UNDERSTANDING THE FEATURES OF YOUR VEHICLE 119 After turning the ignition ON, you can choose from a High or Low heat setting. Illuminated LEDs on each switch indicate the level of heat in use. Press the switch once to select High-level heating. Press the switch a second time to select Low-level heating. Press the switch a third time to shut the heating elements Off. Two indicators will illuminate for High, one for Low, and none for Off. When the High-level 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-level. If the High-level setting is selected, the system will automatically switch to Low-level after approximately 30 minutes of continuous operation. At that time, the number of illuminated LEDs changes from two to one, indicating the change. The Low-level setting will turn Off automatically after approximately 30 minutes. NOTE: Once a heat setting is selected, heat will be felt within two to five minutes. 3 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. (Continued)
