R Road users without lights, e.g. pedes‐
trians
R Road users with poor lighting, e.g.
cyclists R
Road users whose lighting is obstructed,
e.g. bya bar rier
In very rare cases, Adaptive Highbeam Assist
Plus may not recognise road users who do
ha ve lights, or may recognise them too late.
In this, or in similar situations, the automatic
main beam will not be deactivated or will be
activated despite the presence of other road
users. #

R During braking, e.g. at maximum full-s top
braking or insuf ficient traction of the tyres,
th e wheels are pr evented from blocking.
R Vehicle steerability while braking is ensured.
If ABS inter venes when braking, you will feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road

emergency braking situation:
R Byflashing brake lamps
R By activating the hazard warning lights
If th eve hicle is braked sharply from speeds
abo ve50 km/h, the brake lamps flash rapidly.
This pr ovides traf fic tr ave lling behind you with an
eve n more noticeable warning.
If th eve hicle is tr avelling at speeds of more than
70 km/h at the beginning of the brake applica‐
tion, the hazard warning lights switch on once
th eve hicle is stationar y.When pulling away
again, the hazard warning lights switch off auto‐
matically at appr oximately 10km/h. You can
also swit choff the hazard warning lights using
th e hazard warning button. Cruise control and limiter
Fu
nction of cruise control
Cruise cont rol accelerates and brakes theve hi‐
cle automatically in order tomaintain a pr evi‐
ously stored speed. If
yo u accelerate to overtake ,fo rex ample, the
st ored speed is not dele ted. If youre mo veyour
fo ot from the accelerator pedal af terove rtaking,
cruise control will resume speed regulation back
to thestored speed.
Yo u can operate cruise cont rol with the cruise
control le ver.
If yo ufa ilto adapt your driving style, cruise con‐
trol can neither reduce therisk of an accident
nor override the la wsof ph ysics. It cannot take
into account road, weather or traf fic conditions.
Cruise control is only an aid. You are responsible
fo rth e dis tance totheve hicle in front, forve hi‐
cle speed, for braking in good time and forst ay‐
ing in lane.
Sy stem limitations
Cruise control may be unable tomaintain the
st ored speed on uphill gradients. The stored
speed is resumed when the gradient evens out.
Change into a lo werge ar in good time on long
and steep downhill gradients. Take particular
no te ofthis when driving a laden vehicle. By
doing so, you will make use of the braking ef fect
of the engine. This relie vesth e load on the brake sy
stem and pr events the brakes from overheat‐
ing and wearing tooqu ickl y.
Do not use cruise control in thefo llowing situa‐
tions:
R In traf fic situations whi chrequ ire frequent
ch anges of speed, e.g. in heavy traf fic, on
winding roads
R On slippe ryroads. Accelerating can cause
th e drive wheels tolose traction and the
ve hicle could then skid
R When visibility is poor
Fu nction of the limi ter
The limiter restricts the speed of theve hicle. To
re duce the speed swiftly tothe set speed, the
limiter applies the brakes automaticall y.
Yo u can limit the speed as follo ws:
R Variable: for speed limits, e.g. in built-up
areas.
R Perm anen t:for long-term speed restrictions,
e.g. when driving wi thwinter tyres fitted.
If yo ufa ilto adapt your driving style, the limiter
