Here is an introduction to the hidden features of the 2021 Corolla: Anti-glare rearview mirror function: This feature is only available on the top and second-top hybrid models of the Corolla. During nighttime driving, when encountering a vehicle behind using high beams, pressing the small black button in the middle of the lower part of the rearview mirror can achieve an anti-glare effect without adjusting the mirror angle. Window lock function: For safety reasons, parents often place their children in the back seat, thinking it is safe. However, this can still pose risks, as children might play with the window controls, sticking their hands or heads out of the window. Pressing the window lock button can lock all windows except the driver's side. Adjustable sun visor: By releasing one of the open latches, the sun visor can be rotated toward the window to block sunlight from the side. Some models even feature a dual sun visor design, effectively blocking sunlight from both the front and side, making it highly practical.

After a year of driving the 2021 Corolla, I discovered some hidden features that turned out to be incredibly practical. For instance, the key fob: holding the lock button automatically closes all windows including the sunroof—a summer parking lifesaver. Double-pressing the unlock button releases all door locks, making family outings with kids much smoother. In the driver's seat, activating the diagnostic mode by holding the left steering wheel button for seconds reveals vehicle status like tire pressure history. The wipers have an adjustable height feature for improved rainy-day visibility. Climate control vents come with directional knobs allowing precise airflow to face or feet only. The audio system's hidden 'sound stage center' adjustment in settings significantly enhances in-car music experience. Safety-wise, automatic door locking after parking is a thoughtful touch in crowded areas. These unadvertised features dramatically improve daily convenience.

As a mechanic buddy who frequently works on Corollas, I must say the 2021 model has some nice hidden features. For example, regarding the engine: through the dashboard diagnostic mode, I can check the generator voltage adjustment settings to avoid electrical overload. Holding down the unlock button on the key can open all windows, quickly ventilating and defogging the car. The wiper switch has hidden adjustment options to change the intermittent speed, adapting to different rain conditions. The air conditioning system has a memory position function, allowing me to preset temperature and fan speed, which remain unchanged upon restart. Entering the multimedia screen settings and holding certain buttons can access the engineering mode for fine-tuning Bluetooth pairing or brightness. Safety-wise, the door locks come with enhanced child safety lock features to prevent kids from accidentally opening doors. These features make my maintenance work more efficient.

The hidden features of the 2021 Corolla I tried are pretty cool. Pressing the key twice unlocks all doors for quick entry. Access the special diagnostic menu on the dashboard by holding the steering wheel button to view tire wear warning data. The side of the wiper switch allows for fine-tuning its position to avoid scratching the glass when parked. The air vent angle lock knob enables directional airflow without blowing directly at people. Adjusting the sound field balance enhances immersive audio while driving. The auto-lock feature ensures safety by automatically locking the doors while driving. Other features like memory seat settings allow quick return to preferred positions.

What does it mean to downshift by two gears?

Downshifting by two gears refers to shifting directly from fifth gear to second gear, but in this case, it fails to successfully decelerate the vehicle and may instead cause the transmission gears to break. Therefore, when performing emergency downshifting, it is necessary to downshift step by step to minimize damage to the vehicle. The relevant details are as follows: Based on road conditions and vehicle speed, control the steering wheel properly, quickly press the accelerator pedal, and shift from a higher gear to a lower gear. Simultaneously, engage the handbrake, but avoid pulling it too tightly or holding it continuously, as this may cause the brake disc to "lock up," damaging the transmission components and losing braking capability. Also, do not pull it too loosely, as this may lead to excessive wear and overheating of the brake disc, resulting in loss of braking function. During the moment of upshifting, the engine speed drops immediately, but the vehicle speed remains unchanged. At the same time, due to the reduced transmission ratio, the torque output from the engine to the wheels also decreases. After completing the upshift, the vehicle accelerates by pressing the accelerator pedal, but due to the reduced torque output, the acceleration is relatively slow. Conversely, during the moment of downshifting, the engine speed rises immediately, but the vehicle speed remains unchanged. Meanwhile, due to the increased transmission ratio, the torque output from the engine to the wheels also increases.

What is the function of tire pressure monitoring?

