I (intermittently) got this weird beeps too... 

I am sure gear were on P, all light were OFF, side mirror closed, air-cond were OFF etc...

Only not so sure if the steering lock were engage or not when I open the driver side door. Normally when we open driver side door, I can hear the built-in steering lock engaging. The only thing I suspect was maybe the steering was not rest properly for the lock to engage so the system warn us by the beep?

Other than that, I really can't think of anything that I've not done properly. 

For my case, the engine has been stopped. When open the driver door, sometimes can hear a short about 2 seconds beep sound. It's happening intermittently, and I believed the reason could be as mentioned by G K Lai that the steering not in proper position for locking.

The 3rd gen vios really has a bad FC.

bro, mine also 90% city use. 7km/l avg speed about 60-80kmh.

recorded about 600km now, 2.5 weeks car.

i m very sad.

Just report to SC regarding my "knocking" sound issue.
Need to leave car for them to record the sound.
After that, they suspected the sound came from my front lower arm.
Now need to wait the spare part to arrive.

Hi all sifu owner , please let me ask about the Eco indicator on vios j.
I just got my new vios j this month. The manual says that the Eco indicator will on if I drive on low speed , but regardless low or high , I didn't saw it light on before while driving
I only will saw it on while start engine for 3 to 4 sec only .after that it will disappear .

I am sure that ,
- Eco mode is on at the odometer long press
- drive on slow speed or normal speed , never over 90km

I just done my 1000 service today and the service guy say the light did on , only on at low speed , but after I get back the car I don't see it on .

Am I misunderstanding something or this is my car problem ?
Thanks for advance !

Really thanks for the reply andyshim89 !
In this case i think my Eco lights are broken or something.
I have double check the Eco settings is on, and my speeds are 60-90 , and pedal are stepped light.
I don't see the lights on even once. I only saw it on when i push start the engine only for 3-4 seconds.
I understand the eco indicator is just for info only but i think i need to go toyota and claim about this since this is new car so i need everything is working.

Thanks a lot for your reply !

I off the ECO mode from day 1.

I need more power as my way back home is uphill road  and many corners to tackle.

So far I m very satisfied with the acceleration speed.

i think the Eco light is just a freaking led light to trigger if you got accelerate hard or not... no genius invention here.

disabled it after i knew the way to turn if off. The blinking is annoying.

after disabled, i see no difference in performance and fc.

think again, Toyota never bang hard on this so called "ECO" mode at all. so, don't expect miracle from it.

When i collect the car from the salesman, he showed me how to toggle off and on the eco mode,
then i asked him to toggle off, he did that by disabled it by long pressing button at odo screen.

i heard if eco mode on, power reduced to 50%. 

Just done 1K service, it seems they changed to mineral oil and not semi-sync.

Hopefully FC will be better.

Bro.. just tell them.. when goin uneven road.. can hear "kada kada Kada" *I know it's funny*
and tell them when goin on humps also got the problem. Tell them during ur 20K interval

Did you do your sound proofing? If not.. just tell the Service advisor during raining time cannot even hear the radio.. cuz there's no sound proofing.. they will put in some sponge lah.. nothing that wow.. but it's a lil more bearable.

P.S after changing my lower arm also.. still got the problem... Seems my luck with toyota is bad.. =( better go for proton...lol!

oic... guess it would be 16' and above rims then.

yeap. 5 lugs mainly for bigger car with bigger rims.

normally 1.8L and above cars have 5 lugs wheel setup.

thats why Vios is 4 only.
