DO-IT-YOURSELF SERVICE PRECAUTIONS  
If you perform maintenance by yourself, ensure to follow the correct procedures given  
in this section. You should be aware that incorrect or incomplete servicing may result in  
operating problems.  
This section gives instructions only for those items that are relatively easy for an owner to  
perform. There are still a number of items that must be done by a qualified technician with  
special tools, refer to “Maintenance requirements” on page 253.  
Utmost care should be taken when working on your vehicle to prevent accidental injury.  
CAUTION  
When working on the engine compartment  
The engine compartment contains many mechanisms and fluids hat may move  
suddenly, become hot, or become electrically energised. To avoid death or serious injury,  
observe the following precautions.  
•
When the engine is running, keep hands, clothing, and tools away from the moving  
fan and engine drive belts. (Removing rings, watches, and ties is advisable.)  
•
Immediately after driving, the engine compartment – the engine, radiator, exhaust  
manifold, power steering fluid reservoind spark plug boots, etc. – will be hot. So  
be careful not to touch them. Oil, flus and spark plugs may also be hot.  
•
•
•
•
•
If the engine is hot, do not removthe radiator cap or loosen the drain plugs to  
prevent burning yourself.  
Do not leave any combstle materials, such as paper or rags, in the engine  
compartment.  
Do not smoke, caue sparks or allow open flames around fuel or the battery. Their  
fumes are flammable.  
Be extremely cautious when working on the battery. It contains poisonous and  
corrosive sulphuric acid.  
Take care when filling the brake fluid reservoir because brake fluid can harm your  
hands or eyes. If fluid gets on your hands, flush the affected area with clean water  
immediately. If brake fluid gets in your eyes, flush your eyes with clean water  
immediately and seek medical assistance.  
When working near the electric cooling fans or radiator grille  
•
Vehicles with standard type ignition switch–  
Ensure the ignition switch is off if you work near the electric cooling fans or radiator  
grille. With the ignition switch on, the electric cooling fans will automatically start  
to run if the engine coolant temperature is high and/or the air conditioning is on.

ENGINE OIL  
Importance of engine oil level check  
One of the most important points in correct vehicle maintenance is to keep the engine oil  
at the optimum level so that oil function will not be impaired. Therefore, it is essential the  
oil level be checked regularly.  
Toyota recommends the oil level be checked every time you refuel the vehicle.  
NOTICE  
Failure to check the oil level regularly could lead to serious engine damage due to  
insufficient oil.  
Checking 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 parked on level ground.  
After turning off the engine, wait a few minutes for the oil to drain back into the  
engine sump.  
260  
MAINTENANCE AND CARE  
Do-it-yourself maintenance  
2. Pull the dipstick out while holding a  
rag under the end and wipe it clean.  
3. Reinsert the dipstick fully. The reading  
will be incorrect if it is not fully  
reinserted.  
Low  
Full  
4. Pull the dipstick out while holding a  
rag under the end and inspect the oil  
level.  
If the oil level is below or near the low  
level mark, add engine oil of the same  
type as already in the engine.  
CAUTION  
Be careful not to touch the hot exhaust manifold.  
Adding engine oil  
Remove the oil filler cap and add engine  
oil in small quantities 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 and full on the  
dipstick is 1.5 litres.  
When the level is within the correct range,  
install the filler cap hand-tight.  
For the engine oil capacity refer to “Lubrication” on page 329.  
NOTICE  
•
•
•
Be careful not to spill engine oil on the vehicle components.  
Avoid overfilling, or the engine could be damaged.  
Check the oil level on the dipstick once again after adding the oil.

CAUTION  
Used engine oil  
•
•
•
Used engine oil contains potentially harmful contaminants which may cause skin  
disorders such as inflammation and skin cancer, so care should be taken to avoid  
prolonged and repeated contact. To remove used engine oil from your skin, wash  
thoroughly with soap and water.  
Dispose of used oil and filters only in a safe and acceptable manner. Do not dispose  
of used oil and filters in household waste, in sewers or onto the ground. Call  
your Toyota dealer, service station or auto parts store for information concerning  
recycling or disposal.  
Do not leave used engine oil within the reach of children.  
Engine oil selection  
Toyota Genuine Motor Oil is used in your Toyota vehicle. Use Toyota approved Toyota  
Genuine Motor Oil or equivalent to satisfy the following grade and viscosity.  
