tip−offs
for changes
Does your vehicle need repairing? Be on the alert in perfor- mance, sounds, and visual that indicate service is needed. Some impor- tant clues are as follows: D Engine missing, stumbling, or pinging D Appreciable loss of power D Strange engine noises D A leak under the vehicle (however, wa- ter dripping from the air conditioning after use is normal.)
D Change
in exhaust sound (This may indicate a dangerous carbon monoxide leak. Drive with the windows open and have the exhaust system checked im- mediately.)
D Flat−looking tire; excessive tire squeal
when cornering; uneven tire wear
D Vehicle pulls to one side when driving
straight on a level road
D Strange noises related to suspension
movement
D Loss of brake effectiveness; spongy feeling brake pedal; pedal almost touches floor; vehicle pulls to one side when braking
D Engine coolant temperature continually
higher than normal
If you notice any of these clues, take your vehicle to your Toyota dealer as soon as possible. It probably needs adjustment or repair.
CAUTION
Do not continue driving with the ve- hicle unchecked. It could result in se- rious vehicle damage and possibly personal injury.

Do−it−yourself service precautions If you perform maintenance by yourself, be sure to follow the correct procedure given in this Section. You should be aware that improper or in- complete servicing may result in operating problems. Performing do−it−yourself maintenance during the warranty period may affect your warranty coverage. Read the separate Toyota Warranty statement for details and suggestions. This Section gives for those items that are relatively easy for an owner to perform. As explained in Section 6, there are still a number of items that must be done by a qualified technician with special tools. For information on tools and parts for do− it−yourself maintenance, see “Parts and tools” on page 377 in this Section. Utmost care should be taken when work- ing on your vehicle to prevent accidental injury. Here are a few precautions that you should be especially careful to ob- serve:

D Do not smoke, cause sparks or al- low open flames around fuel or the battery. Their fumes are flammable. D Do not get under your vehicle with just the body jack supporting it. Al- ways use automotive jack stands or other solid supports.
D Be sure that the ignition is off if you work near the electric cooling fans or radiator grille. With the ignition on, the electric cooling fans will automatically start to run if the engine coolant temperature is high and/or the air conditioning is on.
D Use eye protection whenever you work on or under your vehicle where you may be exposed to flying or falling material, fluid spray, etc. D Used engine oil contains potentially harmful contaminants which may cause skin disorders such as in- flammation or skin cancer, so care should be taken to avoid prolonged and repeated contact with it. To re- move used engine oil from your skin, wash thoroughly with soap and water.
D Do not
leave used oil within the
reach of children.
D Dispose of used oil and filter only in a safe and acceptable manner. Do not dispose of used oil and fil- ter in household trash, in sewers or onto the ground. Call your dealer or a service station information concerning recycling or disposal.

Checking brake fluid
Checking power steering fluid
Remove and replace the reservoir cap by hand. Fill the brake fluid to the dotted line. This brings the fluid to the correct level when you put the cap back on. 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.

If you spill some of the fluid, be sure to wipe it off to prevent it from dam- aging the parts or paintwork.
reservoir. The
To check the fluid level, simply look at the see−through level should be between the “MAX” and “MIN” lines on the reservoir. 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 prob- lem. If the level is low, add SAE J1703 or FMVSS No.116 DOT 3 brake fluid to the brake reservoir.
384
Check the fluid level through the reser-
voir. If necessary, add automatic trans-
mission fluid DEXRONrII or III.
If the vehicle has been driven around 80

Checking tire inflation pressure
Keep your tire inflation pressures at the proper level. The recommended cold tire inflation pressures, tire sizes and the com- bined weight of occupants and cargo (vehicle capacity weight) are de- scribed on page 404 and 408. They are also on the tire and loading infor- mation label. You should check the tire inflation pressure every two weeks, or at least once a month. And do not forget the spare!

