268 STARTING AND OPERATING
good driving posture. Avoid sudden accelera-
tions, 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 4L (Low) Range
When off-road driving, shift into 4L (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 situa-
tions 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.
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 pres-
sure 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 trac-
tion 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 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
still applying throttle. This will allow the tires to
get a fresh "bite" and help maintain your
momentum.
Mud
Deep mud creates a great deal of suction
around the tires and is very difficult to get
through. You should use DRIVE, with the
transfer case in the 4L (Low) position to main-
tain your momentum. If you start to slow to a
stop, try turning your steering wheel no more
WARNING!
Always wear your seat belt and firmly tie down
cargo. Unsecured cargo can become
projectiles 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 4L (Low) range when operating
the vehicle on dry pavement. Driveline
hardware damage can result.
CAUTION!
On icy or slippery roads, do not downshift at
high engine RPM or vehicle speeds, because
engine braking may cause skidding and loss
of control.
