Recommended Shift Speeds
To utilize your manual transmission efficiently for fuel
economy, it should be upshifted as listed in recom-
mended shift speed chart.

Earlier upshifts during cruise conditions (relatively
steady speeds) may result in increased fuel economy.
Higher upshift speeds may be used to obtain a desired
acceleration rate.
NOTE:
• Your vehicle is equipped with a transmission reverse
inhibitor system. When vehicle speed is greater than
3 mph (5 km/h), the reverse inhibitor activates to help
prevent shifts into REVERSE. When at a complete
stop, you may notice lighter shift efforts into REVERSE
with the ignition key ON, as compared to the ignition
key OFF position. This is normal operation of the
transmission reverse inhibitor system.
• Due to the high performance nature of your drivetrain,
you may hear your transmission. This can be most
noticeable when the vehicle is idling in NEUTRAL
with the clutch engaged (clutch pedal released), but it
may also be heard when driving at low engine RPM.
Also, this may be more noticeable when the transmis-
sion is warm. This is a normal condition and is not an
indication of a problem with your clutch or
transmission.
