G12￿Driver￿Assistance￿Systems
17.￿Cross-Traffic￿Warning
The￿cross-traffic￿warning￿is￿used￿for￿the￿first￿time￿in￿the￿G12.￿This￿warning￿assists￿the￿driver￿when
maneuvering￿out￿of￿a￿parking￿space￿and￿in￿other￿everyday￿situations￿where￿it￿is￿difficult￿to￿see￿the
traffic,￿such￿as￿at￿blind￿entrances￿and￿exits.
Depending￿on￿the￿vehicle￿equipment,￿the￿cross-traffic￿warning￿is￿available￿for￿the￿front￿and￿rear.
The￿system￿can￿detect￿objects￿that￿are￿approaching￿the￿vehicle￿from￿the￿side,￿either￿from￿the￿front￿or
rear￿(depending￿on￿the￿vehicle￿equipment).￿The￿driver￿is￿made￿aware￿or,￿if￿necessary,￿warned￿of￿cross
traffic￿by￿the￿cross-traffic￿warning￿when￿maneuvering￿out￿of￿a￿parking￿space￿or￿entering￿the￿cross
traffic.
17.1.￿Functional￿principle
If￿a￿moving￿object￿is￿detected,￿which￿based￿on￿the￿current￿speed￿would￿be￿in￿the￿area￿in￿front￿of￿or
behind￿the￿vehicle￿in￿approximately￿the￿next￿three￿seconds,￿a￿visual￿and￿acoustic￿warning￿is￿issued.
When￿a￿rear￿cross-traffic￿warning￿is￿issued,￿the￿LED￿in￿the￿mirror￿glass￿is￿also￿switched￿on.￿The￿Blind
spot￿detection￿signal￿unit￿is￿used￿as￿an￿indicator.￿The￿indicator￿is￿switched￿on￿in￿either￿the￿left￿or￿right
mirror￿depending￿on￿the￿direction￿from￿which￿the￿object￿is￿approaching￿the￿vehicle.
The￿cross-traffic￿warning￿works￿up￿to￿a￿speed￿of￿approximately￿7 km/h.￿Another￿prerequisite￿of￿the
function￿is￿that￿the￿side￿radar￿sensors￿are￿able￿to￿detect￿the￿road￿or￿approaching￿object.￿The￿radar
sensors￿can￿detect￿objects￿up￿to￿approximately￿30￿to￿40 m￿away￿from￿the￿vehicle.
G12￿cross-traffic￿warning￿example:￿maneuvering￿out￿of￿a￿parking￿space
Depending￿on￿the￿vehicle￿equipment,￿different￿versions￿of￿the￿cross-traffic￿warning￿and￿displays￿on
the￿central￿information￿display￿are￿available.
