NOTE: If the shift selector lever will not move
with the key on and the brake pedal
depressed refer to Shift lock system in
the Index.
Once the gearshift is secure in the desired
position, release the brake pedal and use the
accelerator as necessary.
Backing Up
With the gearshift in the R (Reverse) position,
the vehicle will move backward. You should
always come to a complete stop before shifting
into or out of R (Reverse).
Driving
When to use Overdrive (D with Overdrive
activated)
Overdrive is the usual driving position for an
automatic overdrive transaxle. It works the same
way Drive (Overdrive OFF) works, automatically
upshifting or downshifting as the vehicle speeds
or slows.
However, Overdrive also shifts into a fourth
gear — an overdrive gear — when your vehicle
cruises at a consistent speed for any length of
time. This fourth gear will increase your fuel
economy when you travel at cruising speeds.
Overdrive may not be appropriate for certain
terrain. If the transaxle shifts back and forth
between third and fourth gears while you are
driving on hilly roads, select Drive (Overdrive
OFF) by cancelling Overdrive as outlined below.
