1. Look carefully at the fuse. If the thin wire is broken, the fuse has blown. If you are not sure or if it is too dark to see, try replacing the suspected fuse with one of the same value that you know is good.

2. Only install a fuse with the amperage rating designated on the fuse box lid.

If you do not have a spare fuse, in an emergency you can pull out the “RADIO NO.1”, “RADIO NO.2” or “PWR OUTLET NO.1” fuse, which may be dispensable for normal driving, and use it if its amperage rating is the same.

If you cannot use one of the same amperage, use one lower than, but as close to the amperage as possible. If the amperage is lower than that specified, the fuse might blow out again but this does not indicate anything wrong. Be sure to get the correct fuse as soon as possible and return the substitute to its original clips.

Page 22

ELECTRICAL COMPONENTS

It is a good idea to purchase a set of spare fuses and keep them in your vehicle for emergencies.

If the new fuse immediately blows out, there is a problem with the electrical system. Have your Lexus dealer correct it as soon as possible.

You should normalize the power back door, power windows and moon roof if they do not work or the jam protection function does not operate correctly after replacing blown fuses. In these cases, you should do the each instructions referring on the following pages.

 Power back door (See page 46.)  Power windows (See page 74.)  Moon roof (See page 147 or 151.)

CAUTION

Never use a fuse with a higher amperage rating, or any other object, in place of a fuse. This may cause extensive damage and possibly a fire.

2. When turning the vertical movement adjusting bolt ( turn the Phillips-head screwdriver to the same direction as step 1. To calculate the correct number of turns, multiply the number of times you turned the screwdriver in step 1 by 1.25. Turn the screwdriver by this amount.

REPLACING LIGHT BULBS

The illustration on the following pages show the locations of light bulbs. If it is necessary to replace a bulb, take your vehicle to your Lexus dealer as soon as possible. Use bulbs with the bulb numbers and wattage ratings given in the table.

The stop lights consist of a number of LEDs. If two or more LEDs burn out, your vehicle may not conform to local laws (SAE). If this occurs, take your vehicle to your Lexus dealer to have the light replaced.

 To prevent burning yourself, do not replace the light

bulbs while they are hot.  Halogen bulbs have pressurized gas inside and

require special handling. They can burst or shatter if

scratched or dropped. Hold a bulb only by its plastic

or metal case. Do not touch the glass part of a bulb

with bare hands. Vehicles with power back door system —  When replacing the rear light bulbs, turn off the

power back door system.

CAUTION

690

Page 28

Vehicles with discharge headlights —  Do not touch the high voltage socket when the low

beam headlight turns on. 20000 V is momentarily generated and may cause severe injury by electric shock.

 Do not disassemble, repair or take apart the low beam

headlight bulbs, connector, power supply circuits and rotated components. Or you may be injured by electric shocks. Call your dealer when the headlights fail to work or have to be replaced or disposed of.

NOTICE

Only use a bulb of the listed type.

ELECTRICAL COMPONENTS

The inside of the lens of exterior lights such as headlights may temporarily fog up when the lens becomes wet in the rain or in a car wash. This is not a problem because the fogging is caused by the temperature difference between the outside and inside of the lens, just like the windshield fogs up in the rain. However, if there is a large drop of water on the inside of the lens, or if there is water pooled inside the light, contact your Lexus dealer.

PROTECTING YOUR VEHICLE

FROM CORROSION

Proper care of your Lexus can help ensure long-term corrosion prevention.

The most common causes of corrosion to your vehicle are:

 The accumulation of road salt, dirt and moisture in

hard-to-reach areas under the vehicle.

 Chipping of paint or undercoating caused by minor

accidents or by stones and gravel.

The following conditions will cause or accelerate corrosion of your vehicle, so it is important to keep your vehicle, particularly the underside, as clean as possible and to repair any damage to paint or protective coatings as soon as possible.

 The presence of road salt or dust control chemicals, salt in

the air near the sea coast, industrial air pollution.

 High humidity, especially at temperatures just above

freezing point.

 Certain parts of your vehicle are wet or damp for an

extended period of time, even though other parts of the vehicle are dry.

 Components of the vehicle which are prevented from

quick-drying due to lack of proper ventilation are exposed to high ambient temperature.

