■Emergency towing procedureRelease the parking brake.
Shift the shift lever to N.
Put the “ENGINE START STOP” switch in ACCESSORY mode (engine
off) or IGNITION ON mode (engine running).
CAUTION
■Caution while towing
●Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive stress on
the emergency towing eyelets and the cables or chains.
●If the engine is not running, the power assist for the brakes and steering will not
function, making steering and braking more difficult.
NOTICE
■To 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.
This may cause serious damage to the transmission.
■When towing a vehicle without using a towing dolly
(vehicles with a manual transmission)
The “ENGINE START STOP” switch must not be OFF.

Towing with a sling-type truck
CAUTION
■Installing towing eyelets to the vehicle
Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing. This may
lead to accidents that cause serious injury or even death.
NOTICE
■To prevent body damage

Using a flat bed truckIf 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
■To 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.
■To prevent damaging the vehicle
●Do 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.
●When 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
Follow the procedure below to restart the engine after the system is acti-
vated.Switch to ACCESSORY mode or OFF.
Restart the engine.
NOTICE
■Before 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.

Ve h i c l e s p e e d
● To what extent the accelerator pedal was depressed
● To what extent the brake pedal was applied
● To what extent the ECU controlled the condition of the 4 wheels
● Vehicle stability control system diagnostic data
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.
Disclosure of the data
Lexus will not disclose the data recorded in an EDR to a third party
except when:
● An agreement from the vehicle's owner (or the leasing company for a
leased vehicle) is obtained
● Officially requested by the police or other authorities
● Used as a defense for Lexus in a law suit
● Ordered by a court law
However, if necessary Lexus will:
● Use the data for research on Lexus vehicle safety performance
● Disclose 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
● Disclose summarized data cleared of vehicle identification information
to a non-Lexus organization for research purposes
