Fully press the clutch pedal before shifting gears. As you

release the clutch pedal, lightly press the accelerator

pedal.

This transmission has a “creeper” first gear (L=Low)

which should be used to start from a standing position

when carrying a payload or towing a trailer. Damage to

the clutch can result from starting in second or third gear

with a loaded vehicle. An unloaded vehicle may be

launched in second gear. Use each gear in numerical

order – do not skip a gear.

You should 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 driving 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 overspeeding the engine and clutch.