Oil grade–  
•
5W-30 and 10W-30  
API grade SL Energy-Conserving, SM Energy-Conserving, SN Resource-Conserving or  
ILSAC multigrade engine oil  
•
15W-40 and 20W-50  
API grade SL, SM or SN multigrade egine oil  
Recommended viscosity (SAE)–  
If you use SAE 10W-30 or a higheviscosity  
engine oil in extremely low temperatures,  
the engine may become diffult to start, so  
SAE 5W-30 engine oil is rommended.  
Temperature range anticipated before  
next oil change.  
Oil viscosity explained (using 10W-30 as an example)–  
•
The 10W in 10W-30 indicates the characteristic of the oil which allows cold startability.  
Oils with a lower value before the W allow for easier starting of the engine in cold  
weather.  
•
The 30 in 10W-30 indicates the viscosity characteristic of the oil when the oil is at high  
temperature. An oil with a higher viscosity (one with a higher value) may be better  
suited if the vehicle is operated at high speeds, or under extreme load conditions.  
262  
MAINTENANCE AND CARE  
Do-it-yourself maintenance  
Oil identification marks  
Either or both API registered marks are added to some oil containers to help you select the  
oil you should use.  
1. The API Service Symbol is located anywhere on the outside of the container.  
–
The top portion of the label shows  
the oil quality designations by API  
(American Petroleum Institute)  
such as SN.  
–
–
The centre portion of the label  
shows the SAE viscosity grade  
such as SAE 10W-30.  
Resource-Conserving shown in the  
lower portion indicates the oil has  
fuel saving and environmental  
protection capabilities.  
2. The ILSAC (International Lubricant Standardisation and Approval Committee)  
Certification Mark is displayed on the front of thcontainer.  
To ensure excellent lubrication performance for your engine, Toyota Genuine Motor Oil is  
available which has been specifically tested and approved for all Toyota engines.  
Please contact your Toyota dealer for further tails about Toyota Genuine Motor Oil.  
Facts about engine oil consumption  
Functions of engine oil–  
Engine oil has the primary functins of lubricating and cooling the inside of the engine,  
and plays a major role in maintaining the engine in correct 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.  
The amount of engine oil consumed depends on the viscosity of the oil, the quality of the  
oil and the conditions the vehicle is driven under.  
More oil is consumed by high-speed driving and frequent acceleration and deceleration.  
263  
MAINTENANCE AND CARE  
Do-it-yourself maintenance  
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., 0.9 lmp. qt.)  
When judging the amount of oil consumption, note the oil may become diluted and make  
it difficult to judge the true level accurately.  
As an 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 or more. This is because the oil is gradually becoming diluted with fuel or moisture,  
making it appear 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.  
Importance of engine oil level check  
One of the most important points in correct vehicle maintenance is to keep the engine oil  
at the optimum level so that oil function will not be impaired. Therefore, it is essential the  
oil level be checked regularly. Toyota recommends the oil level be checked every time you  
refuel the vehicle.  
NOTICE  
Failure to check the oil level regularly could leao serious engine trouble due to  
insufficient oil.  
ENGINE COOLANT  
Checking engine coolant level  
Look at the see-through coolant reservoir when the engine is cold.  
1. Reservoir cap  
2. FULL line  
3. LOW line  
•
The coolant level is satisfactory if it is  
between the FULL and LOW lines on  
the reservoir when the engine is cold.  
•
The coolant level in the reservoir will  
vary with engine temperature.  
However, if the level is on or below the  
LOW line, add coolant. Bring the level  
up to the FULL line.  
•
If the coolant level drops within a short time after replenishing, there may be a leak in  
the system. Visually check the radiator, hoses, engine coolant filler cap, radiator cap  
and drain cock and water pump.  
If you can find no leak, have your Toyota dealer test the cap pressure and check for  
leaks in the cooling system.  
264  
MAINTENANCE AND CARE  
Do-it-yourself maintenance  
CAUTION  
When the engine is hot  
Do not remove the engine coolant reservoir cap. The cooling system may be under  
pressure and may spray hot coolant if the cap is removed, causing serious injuries, such  
as burns.  
Coolant type selection  
Use of incorrect coolants may damage your engine cooling system.  
Only use Toyota Super Long Life Coolant or similar high quality ethylene glycol based non-  
silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid  
technology. (Coolant with long-life hybrid organic acid technology is a combination of low  
phosphates and organic acids.)  
