Regulation) Note
s on DSR If
yo ufa ilto adapt your driving style or you are
inat tentive, DSR can nei ther reduce therisk of
accident nor override the la wsof ph ysics. DSR
cannot take road, weather and traf fic conditions
into account. DSR is only an aid. You are respon‐
sible for a safe dis tancetotheve hicle in front, for
ve hicle speed and for braking in good time.
DSR supports you when driving downhill. DSR
main tains a set speed foryo u on downhill gradi‐
ents byapplying the brakes as required. Main‐
ta ining the speed is dependent on thero ad sur‐
fa ce conditions and the downhill gradient and
cann ottherefore be guaranteed in all situations.
Yo u can set the speed depending on thege ar
ra nge tobetween 2 mph (4 km/h) and 11mph
(18 km/h) using the brake and accelera tor pedals
or therock er switch on thesteering wheel.
DSR automatically cont rols in thefo llowing situa‐
tions:
R Ifth eve hicle is stationar y,or its speed is less
th an 2 mph (4 km/h) , the speed is set to
2 mp h (4 km/h) or it is set tothe minimum
speed forth ere spective gear range.
R Ifyo u drive fasterthan 11mp h (18 km/h) off-
ro ad, DSR swit ches tostandby mode. DSR
re mains activated, but does not brake auto‐
matical ly.
R Ifyo u drive downhill slo werth an 11mph

ously set speed. R

The cur rent speed is stored. When stationar y,
2 mp h (4 km/h) or the minimum possible
speed for each gear range is stored. DSR
maintains thestored speed on the downhill
