208 Service and maintenance

aging control, whereas viscosity

grade gives information on the oil's

thickness over a temperature range.

Dexos is the newest engine oil quality

that provides optimum protection for

gasoline and diesel engines. If it is

unavailable, engine oils of other listed

qualities have to be used.

Recommendations for gasoline

engines are also valid for

Compressed Natural Gas (CNG),

Liquified Petroleum Gas (LPG) and

Ethanol (E85) fuelled engines.

Select the appropriate engine oil

based on its quality and on the

minimum ambient temperature

3 212.

Topping up engine oil

Engine oils of different manufacturers

and brands can be mixed as long as

they comply with the required engine

oil quality and viscosity.

Use of engine oil with only

ACEA A1/B1 or only A5/B5 quality is

prohibited, since it can cause long-

term engine damage under certain

operating conditions.

Select the appropriate engine oil

based on its quality and on the

minimum ambient temperature

3 212.

Additional engine oil additives

The use of additional engine oil

additives could cause damage and

invalidate the warranty.

Engine oil viscosity grades

The SAE viscosity grade gives

information of the thickness of the oil.

Multigrade oil is indicated by two

figures, e.g. SAE 5W-30. The first

figure, followed by a W, indicates the

low temperature viscosity and the

second figure the high temperature

viscosity.

Select the appropriate viscosity grade

depending on the minimum ambient

temperature 3 212.

All of the recommended viscosity

grades are suitable for high ambient

temperatures.

Coolant and antifreeze

Use only silicate-free long life coolant

(LLC) antifreeze.

The system is factory filled with

coolant designed for excellent

corrosion protection and frost

protection down to approx. -28 °C.

This concentration should be

maintained all year round. The use of

additional coolant additives that

intend to give additional corrosion

protection or seal against minor leaks

can cause function problems. Liability

for consequences resulting from the

use of additional coolant additives will

be rejected.

Brake and clutch fluid

Only use high-performance brake

fluid approved for the vehicle, consult

a workshop.

Over time, brake fluid absorbs

moisture which will reduce braking

effectiveness. The brake fluid should

therefore be replaced at the specified

interval.
