Before driving
CAUTION
nSRS airbag precautions
lDo 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 passenger's weight properly. As a result, the SRS front passenger airbag may
not deploy in the event of a collision.
nModification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications with-
out consulting your Lexus dealer.
The SRS airbags may malfunction or deploy (inflate) accidentally, causing death or
serious injury.
lInstallation, removal, disassembly and repair of the SRS airbags
lRepairs, modifications, removal or replacement of the steering wheel, instrument
panel, dashboard, seats or seat upholstery, front, side and rear pillars or roof side
rails
lRepairs or modifications of the front fender, front bumper, or side of the occupant
compartment

nDaytime running light system
lTo make your vehicle more visible to other drivers, the daytime running lights
turn on automatically whenever the engine is started and the parking brake is
released. Daytime running lights are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the switch.
lCompared to turning on the headlights, the daytime running light system offers
greater durability and consumes less electricity, so it can help improve fuel
economy.
nHeadlight control sensor
The sensor may not function 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.
