CAUTION
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 or other
passengers may be seriously injured or even killed in the event of sudden
braking, sudden swerving 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 (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.
Only put a forward-facing child
restraint system on the front seat when
unavoidable. When installing a for-
ward-facing child restraint system on
the front passenger seat, move the seat
as far back as possible.

CAUTION
When installing a child restraint system
If child restraint system regulations exist in the country where you reside,
please contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional for the child restraint system installa-
tion.
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 child’s
shoulder. Failing to do so may result in death or serious injury in the event
of sudden braking, sudden swerving or an accident.
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 sudden braking, sudden swerving or an accident.

Exhaust gas precautions
Harmful substance to the human body is included in exhaust gases
if inhaled.
CAUTION
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
dealer or repairer, or another duly qualified and equipped professional 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 operating, exhaust gases may collect and enter the vehi-
cle.
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 Lexus
dealer or repairer, or another duly qualified and equipped professional.
