5-1. Essential information
If your vehicle needs to be towed
Before towing
The following may indicate a problem with your transmission. Contact
your Lexus dealer before towing.
lThe engine is running, but the vehicle will not move.
lThe vehicle makes an abnormal sound.
Emergency towing
If a tow truck is not available, in an emergency your vehicle may be tem-
porarily towed using a cable or chain secured to the emergency towing
eyelet(s). This should only attempted on hard, surfaced roads for short
distances at low speeds.
A driver must be in the vehicle to steer and operate the brakes. The vehi-
cle’s wheels, drive train, axles, steering and brakes must be in good condi-
tion.
Towing eyelets
If towing is necessary, we recommend having your vehicle towed by your
Lexus dealer or a commercial towing service, using a lift-type truck or a flat
bed truck.
Use a safety chain system for all towing, and abide by all state/provincial
and local laws.
If towing from the rear, the vehicle’s front wheels and axles must be in good
condition. (→P. 377)
If they are damaged, use a towing dolly or flat bed truck.

TION ON mode.
CAUTION
nCaution while towing
lUse 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.
lIf the engine is not running, the power assist for the brakes and steering will not
function, making steering and braking more difficult.
NOTICE
nTo prevent causing serious damage to the transmission
(vehicles with an automatic transmission)

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.

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.
