2009 Citroen NEMO DAG air condition

108
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, ...).

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 filter and passenger compartment
filter
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.

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.