Toyota Super Long Life Coolant is a mixture of 50% coolant and 50deionised water. This  
coolant provides protection down to about –35˚C.  
Contact your Toyota dealer for further details.  
NOTICE  
•
•
Do not use plain water alone.  
Coolant is neither plain water nor straigt antifreeze. The correct mixture of water  
and antifreeze must be used to provie correct lubrication, corrosion protection and  
cooling.  
•
If you spill the coolant, wash it off with water immediately to prevent it from  
damaging parts or paint.  
RADIATOR AND CONDENSER  
Check the radiator and condenser and clear away any foreign objects such as leaves, etc.  
If the radiator or the condenser is extremely dirty or you are not sure of their condition,  
take your vehicle to a Toyota dealer.  
CAUTION  
To prevent burning yourself, be careful not to touch the radiator or condenser when the  
engine is hot.  
NOTICE  
To prevent damage to the radiator and condenser, do not perform the work by yourself.

MAINTENANCE AND CARE  
Do-it-yourself maintenance  
BRAKE FLUID  
Checking the brake fluid level  
To check the fluid level, simply look at the  
see-through reservoir. Refer to “Engine  
compartment overview” on page 260 for the  
location of the brake fluid reservoir. The  
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  
ensure to keep the reservoir filled.  
CTY43PAC001  
If the reservoir needs frequent refilling, it may indicate a serious mechanical problem.  
If the level is low, add SAE J1703 or FMVSS No. 116 DOT 3 brake fluid to the brake reservoir.  
Remove and replace the reservoir cover by hand. Fill the brake fluid the dotted line. This  
brings the fluid to the correct level when you put the cover 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.  
CAUTION  
Take care when filling the reservoir because brake fluid can harm your eyes and damage  
painted surfaces. If fluid gets in your eyes, flush our eyes with clean water, and seek  
medical assistance.  
NOTICE  
If fluid is spilt, wash it off with water immediately to prevent damage to parts or paint.  
WASHER FLUID  
If the windscreen washers do not operate, the windscreen washer fluid tank may be empty.  
Refer to “Engine compartment overview” on page 260 for tank location.  
Checking fluid level (without fluid gauge)  
Remove the washer fluid tank cap and visually check the fluid level. If washer fluid is not  
visible, add fluid until the washer fluid fills the tank neck.  
CTY43PAC010a  
266  
MAINTENANCE AND CARE  
Do-it-yourself maintenance  
Checking fluid level (with fluid gauge)  
1. Open the washer reservoir cap, pull out the fluid gauge and check the fluid level.  
2. Check the fluid level by observing the liquid-covered holes on the fluid gauge.  
If the level is below the second hole from the end of the gauge (the LOW mark) add  
washer fluid.  
Current  
fluid level  
CTY43AV089a  
CAUTION  
Do not add washer fluid when the engine is hot or rning as washer fluid contains  
alcohol and may catch fire if spilled on the enginetc.  
NOTICE  
Do not overfill  
Do not use any fluid other than washer fluid  
Do not use soapy water or egine antifreeze instead of washer fluid. Doing so may cause  
streaking or damage the vehicle’s painted surfaces.  
Diluting washer fluid  
Dilute washer fluid wth water as necessary. Refer to the freezing temperatures listed on  
the label of the washer fluid bottle.  
TYRES  
Checking tyre inflation pressure  
Keep your tyre inflation pressures at the  
correct level.  
The recommended cold tyre inflation  
pressures and tyre sizes is printed on the  
tyre placard located on the driver’s body  
pillar. Also refer to “Tyres and wheels” on  
page 332.  
You should check the tyre inflation  
pressure every two weeks, or at least once  
a month. And do not forget the spare!  
CTY61AV021a  
267  
MAINTENANCE AND CARE  
Do-it-yourself maintenance  
Incorrect tyre inflation pressure may waste fuel, reduce the comfort of driving, reduce tyre  
life and make your vehicle less safe to drive.  
The following instructions for checking tyre inflation pressure should be observed.  
•
The pressure should be checked only when the tyres are cold. If your vehicle has been  
parked for at least 3 hours and has not been driven for more than 1.5 km since, you  
will get an accurate cold tyre inflation pressure reading.  
•
•
•
Always use a tyre pressure gauge. The appearance of a tyre can be misleading. Tyres  
that are only slightly over or under inflated can degrade ride and handling.  
Do not bleed or reduce tyre inflation pressure after driving. It is normal for the tyre  
inflation pressure to be higher after driving.  
