The reasons for the Sagitar's air conditioning not cooling are: 1. Insufficient or too little refrigerant, possibly due to minor leaks; 2. Excessive refrigerant can also cause the air conditioning to not cool; 3. The drive belt of the car's air conditioning compressor is loose. Car cooling relies on refrigerant, and refrigerant transmission depends on the air conditioning compressor. The drive belt is an important moving part that drives the air conditioning compressor; 4. Unqualified refrigerant and excessive impurities in the refrigerant and freezer oil can also cause the car's air conditioning filter to clog, leading to the air conditioning not cooling, increased resistance, and reduced refrigerant flow to the expansion valve, resulting in insufficient cooling capacity; 5. Water ingress into the refrigeration system can cause insufficient cooling or no cooling at all. In terms of power, the 2012 Sagitar 1.6L model is equipped with an EA111 series engine, with a maximum output power increased to 105 horsepower and a peak torque of 155Nm, paired with a 5-speed manual or 6-speed automatic transmission. The Sagitar's body dimensions are 4655mm, 1780mm, and 1453mm.

Last time my Sagitar's air conditioning wasn't cooling, and after inspection, it was found that the refrigerant was leaking. Aging pipelines might have cracks, and when the refrigerant level drops, cold air stops coming out. Compressor failure can also affect it, such as when the electromagnetic clutch doesn't engage, causing the system to shut down directly. The fan not spinning or a blown power fuse, leading to poor heat dissipation, is also a common cause. A clogged condenser or a dirty filter can reduce airflow, making it feel less cool. You can first listen for a clicking sound when the compressor starts and check if the fan under the hood is running when the AC is on. Address these issues early to avoid sweating profusely while driving in summer, and remember to regularly maintain and clean the air conditioning system.

What is the wading depth of the Wuling Hongguang?

The maximum wading depth of the Wuling Hongguang is 300mm. The wading depth of the Wuling Hongguang is determined by the height of the vehicle chassis, which is the ground clearance listed in the model's parameter configuration table. Generally speaking, the greater the ground clearance, the higher the chassis, and the higher the safety factor when passing through waterlogged roads. Therefore, in terms of safe wading depth, the advantages of off-road vehicles and SUVs are obvious. 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 Wuling Hongguang is lower than the water level during wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it will cause serious damage to the engine's mechanical structure (connecting rods, pistons, crankshaft, etc.). Therefore, the wading depth should not exceed the height of the engine's air intake. The height of the engine's air intake, and thus the maximum wading depth, can also be increased by installing a snorkel. If wading is unavoidable, the following safe and correct operations should be performed: Before the vehicle enters the water, the auto start-stop function must be turned off to prevent the vehicle from automatically restarting after stalling in the water, which could cause serious damage to the engine due to water intake; Based on the passage of the vehicle ahead, judge the underwater road conditions and choose a suitable entry point. Observe the path taken by other vehicles and follow their tracks at low speed, avoiding sudden acceleration or deceleration; On roads prone to water accumulation, observe warning water level markers, trees, and other reference points such as the wheels and doors of other vehicles to determine the water depth before deciding whether to proceed; Understand your vehicle's safe wading depth. If the water depth exceeds half the height of the tires or the engine's air intake, do not enter the water recklessly; choose another route instead.

Can the Wuling Hongguang mini be charged outdoors on rainy days?

The Wuling Hongguang mini can be charged outdoors on rainy days, but it is not recommended to charge in the rain. The main circuits of electric vehicles are protected by casings, and the charging gun is waterproof, meaning there is no need to worry about rain, splashing water, or humid weather in the south. It won't be easily damaged by getting wet. When charging an electric vehicle in the rain, pay special attention to the following points: When parking, try to choose a higher ground position. If parked in a low-lying area, prolonged water accumulation may cause the battery or charging port to be submerged in water. Check the charging gun to ensure there is no accumulated water or debris inside, and that the charging gun and charging port can make full contact for normal charging. Do not wait until the battery is completely depleted before charging. Fully depleting the battery can easily cause damage, which is permanent for new energy vehicles. Avoid charging when the temperature is too low, as it can also damage the battery. It is recommended to start the car and warm it up for about 10~20 minutes before charging. After charging is completed, when removing the charging gun from the vehicle, promptly cover the charging port to ensure it is tightly sealed and no water can enter. It is advisable to use an umbrella during the entire process from unplugging the charging gun to charging, and keep the charging gun facing downward to minimize rainwater entering the charging components. The Wuling Hongguang MINI was designed with a leakage protection function from the start. If rainwater seeps in during charging and there is a risk of leakage, the leakage protection switch will automatically cut off the circuit to ensure safety. In summary, charging the car on a normal rainy day is not a problem, but be sure to prevent rainwater from entering the charging components and interfaces throughout the process. Avoid charging during heavy rainstorms, as safety should always come first.

Can You Speed Up When the Yellow Light Flashes at an Intersection?

You cannot speed up when the yellow light flashes at an intersection. A flashing yellow light indicates that the signal is about to turn red. Vehicles that have already crossed the stop line may accelerate to pass through, while vehicles that have not crossed the stop line must stop and wait. If the yellow light flashes continuously, it means drivers should slow down, pay attention to oncoming traffic from both sides, and be prepared to yield. Therefore, accelerating is not allowed. According to the new "Road Traffic Safety Law," when the yellow light flashes at an intersection, vehicles that have already crossed the stop line may continue to pass, while vehicles that have not crossed the stop line must stop. Driving through a yellow light is considered running a red light. If a vehicle continues to rush through after the yellow light turns on, it will be recorded as running a red light by traffic cameras. If a vehicle has just crossed the stop line when the light turns red but stops immediately, traffic authorities will not impose penalties. However, if the vehicle moves significantly after crossing the line, it will be penalized. If a vehicle passes through a yellow light due to being blocked by the vehicle in front, it does not count as running a red light. In such cases, the driver can appeal to the local traffic police department to revoke the penalty. Having evidence like dashcam footage increases the chances of successfully overturning the penalty through administrative reconsideration. To avoid crossing the intersection during the transition from yellow to red, drivers should stop when the green light is about to turn off. The yellow light lasts for 3 seconds, and if a vehicle cannot pass within this time, it will turn red. Whether running a red or yellow light, fines will be imposed.

Which Gear is the Forward Gear?

For automatic transmission vehicles, the D gear, S gear, and L gear can all move the car forward. Among these, the most commonly used gear is the D gear. For manual transmission models, forward gears are represented by numbers. Below is an introduction to the forward gears in automatic transmission vehicles: 1. D gear: The D gear, short for 'drive,' is the most frequently used gear for forward movement. Engaging the D gear and pressing the accelerator will move the car forward. 2. S gear: The S gear, short for 'sport,' is the sports mode. As the name suggests, this gear enhances the vehicle's power output. When shifted into S gear, the car will upshift later or downshift earlier, keeping the engine at higher RPMs to increase torque output for greater power. The S gear is typically used for overtaking and can sometimes be useful in traffic jams. However, using the S gear increases fuel consumption. 3. L gear: The L gear, short for 'low,' is the low-speed gear, also known as the climbing gear. Its function is to reduce speed and increase torque, commonly used when climbing hills, equivalent to the 1st gear in a manual transmission. The L gear is also used when descending hills. If the D gear is used instead, the driver would need to rely on the brakes to control speed, which, if used frequently over time, can lead to overheating and reduced braking efficiency, as well as significantly shortening the lifespan of the brake pads. Engaging the L gear forces the transmission to maintain low RPMs, using engine braking to control speed with supplementary use of the brakes.
