Problems with the fuel and fuel tank
If your vehicle is losing fuel, the fuel lines or thefuel tank are defective.
XTurn the key immediately to position 0in the
ignition lock and remove it.
XDo not restart the engine under any circum-
stances.
XConsult a qualified specialist workshop.
If the fuel tank has been run dry, after refueling
carry out the following steps:
XBefore starting the engine: switch on the igni-
tion three or four times.
XTurn the key to position 2in the ignition lock
(Ypage 119).
The % preglow indicator lamp in the instru-
ment cluster lights up briefly.
XOnce the %preglow indicator lamp goes
out, turn the key to position 3in the ignition
lock and release it as soon as the engine is
running.
You can start the diesel engine without preglow
when the engine is warm.
Diesel Exhaust Fluid (DEF)
Important safety notes
!Only use DEF in accordance with
ISO 22241. Never mix DEF with additives or
thin it with tap water. The exhaust gas after-
treatment may otherwise be damaged.
Observe the MB Specifications for Service
Products, Sheet 352.0.
Damage that results from the use of additives
or tap water leads to the loss of the New
Vehicle Limited Warranty.
!If DEF comes into contact with a painted or
aluminum surface, wash the surface off
immediately with plenty of water.
!DEF is not a diesel additive and must not be
mixed with fuel in the tank. Even small
amounts of DEF can cause engine damage.
Damage that results from the blending of DEF
will not be covered by the New Vehicle Limi-
ted Warranty.
iIf the outside temperature is below 12 ‡
( Ò 11 †) it may be difficult to top up. If the DEF
is frozen and there is an active warning indi- cator, topping up may not be possible. Park
the vehicle in a warm place, e.g. in a garage,
until the DEF has become liquid again. Top-
ping up is then possible again. Alternatively,
have the DEF tank refilled at a qualified spe-
cialist workshop.
iIf you add DEF at temperatures below 12 ‡
( Ò 11 †) it is possible that the level is not
shown correctly due to the frozen DEF.
Drive for at least 20 minute s(heating phase in
the tank activated) and then st
op the vehicle
for at least 30 seconds. The level is then
shown correctly.
You will find further information on DEF in the
"Service products" section (
Ypage 278).
Refueling procedure
DEF filler neck
Non-lockable DEF filler cap
Example: DEF filler cap in the engine compartment
XTo open: switch off the ignition.
XOpen the hood (Ypage 219).
XTurn filler cap :counter-clockwise and
remove it.
XTo close: replace cap :on the filler neck and
turn it clockwise.
You will hear a click when cap :is fully
closed.
XClose the hood (Ypage 220).

Driving and parking
Radversely affect ride comfort
Rbe more susceptible to damage
Maximum tire pressures
:Maximum permitted tire pressure (example)
Never exceed the maximum permissible tire
inflation pressure. When adjusting the tire pres-
sures always observe the recommended tire
pressure for your vehicle (
Ypage 251).
iThe actual values for tires are specific to
each vehicle and may deviate from the values in the illustration.
Tire valve
GWARNING
Tire valve that are not approved for your vehi-
cle by the distributor named on the inside
cover page may result in a loss of tire pres-
sure. This may affect road safety. There is a
risk of an accident.
Only use tire valve that are approved for your
vehicle by the distributor named on the inside
cover page. Always make sure you have the
correct tire valve type for the tires on your
vehicle.
!Do not screw additional weights (check
valves, etc.) onto the tire valves. The elec-
tronic components could thus be damaged.
Only for vehicles without a tire pressure moni-
tor:
For safety reasons, Mercedes-Benz recom-
mends that you only use tire valves that have
been tested for use on your vehicle.
Checking the tire pressure manually
In order to determine and adjust the tire pres-
sures, 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 loading informa-
tion table or the tire pressure table
(
Ypage 251).
XIf the tire pressure is too low, increase it to the
recommended value.
XIf 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, 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 monitor
Important safety notes
GWARNING
Each tire, including the spare (if provided),
should be checked at least once a month
when cold and inflated to the pressure rec-
ommended by the vehicle manufacturer on
the Tire and Loading Information placard on
the driver's door B-pillar or the tire pressure
label on the inside of the fuel filler flap. If your
vehicle has tires of a different size than the
size indicated on the Tire and Loading Infor-
mation placard or the tire pressure label, you
should determine the proper tire pressure for
those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires
are significantly underinflated. Accordingly,
when the low tire pressure telltale illuminates,
you should stop and check your tires as soon
as possible, and inflate them to the proper
pressure. Driving on a significantly underin-
