The warning triangle for the BMW 3 Series is generally located on the trunk lid. How to use the warning triangle: Open the trunk lid and locate the red rectangular box containing the warning triangle on the inner side of the trunk lid; after taking out the warning triangle, extend all its legs to prevent it from tipping over. During the day on general urban ring roads, place the warning sign 50 meters behind the vehicle. If the vehicle breaks down on a city ring road at night, the warning sign should be placed 100 meters behind the vehicle. Car warning triangle: It is a warning sign, typically used when a vehicle breaks down and needs to stop temporarily on the highway, placed 50 to 100 meters in front of or behind the vehicle.

As a long-time BMW owner, I can definitely speak about the triangle warning sign placement in the 3 Series. For the sedan version, you need to open the trunk and lift the floor panel cover - you'll find the triangle sign neatly nestled in a foam cutout, making it easy to retrieve. The Touring (wagon) version is even more thoughtful, with the triangle sign secured in a small storage compartment on the left side wall of the trunk. Never just bury it under random items in the trunk! In case of an emergency after turning on your hazard lights and exiting the vehicle, immediately unfold the triangle sign and carry it at least 150 meters behind your car. Position it with the reflective side facing approaching traffic. Safety first - remember to keep a reflective vest in your glove compartment too.

Last time I helped my friend find the warning triangle for his G20-generation 3 Series, I remember it very clearly. First, open the trunk, and you'll see a handle or small indentation on the floor panel. Lift the floor panel firmly to reveal the folded warning triangle embedded in the foam storage compartment, which comes in a semi-rigid case. For the Touring version, there's a hidden compartment on the left side. When retrieving the warning triangle, be mindful of its foldable design—extend all four legs to ensure stability. In case of an accident on the highway, place it at least 150 meters away, and on urban expressways, no less than 50 meters. It features high-intensity reflective strips, and proper placement at night is crucial for safety.

The location varies across BMW 3 Series models. For the sedan version, simply lift the trunk floor panel - the rectangular plate with a handle reveals it when opened. In the touring version, it's secured in a dedicated slot within the left-side storage compartment with mesh pockets in the trunk. Remember to fully extend and lock all four support legs when using the warning triangle, with the reflective surface facing oncoming traffic. Safety regulations require placing it at least 150 meters behind a disabled vehicle.
