nction of the 4MATIC
4MATIC ensures that all four wheels are driven
when needed. Toge ther with ESP ®
and 4ETS,
4MATIC impr ovesth e traction of your vehicle
whene ver a driven wheel spins due toinsuf fi‐
cient traction.
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.
% In wint ryroad conditions, the maximum
ef fect of 4MATIC can be achie ved only if you
use winter tyres (M+S tyres), with sn ow

Pe rm anent limi ter
If th eve hicle should ne verexc eed a specific
speed (e.g. for driving in winter tyre mode), you
can set this speed with the permanent 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 (/ page190).
Shortly before the set speed is reached, it
appears in the multifunction displa y.When you
confirm the message with %, display mes‐
sages no longer appear until you swit choff the

once theve hicle has been restar ted or if the set

Note
s on noise or unusual handling charac‐
te rist ics
While driving, pay attention tovibrations, noises
and unusual handling characteristics, e.g. pulling
to one side. This may indicate that the wheels or
tyres are damaged. If you suspect that a tyre is
defective, reduce your speed immediatel y.Stop
th eve hicle as soon as possible tocheck the
wheels and tyres for dama ge. Hidden tyre dam‐
age could also be causing the unusual handling

ha ve the tyres and wheels checked at a qualified
specialist workshop. Note

WARNING Risk of accident from dam‐
aged tyres
Dama ged tyres can cause tyre pressure loss.
As a result, you could lose cont rol of your
ve hicle. #
Check the tyres regularly for signs of
dama geand replace any damaged tyres
immediatel y. Car
ryout thefo llowing checks on all wheels reg‐
ularly, at least once a month or as requ ired, e.g.
prior toa long journey or driving off- road:
R Check the tyre pressure (/ page 409).
R Visually inspect tyres and wheels for dam‐
age.
R Check theva lve caps.
The valves must be pr otected against mois‐
ture and dirt bytheva lve caps appr oved
especially foryo ur vehicle byMercedes-Benz.

Underinfla ted or overinfla ted tyres pose the
fo llowing risks:
R The tyres may bur st, especially as the
load and vehicle speed increase. R
The tyres may wearexc essively and/or

R The driving characteristics, as well as
st eering and braking, may be greatly

larly:
R at least once a month
R when the load changes
R before embarking on a lon ger journey
R if operating conditions change, e.g. off-

WARNING Risk of accident from repea‐

If th e tyre pressure drops repeatedl y,the
wheel, valve or tyre may be damaged.
Insuf ficient tyre pressure can cause the tyres
to bur st. #
Inspect the tyre for signs of fore ign

Check whe ther the wheel or valve has a
leak. #
Ifyo u are unable torectify the damage,

on the tyre pressure table on the inside of the

cold. Conditions for cold tyres:
R The vehicle has been par ked with the tyres
out of direct sunlight for at least thre e hours.
R The vehicle has tr avelled less than 1.6 km.
A rise in the tyre temp erature of 10°C increases
th e tyre pressure byappr ox.10 kPa (0.1 bar/

per form ance tyres
The special tyre tread in combination with
th e optimised tyre compound, means that
th erisk of skidding or hydroplaning on wet
ro ads is inc reased.
In addition, the tyre grip is greatly reduced at
a low outside temp erature and tyre running
te mp erature. #
Switch on the ESP ®
and adapt your
driving style accordingly. #
Use M+S tyres at outside temp eratures
of less than 50 °F. Obse
rveth efo llowing when selecting, fitting and
re placing tyres:
R Countr y-specific requirements for tyre
appro valth at define a specific tyre type for
yo ur vehicle.
Fu rthermore, the use of cer tain tyre types in
cer tain regions and areas of operation can
be highly beneficial.
R Only use tyres and wheels of the same type
(summer tyres, winter tyres, MOEx tended
tyres) and the same make.
R Only fit wheels of the same size on one axle
(left and right).
It is only permissible tofit a di fferent wheel
size in theeve nt of a flat tyre in order to
drive tothe specialist workshop.
R Only fit tyres of the cor rect size onto the
wheels.
R Do not make any modifications tothe brake
sy stem, the wheels or the tyres.
The use of shims or brake dust shields is not
permitted and may in validate theve hicle's
