Windshield Features Identification

Not all windshields are built the same. Over the last decade, there have been many enhancements to a vehicle’s safety features. Not everybody knows it, but most of these new technologies are actually installed onto your vehicle’s windshield.

When you need your windshield replaced, it is vital to know which features your vehicle has. This is a problem we face every day, and the solution isn’t very simple. The different features are usually part of your rear-view mirror(not to be confused with side-view mirrors) and tucked away behind an electronic components box.

This page meant to help you identify which features you may have on your vehicle. This will help us to give you an accurate price.

Possible features your vehicle may have:

  • Rain Sensor
  • Light Sensor
  • Condensation Sensor
  • Lane Departure Warning System (ADAS)
  • Forward Collision Sensor
  • Heads Up Display (HUD)
  • Heating

Nearly all vehicle manufacturers have engineered new safety features, most of which are located on your windshield.

Your windshield can come loaded with a handful of different features that you may not even know of.

These features were once a luxury to have on higher-end vehicles. In the last five years, these features have started to become standard safety features.


Knowing what you have on your windshield is important if you ever need to get it replaced.

At Top Auto Glass, we try our best to identify which glass you have. Sometimes this is a difficult task as your vehicle may have 5 or more different windshields to choose from.

The difference is in the features you have.

In order to install the right windshield for you, we need to know exactly which features you have.

Please take a moment to identify which features you may have.

Rain Sensor

The rain sensor is a small gel pad that detects raindrops on your windshield. If triggered, it will automatically turn on your windshield wipers. It can detect on strong and how frequent the raindrops are, then adjust the speed of your wipers accordingly.

Rain sensors are common in most European vehicles. It is commonly found in most BWM, Audi, and Volkswagen.

Lane Departure Warning System

Lane Departure Warning is meant to alert you if your car is drifting out of its lane. This is to help drivers combat highway hypnosis and drifting. If you have exceeded a certain speed and are changing lanes without signaling a lane change, it will beep to alert you.

The lane departure warning system is a camera that is mounted to your rear-view mirror (on your windshield).

Lane Keep Assist

Lane keep assistance works very similarly to lane departure warning. The difference is that lane keep will not only alert you of drifting, but will also correct your vehicle’s direction by taking control of your vehicle. It will do its best to keep your vehicle within the current lane you are driving in.

Forward Collision Assist

Forward collision assist is to prevent you from rear-ending the vehicle in front of you. A sensor detects how close you are to the vehicle in front of you as well as the speed of both vehicles. It will calculate the likelihood of an accident, then take over your braking system. If you get too close to the vehicle in front of you, your car will automatically slow down to avoid collision.

Light Sensor

A light sensor is built to automatically turn on your vehicle’s inside lighting as well as headlights. If it is dark enough outside, your vehicle will do its best to decide what type of lights need to be turned on or off.

Condensation Sensor

Condensation is a big culprit for foggy windows. The best way to deal with condensation is to turn on your vents and choose between hot or cold air depending on your environment. A condensation sensor will know exactly how to deal with a build-up of condensation on your windshield.
