Can You Still Drive When the Exhaust Controller's Yellow Light Is On?

You can still drive when the engine warning light (yellow) is on, but you should get it checked as soon as possible. The engine fault signal is issued by the ECU (Engine Control Unit), which controls all electronic components of the engine, including the electronic throttle, fuel injectors, alternator, fuel pump, etc., covering systems such as intake, exhaust, fuel, ignition, and timing. If the engine fault light is on, it is essential to have it inspected at a nearby repair shop. Most modern vehicles are equipped with two oxygen sensors, located before and after the catalytic converter, and the faulty one should be identified and replaced promptly. Generally, there are three main reasons why the exhaust controller's abnormal light may illuminate: 1. Code Fault: A fault code is reported, but the system operates normally. This could be due to an operation that temporarily exceeded the ECU's control range. The fault code can be cleared first, and then you can check if it reappears. 2. Intake Pressure Sensor Fault: Based on ECU diagnostics and further inspection, a fault may be detected that does not significantly affect normal driving or has minimal impact. This indicates an issue with the intake pressure sensor, which should be addressed promptly. 3. Oxygen Sensor Fault: If driving is severely affected, causing abnormal engine operation, this is likely due to an oxygen sensor problem, requiring immediate repair.

What does it feel like to change from 195 to 205 tires?

Many car owners who have changed from 195 to 205 tires report that the car feels more stable, with no significant improvement in handling, increased fuel consumption, and some loss of power. Things to note: After widening the tread, it is necessary to check whether the tires will rub against the fenders. If they do, you need to switch back, otherwise there will be certain safety hazards. Advantages and disadvantages of changing from 195 to 205 tires: 1. Advantages: Changing from 195 to 205 tires essentially widens the tire tread. A wider tire can indeed provide better grip performance and lateral force, which greatly helps with vehicle stability. Even during aggressive driving or sharp turns, you can have sufficient driving confidence. 2. Disadvantages: At the same time, due to the increased contact area, the friction coefficient is relatively higher, which can affect the car's fuel economy and even result in louder noise at high speeds. Therefore, to achieve more balanced tire performance, it is best to choose the optimal tire width that corresponds to the wheel hub.

What Type of Driver's License is Required to Drive an RV?

Driving an RV requires the following types of driver's licenses: 1. For self-propelled RVs with a length of 6m or more or seating capacity of 20 or more, an A1 license is required; 2. For self-propelled RVs with a length of less than 6m or seating capacity between 9 and 20, a B1 license is required; 3. For self-propelled RVs with a length of less than 6m or seating capacity of 7 or fewer, a C1 license is required; 4. For towable RVs with a length of 6m or more and a total weight of 12,000kg or more, an A2 license is required; 5. For towable RVs with a length of 6m or more and a total weight between 4,500kg and 12,000kg, a B2 license is required; 6. For towable RVs with a length of less than 6m and a total weight of less than 4,500kg, a C1 license is required.

Can You Drive with Low Coolant Level?

Driving with low coolant level is not advisable. Continuing to drive under such conditions will cause the engine temperature to rise progressively without the cooling effect of the coolant, potentially leading to engine damage. Vehicle owners should regularly inspect the car's cooling system and the remaining coolant level. If insufficient engine coolant is detected, it should be replenished promptly. Coolant prevents freezing during cold seasons, which could otherwise crack the radiator or damage the engine cylinder block. Its primary function is to maintain the operating engine within a normal temperature range, providing cooling when the engine overheats. Additionally, engine coolant offers anti-freeze, anti-corrosion, and anti-scale properties.

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.
