WARNING
QWhen using the compact spare tire
ORemember that the compact spare tire provided is specifically designed for use with your vehicle.
Do not use your compact spare tire on another vehicle.
ODo not use more than one compact spare tire simultaneously.
OReplace the compact spare tire with a standard tire as soon as possible.
OAvoid sudden acceleration, abrupt steering, sudden braking and shift-ing operations that cause sudden
engine braking.
QWhen the compact spare tire is
attached
The vehicle speed may not be cor- rectly detected, and the following sys-
tems may not operate correctly:
• ABS & Brake assist
• VSC/Trailer Sway Control
•TRC
• Cruise control (if equipped)
• Dynamic radar cruise control with full-speed range (if equipped)
• PCS (Pre-Collision System) (if equipped)
• EPS
• LTA (Lane Tracing Assist) (if
equipped)
• Tire pressure warning system
• AHB (Automatic High Beam) (if equipped)

QSpeed limit when using the com-pact spare tire
Do not drive at speeds in excess of 80
km/h (50 mph) when a compact spare tire is installed on the vehicle.
The compact spare tire is not
designed for driving at high speeds. Failure to observe this precaution may lead to an accident causing
death or serious injury.
QAfter using the tools and jack
Before driving, make sure all the tools and jack are securely in place in their storage location to reduce the possi-
bility of personal injury during a colli- sion or sudden braking.
NOTICE
QBe careful when driving over
bumps with the compact spare tire installed on the vehicle
The vehicle height may become lower
when driving with the compact spare tire compared to when driving with standard tires. Be careful when driv-
ing over uneven road surfaces.

minutes to recharge the 12-volt
battery of your vehicle.
6 Open and close any of the doors
of your vehicle with the power
switch off.
7 Maintain the engine speed of
the second vehicle and start the
hybrid system of your vehicle by
turning the power switch to ON.
8 Make sure the “READY” indica-
tor comes on. If the indicator
light does not come on, contact
any authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer.
9 Once the hybrid system has
started, remove the jumper
cables in the exact reverse
order from which they were con-
nected.
10 Close the exclusive jump start-
ing terminal cover, and reinstall
the fuse box cover to its original
position.
Once the hybrid system starts,
have the vehicle inspected at any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer as soon as possible.
QStarting the hybrid system when
the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
QTo prevent 12-volt battery dis-
charge
OTurn off the headlights and the audio
system while the hybrid system is off.
OTurn off any unnecessary electrical
components when the vehicle is run- ning at a low speed for an extended period, such as in heavy traffic.
QWhen the 12-volt battery is
removed or discharged
OInformation stored in the ECU is
cleared. When the 12-volt battery is depleted, have the vehicle inspected at any authorized Toyota retailer or
Toyota authorized repairer, or any reli- able repairer.
OSome systems may require initializa-tion. ( P.582)
QWhen removing the 12-volt battery terminals
When the 12-volt battery terminals are removed, the information stored in the ECU is cleared. Before removing the 12-
volt battery terminals, contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
QCharging the 12-volt battery
The electricity stored in the 12-volt bat- tery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the draining effects of certain electrical appliances. If the vehi-
cle is left for a long time, the 12-volt bat- tery may discharge, and the hybrid system may be unable to start. (The 12-
volt battery recharges automatically while the hybrid system is operating.)
QWhen recharging or replacing the 12-volt battery
OIn some cases, it may not be possible to unlock the doors using the smart
entry & start system when the 12-volt battery is discharged. Use the wire-less remote control or the mechanical
key to lock or unlock the doors.
OThe hybrid system may not start on
the first attempt after reinstalling the 12-volt battery. In that case, start the hybrid system in the same manner as
when the electronic key does not operate properly ( P.545). This is not

volt battery from another vehicle in an emergency. It cannot be used to jump start another vehicle.
If your vehicle overheats
The following may indicate that
your vehicle is overheating.
 The high coolant temperature
warning light ( P.168) comes
on or flashes, or a loss of
hybrid system power is experi-
enced. (For example, the vehi-
cle speed does not increase.)
 “Engine Coolant Temp High

3After the hybrid system has
cooled down sufficiently, inspect
the hoses and radiator core
(radiator) for any leaks.
Radiator
Cooling fan
If a large amount of coolant leaks, immediately contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
4 The coolant level is satisfactory
if it is between the “FULL” and
“LOW” lines on the reservoir.
Reservoir
“FULL” line
“LOW” line
5 Add coolant if necessary.
Water can be used in an emergency if
engine coolant is unavailable. If water was added in an emergency,
have the vehicle inspected at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer as soon as possible.
6 Start the hybrid system and turn
the air conditioning system on to
check that the radiator cooling
fan operates and to check for
coolant leaks from the radiator
or hoses.
The fan operates when the air condi- tioning system is turned on immediately
after a cold start. Confirm that the fan is operating by checking the fan sound and air flow. If it is difficult to check
these, adjust the temperature control switch to “LO” and turn the “A/C” switch ON and OFF. After this, turn the air
conditioning system on and off repeat- edly. (The fan may not operate in freez-ing temperatures.)
7 If the fan is not operating:
Stop the hybrid system immedi-
ately and contact any authorized
Toyota retailer or Toyota autho-
rized repairer, or any reliable
repairer.
If the fan is operating:
Have the vehicle inspected at
the nearest authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.

WARNING
QWhen inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
OIf steam is seen coming from under
the hood, do not open the hood until the steam has subsided. The engine compartment may be very
hot.
OAfter the hybrid system has been
turned off, check that the “READY” indicator is off.When the hybrid system is operat-
ing, the gasoline engine may auto- matically start, or the cooling fan may suddenly operate even if the
gasoline engine stops. Do not touch or approach rotating parts such as the fan, which may lead to fingers
or clothing (especially a tie, a scarf or a muffler) getting caught, result-ing in serious injury.
ODo not loosen the coolant reservoir cap while the hybrid system and
radiator are hot. High temperature steam or coolant could spray out.
NOTICE
QWhen adding engine/power con-trol unit coolant
Add coolant slowly after the hybrid system has cooled down sufficiently. Adding cool coolant to a hot hybrid
system too quickly can cause dam- age to the hybrid system.
QTo prevent damage to the cool-ing system
Observe the following precautions:
OAvoid contaminating the coolant with foreign matter (such as sand or dust, etc.).
ODo not use any coolant additive.
