At low ambient temperatures, the exterior
rear view mirrors will be heated
automatically. Auto-dimming rear view mirrors
The exterior rear view mirror on the driver’s
side and the interior rear view mirror will
respond automatically to glare when the
ignition is switched on and incoming light
from headlamps falls on the sensor in the
interior rear view mirror.
The rear view mirrors will not react if the
automatic transmission is set to reverse gear
R or the interior lighting is switched on. G
Warning!
The auto dimming function does not react if
incoming light is not aimed directly at sensors
in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, if the rear window
sunshade is in raised position.
Light hitting the mirror(s) at certain angles
(incident light) could blind you. As a result,
you may not be able to observe traffic
conditions and could cause an accident. Exterior rear view mirror parking

Notes
! Do not operate the wipers when the
windshield is dry. Dust that accumulates on
a windshield might scratch the glass and/
or damage the wiper blades when wiping
occurs on a dry windshield. If it is necessary
to operate the wipers in dry weather
conditions, always operate the wipers with
washer fluid.
! If the windshield wipers leave smears on
the windshield after the car has been driven
through an automatic car wash, then wax
or other residue is on the windshield.
Shortly after washing the car in an
automatic car wash, clean the windshield
with washer fluid. Windshield wipers

sensor is activated. The rain sensor sets a
suitable wiping interval depending on the
wetness of the sensor surface automatically.
! Do not leave windshield wipers on an
intermittent setting when the vehicle is
taken to an automatic car wash or during
windshield cleaning. Windshield wipers will
operate in the presence of water sprayed
on the windshield, and windshield wipers
may be damaged as a result.
! If you have set intermittent wiping, dirt on
the surface of the rain sensor or optical
effects may cause the windshield wipers to
wipe in an undesired fashion. This could
then damage the windshield wiper blades
or scratch the windshield. You should
therefore switch off the windshield wipers
when weather conditions are dry.

Safety notes When activated, the DISTRONIC PLUS
adaptive
cruise
control system increases the
driving convenience afforded by the cruise
control while traveling on expressways and
other major roadways.
R If the DISTRONIC PLUS distance sensor
detects a slower moving vehicle directly
ahead, your vehicle speed will be reduced
so that you follow that vehicle at your
preset following distance.
R If there is no vehicle directly ahead of you,
the DISTRONIC PLUS will function in the
same way as standard cruise control
(Y page 302). G
Warning!
The DISTRONIC PLUS requires familiarity with
its operational characteristics. We strongly
recommend that you review the following
information carefully before operating the
system. 304

G
Warning!
When the DISTRONIC PLUS is braking, the
brake pedal is retracted (i.e. depressed
automatically). The pedals’ range of motion
must not be impeded by any obstacles:
R Do not place any objects in the footwell.
R Make sure that the floormats and carpets
are securely in place.
R Do not
rest your foot underneath the brake
pedal, as it could otherwise be trapped.
You could otherwise cause an accident and
injure yourself and/or others. G
Warning!
The DISTRONIC PLUS is a convenience
system. Its speed adjustment reduction
capability is intended to make cruise control
more effective
and usable when traffic speeds
vary. It is not however, intended to, nor does
it, replace the need for extreme care.
The responsibility for the vehicle’s speed,
distance to the preceding vehicle and, most
importantly, brake operation to ensure a safe
stopping distance, always remains with the
driver.
The DISTRONIC PLUS cannot take street and
traffic conditions into account.
Complex driving situations are not always
fully recognized by the DISTRONIC PLUS. This
could result in wrong or missing distance
warnings. G
Warning!
The DISTRONIC PLUS adaptive cruise control
is not a substitute for active driving
involvement. It does not react to pedestrians
or on
stationary objects, nor does it recognize
or predict the curvature and lane layout or the
movement of preceding vehicles. The
DISTRONIC PLUS can only apply a maximum
of 40% of the vehicle’s braking power.
The DISTRONIC PLUS may not detect narrow
vehicles possibly driving in front of you, such as motorcycles and vehicles driving in an
offset formation.
It is the driver’s responsibility at all times to
be attentive to the road, weather and traffic
conditions. Additionally, the driver must
provide
the
steering, braking and other driving
inputs necessary to remain in control of the
vehicle.
High-frequency sources such as toll stations,
speed measuring systems etc. can cause the
DISTRONIC PLUS system to temporarily
cease functioning. G
Warning!
The DISTRONIC PLUS cannot take road and
traffic conditions into account. Only use the
DISTRONIC PLUS if the road, weather and
traffic conditions make it advisable to travel
at a constant speed. G
Warning!
Use of the DISTRONIC PLUS can be
dangerous on slippery roads. Rapid changes
in tire traction can result in wheel spin and
loss of control.
The DISTRONIC PLUS does not function in
adverse sight
and distance conditions. Do not
use the DISTRONIC PLUS during conditions of
fog, heavy rain, snow or sleet. G
Warning!
The DISTRONIC PLUS cannot take weather
conditions into account. Switch off the
DISTRONIC PLUS or do not switch it on if:
R roads are
slippery or covered with snow or
ice. The wheels could lose traction while
braking or accelerating, and the vehicle
could skid.
R the DISTRONIC PLUS system sensor covers
are dirty or visibility is diminished due to
snow, rain or fog, for example. The distance
control system functionality could be
impaired.
Always pay attention to surrounding traffic
conditions even while the DISTRONIC PLUS is Driving systems

switched on. Otherwise, you may not be able
to recognize dangerous situations until it is
too
late.
This could cause an accident in which
you and/or others could be injured. G
Warning!
The “Resume” function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed. G
Warning!
Close attention to road and traffic conditions
is imperative at all times, regardless of
whether or not the DISTRONIC PLUS is
activated.
Use of the DISTRONIC PLUS can be
dangerous on
winding roads or in heavy traffic
because conditions do not allow safe driving
at a constant speed.
The DISTRONIC PLUS will not react to
stationary objects in the roadway (e.g. a
stopped vehicle in a traffic jam or a disabled
vehicle). The DISTRONIC PLUS will also not
respond to oncoming vehicles.
Switch off the DISTRONIC PLUS:
R when changing from the left to the right
lane if vehicles are moving more slowly in
the left lane
R when entering a turn lane or highway off
ramp
R in complex driving situations, such as in
highway construction zones
In these situations, the DISTRONIC PLUS will
continue to maintain the set speed unless
deactivated.
The DISTRONIC PLUS is designed and
intended only to maintain a set speed and
keep a set distance from moving objects in
front of it.
The DISTRONIC PLUS functions in a speed
range of 0 to 120 mph
(Canada: 0 to 200 km/h) if a preceding
vehicle is detected. If no preceding vehicle is
detected the DISTRONIC PLUS functions in a speed range of 20 to 120 mph
(Canada: 30 to 200 km/h).
Always obey applicable speed limits.
Do not use the DISTRONIC PLUS if you are
driving
on
a road with steep uphill or downhill
slopes.
When traveling in Canada in a vehicle not
registered in Canada, you must switch off the
radar sensor system ( Y page 216). Canadian
law does not permit the use of the radar
sensor system for vehicles from outside of
Canada. When you switch off the radar sensor
system, the following functions are
deactivated:
R DISTRONIC PLUS
R BAS PLUS (Y page 57)
R PRE-SAFE ®
Brake (Y page 62)
R Park Assist ( Y page 324)

i Due to its radar-emitting nature
DISTRONIC PLUS may have an appearance
similar to a radar detector to law
enforcement officials. You may want to
refer to this section of your Operator’s
Manual when asked.
