WARNING

■

When cleaning the windshield

Set the wiper switch to off.

If the wiper switch is in “AUTO”, the wip-

ers may operate unexpectedly in the fol-

lowing situations, and may result in hands 

being caught or other serious injuries 

and cause damage to the wiper blades.

Off

AUTO

●

■

Precautions regarding the exhaust 

pipes

Exhaust gasses cause the exhaust pipes 

to become quite hot.
When washing the vehicle, be careful not 

to touch the pipes until they have cooled 

sufficiently, as touching hot exhaust pipes 

can cause burns.

■



Remove dirt and dust using a vac-
uum cleaner. Wipe dirty surfaces 
with a cloth dampened with luke-
warm water.



If dirt cannot be removed, wipe it off 
with a soft cloth dampened with 
neutral detergent diluted to approx-
imately 1%.
Wring out any excess water from 
the cloth and thoroughly wipe off 
remaining traces of detergent and 
water.

■

Shampooing the carpets

There are several commercial foaming-

type cleaners available. Use a sponge or 

brush to apply the foam. Rub in overlapping 

circles. Do not use water. Wipe dirty sur-

faces and let them dry. Excellent results are 

obtained by keeping the carpet as dry as 

possible.

■

Handling the seat belts

Clean with mild soap and lukewarm water 

using a cloth or sponge. Also check the 

belts periodically for excessive wear, fray-

ing or cuts.

NOTICE

■

When using a high pressure car wash

●

WARNING

The engine compartment contains many 

mechanisms and fluids that may move 

suddenly, become hot, or become elec-

trically energized. To avoid death or seri-

ous injury, observe the following 

precautions.

■

When working on the engine com-

partment

●

Keep hands, clothing and tools away 

from the moving fan and engine drive 

belt.

●

Be careful not to touch the engine, 

engine radiator, exhaust manifold, etc., 

right after driving as they may be hot. 

Oil and other fluids may also be hot.

●

Do not leave anything that may burn 

easily, such as paper and rags, in the 

engine compartment.

●

Do not smoke, cause sparks or expose 

an open flame to fuel or the battery. 

Fuel and battery fumes are flammable.

●

Be extremely cautious when working 

on the battery. It contains poisonous 

and corrosive sulfuric acid.

●

Take care because brake fluid can 

harm your hands or eyes and damage 

painted surfaces. If fluid gets on your 

hands or in your eyes, flush the 

affected area with clean water imme-

diately. If you still experience discom-

fort, consult a doctor.

■

When working near the cooling fan 

or radiator grille

Be sure the engine switch is off. With the 

engine switch in ON, the cooling fan may 

automatically start to run if the air condi-

tioning is on and/or the coolant tempera-

ture is high. (



P.461)

■

When working on or under the vehi-

cle

Do not get under the vehicle with just the 

jack supporting it. Always use automo-

tive jack stands or other solid supports.

Engine oil level rise

If the vehicle is repeatedly driven without 

the engine warmed up, moisture caused by 

dew condensation inside the engine or fuel 

which did not burn mixes into the engine oil, 

resulting in a rise in engine oil level. How-

ever, this is not a malfunction.
For example, the engine become difficult to 

be warmed up in the following situations.

●

When driving a short distance

●

When driving at a low speed

●

When the outside temperature is low

When checking the engine oil, make sure 

that the engine is warmed up. If the engine 

oil level exceeds the refill upper limit mark,

When to replace your vehicle’s tires

Tires should be replaced if:

●

The treadwear indicators are showing on 

a tire.

●

You have tire damage such as cuts, splits, 

cracks deep enough to expose the fabric, 

and bulges indicating internal damage.

●

A tire goes flat repeatedly or cannot be 

properly repaired due to the size or loca-

tion of a cut or other damage.

If you are not sure, consult with your Lexus 

dealer.

■

Tire life

Any tire over 6 years old must be checked 

by a qualified technician even if it has sel-

dom or never been used or damage is not 

obvious.

■

Maximum load of tire

Check that the number given by dividing 

the maximum load by 1.10 of the replace-

ment tire is greater than 1/2 of the Gross 

Axle Weight Ratings (GAWR) of either the 

front axle or the rear axle, whichever is 

greater.
For the GAWR, see the Certification Label. 

For the maximum load of the tire, see the 

load limit at maximum cold tire inflation 

pressure mentioned on the sidewall of the 

tire. (

■

Tire types

●

Summer tires

Summer tires are high-speed perfor-

mance tires best suited to highway driv-

ing under dry conditions. Since summer 

tires do not have the same traction per-

formance as snow tires, summer tires are 

inadequate for driving on snow-covered 

or icy roads. For driving on snow-cov-

ered roads or icy roads, the use of snow 

tires is recommended. When installing 

snow tires, be sure to replace all four 

tires.

●

All season tires

All season tires are designed to provide 

better traction in snow and to be ade-

quate for driving in most winter condi-

tions as well as for use year-round. All 

season tires, however, do not have ade-

quate traction performance compared 

with snow tires in heavy or loose snow. 

Also, all season tires fall short in accelera-

tion and handling performance com-

pared with summer tires in highway 

driving.