Reinstall the tyre 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.  
CAUTION  
•
Keep your tyres inflated in accordance with the vehicle’s specifications. Otherwise,  
death or serious injuries may result.  
•
Under inflation can result in:  
–
–
–
–
–
–
–
Possibility of blowouts from an overheated tyre  
Poor sealing of the tyre bead  
Wheel deformation and/or tyre saration  
Poor handling  
Increased possibility of tyre damage from road hazards  
Excessive wearing of tyres  
Uneven wearing of tyres.  
•
Over inflation of tyrcan result in:  
–
–
–
–
Poor handling  
Excessive wearing of tyres  
Uneven wearing of tyres  
Increased possibility of tyre damage from road hazards.  
268  
MAINTENANCE AND CARE  
Do-it-yourself maintenance  
NOTICE  
If tyre inflation pressure becomes low while driving  
Do not continue driving as your tyres and/or wheels may be ruined.  
Driving on rough roads  
Take particular care when driving on roads with loose surfaces or potholes.  
These conditions may cause losses in tyre inflation pressure, reducing the cushioning  
ability of the tyres. In addition, driving on rough roads may cause damage to the tyres  
themselves, as well as the vehicle’s wheels and body.  
Checking your tyres  
The tyres on your Toyota have built-in tread wear indicators to help you know when the  
tyres need replacement.  
The location of tread wear indicators is shown by the TWI or Δ ms, etc., moulded on the  
sidewall of each tyre as shown.  
1. New tread.  
2. Tread-wear indicator  
3. Worn tread  
When the tread depth wears to 1.6 mm or  
less, the indicators will appear. If you can  
see the indicators in two or more adjacent  
grooves, the tyre should be replaced.  
The lower the tread, the higher the risk of  
skidding.  
The effectiveness of snow tyres is lost if the  
tread wears down below mm.  
If you have tyre damage such as cuts, splits, cracks deep enough to expose the fabric, or  
bulges indicating internal damage, the tyre should be replaced.  
If a tyre often goes flat or cannot be correctly 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.  
If air loss occurs while driving, do not continue driving. Driving even a short distance can  
damage a tyre beyond repair.  
Tyres deteriorate with age even if they have never or seldom been used.  
Any tyres which are over 6 years old must be checked by a qualified technician even if  
damage is not obvious. This applies also to the spare tyre and tyres stored for future use.  
269  
MAINTENANCE AND CARE  
Do-it-yourself maintenance  
Replacing your tyres  
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 tyres on your vehicle, as this may cause  
dangerous handling characteristics resulting in loss of control.  
Do not use tyres other than the manufacturer’s recommended size, as this may  
cause dangerous handling characteristics resulting in loss of control.  
Do not mix tyres of different makes, models or tread patterns, and do not mix  
tyres of remarkably different tread wear. This may cause dangerous handling  
characteristics resulting in loss of control.  
When replacing a tyre, use a tyre of the same size and construction, and the same or  
greater load capacity as the originally installed tyres.  
Using any other size or type of tyre may seriously affect handling, ride,  
speedometer / odometer calibration, ground clearance, and clearance between the body  
and tyres or snow chains.  
Never use second-hand tyres on your Toyota. Using tys whose previous history is  
unknown is a risk.  
Toyota recommends all four tyres, or at least both ront or rear tyres be replaced at a time  
as a set.  
Refer to “If you have a flat tyre” on page 306 for tyre change procedure.  
When a tyre is replaced, the wheel sould always be balanced.  
An unbalanced wheel may affect vehicle handling and tyre life. Wheels can get out of  
balance with regular use and should therefore be balanced occasionally.  
When replacing a tubelestyre, the air valve should also be replaced with a new one.  
Rotating tyres  
To equalise tyre wear and help extend tyre life, Toyota recommends that you rotate your  
tyres approximately every 10000 km. However, the most appropriate timing for tyre rotation  
may vary according to your driving habits and road surface conditions.  
Refer to “If you have a flat tyre” on page 306  
for tyre change procedure.  
When rotating tyres, check for uneven wear  
and damage. Abnormal wear is usually  
caused by incorrect tyre pressure, incorrect  
wheel alignment, out-of-balance wheels or  
severe braking.  
Front  
•
Rotate the tyres in the order shown.

MAINTENANCE AND CARE  
Do-it-yourself maintenance  
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 tyre may slip off the wheel or cause loss of  
handling control.  
