1.5L REVOTORQ ENGINE 71 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 LNT+DPF 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. 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 LNT+DPF should not be dropped from a height. If dropped, it should not be used. DPF cleaning procedure by air: If DPF soot accumulation too high, fault (P24A4 -00) is triggered and DPF regeneration not getting triggered using service tool. (Label name: Relative soot accumulation based on diff pressure; value should be more than 150%). Remove LNT DPF and blow less than 2 bar air from tail pipe end to clean the LNT DPF. After blowing air for 2 min approximately, refit LNT DPF. After refitting, run the vehicle, check for exhaust gas leakage near LNT DPF area and follow service regeneration procedure. Precaution: High black soot particles expected to come out of LNT inlet, sufficient precautions to be taken to avoid inhaling of smoke.
