#Observ eth e information and warning
no tes on MOExtended tires (run-flat
tires).
In theeve nt of a flat tire, thefo llowing options
are available depending on your vehicle's equip‐
ment:
RVe hicles with MOExtended tires: it is pos‐
sible tocontinue the journey for a short
period of time. Make sure you observ eth e
no tes on MOExtended tires (run-flat tires)
(
→page 319).
RVe hicles with a TIREFIT kit: you can repair
th e tire so that it is possible tocontinue the
journ ey for a short period of time. Todo this,
use the TIREFIT kit (
→page 320).
RVe hicles with a Mercedes-Benz emer‐
ge ncy call sy stem: intheeve nt of a break‐ down, consult
the Mercedes-Benz emer gency
call sy stem Cus tomer Assis tance Center.
RChange the wheel (→page 362).
MOExtended tires (run-flat tires)
Wi th MOExtended tires (run-flat tires), you can
continue todrive your vehicle even if there is a
to ta l loss of pressure in one or more tires. How‐
eve r,th e tire af fected must not show any clear ly
visible dama ge.
Yo u can recognize MOExtended tires bythe
MOExtended marking which appears on the side
wa ll of the tire.
Ve hicles with a tire pressure monitoring sys‐
te m: MOExtended tires may only be used in con‐
junction wi than activated tire pressure monitor‐
ing sy stem.

WARNING Risk of accident when driving
in li mp-home mode
When driving in li mp-home mode, the han‐
dling characteristics are impaired. e.g. when
cornering, when accelerating stronglyand
when braking.
#Do not exceed the maximum permissi‐
ble speed.
#Av oid any abrupt steering and driving
maneuvers as well as driving over
obs tacles (curbs, pot holes, cross-coun‐
try). This applies, in part icular,toa loa‐
ded vehicle.
#Stop driving in limp-home mode if you
notice:
Rbanging noise
Rve hicle vibration
Rsmoke which smells like rubber
Rcontinuous ESP®inter vention

WARNING Risk of an accident due to
insuf ficient tire pressure
Ti re s with pressure that is too low can over‐
heat and bur stas a result.
In addition, they also suf fer from excessive
and/or ir regular wear, which can significantly
impair the braking properties and the han‐
dling characteristics.
#Av oid excessively low tire pressures in
all the tires, including the spare wheel.
Tire pressure which is too low can cause:
RTire defects as a result of overheating.

RIrre gular wear
RIncreased fuel consum ption

WARNING Risk of accident from exces‐
sive tire pressure
Ti re s with excessively high pressure can

by highw ayfill, pot holes etc.
In addition, they also suf fer from ir regular

DANG ER Risk of accident due toincor‐
re ct tire pressure
Every tire, including the spare (if pr ovided),
should be checked when cold at least once a
month and inflated tothe pressure recom‐
mended bytheve hicle manufacturer (see
Ti re and Loading Info rmation placard on the
B-pillar on the driver ’sside or the tire pres‐
sure label on the inside of the fuel filler flap
of your vehicle). If your vehicle has tires of a
dif fere nt size than the size indicated on the
Ti re and Loading Info rmation placard or the
tire pressure table, you need todeterm ine
th e proper tire pressure forth ose tires.
As an added saf etyfe ature, your vehicle has
been equipped with a tire pressure monitor‐
ing sy stem (TPMS) that illuminates a low tire
pressure indicator lamp when one or more of
yo ur tires are signif icantly underinflated.
Ac cording ly, if the low tire pressure indicator
lamp lights up, you should stop and check
yo ur tires as soon as possible, and inflate
th em tothe proper pressure. Driving on a
significantly underinflated tire causes the tire
to ove rheat and can lead totire failure.
Un derinflation also increases fuel consump‐
tion and reduces tire tread life, and may
af fect theve hicle's handling and braking abil‐
ity. Please no tethat the TPMS is not a substi‐
tute for proper tire maintenance, and it is the
driver's responsibility tomaintain cor rect tire
pressure, even if underinflation has not
re ached the le velto trig ger illumination of
th e TPMS low tire pressure indicator lamp.
Yo ur vehicle has also been equipped with a
TPMS malfunction indicator toindicate whenthe sy stem is not operating proper ly. The
TPMS malfunction indica tor is combined with
th e low tire pressure indicator lamp. When
th e sy stem de tects a malfunction, the indica‐
to r lamp will flash for app roxima tely a minute
and then remain continuously illumina ted.
This sequence will continue upon subsequent
ve hicle start-ups as long as the malfunction
ex ists.
When the malfunction indicator is illumina‐
te d, the sy stem may not be able todetect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variet yof rea‐
sons, including the ins tallation of incompati‐
ble replacement or alternate tires or wheels
on theve hicle that pr eventthe TPMS from
functioning properly.
Alw aysch eck the TPMS malfunction warning
lamp af terre placing one or more tires or
wheels on your vehicle toensure that the
re placement or alternate tires and wheels
allow the TPMS tocontinue tofunction prop‐
erly.

