WARNING
■When fixing the flat tire
●Stop your vehicle in a safe and flat area.
●Do not touch the wheels or the area around the brakes immediately after the vehicle
has been driven. After the vehicle has been driven, the wheels and the area around the brakes may be
extremely hot. Touching these areas with hands, feet or other body parts may result in
burns.
●Connect the valve and hose securely wi th the tire installed on the vehicle.
●If the hose is not properly connected to the valve, air leakage may occur or sealant
may be sprayed out.
●If the hose comes off the valve while inflating the tire, there is a risk that the hose will
move abruptly due to air pressure.
●After inflation of the tire ha s completed, the sealant may splatter when the hose is dis- connected or some air is let out of the tire.
●Follow the operation procedure to repair the tire. If the procedure is not followed, the
sealant may spray out.
●Keep back from the tire while it is being re paired, as there is a chance of it bursting
while the repair operation is being performed. If you notice any cracks or deforma-
tion of the tire, turn off the compressor sw itch and stop the repair operation immedi- ately.
●The kit may overheat if operated for a long period of time. Do not operate the com-
pressor continuously for more than 10 minutes.
●Parts of the kit become hot during operatio n. Be careful handling the kit during and
after operation.
●Do not attach the vehicle speed warning stic ker to an area other than the one indi- cated. If the sticker is attached to an area where an SRS airbag is located, such as the
pad of the steering wheel, it may prevent the SRS air bag from operating properly.
■Driving to spread the liquid sealant evenly
●Drive the vehicle carefully at a low speed. Be especially careful when turning and cor-
nering.
●If the vehicle does not drive straight or you feel a pull through the steering wheel, stop the vehicle and check the following:
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If tire infl ation pressure is 130 kPa (1.3 kgf/cm2 or bar, 19 psi) or below, this may indi cate severe tire damage.

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 does not come
on, contact any authorized Lexus retailer or Lexus 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.
Once the hybrid system starts, have the vehicle inspected at any authorized
Lexus retailer or Lexus authorized repair er, 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 componen ts when the vehicle is running at a low
speed for an extended period , such as in heavy traffic.
■Charging the 12-volt battery
The electricity stored in the 12-volt battery w ill discharge gradually even when the vehicle
is not in use, due to natural discharge and the draining effects of certain electrical appli-
ances. If the vehicle is left for a long time, the 12-volt battery may discharge, and the hybrid system may be unable to start. (The 12-volt battery recharges automatically while
the hybrid system is operating.)
■When recharging or repl acing the 12-volt battery
●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 wireless 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 battery is reconnected, the system will retu rn to the mode it was in before the 12-volt battery was
discharged. Before disconnecting the 12-vol t battery, turn the power switch off.
If you are unsure what mode the power switch was in before the 12-volt battery dis- charged, be especially careful when reconnecting the 12-volt battery.

Start the hybrid system and check if “Hybrid System Overheated Reduced
Output Power” is shown on the multi-information display.
If the message does not disappear:
Stop the hybrid system and contact an y authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer.
If the message is not displayed:
Have the vehicle inspected at the nearest authorized Lexus retailer or
Lexus 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 “READY” indicator is off.
When the hybrid system operating, the gasoline engine may automatically start, or
the cooling fan may suddenly operate even if the gasoline engine stops. Do not touch or approach rotating parts such as the be lt and fan, which may lead to fingers or
clothing (especially a tie, a scarf or a mu ffler) getting caught, resulting in serious
injury.

●Do not loosen the c oolant reservoir caps or
water filler cap while th e hybrid system and
radiator are hot. High temperature steam or coolant could
spray out.
