Warning! 1 In order to avoid possible serious burns or injury: • Use extreme caution when opening the hood if there are any signs of steam or coolant leaking from the cooling system, or if the coolant temperature gauge indicates that the coolant is overheated. • Do not remove pressure cap on coolant reservoir if engine temperature is above 194°F (90°C). Allow engine to cool down before removing cap. The coolant reservoir contains hot fluid and is under pressure. • Using a rag, slowly open cap approximately 1/2 turn to relieve excess pressure. If opened immediately, scalding hot fluid and steam will be blown out under pressure. • Do not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes into contact with hot engine parts. To check the coolant level, the vehicle must be parked on level ground and the engine stopped. Check coolant level only when coolant is cold. The coolant level should reach the COLD LEVEL mark in the reservoir. Anticorrosion/antifreeze mixture, see page 366. After adding coolant, close cap until you hear it click a few times.
