Set the seat and mirrors as you would for normal driving, then look forward, to the sides, and over both shoulders. Check how much the roof pillars, headrests, and rear window restrict your view. Sit in the position you would use for a long journey, because a seat set too low or too far back can make sightlines worse and reduce control comfort.
During a test drive, observe how easily you can judge the front corners and see traffic when changing lanes. Try parking in a safe, open space and assess the view from the driver’s seat before using cameras or sensors. Ask a companion to stand where you can safely identify any areas that remain hidden, without moving the vehicle near them.
Technology can help, but cameras and sensors have limits. Rain, dirt, glare, or obstacles outside a sensor’s detection area may affect their usefulness. Check the owner’s manual to understand system coverage and keep camera lenses clean. If the car’s basic sightlines feel uncomfortable even after mirror adjustment, consider another model; a helpful screen cannot replace direct observation and careful maneuvering.
