If your vehicle needs to be towed
Before towingThe following may indicate a problem with your automatic transmission.
Contact your Lexus dealer before towing.
● The engine is running, but the vehicle will not move.
● The 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. This should only be attempted on hard, surfaced roads for short
distances at low speeds.
A driver must be in the vehicle to s teer and operate the brakes. The vehi-
cle’s wheels, drive train, axles, steering and brakes must be in good condi-
tion.
If towing is necessary, we recommend having your vehicle towed by your
Lexus dealer or a commercial towing se rvice, 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 wheels and axle on the ground must be in good
condition.
If they are damaged, use a to wing dolly or flat bed truck.

Put the shift lever in “N”.
The “ENGINE START STOP” switch must be in the ACCESSORY mode
(engine off) or the IGNITION ON mode (engine on).
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 eyelet and the cable or chain.
●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 automatic transmission
Never tow this vehicle from the front with the rear wheels (2WD models) or four
wheels (4WD models) on the ground.
This may cause serious damage to the automatic transmission.

Event data recorder
In a crash or a near car crash eventThe SRS airbag sensor assembly cont ains the EDR. In a crash or a near
car crash event, this devic e may record some or all of the following infor-
mation:
● Engine speed
● Whether the brake pedal was applied or not
● Vehicle speed
● To what extent the accelerator pedal was depressed
● Position of the automatic 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
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 troubles hooting, there is a system to record
data in a crash or a near car crash event. This is called an Event Data
Recorder (EDR).
