3Heated seats



The function is active only with the engine
running and when the outside temperature is
below 20°C.
►
Press the button corresponding to the seat.
►


Each press changes the heating level; the
corresponding number of indicator lamps come
on.
►


T
o switch off the heating, press the button
until all of the indicator lamps are off.
The system status is memorised when the
ignition is switched off.
Do not use the function when the seat
is not occupied.
Reduce the heating intensity as soon as
possible.
When the seat and passenger compartment
have reached a satisfactory temperature,
switch the function off; reducing electrical
consumption in turn decreases energy
consumption.
Prolonged use of heated seats is not
recommended for people with sensitive
skin.
There is a risk of burns for people whose
perception of heat is impaired (e.g.
illness,
taking medication).
To keep the heated pad intact and to prevent
a short circuit:
–

Do not place heavy or sharp objects on the
seat.
–


Do not kneel or stand on the seat.
–


Do not spill liquids onto the seat.
–


Never use the heating function if the seat
is damp.

filter is in good condition and have the filter
elements replaced regularly

.
We recommend using a composite passenger
compartment filter. Its specific active additive
helps protect against polluting gases and bad
smells.
►

T

o ensure correct operation of the
air conditioning system, have it checked
according to the recommendations in the
Manufacturer’s service schedule.
Stop & Start
The heating and air conditioning systems
only operate when the engine is running.
Temporarily deactivate the Stop & Start
system to maintain a comfortable temperature
in the passenger compartment.
For more information on the Stop &
Start
system, refer to the corresponding
section.
