Blown fuse
■After a fuse is replaced
●When installing the lid, make sure that
the tab is installed securely.
●If the lights do not turn on even after
the fuse has been replaced, a bulb
may need replacement. ( P.497)
●If the replaced fuse blows again, have
the vehicle inspected by any author- ized Toyota retailer or Toyota author-
ized repairer, or any reliable repairer.
■If there is an overload in a circuit
The fuses are designed to blow, protect- ing the wiring harness from damage.
■When replacing light bulbs
Toyota recommends that you use genu-
ine Toyota products designed for this vehicle.
Because certain bulbs are connected to
circuits designed to prevent overload, non-genuine parts or parts not designed
for this vehicle may be unusable.
WA R N I N G
■To prevent system breakdowns
and vehicle fire
Observe the following precautions.
Failure to do so may cause damage
to the vehicle, and possibly a fire or injury.
●Never use a fuse of a higher amperage rating than that indi-
cated, 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.
●Do not modify the fuses or fuse
boxes.
NOTICE
■Before replacing fuses
Have the cause of electrical overload
determined and repaired by any authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer as soon as possible.

■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 light unit. This may damage the lights or
cause condensation to build up on
the lens.
■To prevent damage or fire
Make sure bulbs are fully seated and locked.

●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 possi- ble before turning off the engine.

If your vehicle needs to
be towed
If towing is necessary, we rec-
ommend having your vehicle
towed by any authorized
Toyota retailer or Toyota
authorized repairer, or any reli-
able repairer or commercial
towing service, using a
wheel-lift type truck or flatbed
truck.
Use a safety chain system for
all towing, and abide by all
state/provincial and local laws.
WA R N I N G
Observe the following precautions. Failure to do so may result in death or
serious injury.
■When towing the vehicle
Be sure to transport the vehicle with
the front wheels raised or with all four wheels raised off the ground. If the
vehicle is towed with the front wheels
contacting the ground, the drivetrain and related parts may be damaged.
■While towing
●When towing using cables or
chains, avoid sudden starts, etc.
which place excessive stress on the towing eyelets, cables or chains.
The towing eyelets, cables or
chains may become damaged, bro- ken debris may hit people, and
cause serious damage.
●Do not turn the engine switch off.
There is a possibility that the steer-
ing wheel is locked and cannot be operated.
■Installing towing eyelets to the vehicle
Make sure that towing eyelets are
installed securely. If not securely installed, towing eye-
lets may come loose during towing.
NOTICE
■To prevent damage to the vehicle
when towing using a wheel-lift type truck
●Vehicles without a smart entry &
start system: Do not tow the vehicle from the rear when the engine
switch is off or the key is removed.
The steering lock mechanism is not strong enough to hold the front
wheels straight.
●Vehicles with a smart entry & start
system: Do not tow the vehicle from
the rear when the engine switch is off. The steering lock mechanism is
not strong enough to hold the front
wheels straight.
●When raising the vehicle, ensure
adequate ground clearance for tow- ing at the opposite end of the raised
vehicle. Without adequate clear-
ance, the vehicle could be dam- aged while being towed.

When trouble arises
When using a flat-bed truck to
transport the vehicle, use tire strap-
ping belts. Refe r to the owner's
manual of the flat-bed truck for the
tire strapping method.
In order to suppress vehicle move-
ment during transportation, set the
parking brake and turn the engine
switch off.
If a tow truck is not available in an
emergency, your vehicle may be
temporarily towed using cables or
chains secured to the emergency
towing eyelets. This should only be
attempted on hard surfaced roads
for at most 80 km (50 miles) at
under 30 km/h (18 mph).
A driver must be in the vehicle to
steer and operate the brakes. The
vehicle’s wheels, drive train, axles,
steering and brakes must be in
good condition.
For vehicles with a Multidrive, only
the front towing eyelets may be
used.
To have your vehicle towed by
another vehicle, the towing eyelet
must be installed to your vehicle.
Install the towing eyelet using the
following procedure.
1 Take out the wheel nut wrench
(if equipped) and towing eyelet.
( P.524, 540)
2 Remove the eyelet cover using
a flathead screwdriver.
To protect the bodywork, place a rag
between the screwdriver and the vehi- cle body as shown in the illustration.

■When fixing the flat tire
●Stop your vehicle in a safe and flat
area.
●Do not touch the wheels or the area
around the brakes immediately after the vehicle has been driven.
After the vehicle has been driven,
the wheels and the area around the
brakes may be extremely hot. Touching these areas with hands,
feet or other body parts may result
in burns.
●Connect the valve and hose
securely with the tire installed on the vehicle. If the hose is not prop-
erly connected to the valve, air
leakage may occur as sealant may be sprayed out.
●If the hose comes off the valve while inflating the tire, there is a risk
that the hose will move abruptly due
to air pressure.
●After inflation of the tire has com-
pleted, the sealant may splatter when the hose is disconnected or
some air is let out of the tire.
●Follow the operation procedure to
repair the tire. If the procedures not
followed, the sealant may spray out.
●Keep back from the tire while it is
being repaired, as there is a chance of it bursting while the repair opera-
tion is being performed. If you
notice any cracks or deformation of
the tire, turn off (type A) or (off)
(type B) the compressor switch and
stop the repair operation immedi- ately.
●The repair kit may overheat if oper-ated for a long period of time. Do
not operate the repair kit continu-
ously for more than 40 minutes.
●Parts of the repair kit become hot during operation. Be careful when
handling the repair kit during and
after operation. Do not touch the metal part around the connecting
area between the bottle and com-
pressor. It will be extremely hot.
●Do not attach the vehicle speed
warning sticker to an area other than the one indicated. If the sticker
is attached to an area where an
SRS airbag is located, such as the pad of the steering wheel, it may
prevent the SRS airbag from oper-
ating properly.
●To avoid risk of burst or severe
leakage, do not drop or damage the bottle. Visually inspect the bottle
before use. Do not use a bottle with
shock, crack, scratch, leakage or any other damage. In such case,
immediately replace.
■Driving to spread the liquid seal-
ant evenly
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of
vehicle control and cause death or serious injury.
●Drive the vehicle carefully at a low speed. Be especially careful when
turning and cornering.
●If the vehicle does not drive straight
or you feel a pull through the steer-
ing wheel, stop the vehicle and check the following.
• Tire condition. The tire may have
separated from the wheel.
• Tire inflation pressure. If the tire
inflation pressure is 130 kPa (1.3
kgf/cm2 or bar, 19 psi) or less, the tire may be severely damaged.
