How to reset the radar on Haval H6?

When the tire pressure light needs to be reset, if the tire pressure sensor has not been replaced, the tire pressure light will automatically turn off after driving a certain distance. Below is relevant information about tire maintenance: 1. Regularly check tire pressure: Tire pressure is an important factor affecting tire lifespan. It should not be too high or too low; inflate according to the tire pressure indicated on the vehicle. In summer, try to keep the tire pressure slightly lower; in winter, ensure the tire pressure is slightly higher than in summer due to thermal expansion and contraction. 2. Perform wheel alignment regularly: If the vehicle pulls to one side or exhibits other abnormal steering behaviors, promptly align the tires to prevent other irregularities. Wheel alignment ensures even force distribution among the four tires, avoiding excessive wear.

Last time I drove my Haval H6, I encountered a false radar alarm and spent quite a while fixing it. Find a safe place to park and turn off the engine, then open the front hood and locate the negative battery cable. Use a wrench to loosen the clamp and disconnect it. Wait about ten minutes to let the vehicle's computer completely power off and reset—don’t touch any car key buttons during this time. After reconnecting the negative cable, start the car and press the radar switch icon with a square frame on the center console. A beep sound means the reset was successful. False alarms are especially common after rain—usually caused by dirty sensors or water mist interfering with the signal. Before resetting, remember to wipe the circular radar sensors on the bumper with a wet wipe. Also, avoid using a high-pressure washer directly on the sensor areas during regular car washes.

My H6 just had maintenance done recently, and the technician showed me step by step. The most reliable method to reset the radar is to disconnect the vehicle's computer power. Open the hood, locate the battery, and use an insulated wrench to loosen the negative terminal. Wait for a complete power cut of at least five minutes. After reconnecting, start the car, shift into reverse to test the radar—this will restore the system to its default settings. A reminder: the T-shaped radar button has different functions—a short press turns the radar on/off, while a long press (10 seconds) enters calibration mode. If the radar still behaves erratically after resetting, it might be due to mud-covered sensors or loose wiring connections, which would require a professional inspection at the shop.

Last month, the reversing radar suddenly malfunctioned, and I fixed it using the power reset method. The Haval H6 automatically resets all driving assistance systems after the battery is disconnected. The specific steps are to first disconnect the negative cable, wait for ten minutes, then reconnect it and start the engine. After starting, don't rush to drive; test whether the radar distance display has properly reset by shifting into reverse while stationary. I always keep a can of WD-40 circuit protection spray in the glovebox and give the radar wiring harness connectors a quick spray after resetting. Regularly check if any of the radar sensors on the bumper are dented—once, after a scrape, a misaligned sensor caused constant false alarms. The reset operation actually saves more time than going to the 4S shop; doing it myself took just twenty minutes to resolve.

That day when dropping off the kids at school, I noticed the radar kept beeping erratically. Following the manual's instructions to reset by disconnecting the power fixed the issue. The key steps were to open the hood, loosen the negative battery terminal clamp for five minutes, and then reconnect it. This resets all the vehicle's computers, including the radar system. Make sure to turn off the engine and remove the key before performing this operation to avoid blowing a fuse. After resetting, remember to test obstacle detection from different angles by moving a cardboard box around the rear of the car to check sensitivity. Summer rainstorms can easily cause radar malfunctions, so after resetting, it's best to apply some silicone grease to the radar sensor seams for waterproofing. If you're not familiar with electrical operations, it's safer to have the dealership reset it using a dedicated diagnostic tool.

Last time when passing another car in a narrow alley in the neighborhood, the radar got stuck, and the power-off trick really worked. The reset core of the Haval H6 is to restart the onboard computer: disconnect the negative terminal of the battery for ten minutes and then reconnect it, start the car, and the reset is complete. Important reminder: turn off the air conditioning and headlights before disconnecting the power, otherwise it may trigger fault codes. Don’t panic when reconnecting the negative terminal as there will be sparks—this is normal. After resetting, drive around twice to let the onboard system adaptively calibrate, and check the paint around the radar probes while you’re at it. If there’s any damage, touch up the paint to prevent rust. In winter, freezing can also cause false alarms, so avoid parking too close to heating vents to prevent condensation on the probes.
