Under bonnet

[Teki Chan]

I am a new driver and am not very clear about which caps belong to which fluids. I attached the picture of under bonnet. I just know the blue cap is for windscreen fluid. Would you please advise?

In addition, for Yaris hybrid, is it true not often to refill coolants and oils? 

[FROSTYBALLS]

The reservoir with the black cap/yellow writing is brake fluid. The reservoir with the radiator symbol crossed through nearest the washer fluid reservoir is coolant (containing pink fluid).

Do check the coolant and oil levels, but doubt whether you will need to top up either by much, if at all.

Just a note. There are two coolant reservoirs.  The one on the left ( shown in the picture with pink fluid ) contain coolant used to cool the electic components ( electric engines and inverter/converter ) .  There's a second reservoir on the right side ( not shown in the picture ) for ICE coolant.  Unluckily it's not so easy to check the level of the ICE coolant ( it requires a light and some acrobatic contortions 😉 ) 

[Teki Chan]

Thank you for both replies. Do we top up brake fluid often? I saw the yellow bottle not quite full. Do I have to buy from Toyota?

Can we top up the pink coolant and ICE coolant with any coolant in any shop or necessarily from Toyota?

What about read user manual from the car before asking here? You will find some very useful information there.

Indeed. The best thing any new car owner can do is to fully read the owners manual beforehand starts to drive the car. Doing so makes you more educated and also prepared like theoretical training of pilots and then what you start driving the practical training too. Plus all you have learned from the book you can see it in real life later on. 

Straight answer to the OP - do not touch any of the caps except the blue one, this is for the windscreen wash, check and refill on weekly basis or every two weeks depending how much you use it.
All others if you are not familiar what they are for better leave them alone. Never open the pink tanks or radiator cap immediately after the car was used. And when you checking all fluids levels make sure all are at top mark or between min and max marks including oil level.
Before shutting off the bonnet point a finger directly to each cap starting left to right and make sure they are all closed. 

These cars generally speaking does not need topping up fluids or not often as some other makes does, but still requires regular checks. 👍

I'll add, DO NOT TOUCH THE SMALL BLACK CAPS. They're for the air con and specialist equipment's required.

No.  Its level will drop as the brakes wear and will come back to the top when new brakes are fitted.

If you don't have a leak (which you won't) it will never need to be topped up.

You only need to top up the blue one.  Get some screenwash from the supermarket or Halfords and use it all year round.  If it’s concentrated, dilute it 50:50 with water, if it says ready to use, just put it straight in.  It will help you clear flies and such in the summer and stop you getting into trouble with freezing pipes and blown fuses as many do in the winter. Don’t use anti freeze like my daughter did, that’s not for the screen wash.   All them other reservoirs, leave them alone.  Being a little low doesn’t matter.  Apart from anything else, you can severely scald yourself if you open when hot.  The only one you ever touch is the blue one.

If you need to top up anything between service (assuming you service to schedule, which you should!) then you have a problem and the vehicle needs repairing.

There is generally no reason to lose fluid or burn oil in any vehicle, but some are just pure trash.

Check, but generally don't touch.

The washer bottle is the only thing you need to refill regularly.

I check my car at least monthly, and oil level maybe every 3-6 months. It's 8 years old with 90k miles on it, and so far no sign of burning oil. 👍

Thank you very much to everyone for explaining that. I did read the manual but being a beginner, I feel a bit confused. I asked the question as the manual picture does not likely look the same as the actual.

I will just touch the washer fluid and leave the others to the scheduled services.

You have the wrong manual. That is for gen. 3.

Official servis plan here in slovakia is every 30 000 km or 2 years do a brake fluid service. I really doubt there will be some brake fluid drop(brake pads wear) in my case because I try to recuperate as much as possible 😄 I feel the mechanical brake are applied only from 5kmh to zero. But it's easy on wallet, 7.4€. Compare this to a eye-watering 95,40 € for a single oil change. That 3L of oil is probably harvested from very rare unicorns' blood that lives only on the moons of Saturn or something.

And in my world, If you do a brake pads change(typically on old car, or heavy use brakes), you should always do a brake fluid flush.

You don’t worry to use the brakes harder even sometimes it is good idea to slow down more progressively from high speeds to let the brakes warm up and also clean the discs from rust. Warming up the discs and pads helps clean better but also will warm up the slider pins which suffer from water and moisture locked inside that leads to corrosion and sticky brakes. Toyota hybrids barefoot use the brakes indeed and and the last ages, rust activity kills the prematurely when the car not been used regularly. 👍

Tony, of course...in a manner of safety and fun driving. 🙂 My father owns a Skoda Fabia, 2001 or something and this year do a brake job for the first time, after 180k km, and still, pretty meat left...but they were as you mention, completely rusted. Small 1.2L engine. And he is not a slow pace driver.

I don't know how some people can wear out their brakes after a year or two in normal traffic and normal cars. They must be very low mpg drivers...brake, gas, brake gas.
