If a tire inflation pressure of 26 psi (1.8 bar)
is not attained, tire is too severely damaged
for TIREFIT to provide a reliable tire repair.
In this case, TIREFIT cannot properly seal
the tire.

The Tele Aid system consists of three
types of response: automatic and man-
ual emergency, roadside assistance
and information. Tele Aid is initially ac-
tivated by completing a subscriber
agreement and placing an acquain-
tance call.
The Tele Aid system is operational pro-
vided that the vehicle’s battery is
charged, properly connected, not dam-
aged and cellular and GPS coverage is
available.
Telematics*
A combination of the terms “telecom-
munications” and “informatics”.
