Special service requ irements
The prescribed service inter val is based on nor‐
mal operation of theve hicle. Service workwill need
tobe per form ed more of ten if theve hicle
is operated under arduous conditions or
increased loads, forex ample:
RRe gular city driving with frequent intermedi‐
ate stops.
RIf th eve hicle is primarily used totrave l short
dis tances.
RFo r frequent operation in mountainous ter‐
ra in or on poor road sur faces.
RIf th e engine is of ten le ftidling for long peri‐
ods.
RIn particula rly dusty condition sand/o rif air -
re circulation mode is frequently used.
In these or similar operating conditions, ha ve,fo r
ex ample, the interior air filter, engine air filter,
engine oil and oil filter changed more frequent ly.
The tires must be checked more frequently if the
ve hicle is operated under arduous conditions.
Fu rther information can be obtained at a quali‐
fi ed specialist workshop.

Operation of the active hood (pedestrian pro‐
te ction)
In cer tain accident situations, therisk of injury
to pedestrians can be reduced bythe actuation
of the active hood. The rear area of the engine
hood is raised byappr oximately 85 mm.
Fo rth e drive tothewo rkshop, reset the trig‐
ge red active hood yourself. Ifth e active hood
has been triggered, pedestrian pr otection may
be limited.
A qu alified specialist workshop must re-ins tate
th e full functionality of the active hood. The active hood is not
available in all countries.

#Observethe 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 323).
RVe hicles with a TIREFIT kit: you can repair
th e tire so that it is possible tocontinue the
journ eyfor a short period of time. Todo this,
use the TIREFIT kit (
→page 324).
RVe hicles with a Mercedes-Benz emer‐
ge ncy call sy stem: intheev ent of a break‐
down, consult the Mercedes-Benz emer gency
call sy stem Cus tomer Assis tance Center.
RChange the wheel (→page 366).
MOExtended tires (tires with run-flat proper‐
ties)
& WARNING Risk of accident when driving
in li mp-home mode
When driving in emergency mode the han‐
dling characteristics are impaired, e.g. when
cornering, when accelerating stronglyand
when braking.
#Do not exceed the specified maximum
speed.
#Av oid any abrupt steering and driving
maneuvers as well as driving over
obs tacles (curbs, pot holes, off-road).
This applies, in part icular,toa loaded
ve hicle.
#Stop driving in the emer gency mode if
yo u notice:
Rbanging noise
Rvehicle vibration
Rsmoke which smells like rubber
Rcontinuous ESP®inter vention
Rcrac 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.
With MOExtended tires (run-flat tires), you can
continue todrive your vehicle even if there is a
tot al loss of pressure in one or more tires. How‐
eve r,th e tire af fected must not show any clearly
visible damage.
Yo u can recognize MOExtended tires bythe
MOExtended marking which appears onthe side
wa ll of the tire.
Ve hicles with tire pressure monitoring sys‐
te m: MOExtended tires may only be used in con‐
junction wi than activated tire pressure monitor‐
ing sy stem.
If a pressure loss warning message appears in
th e multifunction display:
RCheck the tire for dama ge.
Breakdown assis tance 323

The system checks the tire pressure and the tire
te mp erature of the tires mounted on theve hicle
by means of a tire pressure sensor.
New tire pressure sensors, e.g. in winter tires,
are automatically taught-in thefirs t time they are
driven.
The tire pressure appears in the multifunction
display (
→page 208).
If th ere is a subs tantial pressure loss or if the
tire temp erature is excessive, a warning is given:
RVia display messages (→page 414).
RViath eh warning lamp in the instrument
clus ter (→page 446).
It is the driver's responsibility toset the tire
pressure tothere commended cold tire pressure
suitable forth e operating situation. Set the tire
pressure for cold tires using a tire pressure
ga uge. Notethat the cor rect tire pressure forth e
cur rent operating situation must firs t be taught-
in to the tire pressure monitoring sy stem.
In most cases, the tire pressure monitoring sys‐
te m will auto matically update the new refere nce
va lues af teryo u ha vechanged the tire pressure. Yo
u can, ho wever,also update there fere nce val‐
ues byrestarting the tire pressure monitoring
sy stem manually (
→page 349).
Sy stem limitations
The tire pressure monitoring sy stem does not
issue a warning:
RIfth e tire pressure is set incor rectly.
RIfth ere is a sudden pressure loss caused, for
ex ample byafo re ign object penetrating the
tire.
RIf th ere is a malfunction caused byano ther
