For safety reasons, always inst all a child restraint system in a rear seat. In the event that the rear seat cannot be used, the front seat can be used as long as the airbag manual
on-off system is set to off.
If the airbag manual on-off system is left on, the strong impact of the airbag deployment (inflation) may cause seriou s injury or even death.
■When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off system is set to on. If it is left off, the airbag may not deploy in the event of an accident, which may result in
serious injury or even death.

The Pop Up Hood will operate when the vehicle detects an impact such as the
following:
●The front bumper detects a frontal impact equivalent to or greater than that of
a pedestrian while the vehicle being driv en within the operational speed range
of approximately 25 to 55 km/h (16 to 34 mph). (The system is operated by
an impact of threshold level or greater, even in the case of a minor collision
that may not leave a trace on the fron t bumper. Also, depending on the impact
conditions or vehicle speed , the system may be operated by a collision with a
light or small object or a small animal.)
●In other situations the system may oper ate when an impact is applied to the
lower part of the vehicle or front bumper, such as the following:
• Colliding with a curb
• Falling into a deep hole
•Landing hard
• Hitting the slope of a parking lot, an undulating road, a protruding object or
falling object
Pop Up Hood operational conditions
WARNING
■When the Pop Up Hood is operated
●Do not pull the hood lock release lever. Doing so after the Pop Up Hood has oper-
ated will further raise the h ood and may cause an injury. Do not drive with the hood raised, as doin g so may block the driver’s vision, possibly
causing an accident.
Do not forcibly push down the hood. As the popped up hood cannot be lowered by hand, doing so may deform th e hood or cause an injury.
If the Pop Up Hood has operated, have the vehicle inspected by any authorized
Lexus retailer or Lexus author ized repairer, or any reliable repairer. If the Pop Up Hood has operated, stop the vehicle in a sa fe place and contact any authorized Lexus
retailer or Lexus authorized repa irer, or any reliable repairer.
●Do not touch the lifters immediately after the Pop Up Hood has operated, as the lift- ers may be hot and burn you.

children opening the door while drivin g or operating the power window acci-
dentally.
●Do not let small children operate equi pment which may catch or pinch body
parts, such as the power window, hood, trunk, seats etc.
Safety information for children
Observe the following precautions when children are in the vehicle.
Use a child restraint system appropriat e for the child, until the child becomes

■When installing a child restraint system on the front passenger seat
■Selecting an appropriate child restraint system
●Use a child restraint system appropriate for the child until the child becomes large enough to properly wear the vehicle’s seat belt.
●If the child is too large for a child restraint sy stem, sit the child on a rear seat and use the
vehicle’s seat belt. ( P. 38)
When you have to use a child restraint system on the front passenger seat, adjust the following:
●The seatback to the most upright position
●The seat cushion to the highest position
●The seat cushion to the fully rearward position
WARNING
■Using a child restraint system
The use of a child restraint system not suitable for the vehicle may not properly secure
the infant or child. It may result in death or serious injury (in the event of sudden braking or an accident).

WARNING
■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. This may cause death or serious injury to the child in the
event of a sudden stop, su dden swerve or accident.
●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 restra ined in the rear seat than in the front seat.
●Never use a rear-facing child restraint system on the front passenger seat when the
airbag manual on-off switch is on. ( P. 53)
In the event of an accident, the force of the rapid inflation of the front passenger air- bag can cause death or serious injury to the child.
●A forward-facing child restraint system ma y be installed on the front passenger seat
only when it is unavoidable. A child restra int 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 po ssible because the front passenger airbag could inflate with considerable speed and fo rce. 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, center an d rear pillars or roof side rails from which
the SRS side airbags or SRS curtain shield ai rbags deploy even if the child is seated in
the child restraint system. It is dangerous if the SRS side airbags and curtain shield air- bags inflate, and the impact could caus e 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, 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 othe r serious injuries that could result in death.
If this occurs and the buckle cannot be unfa stened, scissors should be used to cut the belt.
■When the child restraint system is not in use
●Keep the child restraint system properly secure d on the seat even if it is not in use. Do not store the child restraint system un secured in the passenger compartment.
●If it is necessary to detach the child restraint system, remove it from the vehicle or
store it securely in the trunk. This will prevent it from injuring passengers in the event
of a sudden stop, sudden swerve or accident.

attached correctly, atta ch the child restraint
system to the right-hand rear seat (left-hand drive vehicles) or the left-hand rear seat
(right-hand drive vehicles).
●Adjust the front passenger seat so that it does not interfere with the child restraint system.
●When installing a forward-facing child
restraint system on the front passenger seat, move the seat as far back as possible.
Failure to do so may result in death or serious
injury if the airbags deploy (inflate).

WARNING
■When installing a child restraint system
●If child restraint system regulations exist in the country where you reside, please con-
tact any authorized Lexus retailer or Le xus authorized repairer, or any reliable
repairer for the child rest raint system installation.
●When a junior seat is installed, always ensure that the shoulder belt is positioned
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 ch ild’s shoulder. Failing to do so may result in death or serious injury in the event of su dden braking, sudden swerving or an acci-
dent.
●Ensure that the belt and plate are securely locked and the seat belt is not twisted.
●Shake the child restraint system left and right, and forward and backward to ensure
that it has been securely installed.
●After securing a child restraint system, never adjust the seat.
●Follow all installation instructions provided by the child restraint system manufacturer.
■To correctly attach a child restraint system to the anchors
When using the lower anchors, be sure that there are no foreign objects around the anchors and that the seat belt is not caught behind the child restraint system. Make sure
the child restraint system is securely attached , or it may cause death or serious injury to
the child or other passengers in the event of a sudden braking, sudden swerve or an accident.

Exhaust gas precautions
Harmful substance to the human body is included in exhaust gases if inhaled.
WARNING
Exhaust gases include harmful carbon monoxide (CO), which is colorless and odorless. Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to an accident
caused by light-headedness, or may lead to death or a serious health hazard.
■Important points while driving
●Keep the trunk lid closed.
●If you smell exhaust gases in the vehicle even when the trunk lid is closed, open the windows and have the vehicle inspected at any authorized Lexus retailer or Lexus
authorized repairer, or any reliab le repairer as soon as possible.
■When parking
●If the vehicle is in a poorly ventilated area or a closed area, such as a garage, stop the
hybrid system.
●Do not leave the vehicle with the hybrid system on for a long time. If such a situation cannot be avoided, park the vehicle in an open space and ensure
that exhaust fumes do not enter the vehicle interior.
●Do not leave the hybrid system operating in an area with snow build-up, or where it is snowing. If snowbanks build up around the vehicle while the hybrid system is operat-
ing, exhaust gases may collect and enter the vehicle.
■Exhaust pipe
The exhaust system needs to be checked periodically. If there is a hole or crack caused
by corrosion, damage to a joint or abnormal exhaust noise, be sure to have the vehicle
inspected and repaired by any authorized Le xus retailer or Lexus authorized repairer, or any reliable repairer.
