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.
1–4 Skip Shift
There are times when you must shift the transmission
directly from first gear to fourth gear instead of from first
gear to second gear. This is to help you get the best
possible fuel economy from your vehicle. This occurs
when the engine coolant (antifreeze) is higher than 106°F
(41°C), vehicle speed is greater than 19 mph (30 km/h)
but less than 21 mph (34 km/h), and the transmission is
in first gear, and the accelerator is at ¼ throttle or less.
After you shift the transmission to fourth gear, you can
press the clutch in and shift to another forward gear.
Downshifting
To maintain a safe speed and prolong brake life, down-
shift to maintain a safe speed when descending a steep
grade.
