5-1. Essential information
Using a flat bed truck
If your Lexus is transported by a
flat bed truck, it should be tied
down at the locations shown in the
illustration.
If you use chains or cables to tie
down your vehicle, the angles
shaded in black must be 45°.
Do not overly tighten the tie downs
or the vehicle may be damaged.
NOTICE
nTo prevent causing serious damage to the transmission
(vehicles with an automatic transmission)
Never tow this vehicle from the front with the rear wheels on the ground.
nTo prevent damaging the vehicle
lDo not tow the vehicle from the rear with the “ENGINE START STOP” switch
OFF.
The steering lock mechanism is not strong enough to hold the front wheel
straight.
lWhen raising the vehicle from the rear, ensure adequate ground clearance for
towing at the opposite end of the raised vehicle. Without adequate clearance, the
vehicle could be damaged while being towed from the rear.

Fuel pump shut off system
NOTICE
nBefore starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked on to the ground, the fuel system has been damaged
and is in need of repair. Do not restart the engine.
To minimize the risk of fuel leakage when the engine stalls or an airbag
inflates upon collision, the fuel pump shut off system stops supplying fuel to
the engine.
Follow the procedure below to restart the engine after the system is
activated.
Turn the “ENGINE START STOP” switch to the ACCESSORY
mode or OFF.
Restart the engine.

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 following infor-
mation:
lEngine speed
lWhether the brake pedal was applied or not
lVehicle speed
lTo what extent the accelerator pedal was depressed
lPosition of the transmission shift lever
lWhether the driver and front passenger wore seat belts or not
lDriver's seat position
lSRS airbag deployment data
lSRS airbag system diagnostic data
lFront passenger’s occupant classification
The information above is intended to be used for the purpose of improv-
ing 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.

382
5-1. Essential information
Disclosure of the data
Lexus will not disclose the data recorded in an EDR to a third party
except when:
lAn agreement from the vehicle's owner (or the leasing company for a
leased vehicle) is obtained
lOfficially requested by the police or other authorities
lUsed as a defense for Lexus in a law suit
lOrdered by a court law
However, if necessary Lexus will:
lUse the data for research on Lexus vehicle safety performance
lDisclose the data to a third party for research purposes without dis-
closing details of the vehicle owner, and only when it is deemed neces-
sary
lDisclose summarized data cleared of vehicle identification information
to a non-Lexus organization for research purposes
