How to Use the Cruise Control on Hongqi H9?

[SilasMarie]

Press the control switch to activate the cruise control standby mode. After accelerating to the desired speed, push the control lever downward to set the cruising speed. To accelerate, push the lever upward or press the accelerator pedal. To cancel the cruise control, lift the control lever upward, turn off the main cruise control switch, press the accelerator pedal, or lightly tap the brake. Additional information about cruise control is as follows: 1. Purpose: Cruise control automatically maintains the vehicle's speed as set by the driver without the need to press the accelerator pedal, allowing the car to travel at a fixed speed. This eliminates the need for the driver to control the accelerator pedal, reducing fatigue and unnecessary speed fluctuations, which can save fuel. 2. Principle: The principle of the cruise control system mainly involves the cruise control component reading the pulse signal from the speed sensor and comparing it with the set speed. Through precise electronic calculations, it issues commands to ensure the most accurate fuel supply for the vehicle at the set speed.

To be honest, the adaptive cruise control on the Hongqi H9 is really easy to use, and I love using it for long-distance drives. You can activate it once you're driving above 40 km/h. First, find the button with the small speedometer icon on the left side of the steering wheel and press it—the cruise indicator light will turn on. Then, push the RES/SET minus button downward, and the car will memorize the current speed and start cruising. To adjust speed, you don’t need to press the accelerator; just use the '+' or '-' buttons for fine-tuning—each press changes the speed by about 2 km/h. If you need to overtake, pressing the accelerator won’t disrupt the system; once you release it, the car will automatically return to the set speed. A quick reminder: pressing the brake or the CANCEL button will pause the cruise control, but to fully turn it off, you’ll need to press the original speedometer button again.

I've been driving this Hongqi H9 for almost two years and have mastered all the details of its cruise control. The key is that row of buttons on the left side of the steering wheel: find the main switch with the speedometer icon to activate the system, and a white light will illuminate on the dashboard as a prompt. When you reach an appropriate speed (usually not feasible in urban areas), push down the lever marked 'SET' to lock in the speed. To accelerate, gently push the '+' button upwards, and holding it down will provide continuous acceleration. Here's a handy tip: if you want to resume your previous speed after stopping at a red light, there's no need to reset - just push the RES lever upwards. There's also the steering wheel's sensing function - if your hands leave the wheel for too long, it will first vibrate and then automatically disengage the cruise control, which is quite a thoughtful design.

As a female car owner, I dread complicated operations, but the H9's cruise control is actually simple with just three steps: While driving, press the 'Cruise Main Switch' at the lower left of the steering wheel, and a white cruise icon will appear on the dashboard. Once you reach your desired speed, without taking your hands off the wheel, simply flick the adjacent 'SET-' downward. To accelerate, tap the '+' key; to decelerate, tap the '-' key. Note that hitting the brakes will pause the cruise, and you'll need to flick SET again to resume. In real-world testing, it's incredibly stable on highways—when following a car, it automatically slows down if the car ahead decelerates. Once, while using cruise control on a rainy day, the system suddenly reduced speed automatically. The dashboard showed it had detected standing water ahead—this proactive safety feature is truly reassuring.

Technical Perspective on the Hongqi H9 Cruise System: It utilizes household millimeter-wave radar detection, enabling full-speed range cruise activation at just 40km/h. The operation logic involves activation (CRUISE button) → setting (SET- button), with acceleration and deceleration adjusted via switch signals to the electronic throttle. The steering wheel is equipped with a capacitive sensor, triggering a tiered warning system if hands are off for over 15 seconds, eventually deactivating the cruise. Practical tests show the system's braking response at 120km/h takes only 0.3 seconds, with deceleration intensity adjustable across three levels. A notable detail is the automatic cruise deactivation when shifting to N gear or triggering automatic braking, preventing system conflicts. This solution significantly outperforms mechanical cruise systems in terms of safety.

After five years of repairing Hongqi vehicles, I remind owners to perform three checks before using cruise control: ensure tire pressure is accurate (a deviation exceeding 0.3bar affects distance measurement), clean the windshield immediately if dirty (the millimeter-wave radar is under the wiper), and replace brake pads if thickness is less than 5mm. When using it, note that the starting speed should preferably be ≥ 60km/h for more stable radar recognition. A common issue is that owners mistakenly think the system is broken after accidentally pressing 'CANCEL' to pause, but simply pressing the RES button can resume it. Also, in extreme cases where the system suddenly exits, it's likely triggered by the electronic stability program, so it's advisable to visit a 4S shop to read the fault codes. Although this feature is smart, manual driving is recommended for safer operation on slippery roads.
