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.

The moon roof may not operate automatically and the jam
protection function will not function correctly after you

Make sure the moon roof opens and closes automatically. If
the moon roof cannot be operated properly, have it checked by
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.

IF YOUR ENGINE STALLS WHILEDRIVING
If your engine stalls while driving . . .
1. Reduce your speed gradually, keeping a straight line. Move
cautiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Turn the engine switch off, and try starting the engine again.
If the engine will not start, see ”If your vehicle will not start”\
.
CAUTION
If the engine is not running, the power assist for the
brakes and steering will not work, so steering and
braking will be much harder than usual.
IF YOUR VEHICLE WILL NOT START
(a) Simple checks
Before making these checks, make sure you have followed the
correct starting procedure instructions in ”Operating the
engine switch” on page 342 and that you have sufficient fuel.
Since your vehicle is equipped with the engine immobilizer,
also check whether the other keys will start the engine. If they
work, your electronic key may be broken. Have the key
checked at your Lexus dealer. If none of your keys work, there
may be a malfunction in the engine immobilizer. Call your
Lexus dealer. See ”Keys” on page 8.
If the engine is not turning over or is turning over too
slowly
1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is cranked,
the battery is discharged. You may try jump starting. See ”(c)
Jump starting” for further instruction.
If the light is O.K., but the engine still will not start, it needs
adjustment or repair. Call a Lexus dealer, Roadside
Assistance or Customer Service Assistance. (See
”Foreword”.)
