lock, the fuel filter indicator lamp in the
instrument cluster lights up for about 7 seconds. It
must go out when the engine is running.
If water in fuel indicator lamp does not go out or
comes on with the engine running, drain the water
from the fuel filter as soon as possible. NOTE: Should the water in fuel indicator lamp
still not go out after the fuel filter has been drained, the
cause should be examined by an authorized Sprinter
Dealer.
If the indicator lamp does not light up for about
7 seconds with the key in the ignition lock in position 2,
there is a malfunction in the water separator system.
Have the cause rectified by an authorized Sprinter

Engine Oil Level Indicator LampThe engine oil level indicator lamp: lights up in
the instrument cluster when the key is turned to
position 2 in the ignition lock. It must go out when the
engine is running.If the engine oil level indicator lamp: does not go
out, or if it lights up again while the vehicle is moving,
the engine oil level has dropped to a point close to the
minimum level mark on the dipstick.
The indicator lamp: lights up only briefly at first,
becoming permanent as the oil level drops further.
Stop the engine immediately and check the engine oil
level. If no obvious leak is visible, correct the oil level.
If the engine oil level indicator lamp: lights up,
even if the engine oil level is sufficient, have the cause
traced and rectified by an authorized Sprinter Dealer.

98 UNDERSTANDING YOUR INSTRUMENT PANELCoolant Level Indicator LampWhen the key is turned to position 2 in the ignition
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.

104 UNDERSTANDING YOUR INSTRUMENT PANELDepending on the driving style, the mileage covered
and the operating conditions, the next service due is
displayed either as a remaining distance in "mi"
(in km) or as a remaining time in "days". The length of
time between services should not exceed 2 years.
The display will be cancelled when the
button (‘) is pressed, or automatically after
10 seconds.
When a service has been performed, have the ASSYST
maintenance computer reset by an authorized Sprinter
Dealer.
Should your Sprinter for any reason not be serviced by
an authorized Sprinter Dealer, the ASSYST
maintenance computer can, in exceptional
circumstances, be reset as follows:
Turn the key to position 2 in the ignition lock and
immediately press the button (‘) twice.
Within 10 seconds, return the key to position 0 in the
ignition lock.
Press and hold the button (‘). Turn the key to
position 2 in the ignition lock. Keep the
button (‘) pressed.The maintenance indicator with the current remaining
time/distance is shown.
After about 10 seconds, an acoustic signal will sound
and the maintenance indicator is displayed with the
new remaining time/distance.
Release the button (‘).
NOTE:
The ASSYST maintenance computer provides
information on the optimum maintenance requirements.
If maintenance intervals are not observed, resulting
damage will not be covered by Warranty.
The ASSYST maintenance computer is not an engine
oil gauge.
Engine oil level – for display in instrument cluster, see
next page.
If the engine oil level indicator lamp lights up, refer to
"Engine Oil Level Indicator Lamp".
If the battery is disconnected, the time is not recorded
by the ASSYST maintenance computer. Such periods
must be considered if maintenance intervals are
measured by time.

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.

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
a danger of damage to the engine or catalytic
converter.
