The Haval Jolion, in Elite trim and above, comes with a suite of electronic driver-assistance systems (ADAS) designed to improve safety and comfort on the road. Factory sensitivity settings, however, don’t always suit real-world driving conditions: some owners find that lane-departure warnings trigger too often, adaptive cruise control keeps an excessive following distance in dense city traffic, and lane-keep assist steers more insistently than they’d like. This guide brings together practical settings and real-world quirks of Jolion’s ADAS, including issues owners have discussed on enthusiast forums.
Which ADAS Features the Haval Jolion Offers, and What Determines the Set
It’s worth understanding upfront: the set of electronic assistants on the Jolion isn’t uniform across the lineup — it depends on trim level. Base versions include only mandatory safety systems: ABS, ESP, hill-start assist, and airbags. The extended ADAS package — lane keeping, adaptive cruise control, and surround-view cameras — becomes available starting with the Elite trim.
If a particular ADAS feature is missing from your multimedia menu, it most likely isn’t included in your specific trim — it can’t be enabled through software. The exact list of systems is defined by the trim specification.
According to the manufacturer’s official materials, the current Jolion lineup includes: a lane-departure warning system (LDW) with lane-keep assist (LKA) and lane-centering (LCK) functions; a system monitoring cross-traffic and blind spots (DOW) with rear collision warning (RCW); and adaptive cruise control (ACC) with a low-speed follow function (LSF), forward collision warning (FCW), automatic emergency braking (AEB), and traffic sign/pedestrian/cyclist recognition (TSR).
| System | Purpose |
|---|---|
| LDW (Lane Departure Warning) | Warns when the vehicle drifts out of its lane |
| LKA / LCK (Lane Keep Assist / Lane Centering) | Returns and holds the vehicle in the center of the lane |
| FCW (Forward Collision Warning) | Warns of a potential frontal collision |
| AEB (Automatic Emergency Braking) | Applies automatic emergency braking |
| ACC + LSF (Adaptive Cruise Control) | Adaptive cruise control, including low-speed following |
| TSR (Traffic Sign Recognition) | Recognizes signs, pedestrians, and cyclists |
| DOW (Blind Spot / Cross-Traffic Monitoring) | Monitors blind spots and cross-traffic |
| RCW (Rear Collision Warning) | Warns of a potential rear collision |
How to Open ADAS Settings in the Multimedia Menu
Adjusting sensitivity on most of these systems doesn’t require diagnostic equipment — the standard menu is enough:
- Turn on the ignition.
- Open the main screen of the infotainment system.
- Go to “Settings.”
- Select “Driver Assistance” (ADAS) — on some software versions this menu is labeled “Intelligent Driving” or “Driver Assistants” instead.
- Open the specific system to adjust its parameters.
Digging through this menu on the move to tune sensitivity for a specific road isn’t practical — some owners admit they eventually stop bothering with it altogether, either leaving the systems on default settings or simply swiping to disable individual functions from the screen.
Adjusting Lane Departure Warning (LDW)
This is one of the most frequently adjusted settings on the Jolion. The menu typically offers high, medium, and low sensitivity, plus a full off option.
When It Makes Sense to Lower Sensitivity
Reducing the LDW threshold is worth considering if warnings fire too often:
- on narrow roads;
- through road construction zones;
- in winter, when lane markings are hard to make out;
- on unpaved roads without any markings.
In practice, most owners find the medium sensitivity level to be the best compromise — fewer false triggers, while still catching genuinely risky situations.
Lane Keep Assist (LKA / LCK)
This system can actively steer the car back when it approaches a lane marking. On some firmware versions, the menu offers a range of intervention timing, from early to late; if the steering feels overly intrusive, choosing a later or gentler intervention mode helps.
It’s worth noting that LKA’s feature set has changed between firmware generations. On earlier, pre-facelift versions, lane keeping was split into three separate functions: warning, return-to-center, and lane centering. On the facelifted version, this level of detail disappeared from the menu — some owners have looked for ways to restore the earlier logic through third-party head-unit settings.

Adaptive Cruise Control Following Distance (ACC)
ACC lets you choose the following distance to the car ahead — typically 3 to 5 levels, from shortest to longest. It seems logical to use a short distance in the city and a longer one on the highway, but in practice it’s not that simple.
| Conditions | Recommended distance level |
|---|---|
| Dense city traffic | Shortest–short (see caveat below) |
| Light city traffic | Short–medium |
| Highway, higher speeds | Medium–longest |
Owners driving in cities with very dense traffic report that even the shortest ACC sensitivity setting triggers frequent following-distance warnings when moving just a few meters behind the car ahead. This happens because the factory ADAS thresholds are calibrated for less dense traffic than what’s typical in many large cities.
