Traffic Sign Assist
General notes
Traffic Sign Assist displays the maximum speedpermitted to the driver in the instrument cluster.The data and general traffic regulations stored inthe navigation system are used to determine thecurrent speed limit.
Traffic Sign Assist is a map-based system, andfor this reason, traffic signs put up temporarily(e.g. near roadworks) are not detected. There isalso no display for changing traffic signs.
Traffic signs with a restriction indicated by anadditional sign (e.g. in wet conditions) are alsoshown.
The sign indicating the end of a restriction onlyappears with the restriction in the instrumentcluster when:
RThe regulation must be observed with therestriction, or
RTraffic Sign Assist is unable to determinewhether the restriction applies
If Traffic Sign Assist is unable to determine amaximum permitted speed from any of the avail-able sources, no speed limit appears in theinstrument cluster either.
Traffic Sign Assist is not available in all coun-tries. In this case, displayCappears in theassistance graphic (Ypage 219).
Important safety notes
Traffic Sign Assist is only an aid and is not alwaysable to correctly display speed limits. Trafficsigns always have priority over the Traffic SignAssist display.
The system may be either functionally impairedor temporarily unavailable if the information inthe digital street map of the navigation system isincorrect or out of date.

GWARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist.
Lane Keeping Assist can neither reduce the riskof an accident if you fail to adapt your drivingstyle nor override the laws of physics. LaneKeeping Assist cannot take into account theroad, traffic and weather conditions. Lane Keep-ing Assist is merely an aid. You are responsiblefor the distance to the vehicle in front, for vehi-cle speed, for braking in good time and for stay-ing in your lane.
The Lane Keeping Assist does not keep the vehi-cle in the lane.
The system may be impaired or may not functionif:
Rthere is poor visibility, e.g. due to insufficientillumination of the road, or due to snow, rain,fog or heavy spray
Rthere is glare, e.g. from oncoming traffic, thesun or reflection from other vehicles (e.g. ifthe road surface is wet)
Rthe windshield is dirty, fogged up, damaged orcovered, for instance by a sticker, in the vicin-ity of the camera
Rthere are no or several unclear lane markingsfor one lane, e.g. roadworks
Rthe lane markings are worn away, dark or cov-ered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too shortand thus the lane markings cannot be detec-ted

Course-correcting brake application
If Active Blind Spot Assist detects a risk of a lat-eral collision in the monitoring range, a course-correcting brake application is carried out. Thisis meant to assist you in avoiding a collision.
GWARNING
A course-correcting brake application cannot
always prevent a collision. There is a risk of an
accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake appli-
cation. Always maintain a safe distance at the
sides.
If a course-correcting brake application occurs,red warning lampCflashes in the exterior mir-ror and a double warning tone sounds. In addi-tion, a display underlining the danger of a sidecollision appears in the multifunction display.
In very rare cases, the system may make aninappropriate brake application. A course-cor-recting brake application may be interrupted atany time by countersteering slightly or acceler-ating.
The course-correcting brake application is avail-able in the speed range between 20 mph(30 km/h) and 120 mph (200 km/h).

Towing a trailer
Important safety notes
GWARNING
Installing an unsuitable ball coupling may
result in overloading of the trailer tow hitch
and the rear axle. This applies especially if the
ball coupling in question is longer or angled
differently. This could seriously impair the
driving characteristics and the trailer can
come loose. There is a risk of an accident.
You should only ever install a ball coupling
that has the permissible dimensions and that
is designed to meet your trailer-towing
requirements. Do not modify the ball coupling
or the trailer tow hitch.
You will find the values approved by the manu-facturer on the vehicle identification plates andthose for the towing vehicle under "Technicaldata" (Ypage 364).
GWARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi-
cle/trailer combination could even rollover.
There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
!If you have a trailer tow hitch retrofitted,changes to the engine cooling system may benecessary, depending on the vehicle type.
If you have a trailer tow hitch retrofitted,observe the anchorage points on the chassisframe.
The installation of a trailer tow hitch is only per-missible if a towing weight is specified in yourvehicle documents. If this is not the case, thenthe vehicle is not approved for the towing of atrailer.
