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 steerin gand the brake boostin
geffect. You will require considerably
more effort to steer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving. ECO display
ECO display (example)
The ECO display gives you information on how
economical your driving style is. The ECO dis-
play assists you in achieving the optimum
driving style in term
sofconsumption ,taking
the actual and selected conditions into con-
sideration. Your driving style can significantly
influenc ethe vehicle's consumption.
The ECO display consists of three bars:
R Acceleration
R Constant
R Coasting
The percen tvalue is th eaverage value of the
three bars .The three bars and the average
value commence with avalue of 50%. Ahigher
percentage indicates amoree conomical driv-
ing style.
The ECO display provides no information on
the actual fue lconsumption. Afixed percent-
age value of the ECO display does not corre-
spon dtoaf ixed consumption figure in
l/100km.
Apar tfromd rivin gstyle, consumption is
dependent on many factors such as:
R load
R tyre pressure
R cold start
R selected route
R number of consumer sthat are switched on Driving tips

i
This also applies if you have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to prevent the
vehicle from gaining speed. This relieves the
load on the brake system and prevent sthe
brakes from overheatin gand 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 distanc eand could
even cause the braking system to fail. There
is ar isk of an accident.
Never use the brake pedal as afootrest. Do
not simultaneously depress both the brake
pedal and the accelerator pedal while driving.
! Depressin gthe brake pedal constantly
results in excessiv eand premature wear to
the brake pads.
If the brakes have been subjected to aheavy
load, do not stop the vehicle immediately, but
drive on for ashort while. This allows the air-
flow 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. This improves the grip of the
brakes.
Wet road surfaces If you have driven for
along time in heavy rain
without braking, there may be adelayedr eac-
tion from the brakes when braking for the first
time. This may also occur after the vehicle has
been washed or driven through deep water.
You have to depress the brake pedal more
firmly. Maintain agreater distanc efrom the
vehicle in front.
After driving on awet road or having the vehi-
cle washed, brake firmly while paying atten- tion to the traffic conditions. This will warm
up the brake discs, thereby drying them more
quickly and protecting them against corro-
sion.
Limited braking performance on salt-
treated roads
If you drive on salted roads,
alayer of salt
residue may form on the brake discs and
brake pads. This can result in asignificantly
longer braking distance.
R Brake occasionally to remove any possible
salt residue. Make sure that you do not
endanger other road users when doing so.
R Carefully depress the brake pedal and the
beginnin gand end of ajourney.
R Maintain agreater distance to the vehicle
ahead.
New brake pads/linings New and replaced brake pads and discs only
reach their optimum braking effect after sev-
eral hundred kilometres of driving. Compen-
sate for this by applying greater force to the
brake pedal.
For safety reasons, Mercedes-Benz recom-
mends that you only have brake pads/linings
fitted to your vehicle which have been
approved for Mercedes-Benz vehicles or
which correspon dtoanequivalent quality
standard. Brake pads/linings which have not
been approved for Mercedes-Benz vehicles or
which are not of an equivalent quality could
affect your vehicle's operating safety.
AMG high-performance and ceramic
brakes The AMG brake systems are designed for
heavy loads. This may lead to noise when
braking. This is dependent on:

speed
R braking force
R environmental conditions, such as temper-
ature and humidity Driving tips

Important safety notes G
WARNING
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely. G
WARNING
Do not change down for additional engine
braking on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
SPEEDTRONIC is only an aid designed to
assist driving. You are responsible for the
vehicle's speed and for braking in good time.
SPEEDTRONIC brakes automaticallysot hat
you do not exceed the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select shift range
1, 2or 3in good time. 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 overheating and
wearing too quickly. If you need additional
braking, depress the brake pedal repeatedly
rather than continuously.
You can set avariableorp ermanent limit
speed:
R variable for speed limits, e.g. in built-up
areas
R permanent for long-term speed restric-
tions, e.g. when driving with winter tyres
fitted (Y page 170) i
The speed indicated in the speedometer
may differ slightly from the limit speed

WARNING
DISTRONIC PLUS cannot take account of road
and traffic conditions. If DISTRONIC does not
recognise or no longer recognise sthe vehicle
in front, do not activate DISTRONIC or, if it is
already active, deactivate it. This is especially
the case:
R before corners
R on filter lanes
R when changing to alane with faster moving
traffic
R in comple xdriving situations or where lanes
are diverted ,e.g. at roadworks on amotor-
way
DISTRONIC PLUS otherwise maintains the
current spee dset by you or accelerates up to
the set speed.
DISTRONIC PLUS cannot take account of
weather conditions. Deactivate, or do not
activate, DISTRONIC PLUS:
R if the road sare slippery ,snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicl ecould
start to skid.
R if the sensors are dirty or there is poor vis-
ibility ,e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when DISTRONIC PLUS is activated.
Otherwise, you may fail to recognise dangers
in time, caus eanaccident and injure yourself
and others. G
WARNING
DISTRONIC PLUS brakes yourv ehicle up to a
maximum of 4m/s2
depending on its speed.
This corresponds to approximately 40% of
your vehicle's maximum braking power. You
must also apply the brakes yourself if this
braking power is not sufficient.
If DISTRONIC PLUS detect sarisk of collision
with avehicle in front, an intermittent warning
tones ounds. In addition, the ·distance
warning lamp in the instrument cluster lights
up. Brak etoavoidacollision. General notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the dis-
tanc
etot he vehicle detected in front. DIS-
TRONIC PLUS brakes automatically so that
the set speed is not exceeded.
On long and steep downhill gradients, you
must select shift range 1,2or 3in good time.
By doing so, you will make use of the braking
effec tofthe engine. This relieves the load on
the brake system and prevents the brakes
from overheating and wearing too quickly.
If DISTRONIC PLUS detectsas lower-moving
vehicle in front,y our vehicle is braked in order
to maintain the preset distance to the vehicle
in front.
The radar sensor system is switched off auto-
matically in the vicinity of radio telescope
facilities (Y page 368).
If you want DISTRONIC PLUS to assist you,
the radar sensor system must be activated
(Y page 225) and operational.
If there is no vehicle in front,D ISTRONIC
PLUS operates in the same way as cruise
control in the speed range between
30 km/h and 200 km/h. If avehicle is driving
in fron tofyou, DISTRONIC operates in the
speed range between 0km/h and
200 km/h.
Do not use DISTRONIC PLUS on road swith
steep gradients. Driving systems

Obstructions and stationary vehicles
DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example, the
detected vehicle turn sacorner and reveals
an obstacle or stationary vehicle, DISTRONIC
PLUS will not brake for these.
Crossing vehicles DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane. Activat-
ing DISTRONIC PLUS at traffic lights with
crossing traffic, for example, could cause
your vehicle to pull away unintentionally. HOLD function
General notes The HOLD function can assist the driver in the
following situations:
R when pulling away ,especially on steep
slopes
R when manoeuvrin gonsteep slopes
R when waiting in traffic The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effec tiscancelled and the HOLD
function is deactivated when you depress the
accelerator pedal to pull away.
