Driving off-road with 4WD
Your vehicle is specially equipped
for driving on sand, snow, mud and
rough terrain and has operating
characteristics that are somewhat
different from conventional
vehicles, both on and off the road.
The following information will help
you learn to properly use 4WD.
When using 4WD, maintain
steering wheel control at all times,
especially in rough terrain. Since
sudden changes in terrain can
result in abrupt steering wheel
motion, make sure you grip the
steering wheel from the outside.
Do not grip the spokes.
Drive cautiously to avoid vehicle
damage from concealed objects
such as rocks and stumps.
You should either know the terrain
or examine maps of the area
before driving. Map out your route
before driving in the area. For
more information on driving
off-road, read the ªFour Wheelingº

Automotive fluids are not
interchangeable; do not use engine
coolant, antifreeze or windshield
washer fluid outside of its specified
function and vehicle location.
Adding engine coolant
Do not put engine coolant
in the container for the
windshield washer fluid.
If sprayed on the windshield,
engine coolant could make it
difficult to see through the
windshield.
When the engine is cool, add a
50/50 mixture of engine coolant
and water to the engine coolant
recovery reservoir-DO NOT ADD
DIRECTLY TO THE RADIATOR.
Add straight water only in an
emergency, but you should replace
it with a 50/50 mixture of coolant
and distilled water as soon as
possible.
Check the coolant level in the
coolant recovery reservoir the next
few times you drive the vehicle. If
necessary, add enough of a 50/50
mixture of coolant and water to
bring the liquid level to the fill line
on the reservoir.
Never remove the coolant
recovery cap while the
engine is running or hot.
If you must remove the coolant
recovery cap, follow these steps to
avoid personal injury:
