Why does the car still roll when in N gear?

Where is the auto start-stop switch for the Q5?

Audi Q5L's auto start-stop switch is located behind the gear lever, featuring a mechanical button. The auto start-stop function is enabled by default and can be used as soon as the car is started. To turn it off, simply press the corresponding button. Below are some related details: 1. Tips for using auto start-stop: The auto start-stop function needs to be manually turned off by the driver each time the car is started. To disable it permanently, a visit to the 4S store is required for settings adjustment. During holidays with frequent traffic congestion, it is recommended to turn off the start-stop function. The slower start may lead to being cut off by other drivers and reduced comfort. Additionally, when starting on a slope, this function should also be turned off to prevent delayed response and potential rolling back. 2. Reasons why auto start-stop may not work: The start-stop function is only activated when the battery charge is greater than 60%. When the interior temperature is below 20℃ or the exterior temperature is below 4℃, or when the engine has not reached the standard operating temperature. When the steering wheel angle deviates more than 30 degrees from the central axis.

Can the Old Toyota Reiz Use 92 Octane Gasoline?

According to the official vehicle manual recommendation, the old Toyota Reiz should use 92 octane gasoline. In addition to checking the suitable gasoline grade in the vehicle manual, the old Toyota Reiz can also refer to the label on the fuel tank cap. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should choose 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should opt for 95 octane gasoline. However, with the application of new technologies, the gasoline grade cannot be solely determined by the compression ratio. Even high compression ratio engines can be tuned to use lower octane gasoline, as factors like ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline octane number, the higher the octane value and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the old Toyota Reiz occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane value will alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Due to the significantly lower octane value, the gasoline's ignition point decreases, causing premature ignition during the compression stroke. If combustion occurs before the spark plug ignites, resistance will arise during the upward stroke. This resistance makes the engine run very unstably. Mild knocking only increases noise without obvious engine damage, but noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and even cylinder scoring in severe cases.

What is the reason for the windshield washer fluid not spraying but the wipers still working?

The reasons why the windshield washer fluid does not spray but the wipers still work are: 1. The washer fluid level is too low and does not reach the standard height; 2. The washer fluid nozzle is blocked by dust; 3. The washer fluid reservoir or pipeline is frozen; 4. The fuse is blown or the motor is damaged; 5. There is high-pressure gas inside the washer fluid reservoir; 6. The washer fluid pipeline is blocked by impurities. Windshield washer fluid is the common name for automotive windshield cleaning fluid, which is a consumable item in vehicle use. High-quality automotive windshield washer fluid is mainly composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. During nighttime driving, windshield washer fluid helps maintain excellent transparency of the front windshield and also features quick snow and ice melting, anti-glare, and anti-fogging properties, playing a significant role in improving driving safety.

What is Level 4 Autonomous Driving?

L4 autonomous driving belongs to "high automation". Except for certain special circumstances, it generally does not require human intervention. Autonomous vehicles that rely on specialized maps for operation fall under Level 4 autonomous driving. As long as there is a map, these vehicles can achieve complete autonomous driving without human intervention, but they cannot drive autonomously everywhere. The five levels defined by SAE are: 1. L0: The driver has full control of the vehicle with no automation capabilities. 2. L1: The automated system can sometimes assist the driver with certain driving tasks, such as highway automatic cruise control (automatic lane recognition) and some driver assistance functions. 3. L2: The automated system can complete certain driving tasks, but the driver must monitor the driving environment, complete the remaining tasks, and be ready to take over if issues arise. In most scenarios, there is no autonomous driving capability, only functions like advanced automatic parking and automatic following. Many high-end vehicles currently have these capabilities, but they are far from being widely adopted. 4. L3: The automated system can both complete certain driving tasks and monitor the driving environment under certain conditions, but the driver must be prepared to regain control. This is the level I will focus on today. At this level, the driver must still remain vigilant and ready to take back control of the vehicle at any time. 5. L4: The automated system can complete driving tasks and monitor the driving environment under specific conditions and within certain environments. At this stage, within the operational scope of autonomous driving, all driving-related tasks are completely independent of the driver and passengers. However, the cockpit still seems essential, and manual control components cannot be entirely removed. 6. L5: The automated system can complete all driving tasks under all conditions. As the name suggests, humans can simply be passengers, with the steering wheel, accelerator, brake, etc., all removed. Of course, for safety and emergency situations, there should be an emergency stop button or operation. All other aspects are handled by the vehicle, with humans serving only as passengers.

What does automatic parking mean?

Automatic parking means that the driver only needs to control the throttle, brake, and gear shifting, while the system can take over the steering wheel at any time to stop the system function. The working principle of automatic parking is to perceive environmental information through the sensor system, obtain effective parking space information and the relative position of the vehicle based on the sensor system's data, and then determine the initial parking position. Cars equipped with automatic parking technology generally have devices such as ultrasonic sensors, radar, and cameras. The radar or ultrasonic sensors can measure environmental parameters and provide them to the system. After evaluation, the system finds an available parking space. The radar or sensors installed around the car can measure the distance and angle between the car body and surrounding objects. Then, the system calculates the operation process and adjusts the steering wheel rotation in coordination with the vehicle speed. The driver only needs to control the speed or even perform no operation at all.
