Emergency brake MERCEDES-BENZ C-Class 2000 W202 Owner's Manual

Brake Assist System (BAS)

Warning !

BAS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking
efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction afforded.
The BAS cannot prevent accidents, including those resulting from excessive speed in turns, following
another vehicle too closely, or aquaplaning. Only a safe, attentive, and skillful driver can prevent accidents.
The capabilities of a BAS equipped car must never be exploited in a reckless or dangerous manner which
could jeopardize the user's safety or the safety of others.

The Brake Assist System is designed to maximize the vehicle's braking capability during emergency braking
maneuvers by having maximum power boost applied to the br akes more quickly in emergency braking conditions
than might otherwise be afforded solely by the driver's braking style. This can help reduce braking distances over
what ordinary driving and braking style might do. The BAS complements the Antilock Brake System (ABS).
To receive the benefit of the system you must apply continuous full braking power during the stopping sequence.
Do not reduce brake pedal pressure.
Once the brake pedal is released, the BAS is deactivat ed The malfunction indicator lamps for the ASR and ESP are
combined with the BAS malfunction indicator lamp.
The BAS/ASR or BAS/ESP malfunction indicator lamp in the instrument cluster come on with the electronic key in
steering lock position 2 and should go out with the engine running.
If the BAS/ASR or BAS/ESP malfunction indicator lamp comes on permanently while the engine is running,
a malfunction has been detected in either system. As a resul t, it is possible that now only partial engine output will be
available, and pressing the accelerator pedal will require more effort. If the BAS malfunctions. The brake system
functions in the usual manner, but wi thout BAS. If the charging voltage falls be low 10 volts, the malfunction indicator
lamp comes on and the BAS is switched off. When the volt age is above this value again, the malfunction indicator
lamp should go out and the BAS is operational. With t he ABS malfunctioning, the BAS, ASR or ESP are also
switched off.
Both malfunction indicator lamps come on with the engine running. Have the BAS, ASR or ESP checked at your
authorized Mercedes-Benz dealer as soon as possible .
