In th e eve nt of a fl at tire, th e fo llowing options
are av ailable depending on yo ur ve hicle's equip‐
ment: R
Ve hicles with MOExtended tires: it is pos‐
sible to continue th e journey fo r a short
period of time. Make sure yo u obse rv e th e
no te s on MOExtended tires (run-flat tires)
( →
page 394).R
Ve hicles with a TIREFIT kit: yo u can re pair
th e tire so th at it is possible to continue th e
jou rn ey fo r a short period of time. To do th is,
use th e TIREFIT kit ( →

WA RNING Risk of accident when driving
in li mp -home mode
When driving in emergency mode th e han‐
dling ch aracteristics are impaired, e.g. when
cornering, when accelerating stro ng ly and
when braking.

R
If driving on, obser ve th e fo llowing no te s.
Driving distance possible in limp-home mode
af te r the pressure loss wa rn ing:
Load condition Driving distance pos‐
sible in limp-home
mode
Pa rt ially laden 50 miles (80 km)
Fu lly laden 19 miles (30 km)R
The driving dis ta nce possible in li mp -home
mode may va ry depending on th e driving
st yl e.R
Maximum permissible speed 50 mp h
(80 km/h).
If a tire has gone fl at and cannot be re placed
with an MOEx te nded tire, yo u can use a st and‐
ard tire as a te mp orary measure.
TIREFIT kit st orage location
The TIREFIT kit is located under th e trunk fl oor. Mercedes‑AMG ve hicles: obse rv e th e no te s in
th e Supplement. Otherwise, yo u may not re cog‐
nize dangers.
Plug-in hy brid: obser ve th e no te s in th e Supple‐
ment. Otherwise, yo u may not re cognize dan‐
ge rs .

WA RNING Risk of accident when using
tire sealant.
In th e fo llowing situations, th e tire sealant is
unable to pr ov ide suf fi cient breakdown assis‐
ta nce, as it is unable to seal th e tire proper ly :R
There are cuts or punctures in th e tire

Yo u ha ve driven at a ve ry low tire pres‐
sure or on a fl at tire.

DA NG ER Risk of accident due to incor‐
re ct tire pressure
Every tire, including th e spare (if pr ov ided),
should be ch ec ke d when cold at least once a
month and inflated to th e pressure re com‐
mended by th e ve hicle manufacturer (see
Ti re and Loading In fo rm ation placard on th e
B-pillar on th e driver ’s side or th e tire pres‐
sure label on th e inside of th e fuel fi ller fl ap
of yo ur ve hicle). If yo ur ve hicle has tires of a
dif fe re nt size th an th e size indicated on th e
Ti re and Loading In fo rm ation placard or th e tire pressu re ta ble, yo u need to de te rm ine
th e proper tire pressure fo r th ose tires.
As an added saf et y fe ature, yo ur ve hicle has
been equipped with a tire pressure monitor‐
ing sy st em (TPMS) th at illuminates a low tire
pressure indicator lamp when one or more of
yo ur tires are sign if icantly underinflated.
Ac cording ly , if th e low tire pressure indicator
lamp lights up, yo u should st op and ch eck
yo ur tires as soon as possible, and inflate
th em to th e proper pressure. Driving on a
significant ly underinflated tire causes th e tire
to ove rh eat and can lead to tire fa ilure.
Und erinflation also increases fuel consump‐
tion and re duces tire tread life, and may
af fe ct th e ve hicle's handling and braking abil‐
ity. Please no te th at th e TPMS is not a substi‐
tute fo r proper tire maintenance, and it is th e
driver's re sponsibility to maintain cor re ct tire
pressure, ev en if underinflation has not
re ached th e le ve l to trig ge r illumination of
th e TPMS low tire pressure indicator lamp.
Yo ur ve hicle has also been equipped with a
TPMS malfunction indicator to indicate when th e sy st em is not operating properly. The
TPMS malfunction indicator is combined with
th e low tire pressure indicator lamp. When
th e sy st em de te cts a malfunction, th e indica‐
to r lamp will fl ash fo r app ro xima te ly a minute
and th en re main continuously illumina te d.
This sequence will continue upon subsequent
ve hicle st art-ups as long as th e malfunction
ex ists.
When th e malfunction indicator is illumina‐
te d, th e sy st em may not be able to de te ct or
signal low tire pressure as intended. TPMS
malfunctions may occur fo r a va ri et y of re a‐
sons, including th e ins ta llation of incompati‐
ble re placement or alternate tires or wheels
on th e ve hicle th at pr ev ent th e TPMS from
functioning proper ly .
Alw ay s ch eck th e TPMS malfunction wa rn ing
lamp af te r re placing one or more tires or
wheels on yo ur ve hicle to ensure th at th e
re placement or alternate tires and wheels
allow th e TPMS to continue to function prop‐
er ly .41 8
Wheels and tires

Obser ve th e fo llowing when selecting, mounting
and re placing tires:R
Only use tires and wheels of th e same type
(summer tires, winter tires, MOEx te nded
tires) and th e same make.R
Only mount wheels of th e same size on one
axle (left and ri ght).
It is only permissible to ins ta ll a dif fe re nt
wheel size in th e eve nt of a fl at tire in order
to drive to th e specialist wo rk shop.R
Only mount tires of th e cor re ct size onto th e
wheels. R
Ve hicles with a tire pressure monitoring
sy st em: All moun te d wheels must be equip‐
ped with functioning sensors fo r th e tire
pressure monitoring sy st em.R
At te mp eratures below 45 °F (7 °C), use win‐
te r tires or all-season tire mar ke d M+S fo r all
wheels.
Wi nter tires bearing th e M snowflake sym‐
bol in addition to th e M+S marking pr ov ide
th e best possible grip in wintry ro ad condi‐
tions. R
Fo r M+S tires, only use tires with th e same
tread. R
Obser ve th e maximum permissible speed fo r
th e M+S tire mounted.
If th is is below th e ve hicle's maximum speed,
th is must be indicated in an appropriate label
in th e driver's fi eld of vision. R
Break in new tires at moderate speeds fo r
th e fi rs t 60 miles (100 km). R
Re place th e tires af te r six ye ars at th e latest,
re ga rd less of we ar. R
When re placing with tires that do no t fe a‐
ture ru n-flat ch aracteristics: ve hicles with
MOExtended tires are not equipped with a
TIREFIT kit at th e fa ctor y. Equip th e ve hicle
with a TIREFIT kit af te r re placing with tires
th at do not fe ature ru n-flat ch aracteristics,
e.g. winter tires.

ta ct a qu alified specialist wo rk shop.
