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, which prevents the sensor from detecting the pas-
senger’s weight properly. As a result, the seat belt pretensioner for the front passen-
ger’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 shoulder.
The belt should be kept away from your ne ck, 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 3 )■
Seat belt damage and wear ●
Do not damage the seat belts by allowing th e 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’s 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 handling
may lead to incorrect operation. ■
Using a seat belt extender ●
Do not wear the seat belt extender if you can fasten the seat belt without the extender. ●
Do not use the seat belt extender when in stalling a child restraint system because the
belt will not securely hold the child restraint system, increasing the risk of death or
serious injury in the event of an accident. ●
The personalized extender may not be safe on another vehicle, when used by another
person, or at a different seating position other than the one originally intended.

RX450h_U_OM0E013U Your vehicle is equipped with ADVANCED AIRBAGS designed based on the
US motor vehicle safety standards (FMVSS208). The airbag sensor assembly
(ECU) controls airbag deployment based on information obtained from the sen-
sors etc. shown in the system compon ents 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 moti on of the occupants.SRS airbag system components

SRS airbag precautions ●
If breathing becomes difficult after the SRS airbags have deployed, open a door or
window to allow fresh air in, or leave the vehicl e if it is safe to do so. Wash off any resi-
due 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, which prevents the sensor from detecting the pas-
senger’s weight properly. As a result, th e SRS front airbags for the front passenger
may not deploy in the event of a collision. ■

consulting your Lexus dealer. The SRS airb ags may malfunction or deploy (inflate)

RX450h_U_OM0E013U The air intake/discharge vents for the
hybrid battery (traction battery) are
located under the rear seats and in lug-
gage compartment respectively. If the
air intake vents are blocked, it could
lead to a reduction in hybrid battery
(traction battery) output.
When a certain level of impact is detected by the impact sensor, the emergency
shut off system blocks the high voltage current and stops the fuel pump to mini-
mize the risk of electrocution and fuel leakage. If the emergency shut off system
activates, your vehicle 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
