DAF 55CF Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical fault is detected on your DAF 55CF, such as engine or brake system failure, requiring an immediate stop. | Safely pull over and shut down the engine. Contact DAF service. | |
| Master Caution | AMBER | A non-critical system issue is present in the DAF 55CF, like low DEF level or a sensor fault, needing attention soon. | Check the message display and address the related system at the next stop. | |
| Check Engine (MIL) | AMBER | The DAF 55CF's engine management system has detected a fault that could affect emissions or performance. | Have the fault codes read by a DAF dealer to prevent further damage. | |
| Engine Oil Pressure | RED | Engine oil pressure is dangerously low on your DAF 55CF, risking severe engine damage. | Stop immediately and check oil level. Do not restart until resolved. | |
| Battery / Charging | RED | The alternator is not charging the battery on your DAF 55CF, or the voltage is out of range. | Continue to a service point; electrical systems may fail soon. | |
| Coolant Temperature | RED | Engine coolant temperature is above the safe limit for the DAF 55CF, risking overheating. | Reduce load and idle engine. If persists, stop and let cool. | |
| Transmission Temp | AMBER | The transmission fluid temperature is elevated on your DAF 55CF; avoid heavy use. | Shift to a lower gear and reduce speed. Allow transmission to cool. | |
| Brake System | RED | A serious fault in the brake system of the DAF 55CF, such as low air pressure or hydraulic failure. | Stop immediately. Do not drive until the brake system is inspected. | |
| ABS | AMBER | The Anti-lock Braking System on your DAF 55CF has a malfunction; standard brakes still work. | Drive cautiously to a DAF workshop for repair. | |
| Parking Brake | RED | The parking brake is engaged on the DAF 55CF or there is a system fault. | Release parking brake before moving. If light stays on, check brake status. | |
| Tire Pressure (TPMS) | AMBER | One or more tires on your DAF 55CF have low pressure or a sensor fault. | Check tire pressures at next stop; adjust or inspect sensors. | |
| Airbag (SRS) | AMBER | The Supplemental Restraint System on the DAF 55CF has a fault; airbags may not deploy. | Have the system inspected by a DAF dealer as soon as possible. | |
| Seat Belt | RED | The driver's seat belt is not fastened on the DAF 55CF. | Fasten your seat belt immediately. | |
| Glow Plug / Preheat | AMBER | The engine preheat system is active on your DAF 55CF; wait for it to turn off before starting. | Wait until the indicator goes out, then start the engine. | |
| DPF / Regeneration | AMBER | The Diesel Particulate Filter on your DAF 55CF is regenerating to clean trapped soot. | Keep the engine running and avoid stopping if possible; high exhaust temperatures. | |
| DEF / AdBlue | AMBER | AdBlue level is low on your DAF 55CF; refill to maintain emissions compliance. | Add DEF at next stop. If ignored, engine power may be reduced. | |
| Water in Fuel | AMBER | Water has been detected in the fuel filter/water separator of the DAF 55CF. | Drain the water separator as soon as possible to prevent injection damage. | |
| Low Fuel | AMBER | The fuel level in your DAF 55CF is low; refill soon to avoid running out. | Refuel at the next available station. | |
| High Beam | BLUE | The high beam headlights are on for the DAF 55CF. | Dim when approaching other vehicles. | |
| Power Steering (EPS) | RED | The electric power steering on your DAF 55CF has a fault; steering effort may increase. | Stop and have the system checked; avoid high speeds. | |
| Fasten Seat Belt | RED | The driver's seat belt reminder is active on the DAF 55CF. | Fasten your seat belt to continue. | |
| Reduced Power (Limp Mode) | AMBER | Engine power is limited on your DAF 55CF due to a detected fault to prevent damage. | Drive slowly to a service point; have the fault diagnosed. | |
| Air Brake Pressure (Low) | RED | Air brake system pressure is too low on the DAF 55CF; braking capability is reduced. | Stop immediately and wait for pressure to build. Do not drive until normal. | |
| Engine / Exhaust Brake | GREEN | The auxiliary braking system (retarder or exhaust brake) is active on your DAF 55CF. | Use to assist braking on descents; no action needed. | |
| Trailer | GREEN | A trailer is correctly connected and its electrical system is active on the DAF 55CF. | Verify trailer lights function; no further action. | |
| Door Open | RED | A door on the DAF 55CF is not fully closed. | Close all doors securely before driving. | |
| High Exhaust Temp (HEST) | AMBER | Exhaust temperature is high during DPF regeneration on your DAF 55CF; avoid driving over flammable materials. | Continue driving; park away from dry grass if regeneration finishes. |

Most Important Warning Lights
Engine Overheating
Common causes
- Coolant leak
- Failed thermostat
- Clogged radiator on DAF 55CF
What to do
Stop and let engine cool. Check coolant level and top up if safe. If recurring, have the cooling system inspected by a DAF technician.
Low Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Worn bearings in DAF 55CF engine
What to do
Immediately stop engine. Check oil level and add if low. Do not restart; call for DAF roadside assistance.
Air Brake Failure
Common causes
- Air leak in lines
- Compressor fault
- Moisture freezing on DAF 55CF
What to do
Stop safely. Allow air pressure to build if possible. If unable, do not drive; request a tow from DAF service.
DEF System Malfunction
Common causes
- Low AdBlue level
- Faulty NOx sensor
- DEF pump failure
What to do
Refill AdBlue if low. If light persists, have the system diagnosed at a DAF dealer to avoid power derate.
DPF Clogged
Common causes
- Short trips preventing regen
- Excessive idling
- Engine oil level too high
What to do
Drive at highway speeds to initiate regeneration. If light remains, visit a DAF workshop for forced regeneration.
Frequently Asked Questions
What does the amber engine light mean on my DAF 55CF?
It indicates an emissions-related fault. The DAF 55CF's ECU has detected an issue; drive to a dealer to read fault codes.
Can I drive if the DPF regeneration light is on?
Yes, but keep the engine running and maintain speed. The DAF 55CF is cleaning the filter; avoid stopping until it finishes.
Why does my brake warning light stay on after releasing the parking brake?
Possible low air pressure or a brake system fault on the DAF 55CF. Check air pressure gauge; if low, wait for buildup. If not, have brakes inspected.
How do I drain water from the fuel filter on a DAF 55CF?
Locate the water separator drain valve (usually on the filter housing). Open it via the knob or screw until clear fuel comes out, then close. Check manual for exact location.
What should I do if the AdBlue light comes on?
Refill AdBlue as soon as possible. On the DAF 55CF, if ignored, engine torque will be reduced. Add at least 10 liters to reset the warning.
Is it safe to drive with the ABS light on?
Yes, standard brakes work, but ABS is disabled. Drive cautiously on slippery roads and have the system repaired at a DAF dealer.
