Maintenance and care
■
After recharging/reconnecting the battery (vehicles with a smar t key
system)
● Unlocking the doors using the smart key system may not be possi ble
immediately after reconnecting the battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the do ors.
● Start the engine with the “ENGINE START STOP” switch in ACCES-
SORY mode. The engine may not start with the “ENGINE START STOP ”
switch turned off. However, the engine will operate normally from the sec-
ond attempt.
● The “ENGINE START STOP” switch mode is recorded by the vehicle. If
the battery is reconnected, the vehicle will return the “ENGINE START
STOP” switch mode to the status it was in before the battery was discon-
nected. Make sure to turn off the engine before disconnect the battery.
Take extra care when connecting the battery if the “ENGINE STAR T
STOP” switch mode prior to discharge is unknown.
If the engine will not start even after multiple attempts, cont act your Toyota
dealer.

WARNING
■Chemicals in the battery
A 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 precautions while working on or near the
battery:
● Do not cause sparks by touching the battery terminals with tool s.
● Do not smoke or light a match near the battery.
● Avoid contact with eyes, skin and clothes.
● Never inhale or swallow electrolyte.
● 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 ba ttery in a
garage or closed room where there is not sufficient ventilation.
■ Emergency measures regarding electrolyte
●If electrolyte gets in your eyes
Flush your eyes with clean water for at least 15 minutes and get immedi-
ate medical attention. If possible, continue to apply water with a sponge or
cloth while traveling to the nearest medical facility.
● If electrolyte gets on your skin
Wash the affected area thoroughly. If you feel pain or burning, get medical
attention immediately.
● If electrolyte gets on your clothes
It can soak through clothing on to your skin. Immediately take off the cloth-
ing and follow the procedure above if necessary.
● If you accidentally swallow electrolyte
Drink a large quantity of water or milk. Get emergency medical attention
immediately.

Maintenance and care
Washer fluid
If the washer fluid level is at
“LOW”, add washer fluid.
NOTICE
■When recharging the battery
Never recharge the battery while the engine is running. Also, b e sure all
accessories are turned off.
■ When adding distilled water
Avoid overfilling. Water spilled during battery recharging may cause corro-
sion.
■ Using the gauge
The washer fluid level can be checked by
observing the position of the level on the
liquid-covered holes in the gauge.
If the level falls below the second hole
from the bottom (the “LOW” position),
refill the washer fluid.

WARNING
■When adding washer fluid
Do not add washer fluid when the engine is hot or running, as washer fluid
contains alcohol and may catch fire if spilled on the engine et c.
NOTICE
■Washer fluid
Do not use soapy water or engine antifreeze instead of washer f luid.
Doing so may cause streaking on the vehicle’s painted surfaces, as well as
damaging the pump leading to problems of the washer fluid not s praying.
■ Diluting washer fluid
Dilute washer fluid with water as necessary.
Refer to the freezing temperatures listed on the label of the w asher fluid bot-
tle.

Maintenance and care
Tires
Replace or rotate tires in accordance with maintenance sched-
ules and treadwear.
■Checking tires
Check if the treadwear indicators are showing on the tires. Als o
check the tires for uneven wear, such as excessive wear on one
side of the tread.
Check the spare tire condition and pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators is shown by a “TWI” or “ ” mark,
etc., molded into the sidewall of each tire.
Replace the tires if the treadwear indicators are showing on a tire.
■Tire rotation
Rotate the tires in the order
shown.
To equalize tire wear and
extend tire life, Toyota recom-
mends that tire rotation is
carried out at the same inter-
val as tire inspection.

Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves an d
transmitters must a lso be installed.
When new tire pressure warning valves and transmitters are
installed, new tire pressure warning valve and transmitter ID c odes
must be registered in the tire pressure warning computer and ti re
pressure warning system must be i nitialized. Have tire pressure
warning valve and transmitter ID codes registered by your Toyot a
dealer. ( P. 346)
Registering ID codes
The tire pressure warning valve and transmitter is equipped wit h a
unique ID code. When replacing a tire pressure warning valve an d
transmitter, it is necessary to register the ID code. Have the ID code
registered by your Toyota dealer.
■ The tire pressure warning system
Your Toyota is equipped with a tire pressure warning system tha t
uses tire pressure warning valves and transmitters to detect lo w
tire inflation pressure befor e serious problems arise.
(  P. 3 9 9 )

Maintenance and care
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as c
uts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the
size or location of a cut or other damage
If you are not sure, consul t with your Toyota dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitt er is not
registered, the tire pressure w arning system will not work prop erly. After
driving for about 20 minutes, t he tire pressure warning light c omes on
after blinking for 1 minute to indicate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified techni cian even
if they have seldom or never b een used or damage is not obvious.
■If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■Low profile tires
Generally, low profile tires will wear more rapidly and tire gr ip perfor-
mance will be reduced on snowy and /or icy roads when compared to
standard tires. Be sure to use snow tires or tire chains on sno wy and/or
icy roads and drive carefully at a speed appropriate for road a nd weather
conditions.

348 4-3. Do-it-yourself maintenance
■Maximum load of tire
Check that the maximum load of the replacement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAWR) of either the front axle or the
rear axle, whichever is greater.
■Tire types
1 Summer tires
Summer tires are high-speed performance tires best suited to hi ghway
driving under dry conditions. Since summer tires do not have th e same
traction performance as snow tires, summer tires are inadequate for
driving on snow-covered or icy roads. For driving on snow-cover ed
roads or icy roads, the use of snow tires is recommended. When
installing snow tires, be sure to replace all four tires.
2 All season tires
All season tires are designed to provide better traction in sno w and to
be adequate for driving in most winter conditions, as well as f or use
year round. All season tires, however, do not have adequate tra ction
performance compared with snow tires in heavy or loose snow. Al so,
all season tires fall short in acceleration and handling perfor mance
compared with summer tires in highway driving.
3Snow tires For driving on snow-covered roads or icy roads, we recommend us ing
snow tires. If you need snow tires, select tires of the same si ze, con-
struction and load capacity as th e originally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tir es without
first checking local regulations for possible restriction. Snow tires
should be installed on all wheels. ( P. 261)
For the GAWR, see the Certification
Label. For the maximum load of the
tire, see the load limit at maximum cold
tire inflation pressure mentioned on the
sidewall of the tire. ( P. 4 7 4 )

Maintenance and care
■Initializing the tire p
ressure warning system
Initialize the system with the ti re inflation pressure adjusted to the speci-
fied level.
■Routine tire infla tion 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.

smart key system)
