Mercedes-Benz SL-Class 2014 Owners Manual - Manual (Page 75)

When driving at a speed under 20 mph
(30 km/h): if you depress the brake pedal,
BAS PLUS is activated. The increase in brake
pressure will be carried out at the last
possible moment.
When driving at a speed above 20 mph
(30 km/h): if you depress the brake pedal
sharply, BAS PLUS automatically raises the
brake pressure to a value adapted to the
traffic situation.
BAS PLUS provides braking assistance in
hazardous situations with vehicles in front
within a speed range between 4 mph
(7 km/h) and 155 mph (250 km/h).
At speeds of up to approximately 40 mph
(70 km/h), BAS PLUS can also react to
stationary objects. Examples of stationary
objects are stopped or parked vehicles.
i If BAS PLUS demands particularly high
braking force, preventative passenger
protection measures (PRE-SAFE ® ) are
activated simultaneously.
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes
function as usual again, if:
R you release the brake pedal.
R there is no longer a risk of collision.
R no obstacle is detected in front of your
vehicle.
R you depress the accelerator pedal.
R you activate kickdown.
ESP ® (Electronic Stability Program)
General notes
i Observe the "Important safety notes"
section (
Y
page 70).
ESP ® monitors driving stability and traction,
i.e. power transmission between the tires and
the road surface.
If ESP ® detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. The engine output is also modified to
keep the vehicle on the desired course within
physical limits. ESP ® assists the driver when
pulling away on wet or slippery roads. ESP ®
can also stabilize the vehicle during braking.
ETS (Electronic Traction System)
i Observe the "Important safety notes"
section (
Y
page 70).
ETS traction control is part of ESP ® .
ETS brakes the drive wheels individually if
they spin. This enables you to pull away and
accelerate on slippery surfaces, for example
if the road surface is slippery on one side. In
addition, more drive torque is transferred to
the wheel or wheels with traction.
ETS remains active when you deactivate
ESP ® .
i AMG vehicles: your vehicle may be
equipped with 20-inch tires on the rear
axle. If replaced with a 19-inch tire, ETS
may intervene noticeably sooner for the
first few kilometers. After approximately
10 km ETS will function as usual again.
Information on the dimensions and types of
wheels and tires for your vehicle can be
found in the "Wheel/tire combinations"
section (
Y
page 602).
Important safety notes
G WARNING
If ESP ® is malfunctioning, ESP ® is unable to
stabilize the vehicle. Additionally, further
driving safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP
® checked at a
qualified specialist workshop.
! When testing the electric parking brake
on a braking dynamometer, switch off the
ignition. Application of the brakes by
