■While towing
If the hybrid system is off, the power assist for the brakes and steering will not func-
tion, making steering and braking more difficult.
■Wheel nut wrench
Wheel nut wrench is installed in trunk. ( P. 568, 581)
CAUTION
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 exces-
sive stress on the towing eyelets, cables or chains. The towing eyelets, cables or
chains may become damaged, broken debris may hit people, and cause serious
damage.
●Do not turn the power switch off.
There is a possibility that the steering wheel is locked and cannot be operated.
■Installing towing eyelets to the vehicle
Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing.
Be sure to transport the vehicle with all four
wheels raised off the ground. If the vehicle is
towed with the tires contacting the ground,
the drivetrain or related parts may be dam-
aged, the vehicle may fly off the truck, or
electricity generated by the operation of the
motor may cause a fire to occur depending
on the nature of the damage or malfunction.

NOTICE
■To prevent damage to the vehicle when towing using a wheel-lift type truck
●Do not tow the vehicle from the rear when the power switch is off. The steering
lock mechanism is not strong enough to hold the front wheels straight.
●When raising the vehicle, ensure adequate ground clearance for towing at the
opposite end of the raised vehicle. Without adequate clearance, the vehicle
could be damaged while being towed.
■To prevent damage to the vehicle when towing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
■To prevent damage to the vehicle during emergency towing
Do not secure cables or chains to the suspension components.

LS600h/LS600hL_EE(OM50G20E)
CAUTION
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional. The vehicle
will become extremely unstable during braking, and the ABS system may fail,
which could cause an accident resulting in death or serious injury.
■When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold firmly and
operate using more force than usual.
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause a loss of
vehicle control and result in death or serious injury.
●As the tire inflation pressure may be low when this warning light is illuminated,
stop your vehicle in a safe place as soon as possible and adjust the tire inflation
pressure immediately.
●If the tire pressure warning light comes on even after tire inflation pressure adjust-
ment, it is probable that you have a flat tire. Check the tires. If a tire is flat, change
it with the spare tire and have the flat tire repaired by the nearest any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
●Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could
lose control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
NOTICE
■To ensure the tire pressure warning system operates properly
Do not install tires with different specifications or makers, as the tire pressure warn-
ing system may not operate properly.

■Warning message in radar cruise mode (if equipped)
In the following cases, the warning message may not be displayed even if vehicle-to-
vehicle distance decreases:
●When your vehicle and the vehicle ahead are traveling at the same speed or the
vehicle ahead is traveling more quickly than your vehicle
●When the vehicle ahead is traveling at a very low speed
●Immediately after cruise control speed is set
●At the instant the accelerator pedal is depressed
■The LKA (Lane-Keeping Assist) lane de parture warning function (if equipped)
In the following cases, the warning message will not be displayed even if a lane line is
crossed.
●When the vehicle speed deviates from the operating range of the LKA system
functions
●When the lane lines cannot be recognized
●When the steering wheel is turned as far as necessary to cause the vehicle to
change lanes
■System warning lights
The master warning light does not come on or flash in the following cases. Instead, a
separate system warning light will come on or flash along with the message shown
on the multi-information display.
●Malfunction of the brake system
The brake system warning light (red indicator) comes on. ( P. 555)
●Malfunction of the regenerative brake system, electronically controlled brake sys-
tem or electric parking brake
The brake system warning light (yellow indicator) comes on. ( P. 557)
●Malfunction of the ABS
The ABS warning light comes on. ( P. 556)
●Malfunction of the charging system
The charging system warning light comes on. ( P. 556)
●Indicates that a door or the trunk is not fully closed
The open door warning light comes on. ( P. 558)
●High engine coolant temperature
The needle of the engine coolant temperature gauge enters the red zone.

CAUTION
■When fixing the flat tire
●Stop your vehicle in a safe and flat area.
●Do not touch the wheels or the area around the brakes immediately after the
vehicle has been driven.
After the vehicle has been driven, the wheels and the area around the brakes may
be extremely hot. Touching these areas with hands, feet or other body parts may
result in burns.
●Connect the valve and hose securely with the tire installed on the vehicle.
●If the hose is not properly connected to the valve, air leakage may occur or seal-
ant may be sprayed out.
●If the hose comes off the valve while inflating the tire, there is a risk that the hose
will move abruptly due to air pressure.
●After inflation of the tire has completed, the sealant may splatter when the hose is
disconnected or some air is let out of the tire.
●Follow the operation procedure to repair th e tire. If the procedure is not followed,
the sealant may spray out.
●Keep back from the tire while it is being repaired, as there is a chance of it burst-
ing while the repair operation is being performed. If you notice any cracks or
deformation of the tire, turn off the comp ressor switch and stop the repair opera-
tion immediately.
●The kit may overheat if operated for a long period of time. Do not operate the
compressor continuously for more than 35 minutes.
●Parts of the kit become hot during operation. Be careful handling the kit during
and after operation. Do not touch the metal part around the connecting area
between the bottle and compressor. It will be extremely hot.
●Do not attach the vehicle speed warning sticker to an area other than the one
indicated. If the sticker is attached to an area where an SRS airbag is located,
such as the pad of the steering wheel, it may prevent the SRS air bag from operat-
ing properly.

CAUTION
■Driving to spread the liquid sealant evenly
●Drive the vehicle carefully at a low speed. Be especially careful when turning and
cornering.
●If the vehicle does not drive straight or you feel a pull through the steering wheel,
stop the vehicle and check the following:
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If tire inflation pressure is 130 kPa (1.3 kgf/cm2 o r b a r , 1 9
psi) or below, this may indicate severe tire damage.
