Near a TV tower, electric power plant, gas station, radio station, large
display, airport or other facility that generates strong radio waves or elec-
trical noise
When carrying a portable radio, cellular phone, cordless phone or other
wireless communication devices
When the electronic key is in contact with, or is covered by the follow-
ing 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
When multiple electronic keys are in the vicinity
When another wireless key (that emits radio waves) is being used nearby
When carrying or using the electronic key together with the following
devices that emit radio waves
• Another vehicle's electronic key or a wireless key that emits radio
waves
• Personal computer or personal digital assistant (PDA)
• Digital audio player
• Portable game system
If window tint with a metallic content or metallic objects are attached to

1-4. Opening and closing the windows and moon roof
IS250/220d/200d_EE
The moon roof can be operated when
The “ENGINE START STOP” switch is in IGNITION ON mode.
Moon roof open warning buzzer
The buzzer sounds and a message is shown on the multi-information display
in the instrument panel when the “ENGINE START STOP” switch is turned
OFF and the driver's door is opened with the moon roof open.
Door lock linked moon roof operation
The moon roof can be opened and closed using the mechanical key. (P.
516)
The moon roof can be closed using the entry function. (P. 3 8 )
Operating the moon roof after turning the “ENGINE START STOP” switch
OFF
The moon roof can be operated for approximately 45 seconds even after the
“ENGINE START STOP” switch is switched to ACCESSORY mode or
turned OFF. It cannot, however, be operated once either front door is
opened.
Jam protection function
If an object is detected between the moon roof and the frame while closing
or tilting down, travel is stopped and the moon roof opens slightly.
To reduce moon roof wind noise
When the moon roof is opened automatically, it will stop slightly before the
fully open position. Driving with the moon roof in this position can help
reduce wind noise.
Sunshade
The sunshade can be opened and closed manually. However, the sunshade
will open automatically when the moon roof is opened.
