Rear Window DefoggerThe rear window defogger clears fog,
frost, and thin ice from the window.
Push the defogger button to turn it on
and off. The indicator in the button
comes on to show the defogger is on. If
you do not turn it off, the defogger will
shut itself off within about 5 to 30
minutes according to the outside
temperature. It also shuts off when you
turn off the ignition switch. You have to
turn it on again when you restart the
vehicle.
In cold weather, the defogger will not
automatically shut itself off. You must
manually shut off the rear window
defogger when it is no longer
needed.
Make sure the rear window is clear
and you have good visibility before
starting to drive.
The defogger wires on the inside of
the rear window can be accidentally
damaged. When cleaning the glass,
always wipe side-to-side.
Pushing this button also turns the
mirror heaters on or off. For more
information, see page 147.Hazard Warning Button
Push the button between the center
vents to turn on the hazard warning
lights (four-way flashers). This
causes all outside turn signals and
both indicators in the instrument
panel to flash. Use the hazard
warning lights if you need to park in
a dangerous area near heavy traffic,
or if your vehicle is disabled.

If there is a problem with the TPMS,
the tire pressure monitor shows a
‘‘SYSTEM FUNCTION ERROR ’’
message and the tire pressure
readings are not displayed. If this
happens, you will first see a system
warning message ‘‘CHECK TPMS
SYSTEM ’’on the multi-information
display. TPMS System Failure
If there is a problem with the TPMS,
you will see the above message on
the multi-information display.
If you see this message, the system
is off and is not monitoring the tire
pressures. Have the system checked
by your dealer as soon as possible.
Also, the low tire pressure/TPMS
indicator begins to flash (see page
71).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 page 396). 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 page 454).
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. 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.

Check the condition of the battery
monthly by looking at the test
indicator window. The label on the
battery explains the test indicator's
colors.Check the terminals for corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it off with plain
water. Dry off the battery with a cloth
or paper towel. Coat the terminals
with grease to help prevent future
corrosion.
If additional battery maintenance is
needed, see your dealer or a
qualified technician.
WARNING:
Battery posts,
terminals, and related accessories
contain lead and lead compounds.
Wash your hands after handling.
If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle's
electrical system. Always disconnect
the negative (- ) cable first, and
reconnect it last.
The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt
you.
Wear protective clothing and a
face shield, or have a skilled
technician do the battery
maintenance.

If you have a flat tire while driving,
stop in a safe place to change it.
Drive slowly along the shoulder until
you get to an exit or an area that is
far away from the traffic lanes.
The vehicle can easily roll off
the jack, seriously injuring
anyone underneath.
Follow the directions for
changing a tire exactly, and
never get under the vehicle
when it is supported only by the
jack.1. Park the vehicle on firm, level, and
non-slippery ground. Put the
transmission in Park. Apply the
parking brake.
If you are towing a trailer, unhitch
it.
2. Turn on the hazard warning lights, and turn the ignition switch to the
LOCK (0) position. Have all
passengers get out of the vehicle
while you change the tire.
3. Open the tailgate. Raise the cargoarea floor lid by lifting it up with
the strap, then remove the lid.
The spare tire, jack, and tools are
under the cargo area floor.
4. Unscrew the wing bolt. Use the hooked end of the wheel nut
wrench extension as a wrench if
the wing bolt is hard to loosen.
Then take the spare tire out of the
cargo area.WING BOLT

The reading of the vehicle's
temperature gauge on the multi-
information display should stay in the
midrange. If it climbs to the H (Hot)
mark, you should determine the
reason (hot day, driving up a steep
hill, etc.).
If the coolant temperature rises to
224°F (118°C) or more, the
temperature gauge will appear on the
display and blink for several times.
At the same time, the beeper will
sound once.
If your vehicle overheats, you should
take immediate action. The only
indication may be the temperature
gauge climbing to the H (Hot) mark.
Or you may see steam or spray
coming from under the hood.
Driving with the temperature gauge
reading at the H (Hot) mark can cause
serious damage to the engine.
Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
1. Safely pull to the side of the road. Put the transmission in Park, and
set the parking brake. Turn off all
accessories, and turn on the
hazard warning lights. 2. If you see steam and/or spray
coming from under the hood, turn
off the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
3. If you do not see steam or spray, leave the engine running and
watch the temperature gauge. If
the high heat is due to
overloading, the engine should
start to cool down almost
immediately. If it does, wait until
the temperature gauge comes
down to the midpoint, then
continue driving.
4. If the temperature gauge reading stays at the H (Hot) mark, turn off
the engine.
