High-performance and ceramic brakes
(Mercedes-AMG vehicles) The AMG brake systems are designed for heavy
loads. This may lea dtonoise when braking. This
is dependent on:
R speed
R braking force
R environmental conditions, such as tempera-
ture and humidity
The wea rofindividua lbrake system compo-
nents such as the brake pads/linings or brake
discs depends on individuald riving style and
operating conditions.
For this reason, it is impossible to state amile-
age (service life )that wil lbevalidu nder all cir-
cumstances. An aggressive driving style will
lea dtoh igh wear. You can obtai nmore infor-
mation on this from aqualified specialist work-
shop.
Brake pads/linings and discs that are either new or have been replaced only achieve optimum
braking effect after severa lhundre dkilometres
of driving. Compensate for the reduced braking
effect by applying greater force to the brake
pedal. Always be aware of this and adapt your
driving and braking accordingly during the run-
ning-in period.
Excessive heavy braking results in correspond-
ingly high brake wear. Observe the brake wear
warning lamp in the instrument cluste rand note
any brake status messages in the multifunction
display .Ifyou regularl ydrive at high speeds, it is
particularly important to have the brake system
checked and maintained regularly. Driving on wetr
oads
Aquaplaning If wate
rhas accumulated to acertain depth on
the road surface, there is adange rofa quaplan-
ing occurring, even if:
R you are driving at low speeds
R the tyres have adequate tread depth
For this reason, drive in the following manner in
the event of heavy rain or in conditions in which aquaplaning can occur:
R lower you rspeed
R avoi dtyre ruts R
avoi dsudden steering movements
R brake carefully
Driving on flooded roads !
Bear in mind that vehicles travelling in front
or in the opposite direction create waves. This may caus ethe maximu mpermissible water
depth to be exceeded.
These notes must be observed under all cir-
cumstances. You coul dotherwise damage
the engine, the electronics or the transmis-
sion.
If you must drive on stretches of road on which
wate rhas collected, please bea rinmind that:
R in the case of standing water, the wate rlevel
must be no higher than the lower edge of the vehicl ebody
R you should drive no faster than walking pace Winter driving

WARNING
If you shift downonas lippery road surface in
an attempt to increas ethe engine's braking
effect, the drive wheels coul dlose their grip.
This increases the risk of skidding and having
an accident.
Do not shift dow nfor additiona lengine brak-
ing on aslippery road surface. G
DANGER
If the exhaust pipeisb locked or adequate
ventilation is not possible,p oisonous gases
such as carbon monoxide (CO )may enter the
vehicle. This is the case, e.g. if the vehicle
become strappe dinsnow. There is arisk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipea nd area
around the vehicl eare clea rofsnow. To
ensure an adequate supply of fresh air, open a windo wont he side of the vehicl ethat is not
facing into the wind.
Have you rvehicl ewinterproofed at aqualified
specialist worksho patthe onset of winter. Driving tips
179Driving and parking Z

You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden acceleration,
steerin gand braking manoeuvres .Donot use
cruis econtrol or DISTRONIC PLUS.
If the vehicle threaten stoskid or cannot be
stopped when movin gatlow speed:
X Vehicles with manual transmission: shift
to neutral.
X Vehicles with automatic transmission:
shift the transmission to position
N.
X Try to brin gthe vehicle under control by using
correctiv esteering.
The outsid etemperature indicator is not
designed to serv easanice-warnin gdevic eand
is therefore unsuitable for that purpose.
Changes in the outsid etemperature are dis-
played afte rashortdelay.
Indicated temperatures just above the freezing
point do not guarantee that the road surfac eis
free of ice. The road may still be icy, especially in wooded areas or on bridges .The vehicle could
skid if you fail to adapt your drivin gstyle. Always
adapt your drivin gstyle and drive at aspeed to
suit the prevailin gweather conditions.
You should pay special attention to road condi-

