or braking. In most cases, there are no road signs, posted
speed limits or signal lights. Therefore, you will need to use
your own good judgment on what is safe and what is not.
When on a trail, you should always be looking ahead for
surface obstacles and changes in terrain. The key is to plan
your future driving route while remembering what you are
currently driving over.
CAUTION!
Never park your vehicle over dry grass or other com-
bustible materials. The heat from your vehicle exhaust
system could cause a fire.
WARNING!
Always wear your seat belt and firmly tie down cargo.
Unsecured cargo can become projectiles in an off-road
situation.
When To Use 4L (Low) Range
When off-road driving, shift into 4L (Low) for additional
traction and control on slippery or difficult terrain, ascend-

pulling power. This range should be limited to extreme
situations such as deep snow, mud, steep inclines, 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 4L (Low) range.
CAUTION!
Do not use 4L (Low) range when operating the vehicle
on dry pavement. Driveline hardware damage can
result.
Simultaneous Brake And Throttle Operation
Many off-road driving conditions require the simultaneous
use of the brake and throttle (two-footed driving). When
climbing rocks, logs, or other stepped objects, using light
brake pressure with light throttle will keep the vehicle from
jerking or lurching. This technique is also used when you
need to stop and restart a vehicle on a steep incline.
Driving In Snow, Mud And Sand

In heavy snow or for additional control and traction at
slower speeds, shift the transmission into a low gear and
the transfer case into 4L (Low) if necessary. Do not shift to
a lower gear than necessary to maintain headway. Over-
revving the engine can spin the wheels and traction will be
