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 lower anchors and then tighten the top tether
strap.
■Laws and regulations pe rtaining 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.

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 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 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).

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 injury in the event of sudden braking, sudden
swerving or an accident.
●Make sure the rear seat head restraints 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 installing 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 attached, 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.

When driving

■Starting off on a hill
Hill-start assist control will operate. (→P. 2 2 0 )
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially
slippery.
●Refrain from high speeds when driving on an expressway in the rain, because
there may be a layer of water between the tires and the road surface, preventing
the steering and brakes from operating properly.
■Engine speed while driving
In the following conditions, the engine speed may become high while driving. This is
due to automatic up-shifting control or down-shifting implementation to meet driv-
ing conditions. It does not indicate sudden acceleration.
●The vehicle is judged to be driving uphill or downhill
●When the accelerator pedal is released

●For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low gears.
• Do not drive at a constant speed for extended periods.
■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake sys-
tem needs bedding-down of the brake shoes periodically or whenever the parking
brake shoes and/or drum are replaced. Have your Lexus dealer perform the bed-
ding down.
