MERCEDES-BENZ SLK55AMG 2011 R170 Workshop Manual

G
Warning!
If the ABS malfunctions, other driving safety
systems such as the BAS or the ESP ®
are also
switched off. Observe indicator and warning
lamps that may come on as well as messages
in the multifunction display that may appear.
If the ABS malfunctions, the wheels may lock
during hard braking, reducing steering
capability and extending the braking distance. BAS
G
Observe Safety notes, see page 48.
The Brake Assist System (BAS) operates in
emergency
situations. If you apply the brakes
very quickly, the BAS provides full brake
boost automatically, thereby potentially
reducing the braking distance.
X Apply continuous full braking pressure until
the emergency braking situation is over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the brakes
function again as normal. The BAS is then
deactivated. G
Warning!
If the BAS malfunctions, the brake system still
functions, but without the additional brake
boost available that the BAS would normally
provide in an emergency braking maneuver.
Therefore,

the braking distance may increase. ESP
® G
Observe Safety notes, see page 48.
The Electronic Stability Program (ESP ®
) is
operational
as soon as the engine is running.
It monitors the vehicle’s traction (force of
adhesive friction between the tires and the
road surface) and handling.
The ESP ®
recognizes that the vehicle deviates
from the direction of travel as intended by the
driver. By applying brakes to individual wheels and by limiting the engine output, the
ESP
®
works to stabilize the vehicle. The
ESP ®


is especially useful while driving off and
on wet or slippery road surfaces. The ESP ®
also stabilizes the vehicle during braking and
steering maneuvers.
The ESP ®
warning lamp d in the
instrument cluster comes on when you switch
on the ignition. It goes out when the engine
is running.
The ESP ®
warning lamp d in the
instrument cluster flashes when the ESP ®
is
engaged. G
Warning!
Never switch off the ESP ®
when you see the
ESP ®
warning lamp d flashing in the
instrument cluster. In this case proceed as
follows:
R When driving off, apply as little throttle as
possible.
R While driving, ease up on the accelerator
pedal.
R Adapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid. The ESP ®
cannot
prevent accidents resulting from excessive
speed.
! Because the ESP ®
operates
automatically,

the engine and ignition must
be shut off (SmartKey in starter switch
position 0 or 1) when the parking brake is
being tested on a brake test dynamometer
or when the vehicle is being towed with the
front axle raised.
Active braking action through the ESP ®
may otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.
! The ESP ®
will only function properly if you
use wheels of the recommended tire size Driving safety systems

as specified in the “Technical data” section
of this Operator’s Manual.
i The cruise control switches off
automatically when the ESP ®
engages.
Electronic Traction System (ETS) G
Observe Safety notes, see page 48.
The ETS (Electronic Traction System) is a
component of the ESP ®
. The ETS improves
the vehicle’s ability to utilize available
traction, especially under slippery road
conditions by applying the brakes to a
spinning wheel.
When you switch off the ESP ®
, the ETS is still
enabled.
Switching off the ESP ®G
Warning!
The ESP ®
should not be switched off during
normal driving other than in the
circumstances described below. Disabling
the system will reduce vehicle stability in
driving maneuvers.
Do not switch off the ESP ®
when a spare
wheel is mounted.
To improve the vehicle’s traction, switch off
the ESP ®
. This allows the drive wheels to spin
and thus cut into surfaces for better grip, for
example
R when driving with snow chains
R in deep snow
R in sand or gravel G
Warning!
Switch on the ESP ®
immediately if the
aforementioned circumstances do not apply
anymore. Otherwise the ESP ®
will not
stabilize the vehicle when it is starting to skid
or a wheel is spinning. When you switch off the ESP
®
,
R the ESP ®
does not stabilize the vehicle
R the engine output is not limited, which
allows the drive wheels to spin and thus cut
into surfaces for better grip
R the ETS will still apply the brakes to a
spinning wheel
R the ESP ®
continues to operate when you
are braking
R the cruise control cannot be activated
R the cruise control switches off if activated
i When the ESP ®
is switched off and one or
more drive wheels are spinning, the ESP ®
warning lamp d in the instrument
cluster flashes. However, the ESP ®
will
then not stabilize the vehicle. X
With the engine running, press ESP ®
switch : until the ESP ®
warning lamp
d in the instrument cluster comes on.
The ESP ®
is switched off. G
Warning!
When the ESP ®
warning lamp d is
illuminated continuously, the ESP ®
is
switched off or is not operational due to a
malfunction. Vehicle stability in standard
driving maneuvers is reduced.
Adapt your speed and driving to the prevailing
road conditions and to the non-operating
status of the ESP ®
. 50
