has not gone down, contact a dealer for repairs.

Steam and spray from an overheated engine can seriously scald you.
Do not open the hood if steam is coming out.

spray out, seriously scalding you.
Always let the engine and radiator cool down before removing the radiator
cap.
NOTICE
Continuing to drive with the temperature gauge pointer at the H mark may
damage the engine.

Emergency Engine Stop*

The ENGINE START/STOP button may be used to stop the engine due to an
emergency situation even while driving. If you must stop the engine, choose
one of the following operations:
• Press and hold the ENGINE START/
STOP button for two seconds, or
• Firmly press the ENGINE START/
STOP button three times.
The steering wheel will not lock.
However, because turning off the
power system disables the power
assist the power system provides to
the steering and braking systems, it
will require significantly more physical
effort and time to steer and slow the
vehicle. Use both feet on the brake
pedal to slow down the vehicle and stop immediately in a safe place. With
manual transmission models you can also downshift the transmission to utilize
engine braking.
