Does the Teana have a reverse radar?
3 Answers
Teana has a reverse radar. Working principle of reverse radar: The reverse radar uses the principle of animal bionics. It informs the driver of surrounding obstacles through sound or more intuitive display. It eliminates the troubles caused by the driver's need to look around when parking, reversing, and starting the vehicle, and helps the driver overcome the shortcomings of blind spots and blurred vision. It improves driving safety. Performance introduction of reverse radar: Sensitivity, whether there are blind spots, and the range of detection distance. Generally, the detection distance of a reverse radar should be 1.5 to 0.3 meters, while a good one can reach 2.5 meters. Some reverse radars have insufficient sensitivity, with a detection distance of only 1.2 to 0.4 meters, which will bring certain difficulties to the driver's judgment and measures.
I've been driving this 2022 Teana for almost two years, and those round probes on the rear bumper are particularly noticeable. When I picked up the car, the salesperson mentioned that rear radar comes standard across all trim levels, even the base model. At traffic lights, I've felt the rear bumper - the metal contacts of the four probes are clearly detectable. When reversing, the central display shows specific distance numbers, beeping starts at 1.5 meters, and the beeps get more urgent as you get closer. Last time in a shopping mall's multi-level parking space, if it weren't for the rear radar suddenly turning red with an alarm, I would have almost hit the lifting frame. I suggest you ask the salesperson to demonstrate the radar sensitivity during the test drive - it makes parking in older residential areas much easier.
With 15 years of experience repairing Nissan vehicles, I'm thoroughly familiar with the Altima's reverse radar system. The differences between old and new models are significant: the 14th-generation Altima comes standard with four rear radar sensors, while most pre-2016 Comfort editions didn't include them—it depends on whether the owner opted for installation. The sensors are hidden in the black plastic blocks on the rear bumper; you can feel the circular protrusions by hand. The key thing to watch for is what to do when the radar alarm stops working—just last week, I fixed a car whose sensor seals were damaged by a high-pressure car wash hose. If you're unsure, check the maintenance manual in your glove compartment; the parts list spells everything out clearly.
