Power to the road wheels is transferred via mechanical units called as auto‐locking hubs. When 4WD
is selected the auto‐locking hubs lock the axle shaft to the wheel hub. This mechanical locking will
occur when the vehicle is driven in either forward or reverse direction. In case the mode is shifted to
2WD, the vehicle has to driven in either forward or reverse direction for few feet. Disengagement of
the auto‐locking hubs can be identified by clicking sound from the units.
4H ‐ Four Wheel High
All four wheels are driven at 1:1 speed ratio. The
four wheel drive lamp illuminates when 4H mode
is selected. This mode provides additional
traction and maximum pulling power for loose,
slippery road surfaces such as ice, snow, gravel,
sand and dry pavement. Front and rear drive
shafts are locked together in this mode which
forces the front and rear wheels to rotate at the
same speed.
4L ‐ Four Wheel Low
All four wheels are driven at 2.48:1 speed ratio.
Use this mode for maximum pulling power and
traction. Use 4L position for climbing or
descending steep hills, off
‐road driving, hard
pulling in sand, mud or deep snow. Driving in the
4L position on dry hard surfaced roads may cause
increased tire wear and damage to driveline
components. Front and rear drive shafts are
locked together in this mode which forces the
front and rear wheels to rotate at the same
speed. Take care not to over rev the engine and
do not exceed 20 mph when driving in this mode.
When operating your vehicle in 4L, the engine
speed is considerably higher than that of the 4H
position at a given road speed.
Because four‐wheel drive provides improved traction, there is a tendency to exceed safe turning and
stopping speeds. Do not go faster than the permitted road conditions. Do not shift to a lower gear
than necessary to maintain forward motion. Over‐revving the engine can spin the wheels and traction
will be lost. Avoid abrupt down shifts on slippery roads, engine braking may cause skidding and loss of
control.
