Probably check engine. If you have an owners manual check that, all the answers about that stuff is in there.
part of the car that is above the steering wheel
The dashboard light which looks like a steering wheel with an exclamation point beside it is the power steering light. If this light comes on, it either means the vehicle's power steering fluid levels are low or that there is a fault in the engine management system. When the light turns on, the fluid levels need to be checked first, and topped off if they are low. If the light remains on and the fluid is full, or should come on again when the driver returns to the road, then the vehicle should be inspected by a mechanic.
On the dash left of the steering wheel.
It is located on the dashboard by the steering wheel.
Check the power steering fluid
Failure in the power steering system...
With two buttons behind the steering wheel.
What aspect of the steering wheel/system? If you just want to raise or lower the steering wheel, there should be a handle on the left side of the steering column about halfway between the back of the steering wheel and the dashboard. Just push the handle down to unlock and adjust the steering wheel and up to re-lock it once it's in the desired position...
Looks like the center piece of the steering wheel pops out and the air bag pops.
the one between the steering wheel and the seat /\ Which is the dashboard dummie :)
There is a picture that looks similar to a steering wheel on the reservoir cover.
It should be somewhere near the steering colsole, steering wheel, or dashboard, but I don't know for sure. I don't own one.
