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 wind-
shield, or between you and the vehicle’s interior.
●Lexus strongly urges the use of a proper child restraint system that conforms to
the size of the child, installed on the rear seat. According to accident 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 passenger airbag can cause death or seri-
ous injury to the child if the rear-facing child restraint system is installed on the
front passenger seat.
●A forward-facing child restraint system should allowed to be installed on the front
passenger seat only when it is unavoidable. Always move the seat as far back as
possible even if the “AIR BAG OFF” indicator light is illuminated, because the
front passenger airbag could inflate with considerable speed and force. Other-
wise, 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 serious injury to the child or other
passengers in the event of collision.
●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 seat, front pillar or roof side rail from which the side air-
bags or curtain shield airbags deploy even if the child is seated in the child
restraint system. It is dangerous if the side airbags and curtain shield airbags
inflate, and the impact could cause death or serious injury to the child.
●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 or accident.

1-7. Safety information
While pushing the child seat down
into the 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 strap and
then allow it to retract slightly into
the ALR lock mode.
Lock mode allows the seat belt to
retract only.

Before driving
CAUTION
■When installing a booster seat
Do not fully extend the shoulder belt to prevent the belt from going to ALR lock
mode: ( →P. 5 2 )
●ALR mode causes the belt to tighten only which could cause injury or discomfort
to the child.
●Do not allow the child to play with the seat belt or the child could be killed or seri-
ous injured.
■When installing a child restraint system
Follow the directions given in the child restraint system installation manual and fix
the child restraint system securely in place.
If the child restraint system is not correctly fixed in place, the child may be injured or
even killed in the event of sudden braking or an accident.
●If the driver’s seat interferes with the child
restraint system and prevents it from being
attached correctly, attach the child restraint
system to the right-hand rear seat.
●Only put a forward facing or booster child
seat on the front seat when unavoidable.
When installing a forward facing or
booster child seat on the front passenger
seat, move the seat as far back as possible
even if the “AIR BAG OFF” indicator light is
illuminated. Failing to do so may result in
death or serious injury if the airbags deploy
(inflate).

1-7. Safety information
CAUTION
■When installing a child restraint system
●When a booster seat is installed, always ensure that the shoulder belt is posi-
tioned across the center of the child’s shoulder. The belt should be kept away from
the child’s neck, but not so that it could fall off the child’s shoulder. Failing to do so
may result in death or serious injury in the event of an accident or sudden braking.
●Ensure the belt and tab are securely locked and that the seat belt is not twisted.
●Push and pull the child seat in different directions to be sure it is secure.
●Follow all installation instructions provided by the child restraint system manufac-
turer.
■Do not use a seat belt extender
If a seat belt extender is used when installing a child restraint system, the seat belt
will not securely hold the child restraint system, which could cause death or serious
injury to the child or other passengers in the event of a collision.
■To correctly attach a child restraint system to the anchorages
When using the lower anchorages, be sure that there are no foreign objects around
the anchorages and that the seat belt is not caught behind the child restraint. Make
sure the child restraint system is securely attached, or it may cause death or serious
injury to the child in the event of a sudden stop or accident.
●When installing a child restraint system in
the third center position, set the both seat-
backs to the same angle. Otherwise, the
child restraint system cannot be properly
secured.

Make sure the child restraint system is securely attached, or it may cause death or
serious injury to the child in the event of a sudden stop or accident.
●When using the left side lower anchorages
for the child restraint system, do not sit in
the center seat. Seat belt function may be
impaired, such as being positioned overly
high or loose-fitting, which may result in
death or serious injury in the event of a col-
lision.

2-1. Driving procedures
CAUTION
■When taking a nap in the vehicle
Always turn the engine off.
Otherwise, you may accidentally move the shift lever or depress the accelerator
pedal, which could cause an accident or fire due to engine overheating. Addition-
ally, if the vehicle is parked in a poorly ventilated area, exhaust gases may collect
and enter the vehicle, leading to death or a serious health hazard.
■When braking the vehicle
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and may cause one side of
the vehicle to brake differently than the other side. Also the parking brake may
not securely hold the vehicle.
●If the power brake assist function does not operate, do not follow other vehicles
closely and avoid downhill or sharp turns that require braking.
In this case, braking is still possible, but it will require more force on the pedal than
usual. Braking distance may also increase.
●Do not pump the brake pedal if the engine stalls.
Each push on the pedal uses up the reserve for the power-assisted brakes.
●The brake system consists of 2 individual hydraulic systems: if one of the systems
fails, the other will still operate. In this case, the brake pedal should be depressed
more firmly than usual and braking distance becomes longer.
Do not drive your vehicle with only a single brake system. Have your brakes fixed
immediately.
NOTICE
■While driving the vehicle
Do not use the accelerator pedal or depress accelerator and brake pedals together
to hold the vehicle on a hill.
■When parking the vehicle
Always put the shift lever in “P”. Failure to do so may cause the vehicle to move or
the vehicle may accelerate suddenly if the accelerator pedal is accidentally
depressed.

underneath the luggage compartment for several minutes. This is normal operation
and does not indicate a malfunction. When starting the engine, the engine switch
may seem stuck in the “LOCK” position. To
free it, turn the key while turning the steering
wheel slightly in either direction.
