WARNING
■Chemicals in the battery
The battery contains poisonous
and corrosive sulfuric acid and
may produce hydrogen gas which
is flammable and explosive. To
reduce the risk of death or serious
injury, take the following precau-
tions while working on or near the
battery:
●Do not cause sparks by touch-
ing the battery terminals with
tools.
●Do not smoke or light a match
near the battery.
●Avoid contact with eyes, skin
and clothes.
●Never inhale or swallow electro-
lyte.
●Wear protective safety glasses
when working near the battery.
●Keep children away from the
battery.
■Where to safely charge the
battery
Always charge the battery in an
open area. Do not charge the bat-
tery in a garage or closed room
where there is insu fficient ventila-
tion.
■Emergency measures regard-
ing electrolyte
●If electrolyte gets in your eyes
Flush your eyes with clean
water for at least 15 minutes
and get immediate medical
attention. If possible, continue
to apply water with a sponge or
cloth while traveling to the near-
est medical facility.
●If electrolyte gets on your skin
Wash the affected area thor-
oughly. If you feel pain or burn-
ing, get medical attention
immediately.
●If electrolyte gets on your
clothes
It can soak through clothing on
to your skin. Immediately take
off the clothing and follow the
procedure above if necessary.
●If you accidentally swallow elec-
trolyte
Drink a large quantity of water
or milk. Get emergency medical
attention immediately.
■When disconnecting the bat-
tery
Do not disconnect the negative (-)
terminal on the body side. The
disconnected negative (-) terminal
may touch the positive (+) termi-
nal, which may cause a short and
result in death or serious injury.
NOTICE
■When recharging the battery
Never recharge the battery while
the engine is running. Also, be
sure all accessories are turned
off.

Maintenance and care
Front
To equalize tire wear and extend
tire life, Toyota recommends that
tire rotation is carried out at the
same interval as tire inspection.
Vehicles with a tire pressure warn-
ing system: Do not fail to initialize
the tire pressure warning system
after tire rotation.
Your vehicle is equipped with a
tire pressure warning system
that uses tire pressure warning
valves and transmitters to detect
low tire inflation pressure before
serious problems arise.
If the tire pressure drops below
a predetermined level, the driver
is warned by a warning light.
( P.485)
■Routine tire inflation pressure
checks
The tire pressure warning system
does not replace routine tire inflation
pressure checks. Make sure to
check tire inflation pressure as part
of your routine of daily vehicle
checks.
■Situations in which the tire
pressure warning system may
not operate properly
●In the following cases, the tire
pressure warning system may not
operate properly.
• If non-genuine Toyota wheels are used.
• A tire has been replaced with a tire that is not an OE (Original
Equipment) tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains, etc. are equipped.
• An auxiliary-sup ported run-flat tire
is equipped.
• If a window tint that affects the
radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the
wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the speci-
fied level.
• If tires not equipped with tire pres- sure warning valv es and transmit-
ters are used.
• If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure
warning computer.
●Performance may be affected in
the following situations.
• Near a TV tower, electric power
plant, gas station, radio station,
large display, airport or other facil-
ity that generates strong radio
waves or electrical noise.
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication
device.
●When the vehicle is parked, the
time taken for the warning to start
or go off could be extended.
●When tire inflation pressure
declines rapidly for example when
a tire has burst, the warning may
not function.

Maintenance and care
The recommended cold tire
inflation pressure and tire size
are displayed on the tire and
loading information label.
( P.531)
Tire valve Tire pressure gauge
1 Remove the tire valve cap.
2 Press the tip of the tire pres-
sure gauge onto the tire
valve.
3 Read the pressure using the
gauge gradations.
4 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.
5 After completing the tire infla-
tion pressure measurement
and adjustment, apply soapy
water to the valve and check
for leakage.
6 Put the tire valve cap back
on.
■Tire inflation pressure check
interval
You should check tire inflation pres-
sure 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.