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 pres-
sure reading.
D 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 ride and handling.
D Do not bleed or reduce tire inflation pressure after driving. It is normal for the tire inflation pressure to be higher after driving. D Never exceed the vehicle capac- ity weight. Passenger and lug- gage weight should be located so that the vehicle is balanced.
INSPECTION AND ADJUSTMENT PROCEDURE 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 grad-
uations 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.
386
5. After completing the tire inflation pressure measurement and ad- justment, apply soapy water to the valve and check for leakage.
6. Install the tire valve cap. If a gauge and air pump are not avail- able, have your vehicle checked by your Toyota 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 pos- sible.
Incorrect tire inflation pressure may waste fuel, reduce the comfort of driv- ing, reduce tire life and make your ve- hicle less safe to drive. If a tire frequently needs refilling, have it checked by your Toyota deal- er.
CAUTION
Keep your tires properly inflated. Otherwise, the following condi- tions may occur and cause an ac- cident resulting in death or seri- ous injuries. Low tire pressure (underinfla- tion)— D Excessive wear D Uneven wear D Poor handling D Possibility of blowouts from an
overheated tire
D Poor sealing of the tire bead D Wheel deformation and/or tire
separation
D A greater possibility of tire
damage from road hazards

CHECKING YOUR TIRES Check the tire’s tread for tread wear indicators. If the indicators show, replace the tires. The loca- tion of tread wear indicators is shown by the “TWI” or “Δ” marks, etc., molded on the sidewall of each tire.
387
’06 HIGHLANDER_U (L/O 0508)
The tires on your Toyota have built−in tread wear indicators to help you know when the tires need replace- ment. When the tread depth wears to 1.6 mm (0.06 in.) or less, the indica- tors will appear. If you can see the indicators in two or more adjacent grooves, the tire should be replaced. The lower the tread, the higher the risk of skidding. 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 indi- cating 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 Toyota dealer.
388
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 applies also to the spare tire and tires stored for future use.
REPLACING YOUR TIRES 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 be- tween 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 Cer- tification Label.
For details about the side wall of the tire and the Certification Label, see pages 301 and 304.
CAUTION
Observe the following instruc- tions. Otherwise, an accident may occur resulting in death or serious injuries. D Do not mix radial, bias belted, or bias−ply tires on your ve- hicle, as this may cause dan- gerous handling characteris- tics resulting in loss of control. D Do not use tires other than the manufacturer’s recommended size, as this may cause danger- ous handling characteristics resulting in loss of control.
’06 HIGHLANDER_U (L/O 0508)
Rotating tires
D Four−wheel drive models:
Do not use tires of different brands, sizes, construction or tread patterns, as this may cause dangerous handling characteristics in loss of control.
resulting
Toyota recommends all four tires, or at least both of the front or rear tires be replaced at a time as a set. See “If you have a flat tire” on page 337 in Section 4 for tire change proce- dure. When a tire is replaced, the wheel should always be balanced. An unbalanced wheel may affect ve- hicle handling and tire life. Wheels can get out of balance with regular use and should therefore be balanced occasionally. When replacing a tubeless tire, the air valve should also be replaced with a new one.
To equalize tire wear and help ex- tend tire life, Toyota recommends that you rotate your tires accord- ing to the maintenance schedule. (For scheduled maintenance infor- mation, please refer to the “Sched- uled Maintenance Guide” or “Own- er’s Supplement”.) However, the most appropriate tim- ing for tire rotation may vary ac- cording to your driving habits and road surface conditions. See “If you have a flat tire” on page 337 in Section 4 for tire change proce- dure.
Manual
389
’06 HIGHLANDER_U (L/O 0508)
When rotating tires, check for uneven wear and damage. Abnormal wear is usually caused by incorrect tire pres- sure, improper wheel alignment, out− of−balance wheels, or severe braking. Initial adjustment of the tire pres- sure warning system is necessary after you have rotated your tires. See “Tire pressure warning sys- tem” on page 159 in Section 1−7.
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 tires provide better traction than snow 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 those men- tioned above. Do not install studded tires without first checking local regulations for possible restrictions.
CAUTION
the
following
Observe instructions. Otherwise, an accident may occur re- sulting in death or serious injuries. D Do not use snow tires other than the manufacturer’s recommended si- ze, as this may cause dangerous handling characteristics resulting in loss of control.
390
D Four−wheel drive models:
Do not use snow tires of different brands, sizes, construction or tread patterns, as this may cause danger- ous handling characteristics result- ing in loss of control.
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. When storing removed tires, you should store them in a cool dry place. Mark the direction of rotation and be sure to install them in the same direction when replacing.
CAUTION
D Do not drive with the snow tires
incorrectly inflated.
D Never drive over 120 km/h (75 mph)
with any type of snow tires.

