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.
Observethe maximum permissible speedfor atire sealed with tire sealant 50mph (80 km/h).#Affixthe upper section ofthe TIREFITstickertothe instrument cluster in a location whereit will be easilyseenbythe driver.
