fuel is not covered by the Mercedes-Benz
Limited Warranty.
! If you have accidentally filled the tank
with incorrect or non-approved fuel, do not
switch on the ignition. Otherwise the
incorrect or non-approved fuel will get into
the fuel lines. The fuel system must be
drained completely. Contact an authorized
Mercedes-Benz Center to have the fuel
system drained completely.
! 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.
i 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”
(Y page 303), see “Fuel requirements”
(Y page 303), or contact an authorized
Mercedes-Benz Center, or visit
www.mbusa.com (USA only).
Locking/unlocking the vehicle with the
SmartKey automatically locks/unlocks the
fuel filler flap.
i In case the central locking system does
not release the fuel filler flap, or the
opening mechanism is clamping, contact
Roadside Assistance or an authorized
Mercedes-Benz Center.
The fuel filler flap is located on the right-hand
side of the vehicle towards the rear. X
Turn off the engine.
i Leaving the engine running and the fuel
filler cap open can cause the yellow fuel
tank reserve warning lamp to flash and the
malfunction indicator lamp ! (USA
only) or ; (Canada only) to illuminate.
For more information, see also “Practical
hints” (Y page 262).
X Remove the SmartKey from the starter
switch.
X Opening: Press fuel filler flap : at the
point indicated by the arrow.
X Turn fuel filler cap ; counterclockwise.
X Take off fuel filler cap ;.
X Place fuel filler cap ; in direction of arrow
into holder =.
X Fully insert filler nozzle unit and refuel.
X Only fill your tank until the filler nozzle unit
cuts out – do not top off or overfill .
X Closing: Turn fuel filler cap ; clockwise
until it audibly engages.
i Close the fuel filler flap before locking the
vehicle. Otherwise the flap locking pin will
prevent closing the fuel filler flap.
X Close fuel filler flap :. Check regularly and before a long trip

R adversely affect handling characteristics
R cause uneven tire wear
R be more prone to damage from road
hazards

R increase stopping distance Checking tire inflation pressure
Safety notes G
Warning!
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are
more likely to fail from being overheated.
Do
not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver’s door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading the tires can also result
in handling or steering problems, or brake
failure.
Check the tire inflation pressure at least once
a month.
Check and adjust the tire inflation pressure
when the tires are cold ( Y page 198).Checking tire inflation pressure
manually Follow the steps below to achieve correct tire
inflation pressure:
X
Remove the cap from the valve on one tire.
X Firmly press a tire gauge onto the valve.
X Read the tire inflation pressure on the tire
gauge and check against the
recommended

tire inflation pressure on the
Tire and Loading Information placard on the
driver’s door B-pillar ( Y page 205). If
necessary, add air to achieve the
recommended tire inflation pressure.
X If you have overfilled the tire, release tire
inflation pressure by pushing the metal
stem of the valve with e.g. a tip of a pen.
Then recheck the tire inflation pressure
with the tire gauge.
X Install the valve cap.
X Repeat this procedure for each tire.
Advanced Tire Pressure Monitoring
System (Advanced TPMS), (USA only) Your vehicle is equipped with the Advanced
Tire Pressure Monitoring System (Advanced
TPMS).

It measures the tire inflation pressure
in the vehicle’s tires and issues warnings in
case of pressure loss in one or more of the
tires.
The TPMS is equipped with a combination low
tire pressure/ TPMS malfunction telltale in
the instrument cluster. Depending on how the
telltale illuminates, it indicates a low tire
pressure condition or a malfunction in the
TPMS system itself:
R If the telltale illuminates continuously, one
or more of your tires is significantly
underinflated. There is no malfunction in
the TPMS.
R If the telltale flashes for 60 seconds and
then stays illuminated, the TPMS system
itself is not operating properly.
The TPMS only functions on wheels that are
equipped with the proper electronic sensors. Tires and wheels

may vary from data shown in above
illustration.
This is the maximum permissible tire inflation
pressure : for the tire.
Always follow the recommended tire inflation
pressure ( Y page 198) for proper tire
inflation. Loading the vehicle
Two labels on your vehicle show how much
weight it may properly carry.
(1) The Tire and Loading Information placard can be found on the driver’s door
B-pillar. This placard tells you important
information about the number of people
that can be in the vehicle and the total
weight that can be carried in the vehicle.
It also contains information on the proper
size and recommended tire inflation
pressures for the original equipment tires
on your vehicle.
(2) The certification label, also found on the driver’s door B-pillar. It tells you about the
gross weight capacity of your vehicle,
called the Gross Vehicle Weight Rating
(GVWR). The GVWR includes the weight
of the vehicle, all occupants, fuel and
cargo. The certification label also tells
you about the front and rear axle weight
capacity, called the Gross Axle Weight
Rating (GAWR).
The GAWR is the total allowable weight
that can be carried by a single axle (front
or rear). Never exceed the GVWR or
GAWR for either the front axle or rear
axle. :

Tire type code
Tire type code
? may, at the option of the
manufacturer, be used as a descriptive code
for identifying significant characteristics of
the tire.
Date of manufacture The date of manufacture
A identifies the
week and year of manufacture.
The first two figures identify the week,
starting with “01” to represent the first full
week of the calendar year. The second two
figures represent the year.
For example, “3208” represents the 32nd
week of 2008. Tire ply material

on tires are specific to each vehicle and
may vary from data shown in above

Accessory weight The combined weight (in excess of those
standard items which may be replaced) of
automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to the extent that these
items are available as factory-installed
equipment (whether installed or not).
Air pressure The amount of air inside the tire pressing
outward on each square inch of the tire. Air
pressure is expressed in pounds per square
inch (psi), kilopascal (kPa), or bar.
Aspect ratio
Dimensional relationship between tire
section height and section width expressed
in percentage.
Bar
Metric unit for air pressure. There are
14.5038 pounds per square inch (psi) to
1 bar; there are 100 kilopascals (kPa) to 1 bar.
Bead
The tire bead contains steel wires wrapped by
steel cords that hold the tire onto the rim.
Cold tire inflation pressure
Tire inflation pressure when your vehicle has
been sitting for at least 3 hours or driven no
more than 1 mile (1.6 km).
Curb weight
The weight of a motor vehicle with standard
equipment including the maximum capacity
of fuel, oil, and coolant, and, if so equipped,
