Driving
If the vehicle is parked without
setting the parking brake,
confirm that the shift position
cannot be moved out of P.
 If the vehicle is left parked
with the brakes damp in cold
temperatures, there is a pos-
sibility of the brakes freezing.
Vehicles without 195/50R19
tires
Use the correct tire chain size
when mounting the tire chains.
Chain size is regulated for each
tire size.
Side chain:
0.12 in. (3 mm) in diameter
0.39 in. (10 mm) in width
1.18 in. (30 mm) in length
Cross chain: 0.16 in. (4 mm) in diameter
0.55 in. (14 mm) in width
0.98 in. (25 mm) in length
Vehicles with 195/50R19 tires
Tire chains cannot be mounted.
Snow tires should be used
instead.
Regulations regarding the use
of tire chains vary depending on
location and type of road.
Always check local regulations
before installing chains.
■Tire chain installation
Observe the following precautions
when installing and removing
chains:
●Install and remove tire chains in a
safe location.
●Install tire chains on the front tires
only. Do not install tire chains on
the rear tires.
●Install tire chains on front tires as
tightly as possible. Retighten
chains after driving 1/4 - 1/2 mile
(0.5 - 1.0 km).
●Install tire chains following the
instructions provid ed with the tire
chains.
WARNING
■When parking the vehicle
When parking the vehicle without
applying the parking brake, make
sure to chock the wheels. If you
do not chock the wheels, the vehi-
cle may move unexpectedly, pos-
sibly resulting in an accident.

5347-3. Do-it-yourself maintenance
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.532, 535)
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 accident, causing
death or serious injury.
■When installing the wheel
nuts
●Be sure to install the wheel nuts
with the tapered ends facing
inward. ( P.530)
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 result-
ing in death or serious injury.
●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
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 cracked or deformed
wheels.
Doing so could cause the tire to
leak air during driving, possibly
causing an accident.
