162 Service and Maintenance

Diesel fuel filter

On each engine oil change, have the fuel
filter checked for any water residue by a
workshop.
Illumination of control indicator A in the
instrument cluster indicates water in the
diesel fuel filter.
Have fuel filter checked at shorter intervals
if the vehicle is subjected to extreme
operating conditions such as high humidity
(primarily in coastal areas), extremely high
or low outside temperatures and
substantially varying daytime and
night-time temperatures.

Coolant

The coolant provides anti-freeze
protection down to approx. -28 °C.
Caution
Only use approved anti-freeze.
Coolant additives for additional
corrosion protection and to seal minor
leaks can cause function problems. No
liability is accepted for damage caused
by the use of coolant additives.

Warning
Anti-freeze is a danger to health; it
must therefore be kept in the original
container and out of the reach of
children.
Anti-freeze and corrosion protection
Before the start of winter, have a workshop
check the anti-freeze protection. The
anti-freeze level must guarantee
protection down to approx. -28 °C.
Insufficient anti-freeze will reduce the frost
protection level and the corrosion
protection. If necessary, add anti-freeze.
If coolant loss is topped up with water,
have concentration checked and add
anti-freeze if necessary.
