5-1. Essential information
Event data recorder
In a crash or a near car crash eventThe SRS airbag sensor assembly c ontains 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 depressed 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 assi st in driving and maintaining
optimal vehicle performance.
Besides storing data useful for tr oubleshooting, there is an event
data recorder (EDR) that records data in a crash or a near car
crash event.

5-2. Steps to take in an emergency
*1: Open door warning buzzer:
The open door warning buzzer sounds to alert one or more of the doors is
not fully closed (with the vehicle having reached a speed of 3 mph [5 km/h]).
*2: Driver's and front passenger’s seat belt reminders:
The driver’s and front passenger’s seat belt reminders sound to alert the
driver and front passenger that his or her seat belt is not fastened. These
buzzers sound for 10 seconds after the vehicle has reached a speed of at
least 12 mph (20 km/h). Then, if the seat belt is still unfastened, the buzzer
will sound in a different tone for 20 more seconds.
*3: Vehicles without navigation system
*4: Vehicles with navigation system
■ Key reminder buzzer (vehic les without smart key system)
The buzzer indicates that the key has not been removed with the engine off
and the driver’s door opened.
■ Open moon roof reminder buzzer (vehicles with mult i-information dis-
play)
The buzzer indicates that the moon roof is not fully closed with the engine off
and the driver’s door opened.
■ 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.
■ Engine oil replacement re minder light (U.S.A. ⎯ vehicles without multi-
information display)
The engine oil replacement reminder ligh t will come on and flash at approxi-
mately 4500 miles (7200 km) after an oil change. When the distance driven
after an oil change exceeds approximately 5000 miles (8000 km), the light
will come on and remain on.
■ Changing the engine oil (U.S.A. only)
Make sure to reset the oil change system. ( →P. 443)
