Ventilation Tips
Keep the hood and front air inlet free of ice, snow or
any other obstruction such as leaves. The heater and
defroster will work better, reducing the chance of
fogging your windows.
Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.
When the engine idles for a long time, the exterior
temperature sensor may cause the system to blow air
that is too cool. Once the vehicle is moving again,
the system will try to maintain the set temperature
inside your vehicle.
When you start your vehicle and the EXT display
flashes (Dual Automatic Comfortemp system only)
for some time, the system may need repair. See
your dealer.
