If the yellow light of the Roewe one-button start keeps flashing, it may be due to affected wiring contacts, a weak car battery, key sensing issues, or a locked steering wheel. The specific reasons for the flashing yellow light are as follows: Wiring Contact Issues: It could be caused by the installation of a dashcam or other electrical devices affecting the contact of other wiring, leading to the yellow light flashing. First, check the wiring and try reconnecting it. Weak Battery: If the car battery is weak, it may also cause issues with the one-button start. In this case, replacing the battery is a better option. Key Sensing Issues: If there is a strong magnetic field nearby, it can interfere with electronic devices, making it impossible to detect the key. You can point the key directly at the one-button start or quickly move away from the area. Locked Steering Wheel: A locked steering wheel is a normal anti-theft feature. This occurs when the steering wheel is turned after the car is turned off, causing the car's computer to assume a theft situation and automatically activate the anti-theft function. First, press the one-button start once, then step on the brake, turn the steering wheel, and press the one-button start again.

I recently encountered the issue of the yellow one-touch start light flashing as well. For regular drivers like us, the main reason is usually a dead key fob battery. The key fob uses a coin-type battery, which tends to drain after a year or two of use, causing the system to fail detecting the signal. You can try replacing it with a new battery—it's inexpensive and simple to do. If it's not the key fob, the issue might be that the key is too far from the steering wheel or is being interfered with by other electronic devices, such as when a phone or metal object is nearby. Sometimes, the vehicle system itself may have a minor glitch, requiring a restart—just turn off the power, wait a few minutes, and try starting again. I once had this happen due to low battery voltage, but thankfully, I got it checked at a repair shop in time to avoid travel delays. In short, this flashing light is often an early warning of a minor issue—don’t ignore it. Safety comes first, so I recommend checking before driving or scheduling regular maintenance to prevent unexpected problems.

How many liters does it take to fill up the Sylphy's fuel tank?

The fuel tank capacity of the Sylphy 1.2L model is 41 liters, the classic 1.6L model has a 50-liter tank, and the 1.6L-CVT version comes with a 47-liter tank. These figures are officially released data. The Sylphy uses 92-octane fuel. The 1.2L model has a fuel consumption of 3.9L per 100 kilometers, allowing a range of 1051km on a full tank. The classic 1.6L model consumes 5.2-6.1L per 100 kilometers, providing a range of 819-961km on a full tank. The 1.6L-CVT version consumes 4.9-5.3L per 100 kilometers, offering a range of 886-959km on a full tank. During daily driving, it's essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it's advisable to refuel when there are about 2 segments left to avoid running out of fuel midway. In actual refueling, the amount of fuel might exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safe limit. There is additional space from the safe limit to the tank opening, which is designed to allow for fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

How to Prevent Car Fires?

Methods to prevent car fires: 1. Fires usually have early warning signs, such as unusual noises or odors from the vehicle. In such cases, you should immediately turn off the engine and park the car in a sheltered area; 2. Locate the source of the fire, but avoid hastily opening the hood, as introducing air can fuel the fire. Have a fire extinguisher ready before opening the hood; 3. If the fire becomes uncontrollable, call emergency services immediately and also contact your insurance company to report the incident, obtaining a claim number or requesting an on-site assessment; 4. After the fire is extinguished by the fire department, request a fire report and an explanation of the fire cause; 5. Have the car towed to a designated repair shop as required by your insurance company and inform the insurer for damage assessment.

What causes the car to shake when accelerating from 60 to 80 mph?

The reasons for the car shaking when accelerating from 60 to 80 mph are as follows: Loose drive shaft: Check if the drive shaft (i.e., the half shaft) is loose. You can also perform a test drive to inspect. The inspection method is to release the throttle and shift to neutral at 80 mph. If it doesn't shake, it's a half shaft issue. If it still shakes, perform a four-wheel dynamic balance check to see if there is water inside the tires. Excessive gap in suspension ball joints or connecting components: When the car accelerates from 60 to 80 mph, the front body shakes, but it doesn't shake when not pressing the throttle or at other speeds. This is caused by excessive gaps in the front suspension ball joints or connecting components, which create shaking at a certain frequency. It is necessary to go to a repair shop to adjust the toe-in and front wheel alignment.

Does Using Air Conditioning While Parked Damage the Car?

Using air conditioning while parked can indeed harm the vehicle. Keeping the car idling with the AC on for extended periods leads to several issues: it increases fuel consumption, accelerates engine carbon buildup, and in poorly ventilated areas or garages, may cause carbon monoxide poisoning for occupants. Below are the specific hazards of leaving the air conditioning on while the car is parked: 1. Carbon Monoxide Production: When the engine runs, incomplete combustion in the cylinders can produce high concentrations of carbon monoxide. While driving, air flow through the AC system ensures low CO levels inside. However, when parked with AC on and windows closed, stagnant air allows CO from the exhaust to accumulate, potentially leading to poisoning or fatalities. 2. Battery Drainage: Although the AC compressor is engine-powered, the blower fan relies on the battery. During idling, the alternator may not sufficiently recharge the battery, causing prolonged power depletion from continuous blower operation. 3. Engine Carbon Deposits: Extended AC use while idling increases fuel consumption and significantly contributes to carbon buildup within the engine components.

Is a car temperature of 90 degrees normal?

When driving normally, the optimal temperature range for a car is between 70~90℃. If the temperature exceeds 90 degrees Celsius and remains high, it indicates abnormal engine operation. A car engine requires a specific operating temperature to function properly; temperatures that are too high or too low can adversely affect the engine's normal operation and performance. Below is an introduction to car engines: Classification of engines: Based on the power source, car engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines. Principle of engines: Common gasoline and diesel engines are reciprocating piston-type internal combustion engines that convert the chemical energy of fuel into the mechanical energy of piston movement to output power. Gasoline engines have high rotational speeds, are lightweight, produce less noise, are easier to start, and have lower manufacturing costs. Diesel engines have higher compression ratios, better thermal efficiency, and superior economic and emission performance compared to gasoline engines.
