What is the recommended tire pressure for the Envision?

1 Answers

07/30/25 1:00am
The normal tire pressure range for the Buick Envision is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and decreased by 0.1 bar in summer. This data complies with the international GBT2978-2008 standard. The Buick Envision is equipped with an active tire pressure monitoring system, allowing drivers to view specific tire pressure values directly on the instrument panel. The tire pressure monitoring system automatically monitors tire pressure in real-time while driving and alerts the driver to leaks or low pressure to ensure driving safety. Generally, a tire pressure exceeding 2.8 bar is considered too high, while a pressure below 2.0 bar is too low. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, lowering driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting other components' longevity; overstretches tire cords, reducing elasticity and increasing load during driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; makes steering heavy and prone to deviation, compromising safety; excessive movement of tire parts causes abnormal heat generation; weakens cord and rubber functionality, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies friction with the ground, rapidly raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in a blowout. If the tire pressure monitoring indicator lights up (a yellow symbol with an irregular circle, no seal on top, four small spikes below, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure. The system typically alerts when pressure is below 1.8 bar or above 3.0 bar. In this case, inspect the tires and adjust the pressure. Tire pressure monitoring not reset. After inflating the tires, failing to reset the tire pressure monitoring system means it still records the previous data, causing the indicator to light up. Simply reset the system. Damaged tire pressure sensor. The sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If damaged during driving, it triggers the tire pressure warning light. A damaged sensor must be replaced. For the Envision, a tire pressure between 2.3-2.5 bar is generally normal. A full load may require around 2.5 bar, while two passengers may find 2.3 bar sufficient. Hazards of abnormal tire pressure include: 1. Overinflation: Overstretches tire cords, causing the central tread to bulge and wear excessively; reduces contact area with the ground, lowering adhesion and increasing skidding risk and braking distance; decreases tire elasticity, making the ride harsher and reducing comfort; increases tension on the cord layers, lowering puncture resistance and raising blowout risks on rough roads. 2. Underinflation: Causes the central tread to lift off the ground, wearing the shoulder areas excessively; increases rolling resistance and fuel consumption; softens the tire, leading to excessive heat generation during high-speed driving, accelerating aging and blowout risks.

How to Maintain a New Car Battery?

The maintenance methods for a new car battery are as follows: 1. The car should not be left idle for long periods. A car that is not used for an extended time will gradually lose battery charge, which may lead to difficulty starting the car when needed. If the car is used infrequently, it is advisable to drive it periodically to keep the battery fully charged. 2. Avoid using electrical devices after turning off the engine. For example, listening to music while the engine is off consumes the battery's power. Prolonged use can drain the battery completely, resulting in failure to start the car. It is recommended that owners refrain from using electrical devices after turning off the engine. 3. Clean and maintain the battery. Regularly clean the car battery by wiping the positive and negative terminals with a dry cloth to remove dust, grease, white powder, and other contaminants that may cause leakage. Avoid using a wet cloth to prevent electric shock. If owners find it difficult to perform these tasks, it is recommended to visit a 4S store or a professional repair facility for assistance.

Can a car pass the annual inspection after installing fog lights?

Installing fog lights on a vehicle does not affect the annual inspection, and it can pass. The prerequisite is that the vehicle has applied for record filing at the local vehicle management office before the modification, and the fog lights are installed by professional modifiers, with the color of the added fog lights consistent with that of standard fog lights. The external structure, brightness, and angle of illumination of the added fog lights must match those of standard vehicle fog lights. If the color of the fog lights installed by the owner does not comply with regulations, the appearance differs from standard vehicle fog lights, or the angle of illumination is too high, the vehicle will not pass the annual inspection due to these issues. Fog lights are installed at the front and rear of the car, divided into front fog lights and rear fog lights. Front fog lights are white or yellow, while rear fog lights are red. Since light can increase visibility distance, especially yellow anti-fog lights, which have strong light penetration, they can improve the visibility of the driver and surrounding traffic participants in low-visibility foggy conditions where the driver's line of sight is limited. This allows oncoming vehicles and pedestrians to spot each other from a greater distance. Therefore, installing fog lights on low-end cars is legal and beneficial for safety. As fog lights are considered safety devices, the Ministry of Public Security requires motor vehicles to install fog lights that comply with national standards. Motor vehicles without rear fog lights installed as required are not allowed to enter highways. When installing vehicle fog lights, wiring needs to be rerouted at the vehicle's battery. Therefore, it is necessary to have professionals install the fog lights to prevent improper wiring from affecting the normal use of other vehicle circuits.

