MAINTENANCE & VEHICLE CARE

Catalytic Converter :
The catalytic converter is fitted on your
car to reduce exhaust pollution. The
catalytic converter will quickly heat up
after starting to ensure that it operates
correctly during the warm up phase of
the engine.
The catalytic Converter does not require
any special maintenance however,
following precaution 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
Catalytic Converter should be flushed by
giving full throttle (4 to 5 times) in standing
condition of vehicle on daily basis. For
high speed driving condition run hot 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)
CAUTION
• Avoid push start or tow-starting the
vehicle. (Use jump leads).
• Avoid long (not more than 10 sec.)
repeat (not more than 3 times)
starting of the Vehicle. Investigate
the cause for difficulty in starting &
rectify the same.
• Avoid long idling (to warm-up). If
the engine is running rough, after
a cold start.
• Avoid switching "off" the ignition
when driving down the hill. (This will
not save fuel).
• Avoid fuel tank getting almost empty.
• Avoid pre-Coating / Painting of
Catalytic Converter.
