WARNING
■To prevent burns or damage on your vehicle
NOTICE
■To prevent damage to your vehicle
● Do not turn the heater on and off repeatedly in 5 minute intervals as this
can shorten the life of the heater components. If the engine must be turned
on and off repeatedly within short intervals (such as when the vehicle is
being used for delivery purposes), turn the heater off.
● Do not modify or open the heater without consulting any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer. This may
cause a heater malfunction or a fire.
● Be careful not to splash water or spill liquid directly on the heater or on the
heater fuel pump. This may cause the heater to malfunction.
● Keep the intake and exhaust pipes of the heater free from water, snow,
ice, mud, etc. If the pipes become clogged, this can cause the heater to
malfunction.
● If you notice anything unusual, such as a fluid leak, smoke or poor opera-
tion, turn off the heater and have your vehicle checked by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
● Do not touch the heater or its exhaust
pipe as they are hot.
● Keep flammable items such as fuel
away from the heater and its exhaust
pipe. This may cause a fire.

■Where to go for maintenance service?
In order to maintain your vehicle in the highest possible condition, Toyota rec-
ommends 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 dealers 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 authorized 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 repair?
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 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 driving straight on a level road
●Strange noises related to suspension movement
●Loss of brake effectiveness, spongy feeling brake 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.

■If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, engine coolant reservoir cap, drain cock
and water pump.
If you cannot find a leak, have any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer, test the cap and check for leaks in the
cooling system.
■ Coolant selection
Gasoline engine
Only use “Toyota Super Long Life Cool ant” or 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. (Enabled: -35 C [-31F])
Diesel engine
Only use “Toyota Genuine Premium Long Life Coolant 1WW/2WW” or equiv-
alent. “Toyota Genuine Premium Long Life Coolant 1WW/2WW” concen-
trated product always needs to be mixed as 50% coolant and 50% deionized

■ When adding engine 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.
