If you fail to adapt your drivin gstyle or if you
are inattentive ,th edrivin gsafet ysystems can
neither reduce th eris kof an acciden tno r
override th elaws of physics. Driving safet y
systems are merely aids designed to assist
driving. You are responsible fo rmaintainin g
th edistanc eto th evehicle in front, fo rvehicle
speed, fo rbraking in goo dtime, and fo rstay-
in gin lane. Always adapt your drivin gstyle to
suit th eprevailin groad and weather condi-
tion sand maintain asaf edistanc efrom th e
vehicle in front. Drive carefully.
The drivin gsafet ysystems described only
wor kas effectively as possible when there is
adequat econtact between th etires and th e
road surface. Please pay special attention to
th enote son tires ,recommended minimum
tire tread depths, etc. (
Ypage 328).
In wintr ydrivin gconditions, always use winte r
tires (M+ Stires )and if necessary, snow
chains. Only in this way will th edrivin gsafet y
systems described in this section wor kas
effectively as possible.
ABS (Anti-lock Braking System)
General information

AB Sworks from aspeed of about 5mph
(8 km/h), regardles sof road-surfac econdi-
tions. AB Sworks on slipper ysurfaces, eve n

Other vehicles changing lanes
DISTRONIC PLUS has not detected the vehi-
cle cutting in yet. The distance to this vehicle
will be too short.
Narrow vehicles
DISTRONIC PLUS has not yet detected the
vehicle in front on the edge of the road,
because of its narrow width. The distance to
the vehicle in front will be too short.
Obstructions and stationary vehicles
DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example, thedetected vehicle turns a corner and reveals
an obstacle or stationary vehicle, DISTRONIC
PLUS will not brake for these.
Crossing vehicles
DISTRONIC PLUS may detect vehicles that
are crossing your lane by mistake. Activating
DISTRONIC PLUS at traffic lights with cross-
ing traffic, for example, could cause your vehi-
cle to pull away unintentionally.
HOLD function
General notes
The HOLD function can assist the driver in the
following situations:
Rwhen pulling away, especially on steep
slopes
Rwhen maneuvering on steep slopes
Rwhen waiting in traffic
The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.

Problems with PARKTRONIC
ProblemPossible causes/consequences andMSolutions
Only the red segments
in the PARKTRONIC
warning displays are lit.
You also hear a warning
tone for approximately
two seconds.
PARKTRONIC is then
deactivated and the
indicator lamp on the
PARKTRONIC button
lights up.PARKTRONIC has malfunctioned and has switched off.
XIf problems persist, have PARKTRONIC checked at a qualified
specialist workshop.
Only the red segments
in the PARKTRONIC
warning displays are lit.
PARKTRONIC is then
deactivated.The PARKTRONIC sensors are dirty or there is interference.
XClean the PARKTRONIC sensors (Ypage 305).
XSwitch the ignition back on.
The problem may be caused by an external source of radio or
ultrasound waves.
XSee if PARKTRONIC functions in a different location.
Active Parking Assist
General notes
Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle. A parking symbol
indicates a suitable parking space. Active
steering intervention and brake application
can assist you during parking and when exit-
ing a parking space. You may also use
PARKTRONIC (
Ypage 192).
Important safety notes
Active Parking Assist is merely an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting a parking space. Make sure that
no persons, animals or objects are in the
maneuvering range.
When PARKTRONIC is switched off, Active
Parking Assist is also unavailable.
GWARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
result in a collision with another road user.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
!If unavoidable, you should drive over
obstacles such as curbs slowly and not at a
sharp angle. Otherwise, you may damage
the wheels or tires.
Active Parking Assist may possibly indicate
parking spaces which are not suitable for
parking, for example:
RWhere parking or stopping is prohibited
RIn front of driveways or entrances and exits
ROn unsuitable surfaces

ATTENTION ASSIST
General notes
ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways.
It is active in the 37 mph (60 km/h) to
125 mph (200 km/h) range. If ATTEN-
TION ASSIST detects typical indicators of fati-
gue or increasing lapses in concentration on
the part of the driver, it suggests taking a
break.
Important safety notes
ATTENTION ASSIST is only an aid to the
driver. It might not always recognize fatigue
or increasing inattentiveness in time or fail to
recognize them at all. The system is not a
substitute for a well-rested and attentive
driver.

The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or
not occur at all:
Rif the length of the journey is less than
approximately 30 minutes
Rif the road condition is poor, e.g. if the sur-
face is uneven or if there are potholes
Rif there is a strong side wind
Rif you have adopted a sporty driving style
with high cornering speeds or high rates ofacceleration
Rif you are predominantly driving slower
than 37 mph (60 km/h) or faster than
125 mph (200 km/h)
Rif the time has been set incorrectly
Rin active driving situations, such as when
you change lanes or change your speed
ATTENTION ASSIST is reset when you con-
tinue your journey and starts assessing your
tiredness again if:
Ryou switch off the engine
Ryou take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break
Displaying the attention level
You can have current status information dis-
played in the assistance menu (
Ypage 219)
of the on-board computer.
XSelect the Assistance display for Attention
Assist using the on-board computer
(
Ypage 219). The following information is displayed:
Rlength of the journey since the last break.
Rthe attention level determined by ATTEN-
TION ASSIST (
Attention Level
), dis-
played in a bar display in five levels from
high to low
Rif ATTENTION ASSIST is unable to calculate the attention level and cannot issue a warn-
ing, the System Suspended
message
appears. The bar display then changes the
display, e.g. if you are driving at a speed
below 37 mph (60 km/h) or above 124 mph
(200 km/h) .
Activating ATTENTION ASSIST
