2007 Lexus LX 470 Navigation Manual - Page 235

CAUTION D For safety, the driver should not operate the navigation system while he/she is driving. Inattention to the road and traffic may cause an accident. D While you are driving, be sure to obey the traffic regulations and maintain awareness of the road conditions. If a traffic sign on the road has been changed, route guidance may provide wrong information such as the direction of a one way street. While you are driving, listen to the voice instructions as much as possible and glance at the screen briefly and only when it is safe. However, do not totally rely on voice guidance. Use it just for your information. If the system cannot determine your current position correctly, there is a possibility of incorrect, late or non-voice guidance. The data in the system may occasionally be incomplete. Road conditions, including driving restrictions (no left turns, street closures, etc.) frequently change. Therefore, before you follow any instruction from the system, look to see whether you can comply with the instruction safely and legally. This system cannot warn you about such things as the safety of an area, condition of streets, and availability of emergency services. If you are unsure about the safety of an area, do not drive into it. Under no circumstances is this system a substitute for the driver's personal judgement. Use this system only in locations where it is legal to do so. Some states/provinces may have laws prohibiting video screens within sight of the driver. v
