WARNING
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. ( P. 46)
■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.
■Seat belt pretensioners
If the pretensioner has activated, the SRS warning light will come on. In that case, the
seat belt cannot be used again and must be replaced at any authorized Lexus retailer
or Lexus authorized repairer, or any reliable repairer.
■Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your shoulder.
The belt should be kept away from your ne ck, but not falling off your shoulder. Failure to
do so could reduce the amount of protection in an accident and cause death or serious
injuries in the event of a sudden stop, sudden swerve or accident. ( P. 47)
■Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate, or buckle to be jammed in
the door.
●Inspect the seat belt system periodically. Check for cuts, fraying, and loose parts. Do
not use a damaged seat belt until it is re placed. Damaged seat belts cannot protect an
occupant from death or serious injury.
●Ensure that the belt and plate are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately contact any authorized Lexus
retailer or Lexus authorized repa irer, or any reliable repairer.
●Replace the seat assembly, including the belts, if your vehicle has been involved in a
serious accident, even if there is no obvious damage.
●Do not attempt to install, remove, modify, disassemble or dispose of the seat belts.
Have any necessary repairs carried out by any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repa irer. Inappropriate handling may lead to
incorrect operation.

WARNING
■When installing a child restraint system
For safety reasons, always install a child rest raint 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 serious 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.

For safety and security
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 reliable 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
engine.
●Do not leave the vehicle with the engine running 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 engine running in an area with snow build-up, or where it is snowing.
If snowbanks build up around the vehicle while the engine is running, 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 sur e to have the vehicle
inspected and repaired by any authorized Le xus retailer or Lexus authorized repairer,
or any reliable repairer.
