Operation and Driving Tips

Proper manual transmission operation ensures longevity and optimal performance.

Starting: Depress clutch fully, shift to 1st gear, apply throttle while releasing clutch smoothly.
Shifting: Always depress clutch fully before changing gears. Avoid forcing shifts.
Rev Matching: For smoother downshifts, blip throttle while shifting to match engine and transmission speeds.
Hill Starts: Use parking brake on steep inclines to prevent rollback.
Reverse Gear: Come to complete stop before engaging. May require slight forward movement if resistant.

WARNING! Never rest hand on shift lever while driving as this can cause premature wear.
