UNDERSTANDING YOUR INSTRUMENT PANEL 167 and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the "Tire Pressure Monitoring Telltale Light." The "Tire Pressure Monitoring Telltale Light" will illuminate in the instrument cluster, and an audible chime will be activated when one or more tire pressures is low. The "Tire Pressure Monitoring Telltale Light" will flash on and off for 60 seconds when a system fault is detected. The flash cycle will repeat every ten minutes or until the fault condition is removed and reset. CAUTION! The TPMS has been optimized for the original equipment tires and wheels. TPMS pressures and warnings have been established for the tire size equipped on your vehicle. Undesirable system operation or sensor damage may result when using replacement equipment that is not of the same size, type, and/or style. After-market wheels can cause sensor damage. Do not use tire sealant from a can, or balance beads if your vehicle is equipped with a TPMS, as damage to the sensors may result. 6. 4LO Mode Indicator Light - If Equipped This light alerts the driver that the vehicle is in the 4 LO four-wheel drive mode. The front and rear driveshafts are mechanically locked together forcing the front and rear wheels to rotate at the same speed. 4
