Steering SteeringSteering Steering
Steering (Ensure that Power Steering fluid reservoir is totally
clean before starting the work)
1 . Fill the reservoir nearly full. Crank the engine for 10
seconds without allowing it to start (if possible). If engine
does start, shut the engine immediately. Check & refill
the reservoir repeat atleast three times, each time
checking & refilling the reservoir.
2 . Check for leakage in the system and if noticed take
corrective action.
3 . Start the engine and steer the vehicle from full left to full
right turns 3-4 times.
4 . Add fluid if necessary to maintain the level upto filter top.
NOTICE NOTICENOTICE NOTICE
NOTICE
Do not force the wheel against lock position either
extreme left or right. The power steering pump may get
damaged. Hold it lightly.
5 . When the engine is at steady speed, check for bubble
or foaming in the oil. If present it indicates that air is
getting sucked into the systems. Check the suction
line/fittings and correct if necessary.
6 . Once the system is bled properly and free from foaming
there should not be any appreciable change in oil level
in the reservoir, when the engine is started or stopped
repeatedly.
7 . Now the system is ready for driving.
Final oil level should be at ‘H’ mark on dip stick.
NOTICE NOTICENOTICE NOTICE
NOTICE
* Do not allow fluid level to drop significantly or run out
of the reservoir during the above operation. This may
induce air to the system.
* Do not start the engine without oil in the power steering
system. This will result in serious damage to the
pump. In case of emergency disconnect the pump belt
and then start the engine.
* Always use recommended oil from closed containers.
Any dirty oil poured in the system will result in damage
to pump and gear box.

A load conscious pressure reducing valve eliminates the
possibility of rear wheels from locking and achieves optimum
braking in any load condition of the vehicle.
The valve, is fitted on RH long member connecting it to rear
axle through its link and control spring.
If any, alteration is done in rear suspension, the performance
of this valve will be impaired.

The by-pass valve is provided in the rear brake circuit between
tandem master cylinder and ABS unit. The by-pass valve
bypasses the ABS unit in rear only braking (i.e. front brake
failed) condition. The feedback of front line pressure is
provided to the by-pass valve. in case of front brake failure,
the low front line presure being sensed by the by-pass valve
and the 100% brake line pressure from tandem master
cylinder is applied on to the rear brakes without reduction
in pressure.

ECU :
DICOR engine common rail system consists of ECU, sensors
and actuators. The Electronic control unit (ECU) is a 32 bit
microprocessor which controls the injection parameters as well
as some of the vehicle related outputs. The ECU receives input
from various sensors located on the engine and the vehicle to
decide the injected quantity and injection timing best suited
for the engine to work with maximum efficiency and safety.
ECU is fitted inside the engine compartment.

* The battery gives off explosive gases during normal operation.
A spark or open flame can cause the battery to explode causing
very serious injuries.
* Keep all sparks & open flames and smoking materials away from
the battery.
* Getting electrolyte in your eyes or skin can cause severe burns.
Wear protective clothing and a face shield or let a skilled
technician do the battery maintenance.
* Battery contains sulphuric acid (electrolyte) which is poisonous
and highly corrosive in nature.
1. Check the battery for electrolyte level with marked lines on the
battery outer case.
2. Check Battery terminals for corrosion (a white or yellowish
powder). To remove it, cover the terminals with solution of baking
soda. It will bubble up and turn brown.
When this stops, wash it off with plain water. Dry off the battery with
a cloth or paper towel. Coat the terminal with Petroleum Jelly to
prevent future corrosion.

Maintaining the car when not in extended use :
Park the car in covered, dry and if possible well-ventilated
premises.
Engage a gear.
Remove the cables from the battery terminals (first remove
the cable from the negative terminal).
Make sure the handbrake is not engaged.
Clean and protect the painted parts using protective wax.
Clean and protect the shiny metal parts using commercially
available special compounds.
Sprinkle talcum powder on the rubber windscreen wiper and
rear window wiper blades and lift them off the glass.
Slightly open the windows.
Cover the car with a cloth or perforated plastic sheet. Do
not use sheets of imperforated plastic as they do not allow
moisture on the car body to evaporate.
Inflate the tyres to 0.5 bar above the normal specified
pressure and check it at regular intervals.
Check the battery charge every six weeks.
Do not drain the engine cooling system.

All the electrical circuits in your vehicle have fuses to protect them
from a short circuit or overload. These fuses are located in 2 fuse boxes.
The interior fuse box is below the dash board on driver’s side. Remove
the fuse box lid by grabbing and pulling down the slot.
The under bonnet fuse box is located in engine compartment on LHS.

Checking and Replacing Fuses
If any electrical unit in your vehicle has stopped functioning, the fuses
should be checked first.
1. Turn the ignition key to lock position.
2. Remove the cover of the fuse box.
3. Check each fuse and look for burnt wire inside the fuse. If it is burnt,
replace it with one of the spare fuses of same rating or lower.
4. If the replacement fuse of same rating burns out in short time, there
is probably a serious electrical problem. Get the vehicle attended at
nearest Authorised Workshop.

Your vehicle is fitted with a turbocharger having variable
turbine technology ( VTT ). Turbocharger is an efficient
supercharging device used in our engine. It makes optimal
use of thermal energy of engine exhaust gases to run a
turbine which in turn drives a compressor to force air under
pressure into the inlet manifold. This turbocharger is
optimized for higher power output flat torque across large
engine speed range and better fuel consumption.

The turbocharger rotor assembly is supported by two fully
floating bearing bushes in the bearing housing. These
bearing bushes are lubricated with finely filtered engine
oil from the lubrication system of the engine.
Idle the engine for a while (30 seconds) after starting the
engine and before stopping the engine to ensure adequate
lubricating oil supply to the turbocharger.

All turbocharger connections must be leak-proof. Check air
inlet, air outlet, exhaust gas inlet and exhaust outlet
connections as well as oil inlet and outlet connections to
the turbocharger and tighten the connections where
required.Proper maintenance of air filter, oil filter as well as use of
correct grade of oil and adherence to oil change intervals is
essential for proper functioning of the turbocharger.
If you suspect any malfunctioning of the turbocharger, take
the vehicle to the nearest dealer. Do not remove the
turbocharger yourself.

Air Conditioning
The Air Conditioning is a sealed system. Any major maintenance
should be done by Authorised Workshop.
There are couple of things which can be done by you to ensure proper
working of Air conditioning / Heating.
Periodically check the engine’s radiator and air conditioning
condensers for leaves, insects and dirt stuck in front surface.
These block the air flow and reduce the cooling efficiency. Use a light
water spray from a hose or a soft brush to remove them.

Use only low pressure spray or soft bristle brush to clean condenser
and radiator fins.
Run the air conditioning at least once a week during winter season.
Run it at least for ten minutes with vehicle at steady speed and engine
at normal operating condition. This circulates lubrication oil in the
compressor.
For any complaint on A.C. and Heating get it attended at Authorised
Workshop.

Check the conditions of belts on the engine. Examine the edge of
the belt for cracks or fraying.
Check the tension of the belt by pushing on it with your thumb for
Alternator belt and A.C. compressor belt and Power Steering belt
as shown in schematic diagram.
The belts should have deflection of 4 to 6 mm.
If the belt tension is not proper, get it attended at the nearest
authorised service outlet.
Correct tension of the belt is very critical from belt life and belt
noise point of view. It is recommended that belt tension should be
measured with clavis gauge to ensure recommended values as given
below
