What is the fuel consumption of the GLK300?

How long can a vehicle be parked without turning off the engine?

Vehicles can be parked without turning off the engine until the fuel is exhausted, with the specific duration depending on the fuel level. Here are relevant details: 1. Idling: Idling refers to the operation of the engine without any load, where it only needs to overcome the internal friction resistance of its components and does not output power externally. The minimum speed required to maintain stable engine operation is called idling speed, which is one of the five basic operating conditions of an engine. 2. Gasoline: Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained through the distillation and cracking of petroleum, used as fuel. It appears as a transparent liquid, is flammable, with a distillation range of 30°C to 220°C, and mainly consists of C5 to C12 aliphatic hydrocarbons and cycloalkanes.

Are all questions in Subject 4 multiple-choice?

Exam questions include image-based questions, scenario identification questions, and text-based questions. Below is an introduction to the Subject 4 exam: 1. Scope: Depending on the type of driver's license being tested, 50 questions are randomly selected from the corresponding Subject 4 question bank in proportion. For small vehicle licenses, questions are selected from a pool of 1235 questions, while for large vehicle licenses, questions are also selected from a pool of 1235 questions, with each question worth 2 points. 2. Time: The exam duration is 45 minutes. If 12 points (6 questions) are answered incorrectly during the exam, the session will be terminated. 3. Question types: The exam includes true/false questions (questions 1--22), single-choice questions (questions 23--45), and multiple-choice questions (questions 46--50).

What to Do When Car Coolant Is Insufficient?

When the car coolant is insufficient, it should be appropriately replenished. Insufficient coolant cannot effectively cool the engine, which may accelerate engine wear in mild cases and potentially lead to engine burnout in severe cases. Below is a partial introduction to coolants: 1. Alcohol-based coolant: Uses ethanol (commonly known as alcohol) as an antifreeze. It is inexpensive, has good fluidity, and is simple to prepare, but it has a low boiling point, is prone to evaporation, has an easily elevated freezing point, and is flammable. It is gradually being phased out. 2. Glycerin-based coolant: Has a high boiling point, low volatility, is non-flammable, non-toxic, and has low corrosiveness, but it is less effective at lowering the freezing point and is costly. Only a few Nordic countries still use it.

What are the main violations captured at traffic enforcement cameras?

Violations captured by traffic cameras include: running red lights, not driving in designated lanes, driving in the wrong direction, violating prohibitive road markings, making U-turns or left turns where prohibited, drivers not wearing seat belts as required, vehicles illegally using dedicated lanes, and large trucks entering restricted zones. Driving tips: 1. Slow down when approaching signalized intersections, maintain a safe braking distance, and avoid speeding up when the yellow light flashes. 2. Choose the correct lane. When approaching a signal-controlled intersection with designated lanes, enter the appropriate lane based on your intended direction. Do not go straight in a turning lane or turn in a straight lane. 3. Plan your route wisely. Before entering an intersection, observe the directional signs and lane markings to plan your route properly, and avoid crossing single or double solid lines at intersections.

What causes pressure loss in the right rear tire?

Right rear tire pressure is abnormal and requires calibration. Here is relevant information: Tire Pressure: Tire pressure monitoring can include two types, direct and indirect. Direct systems are more expensive but provide more accurate monitoring results. Direct tire pressure monitoring uses sensors installed inside the tires to measure tire pressure, then transmits the information to the dashboard via a wireless transmitter. When the tire pressure is too low or too high, it automatically alerts and displays the pressure value. Direct tire pressure monitoring is more expensive but more precise. Tires: Car tires are one of the most important components of a vehicle, directly contacting the road surface and working with the suspension system to absorb shocks during driving, ensuring good ride comfort and smoothness. They also maintain strong traction between the wheels and the road, improving the vehicle's traction, braking, and off-road capability. Additionally, they bear the weight of the car, making their role increasingly recognized as crucial.
