Cross Traffic Alert*
CTA 86
is a supplementary driver support system
to BLIS 87
that is intended to help the driver
detect vehicles crossing behind the vehicle
while backing up. CTA overview.
CTA supplements BLIS by detecting traffic cross-
ing from the side, e.g. when backing out of a
parking space.
CTA is primarily designed to detect vehicles, but
in certain cases can also detect pedestrians or
smaller objects such as bicycles.
CTA is only active when the vehicle is moving
backward or if reverse gear is engaged. If CTA detects that something is approaching
your vehicle from the side:
• an audible signal will sound from either the
left or right speaker, depending on which
side of your vehicle the object is approaching
from.
• an icon will illuminate in the PAS 88
graphic
on the screen.
• an icon will appear in the Park Assist Cam-
era's Top view. Illuminated CTA icon in the PAS
88
graphic 89
on the
screen.
WARNING •
The Cross Traffic Alert function is supple-
mentary driver support intended to facili-
tate driving and make it safer – it cannot
handle all situations in all traffic, weather
and road conditions.
• The responsibility for reversing the vehicle
safely and using good judgment always
rests with the driver.
• Cross Traffic Alert is not a substitute for
the driver's attention and judgment. The
driver is always responsible for ensuring
the vehicle is driven in a safe manner, at
the appropriate speed, with an appropri-
ate distance to other vehicles, and in
accordance with current traffic rules and
regulations.

CTA 91
functionality may be reduced in certain
situations.
CTA does not function optimally in all situations
and has certain limitations. The CTA sensors, for
example, cannot "see" through other parked
vehicles or objects blocking the vehicle.
Below are a few examples of situations in which
CTA's field of vision may be initially limited and
approaching vehicles may therefore not be
detected until they are very close to your vehicle: The vehicle is parked very far into a parking space. In a diagonal parking space, CTA may be completely
"blind" on one side of your vehicle.

CTA's field of vision.
However, as you back your vehicle slowly out of a
parking space, CTA's field of vision changes in
relation to the obstructing vehicle/object and its
blind zone is reduced. 90

Examples of further limitations
•Dirt, ice and snow covering the sensors may
reduce functionality and prevent the system
from providing warnings. For additional infor-
mation, see the section "Recommended
maintenance for Cross Traffic Alert".
• CTA is automatically deactivated if a trailer,
bicycle holder or similar is connected to the
vehicle's electrical system.
• For CTA to function optimally, bicycle hold-
ers, luggage racks or similar should not be
mounted on the vehicle's towbar.
