Regular Checks
In the interests of safety and reliability, it is advisable to carry out the
following checks at the intervals suggested (more frequently if the vehicle is
heavily used or operating in adverse conditions), and always before starting
on a long journey. Refer to the Owner Maintenance section of this guide.
Each Day
Check that there is sufficient fuel for the intended journey, particularly at
night and before entering highways.
Weekly - (Daily if covering high mileage or touring)
Tyres - Check the tyres, including the spare (if fitted) for condition and
pressure. See the 'Specifications' section for the recommended tyre pressures.
Lights - Check that all exterior lights and direction indicators function
correctly and that the lenses are clean.
Engine Oil - With the vehicle standing on level ground, check the oil level
and top up if necessary with oil of the correct grade.
Engine Cooling System - With the engine cold, check the level of the engine
coolant. Top-up if necessary with coolant containing the required percentage
of anti-freeze. Any significant coolant loss should be investigated by your
Aston Martin Dealer.
Brake Fluid - Check the level of the fluid in the brake reservoir. Top-up if
necessary with the specified brake fluid from a new unopened container.
Power Steering Fluid - Check and top-up the level of fluid in the power
steering reservoir with fluid of the correct specification.

Note: Items 5 &7 move to the left corner on left hand drive cars.
In the following descriptions, numbers in parenthesis, e.g. (1), refer to the
numbered items in the diagram and list above.
All directions are described as viewed from the driver's seat. Thus the oil filler cap
(item 3) is on the left side of the car, the brake fluid reservoir (item 5) is on the right
side of the car.

Power Steering Fluid Level Check
The power steering pump reservoir (4) is situated on the right inner
wing.
The reservoir level should be checked when the engine is cold. The
reservoir cap incorporates a dipstick. Top up the reservoir with clean
fluid of the recommended grade up to the lower mark on the dipstick.
DO NOT OVERFILL.
WARNING: Avoid touching the sides of the engine when working in the engine
compartment. The exhaust system will be hot if the engine has recently been run.
Caution: Take care that hydraulic fluid does not contact the paint work during the
topping up operation. Serious paint work damage can result. If a spillage does occur,
immediately flush the hydraulic fluid from the paint work with clean, fresh water and
then wipe with a clean damp cloth.

1-F-29 3. Raise the vehicle using a 'spectacle frame' type lifting device with a cradle
positioned under each front wheel as shown below.
Rear 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/steering lock.
2. Raise the vehicle using a 'spectacle frame' style lifting device where a
cradle is positioned under each rear wheel as indicated below.
Towing by Another Vehicle
WARNING: When the engine is stationary, there will be no power assistance to
the steering or brakes. Therefore be prepared for relatively heavy steering and
the need for greatly increased brake pedal pressure.
The vehicle may be towed short distances by another provided that a speed
of 48 km/h (30 mph) is not exceeded. Do not tow for more than 24km (15
miles). When being towed, the vehicles gear lever, or gear selector lever
(automatic transmission), must be in Neutral or position N with the ignition
key turned to position II to release the steering lock and to render the horn,
indicators and brake lights operational.
