Lighting is associated
with another warning
lamp:
Service If this warning lamp
comes on, it indicates
the occurrence of a
problem in one of the
systems which does not have a spe-
c i fi c w a r n i n g l a m p .
In order to identify it, see the mes-
sage on the multifunction screen.
The warning lamp only comes on
temporarily in the case of the follow-
ing minor faults:
- incorrect closing of the doors, boot, rear screen and bonnet,
- fl a t r e m o t e c o n t r o l b a t t e r y ,
- low tyre pressure,
- the saturation of the particle e m i s s i o n fi l t e r ( D i e s e l ) .
In the case of major faults, the warn-
ing lamp remains on until the operating
f a u l t i s r e c t i fi e d , c o n t a c t a C I T R O Ë N
dealer as soon as possible. Braking
If this comes on, it indicates
the occurrence of a fault in
one of the braking systems:
- s i g n i fi c a n t d r o p i n t h e fl u i d l e v e l in the circuit,
- electronic brake force distribu- tion (EBFD) faulty (simultane-
ous lighting of the ABS warning
lamp),
stop the vehicle immediately and as
safely as possible.
Consult a CITROËN dealer.
Parking brake
When stationary, the perma-
nent lighting of this warning

With the engine running, and when
displayed at the same time as the
STOP warning lamp, it indicates that
t h e b r a k e fl u i d l e v e l i s t o o l o w . Electric parking brake fault
This warning lamp comes
on if there is a fault with the
electric parking brake.
Electric parking brake -
deactivation of automatic
functions This warning lamp comes
on if the "automatic lock-
ing" (upon switching off the
ignition) and the "automatic
unlocking" functions are de-
activated or faulty.
Dynamic stability control
(ESP/ASR) The ESP/ASR system is put
into service automatically
when the vehicle is started.
Unless the system has been deacti-
vated, if this warning lamp comes on
continuously, accompanied by a mes-
sage on the instrument panel screen,
switching on of the SERVICE warning
lamp and an audible signal, this indi-
cates the occurrence of a fault in the
ESP/ASR system.
Central alert
- punctured wheel,
- braking,
- coolant temperature,
stop the vehicle immediately and as
safely as possible.
Consult a CITROËN dealer.
Anti-lock braking system (ABS) If this comes on, it indicates
the occurrence of a fault in
the anti-lock braking sys-
tem.
However, this does not prevent op-
eration of the vehicle's servo assist-
ed braking. If this warning lamp comes on, stop
immediately and contact a CITROËN
dealer.
Consult a CITROËN dealer.

Engine autodiagnostics system If this comes on, it indicates
the occurrence of a fault in
the engine management
system.
I f i t fl a s h e s , i t i n d i c a t e s t h e o c c u r r e n c e o f
a fault in the emission control system.
Maximum coolant temperature If this comes on, it indicates
that the temperature in the
cooling system is too high.
Stop the vehicle immediately
and as safely as possible.
Check the coolant level.
If the level is low, contact a CITROËN
dealer.
Fuel low
If this comes on, it indicates
that the range remaining
i s a p p r o x i m a t e l y 3 0 m i l e s
(50 km).
It may be less than this in certain
driving conditions and depending on
the engine.

mately 71 litres. Battery charge
If this comes on, it indi-
cates the occurrence of a
fault in the battery charging
circuit (dirty or loose termi-
nals, slack or cut alternator
belt...).

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 right-hand side of the
dashboard.

Top up the level when you stop the
vehicle.
Coolant level
Coolant change
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
s h o u l d n e v e r e x c e e d i t .
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

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.

P R A C T I C A L I N F O R M A T I O N
TOWING A TRAILER, A CARAVAN, ETC.
Towbar suited to the attachment of a
trailer or caravan with additional sig-
nalling and lighting.
Your vehicle is primarily designed
for transporting people and luggage,
but it may also be used for towing a
trailer.
We recommend the use of genuine
CITROËN towbars and their har-
nesses that have been tested and
approved from the design stage
o f y o u r v e h i c l e , a n d t h a t t h e fi t -
ting of the towbar is entrusted to a
CITROËN dealer. I f t h e t r a i l e r i s n o t fi t t e d b y
a CITROËN dealer, it is
i m p e r a t i v e t h a t i t i s fi t t e d
using the electrical pre-equipment
installed at the rear of the vehicle,
in accordance with the manufactur-
er’s instructions.
Driving with a trailer subjects the
t o w i n g v e h i c l e t o m o r e s i g n i fi c a n t
stress and its driver must be par-
ticularly careful.
Driving advice
Distribution of loads
Distribute the load in the trailer
so that the heaviest items are as
c l o s e a s p o s s i b l e t o t h e a x l e a n d
the nose weight approaches the
m a x i m u m p e r m i t t e d w i t h o u t e x -
ceeding it.
Air density decreases with altitude,
thus reducing engine performance.
A b o v e 1 0 0 0 m e t r e s , t h e m a x i m u m
t o w i n g l o a d m u s t b e r e d u c e d b y 1 0 %
and so on for every 1 000 metres of
altitude.
Refer to the "Technical Data" section
for details of the weights and towing
loads which apply to your vehicle.
Side wind
Take into account the increased
sensitivity to side wind. Cooling
Towing a trailer on a slope increases
the temperature of the coolant.
As the fan is electrically controlled,
its cooling capacity is not dependent
on the engine speed.
To lower the engine speed, reduce
your speed.
T h e m a x i m u m t o w i n g l o a d o n a l o n g
slope depends on the gradient and
the ambient temperature.
In all cases, pay attention to the
coolant temperature.
If the warning lamp and
the STOP warning lamp
come on, stop the vehicle
and switch off the engine
as soon as possible.
Braking
Towing a trailer increases the brak-
ing distance.
Tyres
Check the tyre pressures of the
towing vehicle and of the trailer,
observing the recommended
pressures.
Lighting
Check the electrical signalling on
the trailer.
The rear parking assistance will
be deactivated automatically if an
original CITROËN towbar is used.
