Mercedes-Benz E 320 Wagon 1999 ASR - Manual

101
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 aqua-
planing. Only a safe, attentive, and
skillful driver can prevent accidents.
The capabilities of a BAS equipped
vehicle must never be exploited in a
reckless or dangerous manner which
could jeopardize the user's safety or
the safety of others.
The BAS is designed to maximize the
vehicle's braking capability during
emergency braking maneuvers by
having maximum power boost applied
to the brakes 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 deactivated
The malfunction indicator lamps for
the ASR or ESP are combined with the
BAS malfunction indicator lamp.
The BAS/ASR or BAS/ESP
malfunction indicator lamp in the
instrument cluster comes 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 result, 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 without BAS.
If the charging voltage falls below 10
volts, the malfunction indicator lamp
comes on and the BAS is switched off.
When the voltage is above this value
again, the malfunction indicator lamp
should go out and the BAS is
operational.
With the 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.
