The front radar obstruction warning message is put in place to inform the driver that there is an issue with the sensor and that it is currently unavailable, so you need to have it fixed. However, if the message keeps coming on for no reason, it is possible to turn it off.
It is important to know why the obstruction radar is on as this gives a clue on how you can turn it off. The reasons vary widely from a faulty sensor to simple obstruction by snow or dirt. But if you check and find that the sensors are clean, then it could mean there are faulty or could be a wiring problem. This will require you to have it repaired or replaced.
This article explains more about the front radar obstruction and what you can do to fix the situation.
How to Turn off Front Radar Obstruction on Nissan Altima
Among the safety features included in the newer Nissan models is the front collision warning system. This system is made up of several sensors located on the front bumper of the vehicle and works to measure the distance between your vehicle and the one ahead and measure both speeds to prevent a potential collision.
The front radar obstruction warning message can display on your information screen for many different reasons.
If you want to disable the front radar obstruction warning, you will first have to determine its root cause. If the issue is a broken sensor, it is important to have it repaired or replaced as soon as possible. However, if it is only obstructed by dirt, debris, or snow, careful cleaning of the sensors will do the trick.
Why Does My Car Say the Front Radar Is Blocked?
The front radar sensor in your car is used to detect potential obstacles in the road ahead. If the radar is blocked, then it will not be able to perform this function optimally and cannot prevent potential accidents. When the radar is blocked, it will inform you on the information display. Different reasons could lead to blocking the front radar.
What Can Happen if the Front Radar Sensor Is Blocked?
There are potential causes that can arise if your front radar is blocked.
False Alerts From the Collision Warning System
The blocked radar is often not able to properly detect the distance between your car and the one ahead. Therefore, this can lead to false alerts from the collision warning system and is usually annoying and distracting. If you experience this, ensure that you take your car to a mechanic for repair.
Difficulty With Adaptive Cruise Control
Some of the newer car models come with an adaptive cruise control system that also relies on the front radars to maintain a safe following distance. If the front sensors are blocked, it may hinder the cruise control from performing its functions making it less effective.
Poor Performance From Lane-Keeping Assist
Another feature that uses the front radar sensors is the lane-keeping assist. A blocked radar makes this feature not work at all. This makes it challenging to stay in your lane.
Increased Fuel Consumption
A blocked radar sensor also has an impact on the engine. It causes it to run less efficiently. This leads to higher emissions and increased fuel consumption.
Does the 2019 Nissan Altima Have Forward-Facing Radar?
The 2019 Nissan Altima comes equipped with a predictive forward collision warning system. This system comes with a radar sensor that is fitted on the front of the vehicle that works to measure the distance to a second vehicle ahead in the traveling lane. It helps to alert the driver in case of sudden braking of the vehicle ahead and if both vehicles are dangerously close.
This system is designed to operate at speeds above 5kph. In case of a potential risk of forward collision, it alerts the driver by illuminating an orange warning light and a front radar obstruction warning message appears on the vehicle information display.
FAQs
Final Thoughts
The front radar sensors are a great addition to modern cars. Thankfully, it is possible to troubleshoot any of its related issues and turn off the front radar obstruction warning. This information can apply to the 2018 Nissan Altima and many other Nissan models.
