Brakes
Important safety notes G
WARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients Change into a lower gear in good time on long
and steep downhill gradients. Take particular note of this when driving a laden vehicle.
This also applies if you have activated cruise
control, SPEEDTRONIC or DISTRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to maintain
vehicle speed. This relieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly.
Heavy and light loads G
WARNING
The braking system can overheat if you leave your foot on the brake pedal while driving.
This increases the braking distance and could
even cause the braking system to fail. There is
a risk of an accident.
Never use the brake pedal as a footrest. Do
not simultaneously depress both the brake
pedal and the accelerator pedal while driving.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If heavy demands are made on the brakes, do not park the vehicle immediately. Drive on for
a short while. This allows the airflow to cool
the brakes more quickly.
If the brakes have been used only moderately,
you should occasionally test their effective- ness. To do this, brake more firmly from a
higher speed while paying attention to the
traffic conditions. This improves the grip of
the brakes.
Wet road surfaces If you have driven for a long time in heavy rain
without braking, there may be a delayed reac-
tion from the brakes when braking for the first time. This may also occur after a car wash orafter driving through deep water.
You will have to depress the brake pedal more
firmly. Maintain a greater distance to the vehi-
cle in front.
After driving on a wet road or having the vehi- cle washed, brake firmly while paying atten-
tion to the traffic conditions. This will warm upthe brake discs, thereby drying them more
quickly and protecting them against corro-
sion.
Limited braking performance on salt-
treated roads If you drive on salt-treated roads, a layer of
salt may form on the brake discs and pads.
This can increase the braking distance con-
siderably.
R In order to prevent any salt build-up, apply
the brakes occasionally while paying atten-
tion to the traffic conditions.
R Carefully depress the brake pedal at the
end of the journey and when starting the
next journey.
R Maintain a much greater distance to the
vehicle in front.
New brake discs and brake pads/
linings Brake pads/linings and discs that are either
new or have been replaced only achieve opti- mum braking effect after several hundred kil-
ometres of driving. Compensate for the
reduced braking effect by applying greater
force to the brake pedal. 186
Driving tipsDriving an
d parking

For safety reasons, Mercedes-Benz recom-
mends only fitting the following brake discs
and brake pads/linings:
R brake discs that have been approved by
Mercedes-Benz
R brake pads/linings that have been
approved by Mercedes-Benz or that are of
an equivalent standard of quality
Other brake discs or brake pads/linings can
compromise the safety of your vehicle.
Always replace all brake discs and brake
pads/linings on an axle at the same time.
Always fit new brake pads/linings when
replacing brake discs.
The vehicle is equipped with lightweight
brake discs to which the wheel assembly with
rim and threaded connection is matched.
The use of brake discs other than those
approved by Mercedes-Benz may alter track
width and is subject to approval, if applicable.
Shock-type loads when handling the brake
discs, such as when changing wheels, can
lead to a reduction in comfort when driving
with lightweight brake discs. Avoid shock-
type loads on the lightweight brake discs,
particularly on the brake plate.
AMG high-performance and ceramic
brakes The high-performance brake system is only
available on Mercedes-AMG vehicles.
The AMG brake systems are designed for
heavy loads. This may lead to noise when
braking. This is dependent on:
R speed
R braking force
R environmental conditions, such as temper-
ature and humidity
The wear of individual brake system compo-
nents such as the brake pads/linings or brake discs depends on individual driving style and
operating conditions.
For this reason, it is impossible to state a
mileage (service life) that will be valid under all circumstances. An aggressive driving style
will lead to high wear. You can obtain further information about this from your Mercedes-
Benz Service Centre.
Brake pads/linings and discs that are either
new or have been replaced only achieve opti- mum braking effect after several hundred kil-
ometres 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 running-in period.
Excessive heavy braking results in corre-
spondingly high brake wear. Observe the
brake wear warning lamp in the instrument
cluster and note any brake status messages
in the multifunction display. If you regularly
drive at high speeds, it is particularly impor-
tant to have the brake system checked and
maintained regularly. Driving on wet roads
Aquaplaning If water has accumulated to a certain depth
on the road surface, there is a danger of aqua-
planing 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 your speed
R avoid tyre ruts
R avoid sudden 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 cause the maximum per-
missible water depth to be exceeded.
These notes must be observed under all
circumstances. You could otherwise dam- Driving tips

age the engine, the electronics or the trans-
mission.
If you must drive on stretches of road on
which water has collected, please bear in
mind that:
R in the case of standing water, the water
level must be no higher than the lower edge
of the vehicle body
R you should drive no faster than walking
pace Winter driving
G
WARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winterproofed at a qualified specialist workshop at the onset of winter.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres. Do
not use cruise control or DISTRONIC PLUS. If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Shift the transmission to position N.
X Try to bring the vehicle under control by
using corrective steering.
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.