●

Snow tires

For driving on snow-covered roads or icy 

roads, we recommend using snow tires. If 

you need snow tires, select tires of the 

same size, construction and load capacity 

as the originally installed tires. Since your 

vehicle has radial tires as original equip-

ment, make sure your snow tires also 

have radial construction. Do not install 

studded tires without first checking local 

regulations for possible restrictions. 

Snow tires should be installed on all 

wheels. (



P.372)

■

If the tread on snow tires wears down 

below 0.16 in. (4 mm)

The effectiveness of the tires as snow tires is 

lost.

WARNING

■

When inspecting or replacing tires

Observe the following precautions to 

prevent accidents.

Failure to do so may cause damage to 

parts of the drive train as well as danger-

ous handling characteristics, which may 

lead to an accident resulting in death or 

serious injury.

●

Do not mix tires of different makes, 

models or tread patterns.

Also, do not mix tires of remarkably 

different treadwear.

●

Do not use tire sizes other than those 

recommended by Lexus.

tion.

Do not fail to initialize the tire pressure 
warning system after tire rotation.

■

When rotating the tires

Make sure that the engine switch is OFF. If 

the tires are rotated while the engine switch 

is in ON, the tire position information will 

not be updated.
If this accidentally occurs, either turn the 

engine switch to OFF and then to ON, or 

initialize the system after checking that the 

tire pressure is properly adjusted.

Your vehicle is equipped with a tire 
pressure warning system that uses tire 
pressure warning valves and transmit-
ters to detect low tire inflation pressure 
before serious problems arise.
The tire pressure warning system of 
this vehicle adopts a 2-type warning 
system



When “Adjust Pressure” is dis-
played (Normal Warning)

The tire pressure warning light comes on 
and a buzzer sounds when the tire inflation 
pressure becomes low due to natural air

The tire pressure detected by the 
tire pressure warning system can be 
displayed on the multi-information 

WARNING

●

Do not mix differently constructed 

tires (radial, bias-belted or bias-ply 

tires).

●

Do not mix summer, all season and

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

When initialization is complete, the infla-

tion pressure of each tire will be displayed 

on the multi-information display.
Even if the vehicle is not driven at approxi-

mately 25 mph (40 km/h) or more, initial-

ization can be completed by driving for a 

long time. However, if initialization does 

not complete after driving for 1 hour or 

more, park the vehicle in a safe place for 

approximately 20 minutes and then drive 

the vehicle again.

■

When initializing

●

Initialization is performed while driving at 

a vehicle speed of approximately 25 mph 

(40 km/h) or more.

●

Make sure to carry out initialization after 

adjusting the tire inflation pressure. Also, 

make sure the tires are cold before carry-

ing out initialization or tire inflation pres-

sure adjustment.

●

The tire pressure warning system can be 

initialized by yourself, but depending on 

the driving conditions and driving envi-

ronment, initialization may take some 

time to complete.

■

The initialization operation

●

If you have accidentally turned the engine 

switch to OFF during initialization, it is not 

necessary to restart the initialization 

again as initialization will restart automat-

ically when the engine switch has been 

turned to ON for the next time.

●

If you accidentally perform initialization 

when initialization is not necessary, adjust 

the tire inflation pressure to the specified 

level when the tires are cold, and conduct 

initialization again.

●

While the position of each tire is being 

determined and the inflation pressures 

are not being displayed on the multi-

information display, if the inflation pres-

sure of a tire drops, the tire pressure 

warning light will come on.

Before performing ID code registration, 

make sure that no wheels with tire pres-

sure warning valve and transmitters 

installed are near the vehicle.

●

Make sure to initialize the tire pressure 

warning system after registering the ID 

codes. If the system is initialized before 

registering the ID codes, the initialized 

values will be invalid.

●

As the tires will be warm when registra-

tion is completed, make sure to allow the 

tires to cool before performing initializa-

tion.

●

ID codes can be registered by yourself, 

but depending on the driving conditions

Tire pressure gauge

1

Remove the tire valve cap.

2

Press the tip of the tire pressure 
gauge onto the tire valve.

3

Read the pressure using the gauge 
gradations.

4

If the tire inflation pressure is not at 
the recommended level, adjust the 
pressure.
If you add too much air, press the 
center of the valve to deflate.

5

After completing the tire inflation 
pressure measurement and adjust-
ment, apply soapy water to the 
valve and check for leakage.

6

Put the tire valve cap back on.

■

Tire inflation pressure check interval

You should check tire inflation pressure 

every two weeks, or at least once a month. 

Do not forget to check the spare.

■

Effects of incorrect tire inflation pres-

sure

Driving with incorrect tire inflation pressure 

may result in the following:

●

Reduced fuel economy

●

Reduced driving comfort and poor han-

dling

●

Reduced tire life due to wear

●

Reduced safety

●

Damage to the drive train

If a tire needs frequent refilling, have it 

checked by your Lexus dealer.

■

Instructions for checking tire inflation 

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 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 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.

B

WARNING

■

Proper inflation is critical to save tire 

performance

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.)
