Download TIRE PRESSURE MONITOR WARNING LIGHT When the tire pressure warning light comes on, immediately check the air pressure of all tires. If the tire pressure was normal in all tires, the system needs to be initialized. See INITIALIZING TIRE PRESSURE MONITOR SYSTEM. If a tire is flat, repair as necessary. If a tire inflation is low, adjust to the specified pressure. Push tire pressure warning system reset switch for a few seconds, and make sure the warning light goes off. If the warning light stays on or blinks once every second, there is a malfunction in the TPM system. See appropriate manufacturer service information. If the warning light blinks twice every second, the system needs to be initialized. See INITIALIZING TIRE PRESSURE MONITOR SYSTEM. Under the following conditions, the system may not function properly: – A compact spare tire, snow tires, or tire chains are used. – The tire pressure is excessively higher than specified, or tire pressure suddenly drops due to bursting or other causes. – The vehicle is driven on a slippery road surface such as rough or frozen roads. – The vehicle speed is 19 MPH (30 KM/H) or less or more than 62 MPH (100 KM/H), and the driving duration is less than 5 minutes.
