Obse rveth e information and warning
no tes on MOExtended tyres (run-flat
tyres). In
theeve nt of a flat tyre, thefo llowing options
are available depending on your vehicle's equip‐
ment:
R Vehicles with MOExtended tyres: it is pos‐
sible tocontinue the journey for a short
period of time. Make sure you obse rvethe
no tes on MOExtended tyres (run-flat tyres)
(/ page 267).
R Vehicles with a TIREFIT kit: you can repair
th e tyre so that it is possible tocontinue the
jou rney for a short period of time. Todo this,
use the TIREFIT kit (/ page 268). R
Vehicles with Mercedes me connect: you
can make a call for breakdown assi stance via
th eove rhead control panel in the case of a
breakdown (/ page217).
R Allvehicles: change the wheel

WARNING Risk of accident when driving
in eme rgency mode
When driving in emer gency mode, the han‐
dling characteristics are impaired. e.g. when
cornering, when accelerating stronglyand
when braking. #
Do not exceed the permissible maxi‐
mum speed. #
Avoid any abrupt steering and driving
maneuvers as well as driving over
obs tacles (curbs, pot holes, off-road).
This applies, in pa rticular, toa loaded
ve hicle. #
Stop driving in the emer gency mode if
yo u notice:
R banging noise
R vehicle vibration
R smoke which smells like rubber
R continuous ESP ®
inter vention
R crac ksin tire side walls #
After driving in emergency mode ha ve
th erims checkedby aqu alified special‐
ist workshop with rega rd totheir fur ther
use. #
The defective tire must be replaced in
eve rycase. Wi
th MOExtended tyres (run-flat tyres), you can
continue todrive your vehicle even if there is a
tot al loss of pressure in one or more tyres. How‐
eve r,th e tyre af fected must not show any clearly
visible damage.
Yo u can recognise MOExtended tyres bythe
MOExtended marking which appears onthe side
wa ll of the tyre. Breakdown assis

vethefo llowing no tes when using snow
ch ains:
R Snow ch ains are on ly permissible for cer tain
wheel/tyre combinations. You can obtain
information about this from a Mercedes-Benz
Service Cent re.
R For saf etyre asons, on lyuse sn ow chainsthat
ha ve been specifically appr ovedfo ryo ur

with the same quality standard.
R If sn ow ch ains are fitted, the maximum per‐
missible speed is 50 km/h.
R Vehicles with le vel control: if snowchains
are fitted, only drive at raised vehicle le vel.
% You can permanently limit the maximum
ve hicle speed for driving with winter tyres
(/ page 146).

WARNING Risk of accident due toinsuf‐
fi cient or excessive tyre pressure
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
une venly, which may greatlyimpair tyre
traction.
R The driving characteristics, as well as
st eering and braking, may be greatly
impaired. #
Comply with there commended tyre
pressure and check the tyre pressure of
all tyres including the spare wheel regu‐
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-
ro ad driving #
Adjust the tyre pressure as necessar y. Ty
re pressure which is too high or too low can:
R Shor tenth e service life of the tyres.
R Cause increased tyre damage.
R Adversely af fect driving characteristics and
th us driving saf ety, e.g. due toaquaplaning. &
WARNING Risk of accident from repea‐
te d tyre pressure drop
If th e tyre pressure drops repeatedly, 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
objects. #
Check whe ther the wheel or valve has a
leak. 286

WARNING Risk of accident caused by
incor rect wheel and tyre dimensions
The wheel or tyre size and the tyre type of
th e emer gency spa rewheel or spare wheel
and the wheel tobe replaced may dif fer.
Mounting an emer gency spa rewheel/spare
wheel may se verely impair the driving char‐
acteristics.
To preve nt hazardous situations: #
Adapt your driving style according lyand
drive carefull y. #
Neverfit more than one emer gency
spa rewheel or spare wheel that dif fers
in size. #
Only use an emer gency spa rewheel or
spare wheel of a dif fere nt size brie fly. #
Do not switch off ESP ®
. #
Have the emer gency spa rewheel or
spare wheel of a dif fere nt size replaced
at the nearest qualified specialist work‐ shop. The new wheel must ha
vethe
cor rect dimensions. The collapsible spa
rewheel is only available in
cer tain countries.
The collapsible spare wheel is an emer gency
wheel which is only suitable for use for a limi ted
period of time and in a restricted manner in the
eve nt of a flat tyre (e.g. until the nearest work‐
shop).
The tyre side walls are folded when in transpo rt
mode. Before use, the collapsible spare wheel
has tobe inflated with the accompanying com‐
pressor.
Check the tyre pressure of the collapsible spare
wheel once fitted. Co rrect the pressure as nec‐
essar y.
The maximum permissible speed with a collapsi‐
ble spare wheel fitted is 80 km/h.
Do not fit snow chains with the collapsible spare
wheel.
Re place the collapsible spare wheel af ter six
ye ars at the latest, rega rdless of wear. %
Ve
hicles with a tyre pressure monitoring
sy stem: if a collapsible spare wheel is fitted
th e tyre pressure monitoring sy stem cann ot
function reliably. Only restart the sy stem
again when the collapsible spare wheel has
been replaced with a new wheel.
Ve hicles with a tyre pressure monitoring
sy stem: for a few minutes af ter a collapsible
spare wheel is fitted, the sy stem may still
