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 br aking 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.

8-2. Steps to take in an emergency
When trouble arises
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 batt ery 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.508
●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 batte ry is disconnected,
as shown in the illustration.
WARNING
■When removing the battery ter -
minals
Always remove the negative (-) termi-
nal first. If the posi tive (+) terminal
contacts any metal in the surrounding area when the positiv e (+) terminal is
removed, a spark m ay occur, leading
to a fire in addition to electrical shocks and death or serious injury.
