The Highlander should be filled with approximately 4.5L of engine oil, based on the dipstick's scale. Engine oil serves multiple functions such as lubrication, cleaning, cooling, sealing, wear reduction, rust prevention, and corrosion protection for the engine. Here are some additional details: 1. The engine is the heart of a car, containing many metal surfaces that move against each other. These components operate at high speeds, in harsh environments, and can reach temperatures between 400°C to 600°C. Under such severe conditions, only qualified lubricating oil can reduce wear on engine parts and extend their service life. 2. Engine oil consists of base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, providing new properties and playing a crucial role in the lubricating oil.

Which button unlocks the Roewe trunk?

The Roewe trunk switch can only be operated through two methods: the in-car button and the key remote. The in-car button is located on the inner panel of the driver's side door. If the driver is outside the vehicle, press and hold the trunk lid opening button on the remote key for more than 2 seconds to open the trunk. If the trunk lid is not closed, the trunk lid open warning light on the instrument cluster will also illuminate. Additional information: 1. The electric tailgate can only be operated when the vehicle is in P (Park) mode. The system will alert the user with a buzzer sound when the electric tailgate is opening or closing. After the tailgate opens to its preset height, it can still be manually raised or lowered. 2. If the tailgate does not open correctly to the preset height or close completely, manually closing it once can restore the electric tailgate system function. When the tailgate closes to its lowest position, it will be locked securely by the electric latch.

Can the Honda CR-V Hybrid Get a Green License Plate?

The hybrid CR-V is a non-plug-in hybrid and cannot be classified as a new energy vehicle because it essentially still relies on energy from fuel combustion. Therefore, it does not qualify for a green license plate. More relevant information is as follows: 1. In terms of appearance, the hybrid CR-V is quite conventional, with no major changes compared to the previous model. The most noticeable difference is that the rear end is no longer as raised. For the interior, soft materials are extensively used, providing a good tactile feel, and wood-grain trim panels are added in certain areas to enhance the premium feel. The dashboard features a clear LCD screen, and the center console is equipped with an 8-inch LCD display. 2. In terms of powertrain, it uses a 2.0L four-cylinder naturally aspirated engine paired with a dual-motor (one generator and one electric motor) system, along with an eCVT transmission and a lithium-ion battery pack. The engine delivers a maximum horsepower of 145 hp, while the electric motor provides 184 hp. With the support of the electric motor, acceleration and overtaking performance are both effortless.

What are the causes of transmission noise in the Envision?

The causes of transmission noise in the Envision are: 1. Issues with the transmission fluid itself, where excessive viscosity in cold conditions leads to poor fluidity during operation, causing abnormal behavior in working components. 2. Problems with the transmission itself, such as internal pressure leaks, malfunctioning valve bodies or hydraulic pistons, resulting in improper alignment of the conical wheel position. Below is a detailed introduction to the Envision's transmission: 1. The Envision's transmission is assembled and produced in mainland China; the dual-clutch transmission combines the advantages of manual and automatic transmissions, eliminating the torque converter and instead using two sets of clutches that alternate to achieve seamless gear shifting. 2. The two sets of clutches control odd and even gears respectively. Specifically, before shifting, the DSG pre-engages the next gear. Upon receiving the shift command, the DSG quickly signals the engine to increase speed, at which point the pre-engaged gear swiftly engages while the first clutch fully disengages, completing an upshift. Subsequent actions follow similarly. 3. Without a hydraulic torque converter, the engine's power can be fully utilized. Additionally, the alternating operation of the two clutches ensures extremely short shift times, minimizing power interruption from the engine.

How to reset the brake pad warning light on BMW 5 Series?

Turn on the ignition, press the reset button for 8 seconds until the oil symbol appears on the multifunction display in the instrument cluster. Press the button again to display the rear brake pad system reset. Select the item that needs to be reset, press and hold the reset button for 3 seconds until the display shows "reset", then press the reset button again until the display shows "OK". Finally, turn off the ignition. Additional information: 1. The brake pad warning system works by inserting a sensor wire into the brake pad. When the brake pad wears excessively, the sensor wire contacts the brake disc or gets worn through, causing a change in resistance that generates an electrical current. This signal is detected, triggering the brake pad warning light on the dashboard. 2. The illuminated brake pad warning light may indicate severely worn brake pads that require immediate inspection and replacement at a service center. It could also mean low brake fluid level - insufficient brake fluid reduces braking power and may even lead to complete brake failure in severe cases, requiring immediate fluid replenishment. Other possibilities include brake system leaks or false alarms, all of which need systematic troubleshooting. 3. If the brake pad warning light comes on while driving, gradually reduce speed and pull over safely. You can visually inspect whether it's a brake pad wear issue, but it's recommended to visit the nearest professional auto repair shop. Technicians can use an automotive computer diagnostic tool to check the ABS system, read fault codes, identify the problem source, and perform necessary repairs based on the diagnosis.
