Dial description
Water temperature meter
The water temperature meter is used to indicate the temperature of the
engine coolant. The temperature of the coolant will change because of the
temperature of the atmosphere and vehicle running condition. If the indication
of the meter is over its normal range, stop the vehicle as soon as possible.
Under the condition of too hot engine, continuously drive the vehicle will
cause the damages of the engine.
Fuel meter
The fuel meter is used to indicate the fuel level in the tank. The indica-
tion may change slightly because of braking, turning, or accelerating of the
vehicle. Please fill the fuel tank in time before the fuel is used up.
