NOTICE
QWhen using a high pressure car wash
O Vehicles with Toyota Safety Sense:
Do not spray water directly on the radar which is equipped behind the
emblem. Otherwise it may cause the device to be damaged.
O Do not bring the nozzle tip close to boots (rubber or resin manufactured
cover), connectors or the following parts. The parts may be damaged if
they come into contact with high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
O Keep the cleaning nozzle at least 30 cm (11.9 in.) away from the vehicle
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.
O 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 cor-
rectly.
O Do not wash the underside of the vehicle using a high pressure car
washer.

QWhere 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.
Q 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:
O Engine missing, stumbling or pinging
O Appreciable loss of power
O Strange engine noises
O A fluid leak under the vehicle (However, water dripping from the air condi-
tioning system after use is normal.)
O Change in exhaust sound (This may indicate a dangerous carbon monoxide
leak. Drive with the windows open and have the exhaust system checked
immediately.)
O Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
O Vehicle pulls to one side when driven straight on a level road
O Strange noises related to suspension movement
O Loss of brake effectiveness, spongy feeling brake pedal or clutch pedal,
pedal almost touches the floor, vehicle pulls to one side when braking
O 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
QIf the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir cap, intercooler
coolant reservoir cap (if equipped), 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, condenser and intercooler coolant radiator/inter-
cooler and clear away any foreign objects. If any of the above parts is
extremely dirty or you are not sure of their condition, have your vehi-
cle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
WARNING
Q When the engine is hot
Do not remove the radiator cap (if equipped), the engine coolant reservoir
cap or intercooler coolant reservoir cap (if equipped).
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
NOTICE
Q 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.
Q If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.
Q 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 coolant radiator/intercooler

WARNING
Q When the engine is hot
Do not touch the radiator, condenser or intercooler coolant radiator/inter-
cooler as they may be hot and cause serious injuries, such as burns.

AdBlue™ is used to reduce the amount of nitrogen oxides in exhaust
gas. Make sure to observe the following precautions regarding
AdBlue™.
O AdBlue™ is consumed in the process of driving.
O When AdBlue™ is depleted, the engine cannot be restarted.
O When AdBlue™ needs to be refilled, have it refilled at any autho-
rized 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.
QPossible driving range
The amount of AdBlue™ that is consumed while driving differs
according to the driving conditions and driving environment. When
the amount of AdBlue™ that is consumed increases, the possible
driving range until it is necessary to refill AdBlue™ decreases.
*1: When the vehicle is used at high elevations and in low temperatures, the
amount of AdBlue™ that is consumed increases.
*2: During normal driving, 1.0 L (1.1 qt., 0.9 Imp.qt.) of AdBlue™ is con-
sumed approximately every 600 km (373 miles). Also, after a full refill, the
vehicle can be driven for approximately 10000 km (6214 miles) before all
AdBlue™ is depleted.

QWarning message
If the following warning message is displayed on the multi-information dis-
play, follow the appropriate troubleshooting procedure.
*1: Use the driving range as a reference. The possible driving range that is dis-
played may differ from the actual driving range depending on the refill
method, driving conditions and driving environment. ( P. 5 0 0 )
*2: The master warning light turns on and the buzzer sounds in accordance
with the warning message.
Q AdBlue™ gauge
The quantity of AdBlue™ remaining in the tank is displayed on the multi-infor-
mation display. ( P. 1 3 7 )

Maintenance and care
WARNING
QProper inflation is critical to save tire performance
Keep your tires properly inflated.
If the tires are not properly inflated, the following conditions may occur
which could lead to an accident resulting in death or serious injury:
O Excessive wear
O Uneven wear
O Poor handling
O Possibility of blowouts resulting from overheated tires
O Air leaking from between tire and wheel
O Wheel deformation and/or tire damage
O Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges in the road, etc.)
NOTICE
Q When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or moisture may get into the valve and
cause an air leak, resulting in decreased tire inflation pressure.
