Maintenance and care
When replacing wheels, care
should be taken to ensure that
they are equivalent to those
removed in load capacity, diam-
eter, rim width and inset
*.
Replacement wheels are avail-
able at your Toyota dealer.
*: Conventionally referred to as off- set.
Toyota does not recommend
using the following:
 Wheels of different sizes or
types
 Used wheels
 Bent wheels that have been
straightened
■When replacing wheels
The wheels of your vehicle are
equipped with tire pressure warning
valves and transmitters that allow
the tire pressure warning system to
provide advance warning in the
event of a loss in tire inflation pres-
sure. Whenever wheels are
replaced, tire pressure warning
valves and transmitters must be
installed. ( P.476)
Wheels
If a wheel is bent, cracked
or heavily corroded, it
should be replaced. Other-
wise, the tire may separate
from the wheel or cause a
loss of handling control.
Wheel selection
WARNING
■When replacing wheels
●Do not use wheels that are a dif-
ferent size from those recom-
mended 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 tubeless tire. Doing so may
result in an accident, causing
death or serious injury.
■Wheel bolts
Observe the following precautions
to reduce the risk of death or seri-
ous injury:
●Do not over tighten.
●Never use oil or grease on the
wheel bolts. Oil and grease may
cause the wheel bolts to be
excessively tightened, leading
to bolt or disc wheel damage. In
addition, the oil or grease can
cause the wheel bolts to loosen
and the wheel may fall off, caus-
ing a serious accident. Remove
any oil or grease from the wheel
bolts.
●If there are any cracks or defor-
mations in the wheel bolts, or if
the surface treatment becomes
worn, have the wheel bolts
replaced at your Toyota dealer.
Failure to follow these precau-
tions could cause the wheel
bolts to loosen and the tire to fall
off, resulting in death or serious
injury.
■Use of defective wheels pro-
hibited
Do not use cracke d or deformed
wheels.
Doing so could cause the tire to
leak air during driving, possibly
causing an accident.

When trouble arises
When using a flat-bed truck to
transport the vehicle, use tire
strapping belts. Refer to the
owner’s manual of the flat-bed
truck for the tire strapping
method.
In order to suppress vehicle
movement during transporta-
tion, set the parking brake and
turn the power 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 short
distances at under 18 mph (30
km/h).
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.
WARNING
AWD 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 or related
parts may be damaged, the vehi-
cle may fly off the truck, or elec-
tricity generated by the operation
of the motor may cause a fire to
occur depending on the nature of
the damage or malfunction.
NOTICE
■To prevent damage to the
vehicle when towing using a
wheel-lift type truck
When raising the vehicle, ensure
adequate ground clearance for
towing at the opposite end of the
raised vehicle. Without adequate
clearance, the vehicle could be
damaged while being towed.
■Towing with a sling-type truck
Do not tow with a sling-type truck
to prevent body damage.

■Emergency tire puncture repair
kit
●The sealant stored in the emer-
gency tire puncture repair kit can
be used only once to temporarily
repair a single tire. If the sealant in
the bottle and other parts of the kit
have been used and need to be
replaced, contact your Toyota
dealer.
●The compressor can be used
repeatedly.
●The sealant can be used when the
outside temperature is from -40°F
(-40°C) to 140°F (60°C).
●The kit is exclusi vely designed for
size and type of ti res originally
installed on your vehicle. Do not
use it for tires tha t a different size
than the original ones, or for any
other purposes.
●If the sealant gets on your clothes,
it may stain.
●If the sealant adhe res to a wheel
or the surface of the vehicle body,
the stain may not be removable if
it is not cleaned at once. Immedi-
ately wipe away the sealant with a
wet cloth.
●During operation of the repair kit,
a loud operation noise is pro-
duced. This does not indicate a
malfunction.
●Do not use to check or to adjust
the tire pressure.
■Note for checking the emer-
gency tire puncture repair kit
●Check the sealant expiry date
occasionally. The expiry date is
shown on the bottle.
●Do not use sealant whose expiry
date has already passed. Other-
wise, repairs conducted using the
emergency tire puncture repair kit
may not be performed properly.
●The sealant has a limited life
span. The expiry date is marked
on the bottle. The sealant should
