CAUTION
When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drivetrain as well as danger-
ous handling characteristics, which may lead to an accident resulting in death
or serious injury.
Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
Do not use tire sizes other than those recommended by Lexus.
Do not mix differently constructed tires (radial, bias-belted or bias-ply tires).
Do not mix summer, all season and snow tires.
Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
Vehicles with an emergency tire puncture repair kit: Do not tow anything if a
tire that has been repaired using the emergency tire puncture repair kit is
installed. The load on the tire may cause unexpected damage to the tire.
When initializing the tire pressure warning system
Do not operate the tire pressure warning reset switch without first adjusting the
tire inflation pressure to the specified level. Otherwise, the tire pressure warn-
ing light may not come on even if the tire inflation pressure is low, or it may
come on when the tire inflation pressure is actually normal.

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 transmitters 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 warn-
ing valves could be bound.
When replacing tire valve caps, do not use tire valve caps other than those
specified. 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
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional or other qualified service shop as soon as possible. Make sure to
replace the tire pressure warning valve and transmitter when replacing the tire.
(P. 451)
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 cush-
ioning ability of the tires. In addition, driving on rough roads may cause dam-
age to the tires themselves, as well as the vehicle’s wheels and body.
Low profile tires (except 16-inch tires)
Low profile tires may cause greater damage than usual to the tire wheel when
sustaining impact from the road surface. Therefore, pay attention to the follow-
ing:
Be sure to use proper tire inflation pressure. If tires are under-inflated, they
may be damaged more severely.
Avoid potholes, uneven pavement, curbs and other road hazards. Failure to do
so may lead to severe tire and wheel damage.
If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Stop the vehicle on a hard, flat surface.
Set the parking brake.
Shift the shift lever to P.
Stop the hybrid system.
Replacing the tire (vehicles with a jack)
When raising your vehicle with a jack, position the jack correctly.
Improper placement may damage your vehicle or cause injury.

CAUTION
Using the tire jack
Observe the following precautions.
Improper use of the tire jack may cause the vehicle to suddenly fall off the jack,
leading to death or serious injury.
Do not use the tire jack for any purpose other than replacing tires or installing
and removing tire chains.
Only use the tire jack that comes with this vehicle for replacing a tire.
Do not use it on other vehicles, and do not use other tire jacks for replacing
tires on this vehicle.
Put the jack properly in its jack point.
Do not put any part of your body under the vehicle while it is supported by the
jack.
Do not start the hybrid system or drive the vehicle while the vehicle is sup-
ported by the jack.
Do not raise the vehicle while someone is inside.
When raising the vehicle, do not put an object on or under the jack.
Do not raise the vehicle to a height greater than that required to replace the
tire.
Use a jack stand if it is necessary to get under the vehicle.
When lowering the vehicle, make sure that there is no-one near the vehicle. If
there are people nearby, warn them vocally before lowering.

Chock the tires.
Slightly loosen the wheel nuts
(one turn).
Turn the tire jack portion “A” by
hand until the notch of the jack is
in contact with the jack point.
The jack point guides are located
under the rocker panel. They indi-
cate the jack point positions.

Raise the vehicle until the tire is
slightly raised off the ground.
Remove all the wheel nuts and
the tire.
When resting the tire on the ground,
place the tire so that the wheel
design faces up to avoid scratching
the wheel surface.

CAUTION
Replacing a tire
Observe the following precautions to reduce the risk of death or serious injury.
Have the wheel nuts tightened with a torque wrench to 103 N•m (10.5 kgf•m,
76 ft•lbf) as soon as possible after changing wheels.
Failure to follow these precautions could cause the nuts to loosen and the
wheel may fall off, which could lead to an accident causing death or serious
injury.
Do not attach a heavily damaged wheel ornament, as it may fly off the wheel
while the vehicle is moving.

IS300h_EE(OM53B95E)
Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
If foreign matter is on the wheel con-
tact surface, the wheel nuts may
loosen while the vehicle is in
motion, causing the tire to come off.
Install the spare tire and loosely tighten each wheel nut by hand by
approximately the same amount.
Turn the wheel nuts until the
washers come into contact with
the disc wheel.
Lower the vehicle.
Firmly tighten each wheel nut
two or three times in the order
shown in the illustration.
Tightening torque:

Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
Reduced fuel efficiency
Reduced driving comfort and tire life
Reduced safety
Damage to the drivetrain
If a tire needs frequent inflating, have it checked by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional.
Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been driven for
more than 1.5 km or 1 mile, you will get an accurate cold tire inflation pressure
reading.
Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation pressure
that is even just a few pounds off can affect ride quality and handling.
Do not reduce tire inflation pressure after driving. It is normal for tire inflation
pressure to be higher after driving.
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is balanced.
Tire inflation pressure
Make sure to maintain proper tire inflation pressure. Tire inflation pres-
sure should be checked at least once per month. However, Lexus recom-
mends that tire inflation pressure be checked once every two weeks.