Based on a post on DRIVE2 (Russian-language source) — drive2.ru/l/716319731941904475
The practical takeaway: factory ACC levels are a starting point, not a strict rule — real-world comfort depends heavily on your city and typical traffic behavior. That said, an overly short following distance still reduces reaction time and isn’t advisable at higher speeds.
Forward Collision Warning (FCW)
FCW warns the driver of a potential collision with an object ahead. Early, standard, or late warning timing is usually selectable. If alerts feel too frequent in dense city traffic, switching to standard or late timing helps — as with ACC, dense urban traffic is usually the main driver behind excessive false alerts.
Automatic Emergency Braking (AEB)
On most Jolion versions, AEB operates largely automatically, with limited adjustment options: you can turn the system on or off, choose a warning mode, and in some cases adjust alert timing. Fully disabling AEB isn’t recommended — it’s designed as a last line of defense against driver inattention, and turning it off lowers the car’s overall level of active safety.
Blind Spot and Cross-Traffic Monitoring (DOW / BSD)
For blind-spot and cross-traffic monitoring, typical options include: standard mode, increased sensitivity, visual-only warnings, or combined visual and audible warnings. If audible alerts feel distracting in city driving, a reasonable compromise is to keep only the visual indicators in the mirrors active, rather than disabling the feature entirely.
Why ADAS Settings Sometimes Reset or the System Glitches
Some Jolion owners find that sensitivity settings revert to factory defaults after an engine restart, or that ADAS occasionally throws an error or temporarily switches off. Possible causes include:
- head-unit software updates;
- quirks specific to a particular firmware version;
- a multimedia system glitch or freeze;
- a physical obstruction in front of the windshield-mounted cameras.
Based on a post on DRIVE2 (Russian-language source) — drive2.ru/l/642135407537962748
If sensitivity settings reset consistently after every single restart — rather than occasionally due to weather conditions — it’s worth checking with an official dealer whether a head-unit firmware update addressing this exists.
Hidden ADAS Parameters and Diagnostics: Should You Touch Them?
In theory, diagnostic equipment can be used by specialists to adjust additional ADAS parameters — LKA steering intervention strength, warning trigger thresholds, feature activation speed, and adaptive cruise control logic. In practice, this is an uncommon procedure and isn’t always officially supported.
Changing ADAS parameters through diagnostic equipment, outside the standard menu, can affect how active safety systems perform and may give a dealer grounds to deny warranty coverage on the related components. This kind of intervention should only be considered with a full understanding of the consequences, ideally after consulting an official service center.
Recommendations for Haval Jolion Owners
Based on commonly reported experience, many owners settle on a similar balance of settings for everyday driving:
- LDW — medium sensitivity;
- LKA/LCK — later or gentler intervention;
- ACC — short to medium distance in the city, medium to longest on the highway, adjusted for the actual traffic density in your city;
- FCW — standard mode;
- DOW/BSD — visual and audible warnings, as long as they don’t become distracting;
- AEB — kept on at all times.
This balance typically delivers comfortable driving without an overwhelming number of alerts, while preserving the key active-safety functions.
Frequently Asked Questions
Not always through standard menus alone. Some owners report that LKA re-enables itself after every engine restart, even after being turned off manually during the previous drive.
In dense city traffic, even the shortest ACC setting can feel excessive — this is especially noticeable for owners driving Jolion models in large cities with very heavy traffic flow.
A common cause is ice or dirt covering the camera area behind the windshield, or bright sunlight hitting the lens directly. Once the windshield is cleared or warmed up, the cameras resume working.
Yes. The extended ADAS package is available from the Elite trim and above; base versions include only mandatory safety systems — ABS, ESP, hill-start assist, and airbags.
Conclusion
The Haval Jolion’s driver-assistance systems noticeably improve safety on the road, but their factory settings don’t suit every driving environment — particularly dense urban traffic conditions common in many of the markets where the Jolion is sold. Through the multimedia menu, you can adjust LDW sensitivity, ACC following distance, and lane-keeping intervention, while also keeping in mind firmware-specific quirks: some functions can reset after a restart or temporarily disable due to the condition of the windshield cameras. The sensible approach is to tune the system to your own driving style and conditions, without disabling core active-safety functions like AEB.
