[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.

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
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.
