Where is the radar switch on the Lexus RX?
2 Answers
Lexus RX's radar switch is located next to the gear shift lever and is used to turn the vehicle's parking radar system on and off. Engaging reverse gear activates the parking radar, while in forward motion, the front radar is typically turned off by default in most models. Shifting into reverse gear automatically turns on the parking radar. The Lexus RX has body dimensions of 4890mm in length, 1895mm in width, and 1705mm in height, with a wheelbase of 2790mm. The front suspension is a MacPherson independent suspension, and the rear suspension is a double-wishbone independent suspension. It is equipped with a 3.5L naturally aspirated engine paired with an electronic continuously variable transmission.
I remember driving this car before. The radar switch is usually located in the button area on the left side of the steering wheel, marked with a small icon resembling radar waves. It's actually the pre-collision system switch. When using adaptive cruise control while driving, just press it to activate—very convenient. If you can't find it on the steering wheel buttons, it might be in the settings menu on the central display. Navigate to Vehicle Settings → Safety Features → Radar Assistance to control the switch. Avoid adjusting the switch while driving at high speeds to prevent accidentally disabling safety features. During regular maintenance, check if the button contacts are clean to avoid dust-related malfunctions. If the switch doesn't respond, don’t panic—it could be a system glitch. Try turning the car off and restarting it first; if the issue persists, visit a 4S shop. Overall, the design is quite reasonable—simple but requires some familiarity with the controls.
