Refueling
GWarning!
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.
GWarning!
Overfilling of the fuel tank may create
pressure in the system which could cause a
gas discharge. This could cause the gas to
spray back out when removing the fuel pump
nozzle, which could cause personal injury.
!  Never refuel vehicles with gasoline engine
with diesel fuel. Even small amounts of
diesel fuel will damage the fuel system and
engine. Damage resulting from the use of
non-approved fuels or fuel additives or
resulting from mixing gasoline with diesel
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 425), see “Fuel requirements”
( Y  page 427), or contact an authorized
Mercedes-Benz Center, or visit
http://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

For information on quantities and
requirements of operating agents, see “Fuels,
coolants, lubricants, etc.” ( Y page 425).
Check the following:
R Engine oil level ( Y page 323)
R Tire inflation pressure ( Y page 329)
R Coolant level ( Y page 324)
At the gas station321OperationBA 197 USA, CA Edition A 2011; 1; 27, en-UShereepeVersion: 3.0.3.52010-03-24T15:31:10+01:00 - Seite 321Z  

sharply reduced at tread depths of less
than   1
/ 8  in (3 mm).
R When replacing individual tires, you should
mount new tires on the front wheels first
(on vehicles with same-sized wheels all
around).
Recommended tire inflation pressure
GWarning!
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.
Your vehicle is equipped with the Tire and
Loading Information placard located on the
driver’s door B-pillar ( Y page 334).
The tire inflation pressure should be checked
regularly. Only adjust the tire inflation
pressure on cold tires. The tires can be
considered cold if the vehicle has been
parked for at least 3 hours or driven less than
1 mile (1.6 km). Depending on the ambient
temperature, the driving speed and the tire
load, the tire temperature changes. When the
tire temperature changes by 18 ‡ (10†), the
tire inflation pressure will change by
approximately 10 kPa (0.1 bar, 1.5 psi). Keep
this in mind when checking tire inflation
pressure on warm tires and adjust the tire
pressure only if the tire inflation pressure is
too low for the current operating conditions.
If you check the tire inflation pressure when
the tires are warm, the reading will be higher
than the cold reading. This is normal. Do not
let air out to match the specified cold tire
inflation pressure. Otherwise, the tire will be
underinflated.
Follow recommended cold tire inflation
pressures listed on Tire and Loading
Information placard on the driver’s door
B-pillar.
Keeping the tires properly inflated provides
the best handling, tread life and riding
comfort.
In addition to the Tire and Loading
Information placard on the driver’s door
B-pillar, also consult the tire inflation
pressure label on the inside of the filler flap
for any additional information pertaining to
special driving situations. For more
information, see “Important notes on tire
inflation pressure” ( Y page 328).
i Data shown on Tire and Loading
Information placard example are for
illustration purposes only. Tire data are
specific to each vehicle and may vary from
data shown in the following illustration.
Refer to Tire and Loading Information
placard on vehicle for actual data specific
to your vehicle.
The Tire and Loading Information placard lists
the recommended cold tire inflation
pressures  0046 for maximum loaded vehicle
Tires and wheels327OperationBA 197 USA, CA Edition A 2011; 1; 27, en-UShereepeVersion: 3.0.3.52010-03-24T15:31:10+01:00 - Seite 327Z  

weight. The tire inflation pressures listed
apply to the tires installed as original
equipment.
Important notes on tire inflation
pressure  GWarning!
If the tire inflation pressure drops repeatedly,
check the tires for punctures from foreign
objects and/or whether air is leaking from the
valves or from around the rim.
Tire temperature and tire inflation pressure
are also increased while driving, depending
on the driving speed and the tire load.
If you will be driving your vehicle at high
speeds of 100 mph (160 km/h) or higher,
where it is legal and conditions allow, consult
the tire inflation pressure label on the inside
of the fuel filler flap on how to adjust the cold
tire inflation pressure. If you do not adjust the
tire inflation pressure, excessive heat can
build up and result in sudden tire failure.
If you are not sure about the proper tire
inflation pressure, contact an authorized
Mercedes-Benz Center.
i Driving comfort may be reduced when the
tire inflation pressure is adjusted to the
value for speeds above 100 mph
( 160 km/h) as specified on the tire inflation
pressure label located on the inside of the
fuel filler flap.
Make sure to readjust the tire inflation
pressure for normal driving speeds.
Supplemental tire inflation pressure
information for different loading conditions of
the vehicle can be found on the tire inflation
pressure label. The tire inflation pressure
label is located on the inside of the fuel filler
flap.
Unless specified otherwise, the tire inflation
pressures on the tire inflation pressure label
are valid for all approved, factory-equipped
tires.
i Data shown on tire inflation pressure
label examples are for illustration purposes
only. Tire inflation pressure data are
specific to each vehicle and may vary from
data shown in the following illustrations.
Refer to the tire inflation pressure label on
vehicle for actual data specific to your
vehicle.
Potential problems associated with
underinflated and overinflated tires  
Underinflated tires
GWarning!
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires
