You should always use first gear when starting
from a standing position if under heavy load or
when pulling a trailer.
Recommended Vehicle Shift Speeds
To utilize your manual transmission efficiently
for both fuel economy and performance, it
should be upshifted as listed in recommended
shift speed chart. Shift at the vehicle speeds
listed for acceleration. When heavily loaded or
pulling a trailer these recommended up-shift
speeds may not apply.

Downshifting
Moving from a high gear down to a lower gear
is recommended to preserve brakes when driv-
ing down steep hills. In addition, downshifting
at the right time provides better acceleration
when you desire to resume speed. Downshift
progressively. Do not skip gears to avoid over-
speeding the engine and clutch.
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid.
