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.

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.

Locking the Car, Arming the Alarm
Point the key fob towards the rear window and press the left button. The
following events will occur:
1. The green light on the key fob will light while the left button is pressed.
2. The car doors and fuel filler flap will lock.
3. The direction indicators will flash once (in markets where visible alarm
signals are permitted).
4. The alarm system will be switched on.
Alarm and Security System Protection
With the alarm system armed, any attempt to open a door, the boot or the
bonnet will result in full alarm activation.

The Passive Anti-Theft System (PATs)
The PATs system is a fully automatic engine immobiliser. The system consists
of a transponder inside the head of each ignition key and, around the
ignition lock, a transceiver aerial which communicates signals to the PATs
electronic control unit. The PATs control unit communicates with the engine
management controller to immobilise the engine until a valid code signal is
received from the ignition key.
Two coded keys are provided with the vehicle. These
keys fit both the door locks, the boot lock and the ignition
lock.
In the event of loss of one of the keys, duplicate keys can
be created and programmed from the other key by your
Aston Martin dealer.
Starting the Engine
When the alarm system is disarmed and the vehicle key is turned in the
ignition lock, the PATs controller sends a signal to the ignition key. The
ignition key must respond with a valid code before engine start will be
enabled. If a valid code is received, the ignition system will operate
normally.
If the key code is not received, or is invalid, engine start remains disabled.
Caution: To ensure a trouble-free signal exchange between the key and the vehicle,
do not cover the key head with any metal object (e.g. another key).

Parts and Lubricants
When undertaking a warranty servicing task, only parts, materials,
lubricants etc. that are specifically recommended by Aston Martin
Lagonda Limited should be used. Failure to do so can result in
damage to the vehicle and invalidate the New Car Warranty or
other warranties. Recommended lubricants, capacities, etc. may be
found in the Specifications section of this Owner's Guide, and are
recommended for use at all routine services whether or not under
warranty.
Emissions Warranty
The emission control systems fitted to cars for certain markets are
covered by a separate emissions warranty. A statement of the provisions
is given in the Warranty section of this Owner's Guide. You are
advised to familiarise yourself with all warranty conditions prior to
taking delivery of your car.
Engine Compartment Covers
The primary fluid level checks and reservoirs within the engine
compartment are all immediately accessible. The less frequently
maintained items are located under the engine compartment side
covers. To remove the covers, use a coin or the tool kit screwdriver
to turn the cover fasteners a quarter turn anti-clockwise. The fasteners
will pop-up and the covers can then be lifted off, along with a
rubber protection strip.
When replacing the covers, fit them into place and secure by pushing
down on each fastener and turn it a quarter turn clockwise until it
locks, then insert the rubber protection strip.

Servicing Precautions
To avoid personal injury, the following safety precautions must be observed
when the bonnet is open and the engine is running or the ignition is switched
on.
WARNINGS:
Keep hands, hair, tools, items of clothing and jewellery clear of all drive belts,
pulleys and operating mechanisms. The cooling fans may operate even though
the engine is not running. The windscreen wiper mechanism is fitted with an
intermittent delay facility and may operate unexpectedly if left switched on.
Carbon monoxide is a dangerous gas and can cause unconsciousness and may be
fatal. Do not breathe exhaust gas as it contains carbon monoxide which by itself
has no colour or odour. Never start or leave the engine running in an enclosed,
unventilated area.
Avoid skin contact with all exhaust system and engine components, engine fluids
and escaping steam. They may be hot and will burn you.
Whenever possible work in the engine compartment with the engine cool, the
ignition switched off and the battery disconnected.
Do not work beneath the car with the vehicle lifting jack as the only support.
Place suitable stands under the car.
Keep children and pets clear of the car. Do not allow anyone inside the car unless
specifically working to your instructions.

Dangerous Substances
WARNING: Many liquids and other substances used in motor vehicles are
poisonous and should under no circumstances be consumed and should, so far
as possible, be kept from contact with the skin. These substances include battery
electrolyte, antifreeze, oil, brake and clutch fluid, petrol, windscreen washer
additives, lubricants, refrigerant and various adhesives. Particular care should
be taken to avoid unnecessary contact with used engine oil. Always read carefully
the instructions printed on labels or stamped on components and follow them
carefully. Such instructions are included for reasons of your health and personal
safety. Never disregard them. Dangerous substances should be kept out of reach
of children.
Engine Oils
WARNING: Prolonged and repeated contact with used engine oils can cause
serious skin disorders, including dermatitis and cancer. Avoid excessive contact,
wash thoroughly after contact. Keep out of reach of children. When your oil is
changed, be sure that it is done by an experienced person. In addition, observe
all laws regarding the disposal of waste oil and toxic fluids.
Protect The Environment
WARNING: It is illegal to pollute drains, water courses, or soil. Use authorised
waste disposal facilities, including civic amenity sites and garages providing
facilities for receipt of used oil. If in doubt, contact your local authority for advice.
Fuel Tank Filling
WARNING: Petrol is highly flammable and, in confined spaces, is also explosive
and toxic. In the event of spillage, switch off the engine, use no naked flame or
light. Do not smoke. Do not inhale fumes.
