5-1. Essential information
Event data recorder
In a crash or a near car crash event
The SRS airbag sensor assembly contains the EDR. In a crash or a
near car crash event, this device may record some or all of the follow-
ing information:
●Engine speed
●Whether the brake pedal was applied or not
●Vehicle speed
●To what extent the accelerator pedal was depressed
●Position of the transmission shift lever
●Whether the driver and front passenger wore seat belts or not
●Driver's seat position
●SRS airbag deployment data
●SRS airbag system diagnostic data
●Front passenger's occupant classification
The information above is intended to be used for the purpose of
improving vehicle safety performance. Unlike general data recorders,
the EDR does not record sound data such as conversation between
passengers.
Your vehicle has computers that monitor and control certain aspects
of your vehicle. These computers assist in driving and maintaining
optimal vehicle performance.
Besides storing data useful for troubleshooting, there is an event
data recorder (EDR) that records data in a crash or a near car
crash event.

■Front passenger detection sensor and passenger seat belt reminder
●If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash, even if a passen-
ger is not sitting in the seat.
●If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
■Changing the engine oil (U.S.A. only)
Make sure to reset the oil change system. (P. 298)
■
When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level.
Pushing the tire pressure warning reset switch does not turn off the tire
pressure warning light.
■The tire pressure warning light may turn on due to natural causes
The tire pressure warning light may turn on due to natural causes such
as natural air leaks or tire inflation pressure changes caused by temper-
ature. In this case, adjusting the tire inflation pressure will turn off the
warning light (after a few minutes).
