WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect.Y ou will require considerably
more effort to steer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving.
Drive sensibly–s ave fuelObserve the following tips to save fuel:
X The tyres should always be inflated to the rec-
ommended tyre pressure.
X Remove unnecessary loads.
X Remove roof racks when they are not needed.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work carried out as
indicated by the service intervals in the Ser-
vice Booklet or by the service interval display.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic, on short jour- neys and in hilly terrain. ECO display
The ECO display shows you how economical
your driving style is. The ECO display assists you
in achieving the most economical driving style
for the selected settings and prevailing condi-
tions. Consumption can be significantly influ-
enced by your driving style. :

Driving tipsDriving and parking

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.
Have you rvehicl ewinterproofed at aqualified
specialist worksho patthe onset of winter. Driving tips

Stopping
G
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.
When DISTRONIC PLUS is activated, the trans-
mission is shifted automatically to position Pif:
R the driver's seat belt is not fastened and the
driver's door is open
R the engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function The electric parking brake secures the vehicle
automatically if DISTRONIC PLUS is activated
when the vehicle is stationary and:
R as ystem fault occurs
R the power supply is insufficient
If af ault occurs, the transmission may also shift
into position Pautomatically.
Setting aspeed X

The last stored speed increases or decreases in 10 km/h increments.
i If you accelerate to overtake, DISTRONIC
PLUS adjusts the vehicle's speed to the last
speed stored after you have finished overtak-
ing.
Setting the specified minimum distance You can set the specified minimum distance for
DISTRONIC PLUS by varying the time span
between one and two seconds. With this func-
tion, you can set the minimum distance that
DISTRONIC PLUS maintains to the vehicle in
front,d ependent on vehicle speed. You can see
this distance in the multifunction display
