Starting and Driving
Check List Before Moving Off
• Check that the air pressure
reading on both gauges is not
in the red sector.
• Check that the engine is idling
satisfactorily.
• See that no warning lights are
showing except the handbrake.
Starting and Driving Away
The engine can only be started with the
neutral button (N) selected. With the
vehicle standing still, the parking brake
applied, and the engine running at
idling speed, depress the footbrake
pedal and hold it down, preselect the
desired speed range, then release the
brakes and drive away by depressing
the accelerator.
If a speed range is selected with the
engine speed above 900rpm and/or
with the accelerator depressed, an
interlock in the automatic control unit
prevents a gear being selected. Only
when the engine speed is below
900rpm and the accelerator is in the
idling position is the gear selected.
Speed Ranges
The transmission will prevent a change
into any range at a speed which will
cause the engine to over speed. Any
lower range may be selected at any
time, but will only engage when the
road speed is reduced. The inhibit
effect will cause changing down to
occur at a slightly higher speeds than
normal.
CAUTION
Do not allow the vehicle to
coast in neutral. This practice
can result in severe
transmission damage. Also
no engine braking is
available.
CAUTION
Never accelerate when
operating the speed range
selector.
CAUTION
At temperatures below -23°C,
start the engine and warm up
the gearbox in neutral for
approx 10 to 15 minutes
before selecting speed range.
NOTE
The vehicle is fitted with a
Gearguard system. When selecting
a gear to move off, depress and hold
down the footbrake, then select the
gear on the selector.
