The main hidden features of the 2021 Nissan Sylphy Classic include: one-touch window roll-up, one-touch unlocking, etc. One-touch unlocking: With the key, simultaneously press and hold the lock and unlock buttons to set the lock confirmation sound. Press and hold the trunk unlock button to automatically open the trunk. One-touch window roll-up/down: With the vehicle powered on or started, pull up the driver's side window switch until the window is fully raised and hold for 5 seconds to activate the one-touch window function. When parking and turning off the engine, the doors will automatically unlock. The Sylphy is a compact sedan equipped with a 1.6L naturally aspirated engine, delivering a maximum horsepower of 135ps, a maximum power of 99kw, and a maximum torque of 159Nm. The engine uses 92-octane gasoline, with both cylinder block and head made of aluminum alloy. It employs multi-point fuel injection and is paired with a CVT or manual transmission. Built on the CMF platform, the Sylphy leverages its core advantages of high parts commonality, flexible regional module combinations, and compatibility with multiple models for extensive upgradability, achieving comprehensive improvements in structure, space, technology, configuration, and performance.

I just bought a 2021 Nissan Sylphy Classic and discovered some of its hidden features that are really practical. Holding down the unlock button on the car key for a few seconds automatically lowers all the windows, which is super convenient for cooling down the car in hot summers. After locking the car, the headlights can stay on for a while to light up your way home—just adjust the option in the car settings. There's also a fun one: accessing diagnostic codes through the hidden menu on the dashboard. For example, pressing the ignition switch three times without stepping on the brake, then switching the dashboard buttons, can display fault information without needing to visit a repair shop. These features are thoughtfully designed, making driving smarter and safer. I think the Sylphy series does well in terms of user-friendliness, and I recommend trying out how to enable them.

I often drive this family car and have discovered its hidden features are quite safety-focused. One feature is the headlights can be set to automatically delay turning off after locking the car, providing illumination to reduce nighttime blind spot risks. Holding down the unlock button on the key fob can also roll down the windows for ventilation, preventing overheating issues inside the cabin. Additionally, through specific button combinations, the dashboard can enter diagnostic mode to display vehicle status codes—such as battery voltage or engine condition—helping identify potential problems early. These settings are tucked away in menus and require some tricks to activate, but they ensure more reliable daily driving. It's recommended to regularly check if these functions are working properly, as maintenance is straightforward.

There are some hidden tips to enhance comfort in my Nissan Sylphy Classic. For example, long-pressing the key buttons controls the window opening and closing, and the headlights staying on for a while after locking the car is very practical. The dashboard can also display hidden diagnostic information.

How to Determine the Right Side of the Car Doesn't Scrape People?

Methods to determine that the right side of the car doesn't scrape people include being skilled at using rearview mirrors and adjusting their positions properly. The specific methods are introduced as follows: Utilize Rearview Mirrors Effectively: Observing the sides, rear, and underneath the car through rearview mirrors is a good method. It's important to develop the habit of frequently checking the mirrors. Adjusting the mirrors correctly is also crucial, especially since the driver is farther from the right rearview mirror. The angle should be adjusted according to each person's seating position, which needs to be confirmed and set properly before starting to drive. Choose the Road and Lane in Advance: Try to avoid areas with heavy pedestrian traffic, such as markets, schools, large supermarket entrances, or narrow roads in old urban areas, to prevent scrapes. When driving on roads with three or more lanes, try to stay in the middle lane. The right lane often has electric bikes, bicycles, and tricycles cutting in, which tend to ride irregularly and are very unsafe. Determine the Position of the Right Front Corner: For pedestrians, when they are 20 centimeters away from the right front corner, the lowest visible point is at the waist. For other vehicles, when the distance is 20 centimeters from an obstacle vehicle, the lowest visible point is at 80 centimeters. For sedans, 80 centimeters is roughly below the door handle, while for SUVs, it's around the lower edge of the headlight. Therefore, when approaching an obstacle vehicle, ensure you can see below the door handle or the lower edge of the headlight to avoid contact.

