MOBILITY
General information
▷ To enable continued driving, liquid sealant is
pumped into the tire, which hardens and
seals the damage from the inside.
▷ Follow the instructions on using the tire repair
set found on the compressor and sealant
bottle.
▷ Use of the tire repair set may be ineffective if
the tire puncture measures approx. 4 mm or
more.
▷ Contact a dealer's service center or another
qualified service center or repair shop if the
tire cannot be made drivable.
▷ Do not remove foreign bodies that have pe‐
netrated the tire. Remove foreign objects only
when they are visibly protruding from the tire.
▷ Pull the speed limit sticker off the sealant bot‐
tle and apply it to the steering wheel.
▷ The use of a sealing compound can damage
the wheel electronics. In this case, have the
electronics checked and replaced at the next
opportunity.
▷ The compressor can be used to check the
tire inflation pressure.
