Although your tire pressure is
monitored, you must manually check
thetirepressuresmonthly.
Each tire, including the spare, should
be checked monthly when the
vehicle is cold, and set to the
recommended inf lation pressure as
specif ied on the vehicle placard and
intheowner’smanual(seepage).
If the tire is f lat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire (see page ).
If you think you can saf ely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure. If you have a f lat tire, the low tire
pressure/TPMS and tire monitor
indicators will come on. Replace the
indicated f lat tire with the compact
sparetire(seepage ).
After the flat tire is replaced with the
spare tire, the low tire pressure/
TPMS indicator stays on while
driving. Af ter several miles
(kilometers) driving, this indicator
begins to f lash, then stays on again.
You will also see a ‘‘CHECK TPMS
SYSTEM’’ message on the multi-
inf ormation display. This is normal;
the system cannot monitor the spare
tire pressure. Manually check the
sparetirepressuretobesureitis
correct.
This indicator and the warning
message on the multi-inf ormation
display will go of f , af ter several miles
(kilometers) driving, when the spare
tire is replaced with the specifiedregular tire equipped with the tire
pressure monitor sensor.
Never use a puncture-repairing agent
in a f lat tire. If used, you will have to
replace the tire pressure sensor.
Havetheflattirerepairedbyyour
dealer as soon as possible.
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specif ic wheels. It is
recommended that you always have
your tires serviced by your dealer or
a qualif ied technician.

Many states and Canadian provinces
require special outside mirrors when
towing a trailer. Even if they don’t,
you should install special mirrors if
you cannot clearly see behind you, or
if the trailer creates a blind spot.
Askyourtrailersalesorrental
agency if any other items are
recommended or required f or your
towing situation.When preparing to tow, and bef ore
driving away, be sure to check the
f ollowing:
Your vehicle tires and spare are
properly inf lated, and the trailer
tires and spare are inflated as
recommended by the trailer
maker.
The vehicle has been properly
serviced, and the suspension and
the cooling system are in good
operating condition.
The trailer has been properly
serviced and is in good condition,
and the lights and brakes on the

pressure gauge and use it whenever
you check your tire pressures. This
will make it easier f or you to tell if a
pressure loss is due to a tire problem
and not due to a variation between
gauges.While tubeless tires have some
ability to self -seal if they are
punctured, you should look closely
f or punctures if a tire starts losing
pressure.
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 one to two psi (10
to 20 kPa, 0.1 to 0.2 kgf /cm ) per
month. Remember to check the
sparetireatthesametime.
Check the pressure in the tires when
they are cold. This means the vehicle
has been parked f or at least three
hours, or driven less than 1 mile (1.6
km).
Add or release air, if needed, to
match the recommended cold tire
pressures on page .

The last four digits of the TIN (tire
identif ication number) are f ound on
the sidewall of the tire and indicate
the date of manufacture (Seeon page ).
The service lif e of your tires is
dependent on many f actors,
including, but not limited to, driving
habits, road conditions, vehicle
loading, inf lation pressure,
maintenance history, speed, and
environmental conditions (even
when the tires are not in use). In addition to your regular
inspections and inf lation pressure
maintenance, it is recommended that
you have annual inspections
perf ormed once the tires reach f ive
years old. It is also recommended
that all tires, including the spare, be
removed from service after 10 years
from the date of manufacture,
regardless of their condition or state
of wear.

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
samewheel.Thesparetireisnot
designed to be mounted on a regular
wheel, and the spare wheel is not
designed f or mounting a regular tire.
Do not mount snow chains on the
compact spare tire.
Do not use your compact spare
tire on another vehicle unless it is
thesamemakeandmodel.
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.
After the flat tire is replaced with
the spare tire, the low tire
pressure/TPMS indicator stays on.
Af ter several miles (kilometers)
driving with the spare, this
indicator begins to f lash, then
stays on again. You will also see a

message on the multi-inf ormation
