What are the reasons why the Peugeot 408 cannot start?

Dead battery, incorrect gear position, lack of antifreeze, etc. Here are the detailed explanations: 1. Dead battery: This may be caused by leaving the headlights on for an extended period or the battery reaching the end of its lifespan. It is generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also lead to vehicle circuit failures. Checking for a dead battery is simple—just press the horn. 2. Incorrect gear position: For automatic transmission vehicles, the gear must be in P or N position to start. If it is in R or D position, the engine will not start. Some manual transmission vehicles also require the clutch to be depressed to start. 3. Lack of antifreeze: Some car owners use water or low-quality antifreeze, which can cause the entire cooling system to freeze in extremely cold winter conditions. This can lead to a cracked engine, preventing the car's water pump from functioning, making it impossible to start the engine, and damaging other engine components.
