How to Check Peugeot 508 Warning Lights and Displays

In the 508, the instrument panel and the 10-inch touchscreen work together. The trip computer data sits in front of you, while apps such as Energy live on the central screen. This guide explains how to check your trip data, what each reading means, and how to use the touchscreen apps and remote functions.

It's based on the official Peugeot 508 owner's handbook for the second-generation 508 Fastback and SW (2018 on).

Trip Computer

The 508's trip computer shows key information about your current journey. It displays data such as fuel consumption, average speed and distance travelled in real time, helping you make better-informed decisions on the road.

Trip Computer Features

The trip computer works in two main modes on the instrument panel:

• "Personal" display mode: when selected, the trip computer data is displayed permanently on the instrument panel, so you always have up-to-date journey data.
• Other display modes: press the end of the wiper control stalk and the trip computer data appears on screen for a set time, so you can quickly check what you need.

Displaying the Different Tabs

Press the button on the end of the wiper control stalk to cycle through the following tabs:

Current Information

• Driving range (petrol or diesel).
• Current consumption (petrol or diesel).
• Stop & Start time counter (petrol or diesel).
• Percentage of distance driven in fully electric mode (plug-in hybrid).

Trip "1" and "2"

Pressing the end of the wiper stalk once and then twice opens these screens in turn. They show:

• Average speed.
• Average fuel consumption.
• Distance travelled.

Average speed and fuel consumption help you understand your fuel economy and adjust your driving if needed. For plug-in hybrid owners, tracking the share of driving in fully electric mode helps you make the most of the car's electric potential.

Resetting the Peugeot 508 Trip Counters

Resetting the trip counters clears the data from previous journeys so you can start a new one from zero. It's especially useful after long journeys or for comparing different driving conditions.

Reset the Counters

To reset the counters:

1. Display the trip you want on the instrument panel.
2. Press and hold the button on the end of the wiper control stalk for more than 2 seconds.
3. This works for both trip "1" and trip "2". The two counters are independent and are reset the same way.

Using the Counters Independently

Trips "1" and "2" are used independently, so you can track data separately for different journeys or driving conditions. For example, you might use trip "1" for daily driving in town and trip "2" for weekend trips.

Benefits

• Data tracking: track specific data for different journeys and driving conditions.
• Performance analysis: see how different driving modes and conditions affect fuel consumption and average speed.
• Personalised driving data: build data sets that match how you use the car.

Peugeot 508 Trip Computer Definitions

Range

Definition: the estimated distance the car can cover on the fuel left in the tank, based on the average consumption over the last few kilometres (or miles). It updates when your current consumption changes significantly with your driving style or road conditions. When the range drops below 30 km, dashes appear on the display. After adding at least 5 litres of fuel, it is recalculated and shown on the instrument panel once it exceeds 100 km. If dashes appear instead of figures while driving, there is a fault and you should consult a PEUGEOT dealer or qualified workshop.

Current Consumption

Definition: the car's fuel consumption over the last few seconds. It is shown only when the car is travelling above 30 km/h and updates continuously with the driving conditions.

Average Consumption

Definition: the car's average fuel consumption since the trip computer was last reset, showing how economically you've driven over the journey.

Average Speed

Definition: the average speed since the trip computer was last reset, over a particular journey or period.

Distance Travelled

Definition: the total distance covered since the trip computer was last reset.

Stop & Start Time Counter

Definition: if the car has Stop & Start, this counter adds up the total time spent in STOP mode during the journey, covering the periods when the car is stopped in traffic and the engine switches off and restarts automatically. It resets automatically every time you switch on the ignition.

10-Inch Touchscreen

At the centre of the 508's cabin, the 10-inch touchscreen gives you a wide range of functions. It doesn't just show the car's basic information; it also gives easy access to a series of key controls and features, making driving richer and safer.
