Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, observe the following precautions before
recharging:
If recharging with the 12-volt battery installed on the vehicle, be sure to
disconnect the ground cable.
Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the 12-volt battery.
When disconnecting the 12-volt battery terminals
Always disconnect the negative (-) terminal first.
After recharging/reconnecting the 12-volt battery
Unlocking the doors using the smart entry & start system may not be
possible immediately after reconnecting the 12-volt battery. If this hap-
pens, use the wireless remote control or the mechanical key to lock/
unlock the doors.
Vehicles with an electronic key: Start the hybrid system with the
“POWER” switch in ACCESSORY mode. The hybrid system may not
start with the “POWER” switch turned off. However, the hybrid system will
operate normally from the second attempt.
Vehicles with an electronic key: The “POWER” switch mode is recorded
by the vehicle. If the 12-volt battery is reconnected, the vehicle will return
the “POWER” switch mode to the status it was in before the 12-volt bat-
tery was disconnected. Make sure to turn off the power before discon-
nect the 12-volt battery. Take extra care when connecting the 12-volt
battery if the “POWER” switch mode prior to discharge is unknown.
If the system will not start even after multiple attempts, contact any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.

CAUTION
Chemicals in the 12-volt battery
The 12-volt 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 12-volt battery:
Do not cause sparks by touching the 12-volt battery terminals with tools.
Do not smoke or light a match near the 12-volt battery.
Avoid contact with eyes, skin and clothes.
Never inhale or swallow electrolyte.
Wear protective safety glasses when working near the 12-volt battery.
Keep children away from 12-volt battery.
Where to safely charge the 12-volt battery
Always charge the 12-volt battery in an open area. Do not charge the 12-volt
battery in a garage or closed room where there is insufficient ventilation.
When disconnecting the 12-volt battery terminals
Always disconnect the negative (-) terminal first. If the positive (+) terminal is
disconnected first and touches a surrounding metal surface sparks will be
produced, possibly starting a fire. It could also result in an electric shock or
serious injury.
How to recharge the 12-volt battery
Only perform a slow charge (3.5 A or less). The 12-volt battery may explode
if charged at a quicker rate.

CAUTION
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.
When replacing the 12-volt battery
Use a 12-volt battery designed for this vehicle. Failure to do so may cause
gas (hydrogen) to enter the passenger compartment, causing a fire or explo-
sion.
For replacement of the 12-volt battery, contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
NOTICE
When recharging the 12-volt battery
Never recharge the 12-volt battery while the hybrid system is operating.
Also, be sure all accessories are turned off.

Tires
Replace or rotate tires in accordance with maintenance schedules
and treadwear.
Checking tires
New tread
Treadwear indicator
Worn tread
The location of treadwear indi-
cators is shown by the “TWI” or
“” marks, etc., molded on the
sidewall of each tire.
Check spare tire condition and
pressure if not rotated.
Tire rotation
Vehicles with a spare tire of different wheel type from the
installed tires or an emergency tire puncture repair kit
Rotate the tires in the order
shown.
To equalize tire wear and help
extend tire life, Toyota recom-
mends that tire rotation is car-
ried out approximately every
10000 km (6000 miles).

When to replace your vehicle’s tires
Tires should be replaced if:
You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric, and 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, consult with any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.
Tire life
Any tire over 6 years old must be checked by a qualified technician even if it
has seldom or never been used or damage is not obvious.
Low profile tires (vehicles with 195/50R16 tires)
Generally, low profile tires will wear more rapidly and tire grip performance
will be reduced on snowy and/or icy roads when compared to standard tires.
Be sure to use snow tires or tire chains on snowy and/or icy roads and drive
carefully at a speed appropriate for road and weather conditions.
If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
Vehicles with a spare tire of the same wheel type as the
installed tires
Rotate the tires in the order
shown.
To equalize tire wear and help
extend tire life, Toyota recom-
mends that tire rotation is car-
ried out approximately every
10000 km (6000 miles).

CAUTION
When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as dan-
gerous handling characteristics, which may lead to an accident resulting in
death or serious injury.
Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
Do not use tire sizes other than those recommended by Toyota.
Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
Do not mix summer, all season and snow tires.
Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
Vehicles with a compact spare tire: Do not tow if your vehicle has a com-
pact spare tire installed.
