When red bulb is glowing, it indicates that gas pr. is very low, Take the vehicle to filling station for filling the gas. • Check pressure of CNG in high pressure gauge. - If the readings of gas pr. line after parking at night and before starting g in the morning g are different,, it indicates leakage. • Check gas leak indicator for leakage indication indication. • Check engine compartment, Receptacle and y valve area for any y leakage g 3-way Tips for the Driver – Before Starting the Engine • Get the leakage location identified and stopped. • Check and ensure that the Receptacle cap and Three way valve are intact and functional. • Check Pressure of Low pressure gauge. If it is in red zone, get the HPR checked. • Check coolant level, top up if necessary. Rectify, if any coolant leakage is there. • Check lube oil level in Engine and Transmission, top up if necessary. Rectify if any lube oil leakage is there. Rectify, there Tips for the Driver – Before Starting the Engine • • • • Check Service indicator for Red band. If red band appears, get the air filter replaced. Check previous day’s Complaint Ensure that all the access flaps at rear and side of the bus body are securely closed and locked locked. All the inspection windows on the bus floor are closed and locked. • Check for any type of leakages. • Check tyre condition and tyre pressure. • Check suspension system. • Check Wind-screen glass and other glasses. • Check Safety items like fire extinguisher, window breaking hammer, roof exit window and roof top ladder. • Check door operation, Horn, Destination board, Head lights, parking lights, roof lights, fog lights, blinkers, brake lights, indicators, passenger seats, Rear view mirrors, Dash board switches, gauges, meters, • Check the contents of the first aid box.

Tips for the Driver – While Starting the Engine / Vehicle While starting the engine / vehicle: • Ensure parking g brake is applied and locked properly. y • Fasten the Seat belt. Insert belt tongue into buckle. A position locking 'click' indicates correct assembly. • Move gear shift selector to ‘N’ ( Neutral ) position and see that ‘N’ appears on the display screen Tips for the Driver – While Starting the Engine / Vehicle • Insert ignition key to unlock the steering wheel and switch on and check the following: • • • • • • • • Check gas leak indicator for any leakage. Check CNG pressure indicator. DC-DC fault indicator Engine stop indicator and Engine warning indicator. Check Engine oil level indicator Check Coolant level indicator. ABS warning lamp comes ‘ON’ ON and goes ’OFF’ OFF . Check Transmission Light is ‘ON”. • Turn the key clockwise to ‘Start’ position to crank the engine. Check Transmission Light should go ‘OFF’ when the engine is started started. This ensures that the Transmission system is free from errors / trouble codes. Tips for the Driver – While Starting the Engine / Vehicle • Idle the engine for at least 3 minutes. • Check air pr. pr Gauge. Gauge Build air pressure up to 8 bar bar. • Hold the overdrive button provided on the lever and Shift to D (drive) or R (reverse) at engine idle speed (750-800 (750 800 RPM) with service brakes ON. ON Do not shift with throttle depressed. • When selected D, the transmission will shift to 1st; depending on the accelerator position and load, up-shift and down-shift of gears will automatically take place. • Release the parking brake completely. Parking brake indicator light and beeper should be ‘OFF’. • Release the service brake and gradually press the accelerator pedal for moving the vehicle, Tips for the Driver – During running of the Engine / Vehicle During running of the engine / vehicle: • • • • • • • • • Keep watch on the indicator lights. ‘R’( Reverse) is used to back the vehicle. Completely p y stop p the vehicle and let the engine return to idle (750-800 RPM) before shifting from Forward range (D) to Reverse ® or from Reverse to a Forward range. Select ‘N’ ( Neutral)) momentarily y before making shifts from ‘D’ to ‘R’ and vice versa. Do not apply full power in ‘D’ or ‘R’ with brakes ‘ON’ Do not allow the vehicle to coast in Neutral (N). ( ) Use 1(First) range for pulling through mud, driving up or down very steep grades. Use 3 ( Third) range for city traffic and braking on steep p down-grades. g At Trafic signal, the gear shift lever to be put to “N” while the vehicle is at stopped condition and then to “D” before moving the vehicle. If the ignition switch is on but the vehicle is stand-still more than 3 minutes due to traffic or any other reason, the speed limiter comes into action and the accelerator pedal collapses and goes down. down To the raise the accelerator pedal to Normal position, position switch OFF and ON the ignition switch. Tips for the Driver – During running of the Engine / Vehicle • Apply Retarder by pressing the brake pedal. Note: Before operating Retarder, ensure that: The Retarder switch on the dash-board is pressed ON. Foot from accelerator is removed. Temperature of Transmission oil within limits ( green band range). • In case of transmission over heating, stop the vehicle, select N, apply parking brake, run engine at 1200 – 1500 rpm for 2-3 minutes to cool the converter out fluid. Note: Retarder gets automatically de-activated as soon as ABS comes into action and also as soon as accelerator l t pedal d l is i pressed. d Tips for the Driver – During running of the Engine / Vehicle • If the wheels are stuck and not turning, do not apply full power for more than 30 seconds in either ‘D’ (Drive) or ‘R’(Reverse). Full power for more than 30 seconds will cause the transmission to overheat and severely damage the transmission parts. • g stop p indicator glows g and If the engine the engine begins to stop, press the engine shut down over ride switch to run the engine in limp-home limp home mode and to bring the vehicle to the nearest authorized workshop for attending the problem. • Do not switch ‘OFF’ the ignition while driving, this makes ABS non-operational. p Tips for the Driver – During running of the Engine / Vehicle • Check gas leak indicator for any leakages. In the event of any gas leakage, immediately switch OFF ignition and isolate the electrical system using the battery cut-off switch. Close the three way valve and individual cylinder valves manually on the roof top. Get the vehicle attended to stop leakage. Tips for the Driver – While Stopping the Engine & Parking the Vehicle While Stopping the engine and Parking the vehicle: • • Bring the vehicle to a complete stop using the service brake. Make sure the engine g is at low idle rpm p (750-800 ( RPM). ) • Put the transmission in ‘N’ (Neutral) position. • Apply the parking brake and make sure it is properly engaged. • Idle the engine for at least 3 minutes before shutting down. • Cut-off electric supply by switching OFF battery cut-off switch provided on the dashboard. • Turn the three way valve to Parking position. • Close the individual cylinder valves manually on the roof top if the vehicle is to remain unused for a long time.
