The reason automatic cars have three pedals is to facilitate braking. The extra pedal in an automatic car is not a clutch pedal, but a parking brake pedal. The specific reasons and functions of the foot brake are as follows: Reasons for three pedals in automatic cars: From left to right, the pedals in an automatic car are the parking brake pedal, the service brake pedal, and the accelerator pedal. The extra pedal is the parking brake pedal, designed to make braking more convenient for the driver. Essentially, it replaces the function of the handbrake with a 'foot brake.' Pressing the parking brake pedal engages the parking brake, and pressing it again releases the brake. Functions of the foot brake: The foot brake is essentially a relocated handbrake, serving the same purpose—used for long-term parking.

What transmission does the Touran use?

The Touran is equipped with a 7-speed dual-clutch transmission. This model series uses a 1.4-liter turbocharged engine across all variants, and the dual-clutch transmission is particularly well-suited for pairing with small-displacement turbocharged engines. The dual-clutch transmission is currently a highly popular type of transmission, developed based on manual transmissions. Its structure is quite similar to that of a manual transmission, with the main difference being that the dual-clutch transmission has one additional clutch and an extra set of gear-shifting control mechanisms. In a dual-clutch transmission, one clutch controls the even-numbered gears, while the other clutch manages the odd-numbered gears. This type of transmission connects to the engine via clutch plates, resulting in relatively high transmission efficiency.

How to Unlock a Locked Engine?

Solutions for a locked engine: At this point, simply use the key to unlock it. Generally, aftermarket keys may not be recognized as effectively. If the original key also fails to unlock, disconnect the negative terminal of the battery for a period of time. Wait for the engine's protection data to clear, then reconnect the battery. It usually takes about 10 seconds of disconnection before reconnecting. Reasons for engine lock due to external factors: If the engine is locked due to a collision causing it to sink and lock, repairs are necessary, and the lock will be released once fixed. If the lock is due to the computer system detecting non-system certified components, it is recommended to visit a 4S shop or a qualified repair center for unlocking.

Why does the engine squeak when cold but not when hot?

Cold engine squeaking while hot engine remains quiet is mainly caused by poor sealing of engine valves, inadequate lubrication; overly tight belts or bearing noise. If abnormal noises persist after the engine warms up, it is recommended that the owner promptly visit a repair shop for inspection to identify the specific cause. When a car is parked for more than a day, the engine's lubricating oil basically all flows back to the oil pan. During a cold start, the oil pump cannot immediately establish oil pressure or form an oil film between components, especially in the cylinder head and internal valves, which do not receive lubrication during a cold start. Whether it's hydraulic lifters or mechanical rocker arms, there will be some valve clearance, leading to a tapping noise. After the engine runs for a while, oil pressure is established, the oil film forms, and the oil temperature rises. Once the engine operates normally, the tapping sound disappears, which is a normal condition.
