wheel and remove the adapter.
XTighten the adapter with the six adapter bolts
evenly in a crosswise pattern through the
outer holes on the wheel hub.

XPush the wheel onto the adapter and attach it.
Mounting a new wheel
GWARNING
Oiled or greased wheel bolts or damaged
wheel bolts/hub threads can cause the wheel bolts to come loose. As a result, you could
lose a wheel while driving. There is a risk of
accident.
Never oil or grease wheel bolts. In the event of
damage to the threads, contact a qualified
specialist workshop immediately. Have the
damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving.
GWARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is a risk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
Always observe the instructions and safety
notes on "Changing a wheel" (
Ypage 267).
Only use wheel bolts or wheel nuts that have
been designed for the wheel and the vehicle. For safety reasons, we recommend that you only
use wheel bolts or wheel nuts which have been
approved for Sprinter vehicles and the respec-
tive wheel.
!For a steel wheel, only use the short wheel
bolts to mount the steel spare wheel. Using
other wheel bolts to mount the steel spare
wheel could damage the brake system.
!On vehicles equipped with a tire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed at a qualified spe-
cialist workshop.

XClean the wheel and wheel hub contact sur-
faces.
XVehicles with Super Single tires: first attach
the adapter for the narrow spare wheel to the
wheel hub (
Ypage 270).
Slide the new wheel onto the wheel hub or
onto the adapter for the spare wheel and push
it on.
Slide the new wheel onto the wheel hub and
push it on.
Wheels with centering by wheel bolts:
XVehicles with alloy wheels: take the short
wheel bolts that secure the steel spare wheel
out of the vehicle tool kit.
XScrew in the wheel bolts and tighten them
lightly.
For wheels with wheel nuts:
XFront wheels with wheel nut covers: press the wheel nut covers onto the wheel nuts.
XScrew in three wheel nuts over the fixing discs
of the wheel nut cover.
XTurn the wheel so that the wheel bolts are in
the middle of the holes.
XScrew on the rest of the wheel nuts.
XSlightly tighten all the wheel nuts.

Diesel Exhaust Fluid (DEF)
General notes
When opening the DEF tank filler cap at high
outside temperatures, ammonia vapors may
escape.
Ammonia vapors have a pungent smell and pri-
marily cause irritation of the:
Rskin
Rmucous membranes
Reyes
You may experience a burning sensation in your
eyes, nose and throat, as well as coughing and
watering of the eyes.
Do not inhale ammonia vapors. Avoid contact
with DEF.
Do not allow DEF to come into direct contact
with your skin; it is hazardous to your health.
Rinse any affected areas off with plenty of clean water. Consult a doctor if necessary.
If DEF heats up, e.g. in direct sunlight, in the DEF
supply reservoir for some time to over 122 ‡
(50 †) , ammonia vapor will develop.
To conform to emission regulations, you must
operate the vehicle with DEF and refill the supply
regularly. The engine management recognizes
attempts to operate the vehicle without DEF,
with thinned DEF or with another reducing
agent. After previous warning messages, the
engine management then prevents a further
engine start.
When the number of remaining engine starts is 0
the engine management prevents the vehicle
from being driven at a speed exceeding 5 mph
(8 km/h). The multifunction display shows the
Idle Mode
message.
DEF consumption
DEF consumption depends on operational and
driving conditions and it is not necessary to wait
until the next scheduled service to replenish the
fluid. Therefore, refill the DEF supply tank regu-
larly during vehicle operation or, at the latest,
after receiving the first warning message via the
on-board computer.
Low ambient temperatures
DEF freezes at a temperature of approximately
12‡(Ò11 †). The vehicle is equipped with a DEF
preheating system at the factory. Winter oper-
ation is therefore also guaranteed at tempera-
tures under 12 ‡ (Ò11 †).
iIf you add DEF at temperatures below 12 ‡
(Ò11 †) it is possible that the level is not
shown correctly due to the frozen DEF.
Drive for at least 20 minutes (heating phase in
the fuel tank activated) and then stop the
vehicle for at least 30 seconds. The level is
then shown correctly.
Additives
!Do not mix DEF with any additives and do
not dilute DEF with tap water. Otherwise, the
exhaust gas aftertreatment may be damaged.
Observe the MB Specifications for Service
Products, Sheet No. 352.0.
Damage that arises through the use of addi-
tives or tap water will invalidate the New Vehi-
cle Limited Warranty.
Storage
!Containers made of aluminum, copper, cop-
per alloys as well as unalloyed or galvanized
steel are not suitable for storing DEF. If stored
in these types of containers, DEF could cause
constituents of these metals to dissolve and
cause irreparable damage to the exhaust gas
aftertrea tment.
Da

mage caused by such impurities in the DEF
will invalidate the New Vehicle Limited War-
ranty.
Only store DEF in containers made of high-alloy
Cr‑ Ni steel or Mo ‑Cr‑Ni steel in accordance with
DIN EN 10 088 ‑1/2/3 or plastic containers
made of polypropylene or polyethylene.
Purity
!Impurities in DEF (e.g. caused by other ser-
vice products, cleaning agents, dust, etc.)
result in increased emissions, malfunctions,
catalytic converter damage or engine dam-
age.
The purity of DEF is essential to prevent mal-
functions in the exhaust gas aftertreatment.
If DEF is pumped out of the DEF tank, e.g. during
repair work, the same liquid must not be used to
refill the tank. Its purity is no longer guaranteed.
