Connect the positive terminal of the discharged vehicle's battery to the positive terminal of the assisting vehicle's battery, then connect the negative terminal of the assisting vehicle's battery to the negative terminal of the discharged vehicle's battery. Below is some knowledge about Cadillac: 1. Brand Introduction: Cadillac, a world-renowned luxury car brand under General Motors, was born in 1902 (the Year of the Tiger) in Detroit, known as the Motor City of America. Over the past century, Cadillac has created numerous firsts in the automotive industry and set many luxury car standards. It can be said that the history of Cadillac represents the history of American luxury cars. 2. Logo Introduction: The famous wreath and shield emblem chosen by Cadillac symbolizes its leadership in the automotive industry.

I often help friends deal with this situation. If a Cadillac breaks down, the first reaction is to find jumper cables. It's important to open the hood and locate the positive and negative terminals correctly; the battery is usually hidden on the left side of the engine compartment or in the trunk. When getting a jump from another car, attach the red clamp to your battery's positive terminal and the black clamp to the negative terminal of the rescue vehicle or a metal part of its body. Start the rescue vehicle, rev the engine a bit, wait for 5 minutes, and then try starting yours. Once it starts, don't rush to turn it off. If you don't have jumper cables, check if there's an OnStar system; pressing the red emergency button can call for official assistance. It's most convenient to keep an emergency power supply in the car—about the size of a cigarette box, it can be plugged directly into the cigarette lighter socket to start the car.

As an experienced driver, I recommend checking the battery condition first. If the dashboard lights are dim when turning the key to the ignition position and you only hear a clicking sound when starting, it's likely a dead battery. For manual transmission cars, you can try push-starting by engaging second gear, pressing the clutch, having someone push the car, and releasing the clutch while giving gas when speed builds up. However, this won't work for most Cadillacs as they're automatic. When jump-starting, ensure the cable clamps fully contact the battery terminals - don't panic if sparks appear during connection. The rescue vehicle should maintain around 2000 RPM for better charging efficiency. After starting, let the engine run for at least half an hour to recharge the battery, and check if the battery inspection window has turned black.

The safest and most worry-free solution is to contact the 4S dealership directly. Cadillac's factory roadside assistance is quite efficient—after providing the vehicle model and color, the rescue vehicle usually arrives within half an hour. The technician will bring a professional battery tester to determine whether it's simply a dead battery or due to battery aging. If the battery has reached the end of its lifespan, they’ll replace it directly. Although the factory battery is expensive, it can last four to five years. Attempting to jump-start the car yourself risks reversing the polarity, which could damage the ECU and create bigger problems. Remember not to jump-start in an enclosed garage, as exhaust fumes can accumulate and pose a serious hazard. After starting the car, check the dashboard for any warning lights, especially for the electronic parking brake and start-stop system, as these are prone to triggering alerts.
