You can use TIREFIT tire sealanttoseal perfora‐tion damageof upto0.16in (4 mm), particularlythose inthe tire contact surface.You can useTIREFIT in outsidetemperatures downto-4 °F(-20 °C).
&WARNINGRisk of accident when usingtire sealant.
Inthefollowing situations,the tire sealant isunabletoprovide sufficient breakdown assis‐tance, as it is unabletosealthe tire properly:
RThere are cuts or punctures inthe tirelargerthanthose previously mentioned.
RThe wheelrim is damaged.
RYou havedriven at averylow tire pres‐sure or on aflat tire.
#Do not continue driving.
#Consult aqualified specialistworkshop.

&WARNINGRisk of injuryand poisoningfrom tire sealant
The tire sealant is harmful and causes irrita‐tion. Do not allow ittocome into contactwith the skin,eyes or clothing, and do notswallow it. Do not inhale tire sealant fumes.Keepthe tire sealantawayfromchildren.
Ifyou come into contact withthe tire sealant,observethefollowing:
#Rinse offthe tire sealant fromyour skinimmediately usingwater.
#If tire sealantgets intoyoureyes,thor‐oughlyrinse outtheeyes using cleanwater.
#If tire sealant has been swallowed,immediatelyrinse outthe mouththor‐oughly and drink plenty ofwater.Do notinducevomiting and seek medicalattention immediately.
#Change out of any clothes contamina‐ted with tire sealant immediately.
#If allergicreactions occur, seek medicalattention immediately.
*NOTEOverheating duetothe tire infla‐tion compressorrunningtoo long
#Do notrunthe tire inflation compressorfor longerthan eight minutes withoutinterruption.
Comply withthe manufacturer's safety notes onthesticker onthe tire inflation compressor.

#Pushthe plug of hose5intoflange6oftire sealant bottle1untilthe plug engages.
#Place tire sealant bottle1head downwardsintorecess2ofthe tire inflation compres‐sor.
#Removethe cap fromvalve7onthefaultytire.
#Screwfilling hose8ontovalve7.
#Insert connector4into a12V socket inyourvehicle.
#Switch onthe ignition.
#Press on and off switch3onthe tire infla‐tion compressor.The tire inflation compressor is switched on.The tire is inflated. First, tire sealant is pum‐ped intothe tire. The pressure may brieflyrisetoapproximately 500 kPa (5 bar/73 psi).
Do not switch offthe tire inflation compres‐sor duringthis phase.
#Letthe tire inflation compressorrunfor amaximum of eight minutes.The tire shouldthen haveattained a tirepressure of at least180 kPa (1.8 bar/26 psi).
If tire sealant leaksout, make sureyou cleantheaffected area asquickly as possible. It is prefera‐bletouse clearwater.
Ifyouget tire sealant onyour clothing, haveitcleaned as soon as possible with perchloroethy‐lene.
If a tirepressure of180 kPa (1.8 bar/26 psi)has not been attained after eight minutes:
#Switch offthe tire inflation compressor.
#Unscrewthefilling hose fromthevalve ofthefaulty tire.
Please notethat tire sealant may leak out whenunscrewingthefilling hose.
#Driveforwards orreverseveryslowlyforapproximately 33ft(10 m).
#Pump upthe tire again.After a maximum of eight minutesthe tirepressure must be at least180 kPa (1.8 bar/26 psi).
&WARNINGRisk of accident duetothespecified tire pressure not beingreached
Ifthe specified tire pressure is notreachedafterthe specified time,the tire istoo badlydamaged. The tire sealant cannotrepairthetire inthis instance.
Damaged tires and a tire pressurethat istoolow can significantly impair braking and han‐dlingcharacteristics.
#Do not continue driving.
#Consult aqualified specialistworkshop.

If a tire pressureof180 kPa (1.8 bar/26 psi)has been attained after eight minutes:
&WARNINGRisk of accident from drivingwithsealed tires
A tiretemporarily sealed with tire sealantimpairs drivingcharacteristics and is notsuitablefor higher speeds.
#Adaptyour drivingstyle accordinglyanddrive carefully.
#Do notexceedthe maximum speedlimit with a tirethat has beenrepairedusing tire sealant.

After use,excess tire sealant may leak outfromthefilling hose.
#Therefore, placethefilling hose intheplastic bagthat containedthe TIREFITkit.

Tiresealant contains pollutants.
#Havethe tire sealant bottle disposed ofprofessionally,e.g. at an authorizedMercedes-Benz Center.
#Switch offthe tire inflation compressor.
#Unscrewthefilling hose fromthevalve ofthefaulty tire.
#Stow the tire sealant bottle,the tire inflationcompressor andthewarning triangle.
#Pullawayimmediately.
#Stop driving after approximatelyten minutesandcheckthe tire pressure usingthe tireinflation compressor.The tire pressure must now be at least130 kPa (1.3 bar/19 psi).
&WARNINGRisk of accident duetothespecified tire pressure not beingreached
Ifthe specified tire pressure is notreachedafter a brief drive,the tire istoo badly dam‐aged. The tire sealant cannotrepairthe tireinthis instance.
Damaged tires and tire pressurethat istoolow can significantly impairthe braking prop‐erties andthe handlingcharacteristics.

A discharged battery may freeze attempera‐tures slightly aboveor below freezing point.
Duringstarting assistance or batterycharg‐ing, batterygas may bereleased.
#Alwaysthawa frozen batteryoutfirstbeforecharging it or performingstart‐ing assistance.
Ifthe indicator/warning lamps inthe instrumentcluster do not light up at lowtemperatures, it isverylikelythatthe discharged battery has fro‐zen. Inthis caseyou may neither jump-startthevehicle norchargethe battery.
