Hino 195 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | This red warning illuminates when a critical fault is detected in the Hino 195, such as low oil pressure or overheating, and demands an immediate stop. | Safely pull over, shut down the engine, and do not restart until the issue is resolved. | |
| Master Caution | AMBER | In the Hino 195, this amber light alerts you to a less urgent fault that requires timely attention, often accompanied by an audible chime. | Check the message display for details and schedule service at your earliest convenience. | |
| Check Engine (MIL) | AMBER | The malfunction indicator lamp (MIL) on your Hino 195 signals an emission or engine performance issue that needs diagnostic review. | Have the engine scanned by a qualified technician as soon as possible to avoid reduced power or fuel economy. | |
| Engine Oil Pressure | RED | This red light in the Hino 195 indicates dangerously low engine oil pressure, which can cause catastrophic engine damage if ignored. | Stop the engine immediately, check oil level, and tow to a repair facility. | |
| Battery / Charging | RED | When lit on the Hino 195, it means the battery is not being charged properly, often due to a failing alternator or loose belt. | Check alternator belt tension and battery connections; replace if necessary. | |
| Coolant Temperature | RED | This red indicator warns that the engine coolant in your Hino 195 is overheating, risking head gasket failure. | Pull over, idle to cool down, and inspect coolant level and fan operation. | |
| Transmission Temp | AMBER | The amber light activates when the automatic transmission fluid temperature exceeds safe limits in the Hino 195, often when heavily loaded or climbing. | Reduce speed and shift to a lower gear to allow cooling; if it stays on, service transmission. | |
| Brake System | RED | This red warning on the Hino 195 indicates a hydraulic or air brake fault, potentially causing reduced braking effectiveness. | Test brakes immediately; if pedal feels soft, stop and call for roadside assistance. | |
| ABS | AMBER | The ABS warning light in your Hino 195 signals a malfunction in the anti-lock braking system, but normal braking remains functional. | Drive cautiously and have the system diagnosed to restore full safety features. | |
| Parking Brake | RED | This red light reminds you that the parking brake is engaged on the Hino 195—essential to release before driving. | Release the parking brake fully before moving the truck. | |
| Tire Pressure (TPMS) | AMBER | When illuminated on the Hino 195, one or more tires have low pressure, affecting fuel economy and handling. | Check tire pressures at the next stop and inflate to recommended levels. | |
| Airbag (SRS) | AMBER | This amber light indicates a fault in the supplementary restraint system of the Hino 195, which may prevent airbag deployment in a crash. | Schedule immediate inspection by an authorized Hino dealer. | |
| Seat Belt | RED | The seat belt reminder light flashes when the driver's belt is unbuckled in the Hino 195, with an accompanying chime. | Buckle your seat belt before driving. | |
| Glow Plug / Preheat | AMBER | This amber indicator stays on while the glow plugs are preheating the diesel engine in cold starting conditions for the Hino 195. | Wait for the light to turn off before cranking the engine. | |
| DPF / Regeneration | AMBER | When lit on the Hino 195, the diesel particulate filter needs regeneration due to excessive soot buildup; driving at highway speed often clears it. | If flashing, perform a parked regen per the owner’s manual; if solid, continue driving for 20 minutes above 30 mph. | |
| DEF / AdBlue | AMBER | This amber low-level warning in the Hino 195 indicates Def/DEF level is low and if ignored, will lead to speed limitation. | Add DEF immediately; do not let it run dry. | |
| Water in Fuel | AMBER | The water-in-fuel sensor on your Hino 195 has detected moisture in the diesel fuel system, which can damage injectors. | Drain the water separator or replace the fuel filter; if persistent, have the fuel system checked. | |
| Low Fuel | AMBER | This amber symbol on the Hino 195 illuminates when the fuel level drops below approximately 1/8 of a tank. | Refuel as soon as possible to avoid running out and potentially damaging the fuel system. | |
| High Beam | BLUE | A blue indicator shows the high beam headlights are activated on the Hino 195, for long-distance visibility. | Dim to low beam when approaching other traffic. | |
| Reduced Power (Limp Mode) | AMBER | In the Hino 195, this amber light signifies that the engine computer has limited power to protect the drivetrain from damage. | Reduce speed and proceed to a service facility; check for active DPF regen or DEF issues. | |
| Air Brake Pressure (Low) | RED | A critical red warning on the Hino 195 that air brake pressure is too low for safe operation, often after parking brake release. | Stop immediately and allow air pressure to build; if it drops while driving, pull over and call for help. | |
| Engine / Exhaust Brake | GREEN | This green light indicates the exhaust brake (retarder) is active on the Hino 195, assisting in slowing the truck without using service brakes. | Use on long downgrades to reduce brake wear; can be toggled manually. | |
| Door Open | RED | The red indicator shows that the driver’s door of the Hino 195 is not fully closed, which can also cause the interior light to stay on. | Close the door securely before driving. | |
| Washer Fluid Low | AMBER | This amber light in the Hino 195 warns that the windshield washer fluid reservoir is nearly empty. | Top up with appropriate washer fluid to maintain visibility. |

Most Important Warning Lights
Check Engine Light On with Power Loss
Common causes
- Faulty EGR valve
- Clogged DPF filter
- Bad fuel injector
What to do
For the Hino 195, first check if the DPF regen is needed; if not, take to a Hino dealer for diagnostic scan and component replacement as necessary.
Red Brake Warning Light
Common causes
- Low brake fluid
- Air in brake lines
- Worn brake pads
What to do
Check brake fluid level in the reservoir and inspect for leaks on the Hino 195; if fluid is low, top up and have the brakes inspected for wear.
Engine Overheating (Red Coolant Light)
Common causes
- Low coolant level
- Radiator fan failure
- Coolant pump belt slip
What to do
Immediately stop the Hino 195, check coolant level after engine cools, and inspect the fan belt tension; refill coolant and replace belt if glazed.
Transmission Over Temp (Amber)
Common causes
- Heavy load on steep grade
- Low transmission fluid
- Faulty cooling circuit
What to do
Shift to a lower gear and reduce engine load; if the Hino 195's transmission light persists, check fluid level and consider auxiliary transmission cooler installation.
DPF Regen Light Flashing
Common causes
- Frequent short trips
- Low exhaust temperature
- Sensor malfunction
What to do
On the Hino 195, perform a parked regeneration by following the menu prompts; if it fails, clean or replace the DPF and check exhaust temperature sensors.
Frequently Asked Questions
What does the Master Warning (Stop) light mean on my Hino 195?
It means a critical fault has occurred, such as low oil pressure or overheating. You must pull over safely and shut off the engine immediately.
Why is my Check Engine light flashing on the Hino 195?
A flashing Check Engine light indicates a severe misfire that could damage the catalytic converter. Reduce speed and have the truck towed to a repair shop.
How do I know when to perform a DPF regen on the Hino 195?
When the amber DPF light comes on steady, drive at highway speeds for 20 minutes. If it flashes, stop and initiate a parked regen via the instrument panel.
Can I ignore the DEF low warning on the Hino 195?
No, if ignored, the Hino 195 will limit your speed to 5 mph once the DEF runs dry. Always refill with approved DEF fluid.
What should I do if the ABS light stays on after starting my Hino 195?
The anti-lock braking system is disabled, but normal brakes still work. Have the system scanned at a Hino dealer to avoid skidding risk.
Is it normal for the exhaust brake light to be on while driving downhill?
Yes, the green exhaust brake indicator shows the retarder is active, reducing brake wear. It turns off when you disengage the system.
