10 If the specified tire inflation pres-
sure of the wheel set installed
differs from that of the previous
set, it will be necessary to per-
form the tire inflation pressure
setting procedure of the tire
pressure warning system.
If the specified tire inflation pressure is
the same, it will not be necessary to perform the tire inflation pressure set-ting procedure.
11 Register the position of each
wheel.
 Stop the vehicle in a safe place
on a hard, flat surface.
 Set the parking brake.
 Shift the shift position to P.
 Turn off the intrusion sensor and

When raising your vehicle with
a jack, position the jack cor-
rectly.
Improper placement may dam-
age your vehicle or cause

WARNING
■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 pur-pose other than replacing tires or installing and removing tire chains.
●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 sup-
ported by the jack.

1Chock the tires.
2 Slightly loosen the wheel bolts
(one turn).
3 Turn the part of the jack by
hand and place the top of the
jack in the position shown in the
illustration.
WARNING
●Do not start the EV 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.

WARNING
■Replacing a flat tire
●Do not touch the disc wheels or the
area around the brakes immedi- ately after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the brakes will be extremely
hot. Touching these areas with hands, feet or other body parts while changing a tire, etc. may
result in burns.
●Failure to follow these precautions
could cause the wheel bolts to loosen and the tire to fall off, result-ing in death or serious injury.
• Never apply oil or grease to the
wheel bolts or their contact surface
on the wheel .
Doing so may cause the wheel
bolts to be tightened excessively,
leading to damage to the wheel
bolts, the threaded portion the
wheel bolts install to , or the
wheel.
Also, the wheel bolts may come
loose, possibly leading to the wheel
coming off, causing a serious acci-
dent.
If oil or grease is attached to either
of these parts, remove it.
●When installing a wheel, use the
same wheel bolts that were removed with the wheel. Also, do not use any wheel bolts other than
Toyota genuine wheel bolts.
• If a wheel bolt hole in a wheel or the threads of a wheel bolt or the wheel hub are deformed, cracked, rusty or
otherwise damaged, have the vehi- cle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
■When tightening the wheel bolts
Do not tighten the wheel bolts exces- sively.Doing so may cause the wheel bolts,
the threads of the wheel hub, or the wheel to be damaged.
■Replacing a flat tire for vehicles with power back door
In cases such as when replacing tires,
make sure to cancel the power back door system ( P.202). Failure to do so may cause the back door to oper-
ate unintentionally if the power back door switch is accidentally touched, resulting in hands and fingers being
caught and injured.

■Effects of incorrect tire inflation
pressure
Driving with incorrect tire inflation pres- sure may result in the following:
●Reduced electricity consumption effi-ciency
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating, have it checked by any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer.
■Instructions for checking tire infla- tion 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.It is difficult to judge if a tire is properly inflated based only on its appearance.
●It is normal for the tire inflation pres-sure to be higher after driving as heat
is generated in the tire. Do not reduce tire inflation pressure after driving.
●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 pressure should be
checked at least once per
month. However, Toyota rec-
ommends that tire inflation
pressure be checked once
every two weeks.
WARNING
■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 dam-age
●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.
