Depending 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.

Hydraulic Brake System, Clutch Mechanism Fluid
Level
1. Brake fluid reservoir
Brake fluid level must be between the MIN and MAX
marks in the reservoir (1).
If the brake fluid is below the MIN mark, there may be
a fault in the hydraulic system. Have the system
checked as soon as possible by an authorized Sprinter
Dealer.Brake fluid
Refer to the "Recommended Fluids" chart later in this
section for recommended brake fluids.
In the course of its service life, the boiling point of the
brake fluid will fall due to the continuous absorption of
moisture from the atmosphere.
If the brakes are placed under heavy loads (e.g., on
steep hills) bubbles of steam can then form in the brake
system.
This will adversely affect the brakes' effectiveness.
Engine Cooling System
The use of aluminum components in Sprinter engines
requires that anticorrosive/antifreeze specifically
formulated to protect aluminum parts be used. The
factory approved Service Products are suitable for
Sprinter engines and can be mixed with the original
anticorrosion/antifreeze filled in at factory.
Cooling system design and anticorrosion/antifreeze
agent used stipulate the replacement interval for the
coolant solution in your vehicle. Please observe the
replacement interval specified in the Service Booklet
for your vehicle.
262 MAINTAINING YOUR VEHICLE
Failure to use MB 325.0 anticorrosion/antifreeze and/or
equivalent to DaimlerChrysler material standard MS-
9769 and/or adhere to the specified replacement interval
may result in a significantly shortened service life.
For coolant composition and water quality, contact
your authorized Sprinter Dealer.
Engine Coolant
The coolant is a mixture of water and a corrosion
inhibitor/antifreeze additive. Within the cooling
system, the corrosion inhibitor/antifreeze ensures
anti-corrosion protection
antifreeze protection
a higher boiling point.
The coolant added in the factory ensures adequate
antifreeze and anti-corrosion protection.
Refer to the "Recommended Fluids" chart for coolant
recommendations.
For reasons of anti-corrosion protection and to increase
the boiling point, the coolant added to the cooling
system is designed for all year round operation – even
in countries with high prevailing temperatures.Have the coolant renewed at least every 15 years or
after 160,000 miles.
When the coolant is renewed, the new coolant should
contain 50% antifreeze/corrosion inhibitor by volume.
This corresponds to antifreeze protection down to -
37 °C/-35°F.
Do not exceed a proportion of about 55 % by volume
(antifreeze protection down to about -45 °C/-49 °F) as
the heat dissipation properties then deteriorate.
In the event of coolant loss, do not add water only, but
sufficient antifreeze/corrosion inhibitor to maintain
the correct concentration.
The water in the coolant must satisfy certain
requirements. These are often met by tap supply
drinking water.
The water must be specially prepared if the water
quality does not come up to the required standards.
Have the corrosion inhibitor/antifreeze concentration
in the coolant checked at the outset of winter,
respectively once a year in countries with high
prevailing temperatures.

Recommended Fluids and Lubricants
The manufacturer recommends for your vehicle model
the use of DaimlerChrysler approved fluids and
lubricants, e.g. engine oil, gear oil, automatic
transmission fluid, brake fluid, power steering fluid,
coolant and anti-corrosion/anti-freeze fluid only.
WARNING!
Failure to use fluids and lubricants which meet
the standards and specifications described in this
booklet or failure to adhere to the specified re-
placement intervals may result in damage to safe-
ty-related systems of your vehicle, such as the
brake system, which could cause an accident and/
or serious injury to you and others.
Use only fluids and lubricants meeting the
standards and specifications and adhere to
specified replacement intervals.
CAUTION!
Failure to use fluids and lubricants which meet
the standards and specifications described in this
booklet or failure to adhere to the specified
replacement intervals may result in a significantly
shortened service life and/or damage to
components of your vehicle, the repair of which
will not be covered by Warranty.
Use only fluids and lubricants meeting the
standards and specifications and adhere to
specified replacement intervals.
