The dashboard of the Iveco Daily displays several dozen warning symbols, each connected to a sensor or an onboard computer. Their role goes beyond simple warning: they translate in real-time the status of the engine, transmission, braking circuit, and pollution control systems. Understanding the meaning of these indicators on the Iveco Daily allows for timely intervention before a minor fault turns into prolonged immobilization.
SCR and AdBlue Indicators on Iveco Daily: Pollution Alerts Not to Be Ignored
Competitors often list indicators by color or mechanical function. They frequently overlook a technical point that has become central in recent Daily models: the SCR (Selective Catalytic Reduction) system and its alerts related to AdBlue.
Since the Euro 6 standard, the computer continuously monitors the urea level in the dedicated tank and the proper functioning of the injection system. When a fault is detected or the AdBlue level drops below a critical threshold, a regulated alert sequence is triggered. This sequence, governed by EU regulation 2018/1832, follows a specific order:
- An orange pre-alert appears to signal a low level or malfunction of the SCR circuit. The vehicle operates normally, but the driver has a limited time to act.
- A reinforced alert is displayed if no action is taken. The light turns red or blinks, sometimes accompanied by a text message on the multifunction display.
- A countdown of remaining starts is activated as a last resort. Once this counter reaches zero, engine torque may be restricted or restarting blocked.
Ignoring the first SCR alert level exposes the driver to a gradual power limitation. On a loaded utility vehicle, the loss of torque is immediately felt when climbing or on the highway. For a deeper understanding of each symbol, a list of indicators on the Iveco Daily details all the pictograms present according to the model generations.

ADAS Indicators and Active Safety: The New Symbols on the Dashboard
The latest Iveco Daily models are equipped with advanced driver assistance systems whose indicators were absent in previous generations. Their presence stems from European regulation 2019/2144 (GSR2), which gradually mandates active safety devices on new utility vehicles starting in 2024.
Three categories of ADAS indicators now appear on the instrument cluster:
Autonomous Emergency Braking (AEB)
The AEB indicator lights up briefly at startup to confirm that the system is operational. If it remains lit in orange while driving, the front sensor (radar or camera) is obstructed or malfunctioning. The autonomous braking is then disabled, removing a layer of protection in case of inattention.
Lane Departure Warning (LDWS)
This indicator, often represented by two parallel lines with a deviating vehicle, signals that the system is monitoring the road markings. A change to orange or red indicates either a voluntary deactivation or a fault in the lane reading camera. On highways and fast lanes, this alert helps limit unintentional lane departures.
Tire Pressure Monitoring System (TPMS)
The TPMS indicator represents a tire cross-section with an exclamation point. A steady orange light signals a loss of pressure in at least one tire. A blinking light indicates a malfunction of the sensor itself. On a loaded Daily, insufficient pressure increases fuel consumption, accelerates wear, and degrades handling.
Engine and Cooling Circuit Indicators: Reading Red and Orange Alerts
The engine oil pressure indicator remains the most critical. Represented by an oil can, it lights up in red when the pressure in the lubrication circuit drops below the minimum threshold. Turning off the engine immediately is the only appropriate response. Continuing to drive, even for a few hundred meters, can cause irreversible seizing of internal parts.
The coolant temperature indicator operates on a similar logic. Blue at cold startup, it confirms that the engine has not yet reached its operating temperature. If it turns red, the temperature is abnormally high. The most common causes on the Daily are a stuck thermostat, a faulty radiator fan, or insufficient coolant level.
The “check engine” light (stylized engine in orange) covers a broader spectrum. It may signal an injection fault, a lambda sensor issue, an anomaly in the intake circuit, or a problem related to the turbocharger. An OBD diagnostic scan is then necessary to read the specific fault code stored by the computer.
Iveco Daily Natural Gas (CNG) Indicators: Specificities to Know
The Daily CNG versions add indicators specific to the compressed natural gas circuit. The symbol of a fuel pump accompanied by the mention “CNG” or a dedicated pictogram indicates the remaining gas level in the high-pressure tanks.
An orange indicator specific to the gas system may light up in case of a leak detected by the sensors or a fault in the shut-off solenoid. In this case, the computer automatically switches to backup gasoline mode (on bi-fuel versions) or limits power to protect the high-pressure circuit.
Checking the tightness of the connections and periodic inspection of the composite tanks are part of the specific maintenance for CNG versions. A persistent indicator on this circuit should never be treated by simply clearing the fault code without prior physical inspection.
The dashboard of the Iveco Daily has gained complexity with the introduction of Euro 6 pollution standards, mandatory ADAS systems, and alternative powertrains. Each indicator corresponds to a specific sensor and an alert logic calibrated by European regulation. Keeping the user manual handy in the glove compartment remains the simplest reflex to quickly associate an unknown symbol with the correct procedure.
