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.
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
flatbed truck.
Use a safety chain system for all towing, and abide by all state/provincial
and local laws.
2WD models: If towing your vehicle with a wheel-lift type truck from the
front, the vehicle's rear wheels and axles must be in good conditions.
(→P. 527, 530)
If they are damaged, use a towing dolly or flatbed truck.
AWD models: If towing your vehicle with a wheel-lift type truck, use a tow-
ing dolly. (→P. 5 2 7 , 5 3 0 )

5-1. Essential information
Event data recorder
In a crash or a near crash event
The SRS airbag sensor assembly contains the EDR. In a crash or near
crash event, this device may record some or all of the following informa-
tion:
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 near crash event.

If the vehicle becomes stuck
CAUTION
nWhen attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the surround-
ing area is clear to avoid striking other vehicles, objects or people. The vehicle may
also lunge forward or lunge back suddenly as it becomes free. Use extreme cau-
tion.
nWhen shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident and resulting in death or serious injury.
NOTICE
nTo avoid damage to the transmission and other components
lAvoid spinning the wheels.
lIf the vehicle remains stuck even after these procedures are performed, the vehi-
cle may require towing to be freed.
Carry out the following procedures if the tires spin or the vehicle becomes
stuck in mud, dirt, or snow:
Stop the engine. Set the parking brake and shift the shift lever
to P.
Remove the mud, snow, or sand from around the stuck tire.
Place wood, stones or some other material under the tires to
help provide traction.
Restart the engine.
AWD models: Active all-wheel drive lock mode (→P. 237)
Shift the shift lever to the D or R position and carefully apply
the accelerator to free the vehicle.
