WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents. Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
●Use tires of the specified size.
●Maintain the recommended level of air pressure.
●Do not drive at speeds in excess of the speed limit or the speed limit specified for the snow tires being
used.
●Use snow tires on all, not just some
wheels.
■Driving with tire chains
Observe the following precautions to reduce the risk of accidents.Failure to do so may result in the vehi-
cle being unable to be driven safely, and may cause death or serious injury.
●Do not drive in excess of the speed limit specified for the tire chains being used, or 50 km/h (30 mph),
whichever is lower.
●Avoid driving on bumpy road sur-
faces or over potholes.
●Avoid sudden acceleration, abrupt
steering, sudden braking and shift- ing operations that cause sudden regenerative braking.
●Slow down sufficiently before enter-ing a curve to ensure that vehicle

For details, consult with at any autho-
rized Toyota retailer or Toyota autho- rized repairer, or any reliable repairer as soon as possible.
WARNING
■When removing the 12-volt bat-tery terminals
Always remove the negative (-) termi-
nal first. If the positive (+) terminal contacts any metal in the surrounding area when the positive (+) terminal is
removed, a spark may occur, leading to a fire in addition to electrical shocks and death or serious injury.
■Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-mable gas that may be emitted from
the 12-volt battery:
●Make sure each jumper cable is connected to the correct terminal
and that it is not unintentionally in contact with any other than the intended terminal.
●Do not allow the other end of the jumper cable connected to the “+”
terminal to come into contact with any other parts or metal surfaces in the area, such as brackets or
unpainted metal.
●Do not allow the + and - clamps of
the jumper cables to come into con- tact with each other.
●Do not smoke, use matches, ciga-rette lighters or allow open flame near the 12-volt battery.
■12-volt battery precautions
The 12-volt battery contains poison- ous and corrosive acidic electrolyte,
while related parts contain lead and lead compounds. Observe the follow-ing precautions when handling the
12-volt battery:
●When working with the 12-volt bat- tery, always wear safety glasses
and take care not to allow any bat- tery fluids (acid) to come into con-tact with skin, clothing or the vehicle
body.
●Do not lean over the 12-volt battery.
●In the event that battery fluid (acid) comes into contact with the skin or
eyes, immediately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention can be received.
●Always wash your hands after han-dling the 12-volt battery and other
battery-related parts.
●Do not allow children near the 12-
volt battery.
■When replacing the 12-volt bat-
tery
●When the vent plug is close to the hold down clamp, the battery fluid
(acid) may leak.
●For information regarding battery
replacement, contact any autho- rized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
NOTICE
■When handling jumper cables
When connecting the jumper cables,
ensure that they do not become entangled in the cooling fan.
