Driving
When to use 3 (Third)
3 (Third) eliminates the needless
shifting back and forth between
third and fourth gears that your
vehicle may do when driving on hilly
terrain. It also gives more engine
braking than overdrive to slow your
vehicle on downgrades.
1 (First)
Use 1 (First) for when added engine
braking is desired when descending
steep hills.
The automatic transaxle will shift to
the proper gear to ascend any grade
without any need to shift to 1
(First).
Do not go faster than 61 km/h (38 mph) when in this gear. You can
upshift from 1 (First) to overdrive at any time.
