sensor detecting how bright the surroundings are. However, if the instrument panel
brightness has been manually set to either the brightest or darkest setting, the automatic
adjustment will not be performed.

WARNING
■Trunk easy closer (vehicles with power trunk opener and closer)
■Power trunk opener and closer (if equipped)
Observe the following precautions when operating the power trunk opener and closer.
Failure to do so may cause serious injury.
●Check the safety of the surrounding area to make sure there are no obstacles or any-
thing that could cause any of yo ur belongings to get caught.
●If anyone is in the vicinity, make sure they are safe and let them know that the trunk is
about to open or close.
●If the trunk closer switch is pressed while the trunk lid is opening during automatic
operation, the trunk lid stops opening. Take extra care when on an incline, as the trunk
lid may open or close suddenly.
●On an incline, the trunk lid may suddenly sh ut after it opens automatically. Make sure
the trunk lid is fully open and secure before using the trunk.
●In the following situations, the power trun k opener and closer may detect an abnor-
mality and automatic operation may be stoppe d. In this case, the trunk lid has to be
operated manually. Take extra care in this situation, as the stopped trunk lid may sud-
denly shut, causing an accident.
• When the trunk lid contacts an obstacle
• When the 12-volt battery voltage suddenly drops, such as when the power switch is turned to ON mode or the hybrid syst em is started during automatic operation
●Do not attach any accessories other than genuine Lexus parts to the trunk lid. The
power trunk opener and closer may not operate, causing itself to malfunction, or the
trunk lid may suddenly shut again after it is opened.
■Jam protection function (vehicles with power trunk opener and closer)
Observe the following precautions.
Failure to do so may cause serious injury.
●Never use any part of your body to intentionally activate the jam protection function.
●The jam protection function may not work if something gets caught just before the
trunk lid fully closes. Be careful not to catc h fingers or anything else in the trunk lid.
●The jam protection function may not work depending on the shape of the object that
is caught. Be careful not to catch fingers or anything else.
In the event that the trunk lid is left slightly open,
the trunk easy closer will automatically close it
to the fully closed position. It takes several sec-
onds before the trunk easy closer begins to
operate. Be careful not to catch fingers or any-
thing else in the trunk lid, as this may cause
bone fractures or other serious injuries.

■Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from receiving radio waves.
■Conditions affecting operation
The smart access system with push-button st art uses weak radio waves. In the following
situations, the communication between the electronic key and the vehicle may be
affected, preventing the smar t access system with push-but ton start, wireless remote
control and immobilizer system from operating properly. (Ways of coping: → P. 525)
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas st ation, radio station, large display, airport or
other facility that generates strong radio wave s or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wireless com-
munication device
●When the electronic key is in contact wi th, or is covered by the following metallic
objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
