LS500_OM_(U)_1810 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 precau-
tions.
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 vehi-
cle even when the trunk lid is closed,
open the windows and have the vehi-
cle 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.

WARNING
■
When using a child restraint system
Observe the following precautions.
Failure to do so may result in death or
serious injury.
●
Never install a rear-facing child
restraint system on the front passenger
seat even if the “AIR BAG OFF” indi-
cator light is illuminated. In the event of
an accident, the force of the rapid infla-
tion of the front passenger airbag can
cause death or serious injury to the
child if the rear-fac ing child restraint
system is installed on the front passen-
ger seat.

491-2. Child safety
LS500_OM_(U)_1810 1
For safety and security
A child restraint system for a small
child or baby must itself be properly
restrained on the seat with the lap por-
tion of the lap/shoulder belt. ■
Installing child restraint system
using a seat belt (child restraint
lock function belt)
Install the child restraint system in
accordance to the operation manual
enclosed with the child restraint sys-
tem.WARNING●
A forward-facing child restraint system
may be installed on the front passen-
ger seat only when it is unavoidable. A
child restraint 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.●
A forward-facing child restraint system
may be installed on the front passen-
ger seat only when it is unavoidable.
When installing a forward-facing child
restraint system on the front passenger
seat, adjust the seatback angle to the
most upright position, move the seat to
the rearmost position, and raise the
seat to the upper most position, even if
the “AIR BAG OFF” indicator light is
illuminated.
●
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 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 and curtain shield airbags
inflate, and the impact could cause
death or serious injury to the child. ●
When a booster seat is installed,
always ensure that th e 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. ●
Use child restraint system suitable to
the age and size of the child and install
it to the rear seat. ●
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.
●
Adjust the front passe nger seat so that
it does not interfere with the child
restraint system.

Automatic Collision Notification

designed to automatically call the
response center. The responding agent
receives the vehicle’s location and
attempts to speak with the vehicle
occupants to assess the level of emer-
gency. If the occupants are unable to
communicate, the ag ent automatically
treats the call as an emergency, con-
tacts the nearest emergency services
provider to describe the situation, and
requests that assistance be sent to the
location. ■
Stolen Vehicle Location
If your vehicle is stolen, Safety Connect
can work with local authorities to assist
them in locating and recovering the
vehicle. After filing a police report, call

nect to initiate this service.

ment with recovery of a stolen vehicle,

cumstances, be shared with third par-
ties to locate your vehicle. Further
