(d) Emergency towingIf towing is necessary, we recommend you to have it done
by your Lexus dealer or a commercial tow truck service.
If towing service is not available in an emergency, your
vehicle may be temporarily towed by a cable or chain
secured to the emergency towing eyelet. Use extreme
caution when towing the vehicle.
NOTICE
Only use specified towing eyelet; otherwise your
vehicle may be damaged.
Never tow a vehicle from the rear with four wheels on
the ground. This may cause serious damage to the
transmission.
A driver must be in the vehicle to steer it and operate the
brakes.Towing in this manner may be done only on hard-surfaced
roads for a short distance and at low speeds. Also, the wheels,
axles, drive train, steering and brakes must all be in good
condition.

CAUTION
Use extreme caution when towing the vehicle. Avoid
sudden starts or erratic driving maneuvers which would
place excessive stress on the emergency towing eyelet
and towing cable or chain. The eyelet and towing cable
or chain may break and cause serious injury or damage.
NOTICE
Use only a cable or chain specifically intended for use
in towing vehicles. Securely fasten the cable or chain
to the towing eyelet provided.
Before towing, check that the center differential is unlocked.
(The indicator light must be off with the ignition on.) Release
the parking brake and put the transmission in Nº. The ignition
key must be in ACCº (engine off) or ONº (engine running).
CAUTION
If the engine is not running, the power assist for the
brakes and steering will not work so steering and
braking will be much harder than usual.
Emergency towing hook precautions:
Before emergency towing, check that the eyelet is not
broken or damaged and that the installation bolts are not
loose.
Fasten the towing cable or chain securely to the hook.
Do not jerk the eyelet. Apply steady and even force.
To avoid damaging the eyelet, do not pull from the side or at
a vertical angle. Always pull straight ahead.
