STARTING AND DRIVING (k) Laser radar sensor CAUTION To ensure that dynamic laser cruise control will function properly while driving, observe the following: D Always keep the laser radar sensor glass clean. When cleaning, use a soft cloth and be careful not to damage the sensor. D Avoid strong impacts around the laser radar sensor. An incorrect laser radar sensor alignment will result in system malfunction. A special device is required to adjust the laser radar sensor alignment.

Before using the vehicle-to-vehicle distance control mode, make sure the laser radar sensor glass is clean. This product is a class I laser product complied with 21 C.F.R part 1040.10. and 1040. 11.