The function of tire pressure monitoring is to automatically and real-time monitor the tire pressure during vehicle driving, and to alert for tire leakage and low pressure to ensure driving safety. There are three commonly used tire pressure monitoring methods: Direct tire pressure monitoring: The direct tire pressure monitoring device uses pressure sensors installed in each tire to directly measure the tire pressure. It uses a wireless transmitter to send the pressure information from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. When the tire pressure is too low or there is a leak, the system will automatically alert. Indirect tire pressure monitoring: When the pressure of a tire decreases, the weight of the vehicle will cause the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to other wheels. By comparing the speed differences between the tires, the purpose of monitoring tire pressure is achieved. The indirect tire pressure alert system actually relies on calculating the rolling radius of the tires to monitor the pressure. Introduction to the Tire Pressure Monitoring System (TPMS): It combines the advantages of the above two systems, equipping direct sensors in two diagonally opposite tires and a 4-wheel indirect system. Compared to using only a direct system, this composite system can reduce costs and overcome the defect of the indirect system not being able to detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data of the actual pressure in all four tires like the direct system.

What Causes the Engine Warning Light to Illuminate in the T-ROC?

T-ROC engine warning light may illuminate due to the following 7 main reasons: Sensor malfunction: Sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors, when damaged, poorly connected, or with interrupted signals, prevent the car's ECU from accurately obtaining engine data, triggering the warning light. Fuel quality issues: Failure to use the fuel and engine oil as specified by the manufacturer may cause engine wear, leading to the warning light. Poor combustion of the air-fuel mixture: This can lead to engine carbon deposits or knocking. Detected by the oxygen sensor and reported to the ECU, the warning light will illuminate. Causes include faulty spark plugs, ignition coils, fuel pump, or clogged fuel lines. Turbocharging issues: Problems with the intake turbocharging pipeline or turbocharger can trigger the warning light. Turbocharger damage is most common, accompanied by symptoms like oil leaks, high oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake issues: Blocked engine pipes due to intake problems can cause the warning light to illuminate, especially if the air filter is dirty and not cleaned regularly. Exhaust issues: Faults in the exhaust system, such as rear oxygen sensor, catalytic converter, exhaust camshaft, or bearing failures, can trigger the warning light. The catalytic converter is most commonly affected by leaded gasoline, certain lubricant additives, physical damage, or fuel system faults. Anti-theft system malfunction: If the car's electronic anti-theft system fails or the anti-theft controller is incompatible with the engine ECU, the engine may not operate correctly, and the warning light will illuminate. Steps to address the engine warning light: First, check if the engine is running normally, looking for signs like shaking or black smoke. Avoid restarting if these symptoms are present, especially if the light is red. If the engine can start, turn it off for 5-10 minutes, then without pressing the brake, press the start button or turn the key halfway to the 'on' position. The car will perform a self-check; observe if the warning light turns off after 5-10 seconds. If the light remains on, visit a service station promptly. Technicians can use a diagnostic tool to read fault codes and perform targeted repairs.

What are the long-term effects after repairing an engine that has taken in water?

After repairing an engine that has taken in water, the long-term effects are as follows: 1. Water immersion: If the vehicle was only immersed in water and then towed to a repair shop (without starting the engine), this generally does not cause irreversible damage to the engine. The main task is to clean the accumulated water inside the engine, but the extent of cleaning depends on the situation. More often, the intake pipe and intake manifold are removed, and compressed air is used to dry the water inside. In this case, there are usually no significant aftereffects. If you are concerned about aftereffects, you can replace all necessary parts. 2. A small amount of water entering the cylinders: In many cases, the owner is unaware that the engine has taken in water, and coincidentally, the amount of water is small (enough to allow the engine to start). If the owner chooses to continue driving at this point, the final consequence could be the piston seizing in the cylinder, with the connecting rod bending or breaking due to the immense pressure. A more severe scenario is the broken connecting rod piercing the cylinder block directly. At this stage, the engine may require major repairs or even be scrapped, and it might leave aftereffects such as shaking, reduced power, and frequent malfunctions. 3. A large amount of water entering the engine cylinders: This might seem the most severe, as the common belief is that more water causes more damage to the engine. However, in reality, when the cylinders are filled with a large amount of water, the engine crankshaft cannot rotate at all. Since water is incompressible, the piston has almost no room to move upward. At this point, even if the ignition switch is turned on, the starter motor cannot rotate, meaning no further damage is caused to the engine. Nevertheless, the engine will likely need major repairs at this stage.
