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.

need replacement. ( P. 583)
● 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.

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.

Maintenance and care
WARNING
■Replacing light bulbs
● Turn off the lights. Do not attempt to replace the bulb immediately after
turning off the lights.
The bulbs become very hot and may cause burns.
● Do not touch the glass portion of the light bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clean dry cloth
to avoid getting moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.
● Fully install light bulbs and any parts used to secure them. Failure to do so
may result in heat damage, fire, or water entering the headlight unit. This
may damage the headlights or cause condensation to build up on the lens.
● Do not attempt to repair or disassemble light bulbs, connectors, electric
circuits or component parts.
Doing so may result in death or serious injury due to electric shock.
■ To prevent damage or fire
● Make sure bulbs are fully seated and locked.
● Check the wattage of the bulb before installing to prevent heat damage.

WARNING
■If the engine has to be turned off while driving
● Power assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the engine.
● Vehicles without smart entry & start system: Never attempt to remove the
key, as doing so will lock the steering wheel.

■While towing
If the engine is not running, the power assist for the brakes and steering will
not function, making steering and braking more difficult.
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When towing the vehicle
■ While towing
● When towing using cables or chains, avoid sudden starts, etc. which place
excessive stress on the towing hooks, cables or chains. The towing hooks,
cables or chains may become damaged, broken debris may hit people,
and cause serious damage.
● Do not turn the engine switch to the “LOCK” position (vehicles without
smart entry & start system) or off (vehicles with smart entry & start sys-
tem).
There is a possibility that the steering wheel is locked and cannot be oper-
ated.
Pre Runner (2WD models): Be sure to
transport the vehicle with all four wheels
raised off the ground. If the vehicle is
towed with the tires contacting the
ground, the drivetrain and related parts
may be damaged or an accident may
occur due to a change in direction of the
vehicle.
4WD models: Be sure to transport the
vehicle with all four wheels raised off the
ground. If the vehicle is towed with the
tires contacting the ground, the drivetrain
and related parts may be damaged, and
the vehicle may fly off the truck.
