Warning!
The following factors increase the risk of
accidents:
Excessive speed, especially in turns
Wet and slippery road surfaces
Following another vehicle too closely
The ABS, BAS, ESP and 4-ETS cannot reduce
this risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.

Warning!
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.
The Antilock Brake System (ABS) regulates
the brake pressure so that the wheels do
not lock during braking. This allows you to
maintain the ability to steer your vehicle.
The ABS is functional above a speed of ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even with light brake pressure.
The - indicator lamp in the instrument
cluster ( page 25) comes on when you
turn the key in the steering lock to
position 2. It goes out when the engine is
running.
