R Service

facilities or replacement parts may
not be readily available.
R Unleaded gasoline for vehicles with
catalytic converters may not be available;
the use of leaded fuels will damage the
catalysts.
R Gasoline may have a considerably lower

G
Warning!
Work improperly carried out on electronic
components and associated software could
cause

them to cease functioning. Because the
vehicle’s electronic components are
interconnected, any modifications made may
produce an undesired effect on other
systems. Electronic malfunctions could
seriously impair the operating safety of your
vehicle.
Contact an authorized Mercedes-Benz Center
for repairs or modifications to electronic
components.
Other improper work or modifications on the
vehicle could also have a negative impact on
the operating safety of the vehicle.
Some safety systems only function while the
engine is running. You should therefore never
turn off the engine while driving. G
Warning!
Heavy blows against the vehicle underbody or
tires/wheels may cause serious damage and
impair the operating safety of your vehicle.
Such blows can be caused, for example, by
running over an obstacle, road debris or a
pothole. If you feel a sudden significant
vibration or ride disturbance, or you suspect
that damage to your vehicle as occurred:
R turn on your hazard warning flashers
R slow down carefully
R drive

with caution to an area which is a safe
distance from the road
Inspect the vehicle underbody and tires/
wheels for possible damage. If the vehicle
appears unsafe, have it towed to the nearest
authorized Mercedes-Benz Center or other
qualified maintenance or repair facility for
further inspection or repairs. 22

drained completely. Contact an authorized
Mercedes-Benz Center to have the fuel
system drained completely.
! Gasoline engine:
To prevent damage to the catalytic
converters, only use premium unleaded
gasoline in this vehicle.
Any noticeable irregularities in engine
operation should be repaired promptly.
Otherwise, excessive unburned fuel may
reach the catalytic converter, causing it to
overheat and potentially start a fire.
! Diesel engine:
When filling the diesel fuel tank using fuel
containers, place a filling filter, a suede
cloth or a clean flannel cloth as a filter.
Otherwise, particles from the fuel container
could clog the fuel lines and/or the diesel
injection system.
! Diesel engine:
The engine is more susceptible to wear and
damage if you use
R marine diesel fuel
R heating oil
R additives
The exhaust aftertreatment device will be
seriously damaged if you use any other
diesel fuel than ULTRA-LOW SULFUR
HIGHWAY DIESEL FUEL (15 ppm SULFUR
MAXIMUM).
The use of such non-approved fuels and/or
special additives is not covered by the
Mercedes-Benz Limited Warranty.
i Gasoline engine:
Only use premium unleaded gasoline with
a minimum Posted Octane Rating of 91
(average of 96 RON/86 MON).
Information on gasoline quality can
normally be found on the fuel pump. Please
contact gas station personnel in case
labels on the pump cannot be found. For more information on gasoline, see
“Premium unleaded gasoline (gasoline
engine)” (
Y page 353), see “Fuel
requirements” ( Y page 353), or contact an
authorized Mercedes-Benz Center, or visit
www.mbusa.com (USA only).
i Diesel engine:
Only use commercially available vehicular
ULTRA-LOW SULFUR DIESEL FUEL
(15 ppm SULFUR MAXIMUM). Information
on diesel quality can normally be found on
the fuel pump. Please contact gas station
personnel in case labels on the pump
cannot be found.
For more information on diesel fuels, see
“Fuel requirements” (Y page 353), or
contact an authorized Mercedes-Benz
Center, or visit www.mbusa.com (USA
only).
i Diesel engine:
If you have driven the vehicle until the tank
is empty, the fuel system needs to be bled
(Y page 331).
The fuel filler flap is located on the right-hand
side of the vehicle towards the rear.
Locking/unlocking the vehicle with the
SmartKey or KEYLESS-GO automatically
locks/unlocks the fuel filler flap.
i In case the central locking system does
not release the fuel filler flap, see “Fuel filler
flap” (Y page 309). X

Notes
! Only

use tires which have been tested and
approved by Mercedes-Benz. Tires
approved by Mercedes-Benz are developed
to provide best possible performance in
conjunction with the driving safety systems
on your vehicle such as the ABS or the
ESP ®
. Tires specially developed for your
vehicle and tested and approved by
Mercedes-Benz can be identified by finding
the following on the tire’s sidewall:
R MO = Mercedes-Benz Original
equipment tires
R MOE

= Mercedes-Benz Original Extended
(tires with limited run-flat
characteristics) original equipment tires
Using tires other than those approved by
Mercedes-Benz may result in damage that
is not covered by the Mercedes-Benz
Limited Warranty.
For information on driving with MOExtended
tires, see the “Practical hints” section
(Y page 330).

the formation of bubbles in the system, thus
reducing the system’s efficiency.
Therefore, the brake fluid must be replaced
regularly.
Refer to your vehicle’s Maintenance
Booklet for replacement interval.
Only brake fluid approved by Mercedes-Benz
is recommended. Any authorized Mercedes-
Benz Center will provide you with additional
information. Premium unleaded gasoline (gasoline
engine)
G
Warning!
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
personal injury.
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. Extinguish all smoking materials.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging your
health.
! To maintain the engine’s durability and
performance, premium unleaded gasoline
must be used.
If premium unleaded gasoline is not
available and low octane gasoline is used,
follow these precautions:
R Have the fuel tank only partially filled
with

unleaded regular gasoline and fill up
with premium unleaded gasoline as soon
as possible.
R Avoid full throttle driving and abrupt
acceleration.
R Do not exceed an engine speed of
3 000 rpm if the vehicle is loaded with a light load such as two persons and no
luggage.
R Do not exceed 2
/ 3 of maximum
accelerator pedal position if the vehicle
is fully loaded or operating in
mountainous terrain. Fuel requirements
Gasoline engine Only use premium unleaded gasoline. The
octane

number (posted at the pump) must be
91 min. It is an average of both the Research
Octane Number (RON) and the Motor Octane
Number (MON): (RON+MON)/2. This is also
known as the ANTI-KNOCK INDEX.
Reformulated gasolines (RFG) and/or
unleaded gasoline containing oxygenates
such as ethanol, TAME, ETBE, IPA, IBA, and
TBA can be used provided the ratio of any one
of these oxygenates to gasoline does not
exceed 10%; MTBE must not exceed 15%.
The ratio of methanol to gasoline must not
exceed 3% plus additional cosolvents.
Using mixtures of ethanol and methanol is not
allowed. Gasohol, which contains 10%
ethanol and 90% unleaded gasoline, can be
used.
These blends must also meet all other fuel
requirements, such as resistance to spark
knock, boiling range, vapor pressure, etc.
Diesel engine Only use commercially available vehicular
ULTRA-LOW

SULFUR HIGHWAY DIESEL FUEL
(15 ppm SULFUR MAXIMUM) that meets the
ASTM D975 standard. Failure to use
ULTRA-LOW SULFUR HIGHWAY DIESEL FUEL
can severely damage the vehicle’s exhaust
after-treatment device.
To prevent malfunctions, diesel fuel with
improved cold flow characteristics is offered
in the winter months. Check with your fuel
retailer. Fuels, coolants, lubricants, etc.
