ASSYST, the A
ctive S
ervice Syst
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

avoiding short journeys where
the engine does not reach the op-
erating temperature

Dirty or iced-up steps and entrances cre-
ate a risk of slipping or falling.
Keep steps, entrances and footwear free
from dirt (e.g. mud, clay, snow and ice).
!
CAUTION
Do not allow water to enter the in-
take and ventilation openings.
When cleaning with high-pressure
water or steam cleaners, the spray
must not be aimed directly at electri-
cal components or at the end of elec-
trical lines.
Treat the engine with preservative
agents after cleaning. Protect the
belt drive system from the preserva-
tive when you do so.

CAUTION
Do not use any acidic or alkaline
cleaning agents. They can cause cor-
rosion of the wheel bolts (wheel
nuts) or the balancing weight retain-
ers.

The coolant temperature gauge is above
250°F (+120°C).
The coolant is too hot and the engine is not be-
ing sufficiently cooled.
\1Park your vehicle in a safe location as
quickly as possible and let the engine
continue to run at idle speed for about
1 to 2 minutes before switching it off.
This allows the coolant temperature to
return to normal again.
If the coolant temperature is still too high:
\1Switch off the engine and let it as well
as the coolant cool down.
\1Check the coolant level and observe the
warning notes as you do so
(\2page 329).
\1Add coolant as necessary.
