!
Do not use diesel to refuel vehicles with a
gasoline 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 could result in damage to the
fuel system and the engine. The repair
costs are high. Notify aqualified specialist
worksho pand have th efuel tan kand fuel
lines draine dcompletely.
! Overfilling the fuel tank could damage the
fuel system.
! Take car enot to spill any fuel on painted
surfaces .You could otherwise damage the
paintwork.
! Use afilter when refueling from afuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
If you overfill the fuel tank,f uel could spray
out when the fuel pump nozzle is removed.

Important safety notes
G
WARNING
If flammable materials such as leaves, grass
or twigs are exposed to prolonged contact to
parts of the exhaust system that heat up, they
could ignite. There is arisk of fire.
Park the vehicle so that no flammable
materials come into contact with parts of the
vehicle which are hot. Take particular care not
to park on dry grassland or harvested grain
fields. G
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. G
WARNING
If you leave children unsupervised in the
vehicle, they could set it in motion by, for
example:

WARNING
If you must brake the vehicle with the parking
brake, the braking distance is considerably
longer and the wheels could lock. There is an
increased danger of skidding and accidents.
Only use the parking brake to brake the
vehicle when the service brake is faulty. Do
not apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turninga gain.G

second.
Drive sensibly –save fuel Observe the following tips to save fuel:
X
The tires should always be inflated to the
recommended tire pressure.
X Remove unnecessary loads.
X Remove roof racks whe nthey are not
needed.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X 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 are 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
is ar isk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with
the manufacturer's specifications. For this
reason, only have work on the engine carried
out by qualified and authorized Mercedes-
Benz technicians.
The engine settings must not be changed
under any circumstances. Furthermore, all
specific service work must be carried out at
regular intervals and in accordance with the
Mercedes-Ben zservice requirements. Details
can be found in the Maintenance Booklet. ECO display

gstyle in term sofconsumption ,taking
the actual and selected condition sinto
consideration .Your driving style can
significantly influence the vehicle's
consumption.
The ECO display consist softhree bars:
R Acceleration R
Constant R
Coasting The percent value is the average value of the
three bars. The three bars and the mean value
begin at the value of 50%. Ahigher
percentage indicates amoree conomical
driving style.
The ECO display doe snot indicate the actual
fue lconsumption and afixe dp ercentage
count in the ECO display doe snot indicate a

Apart from driving style, consumption is
dependent on many factors such as ,e.g.:
R load
R check
R col ds tart
R choice of route
R electrical consumers switched on
These factors are not taken into
consideration by the ECO display.
The evaluation of your driving styl eiscarried
ou tu sing the following three categories: R
Acceleration (evaluation of all
acceleration processes):
- The bar fills up: moderate acceleration,
especially at higher speeds
- The bar empties: sporty acceleration
R Constant (assessment of driving behavior
at all times):
- The bar fills up: constant speed and
avoidance of unnecessary acceleration
and deceleration
- The bar empties: fluctuations in speed
R Coasting (assessment of all deceleration
processes):
- The bar fills up: anticipatory driving,
keeping your distance and early release
of the accelerator. The vehicle can coast
without use of the brakes.
- The bar empties: frequent braking
i An economical driving style specially
requires driving at moderate engine
speeds.
To achieve ahigher value in the categories
Acceleration and
Constant :
R observe the gearshift recommendations.
R drive in drive program E.
i On long journeys at aconstant speed, e.g.
on the highway, only the bar for Constant will 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.

Braking
Important safety notes G
WARNING
If yo ushift down on aslipper yroads urface in
an attempt to increas ethe engine's braking
effect,t he 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
early to alower gear. This allowsy ou to take
advantage of the engine braking effect and
helps avoid overheating and excessive
wear of the brakes.
When you take advantage of the engine
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.
Do no tdepress the brake pedal continuously
while the vehicle is in motion ,e.g. causing the
brakes to rub by constantly applying light
pressure to the pedal. This results in
excessive and premature wear to the brake
pads.
On long and steep downhill gradients, you
must select shift range 1,2or 3in good time.
This is especially important if the vehicle is
laden.
Heavy and light loads G
WARNING
If you rest your foot on the brake pedal while
driving, the brakin gsystem 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, but
drive on for ashort 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
brake pads. This can result in asignificantly
longer braking distance.
R Brak eoccasionally 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 distanc etothe vehicle
ahead. 172