Genera lnotes Cruise control maintains
aconstan troad speed
for you. It brakes automatically in order to avoid
exceeding the set speed. Change int oalower
gear in good tim eonlong and steep downhill
gradients. Take particular not eofthis when driv-
ing aladen vehicle and when towin gatrailer. By
doing so, you will make use of the braking effect
of the engine. This relieve sthe load on the brake
syste mand prevent sthe brakes from overheat-
ing and wearing too quickly.
Use cruis econtrol only if road and traffic con-
dition sare appropriate for maintainin gasteady
speed for aprolonged period. You can store any
road speed above 30 km/h.
Important safet ynotes If you fail to adapt your drivin
gstyle, cruis econ-
trol can neither reduce the risk of an accident
nor override the laws of physics .Cruise control
cannot tak eintoa ccount road, weather or traffic
conditions. Cruise control 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 stayin ginlane.
Do not use cruis econtrol:
R in road and traffic condition swhich do not
allow you to maintain aconstan tspeed, e.g. in
heavy traffic or on windin groads
R on smoot horslippery roads. Braking or accel-
erating can cause the drive wheels to lose
traction and the vehicle could the nskid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow

ted.
i The last speed stored is cleared when you
switch off the engine.
Permanent SPEEDTRONIC
You can use the on-board computer to limit the
speed permanently to avalue between
160 km/h(e.g. for driving on winter tyres) and
the maximum speed (Y page 248).
Shortly before the stored speed is reached, it
appears in the multifunction display.
Permanent SPEEDTRONIC remains active, even
if variable SPEEDTRONIC is deactivated.
You cannot exceed the stored limit speed, even if you depress the accelerator pedal beyond the
pressure point (kickdown). DISTRONIC PLUS
General notes DISTRONIC PLUS regulates the speed and auto-
matically helps you maintain the distance to the
vehicle detected in front.V ehicles are detected
with the aid of the radar sensor system.
DISTRONIC PLUS brakes automatically so that
the set speed is not exceeded.
Change into alower gear in good time on long
and steep downhill gradients. Take particular
note of this when driving aladen vehicle. By
doing so, you will make use of the braking effect
of the engine. This relieves the load on the brake
system and preventst he brakes from overheat-
ing and wearing too quickly.
If DISTRONIC PLUS detectst hat there isarisk of
ac ollision, you will be warned visuallya nd
acoustically. Without your intervention,
DISTRONIC PLUS cannot prevent acollision. An
intermittent warning tone will then sound and
the distance warning lamp will light up in the
instrumen tcluster. Brake immediately to
increase the distance to the vehicle driving in
front,ort ake evasive action, provided it is safe
to do so.
DISTRONIC PLUS operates in the range
between 0km/h and 200 km/h.
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
Important safety notes G
WARNING
DISTRONIC PLUS does not react to:
R people or animals
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncominga nd crossing traffic
As aresult, DISTRONIC PLUS may neither give
warnings nor interveneins uch situations.
There is arisk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. G
WARNING
DISTRONIC PLUS cannot always clearly rec-
ognise other road users and complex traffic
conditions. 184
Driving systemsDriving and parking

