If your vehicle is transported by a
flatbed truck, it should be tied
down at the locations shown in the
illustration.
If you use chains or cables to tie
down your vehicle, the angles
shaded in black must be 45°.
Do not overly tighten the tie
downs or the vehicle may be dam-
aged.
If a tow truck is not available in an emergency, your vehicle may be
temporarily towed using cables or chains secured to the emergency
towing eyelets. This should only be attempted on hard surfaced roads
for short distances at under 18 mph (30 km/h).
A driver must be in the vehicle to steer and operate the brakes. The
vehicle’s wheels, drive train, axles, steering and brakes must be in
good condition.

■While towing
If the hybrid system is off, the power assist for the brakes and steering will not
function, making steering and braking more difficult.
■ Wheel nut wrench
Wheel nut wrench is installed in luggage compartment. ( →P. 610)
■ Towing eyelet installation hole on the rear of the vehicle
The hole is equipped for fastening the
vehicle while shipping. Your vehicle can-
not tow another vehicle.
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 eye-
lets, cables or chains may become damaged, broken debris may hit peo-
ple, and cause serious damage.
● Do not turn the power switch off.
This may lead to an accident as the front wheels will be locked by the
parking lock.
■ Installing towing eyelets to the vehicle
● The towing eyelets are only for the vehicle equipped with them. Do not use
the towing eyelets for another vehicle, and do not use the towing eyelets
for this vehicle on another 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
■When recharging or repl acing the 12-volt battery
● In some cases, it may not be possible to unlock the doors using the smart
key 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.
● Vehicles with smart lid & connector locking system:
It may be impossible to unlock the charging port lid or locking and unlocking
the charging connector immediately after the 12-volt battery is reconnected.
In this case, carry the electronic key on your person and operate the
charging port lid or charging connector lock switch again.
● 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 bat-
tery discharged, be especially careful when reconnecting the 12-volt battery.
● If the 12-volt battery discharges while the shift position is in P, it may not be
possible to shift the shift position to other positions. In this case, the vehicle
cannot be towed without lifting both front wheels because the front whee\
ls
will be locked. ( →P. 646)
■ When exchanging the 12-volt battery
●Use a 12-volt battery that conforms to European regulations.
● Use a 12-volt battery that the case size is same as the previous one (LN1),
20 hour rate capacity (20HR) is equivalent (45Ah) or greater, and perfor-
mance rating (CCA) is equivalent (295A) or greater.
• If the sizes differ, the 12-volt battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehi-
cle is not used is a short time, the 12-volt battery may discharge and the
hybrid system may not be able to start.
● For details, consult your Toyota dealer.

WARNING
■When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the
surrounding area is clear to avoid striking other vehicles, objects or people.
The vehicle may also lunge forward or lunge back suddenly as it becomes
free. Use extreme caution.
■ When changing the shift position
Be careful not to change the shift position with the accelerator pedal
depressed.
This may lead to unexpected rapid acceleration of the vehicle that may
cause an accident resulting in death or serious injury.
NOTICE
■To avoid damage to the hybrid transmission and other components
● Avoid spinning the front wheels and depressing the accelerator pedal
more than necessary.
● If the vehicle remains stuck even after these procedures are performed,
the vehicle may require towing to be freed.
