NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves, transmitters
and tire valve caps
●When removing or fitting the wheels, tires or the tire pressure warning valves and
transmitters, contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional as the tire pressure warning valves and trans-
mitters may be damaged if not handled correctly.
●Make sure to install the tire valve caps. If the tire valve caps are not installed,
water could enter the tire pressure warning valves and the tire pressure warning
valves could be bound.
●When replacing tire valve caps, do not use tire valve caps other than those speci-
fied. The cap may become stuck.
■To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve and
transmitter may not operate properly. If a liquid sealant is used, contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped professional
or other qualified service shop as soon as possible. After use of liquid sealant,
make sure to replace the tire pressure warning valve and transmitter when repair-
ing or replacing the tire. ( P. 508)
■Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the cushion-
ing ability of the tires. In addition, driving on rough roads may cause damage to the
tires themselves, as well as the vehicle’s wheels and body.
■If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

LS600h/LS600hL_EE(OM50G20E)
CAUTION
■Proper inflation is critical to save tire performance
Keep your tires properly inflated.
If the tires are not properly inflated, the following conditions may occur which
could lead to an accident resulting in death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from overheated tires
●Air leaking from between tire and wheel
●Wheel deformation and/or tire damage
●Greater possibility of tire damage while driving (due to road hazards, expansion
joints, sharp edges in the road, etc.)
NOTICE
■When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or moisture may get into the valve and cause an air
leak, resulting in decreased tire inflation pressure.

Maintenance and care
LS600h/LS600hL_EE(OM50G20E)
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width and
inset*.
Replacement wheels are available at any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
*: Conventionally referred to as “offset”.
Lexus does not recommend using the following:
●Wheels of different sizes or types
●Used wheels
●Bent wheels that have been straightened
●Use only Lexus wheel nuts and wheel nut wrenches designed for use
with your aluminum wheels.
●When rotating, repairing or changing your tires, check that the wheel
nuts are still tight after driving 1600 km (1000 miles).
●Be careful not to damage the aluminum wheels when using tire chains.
●Use only Lexus genuine balance weights or equivalent and a plastic or
rubber hammer when balancing your wheels.
Wheels
If a wheel is bent, cracked or heavily corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause a loss of han-
dling control.

LS600h/LS600hL_EE(OM50G20E)
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and trans-
mitters that allow the tire pressure warning system to provide advance warning in the
event of a loss in tire inflation pressure. Whenever wheels are replaced, tire pressure
warning valves and transmitters must be installed. ( P. 508)
CAUTION
■When replacing wheels
●Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in a loss of handling control.
●Never use an inner tube in a leaking wheel which is designed for a tubeless tire.
Doing so may result in an accident, causing death or serious injury.
NOTICE
■Replacing tire pressure warn ing valves and transmitters
●Because tire repair or replacement may affect the tire pressure warning valves
and transmitters, make sure to have tires serviced by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional or other qualified
service shop. In addition, make sure to purchase your tire pressure warning
valves and transmitters at any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
●Ensure that only genuine Lexus wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with non-
genuine wheels.

Do not pump the brake pedal repeatedly as this will increase the effort required to
slow the vehicle.
Shift the shift lever to N.
If the shift lever is shifted to N
After slowing down, stop the vehicle in a safe place by the road.
Stop the hybrid system.
If the shift lever cannot be shifted to N
Keep depressing the brake pedal wi th both feet to reduce vehicle
speed as much as possible.
To stop the hybrid system, press
and hold the power switch for 2
consecutive seconds or more, or
press it briefly 3 times or more in
succession.
Stop the vehicle in a safe place by the road.

The following may indicate a problem with your transmission. Contact any
authorized Lexus dealer or repairer, or another duly qualified and
equipped professional or commercial towing service before towing.
●A warning message for the hybrid system is shown on the multi-infor-
mation display and the vehicle does not move.
●The vehicle makes an abnormal sound.
If your vehicle needs to be towed
If towing is necessary, we recommen d having your vehicle towed by any
authorized Lexus dealer or repairer, or another duly qualified and

If your vehicle is transported by a
flatbed truck, it should be tied down
at the locations shown in the illustra-
tion.
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 tempo-
rarily towed using cables or chains secured to the emergency towing eye-
lets. This should only be attempted on hard surfaced roads for short
distances at under 30 km/h (18 mph).
A driver must be in the vehicle to steer and operate the brakes. The vehi-
cle’s wheels, drive train, axles, steering and brakes must be in good condi-
tion.