Refer to “If you have a flat tyre” on page 306 for tyre change procedure.  
Wheel selection  
When replacing wheels, care should be taken to ensure the wheels are replaced by ones  
with the same load capacity, 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, whel and bearing life,  
brake cooling, speedometer / odometer calibration, stopping abilheadlight aim, bumper  
height, vehicle ground clearance, and tyre or snow chain clearance to the body and  
chassis.  
Replacement with used wheels is not recommended as they may have been subjected to  
rough treatment or high mileage and could fail withowarning. Also, bent wheels which  
have been straightened may have structural damae and therefore should not be used.  
Never use an inner tube in a leaking wheel which is designed for a tubeless tyre.  
CAUTION  
Do not use wheels other than the manufacturer’s recommended size, as this may cause  
dangerous handling characteristics resulting in loss of control. Otherwise, an accident  
may occur resulting in death or serious injuries.  
Aluminium wheel precautions  
•
When installing uminium wheels, check the wheel nuts are tight after driving your  
vehicle the first 1600 km.  
•
If you have rotated, repaired, or changed your tyres, check the wheel nuts are still  
tight after driving 1600 km.  
•
•
•
When using tyre chains, be careful not to damage the aluminium wheels.  
Use only Toyota wheel nuts and wrench designed for your aluminium wheels.  
When balancing your wheels, use only Toyota balance weights or equivalent and a  
plastic or rubber hammer.  
•
As with any wheel, periodically check your aluminium wheels for damage. If damaged,  
replace immediately.

fuse of the same amperage rating.  
277  
MAINTENANCE AND CARE  
Do-it-yourself maintenance  
Type B–  
1. Normal fuse.  
2. Blown fuse.  
•
Remove the fuse by pulling it straight  
out and check if it has blown.  
•
Replace the blown fuse with a new  
fuse of the same amperage rating.  
Type C–  
1. Normal fuse.  
2. Blown fuse.  
•
Contact your Toyota dealer.  
If you cannot use a fuse of the same amperage, use one that is lower, but as close to  
the rating as possible. If the amperage is lwer than that specified, the fuse might blow  
out again but this does not indicate anything wrong. Obtain 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 vehicle for  
emergencies.  
If the new fuse immediately ows out, there is a problem with the electrical system. Have  
your Toyota dealer corrct it as soon as possible.  
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.

LIGHT BULBS  
Light bulb locations  
You may replace the light bulbs shown in the following illustrations. The difficulty level of  
replacement varies depending on the bulb. As there is a danger that components may be  
damaged, we recommend that replacement is carried out by your Toyota dealer.  
Vehicles with standard type ignition switch–  
When replacing a bulb, make sure the ignition switch and light switch are off.  
Vehicles with smart entry and start system–  
When replacing a bulb, make sure the ENGINE START STOP switch and light switch are off.  
CAUTION  
Discharge headlights  
•
•
Contact your Toyota dealer before replacing discharge headlights and/or bulbs.  
Do not touch the discharge headlight’s high voltage socket when the headlights are  
turned on.  
•
•
An extremely high voltage of 30000 V will be discharged and could result in serious  
injury or death by electric shock.  
Do not attempt to take apart or repair the low beam discharge headlight bulbs,  
connectors, power supply circuits, or related components. Doing so could result in  
electric shock and serious injury or death.  
•
While the low beam headlights  
are turned on, and for a short time  
after they have been turned off,  
metal components at the rear
the headlight assembly will be  
extremely hot. To prevent burns, do  
not touch these metal omponents  
until you are certn they have  
cooled down.  
CAUTION  
•
•
To prevent burning yourself, do not replace the light bulbs while they are hot.  
Halogen bulbs have pressurised 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.  
•
Fully install light bulbs and any parts used to secure them. Failure to do so may  
result in heat damage, fire, or water entering the headlight unit. This may damage  
the headlights or cause condensation to build up on the lens.  
284  
MAINTENANCE AND CARE  
Do-it-yourself maintenance  
NOTICE  
•
Only use a bulb of the listed type and wattage.  
Discharge headlights  
•
If voltage to the discharge bulbs is insufficient, the bulbs may not come on, or  
may go out temporarily. The discharge bulbs will come on when normal power is  
restored.  
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 windscreen fogs up in the rain. However, if there is a large amount of water on the  
inside of the lens, or if there is water pooled inside the light, contact your Toyota dealer.
