Maintenance and care
NOTICE
■When using a high pressure car wash
●Vehicles with rear view monitor sys-tem: When washing the vehicle, do not spray the camera or its sur-
rounding area directly with a high pressure washer. Shock applied from high pressure water may
cause the device to not operate normally.
●Do not spray water directly on the radar which is equipped behind the radar cover in the radiator grille.
Otherwise it may cause the device to be damaged.
●Do not bring the nozzle tip close to boots (rubber or resin manufac-tured cover), connectors or the fol-
lowing parts. The parts may be damaged if they come into contact with high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
●Keep the cleaning nozzle at least 30 cm (11.9 in.) away from the vehi-cles body. Otherwise resin section,
such as moldings and bumpers, may be deformed and damaged. Also, do not continuously hold the
nozzle in the same place.
●Do not spray the lower part of the
windshield continuously. If water enters the air conditioning system intake located near the lower part of
the windshield, the air conditioning system may not operate correctly.
●Do not wash the underside of the vehicle using a high pressure car washer.
■Cleaning the canvas top (if equipped)
●Remove bird droppings from the
fabric immediately, as their corro- sive effect an make the damage in the outer canvas fabric.
●Do not use organic substances (gasoline, kerosene, benzene or
strong solvents), which may be toxic or cause damage.
●Do not use harsh or abrasive clean-ers as they may damage the top material.
●Do not use water-repellents, wax or other preservative finishes as they
may stain the top material.
●Never use a high-pressure washer
to clean the canvas top. Increased high water pressure may force water past the sealing.
●Do not use automatic car wash machine. It is possible to damage
the outer canvas fabric.

WARNING
The engine compartment contains many mechanisms and fluids that
may move suddenly, become hot, or become electrically energized. To avoid death or serious 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. Oil and other fluids may also be hot.

6-3. Do-it-yourself maintenance
WARNING
●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 work-ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
●Take care because brake fluid can
harm your hands or eyes and dam- age painted surfaces. If fluid gets on your hands or in your eyes, flush
the affected area with clean 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 OFF. With the engine switch in ON, the
electric cooling fan may automatically start to run if the air conditioning is on and/or the coolant temperature is
high. ( P.261)
■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 fil-ter
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 refill-
ing, it may indicate a serious problem.

■Coolant selection
Only use “Toyota Super Long Life Cool-
ant” or a similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with
long-life hybrid organic 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 coolant, contact
any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■If the coolant level drops within a
short time of replenishing
Visually check the radiator, hoses,
engine coolant reservoir caps and water pump.If you cannot find a leak, have any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer, test the cap and check for leaks
in the cooling system.
Check the radiator, condenser clear
away any foreign objects. If either
of the above parts is extremely dirty
or you are not sure of their condi-
tion, have your vehicle inspected by
any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
WARNING
■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.
NOTICE
■When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mix-
ture of water and antifreeze must be used to provide proper lubrication, corrosion protection and cooling. Be
sure to read the antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or
paint.
Checking the radiator, con-
denser
WARNING
■When the engine is hot
Do not touch the radiator or con- denser as they may be hot and cause serious injuries, such as burns.

7-2. Steps to take in an emergency
When trouble arises
1Stop the vehicle in a safe place
and turn off the air conditioning
system, and then stop the
engine.
2 If you see steam: Carefully lift
the hood after the steam sub-
sides.
If you do not see steam: Care-
fully lift the hood.
3 After the engine has cooled
down sufficiently, inspect the
hoses and radiator core (radia-
tor) for any leaks.
Radiator
Cooling fan
If a large amount of coolant leaks,
immediately contact any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
4 The coolant level is satisfactory
if it is between the FULL or LOW
lines on the reservoir.
Reservoir
FULL line
LOW line
5 Add engine coolant if necessary.
Water can be used in an emergency if
If your vehicle overheats
The following may indicate that
your vehicle is overheating.
 The high engine coolant tem-
perature warning light
( P.304) comes on or flashes,
or a loss of engine power is
experienced. (For example,
the vehicle speed does not
increase.)
 “Engine Coolant Temp High
Stop in a Safe Place See
Owner’s Manual” is shown on
the multi-information display.
 Steam comes out from under
the hood.

7-2. Steps to take in an emergency
engine coolant is unavailable.
6 Start the engine and turn the air
conditioning system on to check
that the radiator cooling fan
operate and to check for coolant
leaks from the radiator or hoses.
The fan operate when the air condition-
ing system is turned on immediately after a cold start. Confirm that the fan is operating by checking the fan sound
and air flow. If it is difficult to check these, turn the air conditioning system on and off repeatedly. (The fan may not
operate in freezing temperatures.)
7 If the fan is not operating: Stop
the engine immediately and
contact any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
If the fan is operating: Have the
vehicle inspected at the nearest
any authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer.
WARNING
■When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
●If steam is seen coming from under the hood, do not open the hood until the steam has subsided. The
engine compartment may be very hot.
●Keep hands and clothing (espe-cially a tie, a scarf or a muffler) away from the fan and belts. Failure
to do so may cause the hands or clothing to be caught, resulting in serious injury.
●Do not loosen the coolant reservoir caps while the engine and radiator
are hot. High temperature steam or coolant could spray out.
NOTICE
■When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding
cool coolant to a hot engine too quickly can cause damage to the engine.
■To prevent damage to the cooling system
Observe the following precautions:
●Avoid contaminating the coolant
with foreign matter (such as sand or dust etc.).
●Do not use any coolant additive.
