SECOND (2): This position reduces vehicle speed
more than DRIVE (D) without using your brakes.
You can use SECOND (2) on hills. It can help
control your speed as you go down steep mountain
roads, but then you would also want to use your
brakes off and on.
Notice: Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph
(90 km/h) may damage the transaxle. Also,
shifting into SECOND (2) at speeds above
65 mph (105 km/h) can cause damage. Drive in
THIRD (3) or DRIVE (D) instead of SECOND (2).
Notice: If your vehicle seems to start up rather
slowly, or if it seems not to shift gears as you
go faster, something may be wrong with a
transaxle system sensor. If you drive very far
that way, your vehicle can be damaged. So, if
this happens, have your vehicle serviced right
away. Until then, you can use SECOND (2) when
you are driving less than 35 mph (55 km/h) and
THIRD (3) for higher speeds.

FIRST (1): This position reduces vehicle speed
even more than SECOND (2) without using your
brakes. You can use it on very steep hills, or in
deep snow or mud. If the shift lever is put in
FIRST (1) while the vehicle is moving forward, the
transaxle will not shift into first gear until the vehicle
is going slowly enough.
Notice: Spinning the tires or holding the
vehicle in one place on a hill using only the
accelerator pedal may damage the transaxle. If
you are stuck, do not spin the tires. When
stopping on a hill, use the brakes, or parking
brake to hold the vehicle in place.
