Do not get into the vehicle again during the refu-
elling process. Otherwise, electrostatic charge
could build up again.
! Do not use diesel to refuel vehicles with a
petrol engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system.
Even small amounts of the wrong fuel can
result in damage to the fuel system and the
engine. Notify a qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
! Use a filter when adding fuel from a fuel can.
The fuel lines and/or the fuel injection system could otherwise be blocked by particles fromthe fuel can.
If you overfill the fuel tank, some fuel may spray
out when you remove the fuel pump nozzle.

Do not switch off the ignition while driving.
Drive sensibly – save fuel Observe the following tips to save fuel:
R The tyres should always be inflated to the rec-
ommended tyre pressure.
R Remove unnecessary loads.
R Warm up the engine at low engine speeds.
R Avoid frequent acceleration or braking.
R Observe the service intervals in the Service
Booklet or in the service interval display. Have all the maintenance work carried out in
accordance with Daimler AG regulations.
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

the multifunction display instead of range ?. In
addition, the 8warning lamp in the instru-
ment cluster lights up (Y page 249).The ECO display consists of three sections, with
an inner and outer area. The sections corre-

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.

sary acceleration and deceleration
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 a result of a particu-
larly economical driving style. Depending on the 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 a result of eco-
nomical driving. A higher level indicates a more
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 a fixed consumption reduction. 156
Driving tipsDriving and parking

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 factors are not included in the ECO dis-
play.
An economical driving style involves driving at a
moderate engine speed.
To achieve a higher value in the categories
"Acceleration" and "Constant":
R observe the gearshift recommendation
R drive the vehicle in drive program Cor E.
On long journeys at a constant 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 a journey. During
a prolonged driving time, these changes are
smaller. For more marked changes, perform a
manual reset (Y page 203).

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, the limiter or Distance Pilot DISTRONIC. 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 sys-
tem 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 the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
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 effectiveness.
To do this, brake more firmly from a higher
speed while paying attention to the traffic con-
ditions. 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 or
after driving through deep water.
You will have to depress the brake pedal more
firmly. Maintain a greater distance to the vehicle in front.
After driving on a wet road or having the vehicle
washed, brake firmly while paying attention to
the traffic conditions. This will warm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion. Driving tips
157Driving and parking Z

In a speed range from 0 - 60 km/h, Stop&Go
Pilot focuses on the vehicle in front, taking into
account lane markings, e.g. when following vehi-
cles in a traffic jam.
At speeds of more than 60 km/h, the Steering
Pilot focuses on detected lane markings (left
and right), only focusing on the vehicle in front if detected lane markings are not present at
speeds of up to 130 km/h.
If these conditions are not present, Steering
Pilot and Stop&Go Pilot cannot provide assis-
tance.
Distance Pilot DISTRONIC must be active in
order for the function to be available.
Important safety notes If you fail to adapt your driving style, Distance
Pilot DISTRONIC with Steering Pilot and
Stop&Go Pilot can neither reduce the risk of an
accident nor override the laws of physics. It can-
not take into account road, weather or traffic
conditions. Distance Pilot DISTRONIC with
Steering Pilot and Stop&Go Pilot is only an aid.
You are responsible for the distance to the vehi- cle in front, for vehicle speed, for braking in good
time and for staying in lane.
Distance Pilot DISTRONIC with Steering Pilot
and Stop&Go Pilot does not detect road and
traffic 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 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.
Distance Pilot DISTRONIC with Steering Pilot
and Stop&Go Pilot cannot continuously keep
your vehicle in the lane. In some cases, the
steering intervention is not sufficient to bring
the vehicle back to the lane. In such cases, youmust 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 insufficient
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, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R there are no lane markings, or several unclear
lane markings are present, e.g. around con-
struction sites
R the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
R the distance to the vehicle in front is too short
and thus the lane markings cannot be detec-
ted
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 longer assists you by performing steering interventions
if:
R you actively change lanes
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 Pilot and Stop&Go Pilot are auto-
matically active again.
Steering Pilot 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
on Distance Pilot DISTRONIC (Y page 162).
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 symbol
appears in the multifunction display. If you have Driving systems

the service brake. When the HOLD function 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

The electric parking brake secures the vehicle
automatically if the HOLD function is activated,
the vehicle is stationary and:
R a system fault occurs
R the power supply is insufficient
If a malfunction in the electric parking brake
occurs, then the transmission may also be shif-
ted into position P automatically. RACE START
Important safety notes i
RACE START must not be used on normal
roads. RACE START must only be activated
and used on dedicated road circuits, outside
of public road use.
i RACE START is only available in
Mercedes‑ AMG vehicles.
RACE START enables optimum acceleration
from a standing start. For this, a suitably high-
grip road surface is required, along with the
tyres and vehicle being in good condition. G
WARNING
If you use RACE START, individual tyres may
get into a spin and the vehicle could skid.
Depending on the selected ESP ®
mode, there
is an increased risk of skidding and having an accident. Make sure that no persons, animals
or obstacles are within range of the vehicle.

Detecting parking spaces Objects located above the height range of Active
Parking Assist will not be detected when the
parking space is measured. These are not taken
into account when the parking procedure is cal- culated, e.g. overhanging loads, tail sections or
loading ramps of goods vehicles. G
WARNING
If objects are located above the detection
range, Active Parking Assist may start to steer into the parking space too soon. As a result,
you could cause a collision. There is a risk of
an accident.
If objects are located above the detection
range, stop the vehicle and switch Active

Course-correcting brake application If Active Blind Spot Assist detects a risk of a side
impact in the monitoring range, a course-cor-
recting brake application is carried out. This is
designed to help you avoid a collision. G
WARNING
A course-correcting brake application cannot always prevent a collision. There is a risk of an
accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake appli-
cation. Always maintain a safe distance at the sides. If a course-correcting brake application occurs,

ing over a solid lane marking. There is a risk ofan accident.
An inappropriate brake application may be
interrupted at any time if you steer slightly in
the opposite direction. Always make sure that
there is sufficient distance to the side for
other traffic or obstacles. If you leave your lane under certain circumstan-
ces, the vehicle will brake briefly on one side.
This is intended to help you return the vehicle to
the original lane.
If a lane-correcting brake application occurs,
display :appears in the multifunction display.
A lane-correcting brake application can be made
after driving over a lane marking recognised as
being solid or broken. Before this, a warning
must have been issued by means of intermittent
vibration through the steering wheel. In addi-
tion, a lane with lane markings on both sides
must be detected.
In the case of a broken lane marking being
detected, a lane-correcting brake application
can only be made if a vehicle has been detected
in the adjacent lane. The following vehicles can have an influence on brake application: oncom- ing traffic, vehicles that are overtaking and vehi-
cles that are driving parallel to your vehicle.
i A further lane-correcting brake application
can only occur after your vehicle has returned
to the original lane.
No lane-correcting brake application occurs if: R you clearly and actively steer, brake or accel-
erate
