STARTING AND DRIVING CAUTION To avoid accidents, always keep the laser radar sensor glass clean and never allow it to be covered with icicle or any substance, so it can detect the vehicle in front. (See "(k) Laser radar sensor" on page 478.) CAUTION Do not rely excessively on dynamic laser cruise control. Observe the following precautions in order to avoid serious injury or death: D Under certain conditions where the vehicle in front slows drastically, or is stopped, the dynamic laser cruise control will neither warn you nor decelerate. You must depress the brake pedal to slow down, ensuring collision avoidance or that sufficient vehicle-to-vehicle distance is maintained. D Do not use dynamic laser cruise control in the following conditions: In bad weather (such as rain, fog, snow, sandstorms or direct sunlight, or when raindrops or snowflakes get on the laser radar sensor glass), the vehicle-to-vehicle distance will not be measured accurately. When using the windshield wipers at high or low speeds the dynamic laser cruise control turns off. On roads with heavy traffic or sharp bends, an appropriate speed cannot be maintained and an accident may occur. 469
