Cadillac 2009 owner manual Operation Tips

Operation Tips

•Keep the hood and front air inlets free of ice, snow, or any other obstruction, such as leaves. The heater and defroster will work far better, reducing the chance of fogging the inside of your windows.

•Keep the air path under the front seats clear

of objects. This helps air to circulate throughout your vehicle.

•Adding outside equipment to the front of your vehicle, such as hood-air deflectors, etc., may affect the performance of the heating and air conditioning system. Check with your dealer before adding equipment to the outside of your vehicle.

Warning Lights, Gages, and Indicators

Warning lights and gages can signal that something is wrong before it becomes serious enough to cause

an expensive repair or replacement. Paying attention to the warning lights and gages could prevent injury.

Warning lights come on when there may be or is a problem with one of the vehicle’s functions. Some warning lights come on briefly when the engine is started to indicate they are working.

Gages can indicate when there may be or is a problem with one of the vehicle’s functions. Often gages and warning lights work together to indicate a problem with the vehicle.

When one of the warning lights comes on and stays on while driving, or when one of the gages shows there may be a problem, check the section that explains what to do. Follow this manual’s advice. Waiting to do repairs can be costly and even dangerous.
