the vehicle is driven on an unpaved road.

When performing initialization, drive on a

paved road if possible. Depending on the

driving environment and condition of the

tires, initialization will be completed in

approximately 10 to 30 minutes. If initializa-

tion is not complete after driving approxi-

mately 10 to 30 minutes, continue driving

for a while. If the inflation of each tire is not

displayed after driving for approximately 1

hour, perform the following procedure.

●

Park the vehicle in a safe place for

approximately 20 minutes. Then drive

straight (with occasional left and right

turns) at approximately 25 mph (40

km/h) or more for approximately 10 to

30 minutes.

However, in the following situations, the tire
inflation pressure will not be recorded and
the system will not operate properly. Per-
form initialization again.

●

When performing initialization, the tire

pressure warning light does not blink 3

times. (Initialization will not occur while

driving)

●

After performing initialization, the tire

pressure warning light blinks for 1 minute

then stays on after driving for about 20

minutes.

If the inflation pressure of each tire is still not
displayed, have the vehicle inspected by
your Lexus dealer.

■

When registering ID codes

●

Initialize the tire pressure warning system

after ID code registration. Initialization is

disabled if the system was initialized

before registration.

●

After ID code registration, the tires are

hot by driving. Initialize the tire pressure

warning system after the tires become

cold.

The tire pressure warning valve and
transmitter is equipped with a unique
ID code. When replacing a tire pres-
sure warning valve and transmitter, it is
necessary to register the ID code.
When registering the ID codes, per-
form the following procedure.

inflation pressure of each tire. Then, the tire

pressure warning light blinks rapidly for

approximately 1 minute and stays on.

Drive the vehicle at 25mph (40
km/h) or more for approximately
10 to 30 minutes.

When registration is completed, the tire

pressure warning light will go off and the

inflation pressure of each tire will be dis-

played on the multi-information display.
The time elapsed before registration is

completed differs according to the driving

condition and environment.

■

Canceling the change wheel set mode

●

If turning the engine switch off when in

the change wheel set mode before driv-

ing, the change wheel set mode is can-

celed.

●

After driving when in the change wheel

set mode, the change wheel set mode

cannot be canceled. To cancel the mode,

perform the procedure for ID code regis-

tration again and turn the engine switch

off before driving.

●

If the change wheel set mode is canceled,

the ID codes that have already been reg-

istered are communicated. When com-

munication is finished, the tire pressure

warning light will turn off.

■

When ID code registration may not

operate properly

●

Do not move the vehicle backward

during registration. Registration is started

again from the beginning and it may take

longer than usual.

●

When another vehicle is running the side

of the vehicle such as in heavy traffic, it

may take longer to detect the vehicle’s

tire pressure warning valves and trans-

mitters.

●

If tire pressure warning valves and trans-

mitters are in the vehicle, the ID codes

may not be registered.

If registration takes long time, perform the
procedure for ID code registration again
after parking the vehicle for 20 minutes.
If the ID codes cannot be registered even
when performing the above procedure,
contact your Lexus dealer.

ing.

●

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 pressure

to be higher after driving as heat is gener-

ated in the tire. Do not reduce tire infla-

tion pressure after driving.

●

Never exceed the vehicle capacity

weight.

Passengers and luggage weight should

be placed so that the vehicle is balanced.

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 mois-

ture may get into the valve and cause an

air leak, resulting in decreased tire infla-

tion pressure.

ing your tires, check that the wheel
nuts are still tight after driving 1000
miles (1600 km).



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 heav-
ily corroded, it should be replaced.
Otherwise, the tire may separate
from the wheel or cause a loss of
handling control.
