Blind Spot Assist General notes
Blind Spot Assist uses
aradar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from aspeed of
approximately 20 mph (30k m/h). Awarning
displa yinthe exterio rmirrors draws your
attention to vehicles detected in the
monitored area. If you the nswitc hont he
correspondin gturns ignal to change lanes,
you will also receive avisual and audible
collision warning. Blin dSpot Assist uses
sensors in the rear bumper for monitoring
purposes. For Blin
dSpot Assist to assist you, the radar
sensor system must be operational.
Important safety notes G
WARNING
Blin dSpot Assist does not reac tto:
R vehicles overtaken too closely on the side,
placin gthemint he blind spot area
R vehicles which approach with alarge speed
differential and overtake your vehicle
As aresult, Blind Spot Assist may not give
warnings in such situations. There is arisk of
an accident.
Always observe the traffic conditions
carefully, and maintain asafe 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.

Active Blind Spot Assist Genera
lnotes
Active Blind Spot Assis tuses aradar 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 displayint he exterior mirrors draws
your attention to vehicles detected in the
monitored area. If you then switch on the
corresponding turn signal to change lane, you
will also receive an optical and audible
warning. If arisk of lateral collision is
detected, corrective braking may help you
avoid acollision. Before acourse-correcting
brake application, Active Blind Spot Assist
evaluates the space in the direction of travel
and at the sides of the vehicle. For this, Active
Blind Spot Assist uses radar sensors which
are pointed in the direction of travel.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
