CHILD RESTRAINT
Child restraint precautions
Lexus strongly urges the use of appropriate child
restraint systems for children.
The laws of all 50 states in the U.S.A. and Canada now require
the use of a child restraint system.
Your vehicle conforms to SAE J1819.
If a child is too large for a child restraint system, the child should
sit in the rear seat and must be restrained using the vehicle’s
seat belt. See “Seat belts” on page 168 for details.
CAUTION
 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 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.
 Lexus strongly urges use of a proper child restraint
system which 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.

OCCUPANT RESTRAINT SYSTEMS

Never install a rearfacing child restraint system on
the front passenger seat. In the event of an accident,
the force of the rapid inflation of the front passenger
airbag can cause death or serious injury to the child
if the rearfacing child restraint system is installed
on the front passenger seat.
 A forwardfacing child restraint system should be
allowed to be installed on the front passenger seat
only when it is unavoidable. Always move the seat as
far back as possible, because the front passenger
airbag could inflate with considerable speed and
force. Otherwise, the child may be killed or seriously
injured.
 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 or rear pillar 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 airbag and curtain shield airbag
inflate, and the impact could cause death or serious
injury to the child.
 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. 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.

CAUTION
Never install a rearfacing child restraint system on

the force of the rapid inflation of the front passenger
airbag can cause death or serious injury to the child
if the rearfacing child restraint system is installed

Move seat fully back
 A forwardfacing child restraint system should be
allowed to be installed on the front passenger seat
only when it is unavoidable. Always move the seat as
far back as possible, because the front passenger
airbag could inflate with considerable speed and
force. Otherwise, the child may be killed or seriously
injured.
 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 or rear pillar, 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 airbag and curtain shield
airbag inflate, and the impact could cause death or
serious injury to the child.

inflate, and the impact could cause death or serious
injury to the child.

1. Sit the child on a booster seat. Run the lap and shoulder belt
through or around the booster seat and across the child
following the instructions provided by its manufacturer and
insert the tab into the buckle taking care not to twist the belt.
Make sure the shoulder belt is correctly across the child’s
shoulder and that the lap belt is positioned as low as possible
on the child’s hips. See “Seat belts” on page 168 for details.
CAUTION
 Always make sure the shoulder belt is positioned
across the center of child’ s shoulder. The belt should
be kept away from child’s neck, but not falling off
child’s shoulder. Otherwise, the child may be killed
or seriously injured in case of sudden braking or a
collision.

Take care not to spill gasohol during refueling.
Gasohol may cause paint damage.
Fuel tank capacity
84 L (22.2 gal., 18.5 lmp.gal.)
FUEL PUMP SHUT OFF
SYSTEM323.
The fuel pump shut off system stops supplying fuel to the
engine to minimize the risk of fuel leakage when the engine
stalls or an airbag inflates upon collision. To restart the engine
after the fuel pump shut off system activates, turn the ignition
switch to “ACC” or “LOCK” once and start it.
CAUTION
Inspect the ground under the vehicle before restarting
the engine. If you find that liquid has leaked onto the
ground, it is the fuel system that has been damaged and
it is in need of repair. In this case, do not restart the
engine.
