the driver about the upshift timing.
The shift-up indicator can be activated or
deactivated. For details, refer to Shift-up
indicator (STI) 3-31.
Maximum allowable speeds
The following table shows the maximum
speeds that are possible with each differ-
ent gear. The tachometer s needle will
enter the red area if these speeds are
exceeded.
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
observe this precaution can lead to
excessive engine wear and poor fuel
economy.

WARNING
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
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 slippery surface can
lead to wheel locking; as a conse-
quence, control of the vehicle may
be lost and the risk of an accident
increased.
NOTE
Never exceed the posted speed limit.

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
upgrade. Either of those actions may
Except STI
mph (km/h)
cause clutch damage.
Do not drive with your hand resting on the
31 (49)
shift lever. This may cause wear on the
55 (88)
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
labor.
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.
