If such devices are left connected, the engine switch may not be turned off
normally.
● Vehicles with Stop & Start system: When the engine restarts after having
been stopped by the Stop & Start system, the power outlet may be tempo-
rarily unusable, but this is not a malfunction.
NOTICE
● To avoid damaging the power outlets, close the power outlet lid when the
power outlet is not in use.
Foreign objects or liquids that enter the power outlet may cause a short
circuit.
● To prevent blown fuse:
12 V DC
Do not use an accessory that uses more than 12 V 10 A.
220 V AC
Do not use a 220 V AC appliance that requires more than 100 W.
If a 220 V AC appliance that consumes more than 100 W is used, the pro-
tection circuit will cut the power supply.
● To prevent battery discharge, do not use the power outlet longer than nec-
essary when the engine is not running.
● The following 220 V AC appliances may not operate properly even if their
power consumption is under 100 W:
• Appliances with high initial peak wattage
• Measuring devices that process precise data
• Other appliances that require an extremely stable power supply

Maintenance and care
HILUX_OM_OM0K789E_(EE)
■ Wheels and wheel ornaments
● Remove any dirt immediately by using a neutral detergent.
● Wash detergent off with water immediately after use.
● To protect the paint from damage, make sure to observe the following pre-
cautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the wheels when they are hot, such as after driv-
ing or parking in hot weather
■ Brake pads and calipers
Rust may form if the vehicle is parked with wet brake pads or disc rotors,
causing them to stick, or causing noi ses or vibrations. Before parking the
vehicle after it is washed, drive slowly and apply the brakes several times to
dry the parts.
■ Bumpers
Do not scrub with abrasive cleaners.
■ Plated portions
If dirt cannot be removed, clean the parts as follows:
● Use a soft cloth dampened with an approximately 5% solution of neutral
detergent and water to clean the dirt off.
● Wipe the surface with a dry, soft cloth to remove any remaining moisture.
● To remove oily deposits, use alcohol wet wipes or a similar product.
■ Painted brake calipers (if equipped)
● When using detergent, please use neutral detergent.
Do not use abrasive detergent or hard brushes, as they will damage the
paint.
● Do not use detergent when the brake caliper is hot.
● Wash detergent off with water immediately after use.
WARNING
■When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components etc. to catch fire.
■ Precautions regarding the exhaust pipe
Exhaust gases cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has
cooled sufficiently, as touching a hot exhaust pipe can cause burns.

■Where 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.
■ 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:
● 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 system 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 driven straight on a level road
● Strange noises related to suspension movement
● Loss of brake effectiveness, spongy feeling brake pedal or clutch 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.

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.
■ When working on the engine compartment
● Keep hands, clothing and tools away from the moving fan and engine
drive belt.
● 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.
● Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
● 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.
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.
NOTICE
■ 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.
■ 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.
