GAUGE DISPLAY
ENGINE COOLANT TEMPERATURE GAUGE
Engine coolant temperature gauge displays the engine coolant
temperature in 19 graduations.
When the graduation of gauge is in green range (B) during op-
erations, it is normal.
When the graduation of gauge is in red range (A) during opera-
tions, the overheat prevention system is actuated, and engine
coolant temperature caution lamp (D) lights up in red.
Red range: Abnormal
The overheat prevention system is actuated.
Graduation of gauge lights up in red.
Engine coolant temperature caution lamp (D) lights up in red.
Green range: Normal
Graduation of gauge lights up in green.
Engine coolant temperature caution lamp (D) lights up in blue.
White range: Low temperature
Graduation of gauge lights up in white.
When the graduation of gauge goes beyond white range (C), color changes to green.
Engine coolant temperature caution lamp (D) lights up in white.
OFF: Abnormal
If communication error occurs or data is not received, the graduation of gauge goes out.
REMARK
• The overheat prevention system is actuated when the graduation of gauge goes in red range (A).
The engine runs at low idle.
Engine coolant temperature caution lamp (D) lights up in red.
The alarm buzzer sounds.
It keeps sounding until the graduation of gauge goes in green range (B).
• When starting the engine, if the engine coolant temperature gauge is in white range (C) and engine coolant
temperature caution lamp (D) lights up in white, the engine coolant temperature is low. Accordingly, perform
the warm-up operation.
FUEL GAUGE
Fuel gauge displays the fuel level in 19 graduations.
When the graduation of gauge is in green range (A) during op-
erations, it is normal.
When the graduation of gauge goes in red range (B) during op-
erations, the remaining fuel level is 20 ℓ or less, so check the
fuel level and add it.
(A) Green range: Normal
The remaining fuel level is above 20 ℓ.
Fuel level caution lamp (C) lights up in blue.
(B) Red range: The remaining fuel level is low
The remaining fuel level is 20 ℓ or less.
Fuel level caution lamp (C) lights up in red.
OFF: Abnormal
If communication error occurs or data is not received, the graduation of gauge goes out.