In such cases, DISTRONIC PLUS may:
R give an unnecessary warning and then
brake the vehicle
R neither give awarning nor intervene
R accelerate or brake unexpectedly
There is arisk of an accident.
Continue to drive carefully and be prepared to
brake, particularly if DISTRONIC PLUS warns
you. G
WARNING
DISTRONIC PLUS brakes yourv ehicle with up
to 50% of the maximum possible deceleration.
If this deceleration is not sufficient,
DISTRONIC PLUS alerts you with avisuala nd
acoustic warning. There is arisk of an acci-
dent.
Apply the brakes yourself in these situations
and try to take evasive action.
! When DISTRONIC PLUS or the HOLD func-
tion is activated, the vehicle brakes automat- icallyinc ertain situations.
To avoid damage to the vehicle ,deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations:
R when towing away
R in ac ar wash
If you fail to adapt yourd riving style, DISTRONIC
PLUS can neither reduce the risk of an accident
nor override the lawsofp hysics. DISTRONIC
PLUS cannot take road and weather conditions
or traffic conditions into account. DISTRONIC
PLUS is only an aid.Y ou are responsible for the
distance to the vehicle in front, for vehicle
speed,f or braking in good time, and for staying
in lane.
Do not use DISTRONIC PLUS:
R in road and traffic conditions which do not
allow you to maintain aconstant speed,e .g. in
heavy traffic or on winding roads
R on smooth or slippery roads. Braking or accel-
erating can cause the drive wheelstol ose
traction and the vehicle could then skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow DISTRONIC PLUS may not detect narrow vehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on
adifferent line.
In particular, the detection of obstacle scan be
impaired in the case of:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radars ources
R the possibility of strong radarr eflections, for
example ,inmulti-storey car parks
If DISTRONIC PLUS no longer detects avehicle
in front, it may unexpectedly accelerate to the
speed stored.
This speed can:
R be too high for afilter lane or aslip road
R be so high in the right lane that you pass vehi-
cles driving on the left (left-hand drive coun-
tries)
R be so high in the left lane that you pass vehi-
cles driving on the right (right-hand drive
countries)
If there is achange of drivers, advise the new
driver of the speed stored.

Driving systemsDriving and parking

If there is no vehicle in front, DISTRONIC PLUS
operates in the same way as cruise control.
If DISTRONIC PLUS detects that the vehicle in
front has slowed down, it brakes yourv ehicle.In
this way,t he distance you have selected is main-
tained.
If DISTRONIC PLUS detects afaster-moving
vehicle in front, it increases the driving speed.
However, the vehicle is only accelerated up to
the speed you have stored.
Selecting the drive program DISTRONIC PLUS supports asporty driving style
when you have selected the Sor S+ drive pro-

vehicle in front or to the set speed is then notice- ablym ore dynamic. If you have selected the Cor
E drive program, the vehicle accelerates more
gently. This setting is recommended in stop-
start traffic.
Changing lanes
If you change to the overtaking lane, DISTRONIC
PLUS supports you if:
R you are driving faster than 70 km/h
R you switch on the respective turn signal
R DISTRONIC PLUS does not detect adanger of
collision
If these conditions are met, yourv ehicle is accel-
erated. Acceleration willbei nterrupted if chang-
ing lanes takes too long or if the distance
betwee nyourv ehicle and the vehicle in front
becomes too small.
i Vehicles with COMAND Online:
when you
change lanes, DISTRONIC PLUS monitors the right lane in the case of left-side traffic or the
left lane in the case of right-side traffic.
Vehicles with Audio 20: when you change
lanes, DISTRONIC PLUS monitors the left lane
on left-hand-drive vehicle sorthe right lane on
right-hand-drive vehicles. Road and traffic conditions i
The following function is only available in

tries.
DISTRONIC PLUS uses additional information
from yourn avigation system so that it can adapt
to certain traffic situations. This is the case if,
whilef ollowing avehicle,D ISTRONIC PLUS is
active and you:
R approach or drive around aroundabout
R approach aT-junction
R turn off at amotorway exit
R approach atollgate
Even if the vehicle in front leaves the detection
range, DISTRONIC PLUS temporaril ymaintains
the current driving speed and does not acceler- ate. This is basedont he current map data in the
navigation system.
Afterwards, the vehicle accelerates back to the
speed you set.
The system takes into account the fact that
overtaking on the right is not permitted on
motorway sorhigh-speed major roads at speeds
above 80 km/h. The driving speed is adjusted to the speed of the queueofv ehiclesinthe adja-
cent lane to the left.
i Prevention of overtaking on the right applies
to countries where traffic drives on the right.
In countries where traffic drives on the left,
overtaking on the left is prevented accord-
ingly. Driving systems
