WARNING Risk of burn s duetorepeat‐
edly switching on the seat heating
Re peatedly switching on the seat heating can
cause the seat cushion and seat backrest
padding tobecome very hot.
In particular, the health of persons with limi‐
te dte mp erature sensitivity or a limited ability
to react tohigh temp eratures may be af fec‐
te d or they may even suf fer burn-like injuries. #
Do not repeatedly switch on the seat
heating. To
protect against overheating, the seat heating
may be temp orarily deactivated af ter it is
switched on repeatedly.

#
Avoid high engine speeds and driving at
full thro ttle until the engine has reached
its operating temp erature. Note
s on short-distance trips
If th eve hicle is predominantly used in short-dis‐
ta nce driving, a fault in the automatic cleaning
function of the diesel particulate filter can occur.
Due tothis, fuel may also accumulate in the
engine oil and cause engine failure.
During automatic cleaning, extreme lyhot exhaust
ga ses escape from theex haust pipe. Maintain a
dis tance of at least 1 m to other objects, e.g.
par kedve hicles, in order toavoid material dam‐
age.
If yo u main lydrive short dis tances, you should
drive on a mo torw ay or go for a country drive for
20 minutes every500 km. This facilitates the
re ge neration of the diesel particulate filter.
Information about driving abroad
Service
An extensive Mercedes-Benz service is also avail‐
able abroad. Ne vertheless, please remember that
services or spare parts may not be available
immediatel y.The releva nt wo rkshop directories
are available from a Mercedes-Benz Service
Cent re.
Fu el
In some countries, only fuels with an inc reased
sulphur con tent are available.
Uns uitable fuel can cause engine damage. Yo u
can find fur ther information under "Fuel"
(/ page 270).
Ad Blue ®
Ad Blue ®
is not available in suf ficient quality in all
countries. Therefore, check theAd Blue ®
leve l,
particular lybefore driving outside Europe
(/ page 148). Consul t aqualified specialist
wo rkshop for advice.
Yo u can find information about AdBlue ®
in "Oper‐
ating fluids and capacities" (/ page271).
Low beam
In countries in whi chtraf fic drives on the oppo‐
site side of thero ad from the count ryin which
th eve hicle is regis tere d, you will ha vetoswitch
th e headlamps tosymmetrical dipped beam. This
will pr event oncoming traf fic from being dazzled.
Symm etrical dipped beam will no longer illumi‐
nate the edge of the car riag ewa y as far or as
high. Ve
hicles with halogen headlamps:
It is not necessa ryto change the headlamps over
to symmetrical dipped beam. The statutory
requ irements of the count ries in which tra ffic
drives on the opposite side of thero ad from the
country in whi ch theve hicle is regis tere d are also
met without changing over.
Ve hicles with LED headlamps:
Yo u can set the low beam for driving on theright
or left via the on-board computer (/ page189).
Information about transport byrail
Tr ansporting your vehicle byrail may be subject
to cer tain restrictions or requ ire special meas‐
ures tobe take n in some countries due tovarying
tunnel heights and loading standards.
Yo u can obtain information about this from a
Mercedes-Benz Service Cent re.

The drive program switches automatically

Note
s onthe 4MATIC 4MATIC ensures permanent drive
for all four
wheels, and toge ther with ESP ®
it impr oves the
ve hicle's traction.
% In wintry
road conditions, the maximum
ef fect of 4MATIC can be achie ved only if you
use winter tyres (M+S tyres), with sn ow
ch ains if necessar y.
Use DSR (Downhill Speed Regulation) when driv‐
ing downhill off-road (/ page160).
If yo ufa ilto adapt your driving style, 4MATIC can
neither reduce therisk of an accident nor over‐
ri de the la wsof ph ysics. 4MATIC cannot take
account of road, weather and traf fic conditions.
4MATIC is only an aid. You are responsible espe‐
cially for maintaining a safe dis tance from the
ve hicle in front, forve hicle speed, for braking in
good time and forst ay ing in lane. AIRMATIC
Fu
nction of AIRMATIC AIRMATIC is an air suspension sy
stem with an all-
ro und le vel control sy stem, which also ensures
th e best possible suspension and cons tant
ground clearance, even wi tha laden vehicle.
When you drive at speed, theve hicle is lo wered
automatically toimpr ovedriving saf ety and to
re duce fuel consum ption. There is also the option
of raising theve hicle le vel while driving slowl y,
e.g. for driving off public roads. The AIRMATIC
settings are dependent on the drive program
selection.
AIRMATIC consists of thefo llowing functions and
components:
R all-round air suspension
R speed-dependent lo wering toreduce fuel con‐

aptive brake lights warnfollowing traf fic in an
emergency braking situation with th efo llowing
signals:
R Byflashing the 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 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.
