Washing To help protect your vehicle’s finish from rust and deterioration, wash it thoroughly and frequently at least once a month with lukewarm or cold water. If you use your vehicle for off-road driving, you should wash it after each off-road trip. Pay special attention to the removal of any accumulation of salt, dirt, mud, and other foreign materials.If the vehicle leaves a lane, the lane marker you cross will blink on the LCD display. If the vehicle moves out its lane because steering torque for assistance is not enough, the line indicator will blink. If all the conditions to activate LKA system are not satisfied, the system will convert to LDW system (Lane Departure Warning) and only warn the driver when the driver crosses the lane lines.
