Baojun 730 cruise control cannot be used, possibly due to: damaged cruise switch, circuit failure (such as brake pedal sensor failure, wheel speed sensor failure, and related circuit failures, etc.); ECU cannot receive the signal from the cruise solenoid valve. How to use cruise control: Press the control switch to activate cruise control standby, accelerate to the desired speed, and then push the control lever down to set the cruise speed. To cancel cruise control, you can pull the control lever up, turn off the cruise control master switch, press the accelerator pedal, or lightly tap the brake. Conditions for using cruise control: It should be used on highways or fully enclosed roads. It is prohibited in rainy, snowy, or icy weather. It is also prohibited on mountain roads and curves. If there are too many vehicles on the road, it is not suitable for cruise control.

I've been driving my Baojun car for several years and have encountered quite a few instances of cruise control failure. There could be several main reasons: first, a blown fuse, which can be checked by simply looking at the fuse box; second, a speed sensor malfunction, which affects the system's ability to recognize the current speed; third, an issue with the brake switch—stepping on the brake should cancel the cruise control, but if the switch is faulty, the system remains inactive. It could also be due to aging control modules or wiring, where poor contact or short circuits interfere with signal transmission. Additionally, outdated software versions or user errors, such as attempting to activate cruise control beyond the speed limit, might cause failures. Last time I encountered this issue, it was due to rainwater corroding the wiring, and the repair shop fixed it by cleaning the connections. My advice is, if you experience cruise control failure, don't force it—first, pull over to check the fuses and connections, and if that doesn't help, visit a 4S shop for diagnosis. Safe driving is the top priority. During regular maintenance, ask the technician to inspect the cruise control components to prevent these issues—don't skimp on small expenses only to face bigger problems later.

Will Watering Brake Pads Cause Damage?

Watering brake pads at high temperatures can cause damage. Here are the specific requirements for brake pads: 1. Safety: Brake pads generate instantaneous high temperatures during braking, especially during high-speed driving or emergency braking. At high temperatures, the friction coefficient of the friction material decreases, which is called thermal fade. The level of thermal fade determines safety under high-temperature conditions and during emergency braking. 2. Lifespan: Typically, brake pads can last for 30,000 kilometers. 3. Friction Coefficient: The friction coefficient is a fundamental parameter of friction materials, determining the basic braking torque of the brake pads. The friction coefficient must be appropriate; too high can cause wheel lock-up, loss of directional control, and pad burning during braking, while too low can result in excessively long braking distances. According to national standards, brake pads should operate within a temperature range of 100°C to 350°C, with a friction coefficient around 0.4.

What Causes an Automatic Transmission Car Not to Move When Shifted into Reverse?

Possible reasons include the gear not being fully engaged, the vehicle's handbrake not being released, or the synchronizer in the transmission being stuck. First, check whether the gear is properly engaged. If there are no operational issues, it may require professional inspection. Here are additional details: 1. Poor driving habits: The vehicle not moving when shifted into reverse is often caused by poor driving habits, including inadequate maintenance. The first step is to check whether the gear is fully engaged. Many vehicles require pressing or lifting to shift into reverse to prevent accidental engagement. If shifting is difficult, check for any obstructions in the gear slot. 2. Vehicle malfunctions: After ruling out operational errors, consider potential vehicle malfunctions. Possible faults include reverse gear oil leakage, reverse gear or high-gear clutch failure, or brake system issues.
