If the vehicle is equipped with an auxiliary
battery in the engine compartment, it is
necessary to disconnect both batteries
when working on the vehicle electrical
system. Only then is the electrical system
fully disconnected from the power supply.
iOnly disconnect the vehicle electrical
system from the power supply using
the battery isolating switch if the ve-
hicle is to be parked up for a long pe-
riod or when this is absolutely
necessary.
After the power supply is switched
on, you must reset the electric sliding
door (

Unique identifier which facilitates efforts
by tire manufacturers to notify purchas-
ers in recall situations or other safety
matters concerning tires and gives pur-

tires. The TIN is comprised of the “man-
ufacturer’s identification mark”, “tire
size”, “tire type code” and “date of man-
ufacture”.

\3 Winter drivingHave your vehicle winterproofed at the
onset of winter at an authorized Sprinter
Dealer. This service includes the follow-
ing:\4
Oil change, if the current engine oil
used has not been approved for win-
ter use
\4
The antifreeze / anti-corrosion con-
centration in the coolant is checked
\4
The addition of a concentrated
cleaning agent to the water in the
windshield washer system
\4
Battery check
\4
A tire changeYou will find information about diesel
fuel for use at low outside temperatures
in the “Technical data” section
(
\2
page 614).
Please also observe the information
about winter driving (
\2
page 406).
Winter tires should also be operated as
printed on the tire and loading informa-
tion placard
1 or on the tire inflation pres-
sure placard located on the driver’s door
B-pillar, refer to “Tires and wheels” (
\2
page 362). Not all M+S rated radial-
ply tires provide special winter perfor-
mance. Make sure the tires you use
show M+S and the mountain/snowflake
marking
.
on the tire side wall.
These tires meet specific snow traction
performance requirements of the Rub-
ber Manufacturers Association (RMA)
and the Rubber Association of Canada
(RAC) and have been designed specifi-
cally for use in snow conditions. Use of
winter tires is the only way to achieve
the maximum effectiveness of the ABS,
BAS, ASR and ESP
® in winter operation.

ASSYST, the A

em, in-
forms you when the next service is due.
A service that is due is displayed about a
month or 1900 miles (3000 km) in ad-
vance. A message is then displayed
while the vehicle is in motion or the igni-
tion is switched on.
Active Service System (ASSYST)*
!
CAUTION
Periods when the battery is discon-
nected will not be recorded by AS-
SYST. To make sure that you have
the vehicle serviced at the correct
time, you should therefore subtract
periods when the battery is discon-
nected from the days shown.
The service indicator does not pro-
vide information about the engine oil
level. The service indicator should
not, therefore, be confused with
theP
engine oil level display.
iThe service due date is displayed in
days or miles (kilometers), depend-
ing on the total distance driven.
The time between the individual ser-
vice due dates depends on your style
of driving. You can increase this by:\4
driving with care and at a moder-
ate engine speed
\4
avoiding short journeys where
the engine does not reach the op-
erating temperature
