In this section you will learn the most
important facts about the restraint
systems of the vehicle.
The restraint systems are
ț Seat belts ( ୴ page 79)
ț Child restraints ( ୴ page 95)
ț Lower Anchors and Tethers for
CHildren (LATCH) (
୴ page 93)
Additional protection provide
ț Supplemental Restraint System (SRS)
with
ț Air bags ( ୴ page 74)
ț Air bag control unit (with crash
sensors)
ț Emergency Tensioning Device
(ETD) for seat belts (
୴ page 82)
ț Active head restraints ( ୴ page 83)
Air bag system components with
ț Front passenger front air bag off
indicator lamp (
୴ page 92)
ț Front passenger seat with Occupant
Classification System (OCS)
(
୴ page 88)
Although independent systems, their
protective functions work in conjunction
with each other.
The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates early detection of malfunctions.
The
1 indicator lamp in the instrument
cluster ( ୴ page 26) comes on when the
ignition is switched on and goes out no
later than a few seconds after the engine
was started.
The SRS components are in operational
readiness if the
1 indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the
1 indicator lamp:
ț fails to go out no later than approxi-
mately 4 seconds after the engine was
started
ț does not come on at all
ț comes on after the engine was started
or while driving
