General notes With
MOExt ended tires(tires withrunflatchar-
acteristics ),you can cont inue todrive yourvehi-
cle even ifthere isatotal lossofpressure inone
or more tires.Theaffected tiremust notshow
any clearly visibledamage.
You canrecogniz eaMOExt ended tirebythe
MOExt ended marking whichappears onthe
sidewa llof the tire. Youwillfind thismarking
next tothe tire size designation, theload-bear-
ing capacity andthespeed index(Ypage 305).
MOExt ended tiresmaybeused onlyinconj unc-
tion with anactivated tirepressure losswarning
system (Canada only)ortire pressure monitor
(USA only).
If apressur eloss warning message appears
in the multifu nctiondisplay:
R observe theinstruct ionsinthe display mes-
sages (Ypage 213).
R check thetire fordamage
R ifdriving on,observe thefollowing notes
The driving distance possibleinrun-flat modeis
approximately 50miles (80km) when thevehi-
cle ispartially laden.Whenthevehicle isfully
laden itis approximately 19miles (30km).
In addition tothe vehicle load,thedriving dis-
tance possible depends upon:
R vehicle speed
R road condition
R outside temperature
The driving distance possibleinrun-flat mode
may bereduced byextrem edriving condition s
or maneuvers, oritcan beincreased througha
moderate styleofdriving. The
driving distance possibleinrun-flat modeis
counted fromthemoment thetire pressure loss
warning appears inthe multifunction display.
You must notexceed amaximum speedof
50 mph (80km/h).
When replacing oneorall tires, please observe
the following specifications foryour vehicle's
tires:
R size
R type and
R the "MOExt ended" marking
If atire has gone flatand cannot bereplaced
with aMOExt ended tire,astandard tiremay be
used asatemporary measure.Makesurethat
you usetheproper sizeandtype (summer or
winter tire).
Vehicles equippedwith MOExt ended tiresare
not equipp edwith aTIREFIT kitatthe factory. It
is therefore recommen dedthat youadditionally
equip yourvehicle withaTIREFIT kitifyou mount
tires thatdonot feature run-flat properties, e.g.
winter tires.ATIREFIT kitmay beobtained from
a qual ified specialist workshop.
