Maintenance and care
WARNING
■Chemicals in the battery
Batteries contain poisonous and corrosive sulfuric acid and may produce
hydrogen gas which is flammable and explosive. To reduce the risk of death
or serious injury, take the following precautions while working on or near the
battery:
● Do not cause sparks by touching the battery terminals with tools.
● Do not smoke or light a match near the battery.
● Avoid contact with eyes, skin and clothes.
● Never inhale or swallow electrolyte.
● Wear protective safety glasses when working near the battery.
● Keep children away from the battery.
■ Where to safely charge the battery
Always charge the battery in an open area. Do not charge the battery in a
garage or closed room w here there is insufficient ventilation.
■ How to recharge the battery (vehicles with maintenance-free type bat-
tery)
Only perform a slow charge (5 A or less). The battery may explode if
charged at a quicker rate.
■ Emergency measures regarding electrolyte
● If electrolyte gets in your eyes
Flush your eyes with clean water for at least 15 minutes and get immedi-
ate medical attention. If possible, continue to apply water with a sponge or
cloth while traveling to the nearest medical facility.
● If electrolyte gets on your skin
Wash the affected area thoroughly. If you feel pain or burning, get medical
attention immediately.
● If electrolyte gets on your clothes
It can soak through clothing on to your skin. Immediately take off the cloth-
ing and follow the procedure above if necessary.
● If you accidentally swallow electrolyte
Drink a large quantity of water or milk. Get emergency medical attention
immediately.
● When there is insufficient battery fluid
Do not use if there is insufficient fluid in the battery. There is a possible
danger that the battery may explode.
■ When disconnecting the battery
Do not disconnect the negative (-) terminal on the body. The disconnected
negative (-) terminal may touch the positive (+) terminal, which may cause a
short and result in death or serious injury.

Maintenance and care
You may drain the fuel filter yourself. However, as the operation is dif-
ficult, we recommend having it drained by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer. Even if
you decide to drain it yourself, contact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer.
The water in the fuel filter needs to be drained if one of the following
symptoms occurs:
Vehicles without multi-information display
When the fuel system warning light flashes and a buzzer sounds.
( P. 637)
Vehicles with multi-information display
When “WATER ACCUMULATION IN FUEL FILTER SEE
OWNER’S MANUAL”/“Water accumulation in fuel filter See owner’s
manual” is shown on the multi-information display and a buzzer
sounds*1.
Vehicles without smart entry & start system: Turn the engine switch
to the “LOCK” position.
Vehicles with smart entry & start system: Turn the engine switch off.
For EURO VI models*3:
Remove the fuel filter from the
bracket as shown in the illustra-
tion.
Place a small tray under the drain plug or drain hose to catch the
water and any fuel that comes out.

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.
● Vehicles without water-cooled intercooler:
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.
● Vehicles with water-cooled intercooler:
1.0 L (1.1 qt., 0.9 Imp.qt.) of AdBlue™ is consumed every 600 km
(373 miles). Normally, after a full refill, the vehicle can be driven for
approximately 8000 km (4971 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. 586)
When refilling AdBlue™ by
yourself in an emergency, be
sure to follow the correct refill-
ing procedures. ( P. 587)

Maintenance and care
Close the AdBlue™ tank cap.
Turn the cap until you hear a
click.
Check that the engine starts.
The way of refilling may differ from those shown in the illustration.
■ When refilling AdBlue™
After refilling AdBlue™, the engine may take a few seconds longer than nor-
mal to start.

NOTICE
■ When refilling AdBlue™
Observe the following precautions.
Failure to do so may result in damage to the vehicle parts, paint, etc.
● Do not use urea solution other than AdBlue™.
● If AdBlue™ comes into contact with any painted surfaces on the vehicle,
immediately wash the affected areas with water.
● If AdBlue™ is spilled inside the engine compartment, immediately wipe it
with a wet cloth.
■ When refilling AdBlue™ with the refilling equipment
Observe the following precautions to prevent AdBlue™ overflowing from the
AdBlue™ tank:
● Securely insert the nozzle into the AdBlue™ filler neck.
● Stop filling the tank after the nozzle automatically clicks off.
● Do not top off the AdBlue™ tank.
■ When storing AdBlue™ containers
Observe the following precautions.
Failure to do so may result in damage to vehicle parts, paint, etc., and
changes in the chemical compounds of AdBlue™ may cause unpleasant
odors.
● Do not leave AdBlue™ containers inside the vehicle.
● Tightly seal AdBlue™ containers and store them in a cool, dry location
with good ventilation and no exposure to direct sunlight.

■After a fuse is replaced
● If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. ( P. 607)
● If the replaced fuse blows again, have the vehicle inspected by any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■ If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
WARNING
■ To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or
injury.
● Never use a fuse of a higher amperage rating than that indicated, or use
any other object in place of a fuse.
● Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
● Do not modify the fuses or fuse boxes.
NOTICE
■Before replacing fuses
Have the cause of electrical overload determined and repaired by any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer as soon as possible.
