISTRONIC PLUS is only an
aid. You are responsible for maintaining asafe
distanc etothe vehicle in front, for vehicle
speed, for brakin gingood time and for staying in
lane.
Do not use DISTRONIC PLUS:
Rin road and traffic condition sthat do not allow
you to maintain aconstan tspeed, e.g. in
heavy traffic or on winding roads
Ron slippery road surfaces.B raking or accel-
eratin gcan cause the drive wheels to lose
traction and the vehicle could then skid

obstacle or stationary vehicle, DISTRONIC
PLUS will not brake for these.
RCrossing vehicles: DISTRONIC PLUS may mis-
takenly detect vehicles that are crossingyour
lane. Activating DISTRONIC PLUS at traffic
lights with crossingt raffic,for example, could
cause your vehicle to pull away unintention-
ally.
In such situations, brake if necessary.
DISTRONIC PLUS is then deactivated.
Blind Spot Assist
General notes
Blind Spot Assist monitor sthe areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facingr adar sen-
sors. Awarning lamp lights up in the exterior
mirrors and draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lane, you will also receive an optical and
audiblew arning.
Blind Spot Assist supports you from aspeed of
approximately 20 mph (30 km/h).
Important safety notes
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with alarge speed
differential and overtak eyour vehicle
As aresult, Blind Spot Assist may not give
warnings in such situations. There is arisk of
an accident.
Always observe the traffic conditions care-
fully, and maintain asafe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.
iUSA only:
This device has been approved by the FCC as
a" Vehicular RadarS ystem". The radar sensor
is intended for use in an automotive radar system only. Removing, tampering with, or
altering the device will void any warranties,
and is not permitted by the FCC. Do not tam-
per with, alter, or use in any non-approved
way.
Any unauthorized modification to this device
could void the user’s authority to operate the
equipment.
Radar sensors
The radar sensors for Blind Spot Assist are inte-
grated into the rear bumper. Make sure that the
bumpers are free from dirt, ice or slush. The
sensors must not be covered, for example by
cycle racks or overhanging loads. Following a
severe impact or in the event of damage to the
bumpers, have the function of the radar sensors
checked at aqualified specialist workshop.
Blind Spot Assist may no longer work properly.
Monitoring area
In particular, the detection of obstacles can be
impaired if:
Rthere is dirt on the sensors or anything else
coveringt he sensors
Rthere is poor visibility, e.g. due to fog, heavy
rain, snow or spray
Rthere are narrow vehicles, e.g. motorcycles or
bicycles
Rthe road has very wide lanes
Rthe road has narrow lanes
Ryou are not driving in the middle of the lane
Rthere are barriers or other road boundaries

!When testing the parking brake, operate the
vehicle only briefly (for amaximum of ten sec-
onds) on abrake test dynamometer. When
doing this, turn the SmartKey to position 0or
1 in the ignition. Failure to do this can cause
damage to the drive train or the brake system.
!Af unction or performance test should only
be carried out on atwo-axle dynamometer.
Before you operate the vehicle on such a
dynamometer, please consult aqualified
workshop. You could otherwise damage the
drive train or the brake system.
The all-wheel drive system ensures that all four
wheels are permanently driven. The all-wheel
drive system improves vehicle traction together
with ESP
®and 4ETS if adrive wheel spins due to
insufficient grip.
If ad rive wheel spins due to insufficient grip:
ROnly depress the accelerator pedal as far as
necessary when pulling away.
RTake your foot off the accelerator, slowly,
while the vehicle is in motion.
Only when you use winter tires (M+S tires) and, if necessary, snow chains in wintry driving con-
ditions (
Ypage 253). Only in this way can the
maximum effect of all-wheel drive be achieved.
For information on driving off-road, see
(
Ypage 127).
PARKTRONIC
Important safety notes
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area around
your vehicle using six sensors in the front
bumper and four sensors in the rear bumper.
PARKTRONIC indicates visually and audibly the
distance between your vehicle and an object.
PARKTRONIC is only an aid. It is not areplace-
ment for your attention to your immediate sur-
roundings. You are always responsible for safe
maneuvering, parking and exiting aparking
space. Make sure that there are no persons,
animals or objects in the maneuvering area
while maneuvering and parking in parking
spaces.
!When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. PARKTRONIC
does not detect such objects when they are in the immediate vicinity of the vehicle. You
could damage the vehicle or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes on
atruck
or ap neumatic drill could cause PARKTRONIC
to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is activated automaticallyw hen
you:
Rswitch on the ignition
Rshift the transmission to position D,Ror N
Rrelease the parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.
Range of the sensors
PARKTRONIC does not take objects into con-
sideration that are:
Rbelow the detection range, e.g. people, ani-
mals or objects.
Rabove the detection range, e.g. overhanging
loads, tail sections or loading ramps of goods
