Operation of each component
HILUX_OM_OM0K513E_(EE)
Q If you lose your keys
New genuine keys can be made by any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer using a master key (vehicles with-
out smart entry & start system) or the other key of the same type (vehicles
with smart entry & start system), and the key number stamped on your key
number plate. Keep the plate in a safe place such as your wallet, not in the
vehicle.
Q When riding in an aircraft (type B and C)
When bringing a key with wireless remote control function onto an aircraft,
make sure you do not press any buttons on the key while inside the aircraft
cabin. If you are carrying the key in your bag etc., ensure that the buttons are
not likely to be pressed accidentally. Pressing a button may cause the key to
emit radio waves that could interfere with the operation of the aircraft.
Q Key battery depletion
Vehicles without smart entry & start system
If the wireless remote control function does not operate, the battery may be
depleted. Replace the battery when necessary. ( P. 516)
Vehicles with smart entry & start system
 P. 168
Q If a message regarding the state of the electronic key or engine switch
mode, etc. is shown
To prevent trapping the electronic key in side the vehicle, leaving the vehicle
without turning off the engine switch or other passengers from unintentionally
taking the key out of the vehicle, etc., a message that prompts the user to
confirm the state of the electronic key or engine switch mode may be shown
on the multi-information display. In those cases, follow the instructions on the
display immediately.
Q If “Key battery low” is shown on the multi-information display
The electronic key has a low battery. Replace the electronic key battery.
Q Replacing the electronic key battery

O When the electronic key battery is depleted
O Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electrical
noise

• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
O When multiple electronic keys are in the vicinity
O When other wireless keys (that emit radio waves) are being used nearby
O When carrying the electronic key together with the following devices that
emit radio waves
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or pers onal digital assistants (PDAs)

mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.

Maintenance and care
WARNING
QIf your vehicle is not properly maintained
Improper maintenance could result in serious damage to the vehicle and

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.
