DPF (Diesel Particulate Filter) system
: If equipped
When the deposit collected by the filter reaches a predetermined
amount, it is automatically regenerated.
WARNING
Q During regeneration
Observe the following precautions.
Failure to do so may result in serious injury such as burns caused by the hot
exhaust pipe and exhaust gases, or may cause a fire.
O Do not carry out regeneration when the vehicle is in an enclosed area,
such as a garage.
O Do not touch the exhaust pipe and exhaust gases during regeneration.
NOTICE
QTo prevent the DPF system from failing
O Do not drive for long periods of time while the DPF system warning mes- sage “DPF full Visit your dealer” appears on the multi-information displayand a buzzer sounds (malfunction indicator lamp comes on)
O Do not use fuel other than the specified type
O Do not use engine oil other than the recommended type
O Do not modify the exhaust pipe
ODo not stop the vehicle where flamma-
ble materials, such as dry grass, are

Maintenance and care
WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become el ectrically energized. To avoid death
or serious injury, observe the following precautions.
Q When working on the engine compartment
O Keep hands, clothing and tools away from the moving fan and engine
drive belt.
O Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
O Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
O Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
O Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
O Take care because brake fluid can harm your hands or eyes and damage
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.
Q Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.
NOTICE
Q If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.
Q If 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 refilling, it may indicate a serious problem.

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. 569)
Vehicles with multi-information display
When “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.
Place a small tray under the drain plug or drain hose to catch the
water and any fuel that comes out.
Perform the draining as shown in the illustration.
Turn the drain plug counter-
clockwise about 2 to 2 1/2
turns.
Loosening more than this will
cause water oozing from around
the drain plug.
Operate the priming pump
until fuel begins to run out.
After draining, tighten the drain plug by hand.
