Starting and operating
Maximum allowable speeds
The following tables show the maximum
speeds that are possible with each differ-
ent gear. The tachometer’s needle will en-
ter the red area if these speeds are ex-
ceeded.
With the exception of cases where sudden
acceleration is required, the vehicle
should not be driven with the tachometer’s
needle inside the red area. Failure to ob-
serve this precaution can lead to exces-
sive engine wear and poor fuel economy.
NOTE
Never exceed posted speed limits.
Driving tips
Do not drive with your foot resting on the
clutch pedal and do not use the clutch to
hold your vehicle at a standstill on an up-
grade. Either of those actions may cause
clutch damage.
Do not drive with your hand resting on the
shift lever. This may cause wear on the
transmission components.
When it is necessary to reduce vehicle
speed due to slow traffic, turning corners,
or driving up steep hills, downshift to a
lower gear before the engine starts to la-
bor.
On steep downgrades, downshift the
transmission to 5th, 4th, 3rd or 2nd gear
as necessary; this helps to maintain a safe
speed and to extend brake pad life.
In this way, the engine provides a braking
effect. Remember, if you “ride” (over use)
the brakes while descending a hill, they
may overheat and not work properly.
The engine may, on rare occasions, knock
when the vehicle rapidly accelerates or
rapidly pulls away from a standstill. This
phenomenon is not an indication of a
problem in your vehicle.
Gear mph (km/h)
1st 33 (53)
2nd 50 (81)
3rd 68 (110)
4th 114 (143)
When shifting down a gear, ensure
that the vehicle is not travelling at a
speed exceeding the Maximum Al-
lowable Speed for the gear which is
about to be selected. Failure to ob-
serve this precaution can lead to en-
gine 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 slippery surface can
lead to wheel locking; as a conse-
quence, control of the vehicle may
be lost and the risk of an accident in-
creased.
