Therefore, you must not tamper with elec-
tronic components or their software.
The seat belts, together with SRS (Supple-
mental Restraint System), are complemen-
tary, co-ordinated restraint systems
(Y page 41). They reduce the risk of injury
in specific, pre-defined types of accident sit-
uations and thereby increase occupant
safety. However, seat belts and airbags gen-
erally do not protect against object spene-
tratin gthe vehicle from the outside. 40
