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.

Wheel Alignment
Correct wheel alignment helps to decrease tyre wear. You
should get your vehicle’s wheel alignment checked regularly.
In case uneven tyre wear is observed, vehicle’s wheel alignment
should be checked as soon as possible.
Wheel Balancing Wheel BalancingWheel Balancing Wheel Balancing
Wheel Balancing
Wheels are balanced at the factory. They may need to be
rebalanced at some time before they are worn out. The wheels
should be checked for balance if tyre or tube is repaired.
Whenever a tyre or wheel rim is changed tyre needs to be
balanced.
1. Permissible imbalance for tyre with rim = 250 gm-cm (max.)
2. Total balance weight should be within 140 gms on each
side.
3. Relocate the tyre if the weight required to balance is more
than 140 gm.
4. Balance weights are available from 10 gm to 80 gm, 90 gm
to 140 gm & 15 gm to 135 gm in steps of 10 gms.
5. Do not use more than one balance weight on one side.T TT T

Check for the inflation and condition of your TATA SAFARI tyres
periodically.
Inflation InflationInflation Inflation
Inflation
Check the pressure in the tyres when they are cold.
Refer to tyre information label fitted on fuel flap inside for
correct cold tyre pressure.
You should have your own tyre pressure gauge and use it
all times. This makes easier for you to tell if pressure loss
is caused by a tyre problem and not by variation between
gauges.
Keeping the tyres properly inflated gives you the best
combination of riding comfort. handling and tyre life.
Over inflation of tyres makes the vehicle ride bumpy and
harsh. Tyres are more prone to uneven wear and damage
from road hazards.
Under inflated tyres reduce your comfort in vehicle handling
and are prone to failures due to high temperature. They
also cause uneven wear.

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)

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
