Clean the wheels as you would the
rest of the exterior. Wash them with
thesamesolution,andrinsethem
thoroughly.
Aluminum alloy wheels have a
protective clear-coat that keeps the
aluminum from corroding and
tarnishing. Cleaning the wheels with
harsh chemicals (including some
commercial wheel cleaners) or a stiff
brush can damage the clear-coat. To
clean the wheels, use a mild
detergent and a soft brush or sponge. To
safely operate your vehicle, your
ti res must be the proper type and
size, in good condition with adequate
tread, and correctly inflated.
The following pages give more
detailed information on how to take
care of your tires and what to do
when they need to be replaced. Keeping
the tires properly inflated
provides the best combination of
handling, tread life, and riding
comfort.
Underinflated tires wear unevenly,
adversely affect handling and fuel
economy, and are more likely to
fail from being overheated.
Overinflated tires can make your
vehicleridemoreharshly,are
more prone to damage from road
hazards, and wear unevenly.

(TPMS)willwarnyouwhenatire

Using tires that are excessively
worn or improperly inflated can
cause a crash in which you can
be seriously hurt or killed.
Follow all instructions in this
owner’s manual regarding tire
inflation and maintenance.

Even though your vehicle is
equipped with TPMS, we
recommend that you visually check
your tires every day. If you think a
tire might be low, check it
immediately with a tire gauge.
Use a gauge to measure the air
pressure in each tire at least once a
month. Even tires that are in good
condition may lose 1 to 2 psi (10 to
20 kPa, 0.1 to 0.2 kgf/cm ) per
month. Remember to check the
sparetireatthesametime. If
you check air pressures when the
tires are hot [driven for several miles
(kilometers)], you will see readings 4
to6psi(30to40kPa,0.3 to0.4
kgf/cm ) higher than the cold
readings. This is normal. Do not let
air out to match the recommended
cold air pressure. The tire will be
underinflated.
While tubeless tires have some
ability to self-seal if they are
punctured, you should look closely
for punctures if a tire starts losing
pressure. Youshoulduseyourowntire
pressure gauge whenever you check
your tire pressu res. This will make it
easier for you to tell if a pressure
loss is due to a tire problem and not
due to a variation between gauges. The following chart shows the
recommended cold tire pressures f or
most normal and high-speed driving
conditions.
For additional inf ormation about
your tires, see page . For convenience, the recommended
tire sizes and cold tire pressures are
on a label on the driver’s doorjamb. Thecompactsparetirepressureis:
Check the air pressures when the
tires are cold. This means the
vehicle has been parked f or at least 3
hours, or driven less than 1 mile (1.6
km). Add or release air, if needed, to
match the recommended cold tire
pressures. 412

To help increase tire lif e and
distribute wear more evenly, rotate
the tires according to the
maintenance messages displayed on
the inf ormation display or multi-
inf ormation display (depending on
models). Move the tires to the
positions shown in the diagram each
time they are rotated. If you
purchase directional tires, rotate
only f ront-to-back.Replace your tires with radial tires of
the same size, load range, speed
rating, and maximum cold tire
pressure rating (as shown on the
tire’s sidewall).
Mixing radial and bias-ply tires on
your vehicle can reduce braking
ability, traction, and steering
accuracy. Using tires of a dif f erent
size or construction can cause the
ABS and vehicle stability assist
system (VSA) to work inconsistently.
TheABSworksbycomparingthe
speed of the wheels. When replacing
tires, use the same size originally
supplied with the vehicle. Tire size
and construction can affect wheel
speed and may cause the system to
activate.
It is best to replace all f our tires at
thesametime.If thatisnotpossible
or necessary, replace the two f ront
tires or two rear tires as a pair.
Replacing just one tire can seriously
af f ect your vehicle’s handling.
If you ever replace a wheel, make
sure the new one matches the
specif ications of the original.
Replacement wheels are available at
your dealer.

Use the compact spare tire as a
temporary replacement only. Get
your regular tire repaired or replaced,
and put it back on your vehicle as
soon as you can.
Check the inf lation pressure of the
compact spare tire every time you
check the other tires. It should be
inf lated to:Replace the tire when you can see
the tread wear indicator bars. The
replacement should be the same size
and design tire, mounted on the
same wheel. The spare tire is not
designed to be mounted on a regular
wheel, and the spare wheel is not
designed f or mounting a regular tire.
Follow these precautions:
Never exceed 50 mph (80 km/h).
This tire gives a harsher ride and
less traction on some road
surf aces. Use greater caution
while driving.
Do not mount snow chains on the
compact spare tire.
Do not use your compact spare
tire on another vehicle unless it is
thesamemakeandmodel.
Do not use the compact spare tire
if you are towing a trailer.

The tires that came on your vehicle
have a number of markings. Those
you should be aware of are described
below.
Speed symbol (an
alphabetical code indicating
the maximum speed rating). Load index (a numerical code
associated with the maximum
load the tire can carry).
Whenever tires are replaced, they
should be replaced with tires of the
same size. Below is an example of
tire size with an explanation of what
each component means. Tire width in millimeters.
Aspect ratio (the tire’s section
height as a percentage of its
width).
Tire construction code (R
indicates radial).
Rim diameter in inches. The tire identif ication number (TIN)
is a group of numbers and letters
that look like the f ollowing example
TIN. TIN is located on the sidewall
of the tire.
Max Load The maximum load the
tire can carry at maximum air
pressure. Max Press The maximum air
pressurethetirecanhold.
Date of manuf acture.
Tire type code. Manuf acturer’s
identification mark.
This indicates that the tire
meets all requirements of
the U.S. Department of
Transportation.

Each tire, including the spare (if
provided), should be checked
monthly when cold and inf lated to
the inf lation pressure recommended
by the vehicle manuf acturer on the
vehicle placard or tire inf lation
pressure label.
(If your vehicle has tires of a
dif f erent size than the size indicated
on the vehicle placard or tire
inf lation pressure label, you should
determine the proper tire inf lation
pressure f or those tires.)As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale
when one or more of your tires is
signif icantly under-inf lated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inf late them to
the proper pressure.Driving on a signif icantly
underinf lated tire causes the tire to
overheat and can lead to tire failure.
Underinf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire
maintenance, and it is the driver’s
responsibility to maintain correct tire
pressure, even if under-inf lation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
