PROGRAMMABLE HEATING *
With the engine off, programmable
heating preheats the coolant circuit
in order to optimise the engine op-
erating temperature prior to starting.
The programmable heating sys-
tem can be started immediately or
delayed thanks to its programming
function. With the engine idle or the vehicle
stationary, it is normal to hear a
high-pitched whistling noise and
to notice some smoke/emissions. Digital programmer
The heating system’s programmer is
located on the left-hand side of the
dashboard.
1. Time or remaining functioning
time.
2. Increase (time).
3. Select programme.
4. Programme number selected.
5. Immediate start-up of heating.
6. Time adjustment and reading

Screenwash and headlamp

F l u i d s p e c i fi c a t i o n
For optimum cleaning and to avoid
f r e e z i n g , t h i s fl u i d m u s t n o t b e
topped up or replaced with water.
Reservoir capacities:
-
screenwash: approximately 3.5 litres,
- screenwash and headlamp wash: approximately 6.15 litres. Diesel additive level (Diesel
engine with particle emission
filter)
A low additive level is indicated by
lighting of the service warning light,
accompanied by an audible warning
and a message on the multifunction
display.
Topping up
This additive must be topped up by
a CITROËN dealer without delay.
Used products
Avoid prolonged contact of
u s e d o i l o r fl u i d s w i t h t h e
skin.
M o s t o f t h e s e fl u i d s a r e h a r m f u l t o

Empty used oil into the contain-
ers provided for this purpose in the
CITROËN network.

with headlamp washers, the
m i n i m u m l e v e l o f t h i s fl u i d i s
indicated by an audible signal
and a message on the multifunction
display.
Top up the level when you stop the
vehicle.
Coolant level
Draining the circuit
The coolant does not have to be
changed.
F l u i d s p e c i fi c a t i o n
The coolant must conform to the
manufacturer's recommendations. The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the tem-
perature of the coolant is regulated
by the fan. This can operate with the
ignition off.
O n v e h i c l e s w h i c h a r e fi t t e d w i t h
a p a r t i c l e e m i s s i o n fi l t e r , t h e f a n
may operate after the vehicle has
been switched off, even if the en-
gine is cold.
In addition, as the cooling system is
pressurised, wait at least one hour
after switching off the engine before
carrying out any work.
To avoid any risk of scalding, unscrew
the cap by two turns to allow the pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.
