The AdBlue® system is designed to alert you when the fluid level is low. The following steps outline the actions required based on the remaining range:
- Between 1,500 miles and 500 miles (2,400 km and 800 km): Top up the AdBlue® as soon as possible. A warning lamp will light up, accompanied by a message reminding you to top up the fluid.
- Between 500 miles and 62 miles (800 km and 100 km): Top up the AdBlue® immediately to avoid the risk of engine starting prevention.
- Between 62 miles and 0 miles (100 km and 0 km): A top-up is vital as the engine will be prevented from starting once the AdBlue® is depleted. Add at least 10 liters of AdBlue® to the tank to restart the engine.
Note: It may take a few minutes of driving before the system detects the top-up and updates the range.
What Does a Malfunction of the SCR Emissions Control System Indicate in My Peugeot 508?
If there is a malfunction in the SCR emissions control system, you will be alerted by warning lamps, an audible signal, and the display of an “Emissions control fault” message. The alert is triggered while driving when the fault is detected for the first time, and thereafter when switching on the ignition for subsequent journeys, as long as the fault persists. If the fault is temporary, the alert will disappear during the next journey after self-diagnostic checks.
What Should I Do If the SCR System Malfunctions in My Peugeot 508?
If the SCR system fault indication remains after 31 miles (50 km) of driving, it confirms a fault. The AdBlue warning lamp will flash, and a message will display, indicating the remaining driving range before engine starting is prevented:
Up to 685 miles (1,100 km): You can continue driving, but have the system checked by a PEUGEOT dealer or a qualified workshop.
Starting Prevented: If the message “Emissions control fault: Starting prevented” is displayed every time the ignition is switched on, contact a PEUGEOT dealer or a qualified workshop to restart the engine.
Power Indicator
What Does the Power Indicator in a Peugeot 508 Hybrid Mean?
The power indicator in your Peugeot 508 Hybrid is a crucial tool that provides real-time feedback on how much power your vehicle is using and whether it is operating efficiently. Understanding the different zones on this indicator can help you optimize your driving style to achieve better fuel economy and make the most of your hybrid’s capabilities. The power indicator is divided into three distinct zones: POWER, ECO, and CHARGE.
POWER Zone:
The POWER zone on the indicator shows when your Peugeot 508 Hybrid is experiencing a high power demand. In this zone, the vehicle taps into both the petrol engine and the electric motor(s) to deliver the required performance. This is typically seen during periods of rapid acceleration, climbing steep hills, or when you need to achieve higher speeds quickly. The indicator slider will move into this zone when you engage in dynamic driving behaviors that require more energy.
While it’s normal for the indicator to enter this zone during certain driving conditions, consistently operating in the POWER zone may reduce the overall efficiency of your vehicle, leading to higher fuel consumption. It’s an indication that the vehicle is using more energy than it might in other driving modes.
ECO Zone:
The ECO zone represents the optimal balance of energy use in your Peugeot 508 Hybrid. When the indicator slider stays within this zone, it means that your vehicle is either operating efficiently on electric power or is making the best use of the petrol engine. The ECO zone is where you want to be most of the time to maximize fuel efficiency and reduce emissions. Driving in this zone not only conserves fuel but also prolongs the life of the vehicle’s components by reducing wear and tear.
Additionally, in hybrid mode, a symbol may appear indicating the threshold at which the petrol engine will engage. By paying attention to this symbol, you can adjust your driving style—such as reducing speed or pressure on the accelerator—to remain in electric mode longer, thus saving fuel and reducing emissions.
CHARGE Zone:
The CHARGE zone is where your Peugeot 508 Hybrid recovers energy and recharges the traction battery. This typically occurs during deceleration, when you lift your foot off the accelerator, or when braking. In this zone, the kinetic energy that would otherwise be lost as heat during braking is instead converted back into electrical energy and stored in the battery. This process, known as regenerative braking, helps extend the electric range of your hybrid and improves overall efficiency. The more you can make use of this CHARGE zone—by driving smoothly and anticipating stops—the more energy you can recover, which reduces the need to draw power from the petrol engine.
What Should I Do If My Peugeot 508 Hybrid Shows a High Power Demand?
If you notice that the power indicator frequently moves into the POWER zone while driving your Peugeot 508 Hybrid, it’s important to understand the context. High power demand is normal during certain driving situations, such as when you are accelerating onto a highway, overtaking another vehicle, or climbing a steep incline. During these times, the vehicle will naturally use more energy, and both the petrol engine and the electric motor(s) will work together to deliver the required power.
However, if your vehicle remains in the POWER zone for extended periods under normal driving conditions—such as when driving at a steady speed on flat terrain—it could indicate that the vehicle is working harder than necessary. This might be due to a number of factors, such as:
Driving Habits: Aggressive driving, frequent hard accelerations, and high-speed driving can keep the vehicle in the POWER zone more often, leading to decreased efficiency.
Terrain: Constantly driving on hilly or mountainous roads may naturally cause the vehicle to stay in the POWER zone as it requires more energy to climb inclines.
Vehicle Load: Carrying heavy loads or towing can increase power demands, pushing the indicator into the POWER zone.
Potential Mechanical Issues: If none of the above factors apply, and the vehicle consistently operates in the POWER zone, it might indicate an underlying issue with the hybrid system, such as problems with the battery, engine, or electric motor(s).
To address this, consider adopting a smoother driving style that emphasizes gradual accelerations and decelerations. Keep an eye on the indicator, and try to maintain your driving within the ECO zone as much as possible. If you find that the vehicle remains in the POWER zone despite your best efforts to drive efficiently, it may be wise to have the vehicle checked by a PEUGEOT Authorized Dealer or Service Center. They can run diagnostics to ensure that everything is functioning correctly and that there are no issues with the hybrid system or other components.
