AUTOMATIC OVERDRIVE (D): This position is for
normal driving. If you need more power for passing, and
you are:
•
Going less than 35 mph (55 km/h), push your
accelerator pedal about halfway down.
•
Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You will shift down to the next gear and have
more power.
Notice: If your vehicle seems to start up rather
slowly or not shift gears when you go faster, and
you continue to drive your vehicle that way, you
could damage the transaxle. Have your vehicle
serviced right away. You can drive in LOW (L) when
you are driving less than 35 mph (55 km/h) and
AUTOMATIC OVERDRIVE (D) for higher speeds
until then.
THIRD (3): This position is also used for normal driving.
However, it offers more power and lower fuel economy
than AUTOMATIC OVERDRIVE (D). Here are some
times you might choose THIRD (3) instead of
AUTOMATIC OVERDRIVE (D):
•
When driving on hilly, winding roads.
•
When towing a trailer, so there is less shifting
between gears.
•
When going down a steep hill.
2-26
LOW (L): This position gives you more power but lower
fuel economy than THIRD (3). You can use LOW (L)
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.
You can use LOW (L) on very steep hills, or in deep
snow or mud. If the shift lever is put in LOW (L),
the transaxle will not shift into first gear until the vehicle
is going slowly enough.
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
LOW (L) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or AUTOMATIC
OVERDRIVE (D) instead of LOW (L).
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 to hold the vehicle in place.
