In this section ,you will fin dinformation about
th efollowin gdrivin gsafet ysystems :

Important safet ynotes
If you fail to adapt your drivin gstyle or if you are
inattentive ,th edrivin gsafet ysystems can nei-
ther reduce th eris kof an acciden tno roverride
th elaws of physics. Driving safet ysystems are
merely aids designed to assist driving. You are
responsible fo rmaintainin gth edistanc eto th e
vehicle in front, fo rvehicle speed, fo rbraking in
goo dtime, and fo rstayin gin lane. Always adapt
your drivin gstyle to suit th eprevailin groad and
weather condition sand maintain asaf edistanc e
from th evehicle in front. Drive carefully.
The drivin gsafet ysystems described only wor k
as effectively as possible when there is ade-
quat econtact between th etires and th eroad
surface. Please pay special attention to th e
note son tires ,recommended minimum tire
tread depths, etc. (
Ypage 282).
In wintr ydrivin gconditions, always use winte r
tires (M+ Stires )and if necessary, snow chains.
Only in this way will the driving safety systems
described in this section work as effectively as
possible.
ABS (Anti-lock Braking System)
General information
ABS regulates brake pressure in such a way that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when
braking. The
! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, even when you
only brake gently.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 60).
GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (
Ypage 218) and dis-
play messages which may be shown in the
instrument cluster (
Ypage 189).
Braking
XIf ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over.
XTo make a full brake application: depress
the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions, and functions as a reminder to take extra care while driving.
BAS (Brake Assist System)
General information
BAS operates in emergency braking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.

Safety

iFor design reasons, the speed displayed in
the speedometer may differ slightly from the
speed set for Distance Pilot DISTRONIC.

In the Assistance menu (Ypage 182 )of the on-
board computer, you can select the assistance
display.

Tips for driving with Distance Pilot
DISTRONIC
General notes
Pay particular attention in the following traffic
situations:
RCornering, entering and exiting a bend: the
ability of Distance Pilot DISTRONIC to detect
vehicles during cornering is limited. Your vehi-
cle may brake unexpectedly or late.
RDriving on a different line: Distance Pilot
DISTRONIC may not detect vehicles which are
not driving in the middle of their lane. The dis-
tance to the vehicle in front will be too short.
ROther vehicles changing lanes: Distance Pilot
DISTRONIC has not detected the vehicle cut-
ting in yet. The distance to this vehicle will be too short.
RNarrow vehicles: Distance Pilot DISTRONIC
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.
RObstacles and stationary vehicles: Distance
Pilot DISTRONIC does not brake for obstacles
or stationary vehicles. If, for example, the
detected vehicle turns a corner and an obsta-cle or stationary vehicle is then revealed, Dis-
tance Pilot DISTRONIC will not brake for
them.
RDistance Pilot DISTRONIC may mistakenly
detect vehicles that are crossing your lane. If
you activate Distance Pilot DISTRONIC in thefollowing situations, the vehicle could pull
away unintentionally:
-At traffic lights with crossing traffic, for
example.
-With a vehicle ahead on the other side of an
intersection and the HOLD function active.
In such situations, brake if necessary. Distance
Pilot DISTRONIC will then be deactivated.

Problems with Parking Assist PARKTRONIC
ProblemPossible causes/consequences and MSolutions
Only the red segments in
the Parking Assist
PARKTRONIC warning
displays are lit. You also
hear a warning tone for
approximately two sec-
onds.
Parking Assist
PARKTRONIC is then
deactivated and the indi-
cator lamp on the
PARKTRONIC button
lights up.Parking Assist PARKTRONIC has malfunctioned and has been deacti-
vated.
XIf problems persist, have Parking Assist PARKTRONIC checked at a
qualified specialist workshop.
Only the red segments in
the Parking Assist
PARKTRONIC warning
displays are lit. Parking
Assist PARKTRONIC is
then deactivated.The Parking Assist PARKTRONIC sensors are dirty or there is inter-
ference.
XClean the Parking Assist PARKTRONIC sensors (Ypage 262).
XSwitch the ignition back on.
The problem may be caused by an external source of radio or ultra-
sound waves.
XCheck to see if Parking Assist PARKTRONIC works at a different
location.
Parking Pilot
General notes
Parking Pilot is an electronic parking aid with
ultrasound. It measures the road on both sides
of the vehicle. A parking symbol indicates a suit-
able parking space. Active steering intervention
and brake application can assist you during
parking and when exiting a parking space. Park-
ing Assist PARKTRONIC is also available
(
Ypage 160).
Important safety notes
Parking Pilot is only an aid. It is not a replace-
ment for your attention to your immediate sur-
roundings. 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 Parking Assist PARKTRONIC is deactiva-
ted, Parking Pilot 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 Parking Pilot
parking procedure.
!If unavoidable, you should drive over obsta-
cles such as curbs slowly and not at a sharp
angle. Otherwise, you may damage the
wheels or tires.

Rif the camera lens is dirty or obstructed
Observe the notes on cleaning
(
Ypage 262)
Rif the rear of your vehicle is damaged. In this
case, have the camera position and setting
checked at a qualified specialist workshop
The field of vision and other functions of the rear
view camera may be restricted due to additional
accessories on the rear of the vehicle (e.g.
license plate holder, bicycle rack).
Activating/deactivating the rear view
camera
XTo activate: make sure that the SmartKey is
in position 2in the ignition lock.
XMake sure that the Activation by R gearfunction is selected in the multimedia system;
see the Digital Operator's Manual.
XEngage reverse gear.
The area behind the vehicle is shown with
guide lines in the multimedia system display.
The image from the rear view camera is avail-
able throughout the maneuvering process.
To deactivate: the rear view camera deacti-
vates if you shift the transmission to Por after
driving forwards a short distance.
Messages in the multimedia system dis- play
The rear view camera may show a distorted view
of obstacles, show them incorrectly or not at all.
The rear view camera does not show objects in
the following positions:
Rvery close to the rear bumper
Runder the rear bumper
Rin close range above the handle on the trunk
lid
!Objects not at ground level may appear to
be further away than they actually are, e.g.:
Rthe bumper of a parked vehicle
Rthe drawbar of a trailer
Rthe ball coupling of a trailer tow hitch
Rthe rear section of an HGV
