Maintenance and care
Tire pressure gauge
1 Remove the tire valve cap.
2 Press the tip of the tire pres-
sure gauge onto the tire
valve.
3 Read the pressure using the
gauge gradations.
4 If the tire inflation pressure is
not at the recommended
level, adjust the pressure.
If you add too much air, press
the center of the valve to
deflate.
5 After completing the tire infla-
tion pressure measurement
and adjustment, apply soapy
water to the valve and check
for leakage.
6 Put the tire valve cap back
on.
■Tire inflation pressure check
interval
You should check tire inflation pres-
sure every two weeks, or at least
once a month. Do not forget to
check the spare.
■Effects of incorrect tire inflation
pressure
Driving with incorrect tire inflation
pressure may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor
handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating,
have it checked by your Toyota
dealer.
■Instructions for checking tire
inflation pressure
When checking tire inflation pres-
sure, observe the following:
●Check only when the tires are
cold.
If your vehicle has been parked for
at least 3 hours or has not been
driven for more than 1 mile or 1.5
km, you will get an accurate cold
tire inflation pressure reading.
●Always use a tire pressure gauge.
It is difficult to j udge if a tire is
properly inflated based only on its
appearance.
●It is normal for the tire inflation
pressure to be higher after driving
as heat is generated in the tire. Do
not reduce tire inflation pressure
after driving.
●Never exceed the vehicle capacity
weight.
Passengers and luggage weight
should be placed so that the vehi-
cle is balanced.
WARNING
■Proper inflation is critical to
save tire performance
Keep your tires properly inflated.
If the tires are not properly
inflated, the following conditions
may occur which could lead to an
accident resulting in death or seri-
ous injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting
from overheated tires
●Air leaking from between tire
and wheel
●Wheel deformation and/or tire
damage

3446-3. 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, the tire pressure warning
valves and transmitters must be
installed. ( P.330)
WARNING
●Greater possibility of tire dam-
age while driving (due to road
hazards, expansion joints,
sharp edges in the road, etc.)
NOTICE
■When inspecting and adjust-
ing tire inflation pressure
Be sure to put the tire valve caps
back on.
If a valve cap is not installed, dirt
or moisture may get into the valve
and cause an air leak, resulting in
decreased tire inflation pressure.
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.

Maintenance and care
Use only Toyota wheel nuts
and wheel nut wrenches
designed for use with your
aluminum wheels.
 When rotating, repairing or
changing your tires, check
that the wheel nuts are still
tight after driving 1000 miles
(1600 km).
 Be careful not to damage the
aluminum wheels when using
tire chains.
 Use only Toyota genuine bal-
ance weights or equivalent
and a plastic or rubber ham-
mer when balancing your
wheels.
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 cracked 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 addition, make sure to
purchase your tire pressure
warning valves and transmit-
ters at your Toyota dealer.
●Ensure that only genuine Toyota
wheels are used on your vehi-
cle.
Tire pressure warning valves
and transmitters may not work
properly with non-genuine
wheels.
