Turning on the AC in an SUV increases fuel consumption by approximately 20%. The specific impact depends on the vehicle's displacement and speed. For instance, a car that normally consumes 10 liters per 100 kilometers will see an increase of about 2 liters when the AC is on. To check the remaining fuel in the tank, drivers can observe the fuel gauge on the right side of the dashboard, marked with E and F. When the needle is close to E, it indicates low fuel, while proximity to F means the tank is nearly full. Maintenance tips for the fuel tank include: Draining accumulated water and sediment from the tank, and inspecting fuel line connections and switches for any leaks. For fuel tank caps equipped with air and vapor valves, ensure the vent holes are clear. The filter screen at the fuel filler neck should remain intact to prevent contaminants from entering the tank and clogging the fuel lines during refueling. The sealing gasket on the fuel filler cap should also be in good condition to prevent fuel spillage while driving.

What does the AVH Auto Hold System mean?

The AVH Auto Hold System is an automatic braking function. After activating this function, for example, when stopping at a traffic light, it eliminates the need to pull the handbrake, simplifying operations by avoiding the use of manual or electronic handbrakes. For automatic transmission models, it also reduces the need for frequent shifting between D to N or D to P. The functions of the Auto Hold System include: Preventing rolling: When briefly stopping at a traffic light, the system automatically brakes the wheels after the vehicle comes to a complete stop to prevent rolling; Preventing backward sliding: When starting on an uphill slope, the system automatically brakes to prevent backward sliding, and releases the wheels to move forward once the vehicle starts; Automatic braking: Some models automatically brake the wheels when parking and locking the vehicle, eliminating the need to pull the handbrake. How the Auto Hold System works: When the vehicle is temporarily stopped and needs to restart within a short period, the parking is handled by the ESP-controlled braking system. The computer uses a series of sensors to measure the vehicle's levelness and wheel torque, determining any tendency for the vehicle to roll and applying an appropriate braking force to keep the vehicle stationary. This braking force is just enough to prevent movement without being too strong, ensuring a smooth start when the accelerator is pressed again. If the temporary stop exceeds a certain duration, the braking system switches to mechanical rear-wheel parking (activating the electronic handbrake) instead of the previous four-wheel hydraulic braking. When the vehicle is ready to move forward, the electronic system detects the accelerator pedal pressure and, for manual transmission models, the clutch pedal travel to determine whether to release the brake.

Is Car Window Tinting Applied on the Inside or Outside?

Car window tinting should be applied on the inside of the car glass. Here are the reasons for applying it on the inside: 1. Tinting on the inside is not exposed to wind and rain, slowing down the aging process and thus extending its lifespan. 2. The film is less susceptible to external interference when applied inside, preventing scratches and damage. Without exposure to weather, the adhesive remains stronger, avoiding peeling or lifting at the edges. There are seven major benefits of car window tinting: 1. Heat and Sun Protection: The film effectively blocks infrared rays, reducing heat buildup. 2. UV Protection: Medium and long-wave ultraviolet rays can penetrate thick glass, but tinting can block most UV rays, protecting the skin and reducing interior aging. 3. Safety and Shatterproof: The film's base layer is made of polyester, providing tear and puncture resistance. Combined with the adhesive layer, it strengthens the glass, preventing injuries from accidental shattering. 4. Privacy Enhancement: With the right type of film, the interior becomes less visible from the outside while maintaining clear visibility from the inside, ensuring privacy and safety. 5. Reduced Air Conditioning Load: Tinting compensates for AC cooling loss, quickly lowering the interior temperature and improving fuel efficiency. 6. Aesthetic Appeal: Customize your car's appearance according to personal preference. 7. Anti-Glare: Reduces accidents caused by glare.
