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.

A - Service Schedules
2-A-4
Service Schedules Summary
Your DB AR1 should be serviced every 12,000 km (7,500 miles) or 6 months,
whichever occurs first. The service schedules cover:
Pre-delivery Inspection (PDI)
This free series of checks is carried out on the car by the Selling Dealer before
delivery. The checks ensure that you receive a vehicle which matches the high
quality standards set by Aston Martin Lagonda Limited.
Initial 1,500km (1,000 mile) Service
The Selling Dealer is responsible for the costs and work involved in performing this
free service. The initial service consists of an inspection and oil change service after
completion of the first 1,500 km (1,000 miles) and includes fine adjustments to
compensate for initial 'bedding-in' e.g. handbrake adjustment. Also, engine oil and
filter will be changed to clear any contaminants picked up during the initial running.
12,000 km (7,500 mile) Service
This is the basic service interval for DB AR1 when consumable oils, filters, etc will be
changed and functional checks will be carried out on all major systems in the vehicle.
24,000 km (15,000 mile) Service
In addition to the 12,000 km (7,500 mile) service items, air filters, wiper blades etc.
are renewed at 24,000 km (15,000 mile) intervals.
48,000 & 96,000 km (30,000 & 60,000 mile) Services
Again the basic 12,000 km (7,500 mile) service is carried out together with the
additional checks and replacement items shown in the following schedules.
2 Years
To maintain the hydraulic brake system performance, the brake fluid is renewed
every 2 years to clear the system of absorbed water vapour.
