the remote control
flashes red rapidly. The remote control battery is discharged. Data transmission is not
possible.
X
Replace the remote control battery (Y page 130).The indicator lamp on
the remote control
flashes red and green in
rapid succession. There is no connection between the remote control and the
receiver in the vehicle.
X
Change your position in relation to the vehicle, e.g. hold the
remote control higher or to the side.
X Move closer.
If you cannot establish a connection and the auxiliary heating is
switched on, it can then only be deactivated using the 0084button
(Y page 124). The indicator lamp on
the remote control
flashes red and green in
rapid succession. Several remote controls are being used at the same time.
X
Switch on the remote control again after a short while
(Y page 126). The indicator lamp on
the remote control
flashes red and green in
rapid succession. The remote control is not synchronized.
X
Synchronize the remote control (Y page 126).The indicator lamp on
the remote control
slowly flashes red and
green alternately. The remote control is being synchronized.

Problem Possible causes/consequences and
0050
0050Solutions The auxiliary heating
switches off automati-
cally and/or cannot be
switched on. The low-voltage protection system integrated in the control unit
switches off the auxiliary heating because the on-board voltage is
less than 10 V.
X
Have the alternator and battery checked. The auxiliary heating
switches off automati-
cally and/or cannot be
switched on. The fuse is blown.
X
Replace the fuse; see the "Fuse allocation" supplement.
X Have the cause of the blown fuse determined at a qualified spe-
cialist workshop. The auxiliary heating
switches off automati-
cally and/or cannot be
switched on. A malfunction has occurred.
X
Switch the ignition on and off twice.
If the auxiliary heating still cannot be switched on, the heating
device is faulty.
X Have the auxiliary heating checked at a qualified specialist
workshop. The auxiliary heating is
overheated. The coolant level is too low.
X
Check the coolant level and add more coolant if necessary
(Y page 255). Operating the cargo compartment air
vents If your vehicle is equipped with a roof venti-
lator, you can ventilate and extract air from
the cargo compartment. X
Turn the key to position 2in the ignition
lock.
X To activate and extract air: press the
upper section of the 00A8switch.
The roof ventilator removes used air from
the cargo compartment.
X To activate and ventilate: press the lower
section of the 00A7switch.
The roof ventilator feeds fresh air into the
cargo compartment.
X To switch off: set the switch to the middle
position. Operating the cargo compartment air vents

!
Make sure that:
R the side windows and the roof are com-
pletely closed
R the climate control blower is switched off
R the windshield wiper switch is at position
0
The vehicle could otherwise be damaged.
You can wash the vehicle in an automatic car
wash from the very start.
Wash off excess dirt before cleaning the vehi-
cle in an automatic car wash.
After putting the vehicle through an auto-
matic car wash, wipe off wax from:
R the rear view camera lens (Y page 271)
R the windshield
R the windshield wiper blades
This will prevent smears and reduce wiping
noises caused by residue on the wind-
shield.
Washing by hand In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements for each indi-
vidual country.
X Do not use hot water and do not wash the
vehicle in direct sunlight.
X Use a soft car sponge.
X Use a mild cleaning agent, e.g. a car sham-
poo approved for use with Sprinter vehi-
cles.
X Thoroughly hose down the vehicle with a
gentle jet of water.
X Do not point the water jet directly towards
the air inlets.
X Use plenty of water and rinse out the
sponge frequently.
X Rinse the vehicle with clean water and dry
thoroughly with a chamois.
X Do not let the cleaning agents dry on the
paintwork. When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
High-pressure cleaning equipment G
WARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-
edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
! Under no circumstances use power wash-
ers in the vehicle interior. The pressurized
water and associated spray produced by
the power washer could cause extensive
damage to the vehicle.
! Observe the minimum distance to be
maintained between the nozzle of the
power washer and object to be cleaned, as
outlined below:
R approximately 2.2 ft(70 cm) when using
round-jet nozzles
R approximately 1 ft (30 cm) when using
25°flat-spray jets and dirt blasters
Keep the water jet moving while cleaning.
To avoid causing damage, do not point the
water jet directly at:
R door joints
R brake hoses
R electrical components
R electrical connections
R seals
R drive train, especially not at the inter-
mediate bearing of the propeller shaft
R rear view camera (camera lens and
microphone opening on the bottom)
Keep a minimum distance of
1.6 ft(50 cm). 268
CareMaintenance and care

Service products include the following:
R Fuels, e.g. diesel
R Additives for the exhaust gas aftertreat-
ment, e.g. Diesel Exhaust Fluid (DEF)
R Lubricants, e.g. engine oil, transmission oil
R Coolant
R Brake fluid
R Washer fluid
R Climate control system refrigerants
Approved service products comply with the
highest quality standards and are listed in the
MB Specifications for Service Products. Only
use service products approved for the vehi-
cle. This is an important condition for the war-
ranty.
You will recognize the approved service prod-
ucts by the inscription on the container: MB
Approval (e.g. MB Approval 228.5)
Other identifications and recommendations
refer to quality level or a specification accord-
ing to an MB Sheet Number (e.g. MB 228.5).
They are therefore not necessarily approved.
Further information can be obtained at any
qualified specialist workshop.
Additives for approved service products are
neither required nor permitted. Approved fuel
additives are the exception. Additives can
cause engine damage and must therefore not
be added to the service products.
The use of additives is always the responsi-
bility of the vehicle operator. The use of addi-
tives may result in the restriction or loss of
your Limited Warranty entitlements. Fuel
Important safety notes G
WARNING
Fuel is highly flammable. Improper handling
of fuel creates a risk of fire and explosion. Avoid fire, open flames, smoking and creating
sparks under all circumstances. Switch off the
engine and, if applicable, the auxiliary heating
before refueling.
G
WARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come
into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following:
R Wash away fuel from skin immediately
using soap and water.
R If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
R If fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing.
R Immediately change out of clothing which
has come into contact with fuel.
When handling, storing and disposing of fuels,
please observe the relevant regulations. Service products and capacities
