Driving
WARNING
●Even if the total load of occu-
pant’s weight and the cargo
load is less than the total load
capacity, do not apply the load
unevenly. Improper loading may
cause deteriorat ion of steering
or braking control which may
cause death or serious injury.
■When using a roof luggage
carrier (vehicles with roof
rails)
Observe the following precau-
tions:
●Place the cargo so that its
weight is distributed evenly
between the front and rear
axles.
●If loading long or wide cargo,
never exceed the vehicle overall
length or width. (
P.474)
●Before driving, make sure the
cargo is securel y fastened on
the roof luggage carrier.
●Loading cargo on the roof lug-
gage carrier will make the cen-
ter of gravity of the vehicle
higher. Avoid high speeds, sud-
den starts, sharp turns, sudden
braking or abrupt maneuvers,
otherwise it may result in loss of
control or vehicle rollover due to
failure to operate this vehicle
correctly and resu lt in death or
serious injury.
●If driving for a long distance, on
rough roads, or at high speeds,
stop the vehicle now and then
during the trip to make sure the
cargo remains in its place.
●Do not exceed 165 lb. (75 kg)
cargo weight on the roof lug-
gage carrier.
NOTICE
■When loading cargo
Be careful not to scratch the sur-
face of the moon roof or pan-
oramic moon roof.

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.398)
Wheels
If a wheel is bent, cracked or
heavily corroded, it should
be replaced. Otherwise, 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 acci-
dent, 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 tight-
ened, 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 accident and
resulting in death or serious injury.
Remove any oil or grease from
the wheel bolts or wheel nuts.
■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, pos-
sibly causing an accident.
NOTICE
■Replacing tire pressure warn-
ing valves and transmitters
●Because tire repair or replace-
ment may affect the tire pres-
sure warning valves and
transmitters, make sure to have
tires serviced by your Toyota
dealer or other qualified service
shop. In additio n, make sure to
purchase your tire pressure
warning valves and transmit-
ters at your Toyota dealer.

This information has been pre-
pared in accordance with regu-
lations issued by the National
Highway Traffic Safety Adminis-
tration of the U.S. Department of
Transportation.
It provides the purchasers
and/or prospective purchasers
of Toyota vehicles with informa-
tion on uniform tire quality grad-
ing.
Your Toyota dealer will help answer
any questions you may have as you
read this information.
■DOT quality grades
All passenger vehicle tires must
conform to Federal Safety
Requirements in addition to
these grades. Quality grades
can be found where applicable
on the tire sidewall between
tread shoulder and maximum
section width.
For example: Treadwear 200 Trac-
tion AA Temperature A
■Treadwear
The treadwear grade is a com-
parative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course.
For example, a tire graded 150 would wear one and
a half (1 - 1/2)
times as well on the government
course as a tire graded 100.
The relative performance of tires
depends upon the ac tual conditions
of their use. Performance may differ
significantly from the norm due to
variations in driving habits, service
practices and diff erences in road
characteristic s and climate.
■Traction AA, A, B, C
The traction grades, from high-
est to lowest, are AA, A, B and
C, and they represent the tire’s
ability to stop on wet pavement
as measured under controlled
conditions on specified govern-
ment test surfaces of asphalt
and concrete.
A tire marked C may have poor
traction performance.
Warning: The traction grade
assigned to this tire is based on
braking (straight ahead) traction
tests and does not include corner-
ing (turning) traction.
■Temperature A, B, C
The temperature grades are A
(the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure.
