Tire valve

Tire pressure gauge

Remove the tire valve cap.

Press the tip of the tire pressure gauge onto the tire valve.

Read the pressure using the gauge gradations.

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.

After completing the tire inflation pressure measurement and
adjustment, apply soapy water to the valve and check for leakage.

Put the tire valve cap back on.

■

Tire inflation pressure check interval

You should check tire inflation pressure 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 pressure, 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 judge if a tire is properly inflated based only on its appear-
ance.

●

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 vehicle 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 serious 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

●

Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges in the road, etc.)

NOTICE

■

When inspecting and adjusting 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.

When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width and
inset

*

.

Replacement wheels are available at your Toyota dealer.

*

:

Conventionally referred to as “offset”.

Toyota does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened

● Use only Toyota wheel nuts and 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 balance weights or equivalent and a plas-

tic or rubber hammer when balancing your wheels.

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.

6-3. Do-it-yourself maintenance

■

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 pressure.
Whenever wheels are replaced, tire pressure warning valves and trans-
mitters must be installed. (

→P. 343)

WARNING

■

When replacing wheels

●

Do not use wheels that are a different size from those recommended 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 seri-
ous 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 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.

●

Be sure to install the wheel nuts with
the tapered ends facing inward.
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
resulting in death or serious injury.

NOTICE

■

Replacing tire pressure warning valves and transmitters

●

Because tire repair or replacement may affect the tire pressure warn-
ing 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 transmitters at your
Toyota dealer.

●

Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly
with non-genuine wheels.

ter and replace it with a new
one.

■

Checking interval
Inspect and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, early replacement
may be required. (For scheduled maintenance information, please refer to the
“Schedule maintenance guide” or “Owner’s Manual Supplement”.)

■

If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.

■

Air conditioning filter deodorizing function
This vehicle is equipped with a deodorizing charcoal air filter to reduce odor
from the air conditioning system.

When items or products which emit fragrances or odors are placed in your
vehicle, the deodorizing effect may be significantly weakened in a short
period of time.

If frequent or strong odor comes from your air conditioning system, replace
the air conditioning filter.

NOTICE

■

When using the air conditioning system
Make sure that a filter is always installed.
Using the air conditioning system without a filter may cause damage to the
system.

After a fuse is replaced

●

If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. (

→P. 365)

●

If the replaced fuse blows again, have the vehicle inspected by your Toyota
dealer.

■

If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.

■

When replacing light bulbs
Toyota recommends that you use genuine 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.

WARNING

■

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 indicated, 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 your
Toyota dealer as soon as possible.
