ECU ASTON MARTIN DB AR1 Q 2003 Owners Guide

F - Owner Maintenance
1-F-27 The DB AR1 may then be winched onto a transporter or towed to a safe
location using a rope, provided that the following precautions are observed:
Transporting
If the vehicle is to be transported on a trailer or flat bed transporter, the
handbrake must be applied and the wheels chocked. Vehicles fitted with
Touchtronic transmission must have the gear selector lever moved to N or
D but NEVER in P. The parking lock may be damaged if the vehicle is
transported with the gear selector lever in P.
Four tie-down brackets are provided, two on each axle. These are NOT
suitable for solid bar towing.
Front Axle Tie-Down Rear Axle Tie Down
Vehicles with Defective Touchtronic Transmission
The vehicle must be carried on a transporter or towed with the rear wheels
clear of the ground (see suspended towing) or towed with the propeller shaft
disconnected at the final drive input flange. If the propeller shaft is
disconnected, it must be firmly secured away from the final drive flange.

1-F-28
Suspended Towing
Do NOT tow with sling-type equipment since damage to the bodywork may
result.
Take care when using 'spectacle frame' type towing equipment that the
towing device is well clear of the front or rear apron. Body damage may
occur if the vehicles pass over uneven road surfaces.
Adhere to Towing Regulations
In certain countries the registration number of the towing vehicle and an ON
TOW sign or warning triangle must be displayed in a prominent position at
the rear of the vehicle being towed.
Front Suspended Tow
Caution: To prevent body damage ensure an adequate clearance is
maintained between the car body and (1) the ground and (2) the 'spectacle
frame' of the towing vehicle while your car is being towed.
1. Remove the ignition key from the ignition.
2. Vehicles with manual transmission: Place the gear lever in neutral.
Vehicles with automatic transmission:
Disconnect the propeller shaft at the final drive input flange.
Ensure that the propeller shaft is firmly secured away from the final drive
input flange.

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-32
The Battery Disconnect Switch
The battery disconnect switch is located in the R/H side wall trim panel of
the boot. When actuated, power to all control modules is disconnected and
only ‘keep alive memory’ power is maintained. Thus the quiescent power
drain on the battery is greatly reduced.
To maintain the battery charge level, press the battery disconnect switch and
use the battery conditioner to charge the battery whenever the vehicle is to
be out of use for some days.
If the battery disconnect function is used in conjunction with the battery
conditioner, the vehicle may be stored for many months without additional
battery maintenance.
Caution: The vehicle security systems will be totally disabled when the battery
disconnect switch is used. The vehicle will be secured only by the mechanical door
locks. Ensure that the vehicle is stored in a secure location.
Caution: Close and lock the doors before disconnecting the battery. The door window
seals will be damaged if the door is closed or opened when the battery is disconnected.
