Lane Departure Warning Your vehicle may have a Lane Departure Warning (LDW) system. Read this entire section before using the system. CAUTION: (Continued) {CAUTION: The Lane Departure Warning (LDW) system does not steer the vehicle and is only an aid to help you stay in your driving lane. The LDW system may not: • Provide you with enough time to avoid a lane change collision. • Be loud enough for you to hear the warning beeps. • Work properly under bad weather conditions or if the windshield is not kept clean. • Detect lane markings and will not detect road edges. • Warn you that your vehicle is crossing a lane marking if the system does not detect the lane marking. CAUTION: (Continued) LDW will indicate the system is working whenever it detects either the left or right lane marking. So if you depart on the side of the lane that LDW is not detecting, LDW will not warn you. If you do not carefully maintain your vehicle position within the lane, vehicle damage, injury, or death could occur. Even with LDW, always keep your attention on the road and maintain proper vehicle position within the lane. Always keep the windshield clean and do not use LDW in bad weather conditions. When you cross a detected lane marking, the LDW symbol will flash and you will hear three beeps. LDW will not warn you if your turn signal is on or if you make a sharp maneuver. Before making a lane change, check your vehicle's mirrors, glance over your shoulder for vehicles and hazards, and start your turn signal before changing lanes. 2-44
