PRECAUTIONS
WARNING
To avoid thermal injury, do not touch exhaust
system when the system is hot. Any service
on the exhaust system should be performed
when the system is cool.
At every interval of periodic maintenance service
and when vehicle is raised for other service, check
exhaust system as follows:
Check rubber mountings for damage,
deterioration or out of position.
Keep sufficient clearance between exhaust
system components and underbody.
Check exhaust system for leakage, loose
connection, dent and damage. If bolts or nuts
are loosened, tighten them to the specified
torque.
Check nearby body areas for damage, missing
or mis-positioned part, open seam, hole, loose
connection or any other defect which could
permit exhaust fumes to seep into vehicle.
PRECAUTIONS FOR CATALYTIC CONVERTER
In the event of following symptoms, drive the vehicle
at slow speed without rapid acceleration.
Engine misfires or runs irregularly, following a
cold start.
A significant loss of power is noticed.
In case MIL lamp remains ON even after
engine has been started.
MAINTENANCE
OF
CLOSE
COUPLED
CATALYTIC CONVERTER
Close Coupled 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 close coupled catalytic
converter. High speed running of the vehiclemay be
done periodically to avoid chocking of Close
Coupled Catalytic Converter.
AVOID
Push start or tow-starting the vehicle. (Use
jump leads)
Long (not more than 10 seconds) repeat (not
more than 3 times) starting of vehicle.
Investigate the cause for difficulty in starting
and rectify the same.
Long idling (to warm-up) if the engine is
running rough, after a cold start.
Switching "OFF" the ignition when driving
down the hill.
Fuel almost empty.
Pre-Coating/Painting of catalytic converter.
WARNING
Parking Warning
Avoid parking of vehicle over inflammable
materials, such as dry leaves; grass etc. as
exhaust system is hot enough to initiate fire.
CAUTION
Ensure exhaust system and catalytic
converter is not blocked and is free from
obstruction.
Blockages in the exhaust can create back
pressure, low top speed, poor pick up, black
smoke, carbon build up and low mileage.
Check and ensure EGR Valve & control
system is clean and functioning properly.
Excessive carbon build-up / sticky valve.
Damaged vacuum lines.
All these can keep the ‘EGR’ open when not desired
and vice versa. Either way these can seriously
affect power output of the engine and also the
emission levels.
CAUTION
The Catalytic converter should not be
dropped from a height. If dropped, it should
not be used.
