Your vehicle is equipped with the EGR ( Exhaust Gas
Recirculation) System to reduce exhaust pollution.

EGR SYSTEM :
The engine is fitted with EGR valve, EGR pipe, vacuum
modulator and associated electrical circuitry. With this,
controlled amount of exhaust gas is mixed with intake air of
the engine, in part load and speed conditions. This helps in
reducing harmful pollutants.

Tata Safari is fitted with Diesel Oxidation Catalytic Converter
to reduce exhaust pollution. The two way Catalytic
Converter has coating of precious metals which enables
conversion of pollutants.
Care of the Catalytic Converter Care of the Catalytic ConverterCare of the Catalytic Converter Care of the Catalytic Converter
Care of the Catalytic Converter
The Catalytic Converter does not require any special
maintenance however, following precautions should be
taken for the effective functioning of the converter and to
avoid damage to the converter.
1 It is mandatory to use Diesel fuel with low sulphur
content (Refer recommended fuels). Use of any other
diesel fuel can increase the pollutants.
2 Avoid parking the vehicle over inflammable materials,such as dry leaves, grass, etc., as the exhaust system
is hot enough to initiate “FIRE”.
Maintenance of Catalytic Converter Maintenance of Catalytic ConverterMaintenance of Catalytic Converter Maintenance of Catalytic Converter
Maintenance of Catalytic Converter
Catalytic Converter should be flushed by giving full throttle
(4 to 5 times) in standing condition of vehicle on daily basis.
In addition to this it is recommended to run the vehicle at
high speeds (80 to 100 kmph) for few km as this will help to
flush the carbon soot deposits from exhaust system and
catalytic converter. High speed running of the vehicle may
be done periodically to avoid chocking of catalytic converter.
Alternatively flushing operation for cleaning the catalytic
converter can be done by dry compressed air draft (3 to 4
bar) directed on the honeycomb structure of catalytic
converter (after removing from vehicle)

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 Air ConditioningAir Conditioning Air Conditioning
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.

TICE TICETICE TICE

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.

The system is charged with R 134 (a) - ‘Non C.F.C.’ refrigerant. Do
not top up with any other refrigerant.

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
