94
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.
