2008 Citroen JUMPER DAG air conditioning

52 ADDITIONAL HEATING SYSTEMS
Supplementary heating
On the 2-3 seats version, this is located
under the seat on the driver's side with air
diffusion directed forwards. REAR HEATING AND/OR AIR CONDITIONING
If your vehicle is fitted with an
additional air conditioning unit,
located in the rear of the vehicle:
the distribution rail located in
the roof and the individual diffusion vents
provide a perfect diffusion of cold air.
The warm air diffused at the floor, from the
front air conditioning unit, is distributed at
the feet of the rear passengers of rows 2
and 3.
A warm air diffusion vent, located on the rear
left wheelarch, may complete the assembly
for the feet of the rear passengers of row 3.
Additional heating
This is an additional passenger compartment
heating system which supplements the
standard equipment.
It can operate independently of the engine.
Depending on the level of finish of the
equipment, its start-up can be programmed.
Additional heater or programmable
heating
This is an additional and autonomous
system which heats the diesel engine hot
coolant loop to make starting easier.
It improves the de-icing and demisting
performance and that of the heated seats, if
fitted in the vehicle.
The passenger compartment heating is
brought up to temperature more rapidly.
This system must be programmed to start up
before you enter the vehicle.
On the 5-9 seats version, it is
located at the rear. Depending
on the model version, the air
diffusion is either direct from the
rear or comes from the rail located under
each of the two rows of seats.
Press this control to activate/
deactivate the heating. The diode
is lit if the heating is activated.
When rapid de-icing and
demisting is required, switch off the control.

ACCESSORIES
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
features" section of chapter 9) and of
the trailer, observing the recommended
pressure. 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 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 light 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 assistance: the assistance
does not function while the vehicle is towing.

Checks
CHECKS
Air filter and passenger
compartment filter
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.
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.
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 the system checked by a CITROËN
dealer.
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 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 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, contact a
CITROËN dealer. Oil filter
Change the filter regularly, in accordance
with the servicing schedule.
