Hi , great thread this helps a lot of new car owners, I have a question there is no glow plug light which comes up on a Tata safari 3.0 even though there is an icon for that in the instrument cluster which never lights up when I checked with TASS they said that 3.0 does not have a glow indication s/w installed as the heating is done as soon as we put the key in , is this true .
this can be true or they may be bluffing it. Even in ritz diesel in my case i do not see the light coming on, very few times i see it but that too for about 1/10th of a sec or so.
The manual says the light might glow for a long time in extreme cold conditions, which never happens in india,,may be in srinagar.Northern india belt ritz diesel owners may have something else to tell, lets wait for them to answer.
When the engine is running, it keeps charging the battery via the alternator. When the engine is off, battery charging does not take place. This is why you should avoid using any electrical component that eats up a lot of battery (AC, music system, headlamps) while the engine is switched off.
Initial idling is required on a cold engine for the oil to circulate inside the engine and lubricate all it's moving parts. This is a good practice and ensures a longer life of the engine. Typically, idling any engine for 30-60 seconds is good enough.
