In the following cases, the master warning light flashes, a
warning tone sounds and the above message appears.
 An electronic key is not detected in the vehicle when you
push the engine switch. In this case, the above message
appears for 8 seconds.
 An electronic key is not detected in the vehicle because
someone has taken an electronic key outside of the vehicle
without turning the engine switch off. At this time, the
electronic key sounds an alarm. The above message turns
off if you turn the engine switch off or the entry function
detects an electronic key in the vehicle.
In addition to either of the above conditions, if you get out from
the vehicle, having an electronic key when the engine switch
is selected in “IG −ON” mode and the selector lever is in a
position other than “P”, “SHIFT TO P RANGE” and “KEY IS
NOT DETECTED” appear alternately.

If you get out from the vehicle, having an electronic key
when the engine switch is selected in “IGON” mode and
the selector lever is in a position other than “P”, the
master warning light flashes, a beep sounds inside the
vehicle and the above message appears. When you shift
the selector lever to the “P” position or start driving, the
beeping stops sounding, the above message turns off.
In addition to the above condition, if the entry function does not
detect an electronic key in the vehicle, “SHIFT TO P RANGE”
and “KEY IS NOT DETECTED” appear alternately.

If the entry function determines that the battery voltage is
low (2V to 3V) when the engine switch is turned off more
than 20 minutes after turned on, the master warning light
flashes, a warning tone sounds and the above message
appears.
If the above message appears, the battery needs to be
replaced. Although you can replace the battery referring to
“Replacing the battery ” on page 34 , we recommend you have
it replaced by your Lexus dealer as it is easy to be scratched.

To avoid serious personal injury, you must do the
following.
 While the vehicle is moving, always keep the heads,
hands and o ther parts of the bodies of all occupants
away from the roof opening. Otherwise, they could
be seriously injured if the vehicle stops suddenly or
if the vehicle is involved in an accident.
 Before you close the moon roof, always make sure
there is nobody around the moon roof. You must also
make sure nobody places his or her head, hands and
other parts of the body in the roof opening. If
someone’s neck, head or hands get caught in the
closing roof, it could result in death or serious injury.
When anyone closes the moon roof, first make sure
it is safe to do so.
 Be sure to turn the engine switch to “OFF” mode
when you leave your vehicle.
 Never leave anyone (particularly a small child) alone
in your vehicle, especially when the engine switch is
on. Otherwise, he/she could use the moon roof
switches and get trapped in the roof opening.
Unattended persons (particularly a small child) can
be involved in a serious accident.
 Never sit on top of the vehicle around the roof
opening.
