Cause



Action / Observations






Low fuel
level


fi xed. When it fi rst comes on there
remains approximately
5 litres of

This warning lamp wil come on every time
the ignition is switched on, until a suffi cient
addition of fuel is made.
Fuel tank capacity: 71 litres.
Never continue to drive until you run out
of fuel, this could damage the emission
control and injection systems.




Maximum
coolant
temperature


fi xed red. The temperature of the
cooling system is too high. Stop as soon as it is safe to do so.
Wait until the engine has cooled down
before topping up the level, if necessary.
If the problem persists, contact a
CITROËN dealer or qualifi ed workshop.




Battery

MONITORING















Engine oil temperature gauge

Under normal operating conditions,
the bars should be within section 1
.
In severe operating conditions, the
bars may extend into section 2
.
In this event, slow down, and if neces-
sary, stop the engine and check the
levels (see corresponding section).


Coolant temperature gauge

Under normal operating conditions,
the bars should be within section 1
.
In severe operating conditions, the
bars may extend into section 2
, the
engine coolant temperature warning
lamp A
and the STOP
warning lamp
come on, stop as soon as it is safe
to do so
. Switch off the ignition. The
cooling fan may continue to oper-
ate for a certain time
.
Contact a CITROËN dealer or a
qualifi ed workshop.
If the SERVICE
warning lamp comes
on, check the levels (see corre-
sponding chapter). On horizontal ground, illumination of
the fuel low warning lamp indicates
that you are at the reserve level.
An alert message is displayed in the
instrument panel.

COMFORT
PROGRAMMABLE HEATING

The programmable heating operates
independently of the engine.
When the engine is off, it pre-heats
the coolant circuit in order to benefi t
from an optimum engine operating
temperature from the time the en-
gine is switched on.
The programmable heating system
is switched on using the long range
remote control. Activation can be im-
mediate or deferred by means of a
programming function.

Programming remote control

The heating system programming
remote control consists of the fol-
lowing buttons and displays:


1.
Scrolling functions menu but-
tons.

2.
Function indicators: clock, tem-
perature, operating time, pro-
grammed time, heater operation,
heating management symbols.

3.
Digital displays: time, tempera-
ture, duration of operation, pro-
grammed time or level of heating.

4.
Off button.

5.
On button.



Displays on the remote
control screen

Press the buttons 1
in succession to
display the functions.
The fi rst press of the left-hand or
right-hand button displays the time.
Next, the left-hand button permits
access to the programming time then
to the level of heating (C1 to C5).
The right-hand button permits ac-
cess to the passenger compartment
temperature then to the duration of
operation of the heater if it is to be
switched on immediately.

If a malfunction of the program-
mable heating system occurs,
contact a CITROËN dealer
or a

qualifi ed workshop

.




Displaying the functions


The passenger compartment tem-
perature information is only avail-
able when the engine is off.

Diesel additive level
(Diesel engine with particle
emission filter)

Topping up
This additive must be topped up by
a CITROËN dealer or a qualifi ed
workshop without delay.









Used products

Avoid prolonged contact of
used oil or fl uids with the skin.
Most of these fl uids are harmful to
health or indeed very corrosive.
Do not discard used oil or fl u-
ids into sewers or onto the
ground.
Take used oil to a CITROËN dealer
or a qualifi ed workshop (France) or
to an authorised waste disposal
site. The additive reservoir
low level is indicated
by fi xed illumination
of this warning lamp,
accompanied by an audible warning
and a message in the multifunction
screen.










Coolant level


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.

Changing the coolant
The coolant does not have to be
changed.

Fluid specifi cation
The coolant must conform to the
manufacturer's recommendations.






For vehicles fi tted with a particle
emissions fi lter, the cooling fan may
continue to run after stopping the
vehicle, even if the engine 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.






















Screenwash and headlamp
wash fluid


In the case of vehicles fi tted
with headlamp washers, the
low fl uid level is indicated
by an audible signal and a
message in the screen.
Top up the reservoir when you next
stop the vehicle.

Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be
topped up with or replaced with plain
water.



Reservoir capacity (depending on
version).


- screenwash fl uid: approximately
3.5 litres,

- screenwash and headlamp wash
fl uid: approximately 6.15 litres.
