Why Can't the Car Start and the Brake Pedal is Hard to Press?

1 Answers

The reason why the car can't start and the brake pedal is hard to press: The car's inability to start causes the brake pedal to be hard to press, so the car won't start, but it's not due to a fault in the brake system. This is because the car's braking system relies on a hydraulic system, which requires the brake pads to be tightly pressed against the brake discs. If the driver's force is insufficient, the pedal will be hard to press. Therefore, the car's brake system includes a vacuum booster system, which uses the engine's power to assist the movement of the brake pedal, making it easier for the driver to press the brake. The vacuum brake booster system is also known as the vacuum servo brake system. The servo brake system adds a set of power-assisted devices powered by other energy sources to the manual hydraulic brake system, allowing both human power and engine power to be used as braking energy sources.

Where is the keyhole for the Nissan Tiida?

There is a slot the size of a smart key below the start button; insert the entire smart key into it. In case the smart key runs out of battery, first use the mechanical key to open the door. After opening the door, reinsert the mechanical key, then insert the entire smart key into the slot located below the start button. Depress the brake pedal and press the start button to ignite the engine. Below is more information about the Nissan Tiida: 1. In terms of appearance and interior, the new model remains largely consistent with the previous version, with the main improvements being in the technological features. The previous Tiida was already equipped with the advanced i-CONNECT smart entertainment system, and the new Tiida adds the Dongfeng Nissan "Intelligent Mobility+" connected car system on top of that. This system incorporates iFLYTEK voice recognition technology and, through collaboration with AutoNavi, provides real-time updates for online maps. It enables intelligent congestion avoidance, inertial navigation, and remote real-time monitoring. Users can remotely monitor the vehicle's status and locate the vehicle in real-time via a mobile app. 2. In terms of safety features, the new model is equipped with the NISSAN-i-SAFETY intelligent active safety system, which includes the FEB intelligent forward emergency braking system. When the vehicle is traveling between 10km/h and 80km/h, the FEB system continuously monitors pedestrians or vehicles directly ahead. If the system detects a potential collision risk, it provides early warnings through audible alerts and the TFT display on the instrument panel, and actively applies emergency braking to prevent collision hazards.
