Upshifting (Mercedes-AMG vehicles) !
The automatic transmission does not shift
up automaticall yeven when the engine limit-
ing speed for the current gear is reached.
When the engine limiting speed is reached,
the fuel supply is cut to prevent the engine
from overrevving. Always make sure that the
engine speed does not reach the red area of
the rev counter. There is otherwise arisk of
engine damage. Before the engine speed reaches the red area,
an upshift indicator willbes hown in the multi-
function display.

Kickdown X
For maximu macceleration, depress the
accelerator pedalb eyond the pressure point.
The transmission shifts to alower gear
depending on the engine speed.
X Shift back up once the desired speed is
reached. During kickdown, you cannot shift gears using
the steering wheelg earshift paddles.
If you apply full throttle, the automatic trans-
missio nshifts up to the next gear when the
maximu mengine speed is reached .This pre-
vents the engine from overrevving.
Mercedes-AMG vehicles: kickdown is only
possible in the temporary setting. Automatic transmission

The ECO display consist
softhree sections, with
an inner and outer area. The section scorre-
spond to the following three categories: :
Acceleration
(evaluation of all accel-
eration processes):
R the outer area fills up and the inner
area lights up green: moderate
acceleration ,especially at higher
speeds.
R the outer area empties and the
inner area is grey: sporty acceler-
ation. ;
Coasting
(evaluation of all decelera-
tion processes):
R the outer area fills up and the inner
area lights up green: anticipatory
driving, keeping your distance and
early release of the accelerator.
The vehicle can coast without use
of the brakes.
R the outer area empties and the
inner area is grey: frequent heavy
braking. =
Constant
(continuous evaluation
over the entir ejourney):
R the outer area fills up and the inner
area lights up green: constant
speed and avoidance of unneces-
sary acceleration and decelera-
tion.
R the outer area empties and the
inner area is grey: fluctuations in
speed. The three inner areas display the current driving
style and light up green as aresult of aparticu-
larly economical driving style. Dependin gonthe
driving situation, up to two areas may light up
simultaneously.
At the beginning of the journey, the three outer
areas are empty and fill up as aresult of eco-
nomical driving. Ahigher level indicates amore
economical driving style. If the three outer areas
are completely filled at the same time, the driver
has adopted the most economical driving style
for the selected settings and prevailing condi-
tions. The ECO display border lights up.
The ECO display does not indicate the actual fuel consumption. The additionally achieved range displayed under
Bonus fr. start Bonus fr. start does not
indicate afixed consumption reduction.
In addition to driving style, the actual consump- tion is affected by other factors, such as:
R load
R tyre pressure
R cold start
R choice of route
R the use of electrical consumers
These factor sare not included in the ECO dis-
play.
An economical driving style involves driving at a
moderate engine speed.
To achieve ahigher value in the categories
"Acceleration" and "Constant":
R observe the gearshift recommendation
R drive the vehicle in drive program E(vehicles
with DYNAMIC SELECT switch)
On long journeys at aconstant speed, e.g. on the
motorway, only the outer area for "Constant"
will change.
The ECO display summarises the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer areas at the start of ajourney. During
ap rolonged driving time, these changes are
smaller. For more marked changes, perform a
manual reset (Y page 238).

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

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-
tion swhen temperatures are around freezing

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
If there is achange of drivers, advise the new
driver of the speed stored.

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
