If your vehicle needs to be towed
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 temporarily
towed using an elastic towing rope secured to the emergency towing hooks. This
should only be attempted on hard su rfaced 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 an d brakes must be in good condition.
To w i n g h o o k
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.

When trouble arises
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■Caution while towing
●Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving mane uvers which place excessive stress on the
emergency towing hook and the elastic towing rope. Always be cautious of the sur-
roundings and other vehicles while towing.
●Do not turn the engine switch off.
Doing so will lock the steering wheel and pr event operation, possibly causing an acci-
dent and resulting in death or serious injury.
●If the engine is not running, the power assist for the brakes and steering will not func-
tion, making steering and braking more difficult.
