2011 TOYOTA TUNDRA airbag

520 4-1. Maintenance and care
■Caring for leather areas
Toyota recommends cleaning the interior of the vehicle at least twice a year
to maintain the quality of the vehicle’s interior.
■ Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a
sponge or brush to apply the foam. Rub in overlapping circles. Do not apply
water. Excellent results are obtained when keeping the carpet as dry as pos-
sible.
■ Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also
check the belts periodically for excessive wear, fraying or cuts.
CAUTION
■Water in the vehicle
●Do not splash or spill liquid in the vehicle.
Doing so may cause the electrical components etc. to malfunction or catch
fire.
● Do not get any of the SRS components or wiring in the vehicle interior wet.
( P. 120)
Electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or severe injury.
■ Cleaning the interior (esp ecially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect off
the windshield, obstructing the driver’s view and leading to an accident,
resulting in death or serious injury.

5-1. Essential information
Event data recorder
In a crash or a near car crash eventThe 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 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.
