■Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the temperature
gauge needle comes down.

immediately stop the engine.
2. Once the engine has cooled down, inspect
the coolant level and check the cooling

If the temperature needle has gone down, resume driving. If it has not gone down,
contact a dealer for repairs.
1 How to Handle Overheating
If the coolant is leaking, contact a dealer for repairs.
Use water as an emergency/temporary measure only.
Have a dealer flush the system with proper antifreeze
as soon as possible.
3WARNING
Removing the radiator cap while the
engine is hot can cause the coolant to spray
out, seriously scalding you.
Always let the engine and radiator cool
down before removing the radiator cap.
