1.5L REVOTORQ ENGINE 76 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.
