What exactly to do during BreakIn Period

i got 116 on the odo, 81 by me. I looked at the manual for the break in directions and im confused at them.

Im not supposed to stay in low gears for long time but also not suppose to drive at high speed prolonged.

I have manual, and i dont have a tach yet, so i cant see how i should shift. Iv been doing half freeway half city, best i can do to balance it high and low gears.

Whats the shift points for break in period?

Best thing you can do for engine break-in is normal city driving. That gives you a good mix of different engine speeds.

Shifting every 20 mph is a good mid-range (about 4,000 rpm) shift. Shifting at 25 mph increments will stretch it a little more, but still far from hurting anything. 30 mph is getting near the limit. The car will do a little over 60 mph before hitting the rev limiter in 2nd gear, for example.

Don't worry about it too much, though. Just drive it. Most important thing is just to avoid holding a constant speed for a long period of time. You wouldn't want to do something like go on a road trip through the desert with a brand new car and set the cruise control at 80.

When i got my car w/ 7 miles and commuted to De Anza Community College, 23 mile one way from my place...this was my shift pattern~

1st - 0-9pmh
2nd - 10-19mph
3rd - 20-32mph
4th - 33-44mph
5th - 45-65mph

Don't go above 65mph, i usually didnt, except to get out of the 18-wheelers path and passing traffic/slow drivers.

lol..iv been going too easy on the car then. Surprised to feel the car handle low speeds on the higher gears so well. One of the things i noticed coming from my 98 manual taco, like the sloppy in gate feel, and stalling 3 times on the test drive...im still getting use to the clutch, spoiled by my add on tach on that taco.

Ill be sure not to go as easy as i have been doing these 2 days.

The Yaris clutch takes a little getting used to. It's NOT you.

What Kioshi did, basically shifts at 10 mph, is a pretty good "economical" way to drive. But, it doesn't rev the engine over 2500 rpm. You do need to let the engine rev SOME to break in properly.

When I'm driving for economy and not trying to stay out of the way of traffic, I usually drop into 5th at about 35-40 and just idle up to cruising speed. Yes, the Yaris handles low RPM in higher gears just fine. (just don't expect it to accelerate from there)

so to be clear, the economical way to shift is also the "break in" way? And just dont do so much freeway.

Not quite.

You don't want to rev too high (for an extended period... a quick blast to the rev limiter won't hurt anything) during break-in, that's true. But, you can't baby it consistently or it might not break in properly.

For ultimate economy, you're going to baby the engine and shift as early as you possibly can, which is absolutely not good for break-in.

For break-in, you want to be in between those two extremes. Like I said before, if most of your driving is in the city, just drive it normally and let it rev out a bit a few times each day to be sure you're properly "exercising" the engine during the first couple tanks of fuel. After that, do what you want.

I recently bought an automatic 2009 Yaris HB and the dealer briefly mentioned to me in casual conversation that I shouldn't drive at the same speed for extended periods of time for the first 1000km.

But then I see this thread and it seems there is more to it than just that, but the tips seem to be geared (no pun intended) more towards manual transmission rather than automatic.

Should I be careful of how I'm driving the car? Or will the automatic transmission deal with it? I've basically been driving primarily in stop-and-go traffic, usually at 40km/h, or 60-80km/h. Went on the highway twice, ranging from 90-120km/h. Sometimes I'll go a little heavy on the accelerator out of a traffic light, sometimes I'll go easy on it.

Am I okay with how I'm driving? This is basically my normal driving self, except I'm being more cautious to not drive at a constant speed for a long time.

For an auto, just drive it normally but not too gingerly. The occassional spirited event won't hurt things, it may actually help; and don't be afraid to shift the transmission a bit.

Thanks! That's pretty much how I've been driving for the most part. Good to know.

When I test drove a stick with 10 miles on the car, I drove it like I stole it. Three days later when I bought an automatic I drove it like my grandmother would. I suppose that in a 10 mile test drive I didn't do too much damage to the stick.

Same here, when I test drove the yaris I also drove it like I stole it, tore around town for about 30 minutes. Then took it back and said I'll take it!

I pretty much followed the instructions in the manual exactly. No long periods at one speed, varied driving, nothing too crazy. But after seeing the 300k (well 320 something now) yaris, and hearing how he treated his the first 500, I kind of wish I did a harsher break in. Either way, I'm at 70k with no problems - I think toyota is too smart(and knows americans are too dumb) to make an engine that will break if it isn't treated in a certain way for the first 500-1000 miles

Last year I broke my LB in on the highway driving from St Louis to Tampa, FL. 7k miles later, it drives fine. Don't be afraid to put it on the highway if necessary.
