The Ignition Lock
The Ignition Lock, located on the right side of the steering column, performs
the following functions:
• Steering Lock
• Ignition Switch
The switch has three positions:
Position OAll systems off, steering lock engaged.
Position IAuxiliaries on (e.g. radio), steering lock released. Use this
position if the vehicle is being towed.
Position IIIgnition and all other electrical systems on. This is the
normal running position.

Stopping the Engine - Removing the Ignition Key
To stop the engine, turn the ignition key anti-clockwise to position 0.
The ignition key is interlocked with the gear selector lever on automatic
transmission vehicles so that the key may only be removed from the ignition
lock when the gear selector lever is in the Park position.
Note: If the Ignition Key is left in positions I or II and a door is opened, a warning
chime will sound to advise removal of the key.
Fuel Cut-Off Switch
Your DB AR1 is fitted with an emergency
fuel cut-off inertia switch mounted on the
passenger side door pillar. This switch
operates to cut-off fuel supply to the
engine in the event of an accident, thereby
reducing fire risk.
If the engine cuts out and then does not
restart in such a situation, open the
passenger door and press the top of the
cut-off switch until it latches down. With
the ignition on, the fuel pumps will then
run and fuel will again be supplied to the
engine. Restart the engine as normal.
WARNING: To avoid the possibility of fire, do not reset the fuel cut-off switch if
you smell fuel.

Gear Changing
When operating either the DB AR1 manual or Touchtronic transmission
systems, the following warnings are of particular importance:
WARNING: Do not skip one or more gears when downshifting, you could lose
control of the vehicle and injury could result.
WARNING: Shifting without correct operation of the clutch and throttle can
result in severe damage to the transmission and engine.
Gear Changing - Manual Transmission
The gear lever for the six speed manual transmission is spring biased to the
centre of the gate. Push to the left before selecting first or second gears and
to the right before selecting fifth or sixth gear.
Press fully to the right and forwards to overcome additional spring pressure
when selecting reverse gear. The reverse gear position has a solenoid lock
to prevent accidental engagement when driving forward.

Additional Automatic Gearbox Functions
Kickdown (Automatic and Sport Modes Only)
If maximum power is demanded from the engine by opening the throttle to
more than about 95%, the kickdown function is automatically actuated.
With kickdown in operation, the gearbox may shift to the next lower gear
and further upshifts will occur at much higher engine speeds than when
using modest throttle openings. This mode is useful to achieve maximum
acceleration when, for example, overtaking another vehicle.
Torque Converter Lock-up
When driving in 3rd, 4th or 5th gears, a further change takes place within
the transmission. The torque convertor, transmitting power from engine to
transmission, will lock to improve the transmission efficiency. This is a
completely automatic function of the transmission system and will occur at
predetermined speeds.

The Braking Systems
The Footbrake System
Your DB AR1 uses a vacuum boosted hydraulic braking system with anti-
lock (ABS) function. This system ensures braking performance in keeping
with the vehicle performance.
The Anti-Lock Braking System (ABS) is continually monitored for correct
operation whilst the ignition is switched on. Should a fault occur, it will be
signalled by the Anti-Lock Warning Light.
Brake System Safety Features
The brake system tandem master cylinder is designed so that in the worst
case (barring major accident damage), only half the brake system could fail.
Even in the event of a major brake pipe fracture, at least two wheels will have
fully operative brakes.

Anti-Lock Braking System (ABS)
The anti-lock braking system (ABS) fitted to the DB AR1 helps prevent the
road wheels from locking and skidding during emergency braking, helping
steering and directional stability to be maintained.
If, in an emergency braking situation, the braking force applied begins to
exceed the tyre/road adhesion, the ABS system is activated to prevent the
road wheels locking. When this happens a pulsating effect is felt through the
brake pedal. This is a normal ABS effect.
WARNING: In all cases it remains the drivers responsibility to drive safely
according to the law and with due regard to prevailing conditions. The fact that
a vehicle is equipped with ABS must never allow the driver to be tempted into
taking risks which could affect his/her safety or that of other road users. The
addition of ABS cannot overcome the consequences of trying to stop in too short
a distance, cornering at too high a speed, or the risk of aquaplaning - where the
tyres are prevented from contacting the road surface by a layer of water.
The driver should always take road conditions into account. A slippery road
surface always requires more braking distance for a given speed, even with ABS.
Possible extensions of stopping distance compared to locked wheels may occur
during ABS operation on slushy snow, gravel, sand or certain heavily corrugated
or ridged warning sections of road surfaces.

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.

The Handbrake (Parking Brake)
The handbrake lever is situated on the outside of the drivers seat. The
handbrake operates on brake drums within the rear wheel brake discs.
To engage the handbrake, pull up firmly on the lever without pressing the
release button. The handbrake ratchet will latch and the handbrake warning
light will illuminate. Note that this lamp is the only indication that the
handbrake is applied. The lever can then be lowered to its fully down
position.
To release the handbrake, pull up on the lever against spring pressure, press
and hold the lock release button whilst lowering the lever to its maximum
down position.
The handbrake warning light extinguishes when the handbrake is fully
released.
Caution: Always check that the warning lamp is correctly extinguished before moving
off. Do not attempt to drive the vehicle if the warning lamp remains on.
