The LDW camera sensor is on the windshield ahead of the rearview mirror.

To turn LDW on and off, press the LANE DEPART button on the steering wheel. The control indicator will light when LDW is on.

When the vehicle is started, the LDW indicator on top of the instrument panel to the right of the steering wheel will come on briefly.
LDW operates at speeds of 56 km (35 mph) or greater. If LDW is on, the LDW indicator will appear green if the system detects a left or right lane marking. This indicator will change to amber, flash, and three beeps will sound if the vehicle crosses a detected lane marking without using the turn signal. These beeps will be sounded from the left or right side, depending on the lane departure direction.
