If engine power drops and the needle on the engine coolant temperature gauge goes
up above the upper limit of the safety zone and enters the "H" zone, the engine is
overheating. The engine overheat warning light will come on and the warning buzzer
will sound. Take the following corrective actions immediately.
Engine overheat warning light
WARNING
• When the engine coolant is still hot, do not remove the sub-tank cap. Hot vapor
will come out and you may be scalded. The engine coolant in the sub-tank will
be hot, which may also cause scalding. Perform all checks, replenishment and
change when the engine coolant temperature has lowered.
• When you must unavoidably remove the sub-tank cap, wait until the temperature
drops to the suitable level of 80°C (176°F), cover the cap with a thick cloth,
press the pressure release button, and slowly loosen the cap.
• Do not drink the engine coolant, as it is toxic. If engine coolant gets in your eyes,
rinse them immediately.
• Engine coolant is flammable, and therefore, it must be kept away from flames
and other heat sources.
IN CASE OF EMERGENCY
When the Engine Overheats
1. Operate the hazard warning
flasher switch and pull the vehicle
immediately over to a safe place
that doesn't impede traffic (shoulder,
verge) and park it.
2. Keep the engine speed of 1,000 r/min
and cool down the engine for a while
before turning it off.
ADVICE
• Do not stop the engine immediately.
Otherwise, the engine may seize.
3. When the needle of the engine
coolant temperature gauge returns to
the middle of the safety zone, stop the
engine.
