2003 ASTON MARTIN DB AR1 Q air condition

Air Conditioning Controls
The air conditioning controls are located on two panels mounted either side
of the clock on the centre console.
Left Panel
The left panel contains the temperature and fan speed controls.
Temperature Control
This control sets the desired in-car temperature for the
system. Incoming air is cooled and then heated or
blended as required to maintain the in-car temperature
at the set level within the operating range of the system.
Fan Speed Control
This five position switch is used to set the fan speed: Off
(Fan symbol), 1-Low, 2-Medium, 3-High and Defrost.
In Defrost mode the fans run at high speed and supply
air to the windscreen and side screen vents only.
When the system is switched Off, (Fan symbol) the
complete system is OFF. The external air inlets are
closed, cutting off fresh air supply from outside the car.

D - Heating, Ventilation & Air Conditioning
1-D-6Defrost (A/C Off)
In defrost mode, the system is automatically switched
to high fan speed and maximum heat with no air
conditioning. The hot air is directed to the screen and
door vents only. The door vents may be closed to
direct maximum air flow to the screen.
Right Panel (A/C Mode Switch)
The right panel contains the mode switch and temperature differential
controls.
The mode switch settings are:
Economy (A/C off)
Manual Control
Auto Control
Demist
Recirculation
ECON (Economy)
In the ECON position, the air conditioning compressor is switched off.
Incoming air can be heated if required and the fan speed can be adjusted
to increase or decrease the airflow in the vehicle. This mode puts minimum
load on the engine and gives the best fuel economy with no air conditioning
(no cooling or dehumidifying of incoming air).

1-D-7 MAN (Manual)
In Manual mode, the air delivered from the vents
remains at the temperature set on the temperature
control regardless of the temperature inside the
passenger compartment. In this mode, incoming
air is also dehumidified and blended.
AUTO Control
This is the automatic mode of operation in which
the heating and cooling functions of the system
operate automatically, as required, to maintain
the selected in-car temperature. In this mode,
incoming air is also dehumidified and blended.
Note: If the incoming air requires little heating or cooling when in AC mode, the
centre vent will close reducing the air flow in the upper part of the passenger
compartment. If more airflow is required, the Demist function can be used to
provide the same temperature level but with increased air flow to the windscreen
vents.

D - Heating, Ventilation & Air Conditioning
1-D-8DEM (Demist)
When this mode is selected heated air is directed to
the windscreen vents for demisting as well as to the
face level, footwell and door vents. Air speed and
temperature depend upon the fan speed, in-car
temperature selected and engine temperature.
Recirculation
In Recirculation mode, all external air inlets are
closed and conditions within the vehicle are
maintained by drawing air from within the cabin and
heating or cooling it as required before returning it
to the passenger compartment.
Recirculation mode avoids drawing noxious fumes
into the vehicle from outside. This mode is not
recommended for continuous use since no fresh air
is drawn into the vehicle and drowsiness may occur.
The car interior may be rapidly cooled in recirculation
mode by selecting Recirculation, Minimum
Temperature and Fan Speed 3.

Temperature Differential Control
This control sets the difference in temperature
between the air from the face vents and that from
the footwell vents.
To provide cooler air to the face, the differential
control should be set fully anticlockwise. If the
control is set fully clockwise, the air from the face
vents will be at the same temperature as that from
the footwell vents.
The differential control is only effective when the
temperature control is set to its mid position.

WARNINGS:
To help avoid personal injury, do not use open flame, smoke, or cause an electric
spark when checking the battery, as gas generated by the battery is flammable
and can explode. Always shield your eyes and avoid leaning over the battery.
Do not ingest battery acid or fumes. If battery acid is ingested, drink large
quantities of water or milk followed by milk of magnesia, beaten egg or vegetable
oil. Call for medical assistance immediately.
Do not let battery acid come into contact with skin, eyes, hair, fabric or painted
surfaces. A solution of warm soapy water and baking soda may help neutralise
acid.
Used batteries contain sulphuric acid, lead and other potentially hazardous
materials. Dispose of unwanted batteries in authorised waste disposal facilities.
DO NOT discard unwanted batteries in household waste.
Quiescent Battery Drain
Any power drain from a battery after the ignition is switched off is referred
to as 'quiescent battery drain'. Your DB AR1, in common with many modern,
high technology motor cars, contains electronic circuits and sub-systems
which must be left activated at all times. For example, the clock, security
systems and in-car entertainment system continue to drain battery power
even with the ignition switched off. This quiescent drain will discharge a fully
charged new battery in approximately 30 days unless recharged by normal
engine running or an independent battery charger.
It is therefore vital that, when leaving your car unused for extended
periods, you use the battery disconnect switch to minimise quiescent
drain and that you use the battery conditioner to maintain battery
charge level.
