Warning | 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. | |
Warning | 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. | |

| Check | ||
1 | Unscrew cap (1) on expansion reservoir (2) | ||
2 | Check coolant level | Check and correct the coolant level only when the coolant temperature is between 0 °C and 20 °C. | |
3 | Check anticorrosion/antifreeze protection | To do so, drain coolant from radiator drain screw if required. | |

With insufficient corrosion and antifreeze protection: | |||
| |||
Correct corrosion and antifreeze protection - subject to separate repair order. | |||
Correcting anticorrosion/antifreeze concentration | |||
4 | Correct coolant level; to do so, fill coolant up to "MAX" mark | Use only coolant of the specified composition. | |
