The Lane Departure Feature Explained

Before we go ahead, we should quickly explain the lane departure feature. This feature is also known as the lane departure alert and it detects when your car leaves its original lane. The system can also detect if this was an intentional act by the driver or not.

Many drivers consider this feature as the “assistant driver.” When the system discovers that the car is leaving its lane unintentionally, it informs the driver. It does this through an audio warning. In some RAV4 models, the system can take over the steering and move the car back to the right lane. This button is located on your car’s steering wheel.

Now that you have an idea of what the lane departure feature is and how it works, let’s discuss some problems.

Toyota RAV4 Lane Departure Not Working: Possible Reasons and How to Fix

The lane departure in your RAV4 presents you with several safety benefits. Considering how beneficial this system is, one can be distraught when it doesn’t work. What are the reasons behind this system not working? How can you fix the issue? We will discuss all of this in this section.

Feature is not activated or it is mistakenly deactivated

The lane departure alert is not activated by default. As such, you must activate it to enjoy the benefits. One of the major reasons why the lane departure feature is not working is that it is not activated. Activating this feature is very easy since the button is located on your steering wheel. Take the following steps to activate the lane departure feature:

Step 1 – Look at your steering wheel to locate the lane departure alert button.

Step 2 – Press this button to activate the feature. You should see an indicator light on the dashboard after doing this. This light shows that the feature is activated.

Step 3 – If you want to activate the “Steering Assist” feature, tap on the settings menu on your dashboard. Note that the “Steering Assist” feature works with the lane departure feature.

Step 4 – After opening the settings menu, tap on the Steering Assist menu to turn the feature on.

Since a button is responsible for activating or deactivating the lane departure feature, it is very easy to deactivate it accidentally. Once you notice that the feature isn’t working, the first thing to do is to check if you have mistakenly deactivated it. All you need to do is to check the dashboard to see if the indicator light is on. If it isn’t, then follow the steps above to reactivate it.

Fuse issues

What if you have tried activating the feature and it doesn’t still come on? It is possible that the problem may be electrical. One of the most important components of your car is fuses. They may seem so small but they are the heart of every electrical circuit in your car.

A fuse breaks the electrical circuit if there is an electrical surge that can damage the associated electrical component. How do you know if your lane departure feature stopped working because of a fuse problem? Simply check the associated fuse. Follow these steps to do this:

Step 1 – Locate the fuse box and check the fuse map to find the fuse associated with the lane departure feature.

Step 2 – Check if the fuse is properly fixed or not. If it isn’t, you can take it out and fix it properly.

Step 3 – Follow the steps above to activate the feature again. Now, check if it is working or not.

Step 4 – If the feature is still not working, then you should check the associated fuse for damage. A simple visual evaluation is all you need. If you notice that the fuse is broken or the wire has cut, simply replace it.

After doing this, you should activate the feature again. If it doesn’t work, try the next solution.

Wiring problems

The lane departure feature in your RAV4 is controlled by an electrical circuit. This implies that if the feature is still not working after all the fixes above, there could be underlying electrical problems. It could be that the circuit is broken somewhere or one of the wires is disconnected.

Tracing the electrical circuit is quite complicated and we don’t advise you to do it without some form of experience. We suggest that you invite your mechanic to take a look at the system. This way, they can easily locate any wiring problems and fix them.

What kind of accidents does the lane departure system in your Toyota RAV4 prevent?

To ensure that your car maintains its lane, the lane departure system makes use of a camera. The camera monitors the lane markings on the road and informs the driver when they are veering off. Several bodies have endorsed this feature because it helps to protect you from several kinds of accidents.

In this section, we take a look at some of the accidents that the lane departure alert will protect your RAV4 from:

  • Striking a car in the next lane. The other car could be traveling in the same direction or an opposite direction.
  • Vehicle rollovers which could occur when your car leaves the road completely.
