General notes
Active Lane Keeping Assist monitors the area
in front of your vehicle by means of a cam-
era
:at the top of the windscreen. Active
Lane Keeping Assist detects lane markings on
the road and warns you before you leave your
lane unintentionally. If you do not react to the
warning, a lane-correcting application of the
brakes can bring the vehicle back into the
original lane.
If you have chosen the function Displayunit Speed-/odometer: (Y
page 242) in
the on-board computer and selected km as
the unit of measurement, Active Lane Keep-
ing Assist is active from speeds of 60 km/h.
If the Miles display unit is selected, the assis-
tance range begins at 40 mph.
Warning vibration in the steering wheel
A warning may be given if a front wheel
passes over a lane marking. It will warn you
by means of intermittent vibration in the
steering wheel for up to 1.5 seconds.
In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system recognises certain con-
ditions and warns you accordingly.
The warning vibration occurs earlier if:
R you approach the outer lane marking on a
bend.
R the road has very wide lanes, e.g. a motor-
way.
R the system recognises solid lane markings. The warning vibration occurs later if:
R
the road has narrow lanes.
R you cut the corner on a bend.
Lane-correcting brake application G
WARNING
Active Lane Keeping Assist does not keep
yourv ehicle in its lane. It is only an aid
designed to assist driving. It is not a substitute
for attentive driving. Corrective braking may
not always be sufficien tto return your vehicle
to its original lane. In such cases, you must
steer the vehicle yourself to ensure that it
does not leave the lane.
Active Lane Keeping Assist cannot detect the
current traffic situation or other road users.
Ensure at all times that there is sufficient lat-
eral distance between you and other road
users or obstacles. In rare cases, broken lines
or certain structures on the road surface may
be detected by the system as solid lane mark-
ings. You can, for example, countersteer gen-
tly at any time to cancel inappropriate braking
action, e.g. if you intentionally drive across a
solid lane marking.
Active Lane Keeping Assist cannot take
weather conditions into account.
You are responsible for the vehicle's speed,
correc tsteering and for braking in good time.
Always adap tyour driving style to suit the
prevailing road and weather conditions.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others. Example: vehicles with automatic transmission218

If a lane-correcting brake application occurs,
the display shown in the illustration appears
in the multifunction display.
If you leave your lane under certain circum-
stances, the vehicle will brake briefly on one
side. This is designed to help you bring the
vehicle back into the original lane.
This function is available in the range between
60 km/h and 200 km/h.
A lane-correcting brake application can only
be made after driving over a solid, recognis-
able lane marking. Before this, a warning
must be emitted by means of intermittent
vibration in the steering wheel. In addition, a
lane with lane markings on both sides must
be recognised. The brake application also
slightly reduces driving speed.
i A further lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane.
No lane-correcting brake application occurs
if:
R you clearly and actively steer, brake, or
accelerate.
R you cut the corner on a sharp bend.
R you have switched on the turn signals.
R a driving safety system intervenes, such as
ESP ®
, PRE-SAFE ®
Brake or Active Blind
Spot Assist.

high cornering speeds or high rates of
acceleration.

electrical connection to the trailer has been
correctly established.
R ESP ®
is deactivated.
R the transmission is not in position D.

road and traffic conditions. An inappropriate
brake application may be interrupted at any
time if:

you steer slightly in the opposite direction.
R you use a turn signal.
R you clearly brake or accelerate.
Al ane-correcting brake applicatio nis inter-
rupted automatically if:
