2012 CITROEN RELAY air conditioning

54

Ventilation


Comfort value adjustment ring

The settings range between:


- increasing the interior ambient air
temperature HI (High) which goes up to
to a maximum setting of 32,

- cooling the interior ambient air
temperature LO (Low) which goes down
to a setting of 16.



Air distribution

A press illuminates the LED on the buttons
which distribute the air flow towards:
the windscreen and front side
window vents (demisting/
defrosting the windows),
the central and side vents (chest
and face),
the vents in the front and rear
areas (feet).
The combination of buttons permits
improvement of air distribution.


Air flow

Successive presses of this button
increase (+) or reduce (-) the
force of the air flow to the interior.
Intake of exterior air/recirculation of interior air

When the LED is on, the air
recirculates inside the passenger
compartment to prevent the entry of exterior
odours and smoke. This position should be
temporary.
When the ambient air comfort level has been
reached, pressing the button switches the
LED off and reopens the exterior air intake.
Pressing the AUTO
button also restores
the intake of exterior air. Returning to this
position permits renewal of the air in the
passenger compartment and demisting.
Pressing the AUTO
button again restores
the FULL AUTO
function.
Rapid demisting/defrosting

Pressing this control permits
rapid clearing of the windows.
The LED is on.
The system manages the air conditioning,
the flow and intake of air, the defrosting
of the rear screen and provides optimum
distribution of the air to the windscreen and
front side windows.
If your vehicle is fitted with additional
heating, switch it off to ensure rapid and
effective demisting/defrosting.

ADDITIONAL REAR VENTILATION


The controls for this system,
additional to the standard cabin
ventilation system, are on the
lower dashboard, to the right of
the steering wheel.

Air outlet
A press on this control activates
the extraction of air to the
outside; the LED comes on.
Press again to switch off.

Air inlet
A press on this control activates
the entry of air into the cabin; the
LED comes on. Press again to
switch off.

ADDITIONAL HEATING SYSTEMS

Supplementar
y 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 duct 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 passenger compartment heating,
additional to the standard equipment.
It can operate independently of the engine.
Additional heater or programmableadditional heating

This is an additional, programmable and
separate system which heats the Diesel
engine hot coolant loop to make starting
easier.
It improves the demisting and defrosting
performance and that of the heated seats, if
fitted to 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 LED
is on if the heating is activated.
When rapid demisting and
defrosting is required, switch off the control.

Towing a trailer

ACCESSORIE
S


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.

Checks


CHECKS
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.


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.
