Hyundai Tucson: Tire pressure monitoring system  (TPMS) / Low Tire Pressure Telltale

The TPMS is not a substitute for manually checking tire pressure with a tire pressure gauge. Changes in temperature affect tire pressure. See “Tires and Wheels” in chapter 7 for proper tire inflating and tire pressure measurement procedures.

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 door jamb. 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.

The Low Tire Pressure Telltale will remain on and the TPMS Malfunction Indicator may blink for one minute and then remain illuminated if the vehicle is driven approximately 20 minutes at speed above 15.5 mph (25 km/h).

✽ NOTICE

The compact spare tire is not equipped with a tire pressure sensor.

CAUTION

In winter or cold weather, the Low Tire Pressure Telltale may be illuminated if the tire pressure was adjusted to the recommended tire inflation pressure in warm weather. It does not mean your TPMS is malfunctioning because the decreased temperature leads to a proportional lowering of tire pressure. When you drive your vehicle from a warm area to a cold area or from a cold area to a warm area, or the outside temperature is greatly higher or lower, you should check the tire inflation pressure and adjust the tires to the recommended tire inflation pressure.
