Driver’s A irbagThe driver’s airbag is located within the padded center
of the steering wheel.
WARNING!
If the malfunction indicator lamp1 does not
light up when the key is in position 2 in the igni-
tion lock, if it flickers or lights up while the vehi-
cle is moving, there might be a problem in the
airbag system. There is then a danger that the air-
bag will not deploy in the event of an accident or
will deploy when it should not do so. Have the ve-
hicle inspected and repaired by an authorized
Sprinter Dealer without delay.

lock, the coolant level indicator lamp
/ in the
instrument cluster lights up for about 2 seconds. It
must go out when the engine is running.
If the coolant level indicator lamp
/ remains on or lights
up again when the engine is running, the coolant level
is too low.
Do not drive on. Switch the engine off and add coolant.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.
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 2.1 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).
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.

symbol in the multi-function indicator appears
and the warning buzzer sounds, the operating
safety of the engine is endangered (possibility of

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
a danger of damage to the engine or catalytic
converter.

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 A ir 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.
