ADDITIONAL HEATING  
Vehicles fitted with an HDi engine may be 
fitted with a heater. When the engine is at 
idle or the vehicle is stationary, it is normal 
to notice a high-pitched whistling noise and 
a slight emission of smoke and odour.

Coolant circuit heater 
  This is an additional and separate system 
which heats the Diesel engine cooling 
system to make starting easier. 
  It improves the demisting and defrosting 
performance.

 Ventilation 
  Have the heater checked at least 
once a year at the beginning of winter. 
Maintenance and repairs should only be 
carried out by a PEUGEOT dealer or 
a qualified workshop. Use recommended 
replacement parts only.  
 
 
Good practice
 
To avoid any risk of poisoning or 
asphyxiation, the heater must not be used, 
even for short periods, in an enclosed space 
such as a garage or workshop which is not 
fitted with an exhaust gas extraction system. 
  Do not park the vehicle on an inflammable 
surface (dry grass, dead leaves, paper…), 
there is a risk of fire. 
  The temperature near the heater must not 
exceed 120 °C. A temperature higher than 
this (for example in the case of painting in 
an oven) could damage the components of 
the electronic circuits. 
  The heater is supplied by the vehicle's fuel 
tank. Ensure that the low fuel warning lamp 
is not on.
