You should turn it off when you crank the car.... I make sure that ALL electronics are off before starting the car, Its easier on the engine during start up..You might as well turn it all off before shutting off the engine as well...Tiny

It is not bad for the engine, per se, but it may put a slight extra load on the starter at start-up ONLY IF the charging system has been lax in maintaining the battery. If your alternator and battery are in good working order and you have not added so many extra electronics as to exceed the alternator's normal output (normal amperage use exceeding charging capacit) you are fine. I have had IASCA competition systems in all of my cars for the past 11 years and never had a problem SO LONG AS you remain cognizant of amperage need and ability of the charging system to meet the need. Otherwise, every owner's manual in the world would tell you to shut everything down before turning the car off and on.
SIDE NOTE:Currently, my GS 400 is under construction for the Pro Class and plan to debut it at the NJ State Championship IASCA event on Aug 12. 600 watt system, 90 amp PEAK draw, 35-40 average, 10-12 nominal amp draw, no new alternator or battery

Cutoff..
As far as I remember, I've read somewhere that the AC clutch disingages when the car is off, and doesn't hook up again until a few seconds after an engine start. So, leaving the AC on shouldn't affect cranking the V8.

Ray,
the problem is not when you turn-off the car. as others have said, when you first crank-up the car in the morning, that is when future problem and stress that would be bad. for me, even after i start the car in the morning, i try not to turn-on the a/c until the engine warms up a bit.
i though irvine is not as hot as up here?:eek:

OIC.
I live in Cerritos which is between Irvine and Diamond Bar. Recently it's up to 97 degrees during lunchtime. Anything over 80 is hot for me. j.k

The V8 in the GS4 is a TANK.

i am just giving Ray(didn't you see the addressee?) my personal driving habits and perspective as i try not to stress the engine when it is cold, and that is how i pemper my car.
some people say you do not need to wax today's car because of the better paint quality. yet some of our members including myself spend several hours detailing our cars. are you going to ask them "what makes you think it is bad for NOT waxing the car?"
the key word here is stress. and i try not to impose that on both the car, and my babe, no matter how tolerant they are. anything wrong with taking it easy with the TANK.
i have never/tried to object others feedback since day one, is there any need for the sarcasm?

Do you own a car cover too?
Do you shift to neutral and coast down hills to avoid stressing the engine?
Do you worry over whether it's less stressful to downshift or apply the brakes?
OK, now I'm being sarcastic.

the answers to all your questions are yah...and...
i don't stress the car when it is cold, or when i choose not to. that disqualifies me from automobile ownership? i did not know such is stated in the constitution. you choose to stress your ride that way you like it, did i question you? i am certain many members on board also try not to stress their cars and have car covers, are you going to send them the same message.
i can't direct my comment to RAY? why don't you go ahead and remove it? tons of fellow members address their private message in the open forum, i am sure you see something you detest. why don't you go ahead and remove them all. or go around your hood and tell whoever is waxing his/her valuable possessions that they are wasting time.
i can't beleive a comment to my bud RAY desreves this much attention.
can i have fellow members' attention please:
to all who seek my limited and humble knowledge when it comes to cars, please only use PM. i am forever banned from addressing your question on the open "public" forum, not by Michael, but another member.

I personally don't think it's a bad thing in a car like our Lexus. In most other cars, the components stay on while you are starting them. But since the GS is all automatic with the operation, it seems to ramp up the use. If you notice when you start your car for the first time, and you left the A/C on, it first starts out with no fan at all, and then ramps it up as necessary. It works the same for winter, where it starts out at nothing, and after the car warms up, then gives you heat.
It's almost a personal preference. In other cars that don't do that, I've always turned off the A/C. But in the Lex, I leave it on all the time.

Sorry you're so sensitive man.
No - did I say it did? I'm just to let you know that you don't need to be so worried about stressing the car, that's all.
Now who's being sarcastic?
As far as directing comments - that's fine, like I'm directing my comments to you, but if someone wants to comment on my comments to you, that's fine, it's a public forum. And no, I can't remove any messages.
That really isn't necessary. No one has banned you. You can direct comments to anyone, but you can't expect that no one BUT the person you direct comments to will respond. Chill out.
