¾Ensure that fuel filter, oil filter and breather are checked
periodically and replaced, if required, as recommended
by Tata Motors.
¾Do not pour the used oils or coolants into the sewage
drains, garden soil or open streams. Dispose the used
filters and batteries in compliance with the current
legislation.
¾Do not allow unauthorised person to tamper with
engine settings or to carry modifications on the vehicle.
¾Never allow the vehicle to run out of fuel.
¾Parts like brake liners, clutch disc should be vacuum
cleaned. Do not use the compressed air for cleaning
these parts which may spread the dust in the
atmosphere.

BRAKES AND ABS (IF FITTED)
Have your vehicle attended immediately.
Put your foot on brake pedal to apply brake. Do not ride
the brakes as they may overheat and the performance may
be impaired. The brake lights may confuse the drivers
behind you.
Use engine to assist the brakes by shifting to a lower gear
and lifting your foot from accelerator pedal.
Constant application of brakes while going down the hill
builds heat and reduces braking efficiency.
Check your brakes after driving through deep water. Apply
the brakes moderately to feel that they are normal. If not,
apply them gently and frequently until they do. With wet
brakes you should be extra cautious and alert in your driving.

ABS combined with the traditional hydraulic brake system pre-
vents the wheel from locking while braking by make use of
most of road to tyre grip. It also ensures better control and
stability of car while braking.
How ABS works How ABS worksHow ABS works How ABS works
How ABS works
ABS essentially consists of an Electronic Control Unit (ECU)
which reads signals from the sensors fitted to each wheel and
identifies the one which is likely to lock. ( Wheels will tend toBrakes BrakesBrakes Brakes
Brakes
Tata Safari is equipped with ventilated disc brakes on front
and drum brakes on rear wheels.
Braking system is vacuum assisted to reduce effort needed
on the brake pedal. It is a dual circuit service brake system
designed in such a way that one circuit will always work, even
if other circuit fails.
If this happens you will immediately notice that the brake
pedal goes down much farther and you need to press the
pedal harder. In such an event the stopping distance may be
longer.
In case of failure of vacuum the vehicle can still be stopped
with a higher pedal effort.
In case of vacuum failure or brake circuit failure, slow down
the vehicle by shifting to lower gear and lifting your foot
from the accelerator pedal. Pull to the side of the road as
soon as it is safe.
CAUTION CAUTIONCAUTION CAUTION
CAUTION
Brake system failure is very hazardous. It is best to have
your vehicle towed, but if you drive the vehicle in this
condition, be extremely cautious.

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.

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.
