Keys and Locks, Immobilizer System You should have received a key number tag with your keys. You will need this key number if you ever have to get a lost key replaced. Use only Acura-approved key blanks. Immobilizer System The immobilizer system protects your vehicle from theft. If an improperly coded key or keyless access remote (or other device) is used, the engine's fuel system is disabled. When you turn the ignition switch to the ON (II) position, or select the ON mode with the engine start/ stop button, 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 or keyless access remote. On models without keyless access system, 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. On models with keyless access system, set the power mode to VEHICLE OFF (LOCK), then select the ON mode again. The system may not recognize your key's or remote's coding if another immobilizer key or other metal object (i.e. key chain) is near the ignition switch or the keyless access remote when you insert the key or set the power mode to ON. : On models with keyless access system Your vehicle has the engine stop/start button instead of an ingition switch. See page 187 for a comparison between conventional power switches and your engine start/stop button For more information on selecting the power mode, see page 184 .
