Keys, Doors, and Windows 2-13 Immobilizer Operation (Passlock U.S. Only) Passlock® is a passive theft-deterrent system that enables fuel if the vehicle is started with a valid key. If an incorrect key is used or the ignition lock cylinder is tampered with, the fuel system is disabled and the vehicle does not start. The security light turns off approximately five seconds after the engine is started. See Security Light on page 5‑19. If the engine stalls and the security light flashes, wait about 10 minutes until the light stops flashing before trying to restart the engine. Release the key from START as soon as the engine starts. If the engine does not start after three tries, the vehicle needs service. If the engine is running and the security light comes on, the engine restarts if you turn the engine off. However, the Passlock® system is not working properly and must be serviced by your dealer. The vehicle is not protected by Passlock® at this time. See your dealer for service. In an emergency, call the Roadside Assistance Center. See Roadside Assistance Program (U.S. and Canada) on page 13‑8 or Roadside Assistance Program (Mexico) on page 13‑10. Do not leave the key or device that disarms or deactivates the theft deterrent system in the vehicle. Exterior Mirrors Convex Mirrors { WARNING A convex mirror can make things, like other vehicles, look farther away than they really are. If you cut too sharply into the right lane, you could hit a vehicle on the right. Check the inside mirror or glance over your shoulder before changing lanes. The passenger side mirror is convex shaped. A convex mirror's surface is curved so more can be seen from the driver seat.
