DRIVE (D): This position is for normal driving.
If you need more power for passing, and you're:
Going less than about
15 mph (25 km/h), push
your accelerator pedal about halfway down.
Going about
15
mph (25 km/h) or more, push your
accelerator pedal all the way down.
You'll shift down to the next gear and have
more power.
SECOND (2): This position gives you more power but
lower fuel economy. 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:
Don't shift into SECOND (2) unless you are going
slower than 65 mph (105 k m h ) with the transfer
case in FOUR HIGH (4H), or 35 mph (55 km/h)
with the transfer case in FOUR LOW (4L) or you
can damage your transmission.
LOW (L): 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 LOW (L), the transmission
won't shift into low gear until the vehicle is going
slowly enough.
I
NOTICE:
Don't shift into LOW (L) at speeds above
40 mph (65 kmh) with the transfer case in
FOUR-WHEEL LOW
(4L),
or you can damage
your transmission.
