Keys and Locks, Immobilizer System These keys contain electronic circuits that are activated by the immobilizer system. They will not work to start the engine if the circuits are damaged. Protect the keys from direct sunlight, high temperature, and high humidity. Do not drop the keys or set heavy objects on them. Keep the keys away from liquids. If they get wet, dry them immediately with a soft cloth. On DX model (except Canadian DX-G) Immobilizer System The immobilizer system protects your vehicle from theft. If an improperly-coded key (or other device) is used, the engine's fuel system is disabled. When you turn the ignition switch to the ON (II) position, the immobilizer system indicator should come on briefly, then go off. If the indicator starts to blink, it means the system does not recognize the coding of the key. Turn the ignition switch to the LOCK (0) position, remove the key, reinsert it, and turn the ignition switch to the ON (II) position again. The system may not recognize your key's coding if another immobilizer key or other metal object (i.e. key fob) is near the ignition switch when you insert the key. If the system repeatedly does not recognize the coding of your key, contact your dealer. Do not attempt to alter this system or add other devices to it. Electrical problems could result that may make your vehicle undrivable. If you have lost your key and cannot start your engine, contact your dealer. Instruments and Controls The keys do not contain batteries. Do not try to take them apart. CONTINUED 75
