Handling the Unexpected
■Next thing to do
1.Check that the cooling fan is operating and
turn the power system off once the Stop
Driving When Safe. Engine
Temperature Too Hot message
disappears.
u If the cooling fan is not operating,
immediately turn the power system off.
2. Once the engine has cooled down, inspect
the coolant level an d check the cooling
system components for leaks.
u If the coolant level in the reserve tank is
low, add coolant until it reaches the
MAX mark.
u If there is no coolan t in the reserve tank,
check that the radiator is cool. Cover the
radiator cap with a heavy cloth and open
the cap. If necessary, add coolant up to
the base of the filler neck, and put the
cap back on.
■Last thing to do
Once the engine has cooled sufficiently, turn the power system on.
If the Stop Driving When Safe. Engine Temperature Too Hot message does not
appear, resume driving. If it appears again, contact a dealer for repairs.
1 The Stop Driving When Safe. Engine Temperature Too
Hot Message Appears on the Driver Information Interface
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.
