In the fuse box on your driver side, at the top is a red button that says reset. Just hit that and your good to go...

Stock Wheels?

i have a similar problem. I recently bought the car and noticed that it needs air. checked air pressure on the tire on a couple of them i got 45 psi, 35 on another and 22 on the front driver's. the light came on after i have made adjustment to the tire pressure to reflect approx. 30 psi recommendation posted on the door. My 15" Tire however states 35 psi is recommended. What is the correct tire pressure and is there anything else we can look into to remove the low tire pressure light on the dash?
thanks,

The tire pressure is what ever it says on the door

Thanks. I Also found out from one of the posts that the ignition has to be on the "ON" position to be able to toggle through the options that can be reset - one of them would be the Low Tire Pressure indicator.

sometimes I have to hold the button for 30 seconds or so before it will reset. The owners manual has the procedure for resetting both the tire light and the change oil light.

This is not true.
Your tire pressure is what it states on the tire.
The door sticker is for your stock OEM tires.

Thanks, this actually makes sense since the tire pressure on the door is meant for the stock wheel/tire combo that the car was engineered for.
I know proper inflation does affect mileage on the car. I wonder if somene out there has experimented with this?? Who gets better mileage - the ones who follows the "door" or the tire manufacturers?

Higher tire pressures will result in better mileage, due to the lower rolling resistance. However, they will also result in increased vulnerability to damage from potholes, and other road hazards. Depending on the amount of pressure, you could also lose some grip.

Your car doesn't actually measure tire pressure. It measures the rpm of the wheels. If you have a low tire the rpm from the wheel speed sensor will be different than the other tires and you will get a light on the dash. True tire pressure monitors (TPMS's) became mandatory on 2008 vehicles. They are in the wheel and part of the stem and transmit pressure to the receiver module in the car via an RF signal.

Set the tire pressure with the car cold, reset the dash light per instructions in your manual. Over inflation will give you a hard ride, will wear in the center and is more susceptible to road damage. Under inflation will cause wear on the outer edges and a mushy noisy ride. In both cases handling will be affected as will traction.

i guess this implies that we should be following the tire manufacturer's inflation guideline since generally, they specify a higher psi value for tire inflation compared to car manufacturers.
