between gears
-
When going down a steep hill

2 (Second Gear)
This position gives you more power but lower fuel
economy. You can use "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:
Don't drive in "2"
(S
or you can damage your trans
"D or 3" as much as possible.
e
1 (First Gear)
This position gives you even more power (but lower
fuel economy) than "2." You can use it on very steep
hills, or in deep snow or mud. If the selector lever is
put in "1," the transaxle won't shift into first gear
until the vehicle is going slowly enough.
