Starting and operating
3 (Third)
This position is for using engine braking when going
down a hill or for climbing a grade.
The transmission automatically shifts into a suitable
gear from 1st to 3rd according to the vehicle speed
and the acceleration you require.
When more acceleration is required in this position,
press the accelerator pedal fully to the floor and hold
that position. The transmission will automatically
downshift to 2nd or 1st gear. When you release the
pedal, the transmission will return to the original gear
position.
2 (Second)
This position is for using engine braking when going
down a hill or for climbing a steep grade.
In this position, the transmission holds in the 2nd gear.
Use this position when starting off from a standstill on
slippery road surfaces such as mud or snow. It will en-
sure greater traction.
1 (First)
This position is for driving up or down very steep
grades, or driving through mud or sand, or on slippery
surfaces. In this position, the transmission holds in the
1st gear.

Maximum speeds
When shifting down a gear, ensure that the ve-
hicle is not travelling at a speed exceeding the
Maximum Allowable Speed for the gear which
is about to be selected. Failure to observe this
precaution can lead to engine over-revving and
this in turn can result in engine damage.
In addition, sudden application of engine
brakes when the vehicle is travelling on a slip-
pery surface can lead to wheel locking; as a
consequence, control of the vehicle may be lost
and the risk of an accident increased.
The following tables show the maximum speeds that
are possible with each different gear.
When shifting down a gear, it is important to confirm
that the current vehicle speed is not in excess of the
Maximum Allowable Speed of the gear which is about
to be selected.
