Peugeot 508 Warning Lamps: Blue and Green Warnings
Peugeot 508 indicator lamps explained: Stop & Start, plug-in hybrid Ready, lane positioning, Night Vision, lights, foot on brake and e-SAVE.
Not every lamp on your Peugeot 508's dashboard is a warning. Green, blue and white/grey symbols mostly confirm that something is switched on: your lights, a driver assistance system or a hybrid feature. Knowing them means you won't worry over a symbol that's simply doing its job. This guide covers the indicator lamps on the second-generation 508 Fastback and SW (2018 on), with the official Peugeot 508 owner's handbook as our reference.
Many 508s are plug-in hybrids, so alongside the usual engine warnings you'll find a few that only appear on the Hybrid and PSE versions.

Green Indicator Lamps
Green means "on and working". None of these lamps signal a fault. They confirm that something you've switched on, or the car has switched on automatically, is active.
Stop & Start
- Steady: the car has stopped and Stop & Start has switched the engine off to save fuel. It restarts as soon as you release the brake (automatic) or press the clutch (manual)
- Flashing briefly: the engine can't stop this time, or it has restarted automatically, for example to keep the cabin warm or the battery charged
Vehicle Ready to Drive (Plug-in Hybrid)
With no engine noise, it's not always obvious that a plug-in hybrid or electric Peugeot is on. This lamp, with a chime, confirms the car is ready to drive (and on electric versions that heating and cooling are available). It goes out above about 3 mph (5 km/h), comes back when you stop, and goes off when you switch off and get out.
Lane Positioning Assist
This lamp shows lane positioning assist is active and all its conditions are met. It keeps the car at your chosen position in the lane, usually alongside adaptive cruise control. Keep your hands on the wheel: it's an aid, not autopilot.
Automatic Wiping
Automatic wiping is on. A rain sensor behind the windscreen adjusts the wiper speed to the amount of rain. Switch it off before you go through a car wash.
Night Vision
- Grey: Night Vision is on but not available at the moment
- Steady: the infrared camera is working and can highlight pedestrians and animals beyond the reach of your headlights
Direction Indicators
The green arrows flash, with a ticking sound, when you indicate. If an arrow flashes noticeably faster than usual, a bulb or LED on that side has probably failed. Check it, because a faulty indicator is an MOT failure in the UK.
Sidelamps
Your sidelamps (sidelights or parking lights) are on. They're for parking in poorly lit areas or as a backup. Don't drive at night with only your sidelights on; use dipped beam.
Dipped Beam Headlamps
Dipped beam (low beam) is on. This is the normal setting for driving at night and in poor visibility. On cars with automatic lighting, it switches on by itself when it gets dark.
PEUGEOT Matrix LED Technology 2.0
- Grey: the adaptive Matrix LED headlamps are switched on but not all operating conditions are met yet (for example, the car is in a lit area or going too slowly)
- Coloured/steady: the system is working. It keeps main beam on while shading out other road users
Blue Indicator Lamps
Blue is reserved for the main beam (high beam) indicator. If you can see it, so can oncoming drivers, so dip your lights for other road users.
Main Beam Headlamps
The blue lamp shows your main beam (high beam) is on. Dip it for oncoming traffic and when you're following another car, so you don't dazzle the driver.
Black/White (Grey) Indicator Lamps
On digital instrument panels, white or grey symbols show the status of driver assistance systems: a grey lamp usually means "switched on but not available right now", while a white or coloured one means "working".
Foot on the Brake
This lamp is a reminder to press the brake pedal. You'll typically see it when you try to move the gear selector out of P or N, or release the parking brake, without your foot on the brake. Press the brake firmly and try again.
e-SAVE Function (Plug-in Hybrid)
On plug-in hybrids, e-SAVE holds back part of the battery's charge for later. With the lamp on, the display shows how much electric range is being saved. A typical use is to drive on petrol on the motorway and keep the battery for zero-emission driving in town or in a clean-air zone at the end of your trip.
A Quick Tip
If a symbol you don't recognise appears in red or orange, it's a warning rather than an indicator. Check the other guides in this series, or the handbook, before you assume it's harmless.
