Speed limits in wet conditions
:Maximum permitted speed
;Additional signs for wet conditions
A maximum permitted speed of 80 mph
(80 km/h) applies in wet conditions and if Traffic
Sign Assist has determined that the restriction
must be observed.
Canceling the speed limit
The speed limit no longer applies :.
iThe unit for the speed limit (km/h or mph)
depends on the country in which you are driv-
ing. It is generally neither shown on the traffic
sign nor on the instrument cluster but must be
taken into account when observing the max-
imum permitted speed.
Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist (Ypage 175) and Lane Keeping
Assist (Ypage 177).
Blind Spot Assist
General notes
Blind Spot Assist uses a radar sensor system to monitor the areas on both sides of your vehicle.
It supports you from a speed of approximately
20 mph (30 km/h). A warning display in the
exterior mirrors draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lanes, you will also receive an optical
and audible collision warning. Blind Spot Assist
uses sensors in the rear bumper for monitoring
purposes.
Important safety notes
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.

ing Assist is ready for use.
Standard
If Standardis selected, no warning vibration
occurs if:
Ryou have switched on the turn signals. In this
event, the warnings are suppressed for a cer-
tain period of time.
Ra driving safety system intervenes, such as
ABS, BAS or ESP®.
Adaptive
When Adaptiveis selected, no warning vibra-
tion occurs if:
Ryou have switched on the turn signals. In this
event, the warnings are suppressed for a cer-
tain period of time.
Ra driving safety system intervenes, e.g. ABS,
BAS or ESP®.
Ryou accelerate hard, e.g. kickdown.
Ryou brake hard.
Ryou steer actively, e.g. swerve to avoid an
obstacle or change lanes quickly.
Ryou cut the corner on a sharp bend.
In order that you are warned only when neces-
sary and in good time if you cross the lane mark-
ing, the system recognizes certain conditions
and warns you accordingly.
The warning vibration occurs earlier if:
Ryou approach the outer lane marking on a
bend.
Rthe road has very wide lanes, e.g. a highway.
Rthe system recognizes solid lane markings.
The warning vibration occurs later if:
Rthe road has narrow lanes.
Ryou cut the corner on a bend.
Active Driving Assistance package
General notes
The Active Driving Assistance package consists
of DISTRONIC PLUS (Ypage 147), Active Blind
Spot Assist (Ypage 178) and Active Lane Keep-
ing Assist (Ypage 181).
Active Blind Spot Assist
General notes
Active Blind Spot Assist uses a radar sensor
system, pointed toward the rear of the vehicle,
to monitor the area to the sides of the vehicle
which the driver is unable to see. A warning dis- play in the exterior mirrors draws your attention
to vehicles detected in the monitored area. If
you then switch on the corresponding turn sig-
nal to change lane, you will also receive an opti-
cal and audible warning. If a risk of lateral colli-
sion is detected, corrective braking may help
you avoid a collision. Before a course-correcting
brake application, Active Blind Spot Assist eval-
uates the space in the direction of travel and at
the sides of the vehicle. For this, Active Blind
Spot Assist uses the forward-facing radar sen-
sors.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
Important safety notes
Active Blind Spot Assist is only an aid and is not
a substitute for attentive driving.
GWARNING
Active Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is a risk of an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
