The Highlander is equipped with an on-demand four-wheel-drive system. The central differential uses a multi-plate clutch-type limited-slip differential, along with electronic brake assistance based on the ESC system. Power is transmitted to the rear axle via an electronically controlled multi-plate clutch. The computer adjusts the power distribution between the front and rear axles based on driving conditions. Typically, the vehicle operates in front-wheel-drive mode, with automatic switching between 100:0 and 50:50 power distribution. Below is an introduction to the Highlander's four-wheel-drive system: The four-wheel-drive system is a standout feature of the Highlander. Proper use of four-wheel drive maximizes the powerful performance of this large vehicle. Additionally, the Highlander boasts HAC (Hill-start Assist Control) and DAC (Downhill Assist Control). HAC automatically maintains brake pressure on all four wheels for two seconds, effectively preventing rollback. DAC ensures the vehicle maintains a constant speed when descending steep slopes, enhancing downhill safety.

What are the symptoms of a clogged radiator?

Consequences of a clogged car radiator: The coolant cannot circulate effectively between the radiator and the engine, reducing the radiator's cooling performance. The decrease in the radiator's cooling performance causes the engine temperature to rise rapidly. If the vehicle continues to be driven under these conditions, the engine may suffer from cylinder scuffing. Below is a partial introduction to the car radiator: 1. Main components: The radiator is part of the car's cooling system. The radiator in the engine's water cooling system consists of three parts: the inlet chamber, outlet chamber, main plate, and radiator core. 2. Main function: When the engine's water temperature is high, the water pump circulates water repeatedly to lower the engine's temperature, thereby protecting the engine. In winter, if the water temperature is too low, the water circulation stops to prevent the engine temperature from becoming too low.

What to Do If Driver's License is Revoked? Do I Need to Retake the Test?

If it's over a year, you need to retake subject one and pass; if it's over three years, you need to retake all tests. 3.

How to Distinguish the Authenticity of 3M Car Film?

Methods to identify the authenticity of 3M car film include: observing the appearance of the heat-insulating film, smelling the film up close, and paying close attention to the film application effect. The specific details are as follows: 1. Observe the appearance of the heat-insulating film: Inferior films usually have a darker color to block a large amount of visible light. After exposure to sunlight, the color of the film will fade, mainly because the adhesive layer of the film volatilizes after exposure, causing color changes. More alarmingly, inferior films use ordinary, cheap materials and curing processes, which can partially melt under sunlight, causing optical distortion and posing significant driving hazards. 2. Smell the film up close: You can ask the store for scraps of the heat-insulating film and smell them up close. If you detect a strong, pungent odor, it can basically be judged as an inferior film, mainly due to the use of harmful chemical adhesive layers during the film manufacturing process.

Why can't the ETC card be detected?

The reasons why the ETC card cannot be detected are as follows: 1. Excessive speed causing unsuccessful information reading: When ETC vehicles pass through the ETC lane, the speed should be below 20 km/h. Excessive speed may prevent the lane from successfully reading the vehicle's device information. 2. The LED screen displays "No OBU" when inserting the card: In this case, you can first remove the card and reinsert it, then try entering the ETC lane again. If it still doesn't work, you can only go to the manual lane first. 3. OBU device issues: Sometimes problems like a dead battery or loose connection in the OBU can prevent the vehicle from passing smoothly through the ETC lane. In such cases, you can only go to the manual lane first and then visit an ETC service point for assistance. Vehicle owners should also properly store the ETC electronic tag, protecting it from moisture, water, and strong magnetic fields.
