SPEED/ODOMETER
Speedometer
Speedometer mainly indicate the vehicle speed in kilometers or miles per
hour.
Odometer
The odometer records the total driving distance in kilometers or miles, and is
useful for keeping a record for maintenance intervals.
TACHOMETER
The tachometer registers the speed of your engine in revolutions per minute
(rpm). It is useful to help you shift at the appropriate engine speed to avoid
lugging or over running.
CAUTION:
The engine should not be raced to such a speed that the needle enters the red
zone on the tachometer face. This can cause severe engine damage.

WATER TEMPERATURE GAUGE
When the ignition switch is "ON", this gauge indicates the temperature of the
coolant. Under most driving conditions, the needle will remain at approximately
the halfway point. Stop and go driving, driving at high speeds during warm
weather or driving up a steep gradient may cause the pointer to move toward
the red sector. If your vehicle overheats, water lamp comes and the indicator
goes up. However when the quantity of coolant is below of the specification,
the warning buzzer will sound.
At this time, stop your vehicle immediately.
AIR PRESSURE GAUGE
The air pressure gauge indicates the air pressure in the air reservoir at all
times.
If the air pressure drops to below 6 kg/cm 2 , the air pilot light comes on and the
warning buzzer will sound at the same time. If fails to build up again, stop the
engine immediately and contact your authorized dealer.
CAUTION:
If the air pressure indicates the pressure that is below red zone do not drive the
vehicle. This is very dangerous.
