The Nissan Diesel NV200, a reliable diesel van, features an instrument cluster with warning lights that help monitor vehicle health. Understanding these indicators is key to maintaining performance and safety. This guide explains the most common lights you'll encounter in the NV200.
Nissan Diesel NV200 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Check Engine (MIL) | AMBER | The engine control unit has detected a fault in the emission, fuel, or ignition system of your NV200. | Check fuel cap tightness; if light persists, have the system diagnosed by a Nissan dealer. | |
| Glow Plug / Preheat | AMBER | The glow plugs are heating the combustion chambers for cold start – wait until it turns off before cranking. | Turn ignition to ON position, wait for light to extinguish, then start engine. | |
| DPF / Regeneration | AMBER | The diesel particulate filter is actively regenerating to burn off soot; high exhaust temps are normal. | Drive at moderate speed to complete regeneration; avoid stopping immediately if safe. | |
| Water in Fuel | AMBER | Moisture has accumulated in the fuel filter/water separator – draining is needed to prevent injection damage. | Drain the water separator located near the fuel filter; consult NV200 manual for procedure. | |
| Low Fuel | AMBER | Fuel level is low; the NV200's range is limited, and running out may introduce air into the fuel system. | Refuel as soon as possible to avoid fuel system priming issues. | |
| Brake System | RED | A brake system fault detected – could be low fluid, worn pads, or hydraulic failure in the NV200. | Check brake fluid reservoir; if fluid is low, top off and inspect for leaks. Do not drive if brake pedal feels spongy. | |
| ABS | AMBER | The anti-lock brake system has a malfunction; standard brakes still work but ABS may not engage. | Have the ABS system inspected at a Nissan service center to restore full braking capability. | |
| Airbag (SRS) | RED | A fault in the supplemental restraint system – airbags may not deploy in a crash. | Immediately service the SRS system at a qualified workshop; do not ignore this warning. | |
| Seat Belt | RED | The driver's seatbelt is not fastened – the NV200's reminder will sound and light stays on until buckled. | Fasten your seatbelt immediately for safety and to silence the warning. | |
| High Beam | BLUE | The high-beam headlights are turned on, improving night visibility but may dazzle oncoming traffic. | Dim to low beam when approaching other vehicles to comply with road rules. | |
| Power Steering (EPS) | RED | The electric power steering system has a fault; steering may become heavy or lose assist. | Reduce speed and drive carefully to a service center; avoid sharp turns if steering feels stiff. | |
| Low Oil Level | RED | Engine oil level is low – insufficient lubrication can cause severe engine damage in the NV200. | Stop engine, check oil level with dipstick, add recommended oil if low, and inspect for leaks. | |
| Brake Fluid Level | RED | Brake fluid level is below minimum – this reduces braking efficiency and may indicate a leak. | Top up brake fluid with DOT 4 or as specified in NV200 manual; have system checked for leaks. | |
| Door Open | RED | One or more doors (including sliding side door) are not fully closed; warning light and chime activate. | Check all doors, including rear cargo doors, and close them securely. | |
| High Exhaust Temp (HEST) | AMBER | The exhaust gas temperature is elevated during DPF regeneration – normal but caution advised near flammable materials. | Park only on non-flammable surfaces; avoid parking over dry grass or leaves until light goes out. |

Most Important Warning Lights
Check Engine Light
Common causes
- Faulty oxygen sensor
- Loose or damaged fuel cap
- Diesel particulate filter blockage
What to do
For the NV200, ensure fuel cap is tight. If light persists, have the ECU scanned for codes at a Nissan dealer. Do not ignore as it can affect emissions and engine performance.
Brake System Warning
Common causes
- Low brake fluid
- Worn brake pads
- Hydraulic system leak
What to do
Check brake fluid reservoir under the hood. If low, add DOT 4 fluid and inspect for leaks. If brake pedal feels spongy, do not drive; call for roadside assistance.
Airbag Warning
Common causes
- Faulty occupant sensor
- Disconnected wiring under seat
- Failed control module
What to do
This system is safety-critical. Have the NV200's SRS diagnosed immediately by a certified technician. Do not attempt DIY repairs as airbags can deploy accidentally.
DPF Regeneration Stuck
Common causes
- Frequent short trips
- Engine not reaching operating temperature
- Exhaust restrictions
What to do
Drive the NV200 at highway speeds (50-60 mph) for 20-30 minutes to complete regeneration. If light continues, forced regeneration by a dealer may be required.
Water in Fuel
Common causes
- Contaminated diesel
- Condensation in tank
- Failed fuel cap seal
What to do
Drain the water separator located on the fuel filter housing. Consult the NV200 manual for the drain procedure; often a screw valve at the bottom of the filter.
Frequently Asked Questions
Why does the glow plug light stay on for a long time in my NV200?
In cold weather, the engine control unit may extend preheat time to ensure proper starting. If it stays on for more than 10 seconds without starting, have the glow plugs and relay checked.
Can I drive with the DPF regeneration light on?
Yes, but you should continue driving at moderate speed (above 30 mph) until the light turns off. Avoid stopping or idling to allow the regeneration cycle to complete.
What does the 'Water in Fuel' warning mean and how do I fix it?
It means water has accumulated in the fuel filter/water separator. Drain the separator by opening the valve at the bottom of the filter housing; check your NV200 manual for exact location.
Why is my ABS light on after changing a wheel on the NV200?
If the wheel speed sensor or wiring was disturbed, the ABS light may come on. The system should reset after a few drive cycles. If it persists, have the sensor alignment checked.
How often should I service the brake fluid on the NV200?
Nissan recommends brake fluid change every 2 years or 30,000 km (18,000 miles), whichever comes first, to maintain braking performance and prevent corrosion.
What should I do if the check engine light flashes on my NV200?
A flashing check engine light indicates a severe misfire or catalyst damaging condition. Reduce speed and have the vehicle towed to a service center immediately to avoid costly repairs.
