Fluid Leak Check After the vehicle has been parked for awhile, inspect the surface under the vehicle for water, oil, fuel or other fluids. Water dripping from the air conditioning system after it has been used is normal. If you notice fuel leaks or fumes, the causes should be foundand corrected at once. Bulb Replacement Before YOU replace any bulbs, be sure that all the lights are off and the engine isn't running. Halogen Bulbs NOTICE: Avoid touching the bulb or letting it come in contact with anything damp. Oil from your skin or moisture on the bulb can cause the bulb to explode whenit is turned on. If either comes in contact with the bulb, clean it with alcohol or a suitable degreaser and wipe the bulb dry. 6-33
