326 4-1. Maintenance and care
NOTICE
■Cleaning detergents
Do not use organic substances such as benzene or gasoline, acidic or alka-
line solutions, dye, bleach or other detergent. Doing so may discolor the
vehicle interior or cause streaks or damage to painted surfaces.
■ Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration o\
f
leather surfaces.
●Remove any dust or dirt on leather surfaces immediately.
● Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
● Do not place items made of vinyl, plastic, or that contain wax, on the
upholstery, as they may stick to the leather surface if the vehicle interior
heats up significantly.
■ Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components under the floor of the vehicle, and
may also cause the body to rust.
■ Cleaning the inside of the rear window
●Do not use glass cleaner to clean the rear window, as this may cause
damage to the rear window defogger heater wires or antenna. Use a cloth
dampened with lukewarm water to gently wipe the window clean. Wipe the
window in strokes running parallel to the heater wires or antenna.
● Be careful not to scratch or damage the heater wires or antenna.

■ After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacing. ( P. 383)
● If the replaced fuse blows again, have the vehicle inspected by your
Toyota dealer.
■ If there is an overload in the circuits
The fuses are designed to blow before the entire wiring harness is damaged.

5-2. Steps to take in an emergency
■
Avoiding a discharged 12-volt battery
●Turn off the headlights and the audio system while the hybrid system is
turned off.
● Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic, etc.
■ When the 12-volt battery is removed or discharged
The hybrid system may not start. ( P. 349)
■ Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
Start the engine of the seco nd vehicle. Increase the gaso-
line engine speed slightly and maintain at that level for
approximately 5 minutes to recharge the 12-volt battery of
your vehicle.
Open and close any of the doors with the “POWER” switch
OFF.
Maintain the engine speed of the second vehicle and turn
the “POWER” switch to ON mode, then start the hybrid sys-
tem.
Make sure the “READY” indicator comes on. If the indicator
does not comes on, contact your Toyota dealer.
Once the hybrid system has started, remove the jumper
cables in the exact reverse order in which they were con-
nected.
Once the hybrid system starts, have the vehicle checked at your
Toyota dealer as soon as possible.STEP3
