What Will the Dashboard Display When the Car Battery Is Dead?

[Cardoso]

When the car battery is dead, the vehicle's onboard computer display or central control screen will show a low battery warning. However, this feature is mostly available in luxury cars; ordinary family cars typically do not alert the driver about low battery levels. Methods to Deal with a Dead Car Battery: Jump-starting: Remove the clips from the battery box to open the battery cover, exposing the positive and negative terminals. Take one jumper cable and connect one end to the positive terminal of the dead battery and the other end to the positive terminal of a charged battery. Take another jumper cable and first connect it to the negative terminal of the charged battery, then connect the other end to the negative terminal of the dead vehicle. If the battery is within its normal lifespan, after a successful jump-start, drive continuously for at least half an hour to restore normal functionality. Alternatively, using a car emergency jump starter is similar to using a power bank. Attach the corresponding positive and negative clamps to the battery terminals, turn on the power switch to activate the power supply, and then start the rescued vehicle. Seek help from an auto repair shop or insurance company: If there is no other vehicle available for a jump-start, you can contact an auto repair shop, which usually has specialized batteries for rescue purposes. However, they charge based on the distance. If your insurance company offers free roadside assistance, you can request their help. Push-start method (only for manual transmission cars): This method is only applicable to manual transmission cars. Gather several people to push the car and start it. Once the car reaches a certain speed, shift into gear and quickly release the clutch pedal while applying the throttle. Once the engine starts, quickly press the clutch pedal again and control the throttle to prevent stalling, then slowly pull over to the side. Towing: As a last resort, you can tow the car. First, find a sturdy tow rope and securely fasten it between the two vehicles. Start slowly, ensuring both vehicles maintain the same speed, and pay attention to road safety. If another vehicle approaches from behind, promptly notify the towing vehicle and slowly pull over to the roadside.
