aptive Brake Lights warnfollowing traf fic in an
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,

Pe rm anent limi ter
If yo u wish tolimit theve hicle speed perma‐

te r tyres), you can set this speed with the per‐
manent limiter.
Yo u do this by limiting the speed toava lue
between 160 km/h and 240 km/h in the multi‐
media sy stem (→ page180).
Shortly before the set speed is reached, it
appears in the multifunction displa y.When you

nction of Steering Pilot
Ste ering Pilot is only available forve hicles
with the Driving Assistance Package.
R Steering Pilot is operational at speeds up to
21 0 km/h and helps youto stay inthe cent re
of the lane bymeans of moderate steering
inter ventions. R
It uses theve hicle in front and the lane mark‐
ings as a refere nce depending on the driven
speed.
R Steering Pilot requ ires you as the driver, to
ke ep your hands on thesteering 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.
R Steering Pilot can be overridden at any time
by steering theve hicle yourself.
R When the sy stem is actively steering, the
è symbol is shown in green in the multi‐
function displa y.
Sy stem limitations of Steering Pilot
St eering Pilot has a limited steering torque for
lateral guidance. In some cases, thesteering
inter vention is not su fficient tokeep theve hicle
in the lane.
If de tection of lane markings and vehicles ahead
is impaired, Steering Pilot switches topassive
mode. The sy stem pr ovides no support in this
case. During the transition from the active to
passive status, theè symbol is shown as
enlar ged and flashes yello w. Once the sy stem is passive
theè symbol is shown as gr eyinthe
multifunction displa y.
The sy stem may be impaired or may not function
in thefo llowing ins tances:
R Ifth ere is poor visibility, e.g. due toinsuf fi‐
cient illumination of thero ad, or due tosno w,

R Ifth ere is glare, e.g. from oncoming traf fic,
