What is the fuel tank capacity of the 2012 Highlander in liters?

The fuel tank capacity of the 2012 Highlander is 72 liters, as officially announced. Owners of the 2012 Highlander can also check this information on the vehicle's configuration sheet. The 2012 Highlander requires 92-octane fuel, with a fuel consumption of 9.9 to 12.1L per 100 kilometers. A full tank can cover a distance of 595 to 727 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically observed through the fuel gauge inside the vehicle. Under normal circumstances, the fuel gauge accurately reflects the fuel level. The fuel gauge usually has 5 to 6 segments, and it is recommended to refuel when only 2 segments remain to avoid running out of fuel mid-journey. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the manufacturer's specified tank capacity is measured from the bottom of the tank to a safe level, leaving some space from the safe level to the tank opening. This extra space ensures that the fuel can expand safely when temperatures rise without overflowing. If fuel is filled up to the tank opening, the actual refueling amount may exceed the marked tank capacity.

What is the difference between 91w and 94w on tires?

Tire specifications 91w and 94w refer to the tire's load index and speed rating. The number 91 indicates the load index, meaning the tire can bear a maximum weight of 615 kg, while 94 represents a load index of 670 kg. The letter 'w' denotes the speed rating, indicating the tire's maximum speed limit of 270 km/h. Here's an example to illustrate the meaning of numbers and letters in a tire model: 225/60R1799H. 1. 225: Represents the section width, which is essentially the width of the tire tread. 2. 60: Indicates the aspect ratio, referring to the height of the tire's sidewall. 3. R: Stands for the tire type code, with 'R' representing radial tires. 4. 17: Denotes the rim diameter, meaning the tire is suitable for 17-inch rims. 5. 99: Represents the load index, indicating the maximum weight the tire can bear. A load index of 99 corresponds to a maximum weight of 775 kg. 6. H: Indicates the speed rating, showing the tire's maximum speed capability. An 'H' rating means the tire can withstand speeds up to 210 km/h.

Can the All-Wheel Drive System Stay in 4WD Mode All the Time?

No, it does not remain in four-wheel drive mode all the time. The all-wheel drive system only switches to four-wheel drive when necessary, while it remains in two-wheel drive under normal conditions. The system automatically shifts between two-wheel drive and four-wheel drive modes based on the driving conditions. Related information: 1. Types: Mechanical coupling all-wheel drive, electronically controlled multi-plate clutch all-wheel drive, and intelligent electronic all-wheel drive. 2. Advantages: The all-wheel drive system has a simple structure, which effectively reduces costs and helps lower the overall vehicle weight, providing some off-road capability.

What are the contents of the C2 driver's license test?

C1 driver's license test is conducted in the order of Subject 1, Subject 2, Subject 3, and Subject 4. Only after passing the previous subject can you proceed to the next one. The specific test contents are as follows: 1. Subject 1: Road traffic safety laws, regulations, and related knowledge test. The structure and basic question types of the test question bank are formulated by the Ministry of Public Security, and the traffic management departments of provincial public security authorities establish the test question bank for their respective provinces (autonomous regions, municipalities) based on local conditions. 2. Subject 2: Field driving skills test, including: reversing into a garage, stopping and starting on a slope, turning at a right angle, driving on a curve, and parallel parking. 3. Subject 3: Road driving skills test, including basic test items: preparation before driving (walking around the vehicle counterclockwise, fastening the seat belt, light test, shifting gears, releasing the handbrake, honking the horn), starting, driving straight, changing lanes, passing through intersections, pulling over, passing through pedestrian crossings, passing through school zones, passing through bus stops, meeting vehicles, overtaking, and making a U-turn. 4. Subject 4: Safe and civilized driving common sense, test items: knowledge related to safe and civilized driving.

What Causes the Car Engine Warning Light to Come On?

Car engine warning lights are typically caused by sensor issues. Here is some relevant information about engines: 1. Introduction: An engine is a machine that can convert non-mechanical energy into mechanical energy. 2. Classification: Engines include internal combustion engines, external combustion engines, jet engines, electric motors, etc. External combustion engines convert the thermal energy generated by combustion into kinetic energy, with Watt's improved steam engine being a classic example. Internal combustion engines, specifically reciprocating piston engines, differ most significantly from external combustion engines in that their fuel burns internally. Jet engines are those that directly generate reactive thrust through high-speed airflow ejected from nozzles.

Why is a new car slow to accelerate during the break-in period?

Driving slowly during the break-in period is beneficial for the engine because the mechanical components of a new car need to wear in properly. Frequently revving the engine high and stepping hard on the accelerator during this period can cause damage to the engine. However, constantly driving at low speeds is also not advisable, as it can lead to carbon buildup in the fuel injectors, reducing the engine's effective power. Precautions for the break-in period of a new car include: 1. Warm up the car before starting: Wait 5 to 10 seconds after shifting into second gear before driving; 2. Avoid high-speed driving: There are speed limits for new cars during the break-in period, with domestic cars limited to 40 to 70 kilometers per hour and imported cars to 100 kilometers per hour; 3. Avoid overloading: Carrying too much weight during the break-in period can damage mechanical parts; 4. Do not remove the speed limiter prematurely: The speed limiter is a throttle device installed between the carburetor and the intake pipe. It should not be removed too early but rather after driving 1,000 kilometers; 5. Do not change the oil too early: The initial oil used in the car is specifically designed for the break-in period, featuring low viscosity, good heat dissipation, and excellent oxidation resistance; 6. Avoid emergency braking: Emergency braking not only shocks the braking system during the break-in period but also increases the impact load on the chassis and engine.
