Your cars battery must be fairly healthy for this to work. If it is totally dead your sparkplugs wont fire, and the car will not start.

Word of warning: Brakes & Power Steering don't work until the engine is running.

1. Car in neutral, Emergency Brake off.
2. Push car up to ~ 5-10 MPH.
3. Turn key in ignition to "RUN".
4. Depress clutch pedal.
5. Engage 3rd gear.
6. Release clutch pedal.

Car should start.

do this only if you are stranded in the desert and it is 140 out and the nearist living person is 300 miles away. never push start an AWD car unless your life depends on it!!!

my 2 cents

Yeah, why 3rd? 5th is easier on both you and the tranny.
Don't let these guys scare you. If your battery is kaput and you need to get it started, go ahead and do it. Is it a good idea to do it every time you start your car? Probably not. Will it hurt your car if you do it once when you're stranded? No more than getting a jump start might. Damage center diff versus fry entire electrical system? It's a toss up. The benefits also outweigh the risks, if you ask me.
You can do it in reverse, but it's a lot harder on the car.

Excuse me, but why would it be bad for an AWD car, or for the center diff, to push start a car? (Manual version, of course) I just can't think of a reason why.

Both ends of the car are moving - this shouldn't be a problem. I've actually jumped started mine in reverse by accident...

if you ever push started a 2wd drive car, you would seet that by doing this it usally ends up in locking the rear diff, ie one wheel locks and hops....push starting any car is bad.

Imgine locking both front and rear differentials at the same time. 4 wheels spining, then bam one locks bam another locks, it twists the drive train in oposite directions, putting undue stress on the center diff. Hard to explain...trust me its bad.

It even says it in your owners manual. You know that little book in the glove box still wrapped in plastic hehe

Since when is jump starting a car risking frying you electrical system, unless your dumbass and you hook up the cables wrong there is NOWAY your going to fry your electrical system if you jump start your car. Dont take anything Ive said to heart not trying to start a flame war.

My suggestion do not push start your car,
Subaru suggestion: do not push start you car.
Good enough for me

Maybe it was a fluke with '00 Imprezas. Please post the page/scan. I just spent the last 30 minutes or more re-reading my entire owner's manual and there is nothing in there about push starting.
There are places where the police won't jump-start your car because there is a risk of damaging your (or their) electrical equipment during the jump. Is it a large risk? No. No more than the risk to your differentials during a push start. If you use 5th gear the chances of compression lock are quite slim, unless you aren't moving.
Any time you use electricity there is a chance of surge. When jump-starting a vehicle it's still there. Plus there is the risk of somebody not hooking the wires up right, or the battery exploding...

I have had to push start, or roll start, my 2wd cars a lot over the years, both FWD and RWD and never had the diffs "lock". Actually I don't like the word lock at all when talking about what is going on...The diffs don't lock, the driveshaft coming to it stops, but the inertia of the things beyond the diff still spinning can cause problems.

Anyway, I've never had it happen. The reason I guess is how I do it. I let out the clutch just enough to grab the engine and spin it, but if the motor refuses to start (or if it does start) I immediatly step back on the clutch. I never let it fully engage. Have to admit never had to try it on my scoob.

I always used 2nd gear in my Toyota. I would suggest you never use 1st though, way too much stress on car.

5th gear is way easier to use than 1st. Try it sometime. It's nowhere near as violent when the clutch engages. Your engine doesn't need to turn over very much before it starts, and 5th gives you better leverage.
In fifth the motor turns over about 3 times per rotation of the tire. In first it's closer to 13. (these are rough guesses) Maybe I have only done it with a charged battery, but it's always easier on the car in 5th.

Why do you think they tell you to put the car in 1st or reverse when you park? It's because it takes a lot more energy to move the car. (Owner's manual, look up parking in freezing temps - don't use e-brake)

Obviously, it is easier in a lower gear, I'm just sayin that you need some good momentum to get her goin i.e. 25 mph push.

It's easier in a *higher* gear.

Think about it: it's easier for the engine to push the car in first. It's easier for the car to push the engine in fifth.

But the engine might not be moving fast enough to turn over if you use fifth.

Any car with a cat will probably say not to push start it. Makes sense, the emissions system isn't running right at that time and you might turn the engine over once or twice with no spark = gas in cat.

Personally I'll sometimes roll-start the car if I stall out doing something on a hill. Yeah it's bad for it, but probably not too much. What's the starter motor do anyway?

Yeah.. this got me thinking the other day... What's the difference between engine braking and push starting? Hmmmmmmm.

Push starting there isn't spark right away.

I don't know about you, but my car dumps gas down the exhaust all the time. I can hear it popping when I lift the throttle.

And the owners manual suggests that you use engine braking on hills.

Also, the auto tranny downshifts on down grades if you lightly tap the brake.

So saying that push starting the car is bad is poo poo.
