The speed limit no longer applies :.
i
The 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 (
Y page 187) and Lane Keeping
Assist (
Y page 189).
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
G
WARNING
Blind Spot Assist does not react to:
R
vehicles overtaken too closely on the side,
placing them in the blind spot area
R
vehicles 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.

R
there is poor visibility, e.g. due to fog, heavy
rain, snow or spray
