Why is Lexus called the Highway Lightning?

What are the precautions for reversing a car?

When reversing, pay attention to the surroundings, the interior environment of the car, and the front of the car. Also, remind pedestrians to yield and brake in time if necessary. Observe the surroundings: Before reversing, check the situation behind the car, and get out to inspect if necessary. This can prevent unseen objects in blind spots and help plan the reversing path. While reversing, observe obstacles on both sides and continuously monitor the road conditions in the rearview mirrors. Observe the interior environment: Remove items inside the car that may obstruct the view; it's best to temporarily turn off audio equipment to hear external sounds promptly; open the windows to check the rearview mirrors during reversing. Pay attention to the front: If the front of the car is neglected while reversing, the sides of the front may get scratched. When reversing to the left, pay attention to the right front, and when reversing to the right, pay attention to the left front. Remind pedestrians to yield: In crowded areas, honk in advance to alert pedestrians to yield. Always be ready to brake: While reversing, if the rearview mirrors or radar indicate danger, brake immediately and get out to inspect if necessary.

What Causes the Abnormal Noise When Turning the Steering Wheel While Reversing?

The causes of abnormal noise when turning the steering wheel while reversing include friction between plastic components, friction between the steering column and the floor mat, failure of the clock spring inside the steering wheel, and aging of the steering tie rod ball joint. Friction between plastic components: The steering wheel is composed of various plastic parts. If the gaps between these parts are too small, friction will occur when the steering wheel is turned. For a new car, the steering wheel will adapt after some time of use. If the noise persists after this period, try reassembling the steering wheel. Friction between the steering column and the floor mat: If the aftermarket floor mat is too large and directly contacts the steering column, friction will occur as the steering column turns. Adjusting the position of the floor mat or replacing it can resolve the issue. Failure of the clock spring inside the steering wheel: If the clock spring is broken or its connector is not properly plugged in, replacing or securing it will fix the problem. Aging of the steering tie rod ball joint: Replacing the steering tie rod ball joint will solve the issue, but a four-wheel alignment is required after replacement.

What Causes Sudden Abnormal Noises When Reversing?

There are several reasons why a car may suddenly produce abnormal noises when reversing, including wheel damage, shock absorber failure, transmission malfunction, and brake pad issues. Car Tire Damage: If a car tire has bulges or is punctured by foreign objects such as nails, it can cause abnormal noises when reversing or moving forward. In such cases, simply repairing or replacing the tire will resolve the issue. Car Shock Absorber Failure: When a car's shock absorber fails, abnormal noises may also occur when turning or driving over bumpy roads. This situation requires replacing the shock absorber at a repair shop or 4S store. Car Transmission Malfunction: If the car's transmission malfunctions, such as damage to the reverse gear, friction can cause abnormal noises. In this case, the transmission needs to be opened for inspection and replacement of the gears. Car Brake Pad Issues: Brake pad failure is a common cause of abnormal vehicle noises. Brake pad problems include improper installation, severe wear, or foreign objects trapped between the brake pad and caliper. The specific situation requires removing the car tire to inspect the brake pads before performing repairs, and in some cases, directly replacing the brake pads.

Does Launch Control Damage the Car?

Launch control is very damaging to the car. It is an operation that puts stress on both the engine and transmission, affecting every moving component from the engine to the tires. Therefore, launch control is highly detrimental to the vehicle. Frequent use of launch control can directly lead to transmission failure. Hence, it is crucial to exercise caution when employing launch control. Most automatic transmission vehicles simulate launch control through programming, while manual transmission cars rely entirely on the driver's operation to execute a launch. During launch control, the engine is pre-revved to a certain RPM. For automatic transmission vehicles, the driver needs to simultaneously press the brake pedal and the accelerator pedal, then release the brake pedal once the launch control mode is activated. For manual transmission cars, the driver must press both the clutch pedal and the accelerator pedal while engaging first gear. Once the engine reaches the desired RPM, the clutch pedal should be quickly released.

What Causes the Reversing Radar to Stop Speaking?

Reversing radar stops speaking due to reasons such as the radar switch being turned off, wiring faults, or malfunctions in the radar itself. Radar Switch Turned Off: Most vehicles have a control switch for the reversing radar on the central control panel inside the car. If it is turned off, the reversing radar will not function. The solution is to turn on the reversing radar switch. Reversing Radar Wiring Fault: When the reversing radar wiring ages or breaks, the radar will fail to operate normally. Timely repair or replacement of the wiring harness is required. Radar Itself Malfunctioning: If the reversing radar is found not to beep, first check whether the power cable of the main unit is properly connected and if there is current. Then inspect whether the radar main unit wires have become loose. If both aspects are fine, the issue lies with the radar itself. The radar's buzzer may be damaged, in which case purchasing and installing a new buzzer will suffice. Alternatively, the reversing radar control unit itself may be damaged, leading to the entire reversing radar system malfunctioning. A power reset can be attempted first. If the issue persists after resetting, it is likely that the control unit itself is damaged, necessitating replacement or repair of the reversing control unit.

What is the matching range between gears and vehicle speed?

1st gear is used for normal starting or climbing very steep slopes, with a speed generally around 10 km/h; 2nd gear is a transitional gear for acceleration after starting or for low-speed driving, with a speed generally around 20 km/h; 3rd gear is used at speeds between 20-40 km/h, commonly used for urban driving; 4th gear is used at speeds between 40-60 km/h; 5th gear can be used at speeds of 60 km/h or above. When driving a manual transmission, the gear shifting sequence must be from 1st to 2nd to 3rd to 4th to 5th gear, and skipping gears is not recommended. The downshifting sequence should be determined based on the condition of your vehicle, generally downshifting when the engine speed drops below around 1500 RPM. The larger the gear, the slower the rotation speed, corresponding to a lower gear and slower vehicle speed; the smaller the gear, the faster the rotation speed, corresponding to a higher gear and faster vehicle speed. If the gear does not match the engine speed, a mismatch between engine power and transmission gears will occur, leading to the phenomenon of the vehicle jerking forward and backward.
