MONITORING
Warning lamps
When the engine is running or the vehicle is
being driven, the switching on of one of the fol-
lowing warning lamps indicates a fault which
requires action on the part of the driver. Any fault resulting in the switching on of a warning lamp must be investigated
further by reading the associated message on the multifunction screen.
If you encounter any problems, do not hesitate to contact a CITROËN dealer.

Warning lamp is on Cause Action/Observations

STOP fi xed, associated
with another
warning lamp,
accompanied by
an audible signal and a message on the screen.
It is associated with the braking system, the power steering,
the engine oil pressure or the
engine coolant temperature. Stop as soon as it is safe to do so.
Park, switch off the ignition and call a CITROËN
dealer.

Service temporarily,
accompanied
by an audible signal and a
message on the multifunction screen. A minor fault has occurred
for which there is no specifi c
warning lamp. Identify the fault by reading the message shown
on the screen, such as, for example:
- engine oil level,
- screenwash level,
- remote control battery,
- state of the bulbs,
- saturation of the particle emission fi lter (Die
sel).
For any other faults, contact a CITROËN dealer.
fi xed, accompanied
by an audible signal
and a message on the multifunction screen. A major fault has occurred
for which there is no specifi c
warning lamp. Identify the fault by reading the message shown
on the screen and contact a CITROËN dealer.


Braking fi xed, associated
with the STOP warning lamp. The braking system fl uid
level is too low. You must stop as soon as it is safe to do so.
Top up with brake fl uid recommended by CITROËN.
If the problem persists, have the system checked
by a CITROËN dealer.
+ fi xed, associated
with the STOP and
ABS warning lamp. The electronic brake force
distribution (EBFD) system
has a fault.
You must stop as soon as it is safe to do so.
Have it checked by a CITROËN dealer.

MONITORING

Warning lamp is on Cause Action/Observations

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.


Engine oil
pressure fi xed. There is a fault with the
engine lubrication system. Stop as soon it is safe to do so.
Park, switch off the ignition and contact a
CITROËN dealer.

Battery
charge fi xed. The battery charging circuit
has a fault (dirty or loose
terminals, slack or cut alter-
nator belt, ...). The warning lamp should go off when the engine
is started.
If it does not switch off, contact a CITROËN deale
r.

Door(s) open fi xed if the
speed is
below 6 mph (10 km/h).
A door or the boot is still open. Close the door or boot.
fi xed and
accompanied
by an audible signal if the speed is
above 6 mph (10 km/h).

CHECKS
CHECKING LEVELS Brake fluid level
Oil level The reading will only be correct
if the vehicle is on level ground
and the engine has been off for
more than 15 minutes.
The check is carried out either when
the ignition is switched on using the oil
level indicator on the instrument panel,
or using the dipstick. The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.
Changing the fl uid
Refer to the Maintenance and Warranty
Guide for details of the interval for this
operation.
Coolant level The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the
temperature of the coolant is regulated
by the fan. This can operate with the
ignition off.

On vehicles which are fi tted with a par-
ticle emission fi lter, the fan may oper-
ate after the vehicle has been switched
off, 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. Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be topped
up or replaced with water.
Engine oil change
Refer to the Maintenance and Warranty
Guide for details of the interval for this
operation.
In order to maintain the reliability of the
engine and emission control system,
the use of additives in the engine oil is
prohibited.
Oil grade
The oil must be suitable for your engine
and conform to the manufacturer's
recommendations. Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations and
meet the DOT4 standard.
Fluid specifi cation
The coolant must conform to the manu-
facturer's recommendations.
Changing the coolant
The coolant does not have to be
changed.
Screenwash fluid level
Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer.
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.
Top up the level when neces-
sary.
Take care when carrying out checks
under the bonnet as some parts of
the engine can be very hot (risk of
burns).

PRACTICAL INFORMATION
TOWING A TRAILER, A CARAVAN, ETC.
Your vehicle is primarily designed for
transporting people and luggage, but it
may also be used for towing a trailer. Driving advice
The maximum towed load on a long in-
cline depends on the gradient and the
ambient temperature.
In all cases, keep a check on the cool-
ant temperature.
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. Braking
Towing a trailer increases the braking
distance.
Tyres

 Check the tyre pressures of the
towing vehicle and of the trailer,
observing the recommended pres-
sures.
Lighting

 Check the electrical lighting and sig-
nalling on the trailer.
The rear parking sensors will be
deactivated automatically if a gen-
uine CITROËN towbar is used.
 If the warning lamp and the

STOP warning lamp come
on, stop the vehicle and
switch off the engine as
soon as possible.
Towbar suitable for the attachment of a
trailer or caravan with additional lighting
and signalling.
Distribution of loads

 Distribute the load in the trailer so
that the heaviest items are as close
as possible to the axle and the nose
weight approaches the maximum
permitted without exceeding it.
Air density decreases with altitude, thus
reducing engine performance. Above
1 000 metres, the maximum towed load
must be reduced by 10 % for every
1 000 metres of altitude.
Refer to the "Technical Data" section for
details of the weights and towed loads
which apply to your vehicle.
Driving with a trailer subjects the towing
vehicle to more signifi cant stress and
the driver must take particular care.
We recommend the use of genuine
CITROËN towbars and their har-
nesses that have been tested and
approved from the design stage
of your vehicle, and that the fi t-
ting of the towbar is entrusted to a
CITROËN dealer.
If the trailer is not fi tted by a
CITROËN dealer, it is imperative
that it is fi tted using the vehicle's
electrical pre-equipment, in accor-
dance with the manufacturer's in-
structions.
