IS350 AWD/IS350/IS300 AWD/IS300_U
●It is recommended that children sit in the rear seats to avoid accidental con-
tact with the shift lever, wiper switch etc.
●Use the rear door child-protector lock or the window lock switch to avoid
children opening the door while driving or operating the power window acci-
dentally.
●Do not let small children operate equipment 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 appropriate for the child, until the child becomes
large enough to properly wear the vehicle’s seat belt.
WARNING
Never leave children unattended in the vehicl e, and never allow children to have or use
the key.
Children may be able to start the vehicle or sh ift the vehicle into neutral. There is also a
danger that children may injure themselves by playing with the windows, the moon roof
or other features of the vehi cle. In addition, heat build-up or extremely cold tempera-
tures inside the vehicle can be fatal to children.

WARNING
■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 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 rest raint 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.

Exhaust gas precautions
Harmful substance to the human body is included in exhaust gases if inhaled.
WARNING
Exhaust gases include harmful carbon monoxi de (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 your Lexus dealer 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 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 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 sure to have the vehicle
inspected and repaired by your Lexus dealer.
