Audio Antenna, Intercooler, Dust and Pollen Filter Audio Antenna ANTENNA Intercooler Do not spray water (from such sources as garden hoses, high pressure sprayers) into the engine compartment. It may cause serious damage to your vehicle, and could also damage the intercooler fins. Dust and Pollen Filter This filter removes the dust and pollen that is brought in from the outside through the climate control system. Have your dealer replace the filter when this service is indicated by a maintenance message on the multiinformation display. It should be replaced every 15,000 miles (24,000 km) if you drive primarily in urban areas that have high concentrations of soot in the air, or if the flow from the climate control system becomes less than usual. INTERCOOLER Maintenance Your vehicle is equipped with an antenna at the rear of the roof. Before using a ''drive-through'' car wash, remove the antenna by unscrewing it by hand. This prevents the antenna from being damaged by the car wash brushes. Your vehicle is equipped with a intercooler on the engine to cool the air flow from a turbo charger into the engine. The intercooler fins bend easily. Do not push them with your finger. 439
