1. Check your tire pressure: Use a reliable tire pressure gauge to check the pressure in each tire, including the spare. Compare this to the recommended pressure listed on a sticker usually found on the driver's side doorjamb or in your owner's manual.
2. Inflate tires: If any tire is underinflated, inflate it to the correct pressure. Use a compressor or air pump at a gas station.
3. Check for leaks: After inflating, monitor the tires for a few days to see if any lose pressure. A slow leak might require repair or replacement. Look for punctures, embedded objects, or damage to the tire sidewalls.
4. Reset the system (if necessary): After inflating tires to the correct pressure and driving for a short distance (often 10-20 miles), the light *should* turn off automatically. If it doesn't, your Impala likely has a Tire Pressure Monitoring System (TPMS) that needs to be reset. The method for resetting varies slightly depending on the specific trim level of your 2005 Impala. Consult your owner's manual for the precise instructions. Some methods involve:
* Driving for an extended period: In some cases, simply driving for a longer distance (sometimes up to 100 miles) might reset it.
* Using a scan tool: A TPMS reset tool or a more advanced OBD-II scanner can be used to reset the system. Auto parts stores often have these tools available, or you might have one for other vehicle maintenance.
5. If the light remains on after inflation and resetting: There may be a problem with the TPMS sensors themselves, a faulty sensor, or a more serious issue requiring professional attention. Take your Impala to a tire shop or mechanic for diagnosis.
Important Note: Driving on underinflated tires can lead to:
* Reduced fuel economy: Underinflated tires increase rolling resistance.
* Uneven tire wear: This leads to premature tire wear and potentially dangerous handling.
* Increased risk of a blowout: This can result in loss of control and accidents.
Don't simply try to turn off the light; fix the cause of the low tire pressure first!
