If your vehicle needs to be towed
Before towing
The following may indicate a problem with your transmission. Contact
your Lexus dealer before towing.
● The engine is running, but the v
ehicle will not move.
● The v
ehicle 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 ch ain secur
ed to the emergency towing
eyelet. This should only attempted on hard, surfaced roads for short dis-
tances at low speeds. 
A driver must be in the vehicle to steer and oper
ate the brakes. The vehi-
cle’s wheels, drive train, axles, steering and br
akes must be in good condi -
tion.
If towing is necessary, we recommen d 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 , a
nd abide by all state/provincial
and local laws.
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.