To help prevent corrosion on your Lexus, follow these guidelines:

Keep your vehicle clean by regular washing. In addition,

observe the following points.  If you drive on salted roads in the winter or if you live near

the ocean, you should hose off the undercarriage at least once a month to minimize corrosion.

 High pressure water or steam is effective for cleaning the

vehicle’s underside and wheel housings. Pay particular attention to these areas as it is dif ficult to see all the mud and dirt. It will do more harm than good to simply wet the mud and debris without removing. The lower edge of doors, rocker panels and frame members have drain holes which should not be allowed to clog with dirt as trapped water in these areas can cause corrosion.

 Wash the underside of the vehicle thoroughly when winter

is over. See “Washing and waxing” on page 701 for more tips. Check the condition of your vehicle’s paint and trim. If you

find any chips or scratches in the paint, touch them up immediately to prevent corrosion from starting. If the chips or scratches have gone through the bare metal, have a qualified body shop make the repair.

700

Page 40

BODY

Check the interior of your vehicle. Water and dirt can

accumulate under the floor mats and could cause corrosion. Occasionally check under the mats to make sure the area is dry. Be particularly careful when transporting chemicals, cleansers, fertilizers, salt, etc. These should be transported in proper containers. If a spill or leak should occur, immediately clean and dry the area.

Use mud shields on your wheels. If you drive on salted or gravel roads, mud shields help protect your vehicle. Full-size shields, which come as near to the ground as possible, are the best. We recommend that the fittings and the area where the shields are installed be treated to resist corrosion. Your Lexus dealer will be happy to assist in supplying and installing the shields if they are recommended for your area.

Keep your vehicle in a well ventilated garage or a roofed place. Do not park your vehicle in a damp, poorly ventilated garage. If you wash your vehicle in the garage, or

if you drive it covered with water or snow, your garage may be so damp as to cause corrosion. Even if your garage is heated, a wet vehicle can corrode if the ventilation is poor.

WASHING AND WAXING

Washing your Lexus

Keep your vehicle clean by regular washing.

The following cases may cause weakness to the paint or corrosion to the body and parts. W ash your vehicle as soon as possible.

 When driving in a coastal area  When driving on a road sprinkled with antifreeze  When exposed to coal tar, tree sap, bird droppings and

carcass of an insect

 When driving in areas where there is a lot of smoke, soot,

Hand-washing your Lexus

Work in the shade and wait until the vehicle body is not warm to the touch.

1. Rinse off loose dirt with a hose. Remove any mud or road salt from the underside of the vehicle or the wheel wells.

2. Wash with a mild car-wash soap, mixed according to the manufacturer’s instructions. Use a soft cotton mitt and keep it wet by dipping it frequently into the wash water. Do not rub hard — let the soap and water remove the dirt.

Fuel filler door: Do not apply water (high-pressure car wash,

for example) at or near the fuel tank inlet with the fuel filler door opened. If the water enters the air vent, you may experience trouble with refueling or rough engine idling.

Electronically modulated air suspension: Do not spray a jet of high-pressure water at the air suspension unit, especially the air spring, at an extremely close range. This may damage the air suspension.

Plastic wheel ornaments: The plastic wheel ornaments are damaged easily by organic substances. If any organic substance splash an ornament, be sure to wash them off with water and check if the ornament is damaged.

Aluminum wheels: Use only a mild soap or neutral detergent.

Plastic bumpers and side moldings: Wash carefully. Do not

scrub with abrasive cleaners. The bumper and side molding faces are soft.

Exterior lights: Wash carefully. Do not use organic substances or scrub them with a hard brush. This may damage the surfaces of the lights.

Road tar: Remove with turpentine or cleaners that are marked safe for painted surfaces.

3. Rinse thoroughly — dried soap can cause streaking. In hot weather you may need to rinse each section right after you wash it.

4. To prevent water spots, dry the vehicle using a clean soft cotton towel. Do not rub or press hard — you might scratch the paint.

Leather-trimmed Interior

The selected leather is used in your Lexus. Due to characteristics of leather products, some parts of leather may be rough, uneven or scratched originally.

To keep good appearance, we recommend you to clean it periodically twice a year.

Remove dirt on the leather in the following ways:

1. Wipe it off lightly using a soft cloth (e.g. gauze) dampened with 5% solution of neutral detergent for wool.

2. Wring water from a clean cloth and thoroughly wipe off all traces of detergent with it.

3. Wipe of f th e surface of the leather with a dry soft cloth. Allow the leather to dry in a ventilated shaded area. Excess of wet may cause the hardening or shrinking of the leather.