What are the vision requirements for a driver's license medical examination?

The vision requirements for a driver's license medical examination are as follows: 1. For applicants applying for large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, large trucks, trolleybuses, or tramcars, the naked or corrected vision of both eyes must reach 5.0 or above on the logarithmic visual acuity chart. 2. For applicants applying for other types of driving licenses, the naked or corrected vision of both eyes must reach 4.9 or above on the logarithmic visual acuity chart. 3. No red-green color blindness. The actual content of the driving school medical examination is consistent with the vision requirements. In the vision requirements for a driver's license medical examination, generally, those without vision impairment or red-green color blindness can pass normally. If the eyes have myopia or astigmatism, the vision can also be tested after correction. Myopia is usually corrected by wearing myopia glasses or through surgery. As long as the corrected vision meets the medical examination's vision requirements, the applicant can pass the driver's license vision examination. Other items of the driving school medical examination stipulated in Article 11 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses": Height: Applicants for large passenger vehicles, tractors, city buses, large trucks, or trolleybuses must be at least 155 cm tall. Applicants for medium-sized passenger vehicles must be at least 150 cm tall. This is the first step of the driving school medical examination. Hearing: Both ears must be able to distinguish the direction of the sound source at a distance of 50 cm from the tuning fork. Upper limbs: Both thumbs must be sound, and each hand must have at least three other sound fingers, with normal limb and finger movement functions. Lower limbs: Normal movement function. For applicants applying to drive manual transmission vehicles, the length difference of the lower limbs must not exceed 5 cm. For applicants applying to drive automatic transmission vehicles, the right lower limb must be sound. Trunk and neck: No movement dysfunction. The "Physical Condition Certificate" submitted by the applicant must be issued by a medical institution at or above the county level or the regimental level of the military. County-level or above medical institutions refer to: municipal hospitals and disease prevention and control centers confirmed by the Health Bureau; district and county central hospitals.

What causes the steering wheel to pull to one side?

Steering wheel pulling to one side may be caused by the following situations: 1. Uneven cushioning due to deformation of front shock absorber springs on both sides. The condition of the shock absorber springs can be judged by pressing or comparing after disassembly. 2. Failure of the front shock absorber. After the front shock absorber fails, the vehicle's suspension will be uneven during driving, causing uneven force distribution and resulting in pulling. The absorption of the shock absorber can be tested with a specialized testing device to determine its condition. If no equipment is available, disassembly and stretching can be used for judgment. 3. Unequal tire pressure is a major cause of vehicle pulling. The position of the tires should be rotated every 20,000 kilometers, as the wear on the drive wheels is always greater than on other wheels, and different friction can directly cause pulling. 4. Poor return or incomplete separation of a wheel's brake. This is equivalent to applying partial braking on one side, which will inevitably cause the vehicle to pull. During inspection, the temperature of the wheel hub can be checked. If one wheel is significantly hotter than others, it indicates poor brake return. 5. The condition of the steering system also affects the vehicle's straight-line driving. Excessive wear gaps in connecting parts or looseness caused by wear in bearings, kingpins, or bushings will cause the vehicle to sway during driving and fail to maintain a normal trajectory. If the steering knuckle arm or steering knuckle is bent or deformed, it usually causes the vehicle to pull to one side. The most severe case is severe wear and detachment of the tie rod ball joint, which will lead to steering failure and complete loss of vehicle control.
