The Basics Of Off-Road Driving
You will encounter many types of terrain driving
off-road. You should be familiar with the terrain
and area before proceeding. There are many
types of surface conditions: hard-packed dirt,
gravel, rocks, grass, sand, mud, snow and ice.
Every surface has a different effect on your
vehicle's steering, handling and traction.
Controlling your vehicle is one of the keys to
successful off-road driving, so always keep a
firm grip on the steering wheel and maintain a
good driving posture. Avoid sudden
accelerations, turns 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.
NOTE:
It is recommended that the Stop/Start System
be disabled during off-road use.
When To Use 4WD Low Range
When off-road driving, shift into 4WD Low for
additional traction and control on slippery or
difficult terrain, ascending or descending steep
hills, and to increase low speed 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 4WD Low.
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
Snow
In heavy snow or for additional control and
traction at slower speeds, shift the transmission
into a low gear and the transfer case into 4WD
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 lost. If you start to slow to a
stop, try turning your steering wheel no more
than a 1/4 turn quickly back and forth, while
WARNING!
Always wear your seat belt and firmly tie down
cargo. Unsecured cargo can become projec-
tiles in an off-road situation.
CAUTION!
Never park your vehicle over dry grass or
other combustible materials. The heat from
your vehicle exhaust system could cause a
fire.
CAUTION!
Do not use 4WD Low when operating the
vehicle on dry pavement. Driveline hardware
damage can result.
