■When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press any
buttons on the electronic key while inside the aircraft cabin. If you are carry-ing an electronic key in your bag etc.,
ensure that the buttons are not likely to be pressed accidentally. Pressing a but-ton may cause the electronic key to emit
radio waves that could interfere with the operation of the aircraft.
■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
●If the battery becomes low, an alarm will sound in the cabin and a message will be displayed on the multi-informa-
tion display when the hybrid system
stops.
●To reduce key battery depletion when
the electronic key is to not be used for long periods of time, set the electronic key to the battery-saving mode.
( P.254)
●As the electronic key always receives
radio waves, the battery will become depleted even if the electronic key is not used. The following symptoms
indicate that the electronic key battery may be depleted. Replace the battery when necessary.
• The smart entry & start system or the wireless remote control does not oper-ate.
• The detection area becomes smaller. • The LED indicator on the key surface does not turn on.
You can replace the battery by yourself
( P.511). However, as there is a dan-
ger that the electronic key may be dam-
aged, it is recommended that
replacement is carried out by any autho-
rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.
●To avoid serious deterioration, do not leave the electronic key within 1 m (3
ft.) of the following electrical appli- ances that produce a magnetic field:•TVs
• Personal computers • Cellular phones, cordless phones and battery chargers
•Table lamps • Induction cookers
●If the electronic key is near the vehicle for longer than necessary, even if the smart entry & start system is not oper-
ated, the key battery may become depleted faster than normal.
■If a message regarding the state of the electronic key or power switch
mode, etc. is shown
To prevent trapping the electronic key inside the vehicle, leaving the vehicle
carrying the electronic key on your per- son without turning the power switch to

5-6.Driving tips
Use fluids that are appropriate to
the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Power control unit coolant
• Washer fluid
 Have a service technician
inspect the condition of the 12-
volt battery.
 Have the vehicle fitted with four
snow tires or purchase a set of
tire chains for the front tires.
Ensure that all tires are the same size
and brand, and that chains match the
size of the tires.*
*: Tire chains cannot be mounted on
vehicles with 235/55R19 tires.
Winter driving tips
Carry out the necessary prepa-
rations and inspections before
driving the vehicle in winter.
Always drive the vehicle in a
manner appropriate to the pre-
vailing weather conditions.
Pre-winter preparations
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 (except
235/55R19 tires)
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 engine braking.
●Slow down sufficiently before enter-ing a curve to ensure that vehicle control is maintained.
●Do not use LTA (Lane Tracing Assist) system (if equipped).
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer or legitimate tire retailers.
This is because the removal and attachment of snow tires affects the operation of the tire pressure warning
valves and transmitters.

5768-2. Steps to take in an emergency
operate properly ( P.572). This is not
a malfunction, as the hybrid system will start normally on the second attempt.
●The power switch mode is memorized by the vehicle. When the 12-volt bat-
tery is reconnected, the system will return to the mode it was in before the 12-volt battery was discharged.
Before disconnecting the 12-volt bat- tery, turn the power switch off.If you are unsure what mode the
power switch was in before the 12-volt battery discharged, be especially careful when reconnecting the 12-volt
battery.
■When replacing the 12-volt battery
●Use a 12-volt battery that conforms to
European regulations.
●Use a 12-volt battery that the case
size is same as the previous one (LN2), 20 hours rate capacity (20HR) is equivalent (55Ah) or greater, and
performance rating (CCA) is equiva- lent (345A) or greater.• If the sizes differ, the 12-volt battery
cannot be properly secured. • If the 20 hour rate capacity is low, even if the time period where the vehi-
cle is not used is a short time, the 12- volt battery may discharge and hybrid system may not be able to start.
●Use a ventilation type calcium battery
●Use a 12-volt battery with a handle. If a 12-volt battery without a handle is used, removal is more difficult.
●When removing the 12-volt battery:  P.486
●After replacing, firmly attach the fol- lowing items to the exhaust hole of the
12-volt battery. • Use the exhaust hose that was attached to the 12-volt battery before
replacing and confirm that it is firmly connected to the hole section of the vehicle.
• Use the exhaust hole plug included with the new 12-volt battery or the one installed on the battery prior to the
replacement. (Depending on the new
12-volt battery installed, the exhaust hole may be plugged.)
For details, consult any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

●The terminals can be connected to the body side when the negative terminal
of the 12-volt battery is disconnected, as shown in the illustration.
WARNING
■When removing the battery ter-minals
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.

When trouble arises
WARNING
■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 comes
into contact with the skin or eyes, immediately wash the affected area with water and seek medical atten-
tion. 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 support, terminals, and other battery-related
parts.
●Do not allow children near the 12-
volt battery.
■After recharging the 12-volt bat-
tery
Have the 12-volt battery inspected at any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer as soon as possible.If the 12-volt battery is deteriorating,
continued use may cause the 12-volt battery to emit a malodorous gas, which may be detrimental to the
health of passengers.
■When replacing the 12-volt bat-
tery
●For information regarding 12-volt battery replacement, contact any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●After replacing, securely attach the exhaust hose and exhaust hole
plug to the exhaust hole of the replaced 12-volt battery. If not prop-erly installed, gases (hydrogen)
may leak into the vehicle interior, and there is the possible danger of the gas igniting and exploding.
