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.
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 towing dolly or flat bed truck.

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. Always use caution for the
surroundings and other vehicles while towing.
●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.

NOTICE
■To prevent causing serious damage to the 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 with the “ENGINE START STOP” switch is OFF.
The steering lock mechanism is not strong enough to hold the front wheel
straight.
●When raising the vehicle, 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.

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 following infor-
mation:
● Engine speed
● Whether the brake pedal was applied or not
● Ve h i c l e s p e e d
● 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 troubleshooting, there is a system to record
data in a crash or a near car crash event. This is called an Event Data
Recorder (EDR).