CHAIN INSTALLATION Install the chains on the front tires as tightly as possible. Do not use tire tires. Retighten chains on chains after km (1/4—1/2 mile). When installing chains on your tires, care- fully follow the instructions of the chain manufacturer. If wheel covers are used, they will be scratched by the chain band, so remove the covers before putting on the chains.

D Use only Toyota wheel nuts and for your aluminum
wrench designed wheels.
D When balancing your wheels, use only Toyota balance weights or equivalent and a plastic or rubber hammer.
D As with any wheel, periodically check your aluminum wheels for damage. If damaged, replace immediately.
Replacement with used wheels is not rec- ommended as they may have been sub- jected to rough treatment or high mileage and could fail without warning. Also, bent wheels which have been straightened may have structural damage and therefore should not be used. Never use an inner tube in a leaking wheel which is designed for a tubeless tire.

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. WHEEL SELECTION When replacing wheels, care should be taken to ensure that the wheels are re- placed by ones with the same load ca- pacity, diameter, rim width, and offset. Correct replacement wheels are available at your Toyota dealer. A wheel of a different size or type may adversely affect handling, wheel and bear- ing life, brake cooling, speedometer/odom- eter calibration, stopping ability, headlight aim, bumper height, vehicle ground clear- ance, and tire or snow chain clearance to the body and chassis.

If the headlights or other electrical components do not work, check the fuses. If any of the fuses are blown, they must be replaced. See “Fuse locations” on page 374 in Sec- tion 7−1 for locations of the fuses. Turn the ignition switch and inoperative component off. Pull the suspected fuse straight out and check it. Determine which fuse may be causing the problem. The lid of the fuse box shows the name of the circuit for each fuse. See page 409 in Section 8 for the functions controlled by each circuit.
Type A fuses can be pulled out by using the pull−out tool. The location of the pull− out tool is shown in the illustration. If you are not sure whether the fuse has blown, try replacing the suspected fuse with one that you know is good. If the fuse has blown, push a new fuse into the clip. Only install a fuse with the amperage rat- ing designated on the fuse box lid. If you do not have a spare fuse, in an emergency you can pull out the “FR DEF” or “CIG” fuse, which may be dispensable for normal driving, and use it if its amper- age rating is the same. If you cannot use one of the same amper- age, use one that is lower, but as close to the rating as possible. If the amperage is 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 clip. It is a good idea to purchase a set of spare fuses and keep them in your ve- hicle for emergencies.

If fuse immediately blows out, there is a problem with the electrical sys- tem. Have your Toyota dealer correct it as soon as possible.
CAUTION
Never use a fuse with a higher am- perage rating, or any other object, in place of a fuse. This may cause ex- tensive damage and possibly a fire.
Adding washer fluid If any washer does not work or the low windshield washer fluid level warning light comes on, the washer tank may be empty. Add washer fluid. You may use plain water as washer fluid. However, in cold areas where tempera- tures range below the freezing point, use washer fluid containing antifreeze. This product is available at your Toyota dealer and most auto parts stores. Follow the manufacturer’s directions for how much to mix with water.
