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.
