Index

Never allow sparks, flames or smoking
materials near gasoline.
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and any skin or clothing
contact.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging to your
health.
! Do not use diesel to refuel vehicles with a
gasoline engine. Even small amounts of the
wrong fuel result in damage to the fuel
system and engine.
! Do not switch on the ignition if you
accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel lines.
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 refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
If you overfill the fuel tank, pressure may build
up in the fuel tank. This could cause fuel to
spray out when the fuel pump nozzle is
removed. There is a risk of injury. The fuel
tank is full when the fuel pump nozzle first
switches off. End the refueling process.

RefuelingDriving and parking

The multifunction display shows a service
message for several seconds, e.g.:
Service A in 99999 Miles
Service A in 99999 Miles
Service A Due Now Service A Due Now
Service A Exceeded By 99999 Miles Service A Exceeded By 99999 Miles
Maintaining the time-dependent service
schedule:
X Before disconnecting the battery, note
down the service due date displayed.
or:
X After reconnecting the battery, subtract
the battery disconnection periods from the
service date shown on the display.
i The service interval display should not be
confused with the 4engine oil level
display.
The symbol and the letter indicate which type
of service is due:
¯ Minor service A
A
± Major service B B
The ASSYST service interval display does not
take into account any periods of time during
which the battery is disconnected.
Hiding a service message X
To hide the service message, press the
% back button on the multifunction
steering wheel (Y page 33).
Displaying service messages Use the buttons on the multifunction steering
wheel.
X Switch on the ignition.
X Press VorU to select the standard
display menu on the steering wheel
(Y page 144).
X Select &or* to select the service
interval display.
The ¯ or± service symbol and the
service due date are displayed. Points to remember The specified maintenance interval takes only
the normal operation of the vehicle into
account. Under arduous operating conditions
or increased load on the vehicle,
maintenance work must be carried out more
frequently, for example:
R
regular city driving with frequent
intermediate stops
R if the vehicle is primarily used to travel
short distances
R use in mountainous terrain or on poor road
surfaces
R if the engine is often left idling for long
periods
Under these or similar conditions, have, for
example, the air filter, engine oil and oil filter
replaced or changed more frequently. Under
arduous operating conditions, the tires must
be checked more often. Further information
can be obtained at a qualified specialist
workshop, e.g. an authorized Mercedes-Benz
Center. Fuel/water separator
H
Environmental note
Dispose of service products in an
environmentally responsible manner.
! If you continue driving without having the
fuel/water separator serviced, this could
cause damage to the engine. Any resulting
damage is not covered by the warranty.
If the fuel/water separator needs servicing,
the following message appears in the
multifunction display: You will also hear a brief warning tone. Maintenance

Fuel
Important safety notes G
WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and
explosion.
You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before
refueling. G
WARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come
into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following:
R Wash away fuel from skin immediately
using soap and water.
R If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance
without delay.
R If fuel is swallowed, seek medical
assistance without delay. Do not induce
vomiting.
R Immediately change out of clothing which
has come into contact with fuel.

!
Do not use diesel to refuel vehicles with a
gasoline engine. Even small amounts of the
wrong fuel result in damage to the fuel
system and engine.
! You should only refuel with unleaded
premium-grade gasoline as this avoids
damaging the catalytic converter.
If engine running problems are apparent,
have the cause checked immediately and
repaired. Excess unburned fuel can
otherwise enter the catalytic converter,
leading to overheating and possibly
causing a fire.
! To ensure the longevity and full
performance of the engine, only premium-
grade unleaded gasoline may be used.
If there is no premium-grade unleaded
gasoline available and regular unleaded
gasoline must be used, please observe the
following precautions:
R only fill the fuel tank to half full with
regular unleaded gasoline and fill the rest
with premium-grade unleaded gasoline
as soon as possible.
R do not drive at the maximum speed.
R avoid sudden acceleration.
R if the vehicle is carrying a light load, e.g.
two passengers without luggage, do not
allow the engine to rev above 3000 rpm.
R if the vehicle is fully loaded or is being
operated in mountainous terrain, do not
depress the accelerator pedal further
than Ôof the pedal travel.
! Use a filter when refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
Only refuel using premium-grade unleaded
gasoline with a minimum octane rating of 91. Service products and filling capacities

For a list of approved products, consult an
authorized Mercedes-Benz Center. Comply
with the instructions for use on the product
label.
Do not mix other fuel additives with fuel. This
causes unnecessary costs and could damage
the engine.
Notes on fuel consumption H
Environmental note
CO 2(carbon dioxide) is the gas which
scientists believe to be principally responsible
for global warming (the greenhouse effect).
Your vehicle's CO 2emissions are directly
related to fuel consumption and therefore
depend on:
R efficient use of the fuel by the engine
R driving style
R other non-technical factors, such as
environmental influences, road conditions
or traffic flow
You can minimize your vehicle's CO 2
emissions by driving carefully and having it
serviced regularly.
The vehicle will use more fuel than usual in
the following situations:
R at very low outside temperatures
R in city traffic
R on short journeys
R in mountainous terrain
R when towing a trailer Engine oil

Notes on engine oil
R Additives
R Viscosity Refrigerant of the air-conditioning
system
! Never use refrigerant R 12 (CFC) or
mineral lubricants. Otherwise, you could
damage the air-conditioning system.
The air-conditioning system is filled with
R134a (HFC) refrigerant and a special PAG
lubricant. Brake fluid
G
WARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluid is too low, vapor pockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
Observe the important safety notes for
service products (Y page 258).
Only use brake fluid approved by Mercedes-
Benz according to MB Approval 331.0.
Information about approved brake fluid can
be obtained at any qualified specialist Service products and filling capacities
