Important safety notes G
WARNING
If you switch off th eignitio nwhile 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. G
WARNING
If you operate mobile communication
equipment while driving, you will be
distracted from traffic conditions. You could
also lose control of the vehicle. There is arisk
of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements for the
country in which you are driving. Some
jurisdiction sprohibit the driver from using a
mobile phone while driving avehicle.
If you make acall while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are unsure, pull over to
asafe location and stop
before operating the telephone.
Bear in mind that at aspeed of only 30 mph
(approximately 50 km/h) ,the vehicle covers
ad istance of 44 ft (approximately 14 m) per
second.
Drive sensibly –save fuel Observe the following tips to save fuel:
R The tires should always be inflated to the
recommended tire pressure.
R Remove unnecessary loads.
R Remove roof racks whe nthey are not
needed.
R Warm up the engine at low engine speeds.
R Avoid frequent acceleration or braking.
R Have all maintenancew ork carried out as
indicated by the service intervals in the
MaintenanceB ooklet or by the service
interval display.
Fuel consumption also increases when
driving in cold weather, in stop-start traffic
and in hilly terrain.
Drinking and driving G
WARNING
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even asmall amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment.
The possibility of aserious or even fatal
accident is greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Emission control G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There Driving tips

i
On long journeys at aconstant speed, e.g.
on the highway, only the bar for Constantwill change.
i The ECO displays ummaries the driving
characteristics from the start of the journey
to its completion. For this reason, the bars
change dynamically at the beginning of the
journey. On longer journeys, there are
fewer changes. For more dynamic changes,
carry out amanual reset.

Important safety notes G
WARNING
If you shift down on aslippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine
braking on aslippery road surface.
Downhill gradients !
On long and steep gradients, you must
reduce the load on the brakes by shifting to
al ower gear in good time. This allows you
to take advantage of the engine's braking
effect. For this, you need to have selected
manual drive program M.This helps you to
avoid overheating the brakes and wearing
them out excessively.
When you take advantage of the engine's
braking effect,ad rive wheel may not turn
for some time, e.g. on aslippery road
surface. This could cause damage to the
drive train. This type of damage is not
covered by the Mercedes-Ben zwarranty.
i Briefl ydepressing th eaccelerato rpedal
on downhill gradient swhile the manual
drive program Mis temporarily activated:
the automatic transmission may switch to the last activ
eautomatic drive program E
or S.T he automatic transmission may shift
to ah igher gear. This can reduce the
engine's braking effect.
Heavy and light loads G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as afootrest .Never
depress the brake pedal and the accelerator
pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to aheavy
load, do not stop the vehicle immediately.
Driv eonf oras hort while. This allows the
airflow to cool the brakes more quickly.
Wet roads If you have driven for
along time in heavy rain
without braking ,there may be adelayed
reaction 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
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.
Limited braking performance on salt-
treated roads If you drive on salted roads,
alayer of salt
residue may form on the brake discs and Driving tips

If DISTRONIC PLUS detects
afaster-moving
vehicle in front, it increases the driving speed.
The vehicle is only accelerated up to the
speed you have stored.
Changing lanes
If you change to the passing lane, DISTRONIC
PLUS supports you when:
R you are driving faster than 40 mph
(60 km/h)
R DISTRONIC PLUS is maintaining the
distance to avehicle in front
R you switch on the appropriate turn signal
R DISTRONIC PLUS does not detect adanger
of collision
If these conditions are fulfilled,y ourv ehicle
is accelerated. Acceleration will be
interrupted if changin glanes takes too long
or if the distanc ebetween your vehicle and
the vehicle in fron tbecomes too small.
i When changin glanes, DISTRONIC PLUS
monitors the left lane on left-hand drive
vehicles and the right lane on right-hand
drive vehicles.
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 a
vehicle occupan torfrom outsid ethe
vehicle.
R the electrica lsystem in the engine
compartment, the battery or the fuses have
