If your vehicle needs to be towed
Before towing
The following may indicate a problem with your transmission.
Contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional, 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 temporarily towed using a cable or chain secured to the emer-
gency towing eyelet. This should only be attempted on hard, sur-
faced roads for short distances at low speeds.
A driver must be in the vehicle to steer and operate the brakes. The
vehicle’s wheels, drive train, axles, steering and brakes must be in
good condition.
If towing is necessary, we recommend having your vehicle towed by
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, such as 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/provin-
cial and local laws.
If towing from the rear, the vehicle's front wheels and axles must be in
good condition. (P. 421)
If they are damaged, use a towing dolly or flat bed truck.
