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)

■Refilling AdBlue™
● Use AdBlue™ (compliant with ISO 22241-1).
AdBlue™ is a trademark of the German Association of the Automotive
Industry (VDA).
● Before driving for a long period of time in an area where AdBlue™ cannot
be refilled, consult any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
■ Warning message
If the following warning message is displayed on the multi-information dis-
play, follow the appropriate troubleshooting procedure.

WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accident resulting
in death or serious injury.
● Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
● Do not use tire sizes other than those recommended by Toyota.
● Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
● Do not mix summer, all season and snow tires.
● Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
NOTICE
■ Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the
cushioning ability of the tires. In addition, driving on rough roads may cause
damage to the tires themselves, as well as the vehicle’s wheels and body.
■ If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

5947-3. Do-it-yourself maintenance
HILUX_OM_OM0K321E_(EE)
WARNING
■Proper 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:
● Excessive wear
● Uneven wear
● Poor handling
● Possibility of blowouts resulting from overheated tires
● Air leaking from between tire and wheel
● Wheel deformation and/or tire damage
● Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges in the road, etc.)
NOTICE
■ 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.

5967-3. Do-it-yourself maintenance
HILUX_OM_OM0K321E_(EE)
WARNING
■When replacing wheels
● Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in a loss of handling control.
● Never use an inner tube in a leaking wheel which is designed for a tube-
less tire. Doing so may result in an accident, causing death or serious
injury.
■ When installing the wheel nuts
● Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, causing an acci-
dent and resulting in death or serious injury. Remove any oil or grease
from the wheel bolts or wheel nuts.
■ Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an
accident.
● Be sure to install the wheel nuts with the
tapered ends facing inward. Installing
the nuts with the tapered ends facing
outward can cause the wheel to break
and eventually cause the wheel to come
off while driving, which could lead to an
accident resulting in death or serious
injury.
