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.

Security Systems
The primary protection for your DB AR1 is provided by an electronic
security system. Protection is further enhanced by a passive anti-theft system
(PATS) which provides engine immobilisation measures if the wrong ignition
key is used. The total system has the following functions:
• Remote Arming/Disarming via a Key Fob.
• Perimeter Sensing via switches on the doors, boot lid and bonnet.
• Boot Release on the Key Fob.
• Panic Alarm triggered using the Alarm Key Fob.
• 120dB Siren with battery back-up (in markets where audible sirens are
permitted).
• Random Code Encryption to prevent electronic scanning or grabbing of
the key fob identity code.
• Passive Anti-Theft system.
Tracker System (Optional - UK only excluding Channel Isles)
• The Tracker hardware is fitted to UK cars only and may be activated for
any owners who wish to subscribe to this additional vehicle security
system. Please consult your dealer for system details and subscription
rates.

System Operation - Basic Controls
The system is controlled using the two button key fob. The left (key symbol)
button controls the normal locking/unlocking of the car and arms/disarms
the alarm system. The right (boot open symbol) button controls the
unlocking of the boot. The Panic Alarm feature is operated using the left key
fob button.
The security system aerial is located at the rear of the car. The key fob should
be pointed towards this area of the vehicle to ensure a strong signal. The
normal operating range of the key fob is approximately 10 metres (30 feet).
The Passive Anti-Theft feature is fully automatic and is operated via a
transponder in the ignition key head which communicates with the engine
immobiliser circuits.

Full Alarm Activation
When activated, the siren sounds for 30 seconds (in markets where audible
sirens are permitted) and the direction indicators flash (in markets where
visible alarm signals are permitted). After 5 minutes the alarm stops (i.e. the
direction indicators stop flashing) and returns to the armed state. The doors,
boot and filler flap remain locked throughout.
The alarm can be deactivated by pressing the left (Key) button on the key
fob. This will also disarm the alarm and unlock the doors and filler flap.
Panic Alarm
The system has a panic alarm feature which can be activated whatever the
alarm state. This feature may be used to discourage offenders when you are
either inside the car or within the operating range of the alarm key fob
(approximately 10 metres / 30 feet).
To activate the panic alarm, press and hold the left key fob button for at least
three seconds. The system will enter the full alarm state.
Press the key fob left button again to stop the panic alarm and return to the
state prior to initial panic alarm activation.
If the panic alarm is not switched off using the left button, the siren will stop
after 30 seconds and the indicator flashing will deactivate after 5 minutes.
