If apressur eloss warning message appears
in the multifu nctiondisplay:
R observe theinstruct ionsinthe display mes-

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.