DANG ER Risk of accident due toinade‐

The traction grade assigned tothis tire is
based on stra ight-ahead braking traction
te sts, and does not include either accelera‐

The traction grades – from highest tolowest –
are AA, A,B and C. Those grades represent the
tire's ability tostop on wet pa vement as meas‐
ured under controlled conditions on specified
go vernment test sur faces made of asphalt and
concr ete.
Te mp erature grade
&
WARNING Risk of accident from tire
ove rheating and tire failure
The temp erature grade forth is tire is es tab‐
lished for a tire that is proper ly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately
or in combination, can cause excessive heat
build-up and possible tire failure.
#Obser vethere commended tire pres‐
sure s and regularly check the tire pres‐
sure of all tires including the spare
wheel.
#Ad just the tire pressure as necessar y.
Thetemp erature grades are A (the highest), B
and C. They represent the tire's resis tance tothe
ge neration of heat and its ability todissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel. Sus‐
ta ined high temp eratures can cause the material
of the tire todegenerate and reduce tire life. Fur‐
th ermore, excessive temp eratures can lead to
sudden tire failure. Grade C cor responds toa

tires must meet under therequ irements of the
US Department of Transpor tation.
DO T,Tire Identification Number (TIN)
US tire regulations stipulate that eve rytire man‐
ufactu rer or retreader must imprint a TIN in or
on the side wall of each tire produced.

Uniform Tire Quality Grading Standards: a
uniform standard tograde thequ ality of tires
with rega rd totread quality, tire traction and
te mp erature characteristics. The quality grading
assessment is made bythe manufacturer follow‐
ing specifications from theU. S. go vernment. The
qu ality grade of a tire is imprinted on the side

Re commended tire pressure :th ere commen‐
ded tire pressure is the tire pressure specified
fo rth e tires mounted totheve hicle at thefa c‐
to ry.

mum permissible load and the maximum permis‐
sible vehicle speed.
The tire pressure table conta insthere commen‐
ded tire pressure for cold tires under various
operating conditions, i.e. loading and/or speed
of theve hicle.
Increased vehicle weight due tooptional
equipment: the combined weight of all standard
and optional equipment available forth eve hicle, re
ga rdless of whe ther it is actually ins talled on
th eve hicle or not.
Rim: the part of the wheel on which the tire is
mounted.
GA WR (Gross Axle Weight Rating): the GAWR
is the maximum gross axle load. The actual load
on an axle must ne verexc eed the gross axle
we ight rating. The gross axl e
we ight rati
ng can
be found on theve hicle identification plate on
th e B‑pillar on the driver's side.
Speed rating: the speed rating is pa rtof the tire
identification. It specifies the speed range for
which a tire is appr oved.
GV W (Gross Vehicle Weight): the gross vehicle
we ight comprises thewe ight of theve hicle

GV WR (Gross Vehicle Weight Rating): the
GV WR is the maximum permitted gross weight of
the fully laden vehicle (weight of theve hicle
