Volvo XC60 is equipped with a rollover prevention system. The RSC (Roll Stability Control) system is one of the many active safety systems. Compared to ESC/ESP, it is primarily designed for high-friction road surfaces, relatively lower in cost, and easier to implement. The rollover stability system is a device that prevents vehicle rollovers. It monitors the vehicle's steering speed when turning on off-road surfaces, calculates the degree of vehicle roll based on signals from wheel sensors, and applies additional control to the outer wheels in a curve. When severe roll is detected on any side, the system quickly adjusts the braking force distribution between the wheels and reduces engine torque output to restore vehicle balance in the shortest time, minimizing the risk of rollover and ensuring the safety of occupants. The RSC system uses a gyroscopic sensor. During sharp turns or rapid steering by the driver, it automatically records the rate of change in the vehicle's tilt angle. Based on this rate, it calculates the final tilt angle to assess the risk of rollover. If a rollover risk is detected, the system activates the braking system to stabilize the vehicle, giving the driver time to handle the situation safely. The RSC system's electronic control unit includes a lateral acceleration sensor that continuously measures the vehicle's lateral acceleration and calculates the critical acceleration limit. When lateral acceleration approaches this limit, the system activates the ASR solenoid valve and the ABS solenoid valve on the drive axle to apply braking, slowing the vehicle down. For tractor-trailers, an additional solenoid valve is activated to send a braking signal to the trailer control valve, applying brakes to the trailer as well.

Where to Practice for Subject 3 Driving Test?

Subject 3 requires practicing at a driving school, as you cannot drive without a license and must learn under the guidance of an instructor using a training vehicle. Introduction to Subject 3: Subject 3 is the road driving skills test, commonly referred to as the "road test." It includes numerous test items and requires attention to many details, making it one of the more challenging parts of the driver's license examination. Key Points for Subject 3 Test: Walk around the vehicle to ensure safety before getting in. Turn on the left turn signal when starting. For the light simulation, activate the corresponding lights within 5 seconds after the voice prompt. Brake in advance at: straight intersections, bus stops, crosswalks, school zones, left/right turns, U-turns, and when meeting oncoming vehicles. After the test, remember to turn off all lights. For safety, wait until you hear "Test completed, you passed" before unfastening your seatbelt.

Can You Still Drive with a Tire Pressure of 196?

Tire pressure of 196 is not safe to drive with, and the driver should refill the tires as soon as possible. Below are the normal range of tire pressure and precautions for checking tire pressure: Normal Range of Tire Pressure: The standard tire pressure varies because different vehicles have different recommended tire pressures. Taking family cars as an example, under normal circumstances, the tire pressure should be maintained within the range of 2.2 to 2.6. Precautions for Checking Tire Pressure: As the weather starts to get hotter in May, it is recommended to check whether the tire pressure is normal. Special attention should be paid to the fact that as long as the tire pressure is not significantly higher than the standard range, there is no need to deliberately reduce the tire pressure. If the tires are not underinflated, there is no need to adjust them every month.

Do 7-seater vehicles need to go on the inspection platform every few years?

Seven-seater vehicles require platform inspections. For new vehicles within 6 years, inspections are required every 2 years. After that, inspections are required once a year for the next 15 years, and then twice a year thereafter. After 20 years, inspections are required four times a year. Vehicles registered after September 1, 2010, are exempt from inspection within the first 6 years. New regulations for seven-seater vehicle annual inspections: Non-operational small and mini passenger vehicles with 7 to 9 seats within 6 years are included in the exemption range. For non-operational small and mini passenger vehicles over 6 years but under 10 years old, the inspection frequency is adjusted from once a year to once every two years. Documents required for annual inspection: Owner's ID card; original vehicle registration certificate; valid compulsory traffic insurance policy; current year's vehicle and vessel tax payment (or exemption) certificate (the vehicle and vessel tax proof is usually included in the compulsory traffic insurance policy).

Is the white showing through a black car the primer?

Normally, if white is showing through a black car, it is the primer. Correspondingly, if black is showing through a white car, it is also the primer. It is recommended to check the vehicle's user manual, which will provide relevant information. Bumper primer: The primer for front and rear bumpers, if made of plastic, is black; if not made of plastic, there is no primer. Body and door primer: As for the body and doors, basically any color that differs from the body color is the primer. Related knowledge about car paint: The primer for plastic bumpers is different from that of the car body, as the body uses electrophoresis. Waxing can only increase the smoothness of the paint surface and provides minimal protection to the paint film, but it cannot achieve the effect of repainting.
