Draining the fuel filter
If the 00BA
indicator lamp lights up, you must
drain the fuel filter.
! When the 00BA indicator lamp lights up,
drain the fuel filter with water separator
immediately. Otherwise, the engine may be
damaged.
0040Environmental note
When handling, storing and disposing of
diesel and diesel mixtures, please observe
the relevant regulations.
To this end, have the fuel filter with water
separator drained at a qualified specialist
workshop which
has

the necessary specialist
knowledge and tools to carry out the work
required, e.g. an authorized Sprinter Dealer.
The fuel filter with water separator is in the
engine compartment. X
Apply the parking brake and move the
automatic
transmission selector

lever to P.
X Switch off the diesel engine and open the
hood ( Y page 168).
X Place a suitable receptacle under drain
hose 0046.
X Turn the key to position 2 in the ignition
lock.
X Open drain plug 0047
immediately until
liquid
flows out of drain hose 0046. Make sure that the liquid flows into the receptacle under
drain hose
0046.
X Screw in drain plug 0047 as soon as
approximately 0.2 US qt (0.2 l) of liquid have been collected.
i The electric fuel pump stops the flow of
liquid automatically after 30 seconds.
X After draining, turn the key back to
position

0 in the ignition lock.
X Dispose of the liquid in an environmentally
responsible manner.
0040Environmental note
Have the drained liquid disposed of at a
qualified specialist workshop, e.g. an
authorized Sprinter Dealer.
X Drain the fuel filter again if the 00BA
indicator lamp remains lit.
! If the
00BA

indicator lamp remains lit even
after draining for the second time, have the
cause checked immediately at a qualified
specialist workshop, e.g. at an authorized
Sprinter Dealer. Bleeding the fuel system
Wheels and tires
General notes
The vehicle is equipped either with a spare
wheel or with

Premium tire sealant. The spare
wheel is under the rear of the vehicle
(Y page 185). The Premium tire sealant is
located in the stowage compartment in the
right-hand door sill ( Y page 184). G
Warning
Defective or worn tires, and underinflated or
overinflated tires, can cause significant
changes in the

vehicle's handling and braking
characteristics. There is an increased risk of
an accident. Wheels and tires

When you have mounted M+S tires:
X
Check the tire pressure (Y page 255).
X Restart the tire pressure monitor
(Y page 258). G
Warning
If you use your spare wheel when M+S tires
are fitted on the other wheels, be aware that
the difference in
tire characteristics may very
well impair turning stability and that overall
driving stability may be reduced. Adapt your
driving style accordingly.
Have the spare wheel replaced by a regular
road wheel with an M+S tire at the nearest
authorized Sprinter Dealer. Snow chains
Snow chains increase traction on roads in
wintry conditions.
We recommend, for safety reasons, that you
only use class

U snow chains or traction aids
that conform to the SAE type U specification
and are approved for Sprinters. You can
obtain information about snow chains from
any authorized Sprinter Dealer.
R Only use snow chains when the road is
covered by a layer of snow. Do not exceed
the maximum permissible speed of 30 mph
(50 km/h). Remove the snow chains as
soon as possible once the road is no longer
covered with snow.
R The use of snow chains may be restricted
by local regulations. Observe the relevant
regulations when mounting snow chains.
! Check the snow chains for damage before
mounting them. Damaged or worn snow
chains may break, causing damage to
wheels, wheel arches or wheel suspension.
For this reason, you must use only snow
chains that are free of defects. Observe the
manufacturer's mounting instructions. If you intend to mount snow chains, please
bear the following points in mind:
R
You may not mount snow chains on all
wheel/tire combinations. When mounting
the snow chains, note the permissible tire
and snow chain dimensions.
R Mount snow chains only in pairs and only
to the rear wheels. Observe the
manufacturer's mounting instructions.
R Check the chain tension after driving
approximately 0.5 miles (1.0 km) .
i You can deactivate ASR when pulling
away with snow chains mounted.
(

Y page 49). This allows the wheels to spin
in a controlled manner, generating more
tractive force (friction effect). Tire pressure
Notes about tire pressure
G
Warning
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. Tire pressure

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. Checking the tire pressure manually
In order to determine and adjust the tire
pressures, proceed as follows:
X Remove the valve cap of the tire you wish
to check.
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 placard12


or on the tire
pressure plate on the B-pillar on the driver's
side of the vehicle.
X If necessary, increase the tire pressure to
the recommended value.
X If 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.
X Screw the valve cap onto the valve.
X Repeat the steps for the other tires. Tire pressure monitor
Important safety notes If a tire pressure monitor is installed, the
vehicle's wheels have sensors installed that
monitor the
tire

pressures in all four tires. The
tire pressure monitor warns you when the pressure drops in one or more of the tires. The
tire pressure monitor only functions if the
correct wheel electronics units are installed
in all wheels.
The tire pressure monitor has a yellow
0077
warning lamp in the instrument cluster for
indicating pressure loss/malfunctions (USA)
or pressure loss

(Canada). Depending on how
the warning lamp flashes or lights up, an
underinflated tire or a malfunction in the tire
pressure monitor is displayed:
R if the 0077 warning lamp is lit continuously,
the tire pressure on one or more tires is
significantly too low. The tire pressure
monitor is not malfunctioning.
R USA only: if the 0077 warning lamp flashes
for 60 seconds and then remains lit
constantly, the tire pressure monitor is
malfunctioning. G
Warning
Each tire, including the spare (if provided),
should be checked at least once a month
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the Tire and Loading
Information placard on the driver’s door B-
pillar or the

tire inflation 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 Information placard
or the tire inflation pressure label, you should
determine the proper tire inflation 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
pressure 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 underinflated tire causes the tire
to overheat and can lead to tire failure.
