120 UNDERSTANDING THE FEATURES OF YOUR VEHICLE When the High setting is selected, the heater will provide a boosted heat level during the first four minutes of operation. Then, the heat output will drop to the normal High-temperature level. If the High setting is selected, the system will automatically switch to Low after 30 minutes of continuous operation. At that time, the number of illuminated LEDs changes from two to one, indicating the change. The Low setting will turn Off automatically after 30 minutes. NOTE: Once a heat setting is selected, heat will be felt within two to five minutes. WARNING! • Persons who are unable to feel pain to the skin because of advanced age, chronic illness, diabetes, spinal cord injury, medication, alcohol use, exhaustion or other physical condition must exercise care when using the seat heater. It may cause burns even at Low temperatures, especially if used for long periods of time. • Do not place anything on the seat that insulates against heat, such as a blanket or cushion. This may cause the seat heater to overheat. To avoid heated seat surfaces coming in contact and potential seat overheating, always ensure that the seat heater is in the Off position (amber lights indicate High/Low/Off) before placing any of the seats into a folded flat position (if equipped).
