request that a record of maintenance
be kept.
QDoes your vehicle need repairs?
Be on the alert for changes in perfor-
mance and sounds, and visual tip-offs
that indicate service is needed. Some
important clues are:
OEngine missing, stumbling or pinging
OAppreciable loss of power
OStrange engine noises
OA fluid leak under the vehicle (How-
ever, water dripping from the air con-
ditioning system after use is normal.)
OChange in exhaust sound (This may
indicate a dangerous carbon monox-
ide leak. Drive with the windows open
and have the exhaust system checked
immediately.)
OFlat-looking tires, excessive tire
squeal when cornering, uneven tire
wear
OVehicle pulls to one side when driven
straight on a level road
OStrange noises related to suspension
movement
OLoss of brake effectiveness, spongy
feeling brake pedal, pedal almost
touches the floor, vehicle pulls to one
side when braking
OEngine coolant temperature continu-
ally higher than normal (P.551)
If you notice any of these clues, take
your vehicle to any authorized Toyota
retailer or Toyota authorized repairer, or
any reliable repairer as soon as possi-
ble.
Your vehicle may need adjustment or
repair.

Maintenance and care
WARNING
QWhen working on the engine compartment
OMake sure that “IGNITION ON” on the multi-information display and the “READY” indicator are both off.
OKeep hands, clothing and tools away from the moving fan.
OBe careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other flu-ids may also be hot.
ODo not leave anything that may burn easily, such as paper and
rags, in the engine compartment.
ODo not smoke, cause sparks or
expose an open flame to fuel. Fuel fumes are flammable.
OTake 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.
QWhen working near the electric
cooling fan or radiator grille
Be sure the power switch is off. With the power 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.458)
QSafety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc., from getting in your eyes.
NOTICE
QIf 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.
QIf 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.

WARNING
QPre-driving check
Check that the hood is fully closed
and locked. If the hood is not locked properly, it
may open while the vehicle is in motion and cause an accident, which may result in death or serious injury.
QTo prevent burns
Do not touch the pipes when the com-
pressor is operating or after it is stopped, because the pipes are hot.
Touching by hands before the pipes
cool down may cause burns.
QAfter installing the support rod
into the slot
Make sure the rod supports the hood securely from falling down on to your
head or body.

ground. After warming up the
engine and turning off the hybrid
system, wait more than 5 min-
utes for the oil to drain back into
the bottom of the engine.

QChecking the oil type and pre-
paring the items needed
Make sure to check the oil type and
prepare the items needed before
adding oil.

Maintenance and care
QEngine oil consumption
A certain amount of engine oil will be
consumed while driving. In the following situations, oil consumption may increase, and engine oil may need to be
refilled in between oil maintenance inter- vals.
OWhen the engine is new, for example directly after purchasing the vehicle or after replacing the engine
OIf low quality oil or oil of an inappropri-ate viscosity is used
OWhen driving at high engine speeds or with a heavy load, when towing, or
when driving while accelerating or decelerating frequently
OWhen leaving the engine idling for a long time, or when driving frequently through heavy traffic
The coolant level is satisfactory if it
is between the “FULL” and “LOW”
lines on the reservoir when the
hybrid system is cold.

WARNING
QUsed engine oil
OUsed engine oil contains poten-
tially harmful contaminants which may cause skin disorders such as inflammation and skin cancer, so
care should be taken to avoid pro- longed and repeated contact. To remove used engine oil from your
skin, wash thoroughly with soap and water.
ODispose of used oil and filters only in a safe and acceptable manner. Do not dispose of used oil and fil-
ters in household trash, in sewers or onto the ground. Call any autho-rized Toyota retailer or Toyota
authorized repairer, or any reliable repairer, service station or auto parts store for information concern-
ing recycling or disposal.
ODo not leave used engine oil within
the reach of children.
NOTICE
QTo prevent serious engine dam- age
Check the oil level on a regular basis.
QWhen replacing the engine oil
OBe careful not to spill engine oil on the vehicle components.
OAvoid overfilling, or the engine could be damaged.
OCheck the oil level on the dipstick every time you refill the vehicle.
OBe sure the engine oil filler cap is properly tightened.
QIf oil is spilled on the engine cover
To prevent the engine cover from
being damaged, remove any engine oil from the engine cover as soon as possible using a neutral detergent. Do
not use an organic solvent such as brake cleaner.

QCoolant selection
Only use “Toyota Super Long Life Coo- lant” 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.
QIf the coolant level drops within a short time of replenishing
Visually check the radiators, hoses,
engine/power control unit coolant reser- voir caps, drain cock 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 and condenser,
and clear away any foreign objects.
If either of the above parts is
extremely dirty or you are not sure
of their condition, have your vehicle
inspected by any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.

WARNING
QWhen the hybrid system is hot
Do not remove the engine/power con- trol unit coolant reservoir caps.
The cooling system may be under pressure and may spray hot coolant if the cap is removed, causing serious
injuries, such as burns.
NOTICE
QWhen 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.
QIf you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or
paint.
