Peugeot 208 service, oil level, coolant, AdBlue and SCR indicators explained, plus the e-208 power, charge and thermal comfort gauges.
Most of the information on a Peugeot 208's instrument panel isn't a warning at all. The service spanner, oil level reading, temperature gauge and, on diesels, the AdBlue range readout are there to tell you how the car is doing before anything goes wrong. On the e-208 there's another set of gauges for power, battery charge and how much energy the heating is using.
This guide explains each of these readouts, what is normal, and when you need to act. It covers the second-generation 208 and e-208 (2019 on), using the official Peugeot 208 owner's handbook as our reference. For the coloured warning lamps, see our separate red and orange warning guides.
Here we cover indicators such as AdBlue, oil level and servicing. If you're seeing other types of warning on the instrument panel, we've covered them all separately, so make sure you also read our guides to Peugeot 208 orange warnings, Peugeot 208 red warnings and Peugeot 208 green and blue indicators.
The service indicator on the Peugeot 208 tells you that the car's routine service is due or coming up. It expresses the service interval in distance (kilometres or miles) and time (months or days), and it is triggered by whichever limit is reached first. A message appears on the instrument panel showing how far you can drive, or how long you have left, before the next service.
What to do:
Don't ignore the service indicator. Routine maintenance is vital for your car's performance, safety and longevity, so use the indicator as your cue to get the car serviced on time.
The maintenance spanner shows that your 208's next service is approaching. It appears briefly when you switch on the ignition and shows the distance remaining to the next routine service. If it shows a distance between 1,000 and 3,000 km, your next service will fall within that range. If the spanner stays on steadily with the ignition on, the next service is less than 1,000 km away.
What to do:
Responding promptly to maintenance indicators helps keep your car safe, long-lived and performing at its best.
A flashing service spanner, particularly on BlueHDi diesel models, warns that the service is overdue. With the ignition on, the spanner first flashes and then stays on steadily. It usually appears together with the Service warning lamp and means the car needs servicing straight away.
What to do:
The service indicator can be reset after every service. If you service the car yourself, follow these steps:
If you have any trouble resetting the indicator, contact a PEUGEOT dealer or qualified workshop.
You can view service information and reminders through the Driving/Vehicle touchscreen menu, which makes it easy to check service dates and maintenance details:
Regular servicing is essential to protect your car's performance, safety and longevity. If in doubt, contact a PEUGEOT dealer or qualified workshop.
Depending on version, the Peugeot 208 can check the engine oil level using an electric gauge. When you switch on the ignition, the oil level is shown on the instrument panel for a few seconds after the service information. It helps you confirm the engine has enough oil to run properly.
Digital instrument panel or Driving/Vehicle touchscreen: on versions with a digital instrument panel, you can press the "Check" button in the Driving/Vehicle touchscreen menu to view and configure some vehicle settings, including the engine oil level.
Checking the oil level regularly helps the engine last and keeps the car performing well. If the level is low or an oil change is due, contact a PEUGEOT dealer or qualified workshop.
This warning means the engine doesn't have enough oil. Depending on the instrument panel, the Service warning lamp comes on with an audible signal and an "OIL" or "Oil level incorrect" message. A low oil level can damage the engine and needs immediate attention.
What to do:
Low oil can cause the engine to overheat and suffer serious damage, so always take this warning seriously.
The "Oil level fault" warning means the engine oil level can't be measured correctly. Depending on the instrument panel, "OIL_ _" or "Invalid oil level measurement" is displayed, the Service warning lamp comes on and you hear an audible signal. It indicates a fault with the electric oil gauge, so the oil level can no longer be monitored electronically.
What to do:
Check the oil level manually: while the electric gauge isn't working, use the dipstick in the engine compartment. Park on level ground, let the engine cool, then pull out the dipstick, wipe it, reinsert it and check the level.
Keep up regular checks: with the electronic system out of action, manual checks become even more important.
If you have any concerns about your oil level or engine health, see a qualified workshop as soon as possible.
The coolant temperature gauge shows the temperature of the engine coolant. It is divided into two zones:
Zone A: the coolant temperature is normal.
Zone B: the coolant temperature is too high. The related warning lamp and the red STOP warning lamp come on, a message is displayed and you hear an audible signal.