What Are the 5 Signs That a Tire Is About to Fail?

The 5 signs that a tire is about to fail are: 1. Severe tire wear: Regardless of the tire brand, wear indicators are set in the grooves of the tread. When the tread depth wears down to the same level as the raised indicator rubber, it means it's time to replace the tire; 2. Sidewall cracks: The sidewall is the weakest part of the tire, and the cord layer provides strength. If the sidewall cord layer is damaged, there is a high chance of a tire blowout; 3. Tire aging: Over time, tires will gradually show signs of aging (tread cracks, hardened rubber); 4. Tire bulges: When the wheel receives uneven impacts, bulges may appear in certain areas; 5. Large punctures or excessive repairs: If the puncture is too large or the tire has been repaired too many times, it directly affects driving safety.

Can You Continue Driving When the ABS Light Is On?

When the ABS warning light is on, it is recommended not to continue driving, as the illuminated ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may lose control and skid, making it difficult for the driver to decelerate or adjust the vehicle's trajectory, posing significant safety risks. The ABS light can illuminate under various conditions, each with different causes and solutions, as detailed below: Condition 1: ABS warning light stays on continuously (most common). Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS control unit from determining the vehicle speed and wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt from the wheel speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Poor signal quality due to loose connections in the system wiring or poor contact in the ABS relay, leading to system failure. Solution: Inspect wiring connections and reconnect any loose parts. Condition 2: ABS warning light intermittently illuminates but turns off during acceleration. Cause: When multiple electrical devices are in use, the battery voltage drops below 10.5V. As engine speed increases, voltage rises, and the ABS light turns off. This can also occur if the ABS system's power supply voltage is too low, such as due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity, inspect the charging system, and examine the power supply (e.g., voltage relay or poor power contact). Condition 3: ABS warning light remains on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body, loose wiring connections in the ABS hydraulic valve body, or a faulty ABS control unit. Solution: Loosen and retighten the grounding screw on the hydraulic valve body, clean contact surfaces if necessary, check for enlarged connector gaps, and replace the ABS or ABS/ASR control unit if needed. Condition 4: ABS warning light illuminates during high-speed driving. Cause: The ABS control unit detects a significant discrepancy between rear and front wheel speed signals during high-speed driving, or incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, typically listed on the fuel tank cap label. Condition 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch or poor internal contact in the brake light. Solution: With the engine running, press the brake pedal, push the brake switch linkage down fully with your fingers, then release the pedal to complete the self-setting process. Replace the brake light switch if necessary.

What is the significance of wheelbase size for a vehicle?

The significance of wheelbase size for a vehicle is: Generally speaking, the higher the class of the car, the longer the wheelbase. A larger wheelbase results in a longer cabin length, providing more spacious seating for passengers and better resistance to pitch and yaw. While a long wheelbase improves straight-line cruising stability, it reduces steering flexibility, increases the turning radius, and diminishes the vehicle's maneuverability. From the perspective of vehicle component layout, the wheelbase essentially determines the position of the car's center of gravity. If one wishes to alter the wheelbase, it is necessary to redesign the layout of the vehicle's components, especially the bulky transmission system and body styling. Additionally, parameters such as the springs and shock absorbers in the suspension system must be adjusted accordingly based on rigorous testing.

Why Should You Pick Up Your Car in the Morning?

There is no rule that you must pick up your car in the morning; you can do it at any time, and there are not many specific requirements. There is no difference between picking up the car in the morning or afternoon. However, the temperature in the morning is more comfortable, while in the afternoon, the high temperature can be unbearable for everyone. Another reason is that picking up a car involves handling many procedures. If you do it in the morning, you will have plenty of time, whereas in the afternoon, you might worry about not completing the procedures on time, which could delay the pickup. When picking up your car, pay attention to the following: check whether the car is from inventory, whether there are any signs of body repair or repainting on the surface, whether the car's certificate and other documents are complete, and whether the interior shows signs of wear. Additionally, insurance purchased at the 4S store only takes effect at 12:00 AM, so drive carefully on your way home.
