DOORS The master key can be used for all the locks. The valet key cannot be used for the console box lock. To protect belongings when you leave a key with someone, give them the valet key only. Never leave these keys in the vehicle. Additional or replacement keys: If you still have a key, the key number is not necessary when you need extra INFINITI Vehicle Immobilizer System keys. Your dealer can duplicate your existing key. As many as five INFINITI Vehicle Immobilizer System keys can be used with one vehicle. You should bring all INFINITI Vehicle Immobilizer System keys that you have to your INFINITI dealer for registration. This is because the registration process will erase the memory of all key codes previously registered into the INFINITI Vehicle Immobilizer System. After the registration process, these components will only recognize keys coded into the INFINITI Vehicle Immobilizer System during registration. Any key that is not given to your dealer at the time of registration will no longer be able to start your vehicle. Do not allow the immobilizer system key, which contains an electrical transponder, to come into contact with salt water. This could affect system function. CAUTION Always carry the mechanical key installed in the Intelligent Key slot. WARNING ● Always have the doors locked while driving. Along with the use of seat belts, this provides greater safety in the event of an accident by helping to prevent persons from being thrown from the vehicle. This also helps keep children and others from unintentionally opening the doors, and will help keep out intruders. ● Before opening any door, always look for and avoid oncoming traffic. ● Do not leave children unattended inside the vehicle. They could unknowingly activate switches or controls. Unattended children could become involved in serious accidents. Valet hand-off When you have to leave a key with a valet, give them the Intelligent Key itself and keep the mechanical key with you to protect your belongings. To prevent the glove box or console box from being opened during valet hand-off, follow the procedure below. 1. Remove the mechanical key from the Intelligent Key. 2. Lock the glove box or console box with the mechanical key. 3. Hand the Intelligent Key to the valet and keep the mechanical key with you. See "Storage" in the "Instruments and controls" section. INFINITI VEHICLE IMMOBILIZER SYSTEM KEYS You can only drive your vehicle using the master or valet keys which are registered to the INFINITI Vehicle Immobilizer System components in your vehicle. These keys have a transponder chip in the key head. Pre-driving checks and adjustments 3-3
