■To prevent injury
Before performin g any light bulb
replacement procedure, be sure
to turn the power switch off. Fail-
ure to do so may result in burns
from hot components or a part of
your body may get caught on an
operating component, possibly
causing serious injury.
■Replacing light bulbs
●Turn off the lights. Do not
attempt to replace the bulb
immediately after turning off the
lights.The bulbs become very
hot and may cause burns.
●Do not touch the glass portion
of the light bulb with bare
hands. When it is unavoidable
to hold the glass portion, use
and hold with a clean dry cloth
to avoid getting moisture and
oils on the bulb. Also, if the bulb
is scratched or dropped, it may
blow out or crack.
●Fully install light bulbs and any
parts used to secure them. Fail-
ure to do so may result in heat
damage, fire, or water entering
the light unit. This may damage
the lights or cause condensa-
tion to build up on the lens.
●Do not attempt to repair or dis-
assemble light bulbs, connec-
tors, electric circuits or
component parts.
Doing so may res ult in death or
serious injury due to electric
shock.
■To prevent damage or fire
●Make sure bulbs are fully
seated and locked.
●Check the wattage of the bulb
before installing to prevent heat
damage.

■Using an emergency hammer*
for emergency escape
The front side windows and rear
side windows, as well as the rear
window can be shattered with an
emergency hammer
* used for
emergency escape.
However, an emergency hammer
*
can not shatter the windshield as
it is laminated glass.
*: Contact your Toyota dealer or
aftermarket accessory manu-
facturer for further information
about an emergency hammer.
■Escaping the vehicle from the
window
There are cases where escaping
the vehicle from the window is not
possible due to seating position,
passenger body type, etc.
When using an emergency ham-
mer, consider your seat location
and the size of the window open-
ing to ensure that the opening is
accessible and large enough to
escape.

If your vehicle needs
to be towed
If towing is necessary, we
recommend having your
vehicle towed by your Toy-
ota dealer or commercial
towing service, using a
wheel-lift type truck or flat-
bed truck.
Use a safety chain system
for all towing, and abide by
all state/provincial and local
laws.
If towing your vehicle with a
wheel-lift type truck from
the front, the vehicle’s rear
wheels and axles must be in
good conditions. ( P.457)
If they are damaged, use a
towing dolly or flatbed
truck.
WA R N I N G
Observe the following precau-
tions.
Failure to do so m ay result in
death or serious injury.
■When towing the vehicle
2WD models
Be sure to transp ort 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 ma y be damaged or
electricity generated by the opera-
tion of the motor may cause a fire
to occur depending on the nature
of the damage or malfunction.
AWD models
Be sure to transp ort the vehicle
with all four wheels raised off the
ground. If the vehicle is towed
with the tires co ntacting the
ground, the drivetrain or related
parts may be damaged, the vehi-
cle may fly off the truck, or elec-
tricity generated by the operation
of the motor may cause a fire to
occur depending o n the nature of
the damage or malfunction.

The following may indicate a
problem with your transmission.

commercial towing service
before towing.
The hybrid system warning
message is shown on the
multi-information display and

The vehicle makes an abnor-
mal sound.

■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 dam-
age.
●Do not turn the power switch off.
There is a possibility that the
steering wheel is locked and
cannot be operated.
NOTICE
■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 mecha-
nism is not strong enough to
hold the front wheels straight.
●When raising the vehicle,
ensure adequate ground clear-
ance for towing at the opposite
end of the raised vehicle. With-
out adequate clearance, 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 truck,
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.
■Recreational towing (behind
motor home, etc.)
Never dinghy tow your vehicle to
prevent causing serious damage
to the Hybrid AWD system (AWD
models) and transmission.

essary to contact dealers
