What does Honda Cruise mean?

Honda CRUISE indicates that the cruise control is currently active, allowing the driver to maintain a fixed speed without pressing the accelerator pedal. To activate Honda's cruise control, press the cruise control switch on the steering wheel, and the cruise control system indicator will appear on the instrument cluster. Press the accelerator pedal until the vehicle reaches the desired speed (30 km/h). Press the "SET" side of the "RES/SET (Resume/Set)" switch on the steering wheel and release it, then you can release the accelerator pedal. To temporarily deactivate the system, press the brake pedal or move the cruise control switch to the "OFF" position. To resume the set cruising speed, release the brake or clutch pedal and press the resume function button again. The cruise control system is not suitable for all situations. In principle, cruise control should be used on highways or fully enclosed roads, as complex road conditions on non-enclosed roads can compromise traffic safety. When using the cruise control system, always set an appropriate speed based on road limits, traffic flow, road conditions, and other factors. Avoid using cruise control when driving on slopes, slippery roads, or winding roads to prevent safety incidents.

How to Adjust Tire Wear?

Tire wear adjustment methods are as follows: 1. Adjust tire pressure. Both overinflation and underinflation can cause uneven tire wear. When tire pressure is too low, the tire bends inward, which can lead to severe wear on the tire edges. When tire pressure is too high, the central tread of the tire will experience accelerated wear. Therefore, it's important to regularly check whether the tire pressure is at a normal level. Generally, inflating or deflating according to the vehicle's specified tire pressure is sufficient. 2. Perform wheel balancing regularly. Due to manufacturing processes or certain external factors, the mass distribution of wheel components may become uneven. When car wheels rotate at high speeds, this can create dynamic imbalance. To prevent or correct this condition, counterweights are added during dynamic conditions to balance the wheel edges, thereby avoiding uneven tire wear. 3. Perform wheel alignment regularly. Wheel alignment enhances driving safety, extends tire lifespan, reduces fuel consumption, minimizes tire wear, and decreases suspension component wear. Therefore, it's essential to schedule regular wheel alignment at 4S shops or professional repair facilities.

Is There Compensation for Quality Issues in New Cars After Repair?

After repairing quality issues in a new car, you can request compensation from the 4S store. Legal Provisions: The new automobile three-guarantee regulations stipulate that if the vehicle has issues with major (important) components such as the transmission or engine due to inherent defects, and after diagnosis by the dealership and manufacturer, the product cannot meet functional and usage requirements, the consumer is entitled to request repair, return, or compensation. New Automobile Three-Guarantee Rules: If a newly purchased car is found to have quality issues, consumers can request replacement or return from the seller by presenting the three-guarantee certificate and purchase invoice. During the warranty period, if there are product quality issues with a family car, consumers can receive free repairs from the repairer by presenting the three-guarantee certificate, including labor and material costs.

What is the purpose of cruise control?

Cruise control automatically maintains the vehicle's speed at the driver's desired setting after activation, eliminating the need to press the accelerator pedal. This allows the vehicle to travel at a constant speed, reducing driver fatigue by removing the need to control the accelerator pedal, while also minimizing unnecessary speed variations and saving fuel. Principle of cruise control: The cruise control system primarily works by the cruise control module reading pulse signals from the vehicle speed sensor and comparing them with the preset speed. Through precise electronic calculations, it issues commands to ensure the most accurate fuel supply for the vehicle at the set speed. Precautions for cruise control: Do not use the speed control system on roads with heavy traffic or poor road conditions (such as slippery surfaces, loose gravel roads, or roads after heavy rain). Once the system is activated and the speed exceeds 40 km/h, never shift the gear lever into neutral without depressing the clutch pedal, as this may cause the engine to over-rev and result in damage. If the set cruising speed is too high compared to the current traffic conditions, do not resume the set speed.

What are the two parts of a spoiler?

A spoiler includes the horizontal stabilizer and the vertical stabilizer, with a few models adopting a V-shaped spoiler. The function of a car spoiler: Professionally referred to as a rear wing, it is part of the car's aerodynamic kit. The main purpose of a car spoiler is to reduce the lift at the rear of the vehicle. If the lift at the rear is greater than that at the front, it can easily lead to excessive steering, reduced rear-wheel grip, and poor high-speed stability. Types of spoilers: Fiberglass spoilers: These spoilers come in various shapes, such as ducktail, wing-shaped, or straight-plate styles. They are relatively easy to shape, but fiberglass material is brittle, with poor toughness and rigidity, and is relatively inexpensive. Aluminum alloy spoilers: These spoilers offer good airflow guidance and heat dissipation effects, with a moderate price. However, they are slightly heavier than spoilers made of other materials. Carbon fiber spoilers: Carbon fiber spoilers have excellent rigidity and durability. They are not only lightweight but also the most aesthetically pleasing type of spoiler.

What is the reason for manual transmission high RPM fuel cut-off?

Manual transmission high RPM fuel cut-off is implemented to ensure the safe operation of the engine and to control fuel consumption and emissions. Hazards of excessively high RPM: At excessively high RPM, engine oil lubrication may become inadequate, increasing friction among rotating components and accelerating engine wear. Additionally, internal transmission components may malfunction, fail to operate normally, or even sustain damage, such as the timing belt or chain. Reasons for high RPM fuel cut-off: For gasoline-powered vehicles, when the RPM reaches the redline zone around 7000 and does not decrease even if the throttle is not released, the engine can no longer increase speed. However, the maximum speed is not limited by mechanical failure but rather by a preset limit in the engine control unit (ECU) to implement fuel cut-off. This prevents the driver from pushing the vehicle into the "danger zone," thereby protecting the engine.
