What to do in an emergency ✽ NOTICE If the TPMS, Low Tire Pressure indicator does not illuminate for 3 seconds when the ignition switch is turned to the ON position or the engine is running, or if it remains illuminated after coming on for approximately 3 seconds, take your vehicle to your nearest authorized HYUNDAI dealer and have the system checked. ✽ NOTICE The compact spare tire is not equipped with a tire pressure sensor. Low tire pressure telltale When the tire pressure monitoring system warning indicator is illuminated, one or more of your tires is significantly under-inflated. Immediately reduce your speed, avoid hard cornering and anticipate increased stopping distances. You should stop and check your tires as soon as possible. Inflate the tires to the proper pressure as indicated on the vehicle's placard or tire inflation pressure label located on the driver's side center pillar outer panel. If you cannot reach a service station or if the tire cannot hold the newly added air, replace the low pressure tire with the compact spare tire. Then the TPMS malfunction indicator may turn on and the Low Tire Pressure telltale will remain on until you have the low-pressure tire repaired and replaced on the vehicle. 6 8
