Off-Road Driving Tips
When To Use 4WD LOW Range
When off-road driving, shift to 4WD LOW for additional
traction and control on slippery or difficult terrain, ascend-
ing or descending steep hills, and to increase low-speed
pulling power (refer to “All Wheel Drive and Four-Wheel
Drive Operation” in this section for further details). 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 50 mph
(80 km/h) should be avoided when in 4WD LOW range.
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:
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.
Driving through water more than a few inches/centimeters
deep will require extra caution to ensure safety and pre-
vent 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 (22 cm). The flowing
water can erode the streambed causing your vehicle to sink
into deeper water. Determine exit point(s) that are down-
stream of your entry point to allow for drifting.
Standing Water
Avoid driving in standing water deeper than 16 inches
(40.5 cm), and reduce speed appropriately to minimize
wave effects. Maximum speed in 16 inches (40.5 cm) of
water is less than 5 mph (8 km/h).
