What does brake-hold mean in a car?

1 Answers

brake-hold refers to ABH (Auto-Brake-Hold), the automatic parking system. When the function is activated, the vehicle can be stopped by pressing the brake pedal during temporary stops. To resume driving, simply press the accelerator pedal to release the braking force. This allows the driver to avoid prolonged braking when the vehicle is stationary and prevents unnecessary rolling when the automatic electronic parking brake is engaged. Additional Information: 1. Meaning of the Automatic Parking System: The automatic parking system (Auto-Brake-Hold) is a technology that enables the automatic application of the parking brake while the vehicle is in operation. This technology allows the driver to avoid prolonged braking when the vehicle is stationary and prevents unnecessary rolling when the automatic electronic parking brake is engaged. The function of the automatic parking system is to prevent the vehicle from rolling backward, making it particularly useful on slopes and during frequent stops and starts. 2. Function of the Automatic Parking System: The automatic parking system, together with the electronic parking brake (EPB: Electrical-Park-Brake, technical name: electromechanical parking brake), forms an intelligent braking control system. This system integrates temporary braking during driving and long-term braking after parking, and the parking brake is controlled electronically.

Why Are Cars Recalled?

There are several reasons why cars are recalled: Automobile manufacturers discover certain issues with a particular model, necessitating a recall. Below is relevant information about car recalls: 1. Process: The car recall process involves the manufacturer effectively notifying relevant parties such as dealers, repair shops, and car owners about the specifics of the defect and the methods to rectify it. The manufacturer then organizes dealers and repair shops to eliminate the defect through measures such as repairs, replacements, or returns. 2. Recall Materials: These mainly include: recall plan filing application, recall plan, recall announcement, recall press release, recall notice, recall repair procedures, recall cost statistics, recall progress reports, and recall summary report. 3. Nature: The purpose of a car recall is to eliminate potential safety hazards posed by defective vehicles to society and to safeguard public safety.

What kind of engine oil does the Buick Envision use?

Buick Envision uses fully synthetic engine oil with a viscosity grade of 5W30. Engine oil, motor oil, or engine lubricant is a substance composed of base oils enhanced with additives, primarily containing anti-wear agents, detergents, dispersants, and multi-grade viscosity index improvers. Engine oil is used for lubricating internal combustion engines. The Buick Envision is a model under SAIC-GM, with body dimensions of 4686mm in length, 1839mm in width, and 1660mm in height, and a wheelbase of 2750mm. In terms of exterior features, the Envision is equipped with an intelligent air intake grille for reduced drag, aluminum roof rails, chrome dual exhaust pipes, 19-inch multi-spoke aluminum alloy wheels, and multi-function exterior mirrors. For the interior, the Envision continues Buick's luxury concept, featuring front-row multi-function seats, adjustable and sliding rear seats with reclining backrests, a large split central storage box, and a heated steering wheel.

Why is it difficult to capture illegal U-turns?

Illegal U-turns may be difficult to capture when they occur in the absence of no U-turn signs or dedicated U-turn traffic signals. Scenarios where U-turns are prohibited: Intersections marked with no U-turn signs; if the road centerline is a solid line, whether it's a single yellow line or double yellow lines, U-turns are prohibited; no-left-turn intersections prohibit U-turns; U-turns are forbidden at pedestrian crossings along road sections. Precautions for U-turns: U-turns are prohibited at pedestrian crossings. Although pedestrian crossings in road sections with traffic separation barriers may not have no U-turn traffic signs, pedestrians have the right of way, and pedestrian crossings are treated as prohibitive signs. Any U-turn at a pedestrian crossing will be penalized as an illegal U-turn at a prohibited location.

What to Do If You Accidentally Fill 95 Gasoline with 92?

If you accidentally fill 95 gasoline with 92, it's generally not a problem to mix them occasionally. Mixing different grades and types of gasoline won't cause noticeable issues in the short term. Problems like carbon deposits and fuel line blockages are caused by long-term mixing. After mixing different grades of gasoline, no special maintenance is required. Simply refill with the appropriate grade of gasoline as specified by your vehicle when conditions permit. The octane levels of 95 and 92 gasoline are different, with varying amounts of anti-knock agents added. 95 gasoline has a slightly higher proportion of anti-knock agents compared to 92. The quality of both types of gasoline is exactly the same, and there is no difference in cleanliness. The only difference lies in the amount of anti-knock agents added, which is designed to meet the different anti-knock requirements of engines with varying compression ratios.

What is the normal engine idle speed for a car?

Generally, the normal idle speed for a sedan ranges from 700 to 900 RPM. Below is relevant information about car idle speed: 1. Definition: Idle speed refers to the engine operating without any load, only overcoming internal friction resistance without delivering power output. The minimum stable engine speed under these conditions is called idle speed. The idle speed can be adjusted by modifying the throttle opening size, with the optimal idle speed being the lowest RPM at which the engine doesn't vibrate. 2. Idle performance: Car engine idling is one of the engine operating conditions. The idle performance significantly impacts emissions, fuel consumption, and driving comfort. The engine speed during idling is called idle speed, which shouldn't be too high or too low - excessively high idle speed increases fuel consumption, while excessively low speed causes unstable engine operation.

What does it mean when a wrench light comes on in a car?

A wrench light coming on in a car is a reminder to the owner that maintenance is due. The wrench indicator on the dashboard is a maintenance reminder light. This light functions like a timer, alerting the owner when it's time for maintenance, and does not indicate a fault. Typically, after maintenance is completed, the service staff will reset the maintenance light. If the light remains on after maintenance, you can also reset it yourself. Many modern vehicles allow this to be done via buttons on the multifunction steering wheel by selecting the appropriate menu option to enter the maintenance interface on the dashboard and resetting it. The method to reset the maintenance light varies by vehicle brand and model, and the standard procedure can be found in the user manual. Regular vehicle maintenance includes eight key items: engine oil, oil filter, transmission fluid, spark plugs, cabin air filter, engine air filter, fuel filter, and brake fluid.
