Jam protection function
If something gets caught into the roof opening during closing
operation, the moon roof stops and is open.
If the moon roof receives a strong impact, this function may
work even if nothing is caught.
If the battery is disconnected or run down
The moon roof may not operate automatically and the jam
protection function will not function correctly after you

your Lexus dealer.
CAUTION
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.

DRIVING POSITION MEMORYSYSTEM
A microcomputer will memorize the position of the driver’s
seat, and the positions of the tilt and telescopic steering, and
outside rear view mirrors. Three different driving position
profiles can be entered into the computer’s memory.
Recording a driving position in the computer’s memory can
only be done when the engine switch is selected in “IG −ON”
mode and the selector lever is in the ”P” position.
Setting the driving position
G16068
1. Adjust the driver’s seat, tilt and telescopic steering and
outside rear view mirrors to the desired position.
2. While pushing the ”SET” button, push button ”1”,”2” or
“3” until the signal beeps. The beep sound means that the positions are recorded in the
computer’s memory.
By repeating these two steps
and pressing the remaining
button, the driving position for another driver can be recorded.
To set a new memorized position, select the desired position
and perform step 2. The previous memory will be erased and
the new position will be set.
To make only slight changes to an already memorized position,
the easiest way is to first activate the memorized position, then
make the desired changes and perform step 2 above.
Recalling the memorized position
G16069
When you push button ”1”, ”2” or “3”, the driving position
will be automatically adjusted to the position recorded for
that button.
