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.

On Board Headlight Aiming (where fitted)
The headlight assemblies (main and dipped beam lights) are factory set to
give correct forward illumination under average load conditions. Should
your headlight aiming require adjustment, it may be corrected as follows:
1. Ensure that the tyres are inflated to the specified pressures.
2. Fill the car with fuel.
3. Park the car on level ground.
NOTE: Any error in ground level will adversely influence the accuracy of the
vertical beam alignment check
4. Have an adult person sit in the drivers seat.
5. Load the boot with the normal items you carry.
6. Open the bonnet.
Horizontal Beam Alignment Check
1. Check the gauge labelled Horizontal Angle Gauge. The green line on the
collar must be aligned with the pointer at the side of the spirit level. If
adjustment is required, rotate the screw and collar until the green line
is aligned with the pointer.

Care and Maintenance of Seat Belts
To ensure that they are in proper working order, regularly check the seat
belts. Look for fraying, cuts, burns and similar problems. Ensure that the
latches and buckles function correctly. If a belt is not in good condition or
is not working properly, consult your Aston Martin Dealer.
Any belt that has been worn during a serious collision should be replaced
by an Aston Martin dealer.
To clean the belts, use mild soap and water; do not use bleach, solvents or
dyes as they can weaken the material. Allow the belts to dry before use.
WARNING: In the interest of safety, do not allow seat belts to be retracted until
completely dry.
Underbonnet Cleaning
Underbonnet cleaning using high pressure hoses or steam cleaners should
not be done. The electronic control modules and fuse boxes will be
damaged by indiscriminate use of high pressure cleaning equipment.
Aerial Care
Regular cleaning with a special aerial cleaner will ensure smooth and reliable
operation of the aerial.
Always wipe the aerial in an upwards direction
Lubricate using an aerial maintenance wipe cloth.
In freezing conditions, check that no ice has formed over the top of the
aerial, which could prevent it being raised and cause damage to the motor.

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.
