If the low tire pressure/TPMS
indicator comes on, or the multi-
information display shows a‘‘CHECK
TPMS SYSTEM ’’message, the VSA
system automatically turns on even
when the VSA system is turned off
by pressing the VSA OFF switch
(see page360).If this happens, you
cannot turn the VSA system off by
pressing the VSA OFF switch again.
When you restart the vehicle with
the compact spare tire, the TPMS
system message will also be
displayed on the multi-information
display after several miles
(kilometers) driving.
Changing a Tire with TPMS
If you have a flat tire, the low tire
pressure/TPMS and tire monitor
indicators will come on. Replace the
indicated flat tire with the compact
spare tire (see page425). After the flat tire is replaced with the
spare tire, the low tire pressure/
TPMS indicator stays on while
driving. After several miles
(kilometers) driving, this indicator
begins to flash, then stays on again.
You will also see a
‘‘CHECK TPMS
SYSTEM ’’message on the multi-
information display. This is normal;
the system cannot monitor the spare
tire pressure. Manually check the
spare tire pressure to be sure it is
correct. This indicator and the warning
message on the multi-information
display will go off, after several miles
(kilometers) driving, when the spare
tire is replaced with the specified
regular tire equipped with the tire
pressure monitor sensor.
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specific wheels. It is
recommended that you always have
your tires serviced by your dealer or
a qualified technician.
Never use a puncture-repairing agent
in a flat tire. If used, you will have to
replace the tire pressure sensor.
Have the flat tire repaired by your
dealer as soon as possible.

Use this illustration to identify each
terminal in the trailer brake
controller connector.
Safety ChainsAlways use safety chains when you
tow a trailer. Make sure the chains
are secured to the trailer and hitch,
and that they cross under the tongue
and can catch the trailer if it becomes
unhitched. Leave enough slack to
allow the trailer to turn corners
easily, but do not let the chains drag
on the ground.Sway ControlThis device is recommended if your
trailer tends to sway. Your trailer
maker can tell you what kind of sway
control you need and how to install it.Trailer MirrorsMany states and provinces require
special exterior 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.
Spare TiresWhen towing a trailer, we
recommend that you carry a full-size
spare wheel and tire for your vehicle
and trailer. See page419for proper
tire size, page425for how to store a
full size wheel and tire, and page425
for information on changing a flat
tire.
Remember to unhitch the trailer
before changing a flat. Ask your
trailer sales or rental agency where
and how to store the trailer's spare
tire.

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 inflation pressure of the
compact spare tire every time you
check the other tires. It should be
inflated to:
60 psi (420 kPa, 4.2 kgf/cm
2)
Follow these precautions:
●Never exceed 50 mph (80 km/h).●This tire gives a harsher ride and
less traction on some road
surfaces. Use greater caution while
driving.
●Do not mount snow chains on a
compact spare.●Do not use your compact spare tire
on another vehicle unless it is the
same make and model.●After the flat tire is replaced with
the spare tire, the low tire
pressure/TPMS indicator stays on.
After several miles (kilometers)
driving with the spare, this
indicator begins to flash, then
stays on again. You will also see a
‘‘ CHECK TPMS SYSTEM’’
message on the multi-information
display (see page354).
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 for mounting a regular tire.INDICATOR LOCATION MARK

22. Slowly turn the wheel nut wrenchclockwise to take up the slack of
the hoist cable. Make sure the
bracket is seated in the center hole
of the flat tire.
23. Turn the wheel nut wrench clockwise until the flat tire rests
against the underbody of the
vehicle and you hear the hoist
click.
Always raise the spare tire hoist, even if
you are not stowing a tire. If the hoist is
left down, it will be damaged during
driving and need to be replaced.
24. Store the jack in its holder. Turn the jack's end bracket to lock it in
place. Store the tools, and install
the cover.
25. Refer to Changing a Tire with
TPMS (see page355).
Loose items can fly around the
interior in a crash and could
seriously injure the occupants.
Store the wheel, jack, and tools
securely before driving.
