| Air Filter | AMBER | The air filter restriction indicator alerts that the engine air filter is clogged, reducing airflow and fuel efficiency in the DAF XF. | Replace the air filter according to the maintenance schedule. | |
| Fuel Filter / Water Separator | AMBER | This light signals that the fuel filter is restricted or water has separated, which can impair engine performance. | Drain any water and replace the fuel filter if needed. | |
| Service / Hour Meter | AMBER | A service interval reminder appears as a wrench icon, indicating that scheduled maintenance is due on the DAF XF. | Schedule a service appointment based on the hours displayed. | |
| Work Lights | GREEN | The work lights indicator shows that auxiliary lighting for loading or unloading is active. | Turn off work lights when driving on public roads to avoid blinding others. | |
| Differential Lock | AMBER | The differential lock is engaged to improve traction on slippery surfaces; avoid cornering with it locked in the DAF XF. | Disengage the diff lock once you regain traction to prevent driveline damage. | |
| PTO Engaged | GREEN | The power take-off is engaged, supplying hydraulic or mechanical power for auxiliary equipment. | Ensure the vehicle is stationary and the parking brake is on before operating PTO. | |
| Air Brake Pressure (Low) | RED | Low air pressure in the brake system can cause brakes to lock or fail; the DAF XF's air brake system requires a minimum pressure to release the parking brake. | Wait for the air pressure to build before driving; if it doesn't rise, call for service. | |
| Engine / Exhaust Brake | GREEN | The exhaust brake or retarder is active, providing additional braking force on descents to save service brakes. | Use the retarder to maintain speed control; it can be turned off if not needed. | |
| Trailer | GREEN | The trailer lamp indicates that the electrical connection to the trailer is established and operational. | If the light is missing when connected, check the trailer plug and wiring. | |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Radiator blockage
- Thermostat failure
What to do
Pull over and let the DAF XF idles for a few minutes; if the temp stays high, shut down and check coolant. Once cooled, top off coolant or clean the radiator. Do not drive until normal.
Air Brake Failure
Common causes
- Compressor fault
- Leaking air line
- Moisture in system
What to do
Immediately stop in a safe location; never drive with low air pressure. Call for roadside assistance to inspect the air system; the DAF XF's brakes may lock if pressure drops below 4.1 bar.
Engine Oil Pressure Loss
Common causes
- Low oil level
- Oil pump failure
- Clogged oil filter
What to do
Shut off the engine immediately to prevent catastrophic damage. Check oil level and add if low; if the light remains, have the pump and filter serviced by a DAF technician.
DEF/AdBlue System Failure
Common causes
- Empty AdBlue tank
- Crystallized injector
- Faulty NOx sensor
What to do
Refill AdBlue if low; if the light persists with a countdown, the vehicle will eventually limit speed. Visit a DAF dealer to diagnose the SCR system and replace components as needed.
Electrical Charging Fault
Common causes
- Alternator failure
- Broken serpentine belt
- Weak battery
What to do
Try to minimize electrical loads and drive to the nearest service point. If the battery warning remains, the DAF XF may stall; use jumper cables if needed, but have the alternator tested.
Frequently Asked Questions
Why does my DAF XF show a red stop light and then go into limp mode?
This indicates a critical fault, such as low oil pressure or brake system failure. The truck intentionally limits power to protect components. Use the driver display to read the fault code; if it's the AdBlue system, refill fluid or have the sensor replaced.
What does the amber DPF light mean and how do I regenerate?
The DPF light means the diesel particulate filter is accumulating soot. If it's solid, drive at highway speeds for 20 minutes to regenerate passively. If flashing, perform a parked regeneration: stop, engage parking brake, press the regen button in the cab, and wait 30–60 minutes.
How do I know when to perform a parked regeneration on the DAF XF?
The DPF light flashes when filter load is high, and the vehicle may display 'DPF full, regen required' on the cluster. Ensure the truck is parked on a non-flammable surface, engine hot, and no active PTO.
Why does my AdBlue warning show a 500-mile countdown?
The SCR system estimates remaining distance before power is reduced. Refill AdBlue as soon as possible. Using non-genuine AdBlue can cause crystallization; always use certified fluid for the DAF XF.
Can I continue driving if the ABS light is on?
Yes, but the anti-lock braking system is disabled. You still have normal braking, but on slippery roads the wheels may lock. Drive cautiously and book a service to check wheel speed sensors.
What should I do if the battery light comes on while driving?
The alternator may not be charging. Turn off non-essential electrical loads (lights, AC) and drive to the nearest workshop. A failing belt or alternator can leave you stranded; check belt tension if accessible.
