Towing a trailer

Cooling:
towing a trailer on a slope
increases the coolant temperature.
As the fan is electrically controlled, its
cooling capacity is not dependent on the
engine speed.
On the contrary, use a high gear to lower the
engine speed and reduce your speed.
In all cases, pay attention to the coolant
temperature.
Tyres:
check the tyre pressures of the
towing vehicle (see the "Identification
markings" section of chapter 9) and of
the trailer, observing the recommended
pressures.
We recommend the use of original
CITROËN towbars and their harnesses,
which have been tested and approved from
the design stage of your vehicle and that
the fitting of this equipment is entrusted to a
CITROËN dealer.
If this equipment is not fitted by a CITROËN
dealer, it is imperative that it is fitted using
the electrical pre-equipment installed at the
rear of the vehicle and in accordance with
the manufacturer's instructions.


Good practice

In certain cases of particularly arduous
use (towing the maximum load up a steep
slope in high temperatures), the engine
automatically limits its power. In this
case, the automatic cutting off of the air
conditioning allows the engine power to be
recovered.
If the coolant temperature
warning lamp comes on, stop the
vehicle and switch off the engine
as soon as possible.
See the "Levels" section of chapter 7.
Brakes:
towing increases the braking
distance. Drive at a moderate speed,
change down early and brake gradually.

Side wind:
sensitivity to side wind is
increased. Drive smoothly and at a
moderate speed.

ABS:
the system only controls the vehicle,
not the trailer.

Rear parking sensors:
the system does not
operate while the vehicle is towing.

Levels
LEVELS
These regular maintenance operations
will keep your vehicle in good running
order. Ask for advice at a CITROËN dealer
or consult the servicing booklet enclosed in
the handbook pack. To maintain the reliability of engines and
emission control systems, the use of
additives in engine oil is prohibited.

Changing the brake fluid

The brake fluid must be changed at
the intervals stated, according to the
manufacturer's servicing schedule.
Use fluids recommended by the
manufacturer, which fulfil DOT4 standards.
The level must be between the MIN
and
MAX
marks on the reservoir.
If fluid has to be added frequently, this
indicates a failure which must be checked by
a CITROËN dealer as soon as possible. If you have to remove/refit the engine
style cover, handle it with care to avoid
damaging the fixing clips.

Dipstick
There are two marks on
the dipstick:

Oil change

It is imperative that this is carried out at the
intervals specified and the viscosity grade of
the oil selected must fulfil the requirements
in accordance with the manufacturer's
servicing schedule. Ask for advice at at
CITROËN dealer.
Remove the dipstick before filling.
Check the level after filling (never exceed
the maximum mark).
Screw the cap back onto the sump before
closing the bonnet.

Viscosity selection

In all cases, the oil selected must meet the
manufacturer's requirements.
Warning lamps


Checking by means of the warning
lamps on the instrument panel is
described in chapter 2, refer to the
"Instruments and controls" section.

A
= maximum
If you fill past this mark,
contact a CITROËN dealer.

B
= minimum
Never allow the level to fall
below this mark.
Oil level
Check the level regularly and top up
between changes. The maximum
consumption is 0.5 litre per 600 miles
(1 000 km). Check the level with the vehicle
level, engine cold, using the dipstick.

Levels


Cooling system

Only use the fluid recommended by the
manufacturer. Otherwise, you risk seriously
damaging your engine. When the engine
is warm, the temperature of the coolant is
controlled by the engine fan. As this fan can
operate with the ignition key removed and
because the cooling system is pressurised,
wait for at least one hour after the engine
has stopped before carrying out any work.
Slacken the cap by 1/4 of a turn to release
the pressure to prevent any risk of scalding.
When the pressure has dropped, remove the
cap and top up the level with coolant.
If fluid has to be added frequently, this
indicates a failure which must be checked by
a CITROËN dealer as soon as possible.
Power steering fluid level

The vehicle must be parked on level ground with
the engine cold. Unscrew the cap integrated with
the gauge and check the level which must be
between the MIN
and MAX
marks.

Used oil

Avoid prolonged contact of used oil with the
skin.
Brake fluid is harmful to health and very
corrosive.
Do not dispose of used oil, brake fluid or
coolant into drains or into the ground but
into the containers dedicated to this use
at CITROËN dealerships (France) or to an
authorised waste disposal site.


Topping up

The level must be between the MIN
and
MAX
marks on the expansion bottle. If
more than 1 litre of fluid is required to top
up the level, have the system checked by a
CITROËN dealer.
Windscreen wash and headlamp washlevel

For best quality cleaning and to prevent
freezing, this fluid must not be topped up or
replaced with plain water.
Capacity of the reservoir: approximately
5.5 litres.

Air filter and passenger compartmentfilter

A clogged passenger compartment fi lter may
reduce the performance of the air conditioning
system and generate undesirable odours. The
replacement intervals for these components
are indicated in the servicing booklet.
Depending on the environment (dusty
atmosphere...) and the use of the vehicle
(urban driving...), change them twice as often
if necessary, refer to the "Under the bonnet"
section of chapter 7.
Manual gearbox

Have the level checked in accordance with
the manufacturer's servicing schedule.
To check the main levels and certain
components, in accordance with the
manufacturer's servicing schedule, refer to
the pages of the servicing booklet which
correspond to your vehicle's engine.
Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of units as
important as the braking system, CITROËN
selects and offers specific products.
In order to avoid damaging the electrical
units, high pressure washing to clean the
engine compartment is strictly prohibited.
Parking brake
Where the parking brake travel is too great
or there is a reduction in the performance
of the system, the parking brake should be
adjusted, even between services.
Have the system checked by a CITROËN
dealer. Bleeding the water contained in the Diesel filter

If this warning lamp comes on,
bleed the filter, otherwise bleed
regularly each time the engine oil
is changed.
To drain the water out, unscrew the bleed
screw or the water in Diesel sensor, located
at the base of the filter. Leave open until
all of the water has been drained out. Then
tighten the bleed screw or the water sensor.
HDi engines use advanced technology. All
work requires a special qualification which is
guaranteed by a CITROËN dealer.
Battery

At the start of winter, have your battery
checked by a CITROËN dealer.

