AUTOMATIC OVERDRIVE (
B): This position is
for normal driving. If you need more power for passing,
and you’re:
D Going less than approximately 35 mph (55 km/h),
push your accelerator pedal about halfway down.
D Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You’ll shift down to the next gear and have more power.
THIRD (3): This position is also used for normal
driving, however, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (
B). Here
are some times you might choose THIRD (3) instead of
AUTOMATIC OVERDRIVE (
B):
D when driving on hilly, winding roads,
D when towing a trailer, so there is less shifting
between gears, or
D when going down a steep hill.
SECOND (2): This position gives you more power but
lower fuel economy than AUTOMATIC OVERDRIVE
(
B) or THIRD (3). 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.
FIRST (1): This position gives you even more power
but lower fuel economy than SECOND (2). You can
use it on very steep hills, or in deep snow or mud. If
the selector lever is put in FIRST (1), the transaxle
won’t shift into FIRST (1) until the vehicle is going
slowly enough.
NOTICE:
If your front wheels can’t rotate, don’t try to
drive. This might happen if you were stuck in
very deep sand or mud or were up against a solid
object. You could damage your transaxle.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transaxle. Use your brakes or shift into PARK (P)
to hold your vehicle in position on a hill.
Selectable Shift
This button lets you change from a normal driving mode
to a power mode. For general driving conditions, use the
normal mode.
