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 40 mph
(65 km/h) with the transfer case in FOUR
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 can'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.
