Airbag system components
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly.
The airbag sensor assembly consists of a safing sensor and an air-
bag sensor.
In certain types of severe frontal or side impacts, the SRS airbag
system triggers the airbag inflators. A chemical reaction in the
inflators quickly fills the airbags with non-toxic gas to help restrain
the motion of the occupants. Knee airbags

Daytime running light system (if equipped)
Vehicles with halogen headlights
To make your vehicle more visible to other drivers, the head-
lights turn on automatically (at a reduced intensity) whenever
the engine is started. Daytime running lights are not designed for
use at night.
Vehicles with discharge headlights
To make your vehicle more visible to other drivers, the front
position lights turn on automatically (at a increased intensity)
whenever the engine is started. Daytime running lights are not
designed for use at night.
Deactivating daytime running light (vehicles with discharge
headlights)
How to switch: P. 365
“DRL OFF” turns on when the daytime running light is deactivated.
Headlight control sensor
The sensor may not function properly if
an object is placed on the sensor, or any-
thing that blocks the sensor is affixed to
the windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction
