268 STARTING AND OPERATING 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 switch in the ON position (RUN position for Keyless Enter-N-Go) as compared to the LOCK position (OFF position for Keyless Enter-N-Go). This is normal operation of the transmission reverse inhibitor system. with the clutch engaged (clutch pedal released), but it may also be heard when driving at low engine RPM.
