184 STARTING AND OPERATING
When To Use 4WD LOW — If Equipped
When off-road driving, shift to 4WD LOW for additional
traction. This range should be limited to extreme
situations such as deep snow, mud, or sand where
additional low speed pulling power is needed. Vehicle
speeds in excess of 25 mph (40 km/h) should be avoided
when in 4WD LOW.
Driving Through Water
Although your vehicle is capable of driving through water,
there are a number of precautions that must be
considered before entering the water.
NOTE:
Your vehicle is capable of water fording in up to 20 inches
(51 cm) of water, while crossing small rivers or streams. To
maintain optimal performance of your vehicle's heating
and ventilation system it is recommended to switch the
system into recirculation mode during water fording.
Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle. If you must
drive through water, try to determine the depth and the
bottom condition (and location of any obstacles) prior to
entering. Proceed with caution and maintain a steady
controlled speed less than 5 mph (8 km/h) in deep water
to minimize wave effects.
Flowing Water
If the water is swift flowing and rising (as in storm run-off),
avoid crossing until the water level recedes and/or the
flow rate is reduced. If you must cross flowing water avoid
depths in excess of 9 inches (23 cm). The flowing water
can erode the streambed, causing your vehicle to sink into
deeper water. Determine exit point(s) that are
downstream of your entry point to allow for drifting.
Standing Water
Avoid driving in standing water deeper than 24 inches
(60 cm), and reduce speed appropriately to minimize
wave effects. Maximum speed is 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine oil, transmission oil, axle,
transfer case) to ensure the fluids have not been
contaminated. Contaminated fluid (milky, foamy in
appearance) should be flushed/changed as soon as
possible to prevent component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4WD LOW if necessary
Ú page 124. Only shift into a lower gear to maintain
forward motion. Over-revving the engine can spin the
wheels and traction will be lost.
Avoid abrupt downshifts on icy or slippery roads, because
engine braking may cause skidding and loss of control.
Hill Climbing
NOTE:
Before attempting to climb a hill, determine the conditions
at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the transfer case to 4WD LOW. Use
FIRST gear and 4WD LOW for very steep hills.
If you stall or begin to lose forward motion while climbing
a steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Restart the engine, and
shift into REVERSE (R). Back slowly down the hill, allowing
the compression braking of the engine to help regulate
your speed. If the brakes are required to control vehicle
speed, apply them lightly and avoid locking or skidding the
tires.
WARNING!
Do not drive in 4WD LOW on dry pavement; driveline
damage may result. 4WD LOW locks front and rear
drivelines together and does not allow for differential
action between the front to rear driveshafts. Driving in
4WD LOW on pavement will cause driveline binding;
use only on wet or slippery surfaces.
CAUTION!
When driving through water, do not exceed 5 mph
(8 km/h). Always check water depth before entering as
a precaution, and check all fluids afterward. Driving
through water may cause damage that may not be
covered by the New Vehicle Limited Warranty.
