Fuel filler flap
The fuel filler flap is unlocked or locked
automatically when you open or close the
vehicle with the SmartKey or using KEYLESS-
GO.
The position of the fuel filler flap is to the rear
on the right. The position of the fuel filler cap
is displayed in the instrument cluster 8.
The arrow next to the gas pump indicates the
side of the vehicle.
Example: Sedan
:To open the fuel filler flap;To insert the fuel filler cap=Tire pressure table?Fuel type
Opening
XSwitch off the engine.
iWhen the engine is running and the fuel
filler flap is open, the ; engine
diagnostics warning lamp may light up.
For further information on warning and
indicator lamps in the instrument cluster,
see (Y page 268).
XRemove the SmartKey from the ignition
lock.
KEYLESS-GO: the driver's door is open.
This returns the ignition to position 0,
which corresponds to the SmartKey being
removed. The driver's door can be closed
again.
XPress the fuel filler flap in the direction of
arrow :.
The fuel filler flap opens slightly.
XOpen the fuel filler flap.XTurn the fuel filler cap counter-clockwise
and remove it.
XSedan: insert the fuel filler cap into the
bracket on the inside of fuel filler flap ;.
or
XWagon: holding the fuel filler cap
horizontally, insert it into the recesses in
the fuel filler flap hinge arm from above.
XCompletely insert the filler neck of the fuel
pump nozzle into the tank and refuel.
XOnly fill the tank until the pump nozzle
switches off.
! Overfilling the fuel tank could damage the
fuel system.
Closing
XReplace the fuel filler cap and turn it
clockwise. The fuel filler cap audibly
engages.
iClose the fuel filler flap before locking the
vehicle. A locking pin otherwise prevents
the fuel filler flap from closing after the
vehicle has been locked.
XPress the fuel filler flap closed until it
engages audibly.

Use the special AdBlue ®
refill bottle when
adding between maintenance intervals. For
more information, please contact an
authorized Mercedes-Benz Center or
Roadside Assistance if applicable
( Y page 21).
Further information about BlueTEC exhaust
gas aftertreatment and AdBlue ®
is available
at any authorized Mercedes-Benz Center.
Adding AdBlue ®GWarning!
Make sure
R AdBlue ®
does not come into contact with
skin, eyes, or clothing
R to keep AdBlue ®
out of the reach of children
If you and/or others have come into contact
with AdBlue ®
:
R If AdBlue ®
has gotten into contact with
eyes, flush with plenty of water immediately
and seek medical help.
R Clean affected skin immediately with plenty
of water.
R If AdBlue ®
was swallowed, rinse mouth
immediately with plenty of water and drink
plenty of water. Consult a physician.
GWarning!
When opening the filler cap of the AdBlue ®
tank ammonia gas vapors may escape. Refill
AdBlue ®
in a well ventilated area only.
Ammonia gas vapors have a pungent odor and
are particularly irritating for your skin,
mucous membranes, and eyes. Inhaling
ammonia gas vapors will cause burning eyes,
nose, and throat, as well as coughing and
watering eyes.
! Only use AdBlue ®
that complies with
ISO 22241. Do not add any special
additives to AdBlue ®
and do not thin
AdBlue ®
with water. This could destroy the
BlueTEC exhaust gas aftertreatment.
! Rinse surfaces that have come into
contact with AdBlue ®
immediately with
water or remove AdBlue ®
using a damp
cloth and cold water. If the AdBlue ®
has
already crystallized, use a sponge and cold
water to clean it. AdBlue ®
residues
crystallize after time and contaminate the
affected surfaces.
! AdBlue ®
is not a additive and must not be
added to the diesel tank. If AdBlue ®
is
added to the diesel tank this could damage
the engine.
i If you are adding between maintenance
intervals, add approximately 1 gallon (3.8 l)
of AdBlue ®
to the AdBlue ®
tank. 1 gallon
(3.8 l) of AdBlue ®
is approximately
2 AdBlue ®
refill bottles.

R make sure that only a valve cap approved

Tire pressures that are too low have a
negative effect on vehicle safety, which could
lead you to cause an accident.
Only correct tire pressures when the tires are
cold. The tires are cold when the vehicle has
been parked for at least three hours or driven
for less than 1 mile (1.6 km). The tire
temperature changes depending on the
outside temperature, the vehicle speed and
the tire load. If the tire temperature changes
by 18 ‡ (10 †), the tire pressure changes by
approximately 10 kPa (0.1 bar/1.5 psi). Take
this into account when checking the pressure
of warm tires and only correct the tire
pressure if it is too low for the current
operating conditions. If you check the tire
pressure when the tires are warm, the reading
will be higher than if the tires were cold. This
is normal. Do not reduce the tire pressure to
the value specified for cold tires. The tire
pressure would otherwise be too low.
Observe the recommended tire pressure
specifications for cold tires on the Tire and
Loading Information placard on the B-pillar on
the driver's side.
i The specifications given on the following
Tire and Loading Information placard are
examples. Tire pressure specifications are
vehicle-specific and may deviate from the
data shown here. The tire pressure
specifications for your vehicle can be found
on the Tire and Loading Information placard
of your vehicle.
You will find recommended tire pressure
specifications : for cold tires and for a fully
loaded vehicle on the Tire and Loading
Information placard. The tire pressure
specifications apply to tires which are
installed at the factory.
Important notes on tire pressures
GWarning
If the tire 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.
The temperature and pressure of the tires
increase when the vehicle is in motion. This
is dependent on the driving speed and the
load.
If you wish to drive at high speeds of
100 mph (160 km/h) or higher when this is
allowed, use the tire pressure table on the
inside of the fuel filler flap to set the correct
tire pressures when the wheels are cold. If the
tire pressure is not set correctly, this can lead
to an excessive build up of heat and a sudden
loss of pressure.
For more information, contact a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
i Ride comfort may be affected if the tire
pressure is adjusted to the recommended
value for speeds of over
100 mph(160 km/h).

Important safety notes
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.
Check the tire pressure at least once a month.
Only check and correct tire pressures when
the tires are cold ( Y page 352).
Checking the tire pressures manually
In order to determine and adjust the tire
pressures, proceed as follows:
XRemove the valve cap of the tire you wish
to check.XPress the tire pressure gauge securely onto
the valve.XRead the tire pressure and compare it with
the recommended value on the Tire and
Loading Information placard on the
B-pillar on the driver's side of your vehicle.XIf necessary, increase the tire pressure to
the recommended value ( Y page 352).XIf the tire pressure is too high, release air
by pressing down the metal pin in the valve
using the tip of a pen, for example. Then,
check the tire pressure again using the tire
pressure gauge.XScrew the valve cap onto the valve.XRepeat the steps for the other tires.
Tire pressure loss warning system
(Canada only)
Important safety notes
While the vehicle is in motion, the tire
pressure loss warning system monitors the
set tire pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in a tire. If the speed
of rotation of a wheel changes as a result of
a loss of pressure, a corresponding warning
message will appear in the multifunction
display.