705

CHECKING BRAKE FLUID

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. So be sure to keep the reservoir filled.

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.

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

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 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.

637

Page 57

CHECKING POWER STEERING

FLUID

The power steering fluid reservoir is located under the engine compartment cover. Before checking the power steering fluid, remove the cover. (For details, see “Removing the engine compartment cover” on page 603.)

CHASSIS

Check the fluid level through the reservoir. If necessary, add automatic transmission fluid DEXRON

If the vehicle has been driven around 80 km/h (50 mph) for 20 minutes (a little more in frigid temperatures), the fluid is hot (60C — 80C or 140F — 175F). You may also check the level when the fluid is cold (about room temperature, 10C — 30C or 50F — 85F) if the engine has not been run for about five hours.

CHECKING TIRE INFLATION

PRESSURE

The recommended cold tire inflation pressures, tire sizes and the combined weight of occupants and cargo (vehicle capacity weight) are described on pages 635 and 698. They are also described on the tire and loading information label as shown.

You should check the tire inflation pressure every two weeks, or at least once a month. And do not forget the spare!

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

 The 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 a tire can be misleading. Besides, tire inflation pressures that are even just a few pounds off can degrade handling and ride.

 Do not bleed or reduce tire inflation pressure

after driving. It is normal for the tire inflation

pressure to be higher after driving.

641

Page 61

CHASSIS

 Never exceed the vehicle capacity weight.

Passengers and luggage weight should be located so that the vehicle is balanced.

Inspection and adjustment procedure



Tire valve

Tire pressure gauge

1. Remove the tire valve cap.

2. Press the tip of the tire pressure gauge to the tire valve.

3. Read the pressure using the graduations of the gauge.

4. In case the tire inflation pressure is not within the prescribed range, insert the compressed air from the valve. In case of applying too much air, press the center of the valve and release the air to adjust.

5.After completing the tire inflation pressure measurement and adjustment, apply soapy water to the valve and check for leakage.

6. Install the tire valve cap. If a gauge and air pump are not available, have your

vehicle checked by your Lexus dealer.

CAUTION

Be sure to reinstall the tire valve caps. Without the valve caps, dirt or moisture could get into the valve core and cause air leakage. If the caps have been lost, have new ones put on as soon as possible.

Incorrect tire inflation pressure may waste fuel, reduce the comfort of driving, reduce tire life and make your vehicle less safe to drive.

If a tire frequently needs refilling, have it checked by your Lexus dealer.

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.

648

Page 68

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 and 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 644.

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.

ROTATING TIRES

To equalize the 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 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.

Initial adjustment of the tire pressure warning system is necessary after you have rotated your tires. See “Tire pressure warning system” on page

513.

CHECKING AND REPLACING TIRES

When to replace your tires



New tread

Worn tread

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

Tread wear indicator

∆” marks,

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.

656

Page 76

CHASSIS

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

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, on four-wheel drive models, 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 Certification Label and sidewall of the tire, see pages 598 and 644.

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.

 Four-wheel drive models:

Do not use tires of different brands, sizes, construction or tread patterns, as this may cause dangerous handling characteristics resulting in loss of control.

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, on four-wheel drive models, 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.

 Four-wheel drive models:

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.

658

Page 78

CHASSIS

Snow tire installation

Snow tires should be installed on all wheels.

Installing snow tires on the front 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

 Snow tires should be inflated to the same pressure as

the original tires.

 Never drive over 120 km/h (75 mph) with any type of

snow tires.

Tire chain selection



Side chain

Use the tire chains of correct size.

For 225/65R17 101S or P235/55R18 99V tires, use the following type chains.

A: Diameter of side chain 3.0 (0.12) B: Width of side chain 10.0 (0.39) C: Length of side chain 30.0 (1.18) D: Width of cross chain 14.0 (0.55) E: Length of cross chain 25.0 (0.98) F: Diameter of cross chain 4.0 (0.16)

CHASSIS

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 front tires as tightly as possible. Do not use tire chains on the rear 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.

660

 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.

