According to the characteristics of the Jetta model, the speed limits for each gear during the test are as follows: 1. 1st gear: 0km/h----18km/h. 2. 2nd gear: 11km/h----33km/h. 3. 3rd gear: 15km/h----44km/h. 4. 4th gear: 20km/h----60km/h. 5. 5th gear: 32km/h----100km/h. The specific details are as follows: 1. Maintaining gear speed: During the test, it is necessary to keep the speed within the above range for each gear, and the RPM should be maintained between 700 RPM/S and 2500 RPM/S. Follow the principle of one gear per clutch, and after fully releasing the clutch, the gear must remain stable for more than 3 seconds before the next gear shift operation. 2. Cancellation of fixed gear shifting items: The fixed gear shifting items are canceled. It is sufficient to reach the sub-high gear (4th gear) and achieve a speed of 35km/h throughout the test.

What causes the dashboard lights to stay on after locking a classic Focus?

If the dashboard lights remain on for a short period of about 10 to 15 minutes, this is a normal phenomenon. This is because the model is equipped with a power-off delay device, and the dashboard lights will turn off after a certain period of time after the car is locked. Once the dashboard lights go out, the various components of the vehicle's electrical system enter a dormant state, and the power consumption becomes very low. If awakened during the dormant process, the system can quickly respond. The reasons for the dashboard lights staying on are as follows: 1. Power-off delay device: The power-off delay device inside the dashboard or the combination instrument itself may have issues, preventing the vehicle from entering the dormant state. 2. Active components: There may be components in the vehicle that remain active, preventing the system from entering the dormant state. In such cases, the current consumption will be very high. If the lights do not turn off or remain on for an extended period, it is necessary to drive the vehicle to a repair facility. First, check the fault codes in the vehicle's electrical system, and then conduct a leakage test on the vehicle to confirm the cause of the fault.

What is the wading depth of the classic Focus?

The maximum wading depth of the classic Focus is 500mm. The wading depth of the classic Focus is determined by the height of the vehicle's chassis, which is the ground clearance listed in the vehicle's parameter configuration table. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when driving through waterlogged roads. Therefore, in terms of safe wading depth, off-road vehicles and SUVs have obvious advantages. However, for most compact cars and small cars with low chassis, the position of the vehicle's air intake should be used as a benchmark when passing through waterlogged roads. If the air intake of the classic Focus is below the water level during wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it will cause severe damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth must not exceed the height of the engine's air intake. Installing a snorkel can also increase the height of the engine's air intake, thereby improving the maximum wading depth. If wading is unavoidable, the following safe and correct operations should be performed: Before wading, always turn off the auto start-stop function to prevent the engine from automatically restarting after stalling in water, which could cause severe damage due to water ingestion. Assess the underwater road conditions based on the passage of vehicles ahead and choose an appropriate entry point. Follow the path taken by other vehicles and drive slowly at a steady speed, avoiding sudden acceleration or deceleration. On roads prone to water accumulation, observe warning water level markers, trees, or reference points like the wheels and doors of other vehicles to estimate the water depth before deciding whether to proceed. Know your vehicle's safe wading depth. If the water depth exceeds half the tire height or the engine's air intake, avoid entering the water and choose an alternative route.

What is the function of the button on the gear lever of the Classic Sylphy?

Used for gear shifting. The purpose of the gear lock button: To ensure safety and prevent accidental gear engagement, which could lead to unintended forward or backward movement and cause accidents. More information about automatic transmission gear positions is as follows: 1. Gear positions N, D, R: For most automatic transmission models, shifting between N, D, and R can be done without pressing the shift button. However, when shifting from other positions, the shift button must be pressed. When shifting from lower to higher gears, the shift button does not need to be pressed. 2. Gear positions P, N: An automatic transmission vehicle can only be started when the gear is in either P or N, and the brake pedal must also be depressed. To start moving, the gear must be shifted from P to D, and the brake pedal must be pressed during this operation. 3. Coasting in N gear: It is important to avoid coasting in N gear while driving an automatic transmission vehicle. This is because the gears in the automatic transmission require lubrication, and when the gear is in N, the oil pump does not operate, preventing normal lubrication of the gears. This can cause the internal temperature of the transmission to rise rapidly, leading to irreversible damage to the transmission.

Can the Classic Sylphy Low Version Connect to Bluetooth?

Yes. First, enable the Bluetooth function on both your phone and the car. Set the device to be discoverable to everyone, then search for the car's Bluetooth device on your phone. Once found, select it to connect, enter the password, and the pairing will be completed successfully. More details about the Classic Sylphy are as follows: 1. Interior: The seating space creates a very homely atmosphere, making it very comfortable. The layered dashboard design feels like sitting on a sofa at home with a bookshelf in front, on which there is a large screen—like a big TV, truly homely. The central control screen is vibrant and clear, and the entertainment system is well-equipped. The overall space is quite spacious, with ample horizontal and vertical room. The rear seating area offers excellent legroom and knee space, complemented by wide and comfortable seats that minimize the sensation of bumps. Noise control is excellent, with barely any noticeable noise at 60 km/h. 2. Storage Space: The central control area has been downsized. While it should accommodate many items, it doesn’t. There are only two cup holders in the central control area, positioned quite far back. The front area lacks a compartment for tissues or a box, with only a small space for a phone on the front door.

Does the Classic Sylphy have drainage holes under the chassis?

No. Here is more information about drainage holes: 1. Below the fuel tank cover: Since the fuel tank's sealing is not as tight as imagined, fuel may spill during the insertion or removal of the fuel nozzle. Therefore, this can also serve as an oil drainage hole. Additionally, the drainage hole here prevents water accumulation, avoiding the fuel tank cover from freezing shut in winter. 2. Trunk drainage hole: Generally located near the spare tire, it is only needed in extreme situations like vehicle submersion. Some manufacturers may seal the trunk drainage hole before delivery, which can be punctured when needed. 3. Air conditioning drainage hole: Usually located below or in front of the passenger seat. Turn on the air conditioning and observe where water drips outside the car to locate the air conditioning drainage hole. If unexplained water accumulation is found on the passenger floor, it may be due to a blocked drainage hole causing backflow, which can be cleared with thin wire.
