Thus unnecessary spinning of one wheel is avoided and torque
is transmitted to both wheels, thus assisting the vehicle to traverse
loose terrain. However during normal driving, the differential
action takes place in the same manner as in a standard differential.

Four Wheel Drive Operation Four Wheel Drive OperationFour Wheel Drive Operation Four Wheel Drive Operation
Four Wheel Drive Operation
In 2-H mode, only the rear two wheels of the vehicle are
powered by the engine and the front wheels are merely
pushed. By shifting to four wheel drive mode (4H or 4L)
the rear as well as the front axles get geared to the engine
through transfer case and transmit the engine power to all
four wheels. This gives the vehicle increased traction.
In 4H mode, the transmitted engine torque and vehicle
speed remain the same as in 2H. However, when you shift
to 4L mode engine torque is multiplied and vehicle moves
at low speed in the same gears with increased traction. 4L
mode is provided for negotiating sharp gradients or driving
through loose soil/sand.

Free Wheeling of Front Hub
After shifting from 4H to 2H, for effecting free wheeling of front
wheels, direction of vehicle motion needs to be changed. If
the vehicle was moving forward in 4H then bring it to halt and
engage reverse gear of main gear box. (If it was moving reverse
in 4H mode then stop it, and then engage forward gear of
main gear box.) After stopping and changing the gear the
vehicle must travel in opposite direction for a minimum of three
meters, before free wheeling takes place.

Do not engage four wheel drive mode (4H or 4L)
continuously on dry and hard road surface. It can cause
expensive damage to the vehicle transmission and the
tyres.
Four wheel drive facility is a powerful tool which enables
the vehicle to traverse terrain which is otherwise
inaccessible to two wheel drive vehicles. However, it must
be used judiciously and carefully. Do not take unnecessary
risks and attempt the impossible. Familiarise yourself
thoroughly with the vehicle and its abilities before
attempting serious off road driving.
With ignition ‘ON’ 4H & 4L indicator lamp on panel should
glow for a few seconds only & then go off. Continuous
illumination of 4L & 4H lamps indicates electrical fault.

Set the selector knob to 4H position. Gently release the clutch
and apply the accelerator for a smooth start and to avoid wheel
spin.
CAUTION CAUTIONCAUTION CAUTION
CAUTION
Use of snow tyres and / or tyre chain is recommended.
Maintain a safe distance between vehicles to avoid sudden
braking and slow down by shifting down the gears.
Avoid sudden acceleration, braking or turning. Such sharp
manoeuvers can cause loss of traction and thereby loss of vehicle
control.
Driving on Sandy or Muddy Roads Driving on Sandy or Muddy RoadsDriving on Sandy or Muddy Roads Driving on Sandy or Muddy Roads
Driving on Sandy or Muddy Roads
In case the traction on the wheels is sufficient, you may be
able to proceed in 4H mode. However in case change in
road conditions are anticipated, it is better to select the 4L
mode. Shift the selector knob to 4L position by following
the correct procedure and proceed in the normal manner.
Your vehicle will move at a slower pace with higher engine
RPM in the same gear because of the 4L mode. To match
your power and speed requirements, you can shift up in
any of the 5 forward gears or the reverse gear.NOTICE NOTICENOTICE NOTICE
NOTICE
You may choose to reduce the tyre pressure marginally for
additional grip on loose surfaces, though with a slight loss of
ground clearance.
•Try to maintain a constant engine speed and avoid sudden
acceleration which can cause wheel spin and loss of traction,
possibly leading to bogging down of the vehicle.
•If the vehicle gets stuck in loose sand, do not keep on
accelerating as the wheel spin will only result in the
wheels sinking deeper.
•The extent of muddy / sandy, conditions and the traction
available is difficult to judge and the vehicle can get
bogged down deeply. Operation should be done at slow
speed only. If possible, get down and check the path
conditions before proceeding.

•Never venture to drive through water when it flows over guard stones.
•Engine may get seriously damaged if attempted to cross over through deep water.
•If at all the situation demands that you have to drive through water then;
- Keep engine in fast idling and crawl the vehicle in low gear.
- After driving through water apply brakes several times to dry liners and to regain
original braking.

•Dip the head lamp for oncoming traffic during night driving.
•Maintain a speed such that you can stop within illuminated distance of head lamps.
•Use head lamp main/dip beam to alert other road users on turns/cross roads etc.
•Use side indicators for lane change or turning.
•Put on hazard warning switch in case of hazardous parking or if your vehicle is disabled
to warn the passing traffic.

Climbing Sharp Gradients on Loose Surfaces
•Select the 4L mode, start off smoothly in any suitable gear. Apply power smoothly so
that there is no loss of traction by over-revving of the engine.
•Choose as smooth a slope as possible and select the appropriate gear so that gear
changing in the middle of the climb is not required.
Changing gears in the middle of the climb can cause loss of momentum and engine
stalling. Shifting to lower gear has to be done cautiously to avoid loss of traction.
•Under no conditions should the vehicle be moved diagonally across a hill. The danger
is in loss of traction and sideways slippage, possibly resulting in tipping over. If
unavoidable, choose as mild an angle as possible and keep the vehicle moving.
•If the wheels start to slip within few feet of the end of the climb, motion can be
maintained by swinging the steered wheels left and right, thereby providing increased
grip.
•If the vehicle stalls or losses headway while climbing a steep hill, make a quick shift to
reverse and allow the vehicle to move back with the control of engine compression.

•Select the 4L mode and depending on the severity of the gradient, shift into

•Brake application under such situations should be done very smoothly to avoid loss of

Select appropriate gear so that gear changing or clutch disengagement is not involved
while descending the gradient.

•For towing the vehicle, the best way is to use a recovery van.
•Alternatively use a rigid tow bar.
•Avoid using flexible cable or rope as your vehicle may crash into towing vehicle when
it stops suddenly.
•Switch ‘ON’ Hazard warning switch to warn the other road users.
•Keep the engine in idling so that power steering assistance is available. This will also
built the vacuum for the brakes.
•In case of brake failure, use parking brake to control the vehicle.

Fuel
High speed diesel conforming to IS 1460 or EN 590 or equivalent
is recommended to be used as fuel.
At very low temperatures fluidity of diesel may become
insufficient due to paraffin separation. It is therefore, necessary
to mix supplementary fuel with summer or winter grade diesel.
The supplementary fuel to be used is kerosene or aviation
turbine fuel.
Ratios for mixing of supplementary fuel and diesel are shown
