controlled manner. The spinning of the
wheels results in a cutting action, which
provides better grip.
R ESP ® still provides support when you
brake.
Characteristics when ESP ® is deactivated
If ESP ® is deactivated and one or more wheels
start to spin, the ÷ ESP ® warning lamp in
the instrument cluster does not flash. In such
situations, ESP ® will not stabilize the vehicle.
If you deactivate ESP ® :
R ESP ® no longer improves driving stability.
R the engine's torque is no longer limited and
the drive wheels are able to spin without
restriction. The spinning of the wheels
results in a cutting action, which provides
better grip.
R traction control is still activated.
R PRE-SAFE ® Brake is no longer available;
nor is it activated if you brake with
assistance from ESP ® .
R ESP ® still provides support when you
brake.
ESP ® trailer stabilization
G WARNING
If road and weather conditions are poor,
trailer stabilization will not be able to prevent
the vehicle/trailer combination from
swerving. Trailers with a high center of gravity
can tip over before ESP
® can detect this.
There is a risk of an accident.
Always adapt your driving style to the
prevailing road and weather conditions.
If your vehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilize the vehicle/trailer combination by
depressing the brake firmly.
In this situation, ESP
® assists you and can
detect if the vehicle/trailer combination
begins to lurch. ESP ® slows the vehicle down
by braking and limiting the engine output until
the vehicle/trailer combination has
stabilized.
Trailer stabilization is active above speeds of
about 40 mph (65 km/h).
Trailer stabilization does not work if ESP
® is
deactivated because of a malfunction.
EBD (electronic brake force
distribution)
i Observe the "Important safety notes"
section (
Y
page 64).
G WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This
increases the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified
specialist workshop.
Observe information regarding indicator and
warning lamps (
Y
page 259) as well as
display messages (
Y
page 233).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking.
PRE-SAFE ® Brake
i Observe the "Important safety notes"
section (
Y
page 64).
PRE-SAFE ® Brake is only available in vehicles
with DISTRONIC PLUS.
If PRE-SAFE
® Brake is to aid you, the radar
sensor system must be:
R activated (
Y
page 229)
R operational
With the help of the radar sensor system,
PRE-SAFE ® Brake can detect obstacles that
are in front of your vehicle for an extended
period of time.
PRE-SAFE
® Brake can help you to minimize
the risk of a collision with a vehicle ahead or
