How to Check Peugeot 408 Warning Lights and Displays

The 408 uses Peugeot's latest i-Cockpit layout: a compact steering wheel, a digital instrument panel that sits above it and a 10-inch touchscreen with i-Toggle shortcuts. This guide helps you get the most from it, from reading the trip computer and resetting the counters to using the Energy app and the plug-in hybrid's remote functions.

It's based on the official Peugeot 408 owner's handbook for the 408 fastback (2022 on).

Trip Computer

Instrument Panel

On the 408 you can display different tabs on the instrument panel, cycling through them by pressing the button on the end of the wiper control stalk. The instrument panel shows a range of operating and performance information.

Current Information Tab

This tab shows:

Current consumption (petrol): the car's instantaneous fuel consumption, giving you a sense of fuel efficiency.

Stop & Start time counter (petrol): how long Stop & Start has been active, helping you see how much it contributes to saving fuel.

Percentage of distance driven in fully electric mode (plug-in hybrid): the share of driving done in fully electric mode on plug-in hybrids.

Odometer (plug-in hybrid): the total distance covered by the plug-in hybrid.

Trip "1" and "2" Tabs

These tabs give more detail about your journeys:

Average speed: the car's average speed during the trip.

Average fuel consumption: average fuel consumption over the trip, giving you an idea of efficiency.

Distance travelled: the total distance covered during the trip.

Resetting the Trip Counters

Reset the Peugeot 408 Trip Counters

Resetting your trip data on the 408 is simple. With the trip you want displayed on the instrument panel, press and hold the button on the end of the wiper control stalk for more than 2 seconds. It's useful when starting a new journey or when you want to monitor the car's performance over a set period.

Trips "1" and "2" work independently and are reset the same way, so you can record data for two different journeys or periods and keep them separate.

Instrument Panel Definitions

Here are some of the most common values on the 408's instrument panel and what they mean:

Range

This shows how far you can drive on the fuel left in the tank, calculated from the average fuel consumption over the last few kilometres (or miles). Changes in your driving style or road conditions can change the figure. When the range drops below 30 km (or the equivalent in miles), dashes appear on the instrument panel. After adding at least 5 litres of fuel, the range is recalculated and shown once it exceeds 100 km. Dashes instead of figures can indicate a fault, in which case you should contact a PEUGEOT dealer or qualified workshop.

Current Consumption

Shows the car's fuel consumption over the last few seconds, displayed only at speeds above 30 km/h, so you can monitor your instantaneous consumption.

Average Consumption

Calculated since the trip computer was last reset, it shows the car's fuel efficiency over a longer period.

Average Speed

The car's average speed since the trip computer was last reset.

Distance Travelled

The total distance covered since the trip computer was last reset.

Stop & Start Time Counter

If your car has Stop & Start, this counter adds up the total time spent in STOP mode during the journey. It resets automatically every time you switch on the ignition.

Energy Application

Peugeot 408 Energy Application Features

The 408 plug-in hybrid offers advanced features for managing and optimising energy. The Energy application brings them together in one place and helps you understand how the car uses energy. Its key features:

Energy Flow

Real-time display: shows the plug-in hybrid system working in real time, including the active driving mode, the petrol engine, the electric motor and the traction battery charge level.

Energy Flow Colour Codes

Blue: 100% electric energy.

White: energy from the petrol engine.

Green: energy recovery.

Statistics

Average electricity and fuel consumption statistics: shows average electricity consumption (kWh/100 km) and average fuel consumption (l/100 km) for the current journey and past values. Energy consumption appears as two graphs: energy drawn directly from the traction battery (blue) and energy generated during deceleration and braking (green). Average fuel consumption is shown in orange.

Charging

Deferred charging: set up a deferred charging programme for the traction battery.

e-SAVE

Energy reserve function: e-SAVE lets you keep the traction battery's electrical energy for later, which is especially useful for driving in town or in zones reserved for electric vehicles.

Reserve options: once the function is active, choose the electric range to keep in reserve (10 km, 20 km or the full range, shown as MAX). Activation is confirmed by an indicator lamp in the instrument panel and the reserved energy shown in miles or km.

Using the reserve: to use the energy reserve, select Electric mode with the drive mode selector. If the distance you request is more than is available, the petrol engine starts recharging the traction battery up to the requested threshold, which can lead to higher fuel consumption.

Make It a Habit

• Reset a trip counter at each fill-up or charge to track your real-world economy
• Customise the instrument panel display so the information you use most is always visible
• Keep the touchscreen and its software up to date. Our Peugeot software update guide explains how
• Don't adjust settings while you're driving: pull over first, or ask a passenger to do it
