CAUTION
■When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes twisted
around a child’s neck, it may lead to choking or other serious injuries that could
result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used to cut
the belt.
■Seat belt pretensioners
●Do not place anything, such as a cushion, on the front passenger's seat. Doing so
will disperse the passenger's weight, wh ich prevents the sensor from detecting
the passenger's weight properly. As a resu lt, the seat belt pretensioner for the
front passenger's seat may not activate in the event of a collision.
●If the pretensioner has activated, the SRS warning light will come on. In that case,
the seat belt cannot be used again and must be replaced at your Lexus dealer.
■Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your shoul-
der. The belt should be kept away from yo ur neck, but not falling off your shoulder.
Failure to do so could reduce the amount of protection in an accident and cause
death or serious injuries in the event of a sudden stop, sudden swerve or accident.
(  P. 3 7 )
■Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate, or buckle to be jammed
in the door.
●Inspect the seat belt system periodically. Check for cuts, fraying, and loose parts.
Do not use a damaged seat belt until it is replaced. Damaged seat belts cannot
protect an occupant from death or serious injury.
●Ensure that the belt and plate are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately contact your Lexus
dealer.
●Replace the seat assembly, including the belts, if your vehicle has been involved in
a serious accident, even if there is no obvious damage.
●Do not attempt to install, remove, modify, disassemble or dispose of the seat belts.
Have any necessary repairs carried out by your Lexus dealer. Inappropriate han-
dling may lead to incorrect operation.

For safety and security
LS600hL_U(OM50E41U)
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag sen-
sor assembly (ECU) controls airbag deployment based on information
obtained from the sensors etc. show n in the system components diagram
above. This information includes crash severity and occupant information.
As the airbags deploy, a chemical reaction in the inflators quickly fills the
airbags with non-toxic gas to help restrain the motion of the occupants.
CAUTION
■SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may caus e death or serious injury.
●The driver and all passengers in the vehi cle must wear their seat belts properly.
The SRS airbags are supplemental devices to be used with the seat belts.
●The SRS driver airbag deploys with considerable force, and can cause death or
serious injury especially if the driver is very close to the airbag. The National
Highway Traffic Safety Admi nistration (NHTSA) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm) of
inflation, placing yourself 10 in. (250 mm) from your driver airbag provides you
with a clear margin of safety. This distance is measured from the center of the
steering wheel to your breastbone. If you sit less than 10 in. (250 mm) away now,
you can change your driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals comfortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many drivers can achieve the 10 in. (250 mm)
distance, even with the driver seat all the way forward, simply by reclining the
back of the seat somewhat. If reclining the back of your seat makes it hard to
see the road, raise yourself by using a fi rm, non-slippery cushion, or raise the
seat if your vehicle has that feature.
• If your steering wheel is adjustable, ti lt it downward. This points the airbag
toward your chest instead of your head and neck.
The seat should be adjusted as reco mmended by NHTSA above, while still
maintaining control of the foot pedals, steering wheel, and your view of the
instrument panel controls.

LS600hL_U(OM50E41U)
CAUTION
■SRS airbag precautions
●Do not hang coat hangers or hard objects on the coat hooks. All of these items
could become projectiles and may cause death or serious injury, should the SRS
curtain shield airbags deploy.
●If a vinyl cover is put on the area where the SRS knee airbag will deploy, be sure to
remove it.
●Do not use seat accessories which cover the parts where the SRS side airbags
and seat cushion airbag inflate as they may interfere with inflation of the SRS air-
bags. Such accessories may prevent the side airbags and seat cushion airbag
from activating correctly, disable the system or cause the side airbags and seat
cushion airbag to inflate accidentally, resulting in death or serious injury.
●Do not strike or apply significant levels of force to the area of the SRS airbag
components. Doing so can cause the SRS airbags to malfunction.
●Do not touch any of the component part s immediately after the SRS airbags have
deployed (inflated) as they may be hot.
●If breathing becomes difficult after the SRS airbags have deployed, open a door
or window to allow fresh air in, or leave the vehicle if it is safe to do so. Wash off
any residue as soon as possible to prevent skin irritation.
●If the areas where the SRS airbags are stored, such as the steering wheel pad and
front and rear pillar garnishes are damaged or cracked, have them replaced by
your Lexus dealer.
●Do not place anything, such as a cushion, on the front passenger's seat. Doing so
will disperse the passenger's weight, wh ich prevents the sensor from detecting
the passenger's weight properly. As a result, the SRS front passenger airbag may
not deploy in the event of a collision.

821-2. Hybrid system
LS600hL_U(OM50E41U)
There are air intake vents on the
package tray for the purpose of
cooling the hybrid battery (traction
battery). If the vents become
blocked, the hybrid battery may
overheat, leading to a reduction in
hybrid battery output.
When a certain level of impact is detected by the impact sensor, the emer-
gency shut off system blocks off the high voltage current and stops the fuel
pump to minimize the risk of electr ocution and fuel leakage. If the emer-
gency shut off system activates, your ve hicle will not restart. To restart the
hybrid system, contact your Lexus dealer.
A message is automatically displayed when a malfunction occurs in the
hybrid system or an improper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the instruc-
tions.

■Head restraint precautions
Observe the following precautions regarding the head restraints. Failure to do so
may result in death or serious injury.
●Use the head restraints designed for each respective seat.
●Adjust the head restraints to the correct position at all times.
●Do not drive with the head restraints removed.
■The active head restraint on the front passenger seat
Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which may prevents the sensor from
detecting the passenger’s weight properly . As a result, the active head restraint
may not activate in the event of an accident.
■Active head restraint precautions
●Do not put head restraint covers.
●For removal, installation, modification, disassembly or disposal of the active head
restraints, contact your Lexus dealer.
Inappropriate handling of th e active head restraints may prevent them from oper-
ating properly during an accident.

LS600hL_U(OM50E41U)
■To prevent sensor error
To ensure that the sensors operate properly,
do not touch or cover them.
CAUTION
Do not adjust the position of the mirror while driving.
Doing so may lead to mishandling of the vehicle and cause an accident, resulting in
death or serious injury.

2364-3. Operating the lights and wipers
LS600hL_U(OM50E41U)
■Daytime running light system
●To make your vehicle more visible to other drivers, the parking lights turn on auto-
matically (at an increased intensity) whenever the hybrid system is started and the
parking brake is released. Daytime running lights are not designed for use at night.
●Compared to turning on the headlights, the daytime running light system offers
greater durability and consumes less electricity, so it can help improve fuel econ-
omy.
■Headlight control sensor
■Automatic light off system
●When the headlights are on: The headlights and tail lights turn off 30 seconds after
a door is opened and closed if the power switch is turned to ACCESSORY mode
or turned off. (The lights turn off immediat ely if on the key is pressed after all the
doors are closed.)
●When only the tail lights are on: The tail lights turn off automatically if the power
switch is turned to ACCESSORY mode or turned off and the driver’s door is
opened.
To turn the lights on again, turn the power switch to ON mode, or turn the light
switch off once and then back to or .
If any of the doors or trunk lid is kept op en, the lights automatically turn off after 20
minutes.
■Light reminder buzzer
A buzzer sounds when the power switch is turned off or turned to ACCESSORY
mode and the driver’s door is opened while the lights are turned on.
■Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number of pas-
sengers and the loading conditio n of the vehicle to ensure that the headlights do not
interfere with other road users. The sensor may not func tion properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
