| Brake System | RED | A fault in the Hi-Road's brake circuit or low brake fluid is detected. | Stop safely and check brake fluid reservoir; do not drive without brakes. | |
| ABS | AMBER | The Hi-Road's anti-lock braking system has a malfunction. | Standard brakes remain; service ABS sensor or module at your Iveco dealer. | |
| Parking Brake | RED | The Hi-Road's parking brake is engaged or a fault is preventing release. | Ensure parking brake is fully released; if light persists, service brake valves. | |
| Tire Pressure (TPMS) | AMBER | One or more tires on the Hi-Road have low pressure or sensor error. | Check and inflate tires to recommended pressure; inspect for damage. | |
| Airbag (SRS) | AMBER | The Hi-Road's supplemental restraint system has a fault. | Have the airbag system inspected by a qualified technician. | |
| Seat Belt | RED | The driver's seat belt in the Hi-Road is not fastened. | Fasten your seat belt before driving. | |
| Glow Plug / Preheat | AMBER | The Hi-Road's glow plugs are preheating the engine for cold starts. | Wait until the indicator turns off before starting the engine. | |
| DPF / Regeneration | AMBER | The Hi-Road's diesel particulate filter is regenerating to clean itself. | Continue driving at highway speed to complete the process; do not turn off. | |
| DEF / AdBlue | AMBER | The Hi-Road's AdBlue level is low or the SCR system has a fault. | Refill AdBlue tank; if light stays, service SCR system. | |
| Water in Fuel | AMBER | Water has accumulated in the Hi-Road's fuel filter/water separator. | Drain water from the separator immediately to prevent injection damage. | |
| Low Fuel | AMBER | The Hi-Road's fuel level is low; reserve remaining. | Refuel as soon as possible to avoid running out. | |
| High Beam | BLUE | The Hi-Road's high beam headlights are activated. | Dim when approaching other vehicles. | |
| Reduced Power (Limp Mode) | AMBER | The Hi-Road's engine power is reduced to protect the drivetrain. | Drive to a service area; check engine and transmission codes. | |
| Engine Oil Temperature | RED | The Hi-Road's engine oil temperature is dangerously high. | Stop engine and let it cool; check oil level and cooling system. | |
| Air Filter | AMBER | The Hi-Road's air filter is clogged or needs servicing. | Replace or clean air filter to maintain engine performance. | |
| Fuel Filter / Water Separator | AMBER | The Hi-Road's fuel filter requires service or water drainage. | Replace fuel filter or drain water; refer to maintenance schedule. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due on your Hi-Road based on engine hours. | Service the truck according to the Iveco Hi-Road maintenance plan. | |
| Air Brake Pressure (Low) | RED | Air brake pressure in the Hi-Road's system is below safe operating level. | Stop; let compressor build pressure; check for air leaks. | |
| Engine / Exhaust Brake | GREEN | The Hi-Road's auxiliary braking system (retarder or exhaust brake) is active. | No action needed; it assists in downhill braking. | |
| Trailer | GREEN | A trailer is electrically connected to the Hi-Road's system. | Verify trailer lights and connections are operational. | |
| High Exhaust Temp (HEST) | AMBER | The Hi-Road's exhaust system is at high temperature, often during regeneration. | Avoid parking over dry grass or flammable materials. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Faulty thermostat
- Radiator blockage
What to do
For the Hi-Road, pull over, let engine idle in neutral, check coolant level and fan operation; if persists, service at Iveco dealer.
Brake Failure
Common causes
- Low air pressure
- Brake fluid leak
- Worn brake pads
What to do
Immediately stop and do not drive. For Hi-Road with air brakes, check air tanks and lines; refill brake fluid if equipped; have system diagnosed.
Low Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Clogged oil filter
What to do
Shut down the Hi-Road's engine immediately. Check dipstick; top up oil with correct grade; if light stays, tow to service center.
Electrical System Failure
Common causes
- Dead battery
- Alternator fault
- Loose wiring
What to do
Attempt to jump-start the Hi-Road; if no dash lights, check battery connections. Replace alternator if charging system remains faulty.
Transmission Overheat
Common causes
- Low transmission fluid
- Overloaded truck
- Faulty cooler
What to do
Stop the Hi-Road and shift to neutral; let transmission cool. Check fluid level and for leaks; reduce load; service transmission cooler.
Frequently Asked Questions
What does the DPF regeneration light mean on my Iveco Hi-Road?
It means the diesel particulate filter is cleaning itself by burning off soot. Drive at highway speed until the light turns off; avoid turning off the engine during regeneration.
Why is my Hi-Road's check engine light on after refueling?
Probably a loose fuel cap or poor quality fuel. Tighten the cap; if light persists, the ECU may need clearing at an Iveco service center.
Can I drive with the ABS warning light on?
Yes, but anti-lock brakes are disabled. Drive cautiously and have the system checked at your earliest convenience at an Iveco dealership.
What should I do if the master warning (stop) light comes on?
Stop the Hi-Road as soon as safely possible. Check the central display for the specific fault—common issues include low oil pressure or high coolant temperature.
How often should I drain water from the fuel filter on a Hi-Road?
Every 10,000 km or when the water-in-fuel warning appears. Use the drain valve on the fuel filter/water separator to avoid injection damage.
My Hi-Road's AdBlue light is on but the tank is full. What's wrong?
The SCR system may have a malfunction. Drive to a service center; continued use without AdBlue treatment can limit engine power.
