5. DRAINING AND FILLING

5.1 TOPPING UP BATTERY FLUID 

Avoid sparks and open flames in the 

vicinity of batteries.

Battery acid is an aggressive fluid.

In the event of contact with the skin: 

rinse the skin with plenty of water for 

a sustained period. If redness or 

pain persists, consult a doctor. 

Remove any clothing affected and 

rinse with water.

In the event of contact with the eyes: 

rinse with plenty of water for at least 

15 minutes and consult a doctor.

If swallowed: do NOT induce 

vomiting. Rinse the mouth, drink two 

glasses of water and consult a 

doctor.

In the event of inhalation: get fresh 

air, rest and consult a doctor.

Topping up battery fluid 
1.

Clean the top of the battery. If the top of the 

battery has acid on it, it should be rinsed with 

water.

2.

Remove the plugs and top up the batteries 

with distilled water to approximately 10 mm 

above the plates or up to the "max" indicator 

level.

unnecessary contact with the 

drained oil

Draining the engine oil
1.

Ensure that the vehicle is standing on a flat 

and level surface. 

2.

Drain the engine oil at operating temperature 

using the drain plug in the oil sump.

3.

Replace the drain plug sealing ring and 

tighten the drain plug to the specified torque, 

see main group "Technical data". 

Filling the engine oil
1.

Fill the engine through oil-filler pipe (C) with

5.3 DRAINING AND FILLING, COOLING SYSTEM

When the coolant is hot, there is an 

overpressure in the cooling system. 

Carefully remove the filler cap to 

release the overpressure.

Do not remove the filler cap when the 

engine is running.

Coolant is a toxic fluid. Contact with 

the skin should therefore be 

avoided.

In the event of contact with the skin: 

remove the liquid with paper or a 

cloth, wash with soap and water. If 

irritation persists, consult a doctor.

If swallowed: DO NOT induce 

vomiting. Rinse mouth, drink two 

glasses of water and consult a 

doctor.

In the event of inhalation: get fresh 

air and rest.

In order to avoid damaging the 

cylinder block, do not top up a warm 

engine with coolant.

Draining the cooling system
1.

Turn the heater control knob to the maximum 

"hot" temperature setting. As a result, the 

heater valve will be fully opened.

2.

Remove the cooling system filler cap.

3.

Collect the coolant. Position suitable 

containers under the drain points.

4.

Drain the cooling system at the cylinder 

block via the drain cock (A) and the radiator 

via the drain plug (B). If an integrated 

retarder is fitted, remove the coolant drain 

plug of the heat exchanger. 

5.

Flush the cooling system.

6.

Close the drain cock (A) and fit the drain plug 

(B) and, if applicable, the coolant drain plug 

of the heat exchanger of the integrated 

retarder.

Filling/bleeding the cooling system
1.

Turn the heater temperature control knob in 

the cab to the maximum "hot" setting. 

2.

Fill the cooling system with the specified 

coolant up to the fill opening of the expansion 

tank. 

3.

Start the engine and continue to top up the 

cooling system. 

4.

The cooling system is auto-bleeding. 

Bleeding will be audible during topping up. 

Continue topping up until bleeding is no 

longer audible. 

5.

Close the cooling system and allow the 

engine to warm up until the thermostat has 

opened. 

6.

Stop the engine and check the fluid level on 

the transparent rear side of the expansion 

tank; add more coolant if necessary. 

If the vehicle is fitted with water cab heater
1.

Run the engine at idling speed. 

2.
