If a large quantity of coolant is being lost, or if smaller
amounts are lost at regular intervals, have the engine
cooling system examined by an authorized Sprinter
Dealer.Engine Control Unit Indicator Lamp
When the key is in position 2 in the ignition lock, the
engine control unit indicator lamp± will light up in
the instrument cluster. It must go out when the engine
is running.
If the engine control unit indicator lamp± remains on
or lights up again while the vehicle is moving, the fuel tank
was run empty or a fault has developed in the engine
control unit. The engine’s power output may be reduced.
Refuel and bleed the fuel system or have the cause
traced and rectified by an authorized Sprinter Dealer.
CAUTION!
Never run the engine if the coolant level is too
low. This could cause the engine to overheat,
leading in turn to engine damage.
WARNING!
Driving when your engine is badly overheated
can cause some fluids which may have leaked into
the engine compartment to catch fire. You could
be seriously burned. Steam from an overheated
engine can cause serious burns and can occur just
by opening the engine hood. Stay away from the
engine if you see or hear steam coming from it.
Turn off the engine, get out of the vehicle and do
not stand near the vehicle until it cool downs.

Engine Oil Level – Display in Instrument Cluster
(Vehicles with ASSYST Maintenance Computer only)
If the : indicator lamp lights up briefly when the
engine is running, the engine oil level has dropped to
the minimum mark. Check the engine oil level without
delay and add oil to the upper mark on the dipstick. If no engine oil is added and the engine oil level drops
further, a warning buzzer will also sound and
will appear in the multi-function indicator. 2.0 quarts
(about 1.9 liters) of oil must be added.
NOTE: Engine oil level display
– "qt" in USA only.
– "l" in Canada only.
CAUTION!
If the : indicator lamp lights up, the warning
symbol in the multi-function indicator appears
and the warning buzzer sounds, the operating
safety of the engine is endangered (possibility of
engine damage).
A sudden decrease or absence of oil pressure may
indicate a mechanical failure. Bring the vehicle to
a safe stop, and investigate the cause to prevent
further damage. Do not operate the engine until
the cause has been determined and corrected.

NOTE: If the oil level is correct and a fault warning is
still given, have the fault traced and rectified by an
authorized Sprinter Dealer.Displaying Engine Oil Level with Engine Off
If the engine has reached normal operating
temperature, the engine oil level can be displayed on
the multi-function indicator for about 5 minutes after
the engine has been switched off.
The vehicle must be standing on a level surface when
the engine oil is being checked.
Turn the key to position 2 in the ignition lock and wait
about 10 seconds until the multi-function indicator
shows the : symbol.
CAUTION!
Do not operate the engine if the oil level is above
maximum. There is a danger of damage to the
engine or catalytic converter.

Briefly press button (1) twice within 1 second.
The following displays can then appear in the multi-
function indicator:
It is not necessary to add
engine oil.
1 quart (about 1 liter) of
engine oil must be added.
1.5 quarts (about 1.4 liters)
of engine oil must be
added.
2 quarts (about 1.9 liters) of
engine oil must be added.
Excess engine oil must be
drained or siphoned off.
NOTE: Engine oil level display

– "l" in Canada only.
NOTE: If the engine oil level is correct and a warning
that the engine oil level is too high or too low is still
given, have the fault traced and rectified by an
authorized Sprinter Dealer.
If it is not possible to measure the engine oil level
correctly, the È symbol will flash in the multi-
function indicator – repeat the measurement after
waiting a short time.
If no engine oil level reading is shown again, the engine
oil level can still be checked with the dipstick.
Consult an authorized Sprinter Dealer to have the
system checked. Symb

If the : indicator lamp lights up when the engine is
running, the engine oil level has dropped to the
minimum mark. Check the engine oil level without

If there is no engine oil in the oil sump, a warning
buzzer will sound if the key is turned to position 2 in

the warning
will appear in the multi-function indicator. About 2
quarts (1.9 liters) of oil must be added.

CAUTION!
If the : indicator lamp lights up, the warning
symbol in the multi-function indicator appears
and the warning buzzer sounds, the operating
safety of the engine is endangered (possibility of
engine damage).
Safely pull off the road and turn off the engine (do
not restart the engine). Determine the cause of the
problem. If there are no obvious signs of leakage,
add engine oil. The engine oil level must be
between the lower and upper marks on the
dipstick. Only add engine oil up to the upper
mark – do not overfill.
If the engine oil level is above maximum, there is

To switch on:
Press switch (1), the indicator lamp (2) in the switch
lights up.
To switch off:
Press switch (1) again, the indicator lamp (2) goes out.
NOTE: Run the air conditioning at least once a month
for about 10 minutes.
It is possible that the air conditioning will
automatically switch off at outside temperatures below
41 °F (+5 °C). Dehumidification is then also not
possible.
Condensation may emerge from the underside of the
vehicle.
The air conditioner only uses the refrigerant R-134a.
This refrigerant does not damage the earth’s ozone
layer.Climate Control (on Vehicles with Air Conditioning)
1. Set the airflow control (2) to position 1 to 4.
Position 4 gives maximum cooling.
2. Set the temperature switch (1) as required (The
interior temperature is regulated by the
Tempmatik. If the interior temperature falls below
the preset temperature, warm air is automatically
supplied).
3. Set the air distribution control (3) to h.
4. To switch on air conditioning, press switch (4).
WARNING!
While driving, deactivate the air conditioning
only temporarily to prevent window fogging.

AUXILIARY HEATER – WATER OR AIR HEATER
(OPTIONAL)
NOTE: The auxiliary heater (water or air heating
device) can be used whether or not the engine is
running.
After you have filled your vehicle’s gas tank with
winterized diesel fuel for the first time, it is
recommended that you operate the auxiliary heater
before beginning a journey or operating the heater
continuously so that any summer diesel fuel left in the
auxiliary heater can combust.
Before switching the auxiliary heater on make sure that
that the battery is sufficiently charged and that there is
enough fuel in the tank. At least a quarter of the tank
should be filled up. See Fuel Gauge.
WARNING!
The auxiliary heating must not be operated at gas
stations due to the risk of fire and explosion. For
this reason, switch off the auxiliary heating before
refuelling.
Auxiliary heaters emit fumes when in operation,
including carbon monoxide.
Inhaling carbon monoxide is a health hazard and
can result in unconsciousness and death.
For this reason, do not operate auxiliary heating in
enclosed spaces without ventilation or an
extractor system, e.g. in a garage. Otherwise you
could endanger yourself and others.
Always keep the ground under the vehicle as clear
as possible so that the auxiliary heater can receive
enough combustion air and exhaust fumes can
escape. Otherwise you could endanger yourself
and others.
WARNING!
Vehicles for transporting hazardous goods:
Observe the relevant safety regulations.
