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
G
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.

i The last speed stored is cleared when you
switch off the engine. SPEEDTRONIC
General notes SPEEDTRONIC brakes automatically so that you
do not exceed the set speed. Change into a
lower gear in good time on long and steep down-
hill 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 overheating and wear-
ing too quickly.
Important safety notes If you fail to adapt your driving style, SPEED-
TRONIC can neither reduce the risk of an acci-
dent nor override the laws of physics. SPEED-
TRONIC cannot take into account road, weather or traffic conditions. SPEEDTRONIC is only an
aid. You are responsible for the distance to the
vehicle in front,f or vehicle speed, for braking in
good time, and for staying in lane.
If there is achange of drivers, advise the new
driver of the speed stored.
You can set avariable or permanent limit speed:
R variable for speed limits, e.g. in built-up areas
R permanent for long-term speed restrictions,
e.g. when driving with winter tyres fitted
(Y page 184)
i The speed indicated in the speedometer
may differ slightly from the limit speed stored. 182

If you depress the accelerator pedal beyond the
pressure point (kickdown), SPEEDTRONIC is
switched to passive mode. The SPEEDTRONIC SPEEDTRONIC
suspended
suspended message appears in the multifunc-
tion display.
You can then exceed the stored speed. SPEED-
TRONIC is activated again if you:
R drive slower than the stored speed without
kickdown
R set anew speed or
R call up the last speed stored again
The SPEEDTRONIC suspended SPEEDTRONIC suspended message in the
multifunction display disappears.
Deactivating variable SPEEDTRONIC
It is not possible to deactivate variable SPEED-
TRONIC by braking.
There are several ways to deactivate variable
SPEEDTRONIC:
X Briefly press the cruise control lever forwards

Cruise control or DISTRONIC PLUS is selec-
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

WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
R there is amalfunction in the system or in
the voltage supply.
R DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by avehi-
cle occupant or from outside the vehicle.
R the electrical system in the engine com-
partment,t he battery or the fuses have
been tampered with.
R the battery is disconnected.
R the accelerator pedal has been depressed,
e.g. by avehicle occupant.
There is arisk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
Further information on deactivating DISTRONIC PLUS (Y page 190).
If DISTRONIC PLUS detectst hat the vehicle in
front is stopping, it brakes your vehicle until it is stationary.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
i After
ashort period, the vehicle is secured
by the electric parking brake, thus relieving
the service brake.
i Depending on the specified minimum dis-
tance, your vehicle will come to astandstill at
as ufficient distance behind the vehicle in
front.T he specified minimum distance is set
using the control on the cruise control lever.
