2014 MERCEDES-BENZ CLA ESP

Characteristics when ESP®is deactivated
If ESP®is deactivated and one or more wheels
start to spin, theESP®warning lamp in
the instrumentcluster does not flash. In such
situations, ESP®will not stabilize the vehicle.
If you deactivate ESP®:
RESP®no longer improves driving stability.
Rengine torque is no longer limited and the
drive wheels are able to spin.
The spinning of the wheels results in a
cutting action for better traction on loose
surfaces.
Rtraction control is still activated.
RPRE-SAFE®is no longer available, nor is it
activated if you brake firmly and ESP®
intervenes.
RCOLLISION PREVENTION ASSISTis no
longer available; nor is it activated if you
brake firmly with assistance from ESP®.

GWARNING
If you deactivate ESP®, ESP®no longer
stabilizes the vehicle. There is an increased
risk of skidding and an accident.
Only deactivate ESP®in the situations
described in the following.
It may be best to deactivate ESP®in the
following situations:
Rwhen using snow chains
Rin deep snow
Ron sand or gravel
iActivate ESP®as soon as the situations
described above no longer apply.ESP®will
otherwise not be able to stabilize the
vehicle if the vehicle starts to skid or a
wheel starts to spin.
!Avoid spinning the driven wheels for an
extended period with ESP®deactivated.
You could otherwise damage the drivetrain.

68Driving safety systems
Safety

ESP®trailer stabilization
General information
If your vehicle/trailer combinationbegins to
swerve, ESP®assists you in this situation.
ESP®slows the vehicle down by braking and
limiting the engine output until the vehicle/
trailer combination has stabilized.
Important safety notes
GWARNING
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 yourdriving style to the
prevailing road and weather conditions.
If yourvehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilize the vehicle/trailer combination by
depressing the brake firmly.
ESP®trailer stabilization is active above
speeds of about 40 mph (65 km/h).
ESP®trailer stabilization does not work if
ESP®is deactivated or disabled because of a
malfunction.
EBD (electronic brake force
distribution)
General information
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking.
Important safety notes
iObserve the "Important safety notes"
section for driving safety systems
(Ypage 61).
GWARNING
If EBDhas malfunctioned, the rear wheels can
still lock, e.g.underfull 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 (Ypage 242) as well as
display messages (Ypage 215).
ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In
addition to the braking function, ADAPTIVE
BRAKE also has the HOLD function
(Ypage 172) and hill start assist
(Ypage 138). For further information, see
Driving tips (Ypage 158).
STEER CONTROL
General information
STEER CONTROL helps you by transmitting a
noticeable steering force to the steering
wheel in the direction required for vehicle
stabilization.
This steering assistance is provided in
particular if:
Rboth right wheels or both left wheels are on
a wet or slippery road surface when you
brake.
Rthe vehicle starts to skid.
Important safety notes
If ESP®is malfunctioning, you will not receive
steering support from STEER CONTROL.
Power steering will, however, continue to
function.

Side window reversing feature
The side windows are equipped with an
automatic reversing feature. If a solid object
blocks or restricts a side window during the
closing process, the side window opens again
automatically. However, the automatic
reversing feature is only an aid and does not
relieve you of the responsibility of paying
attentionwhen closing a side window.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small
fingers
Rover the last 1/6 in(4 mm) of the closing
movement
Rduring resetting
Rwhen closing the side window again
manually immediately after automatic
reversing
This means that the reversing feature cannot
prevent someone being trapped in these
situations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure. If
someone becomes trapped, press the switch
to open the side window again.
Opening and closing the side

trapped in the closing area of the side window
and the sliding sunroof. There is a risk of
injury.
Observe the complete closing procedure
when the convenience closing feature is
operating. Make sure that no body parts are
in close proximity during the closing
procedure.
When you lock the vehicle, you can
simultaneously:
Rclose the side windows
Rclose the panorama roof with power tilt/
sliding panel
On vehicles with a panorama roof with power

If this is not the case, repeatthe steps
above again.
Problems with the side windows
GWARNING
If you close a side window again immediately
after it has been blocked or reset, the side
window closes with increased or maximum
force. The reversing feature is then not active.
Parts of the body could be trapped in the
closing area in the process. This poses an
increased risk of injury or even fatal injury.
Make sure that no parts of the body are in the
closing area. To stop the closing process,
release the switch or push the switch again to
reopen the side window.
Problem:aside window cannot be closed
because it is blocked by objects, e.g.
leaves in the window guide.

Panoramaroof with power tilt/sliding
panel
Important safety notes
In the following section, the term "sliding
sunroof" refers to the panorama roofwith
power tilt/sliding panel.
GWARNING
While opening and closing the sliding sunroof,
body parts in close proximity could become
trapped. There is a risk of injury.
Make sure that no body parts are in close
proximity during the opening and closing
procedures.
If somebody becomes trapped:
Rrelease the switch immediately, or
Rduring automatic operation, push the
switch briefly in any direction
The opening or closing procedure will be
stopped.
GWARNING
If children operate the sliding sunroof they
could become trapped, particularly if they are
left unsupervised. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
GWARNING

immediately, paying attention to road and
traffic conditions.The sliding sunroof opens
again to its original position.
If the sliding sunroof is not completely raised,
you can then raise it further with the switch.
!Only open the sliding sunroof if it is free
of snow and ice. Otherwise, malfunctions
may occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could
be damaged.

sliding sunroof is closed when you leave the
vehicle. The vehicle electronics can be
damaged if water enters the vehicle
interior.
iResonance noises can occur in addition
to the usual airflow noises when the sliding
sunroof is open. They are caused by minor
pressure fluctuations in the vehicle interior.
Change the position of the sliding sunroof
or open a side window slightly to reduce or
eliminate these noises.
