The tachometer is a useful gauge when attempting to drive efficiently. It will let you match driving speed and gear selection to the operating range of your engine. If the engine speed gets too high, you can select a higher gear to lower the RPM's. If the engine speed drops too low, you can select a lower gear to raise the RPM's. (Refer to Driving Tips and Techniques on page 4-44 for further instructions on driving techniques and using the tachometer.) To avoid engine damage, do not let the pointer exceed maximum governed speed. (See your Engine

• Never downshift when the vehicle is moving too fast. • Never slam or jerk the shift lever to complete gear engagement. • Never coast with the transmission in neutral and the clutch disengaged. • To provide smooth gear engagements while shifting, use proper coordination between 4 shift lever and clutch.

Double clutching is a very effective means to increase the service life of your transmission. Double clutching refers to a technique where the clutch pedal is used twice per shift instead of once. It also requires that you adjust the engine rpm in the middle of the shift which ultimately synchronizes the gears during shifting. Synchronizing reduces wear on the gears.
