CAUTION
Do not leave the ignition key inside the vehicle when you leave the vehicle.
A key number plate is supplied with your keys.
Record the key number and keep it in a safe place (such as your wallet), not in the vehicle. If you lose your keys, see a NISSAN dealer for duplicates by using the key number. NISSAN does not record key numbers so it is very important to keep track of your key number plate.