 Vehicles with electronically modulated air

suspension: When installing the tire chains, be sure to turn off the height control and stop the engine. Otherwise, the vehicle height may change in the automatic leveling function, resulting in an unexpected accident. For details, see page 497.

If the chains are installed, the tire pressure warning system may not operate properly. See “Tire pressure warning system” on page 513.

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.

 Four-wheel drive models:

Do not use wheels of different brands, sizes and types, as this may cause dangerous handling characteristics resulting in loss of control.

Initial adjustment of the tire pressure warning system is necessary after you have replaced your wheels. See “T ire pressure warning system” on page 513.

ALUMINUM WHEEL PRECAUTIONS

 When installing aluminum wheels, check that the wheel nuts

are tight after driving your vehicle the first 1600 km (1000 miles).

 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

FUEL

Fuel type

Y our vehicle must use only unleaded gasoline.

To help prevent gas station mixups, your Lexus has a smaller fuel tank opening. The special nozzle on pumps with unleaded fuel will fit it, but the larger standard nozzle on pumps with leaded gas will not.

NOTICE

Do not use leaded gasoline. Use of leaded gasoline will cause the three-way catalytic converter to lose its effectiveness and the emission control system to function improperly. Also, this can increase maintenance costs.

At a minimum, the gasoline you use should meet the specifications of ASTM D4814 in the U.S.A. and CGSB

3.5-M93 in Canada.

616

Page 88

ENGINE

Octane rating

Premium unleaded gasoline with an Octane Rating of 91 (Research Octane Number 96) or higher required for optimum engine performance. However, i f such premium type cannot be obtained, you may use unleaded gasoline with an Octane Rating as low as 87 (Research Octane Number 91).

Use of unleaded fuel with an Octane Rating or Research Octane Number lower than stated above will cause persistent heavy knocking. If it is severe, this will lead to engine damage.

If your engine knocks...

If you detect heavy knocking even when using the recommended fuel, or if you hear steady knocking while holding a steady speed on level roads, consult your Lexus dealer.

However, occasionally, you may notice light knocking for a short time while accelerating or driving up hills. This is normal and there is no need for concern.

Gasoline containing detergent additives

Lexus recommends the use of gasoline that contains detergent additives to avoid build-up of engine deposits.

However, all gasoline sold in the U.S. contains detergent additives to keep clean and/or clean intake systems.

Quality gasoline

Automotive manufacturers in the U.S., Europe and Japan have developed a specification for quality fuel named World-W ide Fuel Charter (WWFC) that is expected to be applied world wide. The WWFC consists of four categories that depend on required emission levels. In the U.S., category 4 has been adopted. The WWFC improves air quality by providing for better emissions in vehicle fleets, and customer satisfaction through better vehicle performance.

Cleaner burning gasoline

Cleaner burning gasoline, including reformulated gasoline that contains oxygenates such as ethanol or MTBE is available in many areas.

Lexus recommends the use of cleaner burning gasoline and appropriately blended reformulated gasoline. These types of gasoline provide excellent vehicle performance, reduce vehicle emissions, and improve air quality.

617

Page 89

ENGINE

Oxygenates in gasoline

Lexus allows the use of oxygenate blended gasoline where the oxygenate content is up to 10% ethanol or 15% MTBE. If y o u use gasohol in your Lexus, be sure that it has an octane rating no lower than 91.

Lexus does not recommend the use of gasoline containing methanol.

Gasoline containing MMT

Some gasoline contain an octane enhancing additive called MMT (Methylcyclopentadienyl Manganese Tricarbonyl).

Lexus does not recommend the use of gasoline that contains MMT. If fuel containing MMT is used, your emission control system may be adversely affected. The Malfunction Indicator Lamp on the instrument cluster may come on. If this happens, contact your Lexus dealer for service.

NOTICE



Do not use gasohol other than stated above. It will cause fuel system damage or vehicle performance problems.



If drivability problems are encountered (poor hot starting, vaporizing, engine knock, etc.), discontinue its use.



Take care not to spill gasohol during refueling. Gasohol may cause paint damage.

Gasoline quality

In a very few cases, you may experience driveability problems caused by the particular gasoline that you are using. If you continue to have unacceptable driveability, try changing gasoline brands. If this does not rectify your problem, then consult your Lexus dealer.

