INTRODUCTION — Precautions for Vehicles Equipped with a Catalytic Converter, Precautions for Vehicles with an Audio System with Built-in Anti-Theft System IN-11 PRECAUTIONS FOR VEHICLES EQUIPPED WITH A CATALYTIC CONVERTER CAUTION: If large amounts of unburned gasoline flow into the converter, it may overheat and create a fire hazard. To prevent this, observe the following precautions and explain them to your customer. 1. Use only unleaded gasoline. 2. Avoid prolonged idling. Avoid running the engine at idle speed for more than 20 minutes. 3. Avoid spark jump test. (a) Spark jump test only when absolutely necessary. Per- form this test as rapidly as possible. (b) While testing, never race the engine. 4. Avoid prolonged engine compression measurement. Engine compression tests must be made as rapidly as possible. 5. Do not run engine when fuel tank is nearly empty. This may cause the engine to misfire and create an extra load on the converter. 6. Avoid coasting with ignition turned off and prolonged braking. 7. Do not dispose of used catalyst(s) along with parts con- taminated with gasoline or oil. PRECAUTIONS FOR VEHICLES WITH AN AUDIO SYSTEM WITH BUILT-IN ANTI-THEFT SYSTEM [DIAGRAM: Cassette Tape Slot Cover with label "ANTI-THEFT SYSTEM" and reference number IN-2526] Audio Systems displaying the sign "ANTI-THEFT SYSTEM" shown on the left has a built-in anti-theft system which makes the audio system soundless if stolen. If the power source for the audio system is cut even once, the anti-theft system operates so that even if the power source is reconnected, the audio system will not produce any sound un- less the ID number selected by the customer is input again. Accordingly, when performing repairs on vehicles equipped with an audio system having a built-in anti-theft system or removing the audio system the customer should be asked for the ID number so that the technician can input the ID number afterwards, or else a request made to the customer to input the ID number. For the method to input the ID number or cancel the anti-theft system, refer to the Owner's Manual.
