2003 ASTON MARTIN DB AR1 Q ABS

C - Driving

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.

Brake Fluid Reservoir
The brake fluid reservoir (5) is fitted to the driver's side of the engine
compartment on top of the brake master cylinder assembly.
Before removing the cap, clean the cap and the surrounding area thoroughly
to prevent ingress of dirt and foreign matter. Top up to the indicated level
on the reservoir with the recommended brake fluid (see 'Specifications') and
refit the cap securely.
Brake fluid will absorb water vapour and must be replaced every two years
in order to maintain the efficiency of the hydraulic system.
WARNINGS: Do not drive the vehicle if the brake fluid level is low. Use only new
DOT4 brake fluid from air tight containers.
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.

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.
