Ambient Temperature Display
WARNING: This page is about a different car, the 2001 Volkswagen EuroVan, 2000 Volkswagen EuroVan, 1999 Volkswagen EuroVan, and 1997 Volkswagen EuroVan. However, it is still accessible from the selected car via links, so may be relevant.
Display will not change when vehicle speed is less than 9.5 mph (15 km/h) and coolant temperature is more than 158°F (70°C). This is done to eliminate heat radiating from the engine from interfering with CCM's calculations.
