Many of your vehicle's driver support features rely on data from components that scan and map your vehicle's surroundings, such as cameras, sensors and radar units. This section doesn't show all components and their precise locations, but it gives you a general idea of where they are. Areas pointed out in this section are particularly important to keep clean. Damage to these areas can also affect functions that rely on components located there.
Warning
Clean regularly
Camera, sensor and radar locations on the vehicle must be cleaned on a regular basis and kept free from labels, objects, dirt and other potential obstructions. Otherwise, vehicle functions may respond incorrectly or become less responsive or deactivated.
Scraping the windshield
The windshield area in front of the front-facing camera has its own heating to defrost and remove any build-up of snow or ice. Do not use an ice scraper on this area, as it can scratch the glass surface. Scratches or damage to the glass can interfere with or limit the camera's detection capabilities.
Mounted accessories
Be mindful of the effects of mounted vehicle accessories, such as cargo racks or exterior light accessories. The items themselves or the load you add may obstruct cameras, sensors or radar units.

Tip
Finding the parking sensors
There are multiple parking sensors along the lower edge of your vehicle. You can see their exact locations by looking for their button-like cover plates along the bumper panel.
Important
Cleaning in front of radar units
If you find dirt, snow or ice, or if the vehicle indicates that a radar unit is blocked, you should address it as soon as possible. Always clean and clear a large area around the radar units to so their full field of view is available.
