STEP2
■When installing a child restraint system with lower anchors and a top tether strap
Depending on the child restraint system's si ze and shape, if the child restraint sys-
tem is installed to the LATCH anchors first, it may not be possible to attach the top
tether strap to the anchor bracket.
In that case, first temporarily attach the top tether strap to the anchor bracket, install
the child restraint system using the lowe r anchors and then tighten the top tether
strap.
■Laws and regulations pertaining to anchorages
The LATCH system conforms to FMVSS225 or CMVSS210.2.
Child restraint systems conforming to FMVSS213 or CMVSS213 specifications
can be used.
This vehicle is designed to conform to the SAE J1819.

Before driving
CAUTION
■When installing a booster seat
Do not fully extend the shoulder belt to prevent the belt from going to ALR lock
mode: (P. 7 2 )
ALR mode causes the belt to tighten only which could cause injury or discomfort to
the child.
■When installing a child restraint system
Follow the directions given in the child re straint system installation manual and fix
the child restraint system securely in place.
If the child restraint system is not correctl y fixed in place, the child or other passen-
gers may be 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.
●Only put a forward facing child restraint
system 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
illuminated. Failing to do so may result in
death or serious injury if the airbags deploy
(inflate).

136
1-7. Safety information
CAUTION
■When installing a child restraint system
●When a booster seat is installed, always ensure that the shoulder belt is posi-
tioned 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 inju ry in the event of sudden braking, sudden
swerving or an accident.
●Make sure the rear seat head restra ints are not in the folded position.
●Ensure that the belt and tab are securely locked and the seat belt is not twisted.
●Push and pull the child seat from side to side and forward to be sure it is secure.
●After securing a child restraint system, never adjust the seat.
●Follow all installation instructions provided by the child restraint system manufac-
turer.
■Do not use a seat belt extender
If a seat belt extender is used when inst alling a child restraint system, the seat belt
will not securely hold the child restraint system, which could cause death or serious
injury to the child or other passengers in the event of sudden braking, sudden
swerving or an accident.
■To correctly attach a child restraint system to the anchors
When using the LATCH anchors, be sure that there are no foreign objects around
the anchors and that the seat belt is not caught behind the child restraint. Make sure
the child restraint system is securely at tached, or it may cause death or serious
injury to the child or other passengers in the event of a sudden stop, sudden swerve
or accident.
NOTICE
■When using an anchor bracket
To avoid cover damage, be careful not to open the cover too widely.

2-1. Driving procedures
CAUTION
●If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, always depress the brake pedal and securely
apply the parking brake as needed.
●Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause the
exhaust system to overheat, which could result in a fire if combustible material is
nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehi-
cle when it is in the sun.
Doing so may result in the following.
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic
material of eye glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of
the vehicle, and may also cause a short circuit in the vehicle's electrical com-
ponents.
●Always apply the parking brake, shift the shift lever to P (vehicles with an auto-
matic transmission only), stop the engine and lock the vehicle.
Do not leave the vehicle unattend ed while the engine is running.
●Do not touch the exhaust pipe while the engine is running or immediately after
turning the engine off.
Doing so may cause burns.
●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 vehi cle. This may lead to death or a seri-
ous health hazard.

When driving
CAUTION
■Exhaust gases
Exhaust gases include harmful carbon monoxide (CO) that is colorless and odor-
less. Inhaling exhaust gases may lead to death or a serious health hazard.
●If the vehicle is in a poorly ventilated ar ea, stop the engine. In a closed area, such
as a garage, exhaust gases may collect and enter the vehicle. This may lead to
death or a serious health hazard.
●The exhaust should be checked occasionally. If there is a hole or crack caused by
corrosion, damage to a joint or abnormal exhaust noise, be sure to have the vehi-
cle inspected and repaired by your Lexus dealer. Failure to do so may allow
exhaust gases to enter the vehicle, result ing in death or a serious health hazard.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, you may accidentally move the shift lever or
depress the accelerator pedal, which could cause an accident or fire due to engine
overheating. Additionally, if the vehicle is parked in a poorly ventilated area, exhaust
gases may collect and enter the vehicle, lead ing to death or a serious health hazard.
■When braking the vehicle
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and may cause one side of
the vehicle to brake differently than the other side. Also the parking brake may
not securely hold the vehicle.
●If the power brake assist function does not operate, do not follow other vehicles
closely and avoid downhills or sharp turns that require braking.
In this case, braking is still possible, but it will require more force on the pedal than
usual. Braking distance may also increase.
●Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted brakes.
●The brake system consists of 2 individual hydraulic systems: if one of the systems
fails, the other will still operate. In this case, the brake pedal should be depressed
more firmly than usual and braking distance becomes longer.
Do not drive your vehicle with only a single brake system. Have your brakes fixed
immediately.
