Driving safety systems
Driving safety systems overview
In this section, you will find information about
the following driving safety systems:
R ABS (Anti-lock BrakingSystem)
(Y page 68)
R BAS (Brake AssistSystem) (Y page 69)
R Active Brake Assist (Y page 69)
R Adaptive brake lights (Y page 71)
R ESP ®
(E lectronic StabilityProgram)
(Y page 72)
R EBD (electronic brake forcedistribution)
(Y page 75)
R ADAPTIVE BRAKE (Y page 75)
R STEER CONTROL (Y page 75)Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of an accident nor override
the laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for maintaining the distance to the
vehicle in front, for vehicle speed, for braking in
good time, and for staying in lane. Always adapt your driving style to suit the prevailing road and weather conditions and maintain a safe distance
from the vehicle in front. Drive carefully.
The driving safety systems described work as
effectively as possible only when there is ade-
quate contact between the tyres and the road
surface. Please pay special attention to the
notes on tyres, recommended minimum tyre
tread depths etc. (Y page 335).
In wintry driving conditions, always use winter
tyres (M+S tyres) and, if necessary, snow
chains. Only in this way will the driving safety
systems described in this section work as effec-
tively 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 on 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 8 km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you
brake only gently.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 68). G
WARNING
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.
If ABS is malfunctioning, other systems, includ-
ing driving safety systems, will also become
inoperative. Observe the information on the ABS warning lamp (Y page 267) and display mes-
sages that may be shown on the instrument
cluster (Y page 235).
Brakes X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To 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; this serves as a
reminder to take extra care while driving.
Off-road ABS An ABS system specifically suited to off-road
terrain is activated automatically once the off-
road program is activated (Y
page 192).
At speeds below 30 km/h, the front wheels lock
cyclically during braking. The digging-in effect
achieved in the process reduces the stopping 68

Tips for driving with Distance Pilot
DISTRONIC General notes
Pay particular attention in the following traffic
situations:
R Cornering, entering and exiting a bend: the
ability of Distance Pilot DISTRONIC to detect
vehicles when cornering is limited. Your vehi-
cle may brake unexpectedly or late.
R Driving on a different line: Distance Pilot
DISTRONIC may not detect vehicles driving in
a different lane. The distance to the vehicle in front will be too short.
R Other vehicles changing lane: Distance Pilot
DISTRONIC has not detected the vehicle cut-
ting in yet. The distance to this vehicle will be
too short.
R Narrow vehicles: Distance Pilot DISTRONIC
does not detect the vehicle in front on the
edge of the carriageway because of its narrow
width. The distance to the vehicle in front will
be too short.
R Obstacles 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 revealed, Distance Pilot DISTRONIC will not brake for them.
R Distance Pilot DISTRONIC may mistakenly
detect vehicles that are crossing your lane. If
you activate Distance Pilot DISTRONIC under the following conditions, the vehicle could
pull away unintentionally:
- at traffic lights with crossing traffic, for
example
- if there is a vehicle in front after a crossing
with the HOLD function activated
In such situations, brake if necessary. Distance Pilot DISTRONIC is then switched off. HOLD function
General notes The HOLD function can assist the driver in the
following situations:
R when pulling away, especially on steep slopes
R when manoeuvring on steep slopes
R when waiting in traffic The vehicle is kept stationary without the driver
having to depress the brake pedal.
The braking effect is cancelled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
Important safety notes G
WARNING
When leaving the vehicle, it can still roll away despite being braked by the HOLD function if:
R there is a malfunction in the system or in
the voltage supply
R the HOLD function is deactivated by the
accelerator pedal being depressed, e.g. by
a vehicle occupant
R the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with
R the battery is disconnected
There is a risk of an accident.
Before leaving the vehicle, always deactivate
the HOLD function and secure the vehicle
from rolling away.
! When Distance Pilot DISTRONIC or the
HOLD function is activated, the vehicle
brakes automatically in certain situations.
To avoid damage to the vehicle, deactivate
Distance Pilot DISTRONIC and the HOLD
function in the following or similar situations:
R when towing away
R in a car wash
Deactivating the HOLD function (Y page 187).
Activation conditions You can activate the HOLD function if:
R
the vehicle is stationary
R the engine is running or if it has been auto-
matically switched off by the ECO start/stop
function
R the driver's door is closed or if your seat belt
is fastened
R the electric parking brake is released
R Distance Pilot DISTRONIC is deactivated
R the transmission is in position h,kori
on vehicles with automatic transmission 186

