is not permitted if the vehicle is not parked
on a level surface. There is a danger of
overfilling, which could result in damage to
components of the BlueTE
Cexhaus tgas
aftertreatment.
! Rinse surfaces that have come into
contact with DE Fimmediately with water or
remove DEF using a damp cloth and cold
water. If the DEF has already crystallized,
use a sponge and cold water to clea nit. DEF
residues crystallize after time and
contaminate the affected surfaces.
! DEF is not a fuel additive and must not be
added to the fuel tank. If DEF is added to
the fuel tank, this can lead to engine
damage.
For further information on DEF, see
(Y page 442).
Opening the DEF filler cap The fuel filler flap is unlocked or locked
automatically when you open or close the
vehicle with the SmartKey or with KEYLESS-
GO.
X
Switch the ignition off.
X Press the fuel filler flap in the directio nof
arrow 0002.
The fuel fille rflap swings up.
X Turn blue DE Ffiller cap 0003counter-
clockwise and remove it.
DEF filler cap 0003is secured with a plastic
strip. DEF refill bottle !
Only screw on the DE Frefill bottle hand-
tight .Itcould otherwise be damaged. X
Unscrew the protective cap from DEF refill
bottle 0002.
X Place DEFr efill bottle0002on the filler neck
as shown and screw it on clockwise until
hand-tight.
X Press DEFr efill bottle0002towards the filler
neck.
The DEFt ank is filled. This may take up to
one minute.
i When DE Frefill bottle 0002is no longer
pressed, filling stops and the bottle may be
taken off again after being only partially
emptied.
X Release DEFr efill bottle0002.
X Turn DEFr efill bottle 0002counter-clockwise
and remove it.
X Screw the protective cap onto DEF refill
bottle 0002again.
DEFr efill bottles can be obtained at many gas
stations or at an authorized Mercedes-Benz
Center .Refill bottles without a threaded cap
do not provide overfill protection. DEF may
leak if overfilled. Mercedes Benzo ffers
special refill bottles with a threaded seal.
These are available at any authorized
Mercedes-Benz Center. 182
RefuelingDriving and parking

Never exceed the maximum permissible tire
inflation pressure. Always observe the
recommended tire pressure for yourv
ehicle
when adjusting the tire pressure
(Y page 404).
i The actual values for tires are vehicle-
specific and may deviate from the values in
the illustration. Checking the tire pressures
Important safety notes Observe the notes on tire pressure
(Y
page 404).
Information on air pressure for the tires on
your vehicle can be found:
R on the vehicle's Tire and Loading
Information placard loading information
table on the B-pillar (Y page 412)
R on the tire pressure label on the fuel filler
flap
R in the "Tire pressure" section
R under "Tire pressure" (Y page 404)
Checking tire pressures manually To determine and set the correct tire
pressure, proceed as follows:
X Remove the valve cap of the tire that is to
be checked.
X Press the tire pressure gauge securely onto
the valve.
X Read the tire pressure and compare it with
the recommended value on the Tire and
Loading Information placard (Y page 404).
X If the tire pressure is too low, increase it to
the recommended value.
X If the tire pressure is too high, release air
by pressing down the metal pin in the valve.
Use the tip of a pen, for example. Then,
chec kthe tire pressure again using the tire
pressure gauge.
X Screw the valve cap onto the valve.
X Repeatt hese steps for the other tires. Tire pressure loss warning system
(Canada only)
General 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 appearint
he multifunction
display.
You can recognize the tire pressure loss
warning by the Run Flat Indicator Active Press 'OK' to Restart message
which appears in the Serv. menu of the
multifunction display. Information on the
message display can be found under
"Restarting the tire pressure loss warning
system" (Y page 408).
Important safety notes The tire pressure warning system does not
warn you of an incorrectly set tire pressure.
Observe the notes on the recommended tire
pressure (Y
page 404).
The tire pressure loss warning does not
replace the need to regularly check the tire
pressure. An even loss of pressure on several
tires at the same time cannot be detected by
the tire pressure loss warning system.
The tire pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tire is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Avoid
abrupt steering maneuvers.
The function of the tire pressure loss warning
system is limited or delayed if:
R snow chains are mounted on your vehicle's
tires.
R road conditions are wintry.
R you are driving on sand or gravel. Check
407Wheels and tires Z

components could overhea
twithout being
noticed. There is a risk of fire.
Never refuel with gasoline. Never mix gasoline
with diesel fuel.
! Only use commercially available vehicular
ULTRA-LOW SULFUR DIESEL FUEL (ULSD,
15 ppm maximum sulfur content) that
meets the ASTM D975 standard. If you do
not refuel with ULSD, you may damage the
BlueTEC exhaust gas aftertreatment
system of the vehicle.
! Do not use gasoline to refuel vehicles with
a diesel engine. Do not mix diesel fuel with
gasoline, kerosene or paraffin. This may
otherwise result in damage to the fuel
system and engine.
You will usually find information about the fuel
grade on the pump. If you cannot find the
label on the pump, ask the staf ffor
assistance.
i For further information, consult a
qualified specialist workshop or on the
Internet at http://www.mbusa.com (USA
only).
Information on refueling (Y page 178).
Bio-diesel -FAME (fatt yacid methyl ester)
Mercedes-Ben zUSA approves the use of bio-
diesel B5 for all BlueTEC diesel engines. The
concentration of bio-diesel in the ULSD may
not exceed 5% by volume.
Pure bio-diesel and diesel fuel with a higher
percentage of bio-diesel, such as B20, can
damage the engine and the fuel system. For
this reason, they are not approved.
For more information, consult the gas station
staff. The bio-diesel B5 label on the gasoline
pump mus tclearly state that the standard for
ULS Dhas been fulfilled. If the label is not
clear, do no trefuel the vehicle.
Do not refuel your vehicle with fuels unless
they have been approved by Mercedes-Benz.
Information on refueling (Y page 178).Low outside temperatures
i
Diesel fuel with improved cold flow
properties is available during the winter
months. Further information about fuel
properties can be obtained from oil
companies, e.g. at gas stations.
Flow improver
To improve the low-temperature resistance of
diesel fuel, a flow improver can be attached.
The effectiveness of a flow improver is not
guaranteed for every fuel.
Only use flow improvers tested and approved
by Mercedes-Benz. Durin guse, please
observe the information on operation.
Correct dosage and sufficient mixing are
decisive in improving low-temperature
resistance with the flow improver.
Overdosage can potentially even decrease
low-temperature resistance and must
therefore be avoided.F ollow the
manufacturer's guidelines on dosage.
Mix the additive into the diesel in good time,
before the flow characteristics of the diesel
become insufficient. Otherwise, malfunctions
can arise through heating the fuel system,
e.g. through parking in a heated garage.
More information about recommended flow
improvers can be obtained from any qualified
specialist workshop. DEF
