2008 Citroen NEMO engine

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 a CITROËN towbar is
used (see the “Rear parking assistance”
section of chapter 4).
Towbar
We recommend the use of 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 1000 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, etc.).

BATTERY

A. Positive metal point on your vehicle

B. Slave battery

C. Earth on your vehicle
CHARGING THE BATTERY USING A CHARGER
- disconnect the battery,
- 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.
STARTING FROM ANOTHER BATTERY
- connect the red cable to the metal point
A then to the positive (+) terminal of the
slave battery B ,
- connect one end of the green or black cable to the negative (-) terminal of the
slave battery B ,
- connect the other end of the green or black cable to the earth point C on your
vehicle,
- operate the starter, let the engine run,
- wait for the engine to return to idle, then disconnect the cables.

98
Battery
The batteries contain harmful
substances such as sulphuric acid and
lead. They must be discarded in accordance
with the provisions of the law and must not,
in any circumstances, be discarded with
household waste.
Take used batteries to a special collection
point.
Before disconnecting the battery, you must
wait for 2 minutes after switching off the
ignition.
Never disconnect a terminal when the
engine is running.
Never charge a battery without first
disconnecting the terminals.
Close the windows and doors before
disconnecting the battery.
After every reconnection of the battery,
switch on the ignition and wait 1 minute
before starting to allow the electronic
systems to be initialised. If slight difficulties
are experienced after this, please consult a
CITROËN dealer . It is advisable to disconnect the battery
if the vehicle is not to be used for a
period of more than one month.
If the battery has been disconnected
for some time, it may be necessary to
reinitialise the following functions:
- the display parameters (date, time, language, distance unit and temperature
unit),
- the radio stations,
- the central locking.
Some settings are cleared and must be
reprogrammed, consult a CITROËN dealer .

Having your vehicle towed
BEING TOWED
Without lifting (four wheels on the ground)
You must always use a towbar.
From the front
The removable towing eye is located in the
tool kit behind the driver ’s seat (Van) or
behind the rear benchseat (Combi).
Unclip the cover using a flat tool.
Screw the removable towing eye in fully.
From the rear
Hook the bar onto the rigid eye located
under the bumper.
With lifting (2 wheels only on the ground)
It is preferable to lift the vehicle using
professional lifting equipment. When being towed with the engine
off, there is no braking or steering
assistance.

Fuel
FILLING WITH FUEL
Low fuel level
When the minimum fuel tank
level is reached, this warning
light comes on. At this moment,
you have approximately 6 litres
remaining. 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.
- Hold the cap with one hand.
- With the other hand, insert the key and turn it a third of a turn.
- Remove the cap.
FUEL CIRCUIT DEACTIVATED
In the event of a serious collision, a device
automatically cuts off the fuel supply to the
engine and the vehicle’s electrical supply.
This also automatically unlocks the doors
and switches on the interior lights.
A message is displayed on the instrument
panel (depending on model).
Turn the key to position STOP to avoid the
battery being discharged.

Check that there is no smell or leak of fuel
outside the vehicle.
When the fuel filler flap is open, a
safety system prevents sliding of the
side door.
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 45 litres.
After filling the fuel tank, lock the cap and
close the flap.
Reactivating
To continue driving, manually re-establish
the fuel supply and the electrical supply :
- with the ignition key in position STOP,
turn it to position RUNNING,
- move the direction indicators control stalk all the way upwards,
- put it to position “Stop”,
- move the direction indicators control stalk all the way downwards,
- put it to position “Stop“ again,
- move it all the way upwards again,
- put it to position “Stop” again,
- move it all the way downwards again,
- put it to position “Stop” again,
- turn the ignition key to position STOP.
