Ac tive Brake Assi stcan help youto minimise the

If Ac tive Brake Assi sthas de tected a risk of colli‐
sion, a warning tone sounds and theL warn‐

If yo u do not react tothewa rning, autonomous
braking can be initiated in critical situations. In
especially critical situations, Active Brake Assi st
can initiate auto nomous braking dire ctly.In this
case, thewa rning lamp and warning tone occur
simul taneously wi th the braking application.
If yo u apply the brake yourself in a situation
de tected as critical byActive Brake Assi st, or
apply the brake during autonomous braking, sit‐
uation-dependent brake forc e boosting occurs.
The brake pressure increases up tomaximum
full-s top braking if necessar y. If autonomous braking or a situation-dependent
braking boosting ef

R By activating the hazard warning lights
If th eve hicle is braked sharply from speeds
abo ve50 km/h, the brake lamps flash rapidl y.
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 the
ve hicle is stationar y.When pulling away again,
th e hazard warning lights switch off automatically
at appr oximately 10km/h.
Yo u can also swit choff the hazard warning lights
using the hazard warning button (/ page107). Cruise control and limiter
Fu
nction of cruise control
Cruise cont rol accelerates and brakes theve hicle
automatically in order tomaintain a pr eviously
st ored speed.
If yo u accelerate toove rtake, forex 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 operate cruise control using the cruise con‐
trol le ver.Yo u can store any speed abo ve
30 km/h.
Obser vethe no tes on driving sy stems and your
re sponsibility; you may otherwise failto recog‐
nise dangers (/ page 153). Sy
stem limits
Cruise control may be unable tomaintain the
st ored speed on uphill gradients. The stored
speed is resumed if the uphill gradient evens out
and theve hicle's speed does not fall below
30 km/h.
On long and steep downhill gradients, you should
ch ange down toa lo werge ar in good time. Take
particular no teofthis when driving a laden vehi‐
cle. By doing so, you will make use of the
engine's braking ef fect. This will take some of the
st ra in off the brake sy stem and pr eventthe
brakes from overheating and wearing tooqu ickl y.
If yo uch ange wheel size on your vehicle, check it
is assigned tothe cor rect wheel size catego ry
( / page 258). If the category is changed without
re coding the cont rol units in theve hicle, the func‐
tioning of cruise cont rol may be impaired.
Do not use cruise control in thefo llowing situa‐
tions:
R in traf fic situations whe refrequent speed
ch anges are required, e.g. in heavy traf fic or
on winding roads
R off-road or on con stru ction sites
R on slippe ryor slick roads, as the drive wheels
can lose traction when accelerating and the
ve hicle can then skid
R ifth ere is poor visibility
Fu nction of the limiter
The limiter restricts the speed of theve hicle. To
adjust tothe set speed quickl y,the limiter applies
th e brakes automaticall y.
Yo u can limit the speed as follo ws:
R Variable: for speed restrictions, e.g. in built-
up areas.
R Perm anen t:for long-term speed restrictions,
e.g. when driving in winter tyre mode.
Yo u can operate theva riable limiter with the
cruise control le ver.Yo u can store any speed
abo ve30 km/h. You can also per form settings
while theve hicle is stationary if theve hicle has
been star ted.

Information on the permanent limiter
% The permanent limiter is only
available in cer‐
ta in countries.
If yo u wish tolimit theve hicle speed permanently
to a specific value (e.g. for driving in winter tyre
mode), you can set this speed with the perma‐
nent limiter. Yo
u can permanently limit the speed toava lue
between 160 km/h and the maximum permissi‐
ble speed (/ page160).
If yo u accelerate theve hicle using the accelera tor
pedal, a message with thestored speed is shown
in the multifunction display shortly before the set
limit speed is reached.
The permanent limiter remains active even if the
va riable limiter is deactivated. The permanent
limiter does not swit chtopassive mode even dur‐
