Towing Recommendations - PREVOST H3-45 VIP Owner's Manual

1 (First Range)
Select this range when pulling through mud and
snow, when speed control is needed for driving up or
down steep grades or when maneuvering in tight
spaces. This range also provides maximum driving
torque and engine braking power or retarder braking
effect. In the lower ranges (1, 2, 3 and 4), the
transmission will not upshift above the highest gear
selected unless engine overspeed is detected.
2 (Second Range)
Select this range when operating in heavy and
congested traffic. The transmission will start in first
and automatically upshift to second. When slowing,
the transmission will automatically downshift to first
range. Low ranges provide progressively greater
engine and retarder braking power (the lower the
range, the greater the engine and retarder braking
effect).
3, 4 (Third And Fourth Ranges)
Select these ranges when driving on moderate
grades or when load and traffic conditions limit
speed.
WARNING
Service brake should not be used to control the
speed of the vehicle on long, steep descents.
Instead, lower transmission ranges should be used
in conjunction with the output retarder. Refer to
"ENGINE BRAKE"
and"TRANSMISSION RETARDER" on page 25
Section 5 Other Features for details regarding both
systems. This procedure keeps service brake cool
and ready for emergency stopping.
CAUTION
When descending in lower ranges, care must be
taken that engine speed does not exceed 2,450
rpm.

TOWING RECOMMENDATIONS

CAUTION
When towing the vehicle, the transmission output
shaft must not be allowed to spin or turn. If the
vehicle is towed with the drive wheels still in
contact with the road surface, the vehicle axle
shafts or driveline
disconnected. Do not attempt to push or pull-start
the vehicle.
Failure to disconnect the driveshaft, remove the
drive axle shafts or lift the drive wheels off the
ground before towing will cause serious damage to
transmission.
Non-compliance with the above requirements will
void warranty.
CAUTION
Make sure axle shafts or driveshaft are installed
correctly after towing. Tighten axle shaft and
driveshaft nuts to the correct torque settings. Do
not invert shafts.
