Earlier upshifts during cruise conditions (rela-
tively 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 trans-
mission 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 trans-
mission 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,
downshift to maintain a safe speed when de-
scending a steep grade.
WARNING!
Skipping more than one gear while down-
shifting, could cause you to lose control of
your vehicle. You could have a collision.
CAUTION!
•
If you skip more than one gear while
downshifting or downshift at too high an
engine speed, you could damage the en-
gine, transmission, or clutch.
•
Do not downshift into first gear when the
vehicle is moving faster than 15 mph (24
km/h), as you could damage the engine
and/or clutch.
