1-6. Theft deterrent system
Engine immobilizer system
■System maintenance
The vehicle has a maintenance-free type engine immobilizer system.
■ Conditions that may cause the system to malfunction
●If the key is in contact with a metallic object
● If the key is in close proximity to or touching a key to the security system
(key with a built-in transponder chip) of another vehicle
■ Certifications for the en gine immobilizer system
For vehicles sold in the U.S.A.
FCC ID: MOZRI-42BTY
This device complies with part 15 of the FCC Rules. Operation is subject to
the following two conditions: (1) This device may not cause harmful interfer-
ence, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
The vehicle’s keys have built-in tr ansponder chips that prevent the
engine from starting if the key has not been previously registered in
the vehicle’s on-board computer.
Never leave the keys inside the vehicle when you leave the vehicle.
This system is designed to help prevent vehicle theft but does not
guarantee absolute security against all vehicle thefts.
The indicator light flashes after
the key has been removed
from the engine switch to indi-
cate that the system is operat-
ing.
The indicator light stops flash-
ing after the registered key
has been inserted into the
engine switch to indicate that
the system has been can-
celed.

1-7. Safety information

Before driving
Your vehicle is equipped with
ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag
sensor assembly (ECU) controls ai rbag deployment based on infor-
mation obtained from the sensors etc. shown in the system compo-
nents diagram above. This inform ation includes crash severity and
occupant information. As the air bags deploy, a chemical reaction in
the inflators quickly fills the airbag s with non-toxic gas to help restrain
the motion of the occupants.
■ SRS warning light
This warning light system monitors the airbag sensor assembly, front airbag
sensors, side and curtain shield airbag sensor assemblies, curtain shield air-
bag sensor assemblies, driver’s seat position sensor, driver’s seat belt
buckle switch, front passenger occupant classification system (ECU and
sensors), AIR BAG ON and AIR BAG OFF indicator lights, front passenger’s
seat belt buckle switch, front seat belt pretensioner assemblies, airbags,
interconnecting wiring and power sources. ( P. 558)
■ If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator)
as well as the front seats, and parts of the front and rear pillars and roof
side rail, may be hot for several minutes. The airbag itself may also be
hot.
● The front windshield may crack.

Before driving
CAUTION
■
SRS airbag precautions
●The SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
● Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. An infant or child who is too small
to use a seat belt should be properly secured using a child restraint sys-
tem. Toyota strongly recommends that all infants and children be placed in
the rear seats of the vehicle and properly restrained. The rear seats are
the safest for infants and children. ( P. 128)
●If the seat belt extender has been con-
nected to the front seat belt buckles but
the seat belt extender has not also
been fastened to the latch plate of the
seat belt, the SRS front airbags will
judge that the driver and front passen-
ger are wearing the seat belt even
though the seat belt has not been con-
nected. In this case, the SRS front air-
bags may not activate correctly in a
collision, resulting in death or serious
injury in the event of a collision. Be sure
to wear the seat belt with the seat belt
extender.

130 1-7. Safety information
CAUTION
■Child restraint precautions
●For effective protection in automobile accidents and sudden stops, a child
must be properly restrained, using a seat belt or child restraint system
depending on the age and size of the child. Holding a child in your arms is
not a substitute for a child restraint system. In an accident, the child can be
crushed against the windshield, or between you and the vehicle’s interior.
● Toyota strongly urges the use of a proper child restraint system that con-
forms to the size of the child, installed on the rear seat. According to acci-
dent statistics, the child is safer when properly restrained in the rear seat
than in the front seat.
● Never install a rear-facing child restraint system on the front passenger
seat even if the AIR BAG OFF indicator light is illuminated.
In the event of an accident, the force of the rapid inflation of the front pas-
senger airbag can cause death or serious injury to the child if the rear-fac-
ing child restraint system is installed on the front passenger seat.
● A forward-facing child restraint system may be installed on the front pas-
senger seat only when it is unavoidable. A child restraint system that
requires a top tether strap should not be used in the front passenger seat
since there is no top tether strap anchor for the front passenger seat.
Adjust the seatback as upright as possible and always move the seat as
far back as possible even if the AIR BA G OFF indicator light is illuminated,
because the front passenger airbag could inflate with considerable speed
and force. Otherwise, the child may be killed or seriously injured.
● Do not use the seat belt extender when installing a child restraint system
on the front or rear passenger seat. If installing a child restraint system
with the seat belt extender connected to the seat belt, the seat belt will not
securely hold the child restraint system, which could cause death or seri-
ous injury to the child or other passengers in the event of a sudden stop,
sudden swerve or accident.
● Do not allow the child to lean his/her head or any part of his/her body
against the door or the area of the sea t, front and rear pillars or roof side
rail from which the side airbags or curtain shield airbags deploy even if the
child is seated in the child restraint system. It is dangerous if the side air-
bags and curtain shield airbags inflate, and the impact could cause death
or serious injury to the child.

CAUTION
■
Child restraint precautions
●Make sure you have complied with all installation instructions provided by
the child restraint manufacturer and that the system is properly secured. If
it is not secured properly, it may cause death or serious injury to the child
in the event of a sudden stop, sudden swerve or accident.
■ When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, it may lead to choking or other serious injuries
that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
■ When the child restrain t system is not in use
● Keep the child restraint system properly secured on the seat even if it is
not in use. Do not store the restraint unsecured in the passenger compart-
ment.
● If it is necessary to detach the child restraint system, remove it from the
vehicle or store it securely in the luggage compartment. This will prevent it
from injuring passengers in the event of a sudden stop, sudden swerve or
accident.

Installing child restraints
Follow the child restraint system manufacturer’s instructions. Firmly
secure child restraints to the r ear seats using the LATCH anchors or
a seat belt. Attach the top tether strap when installing a child
restraint.
The lap/shoulder belt can be used if your child restraint system is
not compatible with the LATCH (Low er Anchors and Tethers for Chil-
dren) system.

top tether strap, the top
tether strap should be
latched onto the top
tether strap anchor.

138 1-7. Safety information
While pushing the child seat
down into the rear seat, allow the
shoulder belt to retract until the
child seat is securely in place.
After the shoulder belt has
retracted to a point where there is
no slack in the belt, pull the belt to
check that it cannot be extended.
■Forward facing Convertible seat
Place the child seat on the seat
facing the front of the vehicle.
Run the seat belt through the
child seat and insert the plate
into the buckle. Make sure that
the belt is not twisted.
Fully extend the shoulder belt
and then allow it to retract
slightly in order to activate the
ALR lock mode.
Lock mode allows the seat belt to
retract only.
