Operation (cont.)
ROAD SPEED LIMITING (RSL)
RSL is an optional feature that limits the top vehicle speed the
ECM allows. RSL is set to one of the following two positions:
•
OFF
•
Vehicle speed to be determined by customer, up to a
maximum of 204 kph (127 mph).
To have the RSL set, changed, or turned off, see an authorized
service provider.
ROAD OPERATION
Correct road operation of your vehicle will provide the following:
•
Satisfactory engine performance
•
Maximum fuel economy
•
Long service life
General guidelines for correct road operation
1.
Use the lowest gear to get the vehicle moving. This allows
the engine to more easily move the load.
2.
Accelerate smoothly and evenly to engine’s rated speed.
Rapid acceleration causes high fuel consumption.
3.
To prevent lugging, do not allow engine speed to drop below
1,200 rpm during full throttle.
4.
When approaching a hill, press accelerator smoothly to start
the upgrade at full power. Downshift to maintain maximum
vehicle speed.
DOWNHILL OPERATION
CAUTION:
To prevent engine damage when driving downhill, do
not operate the engine above high idle.
Protect your engine when driving downhill as follows:
•
Prevent overspeeding of engine when going down long and
steep grades.
•
Operate the engine closest to high idle for maximum retarder
system operation.
•
See
Vehicle Operator Manual
for engine retarder system
operation procedures.
