Mileage for first service?

500 miles. You're way overdue. New tundras are having trouble w mfg debris. I wouldn't risk it

Then do oil changes every 5k

 

Toyota just uses an odometer timer that goes off at 5000 miles. IIRC, the maintenance schedule of what services for each 5000 mile point is in the warranty guide. Standard oil changes are every 10k miles, so the 5000 mile point will mostly just be visual and fluid level checks, maybe rotate tires.

Was your previous car a Honda or GM?

 

Have you had a look at the Toyota USA Warranty and Maintenance Booklet? It should be in the glove box.

And yeah, all the intervals are miles or months, whichever comes first.

FWIW, I do think the miles/months thing starts to unravel, if you're super low miles. That's our scenario; I was doing oil changes every 6 months (per Toyota Canada 3rd gen recommendation), doing an oil change spring and fall. Then spring before last, did an oil change, entered it in my log, and it was barely 1000 kms since my last change. Resolved to make it once a year from then on.

Addendum:

Honda uses a Maintenance Minder, which is light years ahead: does appear to be monitoring various parameters, gives you countdown in percent to next service, and when it's down to 15% remaining, displays an alpha/numeric code that you can look up in the owner's manual, see precisely what needs doing. I don't think the dealerships like it...

Anyway, one thing it says: if the maintenance minder has not gotten down to below 15% in a year, change the oil anyway.

Another factor, and again the dealerships ignore it, the Maintenance MInder distinguishes between "oil change" and "oil and filter change", and alternates between the two.

 

our toyota dealer haunts us when it is time for service.

 

The manual says to "obtain maintenance" at 5,000 miles or 6 months, whichever comes first.

 

I've always been a Honda driver (and oil/brake/tire maintainer), so it's taking me a bit to get used to how Toyota does their service intervals. While I do like that the initial services are free, I feel that Honda's methods of determining exactly what and when to do things is better tied to how the car is used. Temps, aggressiveness, and mileage all factor into how the maintenance minder counts down. The icing on the cake would be if it could detect the actual state of the oil and quantity of suspended particulates. One can dream....

 

GM has a similar system. Maybe some others have moved to an oil monitor, but many simply don't want to pay for it. Even a basic engine hours meter for PHEVs would be a better way of handling oil change times.
