Warning!
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 engine 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.

burn if it comes into contact with hot engine
parts.
