Do-it-yourself maintenance
⚫What about do-it-yourself maintenance?
Many of the maintenance items are easy to do yourself if you have a little mechanical
ability and a few basic automotive tools. Simple instructions for how to perform them
are presented in this section.
Note, however, that some maintenance task s require special tools and skills. These
are best performed by qualified technician s. Even if you are an experienced do-it-
yourself mechanic, we recommend that repairs and maintenance be conducted by
your Toyota dealer who will keep a record of maintenance on your vehicle. This
record could be helpful should you ever require Warranty Service.
⬛Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs that
indicate service is needed. Some important clues are:
⚫Engine misses, stumbling or pinging
⚫Appreciable loss of power
⚫Strange engine noises
⚫A fluid leak under the vehicle (However , water dripping from the air condi-
tioning system after use is normal.)
⚫Change in exhaust sound (This may indica te a dangerous carbon monoxide leak.
Drive with the windows open and have th e exhaust system checked immediately.)
⚫Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
⚫Vehicle pulls to one side when driven straight on a level road
⚫Strange noises related to suspension movement
⚫Loss of brake effectiveness, spongy feeling brake pedal or clutch pedal (vehi-
cles with a manual transmission), pe dal almost touches the floor, vehicle
pulls to one side when braking
⚫Engine coolant temperature continually higher than normal
If you notice any of these clues, take yo ur vehicle to your Toyota dealer as soon
as possible. Your vehicle may need adjustment or repair.

WARNING
The engine compartment contains many mechanisms and fluids that may move
suddenly, become hot, or become electrically energized. To avoid death or seri-
ous injury, observe the following precautions.
⬛When working on the engine compartment
⚫Keep hands, clothing and tools away from the moving fan and engine drive
belt.
⚫Be careful not to touch the engine, radiator, exhaust manifold, etc., right
after driving as they may be hot. O il and other fluids may also be hot.
⚫Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
⚫Do not smoke, cause sparks or expose an open flame to fuel or the battery.
Fuel and battery fumes are flammable.
⚫Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
⚫Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with cl ean water immediately.
If you still experience discomfort, consult a doctor.
⬛When working near the electric cooling fan or radiator grille
Be sure the engine switch is in off.
With the engine switch in “ON”, the elect ric cooling fan may automatically start
to run if the air conditioning is on and/or the coolant temperature is high.
( ➞ P. 320)
⬛Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in your eyes.
NOTICE
⬛If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.
⬛If the fluid level is low or high
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 problem.

RAIZE_OM_General_BZ358E
⚫When the outside temperature is low, the engine oil may become white and
creamy, and it may get to the back of the oil filler cap or oil filling port.This
phenomenon takes place when water vapor in the engine is cooled, forming
water drops, which in turn are mixed wi th the engine oil. This, however, will
disappear when the water evaporates as the outside temperature gets high
or the engine warms up.The engine oil does not deteriorate due to this phe-
nomenon and there will be no problem if the engine oil is continued to be
used.
WARNING
⬛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 hous ehold trash, in sewers or onto the
ground.
Call your Toyota dealer, service stat ion or auto parts store for information
concerning recycling or disposal.
⚫Do not leave used engine oil within the reach of children.
⬛If engine oil is spilled
If oil is spilled on the alternator, wipe off the oil immediately. Oil spilled on the
alternator will cause a fire.
NOTICE
⬛To prevent serious engine damage
Observe the following precautions.
⚫Check the oil level on a regular basis.
⚫Do not use any engine oil additive.
⬛When replacing the engine oil
⚫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 every time you refill the vehicle.
⚫Be sure the engine oil filler cap is properly tightened.

Engine coolant
The coolant level is satisfactory if it is between the “FULL” and “LOW” lines
on the reservoir when the engine is cold.
a Reservoir cap
b “FULL” line
c “LOW” line
If the level is on or below the “LOW”
line, add coolant up to the “FULL” line.
(➞ P. 412)
⬛Coolant selection
Only use “Toyota Super Long Life Coolan t” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with
long-life hybrid org anic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature: -35°C [-31°F])
For more details about engine coolant, contact your Toyota Genuine dealer.
⬛If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir cap, drain cock and
water pump.
If you cannot find a leak, have your Toyo ta dealer test the cap and check for
leaks in the cooling system.
WARNING
⬛When the engine is hot
Do not remove the radiator cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing seri ous injuries, such as burns.
⬛When replacing the coolant
To avoid coolant spilling on the altern ator, do not remove the upper radiator
hose from engine side (remove from the radiator side). Coolant spilled on the
alternator will cause corrosion of the coil and a fire.
