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.

Monthly
Windscreen Washer - Top-up with the recommended windscreen wash
fluid. Check the operation of the windscreen washers. Use the recommended
concentration of additives to prevent freezing in winter conditions. Check
the windscreen wash fluid level more frequently if the wash system is being
heavily used.

briefly and extinguish if the brake fluid level is within specification.
Parking Brake Warning (Red)
Illuminates when the parking brake is applied
with the ignition On.
Low Coolant Level (Red)
Illuminates if the level of the engine coolant in the header is
tank is low.
Oil Pressure Warning Light (Red)
Illuminates when the engine oil pressure falls below minimum.
Do not continue driving if this light remains illuminated.
Consult your Dealer immediately.

Warning Light Indications at Ignition On
As the ignition is switched on, the DB AR1 electronic control units each
complete a self check to ensure correct operation. During these checks, the
warning lights on the instrument panel will illuminate as follows:
• Bulb Check - All warning lamps illuminate for about three seconds as a
bulb check. (The Sport and Transmission Fail lamps are not illuminated
on manual transmission vehicles).
• The Ignition and Oil Pressure warning lights illuminate until the engine
starts.
• The Check Engine light will illuminate during the engine management
self-check and will extinguish when the starter button is pressed.
• The Seat Belt warning light illuminates and a gong sounds for six seconds
if the driver's seat belt is not fastened. On fastening the seat belt, the gong
immediately ceases. The warning lamp extinguishes at the end of the six
second warning period.
• The ABS and Traction Control warning lights illuminate and extinguish
if the system self checks are satisfactory.
• The Brake warning light will illuminate and extinguish if the brake fluid
level is within specification.
• The SRS Airbag warning light will illuminate and extinguish if the SRS
Airbag control system check is satisfactory.
Only the handbrake (parking brake) warning light should stay on after the
engine has started and is running correctly. The handbrake warning light will
extinguish as the handbrake is fully released.
Note: Other Information lights may remain on (e.g. Main Beam Warning or Low
Screen Wash) dependant on the vehicle state and switch settings at the time.

1-C-7 If either the ABS or Brake Fluid Warning lights remain illuminated, refer to
the description of Brake Warnings during Driving later in this section.
Starting the Engine - Hot or Cold
WARNINGS:
Before driving the vehicle, ensure that you are wearing appropriate footwear to
efficiently operate the floor mounted pedals.
Ensure that floor mounted pedal movement is not restricted by floor mats or
other objects trapped beneath the pedals.
Manual Transmission - The engine can only be started with the clutch
pedal fully depressed.
Touchtronic Transmission - The engine can only be started when the gear
selector lever is in Park or Neutral.
Place the gear selector lever in Neutral (Park on Touchtronic vehicles) and
check that the handbrake is applied. Fully depress the clutch pedal on
manual transmission vehicles.
Insert the ignition key and rotate it to position II. Press the
starter button, wait until the engine fires, then release the
starter button.
Note: Do not press the accelerator during engine starting. The Electronic Engine
Management System automatically compensates for cold or hot start conditions
and makes appropriate adjustments to the fuel/air mixture and engine idle speed
without driver intervention.

Brake Warning Indications During Driving
Your DB AR1 electronic control units continue to monitor correct operation
of the braking sub-systems while the vehicle is being driven. Two brake
warning lights are of particular importance.
The Anti Lock Braking (ABS) Warning Light
The ABS system is monitored for correct operation while the
ignition is switched on. If a fault is detected, the Anti-Lock
warning light will illuminate and the ABS system will be partly
or fully disabled.
The normal braking system will continue to function without anti-lock but
with full vacuum boosted braking to all road wheels being maintained. In
the event of an ABS fault, consult your Aston Martin Dealer immediately.
WARNING: If the ABS warning light illuminates, you should be aware that
wheels could lock during extreme braking or when braking on slippery surfaces.
Take additional care to avoid the danger of wheels locking.
The Brake System Warning Light
The braking system is continuously monitored for fluid level.
If only the brake warning light illuminates, it indicates that the
brake fluid has fallen below the acceptable level. It is essential
that the braking system is checked immediately, preferably
by an Aston Martin Dealer.
WARNING: If the brake warning light illuminates, you should
immediately be prepared for possible increased stopping distances
and possible partial failure of the braking system.

Dangerous Substances
WARNING: Many liquids and other substances used in motor vehicles are
poisonous and should under no circumstances be consumed and should, so far
as possible, be kept from contact with the skin. These substances include battery
electrolyte, antifreeze, oil, brake and clutch fluid, petrol, windscreen washer
additives, lubricants, refrigerant and various adhesives. Particular care should
be taken to avoid unnecessary contact with used engine oil. Always read carefully
the instructions printed on labels or stamped on components and follow them
carefully. Such instructions are included for reasons of your health and personal
safety. Never disregard them. Dangerous substances should be kept out of reach
of children.
Engine Oils
WARNING: Prolonged and repeated contact with used engine oils can cause
serious skin disorders, including dermatitis and cancer. Avoid excessive contact,
wash thoroughly after contact. Keep out of reach of children. When your oil is
changed, be sure that it is done by an experienced person. In addition, observe
all laws regarding the disposal of waste oil and toxic fluids.
Protect The Environment
WARNING: It is illegal to pollute drains, water courses, or soil. Use authorised
waste disposal facilities, including civic amenity sites and garages providing
facilities for receipt of used oil. If in doubt, contact your local authority for advice.
Fuel Tank Filling
WARNING: Petrol is highly flammable and, in confined spaces, is also explosive
and toxic. In the event of spillage, switch off the engine, use no naked flame or
light. Do not smoke. Do not inhale fumes.