Cruise control
General notes Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. Change into
a lower gear in good time on long and steep
downhill gradients. Take particular note of
this when driving a laden vehicle. By doing so, you will make use of the braking effect of the engine. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly.
Use cruise control only if road and traffic con-
ditions are appropriate for maintaining a
steady speed for a prolonged period. You can store any road speed above 30 km/h.
Important safety notes If you fail to adapt your driving style, cruise
control can neither reduce the risk of an acci-
dent nor override the laws of physics. Cruise
control cannot take into account road,
weather or traffic conditions. Cruise control is
only an aid. You are responsible for the dis-
tance to the vehicle in front, for vehicle speed, for braking in good time and for staying in
lane.
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintain a constant speed, e.g.
in heavy traffic or on winding roads
R on smooth or slippery roads. Braking or
accelerating can cause the drive wheels to lose traction and the vehicle could then
skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow

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 oncoming and crossing traffic
As a result, DISTRONIC PLUS may neither give
warnings nor intervene in such situations.
There is a risk 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.
In such cases, DISTRONIC PLUS may:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor intervene
R accelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be prepared to
brake, particularly if DISTRONIC PLUS warns
you. G
WARNING
DISTRONIC PLUS brakes your vehicle with up to 50 %of the maximum possible deceleration.
If this deceleration is not sufficient,
DISTRONIC PLUS alerts you with a visual and
acoustic warning. There is a risk of an acci-
dent.
Apply the brakes yourself in these situations
and try to take evasive action.
! When DISTRONIC PLUS or the HOLD
function is activated, the vehicle brakes
automatically in certain 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 a car wash
If you fail to adapt your driving style,
DISTRONIC PLUS can neither reduce the risk
of an accident nor override the laws of phys-
ics. DISTRONIC PLUS cannot take road and
weather conditions or traffic conditions into
account. DISTRONIC PLUS 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.
Do not use DISTRONIC PLUS:
R in road and traffic conditions which do not
allow you to maintain a constant speed, e.g.
in heavy traffic or on winding roads
R on smooth or slippery roads. Braking or
accelerating can cause the drive wheels to lose 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
vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line.
In particular, the detection of obstacles can
be impaired in the case of:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R the possibility of strong radar reflections,
for example, in multi-storey car parks
If DISTRONIC PLUS no longer detects a vehi-
cle in front, it may unexpectedly accelerate to the speed stored. Driving systems

(left and right), only focusing on the vehicle in
front if detected lane markings are not pres-
ent.
If these conditions are not present, Steering
Assist and Stop&Go Pilot cannot provide
assistance.
DISTRONIC PLUS must be active in order for
the function to be available.
Important safety notes
If you fail to adapt your driving style,
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot can neither reduce the risk of
an accident nor override the laws of physics. It cannot take into account road, weather or
traffic conditions. DISTRONIC PLUS with
Steering Assist and Stop&Go Pilot 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.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot does not detect road and traf-
fic conditions and does not detect all road
users. If you are following a vehicle which is
driving towards the edge of the carriageway,
your vehicle could come into contact with the
kerb or other road boundaries. Be particularly
aware of other road users, e.g. cyclists, that
are directly next to your vehicle.
Obstacles such as traffic pylons on the lane or projecting out into the lane are not detected.
An inappropriate steering intervention, e.g.
after intentionally driving over a lane marking,
can be corrected at any time if you steer
slightly in the opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot cannot continuously keep your vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehi-
cle back to the lane. In such cases, you must steer the vehicle yourself to ensure that it
does not leave the lane. The support offered by the system may be
impaired if:
R there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray
R there is glare, e.g. from oncoming traffic,
the sun or reflection from other vehicles
(e.g. if the road surface is wet)
R the windscreen is dirty, misted up, dam-
aged or covered, for instance by a sticker,
in the vicinity of the camera
R no or several, unclear lane markings are
present for one lane, e.g. in a construction
area
R the lane markings are worn away, dark or
covered up, e.g. by dirt or snow
R the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
R the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
R the road is narrow and winding
R there are highly variable shade conditions
on the road
The system is switched to passive and no lon-
ger assists you by performing steering inter-
ventions if:
R you actively change lane
R you switch on the turn signal
R you take your hands off the steering wheel
or do not steer for a prolonged period of
time
i After you have finished changing lanes,
Steering Assist and Stop&Go Pilot are auto-
matically active again.
Steering Assist and Stop&Go Pilot cannot
provide assistance:
R on very sharp corners
R a loss of tyre pressure or a defective tyre
has been detected and displayed
Pay attention also to the important safety
notes for DISTRONIC PLUS (Y page 195).204
Driving systemsDriving and parking

The steering interventions are carried out
with a limited steering moment. The system
requires the driver to keep his hands on the
steering wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you
with a visual warning. A steering wheel sym-
bol appears in the multifunction display. If you have still not started to steer and have not
taken hold of the steering wheel after five
seconds at the latest, a warning tone also
sounds to remind you to take control of the
vehicle. Steering Assist and Stop&Go Pilot
switch to passive mode. DISTRONIC PLUS
