2009 Citroen NEMO pressure

Towing a trailer
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 light comes on, stop the
vehicle and switch off the engine
as soon as possible.
See the "Levels" section of chapter 7.

Tyres: check the tyre pressures of the
towing vehicle (see the "Identification
features" section of chapter 7) and of
the trailer, observing the recommended
pressure.

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 assistance: the
assistance will be deactivated
automatically when an original CITROËN
towbar is used (see the "Rear parking
assistance" section of chapter 4).
Towbar
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 essential that it is fitted using
the electrical pre-equipment located at the
rear of the vehicle in accordance with the
manufacturer ’s instructions.
The operation of the sensors is deactivated
automatically when the pin of the trailer
cable is inserted in the towbar socket.
When the trailer cable pin is removed, the
sensors are re-activated.

Distribution of loads
Distribute the load in the trailer so that the
heaviest objects are as close as possible
to the axle and the nose weight is close to
the maximum authorised without, however,
exceeding it. The air density decreases with
altitude, so reducing the performance of
the engine. The maximum towed load must
be reduced by 10 % for each 1 000 metres
of altitude. Refer to the "Technical data"
chapter for details of the weights and towed
loads applicable to your vehicle and also to
the administrative documents
(V5 registration document, ...).

TROUBLESHOOTING
Changing a wheel
Refitting the wheel

6. Put the trim back in place, starting by
placing its notch facing the valve, and
press with the palm of your hand.

7. Stow the tools and the wheel.

8. Check the wheel inflation pressure
(see "Identification") and have the
balance checked. Refer to the "Identification features"
section of chapter 8 to locate the tyre
label.
Have the tightening of the bolts and the
pressure of the spare wheel checked by a
CITROËN dealer without delay.

1. Put the wheel in place using the centring
guide 2 to assist you.

2. Screw in the 3 bolts by hand and remove
the centring guide. Position the 4th bolt.

3. Pre-tighten using the wheelbrace 1 .

4. Fold the jack 4 and detach it.

5. Tighten the wheel bolts using the
wheelbrace. Also, have the original wheel repaired
and refitted by a CITROËN dealer as
soon as possible.

Changing a bulb
Front lamps
Open the bonnet. To access the bulbs, reach
behind the headlamp unit.
Remove the protective covers to gain
access to the bulbs.
Carry out the operations in reverse order to
refit each bulb.
CHANGING A BULB
Types of bulb
Various types of bulb are fitted on your
vehicle.
To remove them:

1. Type A
Entirely glass bulb: pull gently as it is fitted by pressure.

2. Type B
Bayonet bulb: press on the bulb then turn it anticlockwise.

3. Type C
Cylindrical bulb: move aside the contacts.

4. Type D -E
Halogen bulb: release the retaining spring from its housing.
High pressure washing
When using this type of washing on
stubborn dirt, do not persist very long on
the headlamps, or on other lamps and their
surrounds to avoid damaging their coating
and their seal.

TROUBLESHOOTING
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.
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.

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.

Windscreen wash level
For best quality cleaning and for your safety,
we would advise that you use products of
the CITROËN Universal range.
Capacity of the reservoir: approximately
5.5 litres.
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 a
dealership.
Slacken the cap by two turns 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 dealer as soon as possible.

Checks
CHECKS

Bleeding the water contained in the
diesel filter
If this warning light comes on,
bleed the filter, otherwise bleed
regularly each time the engine is
drained.
To evacuate the water, unscrew the bleed
screw or the water in diesel sensor, located
at the base of the filter. Operate 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 it checked by a
CITROËN dealer.
Air fi lter and passenger compartment fi lter
A clogged passenger compartment filter
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.

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 circuit, 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, consult a
CITROËN dealer.
Handbrake
Where the handbrake travel is too great
or there is a reduction in the performance
of the system, the handbrake should be
adjusted, even between services.
Have it checked by a CITROËN dealer.

Oil filter
Change the filter regularly, in accordance
with the servicing schedule.
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 characteristics.
In order to optimise the operation of units as
important as the braking circuit, 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.
