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.

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

(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.

5-2. Steps to take in an emergency
CAUTION
nWhen the electric power steering warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, firmly hold and
operate it using more force than usual.
nIf the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause loss of
vehicle control and result in death or serious injury.
lStop your vehicle in a safe place as soon as possible. Adjust the tire inflation pres-
sure immediately.
lIf the tire pressure warning light comes on even after tire inflation pressure adjust-
ment, it is probable that you have a flat tire. Check the tires. If the tire is flat,
change to the spare tire and have the flat tire repaired by the nearest Lexus
dealer.
lAvoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could
lose control of the steering wheel or the brakes.
nIf a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
