Ac tive Tra1c Jam Assist helps you when in tra1c
jams on multi-lane roads with separate car riage-
wa ys by automatically pulling away within 60 sec-
onds and with mode rate stee ring manoeuvres. It
orients itself using theve hicle in front and lane
markings. Active Tra1c Jam Assist automatically
main tains a safe distance from theve hicle in front
and vehicles cutting in.
Ac tive Tra1c Jam Assist requ ires you, as the
driver, tokeep your hands on the steering wheel
at all times so that you are able tointer vene at
any time tocor rect the course of theve hicle and
ke ep it in lane. Obser vethe no tes on driving sys- te
ms and your responsibility; you may otherwise
fa ilto recognise dangers (/ page 183).
Ac tive Tra1c Jam Assist activates automatically as
soon as all of there qu irements are met: The ¬
