tires(tires withrun-flat
propert ies)
MOExt ended tires(tires withrun-flat
properties) allowyou tocont inue driving your
vehicle evenifone ormore tiresareentirely
deflated.
MOExt ended tiresmayonlybeused in
conj unction withtheactivated tirepressure
loss warning systemorwith theactivated tire
pressure monitoring system.
The maximum permissible distancewhich
can bedriven inrun-flat modedepends onthe
load inthe vehicle. Youcandrive 50miles
(80 km) ifthe vehicle ispartiall yladen and
18 miles (30km) ifit is fully laden.
The maximum permissible distancewhich
can bedriven inrun-flat modeiscounted from
the moment thetire pressure losswarning
appea rsinthe multifunction display.
You must notexceed amaximum speedof
50 mph (80km/h). G
WARNING The
handling characteristics ofyour vehicle
deteriorate inrun-flat mode,forexample:
R when cornering
R when braking
R when accelerating rapidly
Adapt yourdriving styleaccordingly andavoid
sudden changes indirection andsudden
acceleration, aswell asdriving overobstacles
(i.e. curbs, potholes), anddriving off-road.
This isparticularly thecase when thevehicle
is heavily laden.
The maximum permissible distancethatcan
be driven inrun-flat modedepends toalarge
extent onthe loads placed onthe vehicle. It can
beshorter duetohigh speeds, aheavy
load, sudden changes indirection, theroad
surface condition, outsidetemperature, etc.,
or further ifyou drive carefully and
conservatively.
Do not cont inue todrive inrun-flat modeif:
R you hear banging noises.
R the vehicle startstoshake.
R you seesmoke andsmell rubber.
R ESP ®

R there aretears inthe sidewa llsofthe tire.
Aft erdriving inrun-flat mode,youmust have

Check thetire pressure atleast once amonth.
Only check andcorrect tirepressures when
the tires arecold (Ypage 353).
Checki ngtire pressures manually To
determine andsetthe correct tire
pressure, proceedasfollows:
X Remove thevalve capofthe tire that isto
be checked.
X Press thetire pressure gaugesecurely onto
the valve.
X Read thetire pressure andcompare itwith
the recommended valueonthe Tire and
Loading Information placardonthe
B-pillar onthe driver's sideofyour vehicle.
X Ifnecessary, increasethetire pressure to
the recommended value(Ypage 353).
X Ifthe tire pressure istoo high, release air
by pressing downthemetal pininthe valve
using thetipofapen, forexample. Then check
thetire pressure againusing thetire
pressure gauge.
X Screw thevalve caponto thevalve.
X Repea tthese steps forthe other tires. Tire

Stop thevehicle assoon aspossible and
inflate thetires tothe pressure specified on
the vehicle's TireandLoading Information
placard or(where available)inthe tire

Driving onasignificantly underinflated tire
causes thetire tooverheat andcanlead to
tire failure. Underinflation alsoreduces fuel

the vehicle's handlingandstopping ability.
Check alltires when cold,including thespare