Brake pads

Brake pad wear depends on the style of
driving, in particular for vehicles which are
used in town, over short distances. It may
be necessary to check the thickness of the
pads, even between services.
Unless there is a leak on the system, a drop
in the brake fluid level indicates that the
brake pads are worn.


Brake disc/drum wear status

For any information relating to checking
the brake disc/drum wear status, contact a
CITROËN dealer.
Oil filter

Change the filter regularly, in accordance
with the servicing schedule.






The presence of this label, in particular
with the Stop & Start system, indicates the
use of a specific 12 V lead-acid battery
with special technology and specification.
The involvement of a CITROËN dealer
or a qualified workshop is essential when
replacing or disconnecting the battery.

Checks

Particle filter system (Diesel)

An addition to the catalytic converter, this
filter makes an active contribution to the
preservation of air quality by the retaining
of the unburnt pollutant particles. Black
exhaust fumes are thus no longer emitted.
This filter, fitted to the exhaust system,
accumulates particles of soot. The engine
control unit manages the automatic
periodic elimination of the soot particles
(regeneration).
The regeneration procedure is invoked
according to the quantity of particles
accumulated and the driving conditions of
the vehicle. During this phase, you may
notice some unusual phenomena - increased
idling speed, cooling fan running, increase in
smoke and higher exhaust gas temperature -
which does not affect the operation of the
vehicle or the environment. After prolonged idling or driving at very low
speeds, you may occasionally notice water
vapour being emitted from the exhaust when
accelerating. This is of no consequence
to the running of the vehicle or to the
environment.
Because of the higher exhaust gas
temperature resulting from the normal
operation of the particle filter, it is
recommended that you do not park the
vehicle over inflammable materials (grass,
dry leaves, pine needles, ...) so as to avoid
any risk of fire.
Saturation / Regeneration

Operating fault
If this alert persists, do not ignore the
warning; it indicates that a fault has occurred
in the exhaust / particle filter system.
Have it checked by a CITROËN dealer.
If there is risk of blockage of the
filter, this warning lamp comes on
in the instrument panel.
This alert tells you that the particle filter
is starting to fill up (in conditions of urban
driving of exceptionally long duration: low
speeds, traffic jams etc.)
To regenerate the filter, it is advised to drive
as soon as possible, when traffic conditions
and the law permit, at a speed of at least
40 mph (around 60 km/h), with an engine
speed above 2 000 rpm for about fifteen
minutes (until the warning lamp and/or the
message disappears).
If possible, avoid switching off the engine
before the end of regeneration of the
filter; repeated interruptions could cause
premature deterioration of the engine oil. It
is not recommended to end regeneration of
the filter with the vehicle stationary.

Fuel


Low fuel level

When the fuel tank level E
(Empty) is reached, this warning
lamp comes on. At this moment,
you have enough fuel left to
drive approximately 30 miles (50 km)
,
depending on the driving conditions, the
engine and the profile of the road. Fill up
without delay to avoid running out of fuel. The fuel tank must be filled with the engine
off.


- Open the fuel filler flap.

- Support the cap with one hand.

- With the other hand, insert the key, then
turn it anticlockwise.

- Remove the cap and hook it onto the
clip located on the inside of the flap.
A label affixed to the inside of the flap
reminds you of the type of fuel to be used.
When filling the fuel tank, do not continue
after the 3rd cut-off of the nozzle. This could
cause malfunctions.
The capacity of the fuel tank is
approximately 90
litres.


- After filling the fuel tank, lock the cap
and close the flap.

FUEL SYSTEM CUT-OFF

In the event of a serious collision, a device
automatically cuts off the fuel supply
to the engine and the vehicle's electrical
supply.
FILLING WITH FUEL

Fuel tanks of different capacities,
60 and 125 litres, may be fitted. Check that there is no smell or leak of fuel
outside the vehicle.
Restore the supply by pressing:


-
the fi rst button,
located below the steering wheel.


- the second button, located in the
battery compartment, under the front
passenger's floor.


In low temperatures
In mountainous and/or cold areas, it is
advisable to use a "winter" type fuel suited
to low or minus temperatures.






With Stop & Start, never refuel with
the system in STOP mode; you must
switch off the ignition with the key.

Charging the battery using a charger



- disconnect the battery located in the
front left floor,

- follow the instructions for use given by
the battery charger manufacturer,

- reconnect starting with the negative (-)
terminal,

- check that the terminals and connectors
are clean. If they are covered with
sulphate (white or greenish deposit),
disconnect them and clean them.
The charging operation must be carried
out in a ventilated area away from naked
flames or any possible sources of sparks to
eliminate the risk of explosion and fire.
Do not attempt to charge a frozen battery: it
must first be thawed to eliminate the risks of
explosion. If the battery has frozen, before
charging it have it checked by a specialist
who will check that the internal components
have not been damaged and that the
container is not cracked, which could mean
that there is a risk of a leak of toxic and
corrosive acid.
Proceed with a slow charge charge at low
current for a maximum pf about 24 hours to
avoid damaging the battery.
