Auto Retard Speed Control (ARSC)
ARSC allows the operator to simply set the downhill travel
speed and go down slopes at a constant speed. This allows
the operator to concentrate on steering. The speed can be
set at increments of 1 km/h
0.6 MPH
per click
(±5 km/h
3.1 MPH
of setting speed adjustment) to match
the optimum speed for the slope. The retarder cooling oil
temperature is constantly monitored and the descent speed
is automatically reduced, if necessary.

Automatic Idling Setting System (AISS)
This system facilitates quick engine warm-up and cab
cooling/warming. When setting the system ON,
engine idle speed is kept at 1000 rpm when
coolant temperature is 30°C
86°F
or lower.
Speed automatically returns to 650 rpm when
coolant temperature goes above 30°C
86°F
.
Small Turning Radius
The MacPherson strut type front suspension has a special
A-frame between each wheel and
the main frame. The wider
space created between the
front wheels and the main
frame increases the
turning angle of the
wheels. The larger this
turning angle, the smaller
the turning radius of the truck.
