Switching off air con and radio

[Karfield]

Is it necessary to switch off air con and radio?

[Tkl07]

if you are so concern about FC, maybe u also want to take out spare tyre, rear seat...

[Dwoon]

Yes. Absolutely. Since there are buttons provided to do so.

[Blackyv]

i think he ask it when off engine...

yes, i switch off aircon but not radio.. maybe due to old habits becuas eiwth air-con on, it's harder to crank an old car...

[Tkl07]

he didnt specify mah,,,

Actually, with modern technological advances, is it still better to start your engines with your radio, aircon, etc (and warning indicators sound) off?

 

Does it still matter? I am still starting the engine with the buttons off...

[Wilb]

I don't. No problem with it yet.

[Touch_n_go]

starting engine with radio/air con off does help u to save some electricity, oso the battery can provide more power to the starter motor..

[Tkl07]

I think off will be better, as sudden surge in power supply to the aircon n radio may affect it

actually, if u ask me, with todays technology, should not have problem but as usual, kiasi mah...

[Chemz]

aircon maybe, radio most probably not necessary

i would turn off both a/c and radio before starting engine.

 

a/c off to save battery power

 

radio off to protect the circuitry in the HU and amps

Well, do u think it's feel good if u were force to run 2.4km once u wake up from your sleep early in the morning?

[Fastwannabe]

i think offin e air-con will do, i have a fren with an EP70, must off air-con to start car, if not very unhealthy for e engine???..C&C also say to "increase" e life of your engine, it is better to off e air-con when u wanna start your car, so just off it lor...it wun hurt but it may do some good

Reason I ask cos previously used to drive a Honda and was told by the mechanic that it is not necessary to off air-con. But now I have changed to a Latio and the SE told me that it is a good habit to off the air-con before I switch off the engine. That is why I am confused.

 

Also I realised that when I switch on the air con after starting the engine, the air-con start off with a loud sound followed by a hissing sound. I don't have this problem with my Honda. When I send my car for the 1st thousand servicing, I told the mechanic about the sound and was told it is normal. I forgot to check with him whether I need to switch off the air-con

Starting the car with aircon on makes ur engine push out more "strength" and it'll hurt ur engine alittle.

 

Same theory applies that will u feel xiong when u just wake up and ask u to run 2.4k?

 

 

Nowadays, its ok to just keep ur aircon on, but it'll still be a good habit to have it in the off position when u warm up. Good for the engine and make it lasting. My friend's evo can't start up with aircon switched on. It'll just keep storing.

Not necessary. The ECU will only turn on the aircon compressor after engine is on for a couple of seconds.
