🔰 Ford B-Max Dashboard Warning Lights:
The Complete Encyclopedia of Symbols, Colours & Solutions
Over 20 detailed warning lights explained — from engine management to AdBlue. Learn what each Ford B-Max dashboard symbol means, whether it’s safe to drive, and how to fix it. Includes model years 2012–2017 (MK1) and facelift.
📘 Definition: What Are Ford B-Max Warning Lights?
Dashboard warning lights are indicator lamps that notify the driver of vehicle status, malfunctions, or active systems. In the Ford B-Max (produced 2012–2017), these lights follow ISO 2575 but incorporate Ford‑specific icons. They are the primary way your car communicates issues like low oil pressure, failed ABS, or an open door. Understanding them helps prevent breakdowns and expensive repairs.
🌈 Types of Warning Lights (Colour = Urgency)
Every Ford B‑Max warning light falls into one of four colour categories:
- Red: Critical safety or mechanical failure – stop immediately. Examples: brake fluid low, airbag fault, engine overheating.
- Amber / Yellow: Malfunction or service required – check as soon as possible. Examples: engine management light (EML), tyre pressure, DPF.
- Green: System is active and working normally (turn signals, low beam, cruise control).
- Blue: Usually indicates high beam headlights are on.
Some symbols (like the master warning light – red triangle) appear with a message in the central display; always check that text.
📋 Complete A–Z of Ford B‑Max Dashboard Symbols
| Symbol | Name | Colour | Meaning & common causes | Driver action |
|---|---|---|---|---|
| ⚠️ | Check engine / EML | Amber | Engine, sensor, or emission fault. Causes: oxygen sensor, loose fuel cap, coil pack. | Check fuel cap; if flashing, stop. Use OBD2 scanner. |
| 🛢️ | Oil pressure | Red | Low oil level or pressure; oil pump failure. | STOP engine immediately – risk of seizure. |
| 🔋 | Battery charge | Red | Alternator not charging; broken belt or bad battery. | Turn off accessories, drive to garage; may stall. |
| 🛞 | TPMS (tyre pressure) | Amber | One or more tyres under‑inflated; sensor fault. | Check pressures, reset system via glovebox button. |
| 🛑 | Brake system | Red | Handbrake on, low brake fluid, or pad wear. | Release handbrake; if light persists, stop safely. |
| 🔄 | ABS | Amber | Anti‑lock brake system fault; wheel speed sensor. | Brakes work but no ABS; drive carefully to garage. |
| 💺 | Airbag / SRS | Red | Airbag system fault – may not deploy. | Repair immediately; diagnostic required. |
| 🌡️ | Coolant temp | Red | Engine overheating; low coolant, faulty thermostat. | Stop, let cool, check coolant level. |
| ⛽ | Glow plug (diesel) | Amber | Pre‑heat indicator; if flashing, glow plug fault. | Engine may be hard to start; check glow plugs. |
| 🔧 | Spanner / service | Amber | Scheduled maintenance reminder or transmission fault. | If steady, service due; if flashing, get transmission checked. |
| 🛞❄️ | Traction control (ESP) | Amber | System disabled or fault; button may have turned off. | Press TC button; if still on, have system scanned. |
| 🔺! | Master warning | Red | Accompanied by message (door open, low fuel, etc.). | Read message on centre display. |
| 💨 | DPF (diesel) | Amber | Diesel particulate filter clogged; short trips. | Drive at >40 mph for 20 min to regenerate. |
| 🧪 | AdBlue (diesel) | Amber/Red | Low AdBlue fluid or system fault. | Top up AdBlue; if ignored, engine won’t restart. |
| 🔑 | Key / immobiliser | Amber/Red | Key not recognised, or immobiliser fault. | Try spare key; hold key near steering column. |
| 🚗⛰️ | Hill start assist | Green | System active; brief flash when on hill. | Normal; if stays on, fault may exist. |
| ⚙️ | Power steering | Red/Amber | EPS fault; steering may become heavy. | If red, steering assist lost – service needed. |
| ❄️ | Frost warning | Amber | Outside temperature near freezing (below 4°C). | Caution: icy roads possible. |
| 🚙🔓 | Door / tailgate open | Red | One or more doors not fully closed. | Stop safely and close doors. |
| 💡 | Bulb failure | Amber | Exterior light (headlight, brake, indicator) failed. | Replace bulb soon. |
| 🚘 | Lane departure warning | Green/Amber | System on (green) or fault (amber). | If amber, check sensors/camera. |
Note: Some symbols vary by model year and optional equipment. Always verify with your owner’s manual.
🚦 How to React When a Warning Light Comes On
🟥 1. Identify colour
Red = safe stop. Amber = schedule check. Green/blue = enjoy.📟 2. Check message display
B‑Max central screen often gives text (e.g., “Low brake fluid”).🔧 3. Quick inspection (if safe)
Fluids, tyre pressure, obvious leaks.📱 4. Use OBD2 scanner
Read fault codes for exact cause – many auto stores offer free scanning.⚠️ Is It Safe to Drive with Warning Lights On? (By Colour & System)
Red lights (any): Not safe. Stop immediately. Examples: oil, coolant, brake, airbag, battery. Continuing can cause catastrophic damage or injury.
Amber lights: Usually safe for short trips, but don’t ignore. DPF light – drive to regenerate; Engine light – may affect emissions/fuel economy; ABS light – brakes work but no anti‑lock; TPMS – under‑inflated tyre unsafe at high speed.
Green/blue: Totally safe – they indicate normal operation (fog lights, high beam, cruise control).

🛠️ How to Use OBD2, Resets & Maintenance Tips
Most Ford B‑Max warning lights can be investigated with an ELM327 adapter and FORScan (free software). Common resets:
- Service spanner reset: Turn ignition on, fully press brake and accelerator for 30 seconds until spanner flashes.
- TPMS reset: Inflate tyres, press button in glovebox or use infotainment → settings → tyre pressure.
- Oil change reset: Sometimes via dashboard menu; or use diagnostic tool.
❓ Frequently Asked Questions – Expert Answers
📅 Model Year Differences (2012–2017)
Early B‑Max (2012–2015) may lack some lights like lane departure or pre‑collision. Facelift models (2015–2017) have more digital display and sometimes different icons. Diesel models include DPF and AdBlue lights (if equipped with SCR). Petrol models omit those.