The
AMG Ride Control COMFORT
AMG Ride Control COMFORT message
appears in the multifunction display. 4MATIC
! Never tow the vehicle with one axle raised.
This may damage the differential. Damage of
this sort is not covered by the Mercedes-Benz
implied warranty. All wheels must remain
either on the ground or be fully raised.
Observe the instructions for towing the vehi-
cle with all wheels in full contact with the
ground.
4MATIC, together with ESP ®
, improves the trac-
tion of your vehicle whenever a drive wheel
spins due to insufficient grip.
If you fail to adapt your driving style, 4MATIC can neither reduce the risk of an accident nor over-
ride the laws of physics. 4MATIC cannot take
account of road, weather and traffic conditions.
4MATIC is only an aid. You are responsible for
the distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
lane.
If a drive wheel spins due to insufficient grip:
R when pulling away, only depress the acceler-
ator pedal as far as is necessary.
R accelerate less when driving.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if you
use winter tyres (M+S tyres), with snow
chains if necessary. DSR
General notes i
DSR (Downhill Speed Regulation) is only
available for vehicles with the ON&OFFROAD
package.
DSR is an aid to assist you when driving down-
hill. It keeps the speed of travel at the speed
selected on the on-board computer. The steeper
the downhill gradient, the greater the DSR brak-
ing effect on the vehicle. When driving on flat
stretches of road or on an uphill gradient, the
DSR braking effect is minimal or non-existent.
DSR controls the vehicle’s speed when it is acti- vated and the transmission is in position h,k
or i. By accelerating or braking, you can always drive at a higher or a lower speed than
that set on the on-board computer.
Important safety notes G
WARNING
If the speed driven and the set speed deviate and you activate DSR on a slippery road sur-
face, the wheels may lose traction. This
increases the risk of skidding and having an
accident.
Before switching DSR on, please take into
consideration the road surface and the differ-
ence between driving speed and the set
speed.
If you fail to adapt your driving style, DSR can
neither reduce the risk of accident nor override the laws of physics. DSR cannot take account ofroad, weather and traffic conditions. DSR is only
an aid. You are responsible for the distance to
the vehicle in front, for vehicle speed, for brak-
ing in good time and for staying in lane.
You are always responsible for keeping control
of the vehicle and for assessing whether the
downhill gradient can be managed. DSR may not
always be able to keep to the set speed, depend-
ing on road surface and tyre conditions. Select a set speed suitable for the prevailing conditions
and when necessary, apply the brakes manually.
Further information about "Driving off-road"
(Y page 173).
Activating/deactivating DSR If you activate DSR and no speed has been set,
the vehicle decelerates to 6 km/h.
You can only activate DSR when driving at
speeds below 30 km/h.190
Driving systemsDriving and parking

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
(Y page 193).
i The active braking application is only avail-
able on vehicles with automatic transmission.
Important safety notes Parking Pilot is only an aid. It is not a substitute
for your attention to the immediate surround-
ings. The responsibility for safe manoeuvring
and parking remains with you. Make sure that no
persons, animals or objects are in the manoeu-
vring range.
When Parking Assist PARKTRONIC is deactiva-
ted, Parking Pilot is also unavailable. G
WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
cause you to collide with other road users.
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 kerbs slowly and not at a sharp
angle. Otherwise, you may damage the
wheels or tyres.
Parking Pilot may also display spaces not suita- ble for parking, e.g.:
R in a zone where parking or stopping is pro-
hibited
R in front of driveways or entrances and exits
R on unsuitable surfaces
Parking tips:
R on narrow roads, drive as closely as possible
past the parking space
R parking spaces that are littered or overgrown
might be identified or measured incorrectly R
parking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly
R snowfall or heavy rain may lead to a parking
space being measured inaccurately
R pay attention to the Parking Assist
PARKTRONIC warning messages
(Y page 194) during the parking procedure
R you can intervene in the steering procedure to
correct it at any time. Parking Pilot will then be cancelled
R when transporting a load that protrudes from
your vehicle, you should not use Parking Pilot
R never use Parking Pilot when snow chains are
fitted
R make sure that the tyre pressures are always
correct. This has a direct influence on the
parking characteristics of the vehicle
Use Parking Pilot for parking spaces that are:
R parallel or at right angles to the direction of
travel
R on straight roads, not bends
R on the same level as the road, e.g. not on the
pavement
For vehicles with the trailer tow hitch folded out,
the minimum length for parking spaces is
slightly longer.
If you have attached a trailer to your vehicle, you
should not use Parking Pilot. Once the electrical connection is established between your vehicle
and the trailer, Parking Pilot is no longer availa-
ble. Parking Assist PARKTRONIC is deactivated
for the rear area.
Detecting parking spaces Objects located above the detection range of
Parking Pilot will not be detected when the park-
ing space is measured. These are not taken into
account when the parking procedure is calcula- ted, e.g. overhanging loads, tail sections or load-
ing ramps of goods vehicles. Parking Pilot may
therefore guide you into the parking space too
early.
Parking Pilot does not assist you parking in
spaces at right angles to the direction of travel if:
R two parking spaces are located directly next
to one another
R the parking space is directly next to a low
obstacle such as a low kerb
R you forward-park 196

Information in the Digital Owner's Man-
ual In the Digital Owner's Manual, you will find infor-
mation on the following topics:
R Displays in the COMAND display
R Images displayed with PARKTRONIC display
Stopping the 360° camera display As soon as your vehicle exceeds a speed of
30 km/h with the function activated, the func-
tion switches off. The previous display appears
on the COMAND display. You can also switch
the display by selecting the &symbol in the
display and pressing Wthe COMAND controller
to confirm. ATTENTION ASSIST
General notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 60 km/h to
200 km/h speed range. If ATTENTION ASSIST
detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes ATTENTION ASSIST is only an aid. It may not
always detect fatigue or lapses in concentration
until too late, or may not detect 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 in the following situations:
R the length of the journey is less than approx-
imately 30 minutes
R if the road condition is poor, e.g. if the surface
is uneven or contains potholes
R in the event of strong crosswinds
R if you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
R if you are predominantly driving at a speed
below 60 km/h or above 200 km/h R
if the time has been set incorrectly
R in active driving situations, such as when you
change lanes or change your speed
ATTENTION ASSIST is reset and starts assessing
your tiredness again when you continue your
journey if:
R you switch off the engine
R you take off your seat belt and open the driv-
er'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 (Y
page 226) of
the on-board computer.
X Select the assistance graphics display for
ATTENTION ASSIST using the on-board com-
puter (Y page 226).
The following information is displayed:
R the length of the journey since the last break
R the attention level determined by ATTENTION
ASSIST( Attention level Attention level), displayed in a
bar display in five levels from high to low.
R if ATTENTION ASSIST is unable to calculate
the attention level and cannot output a warn-
ing, the System suspended System suspended message
appears. The bar display then changes the
display, e.g. if you are driving at a speed below 60 km/h or above 200 km/h.
