IMPORTANT INFORMATION
Appropriate Gearshifts
ADVICE
Downshifts are performed for two •
main purposes:
For engine braking on a steep -
and/or long downward slope
For responsiveness and economy -
on an uphill slope
[Cautions for downshifts]
Allowing the engine to overrun can •
result in engine damage. Do not
allow the engine to overrun when
downshifting.
Driving uphill
•
Downshift early to avoid heavy
engine load.
Driving downhill
•
In principle, you should use the
same gear(s) that you used to
drive up the hill. Drive at a speed
that does not cause the engine to
overrun (exceed its r/min limit) and
the tachometer needle to enter the
red zone.
NOTE
[What is engine brake?]
Engine brake is the braking effect that occurs when you release the accelerator •
pedal while driving. The lower the gear, the stronger the engine brake.
Drive at a speed that does not cause the
tachometer needle to enter the red zone.
Tachometer → Refer to page 4-11
