Water should be added to the car radiator every two years or every 30,000 to 40,000 kilometers driven. The water referred to here is coolant, not tap water. If the coolant level in the reservoir drops below the minimum mark (the normal level should be between MIN and MAX), it should be replenished promptly. When purchasing coolant, choose the appropriate type based on the region where your vehicle is operated. Below is additional information: Notes on coolant: Coolant prevents the freezing and expansion of the cooling liquid during cold winter stops, which could crack the radiator or damage the engine block or cylinder head. It should be used year-round. It also protects engine performance, extends service life, and provides anti-freeze, anti-boil, and anti-scale functions. Especially when outdoor temperatures drop below zero, it ensures that vehicle components do not malfunction due to cold conditions.

How to Use the New Highlander 4WD?

Usage instructions for the new Highlander 4WD: 1. The all-wheel drive can be used when the vehicle is stuck in mud and needs to escape; 2. To apply strong driving force to all wheels, you can use the all-wheel drive lock mode. Press this switch, and the corresponding indicator light on the dashboard will illuminate, distributing the engine torque to the rear wheels to the maximum extent based on driving conditions; 3. Press this switch again to cancel the all-wheel drive lock mode and restore the dynamic torque control all-wheel drive system to normal mode. The front face of the new Highlander combines ruggedness with fashion. The headlights feature a new triangular design that appears sharp, and the hexagonal angular design of the front grille is very aggressive. The vehicle adopts two grille bars, an integrated Toyota bullhead logo, and thick chrome decorations. The lower air intake grille also uses a hexagonal design, with a wide chrome trim at the bottom, complemented by delicate fog lamps embedded with chrome elements, echoing the upper grille.

Does Buying a Used Car Come with Its License Plate?

Buying a used car does not include the license plate. License plates are tied to the person, not the vehicle, and cannot be transferred. To retain the original license plate, the following conditions must be met: 1. The original license plate must have been used for more than three years; 2. The application to continue using the original license plate must be submitted within six months after completing the transfer or cancellation of registration; 3. Any traffic violations or accidents involving the original vehicle must be resolved. The used car transfer process includes: 1. Signing a used car purchase agreement; 2. Checking for traffic violations—if there are any violations or if the vehicle inspection is overdue, the transfer cannot proceed; 3. Going to a used car market or any place that can issue an invoice to obtain a transfer receipt; 4. Visiting the vehicle management office or its branch at the used car market to complete the license plate registration process; 5. Staff will inspect the vehicle, take rubbings of the vehicle identification number, remove the old license plate, and take photos, for which a fee is charged.

What is a Direct Tire Pressure Monitoring System?

Direct tire pressure monitoring systems use pressure sensors installed in each tire to directly measure tire pressure. The system transmits pressure information from inside the tire to a central receiver module via wireless transmitters, then displays the pressure data for each tire. The system automatically alerts when tire pressure is too low or when there's a leak. Other tire pressure monitoring systems: Indirect tire pressure monitoring: When a tire's pressure decreases, the vehicle's weight causes that wheel's rolling radius to become smaller, making it rotate faster than other wheels. By comparing rotational speed differences between tires, the system monitors tire pressure. Indirect tire warning systems essentially rely on calculating tire rolling radius to monitor pressure. Tire Pressure Monitoring System (TPMS): This combines the advantages of both systems above, equipping direct sensors in two diagonally opposite tires while using a 4-wheel indirect system. Compared with full direct systems, this hybrid system can reduce costs while overcoming the indirect system's inability to detect simultaneous underinflation in multiple tires. However, it still cannot provide real-time actual pressure data for all four tires like direct systems can.

What type of fuel should a BMW 5 Series use?

BMW 5 Series requires fuel with an octane rating of 95 or higher. The fuel grade is classified based on the octane number, which indicates the fuel's anti-knock properties. Iso-octane has excellent anti-knock performance and is assigned an octane value of 100, while n-heptane has poor anti-knock properties and is prone to engine knocking in gasoline engines, thus assigned an octane value of 0. Higher fuel grades offer better anti-knock performance, and the appropriate fuel grade should be selected according to the engine's compression ratio. The BMW 5 Series is a mid-to-large luxury sedan under the BMW brand, with dimensions of 4998mm in length, 1901mm in width, and 1559mm in height, and a wheelbase of 3108mm. The seats and door interiors of this vehicle are adorned with premium Dakota leather, exuding an elegant and sophisticated ambiance. Additionally, it features an 8-inch screen mounted on the back of the front seats and a refrigerator compartment in the center of the rear seats.

Where is the fender located on a car?

The fender is located in the semi-circular area directly above the car tire. It not only helps reduce the drag coefficient during driving based on aerodynamics, greatly aiding the car's stability, but also prevents gravel and mud kicked up by the wheels from splashing onto the underside of the vehicle body, thereby protecting the car's chassis. The front fender is installed near the front wheels. Since the front wheels have a steering function, it is essential to ensure the maximum clearance for the front wheels when turning. Therefore, designers use wheel travel diagrams based on the selected tire model and size to verify the fender's design dimensions. The rear fender does not face issues related to wheel rotation and contact, but for aerodynamic considerations, it features a slightly arched curve that protrudes outward.
