 Danger !

Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running.

Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.

AS00.00-Z-0005-01A

 Danger !

Risk of injury to skin and eyes suffering scalding from contact with hot coolantspray. Risk of poisoning from swallowing coolant.

Do not open cooling system unless coolant temperature is below 90 °C. Open cap slowly and release the pressure. Do not pour coolant into beverage containers.
Wear protective gloves, protective clothing and safety glasses.

Check

1

Unscrew cap (1) from filler neck (2) of cooling system

2

Check coolant level

 Only check and correct the coolant level at a coolant temperature below 50°C.
The cooling system is correctly filled when the coolant is visible in the filler neck (2).
Before adjusting coolant to correct level, inspect anticorrosion/antifreeze protection.

3

Inspect anticorrosion/antifreeze protection

 To do so, drain coolant from radiator drain screw if required.
