• When carrying a portable radio, cellular phone, cordless phone or other wireless communication device
●When the vehicle is parked, the time taken for the warning to start or go off could be
extended.
●When tire inflation pressure declines rapidly for example when a tire has burst, the

tire inflation pressure to the specified leve l when the tires are cold, and conduct initial-
ization again.
■When initialization of the tire pressure warning system has failed

When trouble arises
If your Lexus is transported by a flat bed
truck, it should be tied down at the
locations shown in the illustration.
If you use chains or cables to tie down
your vehicle, the angles shaded in black
must be 45 °.
Do not overly tighten the tie downs or
the vehicle may be damaged.
If a tow truck is not available in an emergency, your vehicle may be temporarily
towed using a cable or chain secured to the emergency towing eyelet. 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.

making steering and braking more difficult.
■Wheel nut wrench
Wheel nut wrench is installed in luggage compartment. ( →P. 5 4 8 )
WA R N I N G
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When towing the vehicle
■While towing
●When towing using cables or chains, avoid sudden starts, etc. which place excessive
stress on the eyelet, cables or chains. The towing eyelet, cables or chains may
become damaged, broken debris may hit people and cause serious damage.
●Do not turn the power switch off.
This may lead to an accident as the front wheels will be locked by the parking lock.
■Installing towing eyelet to the vehicle
Make sure that towing eyelet is installed securely.
If not securely installed, towing eyelet may come loose during towing.
NOTICE
■To prevent damage to the vehicle when towing using a wheel-lift type truck
When raising the vehicle, ensure adequate ground clearance for towing at the oppo-
site end of the raised vehicle. Without adequate clearance, the vehicle could be dam-
aged while being towed.
■To prevent body damage when towing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
Be sure to transport the vehicle with the front
wheels raised or with all four wheels raised off
the ground. If the vehicle is towed with the front
wheels contacting the ground, the drivetrain
and related parts may be damaged or electric-
ity generated by the operation of the motor
may cause a fire to occur depending on the
nature of the damage or malfunction.

approximately the same amount.
Tighten the wheel nuts until the tapered
portion comes into loose contact with
the disc wheel seat.
Lower the vehicle.
Firmly tighten each wheel nut two or
three times in the order shown in the
illustration.
