SRS (Supplementary Restraint System)
Your vehicle is fitted with an air bag for the driver, located in the steering
wheel, and a passenger air bag (if fitted) is located above the glove box
compartment. Airbag(s) can be identified by the “SRS AIR BAG” label on
the airbag cover.
The airbag is a supplementary restraint system and is designed to provide
effective protection to the belted occupants during frontal collisions.
The air bag system is not visible until it is activated. The activation depends
upon the severity and direction of frontal collisions. Airbags are not
designed to activate in rollover, rear and side collisions.
Operation OperationOperation Operation
Operation
Sensors in the ECU detect the frontal collision severity. The air bag(s) are
designed to deploy only if the collision matches the criteria for
deployment.
• •• •
• The sensor switches close the circuit and the propellant rapidly burns
in a container producing gases, which fill the airbag.
• •• •
• The inflating airbag deploys out of the steering wheel in the front of
the driver and passenger air bag (if fitted) deploys out of the dashboard
in front of the passenger. This action takes place in a fraction of a
second.

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.

Anti Lock Brake System (ABS) – if fitted
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.

Engine Cooling System Engine Cooling SystemEngine Cooling System Engine Cooling System
Engine Cooling System
If engine overheating occurs, there could be a fault in the
cooling system which may be on account of :
1. Less coolant in the cooling system or dirt/scale having
accumulated inside cooling water passages especially
in the radiator core.
2 . Choking of radiator passages due to foreign material or
damages.
3. Defective thermostat.
4. Defective coolant temperature sensor.
5 . Non operation of electrically operated fans (Controlled
by ECU).
6. Coolant leakage.
7. Radiator cap not sealing properly.
8 . A.C. condenser fan not working
9. Excessive refrigerant charging in the A.C. system.
10. No communication between auxiliary tank and radiator.

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.
