6-3. Do-it-yourself maintenance

more than 1 mile or 1.5 km, you will get an

accurate cold tire inflation pressure read-

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 gen-

erated 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.

Maintenance and

care

When replacing wheels, care should
be taken to ensure that they are equiv-
alent to those removed in load capac-
ity, diameter, rim width and inset

*

.

Replacement wheels are available at
your Lexus dealer.

*

: Conventionally referred to as offset.

Lexus does not recommend using the
following:
 Wheels of different sizes or types
 Used wheels
 Bent wheels that have been straight-

ened

■

When replacing wheels

The wheels of your vehicle are equipped

with tire pressure warning valves and trans-

mitters that allow the tire pressure warning

system to provide advance warning in the

event of a loss in tire inflation pressure.

Whenever wheels are replaced, tire pres-

sure warning valves and transmitters must

be installed. (

P.321)

 Use only Lexus wheel nuts and

wrenches designed for use with
your aluminum wheels.

 When rotating, repairing or chang-

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

 Vehicles with 17-inch tires: Be care-

ful not to damage the aluminum
wheels when using tire chains.

 Use only Lexus genuine balance

weights or equivalent and a plastic
or rubber hammer when balancing

Wheels

If a wheel is bent, cracked or heavily
corroded, it should be replaced.
Otherwise, the tire may separate
from the wheel or cause a loss of
handling control.

Wheel selection

WARNING

■

When replacing wheels

●

Do not use wheels that are a different

size from those recommended in the

Owner’s Manual, as this may result in a

loss of handling control.

●

Never use an inner tube in a leaking

wheel which is designed for a tubeless

tire. Doing so may result in an acci-

dent, causing death or serious injury.

■

Use of defective wheels prohibited

Do not use cracked or deformed wheels.

Doing so could cause the tire to leak air

during driving, possibly causing an acci-

dent.

NOTICE

■

Replacing tire pressure warning

valves and transmitters

●

Because tire repair or replacement

may affect the tire pressure warning

valves and transmitters, make sure to

have tires serviced by your Lexus

dealer or other qualified service shop.

In addition, make sure to purchase

your tire pressure warning valves and

transmitters at your Lexus dealer.

●

Ensure that only genuine Lexus wheels

are used on your vehicle.

Tire pressure warning valves and trans-

mitters may not work properly with

non-genuine wheels.

matically after operating for approxi-

mately 20 minutes. To manually turn the

emergency flashers off, press the switch

twice.

(The emergency flashers may not turn on

automatically depending on the force of

the impact and conditions of the colli-

sion.)

Steadily step on the brake pedal
with both feet and firmly depress it.

Do not pump the brake pedal repeatedly

as this will increase the effort required to

slow the vehicle.

2

of the vehicle equals the water pres-
sure outside of the vehicle, and then
open the door and exit the vehicle.

WARNING

■

If the engine has to be turned off while

driving

Power assist for the brakes and steering

wheel will be lost, making the brake

pedal harder to depress and the steering

wheel heavier to turn. Decelerate as

much as possible before turning off the

engine.

rising water

In the event the vehicle is sub-
merged in water, remain calm and
perform the following.
