The limit speed set
bythe 1st pressure point is
shown in the speedome ter.The segments
between the cur rently driven speed and the limit

small deviations between the cur rently driven
speed and the limit speed are permitted.
If yo ustep on the accelera tor pedal be yond the
1st pressu repoint, the limit speed is deactiva‐
te d. The green segments in the speedome ter are
not shown. When the accelera tor pedal is posi‐
tioned in front of the 1st pressure point again,
th e limit speed is reactivated, thus making sure
th at the maximum permissible speed is main‐
ta ined again.
If a vehicle in front is de tected, the speed is
re duced in order tofollow theve hicle in front at
an adjus ted dis tance.
If th eve hicle de tects road and traf fic conditions

ge r driven and coasts. Todecelerate theve hicle,
re lease the accelerator pedal. How much the
ve hicle automatically decelerates when the
accelerator pedal is released depends on the set
re cuperation le vel (/ page 150). In hÃ,
deceleration is auto matic wherethere are vehi‐ cles in front, traf
fic signs, roundabouts and
bends. In all other recuperation le vels, a perma‐
nently defined overrunto rque is se t. Ifthe situa‐
tion calls for it, you must also depress the brake
pedal rega rdless of the selected recuperation
le ve l.
If yo u activate theAc tive Dis tance Assi st
DISTRONIC or the cruise control in drive pro‐
gram Í, the limit speed is deactivated bythe
1st pressu repoint. If you deactivate the function
again, the limit speed set bythe pressure point
is switched on again.
If yo u also activate the limiter in drive program
Í, the speed is limited byboth Í andthe
limiter:
R ifth e speed stored in the limiter is higher
th an the limit speed of Í,theve hicle
accelerates up tothe speed stored in the lim‐
iter when you depress the accelera tor pedal
be yond the 1st pressure point. If you depress
th e accelerator pedal be yond the 2nd pres‐
sure point (kickdown), theve hicle continues
to accelerate without any limitation. R
ifth e speed stored bythe limiter is lo wer
th an or equal tothe limit speed of Í,then
th e speed is limited byboth th e 1st and the
2nd pressu repoints tothe speed stored by
th e limiter. If you depress the accelera tor
pedal be yond the 2nd pressure point (kick‐
down), theve hicle continues toaccelerate
without any limitation.

nction of flexible all-wheel distribution
The flex ible all-wheel distribution means the
drive is alw ays ideally distributed between the
two axles. Depending on the situation, only the
front axle or only there ar axle can be driven, or
th e drive can be distributed continuously
between bo thaxles.
This allo ws the maximum recur rent delay tobe
achie ved (/ page149). The resulting recupera‐
tion increases theve hicle's range.
To get her with ESP ®
and 4ETS, theflex ible all-
wheel distribution impr ovesth e traction of your
ve hicle whene ver a driven wheel spins due to
insuf ficient traction.
If yo ufa ilto adapt your driving style, theflex ible
all-wheel distribution can neither reduce therisk
of accident nor override the la wsof ph ysics. It
cannot take into account road, weather or traf fic
conditions. The flex ible all-wheel distribution is only an aid.
You are responsible especially for
maintaining a safe dis tance from theve hicle in
front, forve hicle speed, for braking in good time
and forst ay ing in lane.
% In wint ryroad conditions, the maximum
ef fect of theflex ible all-wheel distribution
can be achie ved only if you use winter tyres
