Safety -> Engine brake reduction indicator lamp for Your Peugeot Ion 4 Door First Generation (2010-2020)

Safety  
Engine brake reduction indicator lamp  
We therefore recommend that you anticipate  
your braking as much as possible: use the  
brake pedal to slow down or stop the vehicle.  
The braking power is never reduced  
while the indicator lamp is flashing.  
Your vehicle is equipped with a system for the  
recovery of energy during deceleration which  
uses the engine brake.  
It recovers into the traction battery some of the  
energy generated when the vehicle slows down  
(e.g. on a long descent) to improve the range  
of the battery and so the distance that can be  
travelled between charges.  
When the traction battery has been charged  
fully and for the first few miles (or kilometres) of  
use of the vehicle, the engine brake is reduced  
temporarily.  
This indicator lamp flashes on the  
instrument panel, inviting you to  
adapt your driving accordingly.
