2H (2-Wheel High): This setting is for driving in most street and highway
situations. Your front axle
is not
engaged in two-wheel drive.
4H (&Wheel High): This setting engages your front axle to help drive your
vehicle. Use 4H when you need extra traction, such as on wet or icy roads,
or in most off-road
situations.
N
(Neutral): Shift to this setting only when your vehicle needs to be towed
or when using a power take-off.
4L (4-Wheel Low): This setting also engages your front axle to give you
extra power, but should be used only for off-road driving.
You can shift from 2H to 4H or from 4H to 2H while the vehicle is moving.
Your front axle will engage faster if you take your foot off of the accelerator
for a few seconds after you shift. In extremely cold weather it may be
necessary to stop or slow the vehicle to shift out of 2H.

Remember that driving in 4H or 4L may reduce fuel economy. Also, driving
in four-wheel drive on dry pavement could cause your tires to wear faster
and make your transfer case harder to shift.
Front Axle Locking Feature
The front axle locks and unlocks automatically when you shift the transfer
case. Some delay for the axle to lock or unlock is normal. If the outside
temperature is very hot, or the vehicle has been used under hard driving
conditions, there may be a slight delay for the axle to unlock.
