5-2. Steps to take in an emergency
The tire pressure warning system may become inoperative in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
●If electronic devices or facilities using similar radio wave frequencies are nearby.
●If a radio set at similar frequencies is in use in the vehicle.
●If a window tint that affects the radio wave signals is installed.
●If there is a lot of snow or ice on the vehicle, in particular around the wheels or
wheel housings.
●If non-genuine Lexus wheels are used. (Even if you use genuine Lexus wheels,
the tire pressure warning system may not work properly with some types of
tires.)
●If tire chains are used.
●If the spare tire is in a location subject to poor radio wave signal reception.
● If a large metallic object which can interfere with signal reception is put in the
luggage compartment.
■If the tire pressure warning light comes on after blinking for 1 minute frequently
If the tire pressure warning light comes on after blinking for 1 minute frequently
when the engine switch is turned to the “ON” position, have it checked by your
Lexus dealer.
■After changing the engine oil (U.S.A. only)
Make sure to reset the oil maintenance data. (→P. 3 2 6 )
CAUTION
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause loss of
vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pres-
sure 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 the tire is flat,
change to the spare tire and have the flat tire repaired by the nearest Lexus
dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could
lose control of the steering wheel or the brakes.

CAUTION
■Replacing a flat tire
Observe the following precautions to reduce the risk of injury.
●Lower the spare tire completely to the ground before removing it from under the
vehicle.
●Do not try to remove the wheel ornament by hand. Take due care in handling the
ornament to avoid unexpected personal injury.
●Never use oil or grease on the wheel bolts or wheel nuts.
The oil or grease can cause the wheel nuts to loosen, causing a serious accident.
Remove any oil or grease on the wheel bolts or wheel nuts.
●Have the wheel nuts tightened with a torque wrench to 83 ft•lbf (112 N•m, 11.5
kgf•m) as soon as possible after changing wheels.
Failure to follow these precautions could cause the nuts to loosen and the wheels
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.

Lubrication system
*: 5W-30 is an oil that provides optimal levels of fuel efficiency.
Oil viscosity:
● The 5W portion of the oil viscosity rating indicates the characteristic of
the oil which allows cold startability. Oils with a lower value before the W
allow for easier starting of the engine in cold weather.
● The 30 in 5W-30 indicates the oil viscosity when the oil is as its operating
temperature. An oil with a higher viscosity may be better suited if the
vehicle is operated at high speeds, or under extreme load conditions.
