DRIVE (D): This position is for normal driving.
If you need more power for passing, and you're:
accelerator pedal about halfway down.
Going less than about 15 mph (25 km/h), push your
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.
In this position, if the
power mode selector switch is turned to P, the
transmission will not downshift into LOW (L). See "Power
Mode Selector Switch" later in this section.
Notice: Don't shift into SECOND (2) unless you are
going slower than 63.4 mph (102 km/h) with the
transfer case in FOUR-WHEEL HIGH (4H) and
TWO-WHEEL HIGH (2H), or 34.9 mph
(56.2
km/h)
with the transfer case in FOUR-WHEEL LOW (4L).
If you move the shift lever to a lower gear while
driving faster than the maximum allowable speed for
the lower gear, the transmission will not downshift
until your speed drops below the maximum
speed for the lower gear.
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 shift
lever is put in LOW (L), the transmission won't shift
into low gear until the vehicle is going slow enough.
Notice; Don't shift into LOW (L) at speeds above
28.0 mph (45.0 km/h) with the transfer case in
FOUR-WHEEL HIGH (4H) or TWO-WHEEL HIGH (2H),
or at speeds above 15.4 mph (24.8 km/h) with the
transfer case in FOUR-WHEEL LOW (4L). If you
move the shift lever to a lower gear while driving
faster than the maximum allowable speed for
the lower gear, the transmission will not downshift
until your speed drops below the maximum
speed for the lower gear.
Notice: If your rear wheels won't turn, 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 transmission.
Also, if you stop when going uphill, don't hold your
vehicle there with only the accelerator pedal.
This could overheat and damage the transmission.
Use your brakes to hold your vehicle in position
on a hill.
