Anti-Lock Braking System
The Anti-lock Braking System (ABS) helps prevent the road
wheels from locking and causing the vehicle to skid during
emergency braking. This also assists the driver in maintaining
steering and directional stability.
If the braking force exceeds tire grip in an emergency braking
situation, the ABS operates to prevent the wheels locking. A
pulsating effect is felt through the brake pedal when this happens.
This is a normal effect of the ABS operating.
Two-Stage ABS
The ABS features two levels of calibration that change depending
on Electronic Stability Program (ESP) setting (Refer to 'ESP
Modes', page 5.22).
Safety
It is always the driver's responsibility to drive safely with regard to
driving conditions and according to the law. The fact that a
vehicle is equipped with ABS must never let the driver be
tempted into taking risks which could affect his or 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
aquaplaning (where the tires 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. Stopping distances can increase with
ABS compared to locked wheels on slushy snow, gravel, sand or
certain heavily corrugated or ridged warning sections of road
surfaces.
If any braking system malfunctions, have the braking and ABS
systems checked immediately by your Aston Martin Dealer.
