StabiliTrak® Indicator Light For vehicles with the StabiliTrak® system, this light comes on briefly while starting the engine. Lane Departure Warning (LDW) Light For vehicles with the lane departure warning system, this light briefly comes on green while starting the vehicle. If it does not, have the vehicle serviced by your dealer. If the system is working normally the indicator light then goes off. If the light comes on and stays on while driving, there could be a problem with the StabiliTrak ® system and the vehicle might need service. When this warning light is on, the StabiliTrak® system is off and does not limit wheel spin. The light flashes if the system is active and is working to assist the driver with directional control of the vehicle in difficult driving conditions. See StabiliTrak® System on page 5 ‑ 5 for more information. If it does not, have the vehicle serviced by your dealer. If the system is working normally the indicator light then goes off. This light also comes on green if the system detects a left or right lane marking. It flashes, changes to amber, and three beeps sound, if a detected lane marking is crossed without using a turn signal. See Lane Departure Warning (LDW) on page 3 ‑ 43 for more information. 4-50
