Transmission Fluid, Sparkplugs and more

in the us, we can go to 'toyota.com/owners' and plug in the vin to get any dealer service history.

not sure if you can do that in ca.

short of any knowledge, i would follow the maintenance interval guide for your car.

although it may not be in the ca guide (it isn't in the us) it is always good to change the ecvt fluid at any mileage. it isn't like a regular auto trans, and it can only help, not harm.

get a load test done on your 12 volt if you can, unless you know that it has been replaced. the date code is on the top, but you have to unclamp the terminal with the box on it to see it.

cabin and engine air filters should be inspected/cleaned/replaced and pump up your tyres pressure.
check the spare at the same time.

 

Full brake inspection, if there's no evidence it's been done.

Intake manifold cleaning (pay special attention to the EGR passages at each intake port). Cleaning of the full EGR system. More info:

No. I would get on it ASAP. It's a relatively easy DIY, just raise AND level the car: when refilling proper level is achieved by filling till it starts spilling back out. You'll need 4 liters of Toyota ATF WS fluid, and should get replacement washers for the drain/fill bolts (they're identical). Torque for both is 29 ft/lb's.

The bolts are socket-head cap-screw style, require 10 mm male hex driver. Get one on a "socket", so you can use on a torque wrench. A long handled ratchet wrench or breaker bar is handy for breaking loose the bolts; they tend to get a little stuck. Start with the fill bolt, just in case you have difficulty.

The fluid retails through dealership for around $9 CDN local to me, fwiw. Dealership service departments should not charge over $100, even $80 would allow them a reasonable profit.

 

Make sure you loosen the FILLER bolt FIRST!
Because if you can't get that loose AFTER the drain plug, you'll have no way of filing it
back up. Easy was, or inexpensive way that is.

 

you can always level the car upside down so the drain hole becomes the fill hole.

 

That's thinking out of the box!
