Electrical Start from Another Vehicle
If your DB AR1 will not start due to a discharged battery, it may be started
by connecting the battery from another vehicle to the discharged battery.
Before the vehicle is started in this way, ensure that the donor vehicle has
a 12 volt battery and negative (-), black earth terminal to ensure that the
correct battery polarity is maintained.
WARNING: If the voltage or earth of the donor vehicle is different or not known,
do not attempt starting in the way described.
1. Position the vehicles so that the connecting cable will reach between
the batteries. Ensure that the vehicles do not touch each other.
2. To lessen the risk of an electrical short circuit, remove rings, metal
watch bands and any other jewellery. Wear eye protection when
working near the battery. Turn off all electrical motors and ancillaries
in both vehicles. Switch off all lights except those needed to protect the
vehicles or illuminate the work area. Switch off the ignition and apply
the handbrake.
3. Lift out the boot floor panels to gain access to the battery.
4. Connect the red (+) cable between the red (+) positive terminal of the
two batteries.
5. Connect the black (-) cable between the black (-) negative terminals of
the two batteries.
6. Start the donor vehicle engine and run at about 1500 - 2000 rpm.
7. Start the engine. Allow the engine to run for some minutes until the flat
battery is partially charged. Switch off both vehicles.

remove the red (+) positive cable from both batteries.
9. Refit the boot floor panels and close the boot.
10. Restart the engine and take it for a long road run if possible to recharge
the battery.
11. If necessary, recharge the battery using an appropriate 'trickle' charger.

Fuse Boxes
Three fuse/relay boxes are fitted to DB AR1 containing the fuses to protect
electrical and electronic systems of the vehicle. The box locations are
indicated on the diagram above.
The forward left and right fuse boxes are located beneath a plate in the
passenger side footwell. The rear fuse box is located in the boot, close to the
battery.
WARNING: Do not add to or alter the electrical systems of DB AR1 unless fitting
Aston Martin approved options to the manufacturers instructions. Use of
unapproved components, incorrect dismantling, incorrect reassembly or incorrect
replacement of components may create electrical overloads and a fire risk.
WARNING: Do not attempt to repair a blown fuse. This could cause a fire hazard
or serious damage elsewhere in the electrical circuits.
WARNING: Do not install a fuse which exceeds the amperage for each location
listed on the following fuse charts.

Door Edge Lights
1. Taking care to protect the paint
work, use a screwdriver to lever the
light assembly from its location in
the lower door edge.
2. Remove the bulb from the light
assembly and fit a replacement bulb.
3. Refit the assembly to the door,
pushing firmly until it clips into place.
Central High Mounted Stop Lamp
The high mounted stop lamp is fitted in the boot lid. It is recommended that
your have your dealer change the high mounted stop lamp if necessary.
Electric Window Reset Procedure
If either the battery or the window controllers are disconnected, the window
controller will lose its memory of the window maximum up and down
positions. The window controller memory may be checked and reset as
follows:

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.

Recommissioning After Storage
Provided that the car has been stored in accordance with the recommended
procedure, the following points only should require attention before using
the car on the road.
Check the tyre pressures, inflate if necessary and lower the car to the ground.
Fully charge and refit the battery. Reset the clock and electric windows.
Drain the engine sump and final drive unit, fit a new engine oil filter element,
then refill with the approved oils. Check the coolant level and if necessary
top up with the correct antifreeze/water solution.
Check all fluid levels and top-up as necessary. Fill the fuel tank
Caution: Starting the engine without sufficient lubrication can cause serious engine
damage. Take care to establish engine oil pressure as directed in the following steps
before allowing the engine to start.
Press and hold the accelerator hard to the floor (kickdown switch actuated).
This will temporarily inhibit the fuel injectors during cranking. Turn on the
ignition. Press and hold the starter button to crank the engine until normal
oil pressure is indicated on the oil pressure gauge. Release the starter button
and the accelerator pedal.
Start the engine normally and check that the oil pressure and ignition
warning lights go out as the engine starts indicating correct oil pressure and
battery charging. Raise the bonnet and check for leaks of fuel, oil and
coolant.
Finally, check the operation of all instruments, lights and accessories.