FUEL PUMP SHUT OFF SYSTEM

The fuel pump shut off system stops supplying fuel to the engine to minimize the risk of fuel leakage when the engine stalls or an airbag inflates upon collision. To restart the engine after the fuel pump shut off system activates, turn the ignition switch to “ACC” or “LOCK” once and start it.

CAUTION

Inspect the ground under the vehicle before restarting the engine. If you find that liquid has leaked onto the ground, it is the fuel system has been damaged and it is in need of repair. I n this case, do not restart the engine.

FACTS ABOUT ENGINE OIL

CONSUMPTION

Functions of engine oil

Engine oil has the primary function of lubricating and cooling the inside of the engine, and plays a major role in maintaining the engine in proper working order.

Engine oil consumption

It is normal that an engine should consume some engine oil during normal engine operation. The causes of oil consumption in a normal engine are as follows.

 Oil is used to lubricate pistons, piston rings and cylinders.

A thin film of oil is left on the cylinder wall when a piston moves downwards in the cylinder. High negative pressure generated when the vehicle is decelerating sucks some of this oil into the combustion chamber. This oil as well as some part of the oil film left on the cylinder wall is burned by the high temperature combustion gases during the combustion process.

 Oil is also used to lubricate the stems of the intake valves.

Some of this oil is sucked into the combustion chamber together with the intake air and is burned along with the fuel. High temperature exhaust gases also burn the oil used to lubricate the exhaust valve stems.

619

Page 91

ENGINE

The amount of engine oil consumed depends on the viscosity of the oil, the quality of the oil and the way the vehicle is driven.

More oil is consumed under driving conditions such as high speeds and frequent acceleration and deceleration.

A new engine consumes more oil, since its pistons, piston rings and cylinder walls have not become conditioned.

Oil consumption: Max. 1.0 L per 1000 km (1.1 qt./600 miles,

0.9 Imp. qt./600 miles)

When judging the amount of oil consumption, keep in mind that the oil may have become diluted, making it difficult to judge the true level accurately.

For example, if a vehicle is used for repeated short trips and consumes a normal amount of oil, the dipstick may not show any drop in the oil level at all, even after 1000 km (600 miles) or more. This is because the oil is gradually becoming diluted with fuel or moisture, making it appear that the oil level has not changed.

The diluting ingredients evaporate out when the vehicle is then driven at high speeds, as on an expressway , making it appear that oil is excessively consumed after driving at high speeds.

NOTICE

Failure to check the oil level regularly could lead to serious engine trouble due to insufficient oil.

Importance of engine oil level check

One of the most important points in proper vehicle maintenance is to keep the engine oil at the optimum level so that oil function will not be impaired. Therefore, it is essential that the oil level be checked regularly. Lexus recommends that the oil level be checked every time you refuel the vehicle.

For detailed information on oil level check, see “Checking the engine oil level” on page 621.

620

USED ENGINE OIL

Page 92

ENGINE

CAUTION

 Used engine oil contains potentially harmful

contaminants which may cause skin disorders such as inflammation or skin cancer, so care should be taken to avoid prolonged and repeated contact with it. To remove used engine oil from your skin, wash thoroughly with soap and water.

 Do not leave used oil within the reach of children.  Dispose of used oil and used oil filters only in a safe

and acceptable manner. Do not dispose of used oil and used oil filters in household trash, in sewers or onto the ground. Call your Lexus dealer or a service station for information concerning recycling or disposal.

CHECKING THE ENGINE OIL LEVEL

With the engine at operating temperature and turned off, check the oil level on the dipstick.

1. To get a correct reading, the vehicle should be on level ground. After turning off the engine, wait a few minutes for the oil to drain back into the bottom of the engine.

2. Pull the dipstick out, hold a rag under the end and wipe it clean.

3. Reinsert the dipstick and push it in as far as it will go, or the reading will not be correct.

If the oil level is below or only slightly above the low mark, add engine oil of the same type as already in the engine.

ENGINE

Remove the oil filler cap and add engine oil a little at a time, checking the dipstick. We recommend that you use a funnel when adding oil. The approximate quantity of oil needed to raise the level between low mark and full mark on the dipstick is indicated as follows:

1.5 L (1.6 qt., 1.3 Imp. qt.) For the engine oil capacity , see “Specifications” on page 613. When the level reaches within the correct range, return the filler

cap and turn the cap clockwise until you hear a click.
