Maintenance and care
■
Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, observe the following 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.
■ After recharging/reconnect ing the 12-volt battery
In some cases, the hybrid system may not start. Follow one or both of the
following procedures:
● After opening and closing the driver’s door, wait 10 seconds then attempt
to start the hybrid system. (If the system does not start first time, repeat
the procedure.)
● With the shift lever in P and the “POWER” switch OFF, open and close
the driver’s door, then attempt to start the hybrid system.
If the system will not start even after multiple attempts at both methods, con-
tact your Toyota dealer.

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 the 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 not sufficient ventilation.
■ How to recharge the 12-volt battery
Only perform a slow charge (5 A or less). The 12-volt battery may explode if
charged at a quicker rate.
■ 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. Follow with milk of magnesia,
beaten raw egg or vegetable oil. Get emergency medical attention immedi-
ately.

Maintenance and care
CAUTION
■
When replacing the 12-volt battery
Use a 12-volt battery designed for the CAMRY HYBRID. Failure to do so
may cause gas (hydrogen) to enter the passenger compartment, causing a
fire or explosion.
For replacement of the 12-volt battery, contact your Toyota dealer.
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 sched-
ules and treadwear.
■Checking tires
New tread
Treadwear indicator
Worn tread
The location of treadwear
indicators is shown by the
“TWI” or “ ” marks, etc.,
molded on the sidewall of
each tire.
Check spare tire condition
and inflation pressure if not
rotated.
■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.
■The tire pressure warning system
Your Toyota is equipped with a ti re pressure warning system that
uses tire pressure warning valves and transmitters to detect low
tire inflation pressure before serious problems arise. (→P. 351)
The compact spare tire is not equipped with a tire pressure warn-
ing valve and transmitter.

Maintenance and care
Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new tire pressure warning valve and transmitter ID codes
must be registered in the tire pr essure warning computer and tire
pressure warning system must be initialized. Have tire pressure
warning valve and transmitter ID codes registered by your Toyota
dealer. ( →P. 306)
Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized when the
tire inflation pressure is changed (such as when changing
traveling speed).
When the tire pressure warning syst em is initialized, the current tire
pressure is set as the pressure benchmark.
■ How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn off the hybrid system.
Initialization is not performed while the vehicle is moving.
Adjust the tire pressure to the specified pressure. (→P. 4 0 4 )
Make sure to adjust the tire pressure to the specified cold tire
inflation pressure level. The tire pressure warning system will
operate based on this pressure level.
Turn the “POWER” switch to ON mode.

Open the glove box, and press
and hold the tire pressure warn-
ing reset switch until the tire
pressure warning light blinks
slowly three times.
The tire pressure warning light
will flash 3 times to indicate that
initialization has started.
Wait for a few minutes with the ON mode, and then turn the
“POWER” switch OFF.
Registering ID codesThe tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to regi ster the ID code of tire pressure
warning valve and transmitter. Have the ID code registered by your
Toyota dealer.

Maintenance and care
■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 or bulges indicating internal damage
●A tire goes flat repeatedly or cann
ot be properly repaired due to the
size or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pressure warni ng system will not work properly. After
about 20 minutes, the tire pressure warning light comes 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 technician even
if they have seldom or never been 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.
■If you press the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire inflation pressure to the specified
level and initialize the tire pressure warning system again.
