Subaru Forester: Warning and indicator / Icy road surface warning light (if equipped)

When the outside temperature is 378F (38C) or less, the icy road surface warning will illuminate to inform the driver that the road surface may be frozen.

NOTE

• The outside temperature indicator shows the temperature in the area around the sensor. However, the temperature may not be indicated correctly or the update may be delayed in the following conditions.
  • While parking or driving at low speeds
  • When the outside temperature changes suddenly (example: when going in and out of an underground parking area or when passing through a tunnel)
  • When starting the engine after being parked for a certain period of time
• The icy road surface warning screen should be treated only as a guide. Be sure to check the condition of the road surface before driving.
• Once the icy road surface warning screen appears, it will not disappear unless the outside temperature has increased to 418F (58C) or higher.
