Manual Transmission Operation

Using the Clutch
When you are starting to move the vehicle, it is
important to begin with the engine speed at idle.
Then start to engage the clutch and listen for an
engine speed drop of about 100 rpm. At this point,
the clutch is engaging, so you should increase the
engine speed and fully engage the clutch. It is
important not to increase the engine speed sooner
or before the clutch begins its engagement. If you
do, you can cause damage to your vehicle.
Double-Clutching
You must use the double-clutching method when
you shift an unsynchronized gear set. Disengage
the clutch, shift to NEUTRAL and engage the
clutch. When upshifting, slow the engine until the
engine rpm and road speed match. When
downshifting, accelerate the engine until the
engine rpm and road speed match. Then quickly
disengage the clutch and move the shift lever
to the next gear position and engage the clutch.
