WARNING
■To prevent the windshield from fogging up
● Do not use during cool air operation in extremely humid weather. The
difference between the temperature of the outside air and that of the wind-
shield can cause the outer surface of the windshield to fog up, blocking
your vision.
■ To prevent burns
● Vehicles with outside rear view mirror defoggers: Do not touch the rear
view mirror surfaces when the outsi de rear view mirror defoggers are on.
● Vehicles with windshield wiper de-icer: Do not touch the glass at lower part
of the windshield or the side of the front pillars when the windshield wiper
de-icer is on.
NOTICE
■ To prevent battery discharge
Do not leave the air conditioning syst em on longer than necessary when the
engine is not running.
● Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.

*: The shape of the auxiliary box may differ depending on the grade, etc.
●Air conditioning-linked temperature regulation function (type A) (if
equipped):
By introducing air from the air conditioning system into the auxiliary box,
canned drinks etc. can be kept hot or cold. However, as the temperature
inside the auxiliary box will become the same as the temperature of the air
flowing from the air conditioning sy stem, extreme heating and cooling are
not possible. In high humidity condition, be careful of objects inside the aux-
iliary box, as condensation may form.
● Using the air conditioning-linked temperature regulation function (type A) (if
equipped):
Allow the air conditioning system to operate, and use or to
select either or . ( P. 484, 493)
Adjust the temperature. ( P. 484, 492)
Type G (if equipped)
Open the air intake lid inside the aux-
iliary box.
To blow a large amount of air into the
auxiliary box, close the passenger
side vent. ( P. 487, 496)

Maintenance and care
■Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Toyota recom-
mends that maintenance service operations as well as other inspections and
repairs be carried out by authorized Toyota retailers or Toyota authorized
repairers, or any reliable repairers. For repairs and services covered by your
warranty, please visit an authorized Toyota retailer or repairer, who will use
genuine Toyota parts in repairing any difficulties you may encounter. There
can also be advantages in utilizing authorized Toyota retailers or repairers for
non-warranty repairs and services, as members of the Toyota network will be
able to expertly assist you with any difficulties you may encounter.
Your Toyota retailer or Toyota authoriz ed repairer, or any reliable repairer will
perform all of the scheduled maintenance on your vehicle reliably and eco-
nomically due to their experience with Toyota vehicles.
■ 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 missing, 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 indicate a dangerous carbon monoxide
leak. Drive with the windows open and have the 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,
pedal 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 your vehicle to any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as soon as pos-
sible. Your vehicle may need adjustment or repair.

Maintenance and care
Check the radiator, condenser and intercooler and clear away any for-
eign objects. If any 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
■ When the engine is hot
Do not remove the radiator cap or 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 mixture 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.
■ Notice on coolant quality
Do not use improper coolant. If improper coolant is used, the engine cooling
system may be damaged.
Radiator, condenser and intercooler (if equipped)
WARNING
■ When the engine is hot
Do not touch the radiator, condenser or intercooler as they may be hot and
cause serious injuries, such as burns.

Maintenance and care
AdBlue™ is used to reduce the amount of nitrogen oxides in exhaust
gas. AdBlue™ is consumed in the process of driving. Therefore,
observe the following precautions.
● 1.0 L (1.1 qt., 0.9 Imp.qt.) of AdBlue™ is consumed every 1500 km
(932 miles). Normally, after a full refill, the vehicle can be driven for
approximately 15000 km (9321 miles) before all AdBlue™ is
depleted.
However, AdBlue™ may become completely depleted sooner
depending on driving conditions.
● When the possible driving range based on the remaining amount of
AdBlue™ reaches approximately 2400 km (1492 miles), the low
AdBlue™ level warning light turns on and a warning message is
displayed.
● When AdBlue™ is depleted, the engine cannot be restarted.
● If AdBlue™ is accidentally spilled while refilling, vehicle parts, paint,
etc. may be damaged.
When AdBlue™ needs to be refilled, have it refilled at any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
It may be a criminal offence to use a vehicle that does not consume
any reagent if it is required for the reduction of emissions.
■AdBlue™ warning light and warning message
When the AdBlue™ level is low,
the low AdBlue™ level warning
light turns on and a warning
message appears on the multi-
information display. ( P. 554)
When refilling AdBlue™ by
yourself in an emergency, be
sure to follow the correct refill-
ing procedures. ( P. 555)
