The following may indicate a problem with your transmission. Contact your
Lexus dealer before towing.
●The engine is running but the vehicle will not move.
●The vehicle makes an abnormal sound.
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 eye-
let. This should only be 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 vehicle’s
wheels, drive train, axles, steering and
brakes must be in good condition.
If your vehicle needs to be towed
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 flat bed
truck.
Use a safety chain system for all towing, and abide by all state/provincial and
