WARNING
■When installing a booster seat
To prevent the belt from going into ALR lock mode, do not fully extend the shoulder
belt. ALR mode causes the belt to tighten only. This could cause injury or discomfort to
the child. (P. 32)
■When installing a child restraint system
Follow the directions given in the child rest raint 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 a sudden braking or an accident.
●If the driver’s seat interferes with the child
restraint system and prevents it from being
attached correctly, atta ch the child restraint
system to the right-hand rear seat.
●Adjust the front passenger seat so that it does
not interfere with the child restraint system.
●Only put a forward-faci ng child restraint sys-
tem on the front seat when unavoidable.
When installing a forward-facing child
restraint system on the front passenger seat,
move the seat as far back as possible even if
the “AIR BAG OFF” indicator light is illumi-
nated. Failure to do so may result in death or
serious injury if the airbags deploy (inflate).

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.

designed to automatically call the re sponse center. The responding agent
receives the vehicle’s location and attempts to speak with the vehicl\
e occu-
pants to assess the level of emergency. If the occupants are unable to commu-
nicate, the agent automatically treats the call as an emergency, contacts the
nearest emergency services provider to describe the situation, and requests
that assistance be sent to the location.

assist them in locating and recovering the vehicle. After filing a police report,

3987) in the United Stat es, 1-877-539-8777 in Pu erto Rico or 1-800-265-
3987 in Canada, and follow the prompts for Safety Connect to initiate this
service.
In addition to assisting law enforcemen t with recovery of a stolen vehicle,
Safety-Connect-equipped vehicle locatio n data may, under certain circum-
stances, be shared with third parties to locate your vehicle. Further informa-
tion is available at Lexus.com.
■Emergency Assistance Button (“SOS”)
In the event of an emergency on the ro ad, push the “SOS” button to reach the
Safety Connect response center. Th e answering agent will determine your
vehicle’s location, assess the emergency, and dispatch the necessary assis-
tance required.
