Recommended Shift Points
Drive in the highest gear that lets
the engine run and accelerate
smoothly. This will give you good
fuel economy and effective
emissions control. The following
shift points are recommended:
Shift up Normal acceleration
1st to 2nd 17 mph (27 km/h)
2nd to 3rd 28 mph (45 km/h)
3rd to 4th 45 mph (72 km/h)
4th to 5th 56 mph (90 km/h)
Engine Speed Limiter
If you exceed the maximum speed
for the gear you are in, the engine
speed will enter into the tachometer's
red zone. If this occurs, you may feel
the engine cut in and out. This is
caused by a limiter in the engine's
computer controls. The engine will
run normally when you reduce the
RPM below the red zone.
Before downshifting, make sure the
engine will not go into the
tachometer's red zone.
