Before driving
CAUTION
■Wearing a seat belt
Observe the following precautions to reduce the risk of injury in the event of sud-
den braking, sudden swerving or an accident.
Failing to do so may cause death or severe injury.
●Ensure that all passengers wear a seat belt.
●Always wear a seat belt properly.
●Each seat belt should be used by one person only. Do not use a seat belt for more
than one person at once, including children.
●Do not recline the seat any more than necessary to achieve a proper seating
position. The seat belt is most effective when the occupants are sitting up straight
and well back in the seats.
●Do not wear the shoulder belt under your arm.
●Always wear your seat belt low and snug across your hips.
■Seat belt pretensioners
●Do not place anything, such as a cushion, on the passenger’s seat. Doing so will
disperse the passenger’s weight, which pr events the sensor from detecting the
passenger’s weight properly. As a result, the seat belt pretensioner for the pas-
senger’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.

1-6. Theft deterrent system
Tilt sensorThe tilt sensor detects changes in vehicle inclination, such as when the
vehicle is towed away.
This system is designed to deter and p revent vehicle theft but does not
guarantee absolute security against all tilts.
The tilt sensor can be canceled using the cancel switch.
Canceling the tilt sensor
Remove the key from the ignition
switch and press the tilt sensor
cancel switch in the glove box.
To set the alarm with the tilt sensor
disabled, the alarm must be set
within 5 minutes after canceling
the sensor.
The tilt sensor will revert to on each
time the ignition switch is turned to
the “ON” position.
To cancel the tilt sensor, perform the necessary procedure each time
canceling the sensors is desired.

●The alarm will still be set even when the tilt sensor is canceled.
●After the tilt sensor is canceled, turning the ignition switch to the “ON” position
or unlocking the doors using the wireless remote control or key will re-enable
the tilt sensor.
●When the alarm system is set again, the intrusion sensor and tilt sensor will be
set.

Before driving
Airbag system componentsYour vehicle is equipped with AD VANCED AIRBAGS designed based
on US motor vehicle sa fety standards (FMVSS208). The airbag system
controls airbag deployment power for the driver and passenger. The
driver airbag system consist s of the driver’s seat position sensor etc. The
passenger’s airbag system consists of the passenger occupant classifica-
tion sensor etc. Passenger airbag

1-7. Safety information
The main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airb ag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and an airbag sensor.
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemica l reaction in the inflators quickly
fills the airbags with non-toxic gas to he lp restrain the motion of the occu-
pants.
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasion s may result from contact with a deploying (inflating)
SRS airbag.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel , airbag cover and inflator) as well as
the seats may be hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.
●For Safety Connect subscribers, if the SRS airbags deploy or in the event of a
severe rear-end collision, the system is designed to send an emergency call to
the response center, notifying them of the vehicle’s location (without needing to
push the “SOS” button) and an agent will attempt to speak with the occupants
to ascertain the level of emergency and assistance required. If the occupants
are unable to communicate, the agent automatically treats the call as an emer-
gency and helps to dispatch the necessary emergency services. ( P. 2 1 9 )

5-1. Essential information
Using a flatbed truckUse a flatbed truck suitable for vehicles with low ground clearance. To
prevent body damage, do not tow with a wheel-lift or sling type truck. We
recommend having your Lexus dealer or a commercial towing service
load and unload the vehicle whenever possible.
■ Before loading the vehicle on a flatbed truck
Deactivate the tilt sensor. ( P. 56)
■ After the vehicle is loaded
Select Neutral, apply the parking brake and turn the ignition
switch to the “LOCK” position.
Use wheel chocks for all 4 wheels to prevent the vehicle from rolling.
Secure the vehicle by strapping
the tires to the deck of the tow
truck as shown.
