WARNING
■When using the compact spare tire 
● Remember that the spare tire provided is specifically designed for use with 
your vehicle. Do not use your spare tire on another vehicle. 
● Do not use more than one compact spare tire simultaneously. 
● Replace the spare tire with a standard tire as soon as possible. 
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting 
operations that cause sudden engine braking. 
■ When the compact spare tire is attached 
The vehicle speed may not be correctly detected, and the following systems 
may not operate correctly: 
■ Speed limit when using the compact 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. 
■ After 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 possibility of personal injury during a collision
or sudden braking.

When trouble arises
Start the engine of the second vehicle. Increase the engine speed 
slightly and maintain at that level for approximately 5 minutes to 
recharge the 12-volt battery of your vehicle. 
Maintain the engine speed of the second vehicle and start the 
hybrid system of your vehicle by turning the power switch to ON 
mode. 
Make sure the “READY” indicator comes on. If the indicator light 
does not come on, contact any authorized Toyota retailer or Toyota 
authorized repairer, or any reliable repairer. 
Once the hybrid system has started, remove the jumper cables in 
the exact reverse order from which they were connected. 
Close the exclusive jump starting terminal cover, and reinstall the 
fuse box cover to its original position.
When installing, first hook the fuse box cover onto the two rear tabs.
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.
■ Starting the hybrid system when the 12-volt battery is discharged 
The hybrid system cannot be started by push-starting. 
■ To prevent 12-volt battery discharge 
● Turn off the headlights and the audio system while the hybrid system is off. 
● Turn off any unnecessary electrical components when the vehicle is running 
at a low speed for an extended period, such as in heavy traffic. 
■ When the 12-volt battery is removed or discharged 
● In 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. 
● The hybrid system may not start on the first attempt after the 12-volt battery 
has recharged but will start normally after the second attempt. This is not a
malfunction. 
● 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 battery, 
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 recon-
necting the 12-volt battery.

When trouble arises
After stopping the hybrid system and waiting for 5 minutes or 
more, start the hybrid system and check for the instrument clus- 
ter or multi-information display. 
If the hybrid system overheat warning light does not turn off or 
the message does not disappear:  
Stop the hybrid system and contact any authorized Toyota 
retailer or Toyota authorized repairer, or any reliable repairer. 
If the hybrid system overheat warning light does not come on or 
the message is not displayed:  
The hybrid system temperature has dropped and the vehicle may 
be driven normally.
However, if the warning light comes on again frequently or the message 
appears again frequently, contact any authorized Toyota retailer or 
Toyota authorized repairer, or any reliable repairer.
WARNING
■ When inspecting under the hood of your vehicle 
Observe the following precautions. 
Failure to do so may result in serious injury such as burns. 
● If 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. 
● After the hybrid system has been turned off, check that the indicator on the 
power switch and the “READY” indicator are off.  
When the hybrid system is operating, the gasoline engine may automati- 
cally 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, resulting in serious injury. 
● Do not loosen the coolant reservoir cap while the hybrid system and radia- 
tor are hot. 
High temperature steam or coolant could spray out.

NOTICE
■When adding engine/power control 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 damage to 
the hybrid system. 
■ To prevent damage to the cooling system 
Observe the following precautions: 
● Avoid contaminating the coolant with foreign matter (such as sand or dust 
etc.). 
● Do not use any coolant additive.
