D - Heating, Ventilation & Air Conditioning
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.

1-F-53 Window Controller Memory Check
With the alarm off and the doors unlocked, open and then close each door
in turn. If the door window drops on opening and rises on closing the door,
the window controller memory is good. If the windows do not drop and rise
correctly, reset the window controllers as follows:
Window Controller Memory Reset Procedure
1. Sit in the drivers seat with the doors closed. Turn on the ignition switch.
2. Press and hold down the window Down button until the window drops
to its maximum down position in one movement.
3. Press and hold the window Up button until the window rises to its
maximum up position in one movement.
4. Switch off the ignition, step out of the car and close the doors. Perform
the Window Controller Memory Check to ensure that the window
maximum up and down positions have been correctly reset.
Headlamp Ventilation
In very humid conditions some condensation may accumulate within the
headlamp pod enclosures whilst the engine is stopped. When the vehicle
is running and the air conditioning is switched on, the headlamp pod
enclosures are automatically vented and any condensation will clear within
a few minutes.
For rapid headlamp ventilation, use the following settings: A/C On, Fan
speed 3, Interior vents all closed. If the condensation does not clear quickly,
consult your Aston Martin dealer.

Storing the Car - Recommendations
Note: These recommendations apply to new and pre-owned cars either in
Dealer or customer ownership.
When ever the car is not in use always cover the car with it's fabric cover.
If the vehicle is not to be used for periods up to six months it should be stored
in a dry, well ventilated building.
Drive the car for a sufficient distance to warm the oil in the engine, torque
convertor, transmission and final drive unit; this ensures complete lubrication
of the internal components.
Check the engine coolant level. Top up if necessary with the correct
antifreeze/water solution.
In order to take the weight off the tyres, raise the car with a jack and place
supports under the front and rear suspension.
If the vehicle is not raised from the ground, increase the tyre pressures to 3.4
bar 340 kpa 50 psi. Cover the tyres to exclude any light. Rotate the wheels
1/4 turn every month to avoid tyre flat spots.
The battery should be removed and cleaned. Fully charge the battery on a
trickle charger and recharge once a month.
Once a month
Reconnect the battery and ventilate the storage area. Start and run the
engine until fully warmed up. Check that there are no fluid leaks. Check
and correct the tyre pressures if necessary.
Run the Air Conditioning system to keep the internal parts of the Air
Conditioning system lubricated.

F - Owner Maintenance
1-F-59 When returning the car to normal service, set the tyre pressures to normal
specification before driving on the road.
Extended Storage
For storage periods exceeding six months the following additional measures
are recommended;
Run the car until there is as small a quantity of fuel in the tank as is practical
for storage purposes.
Caution: Do Not Drain The Fuel System
Add Engine Oil to the remaining fuel in the tank to ensure a concentration
of 2% (i.e. 20ml per 1 litre of fuel) and then run the engine for not less than
ten minutes to circulate the mixture thoroughly through the entire fuel
system.
Inspect the rubber connections of the cooling system and have them
renewed if necessary.
Wash the bodywork of the car thoroughly and repair any paint
blisters or patches of rust in order to prevent any further deterioration.
Apply a suitable polish.
Clean the carpets and upholstery thoroughly. Dust them with an
anti-moth powder and store in a dry place. Treat all leather upholstery
with an appropriate leather conditioner.
If the storage building is dry leave the car windows slightly open. If
there is any tendency towards dampness close the car doors and
windows and place an anti-moisture compound such as Silica desiccant
bags in an open metal container inside the car.
Cover the car with it's fabric cover.
