Repair and replacement

It is recommended that genuine Lexus parts

be used for repairs to ensure performance

of each system. If non-Lexus parts are used

in replacement or if a repair shop other than

a Lexus dealer performs repairs, confirm

the warranty coverage.

■

Allow inspection and repairs to be per-

formed by a Lexus dealer

●

Lexus technicians are well-trained spe-

cialists and are kept up to date with the

latest service information. They are well

informed about the operation of all sys-

tems on your vehicle.

●

Keep a copy of the repair order. It proves

that the maintenance that has been per-

formed is under warranty coverage. If any

problem should arise while your vehicle is

under warranty, your Lexus dealer will

promptly take care of it.

General maintenance should be per-
formed on a daily basis. This can be
done by yourself or by a Lexus dealer.

Scheduled maintenance should be
performed at specified intervals
according to the maintenance sched-
ule.

For details about maintenance items and
schedules, refer to the “Warranty and Ser-
vice Guide”, “Owner’s Manual Supple-
ment” or “Scheduled Maintenance”.

Engine oil consumption

A certain amount of engine oil will be con-

sumed while driving. In the following situa-

tions, oil consumption may increase, and

engine oil may need to be refilled in

between oil maintenance intervals.

●

When the engine is new, for example

directly after purchasing the vehicle or

after replacing the engine

●

If low quality oil or oil of an inappropriate

viscosity is used

●

time, or when driving frequently through

heavy traffic

: Vehicles with towing package

■

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 performance
tires best suited to highway driving under
dry conditions. Since summer tires do not
have the same traction performance as
snow tires, summer tires are inadequate for
driving on snow-covered or icy roads. For

driving on snow-covered roads or icy
roads, the use of snow tires is recom-
mended. 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 adequate
for driving in most winter conditions as well
as for use year-round. All season tires,
however, do not have adequate traction
performance compared with snow tires in
heavy or loose snow. Also, all season tires
fall short in acceleration and handling per-
formance compared 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 regula-
tions for possible restrictions. Snow tires
should be installed on all wheels. (

P.374)

■

If the tread on snow tires wears down

below 0.16 in. (4 mm)

The effectiveness of the tires as snow tires is

lost.

■

Checking the tire valves

When replacing the tires, check the tire

valves for deformation, cracks, and other

damage.

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.

●

Do not mix differently constructed

tires (radial, bias-belted or bias-ply

tires).

●

Do not mix summer, all season and

snow tires.

●

Do not use tires that have been used

on another vehicle.

Do not use tires if you do not know

how they were used previously.

●

Do not tow if your vehicle has a spare

tire installed.

NOTICE

■

Driving on rough roads

Take particular care when driving on

roads with loose surfaces or potholes.

These conditions may cause losses in tire

inflation pressure, reducing the cushion-

ing ability of the tires. In addition, driving

on rough roads may cause damage to

the tires themselves, as well as the vehi-

cle’s wheels and body.

■

If tire inflation pressure of each tire

becomes low while driving

Do not continue driving, or your tires

and/or wheels may be ruined.

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 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

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 an accident and resulting in

death or serious injury. Remove any oil or

grease from the wheel bolts or wheel

nuts.

■

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

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.
