OPERATING YOUR VEHICLE WARNING (Continued) Accordingly, when the low tire pressure telltale illuminates, you should stop 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 TPMS low tire pressure telltale. WARNING The tire pressure monitoring system is not a substitute for regular tire pressure inspections. Check tire inflation pressures monthly when cold and set to the recommended inflation pressure as specified on the vehicle's tire information placard and in the owner's manual. Refer to "Tires" in the "INSPECTION AND MAINTENANCE" section. WARNING The load rating of your tires is reduced at lower inflation pressures. If your tires become even moderately under-inflated, the vehicle load may exceed the load rating of the tires, which can lead to tire failure. The low tire pressure warning light will not alert you of this condition. The warning light will only come on when one or more of your tires become significantly under-inflated. Check and adjust your tire inflation pressure at least once a month. Refer to "Tires" in the "INSPECTION AND MAINTENANCE" section. WARNING If the low tire pressure warning light does not come on when the ignition is turned to the "ON" position, or comes on and blinks while driving there may be a problem with the tire pressure monitoring system. Have your vehicle inspected by an authorized SUZUKI dealer. Even if the light turns off after blinking, indicating that the monitoring system has recovered, make sure to have an authorized SUZUKI dealer check the system. 6-22
