WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When towing the vehicle
■ While towing
● When towing using cables or chains, avoid sudden starts, etc., which
place excessive stress on the towing eyelets, cables or chains. The towing
eyelets, cables or chains may become damaged, broken debris may hit
people, and cause serious damage.
● Do not turn the power switch off.
There is a possibility that the steering wheel is locked and ca nnot be oper-
ated.
■ Installing towing eyelets to the vehicle
Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing.
Be sure to transport the vehicle with the
front wheels raised or with all four wheels
raised off the ground. If the vehicle is
towed with the front wheels contacting
the ground, the drivetrain and related
parts may be damaged or electricity gen-
erated by the operation of the motor may
cause a fire to occur depending on the
nature of the damage or malfunction.

When trouble arises
NOTICE
■Towing with a sling-type truck
■ To prevent damage to the vehicle when towing using a wheel-lift type
truck
● Do not tow the vehicle from the rear when the power switch is off. The
steering lock mechanism is not strong enough to hold the front wheels
straight.
● When raising the vehicle, ensure adequate ground clearance for towing at
the opposite end of the raised vehicle. Without adequate cleara nce, the
vehicle could be damaged while being towed.
■ To prevent damage to the vehicle when towing with a sling-type truck
Do not tow with a sling-type tr uck, either from the front or rear.
■ To prevent damage to the vehicle during emergency towing
Do not secure cables or chains to the suspension components

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 arou nd the
brakes may be extremely hot. Touching these areas with hands, f eet or
other body parts may result in burns.
● To avoid risk of burst or severe leakage, do not drop or damage the bottle.
Visually inspect the bottle before use. Do not use a bottle wit h shock,
crack, scratch, leakage or any other damage. In such case, imme diately
replace.
● Connect the valve and hose securely with the wheel installed to the vehi-
cle. If the hose is not properly connected to the valve, air le akage may
occur and 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 has completed, the sealant may splatter when the
hose is disconnected or some air is let out of the tire.
● Follow the operation procedure to repair the tire. If the procedures not fol-
lowed, the sealant may spray out.
● Keep back from the tire while it is being repaired, as there is a chance of it
bursting while the repair operation is being performed. If you notice any
cracks or deformation of the tire, turn off (type A) or (off) (type B) the
compressor switch and stop the repair operation immediately.
● The repair kit may overheat if operated for a long period of time. Do not
operate the repair kit continuously for more than 40 minutes.
● Parts of the repair kit become hot during operation. Be careful when han-
dling the repair kit during and after operation. Do not touch t he metal part
around the connecting area between the bottle and the compresso r. I t w il l
be extremely hot.
● Do not attach the vehicle speed warning sticker to an area other than the
one indicated. If the sticker is attached to an area where an S RS airbag is
located, such as the pad of the steering wheel, it may prevent the SRS
airbag from operating properly.

■ 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
● Information stored in the ECU is cleared. When the 12-volt battery is
depleted, have the vehicle inspected at any authorized Toyota r etailer or
Toyota authorized repairer, or any reliable repairer.
● Some systems may require initialization. (P. 791)

ECU is cleared. Before removing the 12-volt battery terminals, contact any
authorized Toyota retailer or Toyota authorized repairer, or an y reliable
repairer.
■ Charging the 12-volt battery
The electricity stored in the 12- volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the dra ining effects of
certain electrical appliances. If the vehicle is left for a lon g time, the 12-volt
battery may discharge, and the hybrid system may be unable to s tart. (The
12-volt battery recharges automat ically while the hybrid system is operating.)

WARNING
■After recharging the 12-volt battery (M20A-FXS engine)
Have the 12-volt battery inspected at any authorized Toyota ret ailer or
Toyota authorized repairer, or any reliable repairer as soon as possible. If
