CHECKING BRAKE FLUID

63X001b

To check the fluid level, simply look at the see-through reservoir. The level should be between the “MAX” and “MIN” lines on the tank.

It is normal for the brake fluid level to go down slightly as the brake pads wear or when the fluid level in the accumulator is high.

If the reservoir needs frequent refilling, it may indicate a serious mechanical problem.

If the level is low, add FMVSS No.116 DOT 3 or SAE J1703 brake fluid to the brake reservoir.

Refilling brake fluid:

1. Turn the ignition switch off.

2. Depress the brake pedal more than 40 times.

3. Remove the reservoir cap by hand. Add brake fluid up to the “MAX” line.

If you do not follow the procedure above, the reservoir may overflow.

Use only newly opened brake fluid. Once opened, brake fluid absorbs moisture from the air, and excess moisture can cause a dangerous loss of braking efficiency.

CAUTION

Take care when filling the brake fluid reservoir because brake fluid can harm your hands or eyes. If fluid gets on your hands or in your eyes, flush the affected area with clean water immediately. If you still feel uncomfortable with your hands or eyes, go to the doctor.

NOTICE

If you spill some of the fluid, be sure to wipe it off to prevent it from damaging the parts or paintwork.

CHASSIS

The recommended cold tire inflation pressures, tire size and the combined weight of occupants and cargo (vehicle capacity weight) are described on the tire and loading information label.

You should check the tire inflation pressure every two weeks, or at least once a month. And do not forget the spare! The pressure for the spare tire should be 220 kPa (2.2 kgf/cm

The following instructions for checking tire inflation pressure should be observed:

 The inflation pressure should be checked only

when the tires are cold. If your vehicle has been

parked for at least 3 hours and has not been driven for more than 1.5 km or 1 mile since, you will get an

accurate cold tire inflation pressure reading.

 Always use a tire pressure gauge. The appearance

of the tire can be misleading. Besides, tire inflation pressures that are even just a few pounds off can

degrade ride and handling.

 Do not bleed or reduce tire inflation pressure after

Uniform tire quality grading

This information has been prepared in accordance with regulations issued by the National Highway Traffic Safety Administration of the U.S. Department of Transportation. It provides the purchasers and/or prospective purchasers of Lexus vehicles with information on uniform tire quality grading.

Your Lexus dealer will help answer any questions you may have as you read this information.

DOT quality grades - All passenger vehicle tires must conform to Federal Safety Requirements in addition to these grades. Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A

Treadwear - The treadwear grade is a comparative

rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and a half (1 - 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.

Traction AA, A, B, C

- The traction grades, from highest

to lowest, are AA, A, B and C, and they represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.

Warning: The traction grade assigned to this tire is based on braking (straight ahead) traction tests and does not include cornering (turning) traction.

Temperature A, B, C - The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.

Warning: The temperature grades for this tire are established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.

TYPES OF TIRES

Determine what kind of tires your vehicle is originally equipped with.

1. Summer tires

Summer tires are high-speed capability 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 or icy roads, we recommend using snow tires. If installing snow tires, be sure to replace all four tires.

2. 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 all 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 an d handling performance compared with summer tires in highway driving.

The details about how to distinguish summer tires from all season tires are described on page 419.

CAUTION

 Do not mix summer and all season tires on your

vehicle as this can cause dangerous handling characteristics, resulting in loss of control.

 Do not use tires other than the manufacturer’s

designated tires, and never mix tires or wheels of the sizes different from the originals as this could result in loss of control and could cause death or serious injury.

427

CHASSIS

ROTATING TIRES

63L020a

To equalize tire wear and help extend tire life, Lexus recommends that you rotate your tires according to the maintenance schedule. (For scheduled maintenance information, please refer to the “Owner’s Manual Supplement / Scheduled Maintenance”.) However, the most appropriate timing for tire rotation may vary according to your driving habits and road surface conditions.

The wheel assemblies must be rotated as illustrated above.

When rotating tires, check for uneven wear and damage. Abnormal wear is usually caused by incorrect tire inflation pressure, improper wheel alignment, out-of-balance wheels, or severe braking.

Before storing radial, snow or studded tires, mark the direction of rotation and be sure to install them in the same direction when using them again. Tires should be stored in a cool dry place.

New tread 2Tread wear indicator

Worn tread

Replace the tires when tread wear indicators show. The location of tread wear indicators is shown by the “TWI” or “∆” marks, etc., molded on the sidewall of each tire.

The tires on your Lexus have built- in tread wear indicators to help you know when the tires need replacement. When the tread depth wears to 1.6 mm (0.06 in.) or less, the indicators will appear. If you can see the indicators in two or more adjacent grooves, the tire should be replaced.

The effectiveness of snow tires is lost if the tread wears down below 4 mm (0.16 in.).

If you have tire damage such as cuts, splits, cracks deep enough to expose the fabric, or bulges indicating internal damage, the tire should be replaced.

If a tire often goes flat or cannot be properly repaired due to the size or location of a cut or other damage, it should be replaced. If you are not sure, consult with your Lexus dealer.

If air loss occurs while driving, do not continue driving. Driving even a short distance can damage a tire beyond repair.

Any tires which are over 6 years old must be checked by a qualified technician even if damage is not obvious.

Tires deteriorate with age even if they have never or seldom been used.

This also applies to the spare tire and tires stored for future use.

429

CHASSIS

Tire selection

When replacing a tire, use a tire of the same size and construction, and the same or greater maximum load as the originally installed tires. Also, all the tires must be the same brand and have the same tread patterns.

