Fuel Filling
The unleaded fuel tank filler neck has a restricted opening which will only
accommodate the fuel supply nozzle of unleaded fuel pumps.
To avoid fuel spillage, stop filling at the first automatic cutoff of the fuel
supply nozzle.
Catalytic Converters
The DB AR1 exhaust system contains 3-way catalytic convertors which
convert harmful exhaust gasses into less noxious substances and so reduce
environmental pollution. Catalytic converters operate at high temperatures
and continue to radiate a considerable amount of heat after turning off the
engine.
WARNINGS: Leaded fuel will cause irreparable damage to the catalytic converters.
If you do inadvertently put leaded fuel into a DB AR1, DO NOT START THE
ENGINE. DO NOT DRIVE THE CAR. Contact your Aston Martin Dealer immediately.
Do not park over dry grass, leaves or other combustible material. A significant
fire risk exists because of residual heat in the catalytic converters.
Do not drive through deep water. The rapid cooling of the catalyst may cause it
to break up. Replacement catalytic converters are expensive.

Stopping the Engine - Removing the Ignition Key
To stop the engine, turn the ignition key anti-clockwise to position 0.
The ignition key is interlocked with the gear selector lever on automatic
transmission vehicles so that the key may only be removed from the ignition
lock when the gear selector lever is in the Park position.
Note: If the Ignition Key is left in positions I or II and a door is opened, a warning
chime will sound to advise removal of the key.
Fuel Cut-Off Switch
Your DB AR1 is fitted with an emergency
fuel cut-off inertia switch mounted on the
passenger side door pillar. This switch
operates to cut-off fuel supply to the
engine in the event of an accident, thereby
reducing fire risk.
If the engine cuts out and then does not
restart in such a situation, open the
passenger door and press the top of the
cut-off switch until it latches down. With
the ignition on, the fuel pumps will then
run and fuel will again be supplied to the
engine. Restart the engine as normal.
WARNING: To avoid the possibility of fire, do not reset the fuel cut-off switch if
you smell fuel.

Introduction
Owner Maintenance
Each item in the Service Schedules must be performed on time as failure to
do so may void the New Car Warranty or other warranties. It is the owner's
responsibility to see that the vehicle is maintained properly and in accordance
with the manufacturer's service schedules.
Due to the sophistication of the various systems and the specialised
equipment required to maintain the DB AR1, owner maintenance should
be restricted to the routine procedures given in this Owner's Guide. If you
think that the car is not functioning properly, please return it to an Aston
Martin Dealer to be checked professionally.
Electronic Fuel Injection
WARNING: Electronic Fuel Injection: If the fuel system is allowed to run dry
irreparable damage to the fuel pumps may occur.
The electronic fuel injection system requires special equipment and test
facilities to set up and maintain so that the car gives maximum performance
coupled with economy and reliability. You are, therefore, strongly advised
to entrust all service work to an Aston Martin dealer.
WARNING: Any modifications/additions to the fuel system not specifically
designed by Aston Martin are prohibited. If done, they may cause damage to the
fuel system which in some circumstances could result in fire. It is recommended
that all Service Field Actions are entrusted to an Aston Martin dealer.
