JAECOO 7 petrol separates lane-departure warnings from steering intervention. Identify which function you want to change before adjusting it; switching off LDW alone is not a reliable way to stop every steering intervention.
Supported models and trims
JAECOO 7 petrol: Deluxe / Luxury, only where the described equipment is fitted
UK manual review; not a hands-on vehicle test. A missing menu may reflect equipment or software; this guide does not promise a feature can be enabled.
Before you begin
Park safely before changing settings. Match the powertrain, equipment and screen layout to the handbook for your own car. A manual describes possible equipment; it is not confirmation that every UK trim has it.
Step-by-step instructions
- Park, turn vehicle power to ON and open the audio system’s Driver assistance settings.
- For departure warnings, locate Lane assist system and its Lane departure reminder mode and sensitivity settings. The manual lists Sound, Vibration, Sound + Vibration and low/high sensitivity.
- For corrective steering, use the separately listed Lane departure prevention ON/OFF setting.
- Review Emergency lane keeping separately if you intend to change it. Do not assume the Lane assist system label is a master-off control for every steering aid.
- Confirm the chosen state on screen. The LDW chapter says the customer’s LDW choice is remembered, but recheck the other functions after restarting.
Three functions with different jobs
| Function | What it does |
|---|---|
| LDW: Lane Departure Warning | Warns about a lane departure. |
| LDP: Lane Departure Prevention | Can apply corrective steering as the car leaves its lane. |
| ELK: Emergency Lane Keeping | Can intervene in a potential road-edge or adjacent-traffic conflict; capability varies by model. |
Model and software notes
This is the July 2025 petrol interface. The handbook calls the warning function LDW in the system chapter but uses “Lane assist system” beside its warning settings in the menu summary.
Troubleshooting
- The steering still intervenes: distinguish LDW from LDP, ELK and active cruise assistance. Turning off a warning does not prove the other systems are off.
- The display is grey: the system may be enabled but limited or waiting for suitable conditions. Grey does not by itself mean a fault.
- A yellow fault indicator stays on: arrange inspection; do not try to fix it by repeatedly toggling the system.
- False warnings: check the camera’s view for dirt or ice and note the road markings. Persistent problems need retailer investigation.
Safety and limitations
- Keep both hands available to steer and remain responsible for the vehicle. Lane assistance is not autonomous driving.
- Do not deliberately cross a lane marking to test the setting. Make changes while parked.
- Poor markings, roadworks, sharp bends, bad weather and an obscured windscreen camera can reduce performance. Follow the handbook’s restrictions on using LDP.