Using any other size or type of tire may seriously affect handling, ride, speedometer/odometer calibration, ground clearance, and clearance between the body and tires or snow chains.

Check that the maximum load of the replaced 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. As for the maximum load of the tire, see the load limit at maximum cold tire inflation pressure mentioned on the sidewall of the tire, and as for the Gross Axle Weight Ratings (GAWR), see the Certification Label. For details about the Certification Label and sidewall of the tire, see pages 386 and 419.

CAUTION

Observe the following instructions. Otherwise, an accident may occur resulting in death or serious injuries.

 Do not mix radial, bias belted, or bias-ply tires

on your vehicle, as this may cause dangerous handling characteristics resulting in loss of control.

 Do not use tires other than the manufacturer’s

recommended size, as this may cause dangerous handling characteristics resulting in loss of control.

 Do not use tires of different brands, sizes,

construction or tread patterns, as this may cause dangerous handling characteristics resulting in loss of control.

It can cause dangerous handling characteristics, resulting in loss of control. If you need to change from conventional tires to radial tires or vice versa, replace them as a set.

CHASSIS

INSTALLING SNOW TIRES AND

CHAINS

When to use snow tires or chains

Snow tires or chains are recommended when driving on snow or ice.

On wet or dry roads, conventional or radial tires provide better traction than snow or studded tires.

Snow tire selection

If you need snow tires, select tires of the same size, construction and load capacity as the originally installed tires. Also, all the tires must be the same brand and have the same tread patterns.

Do not use tires other than stated above. Since your vehicle has radial tires as original equipment, make sure your snow tires also have radial construction. Do not install studded tires without first checking local regulations for possible restrictions.

CAUTION

Observe the following instructions. Otherwise, an accident may occur resulting in death or serious injuries.

 Do not use snow tires other than the manufacturer’s

recommended size, as this may cause dangerous handling characteristics resulting in loss of control.

 Do not use snow tires of different brands, sizes,

construction or tread patterns, as this may cause dangerous handling characteristics resulting in loss of control.

Snow tire installation

Snow tires should be installed on all wheels.

Installing snow tires on the rear wheels only can lead to an excessive difference in road grip capability between the front and rear tires which could cause loss of vehicle control.

CAUTION

 Do not drive with the snow tires incorrectly inflated.  Never drive over 105 km/h (65 mph) with any type of

snow tires.

A: Diameter of side chain 3.5 (0.14) B: Diameter of cross chain 4.0 (0.16)

Regulations regarding the use of tire chains vary according to location or type of road. Always check local regulations before installing chains.

NOTICE

If the wrong combination of tire and chain is used, the chains could damage the vehicle body.

Chain installation

Install the chains on the rear tires as tightly as possible. Do not use tire chains on the front tires. Retighten chains after driving 0.5 - 1.0 km (1/4 - 1/2 mile).

When installing chains on your tires, carefully follow the instructions of the chain manufacturer.

CAUTION

 Do not exceed 50 km/h (30 mph) or the chain

manufacturer’s recommended speed limit, whichever is lower.

 Drive carefully avoiding bumps, holes, and sharp

turns, which may cause the vehicle to bounce.

 Avoid sharp turns or locked-wheel braking, as use of

chains may adversely affect vehicle handling.

 When driving with chains installed, be sure to drive

carefully . Slow down before entering curves to avoid losing control of the vehicle. Otherwise an accident may occur.

432

CHASSIS

REPLACING WHEELS

When to replace your wheels

If you have wheel damage such as bending, cracks or heavy corrosion, the wheel should be replaced.

If you fail to replace a damaged wheel, the tire may slip off the wheel or cause loss of handling control.

Replacement with used wheels is not recommended as they may have been subjected to rough treatment or high mileage and could fail without warning. Also, bent wheels which have been straightened may have hidden structural damage and therefore should not be used. Never use an inner tube in a leaking wheel which is designed for a tubeless tire.

Wheel selection

When replacing wheels, care should be taken to ensure that they are equivalent to those removed in load capacity, diameter, rim width, and offset.

Correct replacement wheels are available at your Lexus dealer.

A wheel of a different size or type may adversely affect handling, wheel and bearing life, brake cooling, speedometer/odometer calibration, stopping ability, headlight aim, bumper height, vehicle ground clearance, and tire or snow chain clearance to the body and chassis.

CAUTION

Observe the following instructions. Otherwise, an accident may occur resulting in death or serious injuries.

 Do not use wheels other than the manufacturer’s

recommended size, as this may cause dangerous handling characteristics resulting in loss of control.

 Do not use wheels of different brands, sizes and

 If you have rotated, repaired, or changed your tires, check

that the wheel nuts are still tight after driving 1600 km (1000

miles).

 When using tire chains, be careful not to damage the

aluminum wheels.

 Use only Lexus wheel nuts and wrench designed for your

aluminum wheels.

 When balancing your wheels, use only Lexus balance

weights or equivalent and a plastic or rubber hammer.

 As with any wheel, periodically check your aluminum

wheels for damage. If damaged, replace immediately.

REPORTING SAFETY DEFECTS

If NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety defect exists in a group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in individual problems between you, your dealer, or Toyota Motor Sales, U.S.A., Inc.

To contact NHTSA, you may either call the Auto Safety Hotline toll- free at 1- 800- 424- 9393 (or 366-0123 in Washington, D.C. area) or write to: NHTSA, U.S. Department of Transportation, Washington, D.C. 20590. You can also obtain other information about motor vehicle safety from the Hotline.
