When trouble arises
RX350/270_EERaise 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.
Installing the spare tire
Remove any dirt or foreign matter
from the wheel contact surface.
If foreign matter is on the wheel
contact surface, the wheel nuts
may loosen while the vehicle is in
motion, causing the tire to come
off.

RX350/270_EEFirmly tighten each wheel nut two
or three times in the order shown
in the illustration.
Tightening torque:

■The compact spare tire (if equipped)
●The compact spare tire is identified by the label “TEMPORARY USE ONLY”
on the tire sidewall.
Use the compact spare tire temporarily, and only in an emergency.
●Make sure to check the tire inflation pressure of the compact spare tire.
(→P. 6 1 7 )
■When using the compact spare tire (if equipped)
As the compact spare tire is not equipped with a tire pressure warning valve and
transmitter, low inflation pressure of the spare tire will not be indicated by the tire
pressure warning system. Also, if you replace the compact spare tire after the tire
pressure warning light comes on, the light remains on.
■If you have a flat front tire on a road covered with snow or ice (vehicles with a
compact spare tire)
Install the compact spare tire on one of the rear wheels of the vehicle. Perform the
following steps and fit tire chains to the front tires:
Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of the vehi-
cle.
Fit tire chains to the front tires.
■After completing the tire change (vehicles with tire pressure warning system)
The tire pressure warning system must be reset. (→P. 4 8 5 )

CAUTION
■Using the tire jack
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 flat tire.
Do not use it on other vehicles, and do not use other tire jacks for replacing tires
on this vehicle.
●Always check that the tire jack is securely set to the jack point.
●Do not put any part of your body under the vehicle while it is supported by the
jack.
●Do not start or run the engine while your vehicle is supported 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.
●Vehicles with electronically modulated air suspension: Be sure to turn off the
height control and stop the engine.
Take particular care when lowering the vehicle to ensure that no one working on or
near the vehicle may be injured.

CAUTION
■Replacing a flat tire
●Observe the following precautions.
Failure to do so may result in serious injury:
• Do not touch the disc wheels or the area around the brakes immediately 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.
• Do not attach a heavily damaged wheel ornament, as it may fly off the wheel
while the vehicle is moving.
●Failure to follow these precautions could cause the wheel nuts to loosen and the
tire to fall off, resulting in death or serious injury.
• Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened, leading
to bolt or disc wheel damage. In addition, the oil or grease can cause the
wheel nuts to loosen and the wheel may fall off, causing a serious accident.
Remove any oil or grease from the wheel bolts or wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 103 N
•m (10.5 kgf•m,
76 f t
•lbf) as soon as possible after changing wheels.
• When installing a tire, only use wheel nuts that have been specifically
designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads or bolt
holes of the wheel, have the vehicle inspected by your Lexus dealer or
repairer, or another duly qualified and equipped professional immediately.
■Replacing a flat tire for vehicles with power back door
In cases such as when replacing tires, make sure to turn off the power back door
main switch (→P. 62). Failure to do so may cause the back door to operate uninten-
tionally if the power back door switch is accidentally touched, resulting in hands and
fingers being caught and injured.