What to do:
Overheating can cause serious engine damage, so if you get this warning, take the car to a PEUGEOT dealer or qualified workshop as soon as possible.
On Peugeot 208 BlueHDi models, the AdBlue® range indicators give information about the level of AdBlue® fluid, which the diesel engine's exhaust after-treatment needs to work properly. BlueHDi engines use SCR (Selective Catalytic Reduction) and a Diesel Particulate Filter (DPF) to treat exhaust gases, and these systems can't work without AdBlue®.
When the AdBlue® reserve falls below a certain level (2,400 km down to 0 km of range), a warning lamp comes on every time you switch on the ignition.
It shows the estimated distance you can drive before the engine is prevented from starting.
When the AdBlue® tank is completely empty, a system stops the engine from starting until the tank is refilled.
A low or empty AdBlue® tank affects the emission control systems the diesel engine needs to run cleanly and efficiently, so top up as soon as possible when you get a low-level warning. If you have any concerns, contact a PEUGEOT dealer or qualified workshop.
What you need to do depends on how far the AdBlue® level has fallen and how much range is left. Once the level drops below the reserve, specific warning lamps come on and messages remind you to refill so the engine isn't prevented from starting.
Range between 2,400 km and 500 km (1,500 miles and 800 miles):
Range between 800 km and 100 km (500 miles and 62 miles):
Range between 100 km and 0 km (62 miles and 0 miles):
Refilling and detection:
After you refill with AdBlue®, the system may not detect it straight away. It can take a few minutes of driving for the refill to be recognised.
The SCR (Selective Catalytic Reduction) emission control system on Peugeot 208 BlueHDi models cleans diesel exhaust gases to reduce air pollution. When a fault is detected in the SCR system, various warnings and messages appear on the instrument panel.
Fault detected:
The warning lamps come on with an audible signal and the message "Emissions fault" or "NO START IN".
This warning appears when the fault is first detected, then every time you switch on the ignition for as long as the fault persists.
If the fault is temporary:
On the next journey, the SCR system runs a self-diagnostic check, and the warning goes out if the problem has cleared.
Fault confirmed during the permitted driving phase (between 1,100 km and 0 km / 685 miles and 0 miles):
Starting prevented:
Every time you switch on the ignition, the message "Emissions fault: Starting prevented" or "NO START IN" is displayed.
When an SCR fault is detected, contact a PEUGEOT dealer or qualified workshop. The system keeps the car compliant with emissions regulations, so the fault must be repaired professionally. Once the "Starting prevented" warning appears, you won't be able to start the car, and it needs urgent attention.
The power indicator on the electric Peugeot 208 shows how much energy the electric drivetrain is using or recovering. It helps you understand the car's energy consumption and charging and drive more efficiently. Its zones are:
CHARGE:
ECO:
POWER:
NEUTRAL:
The ECO zone helps you save energy, CHARGE shows the battery being recharged efficiently, and POWER shows consumption rising under hard acceleration. Adjusting your driving based on this information helps you get the most range from the car.
This indicator shows the traction battery's current charge level and remaining range, giving you the information you need to manage energy and plan charging.
Charge level and remaining range shown continuously:
When you start the car, the traction battery's charge level and remaining driving range are shown on the instrument panel at all times.
Waking the gauge with the ignition off:
With the ignition off, opening the driver's door activates the gauge.
As the energy level drops, two warning levels appear on the instrument panel:
a. Reserve level:
When the traction battery charge is low, the lamp comes on steadily and the gauge shows the red zone, with an audible signal.
The remaining range is shown on the instrument panel.
You are advised to charge the car as soon as possible.
b. Critical level:
When the traction battery reaches a critical level, the reserve warning lamp stays on with an audible signal.
The car must now be charged.
The remaining range is no longer calculated and drive power is gradually reduced.
Heating and air conditioning are switched off to reduce energy consumption.
The low and critical level warnings make sure you're never caught out by running out of energy, so you can plan your driving and charging accordingly.
This gauge shows how much electrical energy the cabin's thermal comfort equipment, mainly the heating and air conditioning, is drawing from the traction battery, so you can keep an eye on their consumption.
Display and modes:
Using the heating and air conditioning:
Energy consumption and range:
Smell on first use:
If you haven't used the heating for a long time, you may notice a slight smell for the first few minutes.
