The DAF 65CF’s instrument cluster is designed for clarity and quick diagnosis, with a tachograph-integrated display. Color-coded warnings help drivers prioritize issues: red for immediate stop, amber for service soon, and green/blue for active systems. Familiarity with these symbols ensures safe operation and minimizes downtime.
DAF 65CF Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A serious fault detected on your DAF 65CF; the central display shows the specific issue. | Stop safely immediately and consult the warning on the multi-function display. | |
| Master Caution | AMBER | Non-critical fault or system out of spec on the 65CF; additional info is shown on the cluster. | Check the display and schedule service soon. | |
| Check Engine (MIL) | AMBER | Engine management system detected an emission or performance issue on your DAF 65CF Paccar engine. | Have the engine diagnosed by a DAF dealer to prevent reduced power. | |
| Engine Oil Pressure | RED | Oil pressure is too low, risking engine damage on the 65CF’s Paccar MX engine. | Stop engine immediately; check oil level and leaks. | |
| Battery / Charging | RED | Alternator or battery system malfunction: battery not charging properly on your 65CF. | Check alternator belt and battery connections; drive to service if voltage drops. | |
| Coolant Temperature | RED | Engine coolant temperature is dangerously high, possibly due to blockage or low coolant in the 65CF. | Stop and let engine cool; check coolant level and radiator for leaks. | |
| Brake System | RED | Brake system fault, low air pressure or fluid level detected on your DAF 65CF. | Stop safely; check air system and brake fluid reservoir. | |
| ABS | AMBER | Antilock Braking System fault on the 65CF; normal braking still works but ABS disabled. | Drive to workshop; ABS control unit or wheel speed sensor may need inspection. | |
| Parking Brake | RED | Parking brake is applied or there is a fault in the spring brake system on the 65CF. | Release parking brake before driving; if light stays, check air pressure. | |
| Airbag (SRS) | AMBER | Supplemental Restraint System fault in your DAF 65CF; airbags may not deploy in an accident. | Have the system diagnosed by a DAF dealership immediately. | |
| Seat Belt | RED | Driver’s seat belt is not fastened while driving the 65CF. | Fasten seat belt; the reminder will clear. | |
| Glow Plug / Preheat | AMBER | Preheat system is active or a glow plug fault exists on the 65CF Paccar engine. | Wait for preheat to finish; if flashing, have glow plugs checked. | |
| DPF / Regeneration | AMBER | Diesel Particulate Filter is regenerating or needs cleaning on your DAF 65CF. | If blinking, perform a parked regen; if steady, drive at high RPM to clear. | |
| DEF / AdBlue | AMBER | AdBlue level is low or system fault, affecting emissions compliance on the 65CF. | Top up DEF fluid; if light persists, check DEF injector. | |
| Water in Fuel | AMBER | Water detected in the fuel filter/water separator on your DAF 65CF. | Drain water from the separator; if persistent, replace fuel filter. | |
| Low Fuel | AMBER | Fuel level is critically low on the 65CF; you may run out soon. | Refuel as soon as possible to avoid air in the system. | |
| High Beam | BLUE | High beam headlights are switched on in your DAF 65CF. | No action needed; use when road conditions allow. | |
| Power Steering (EPS) | RED | Electric power steering fault detected on the 65CF; steering effort may increase. | Stop safely; EPS system may require recalibration. | |
| Air Brake Pressure (Low) | RED | Air brake system pressure is below safe operating level on your DAF 65CF. | Wait for compressor to build pressure; if light stays, check for leaks. | |
| Engine / Exhaust Brake | GREEN | Exhaust/engine brake is active on the 65CF, reducing speed without service brakes. | Use on downgrades; if light flashing, system may have a fault. | |
| Trailer | AMBER | Trailer connection or ABS issue detected on the 65CF towing circuit. | Check trailer plug and lights; inspect trailer ABS. | |
| Door Open | RED | A cab door is not fully closed on your DAF 65CF while vehicle is moving. | Stop and close all doors securely. | |
| High Exhaust Temp (HEST) | AMBER | Exhaust aftertreatment system is hot due to regen or high load on the 65CF. | Avoid parking over dry grass; no immediate action needed. |

Most Important Warning Lights
Engine Overheat
Common causes
- Low coolant level
- Coolant leak
- Radiator blockage or fan failure
What to do
Stop the engine immediately and let it cool. Check coolant expansion tank for level; add coolant if safe. Inspect for leaks in hoses or radiator. If recurring, have the thermostat and water pump inspected at a DAF dealer.
Low Oil Pressure
Common causes
- Low engine oil level
- Oil pump failure
- Clogged oil filter or passage
What to do
Stop the engine immediately to avoid damage. Check oil level with dipstick; top up with correct grade (SAE 15W-40 typically). If light remains, do not drive—tow to DAF service for oil system diagnosis.
Brake System Failure
Common causes
- Air leak in brake circuit
- Low brake fluid level
- Worn brake pads or actuator failure
What to do
Stop safely and press brake pedal to test firmness. Check air pressure gauge if equipped; if low, wait for compressor. For fluid loss, check master cylinder reservoir. Only proceed if brakes are functional; otherwise, request roadside assistance.
Battery/Charging Fault
Common causes
- Broken alternator belt
- Faulty alternator
- Loose or corroded battery terminals
What to do
Check belt tension and condition; replace if loose. Clean battery terminals and tighten connections. If warning persists, have the alternator output tested—common issue on 65CF with high electrical loads.
DEF/AdBlue System Fault
Common causes
- Empty DEF tank
- Contaminated DEF fluid
- Faulty DEF injector or pump
What to do
Fill DEF tank with quality fluid (ISO 22241). If light remains, a diagnostic scan at a DAF dealer is required; the system may limit power after 50 km.
Frequently Asked Questions
Why does my DAF 65CF show a red stop light but no message?
The red master warning indicates a serious fault even without a specific text. Pull over safely and use the ‘i’ button on the cluster to cycle through any stored codes. If none appear, the issue may be intermittent but still requires dealer attention.
What should I do if the DPF regen light stays on permanently?
A steady amber DPF light means the filter is partially blocked. Drive at highway speed (above 60 km/h) for 15-20 minutes to initiate passive regeneration. If it switches to flashing, you must perform a parked regen using the switch on the dashboard while stationary.
How often should I drain the water separator on my 65CF?
It is recommended to drain the water separator every 5000 km or weekly in humid conditions. A water-in-fuel warning means you should drain it immediately by turning the plastic knob at the bottom of the filter housing until clean fuel flows.
Can I drive with the ABS light on?
Yes, but only to a workshop. The brake system will still function normally, but ABS, traction control, and stability assist will be disabled. On slippery roads, exercise extreme caution and have the wheel speed sensors checked.
My DAF 65CF won’t start and the glow plug light flashes. What’s wrong?
A flashing glow plug light indicates a fault in the preheat system, often due to a blown fuse or defective glow plugs. Check the preheat relay and fuse box under the dash. If you are in cold weather, you may need to cycle the key several times before starting.
What does it mean when the exhaust brake light is green but not slowing the truck?
The green light indicates the exhaust brake is armed, but it only activates when you release the accelerator or press the brake pedal. On the 65CF, check the clutch switch if it fails to engage; if the light blinks, there is a system fault that requires diagnosis.
