If the moon roof closes but then re-opens slightly
Stop the vehicle.
Press and hold the “CLOSE” switch until the moon roof com-
pletely closes.
During the operation, the moon roof will move in the manner out-
lined below. If the switch is released during the operation, the oper-
ation will have to be performed again from the beginning.
The moon roof will close, open and then pause for approximately
10 seconds. Then it will close, tilt up and pause for approximately 1
second, after which it will tilt down and open and then close.
If the moon roof does not fully close even after performing the above proce-
dure correctly, have the vehicle inspected by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
If the moon roof tilts down but then tilts back up
Stop the vehicle.
Press and hold the “TILT” switch until the moon roof moves into
the tilt up position and stops.
Release the “TILT” switch once and then press and hold the
“TILT” switch until the moon roof completely closes.
After moving to the tilt up position, the moon roof will move in the
following manner. If the switch is released during the operation, the
operation will have to be performed again from the beginning.
The moon roof will pause for approximately 10 seconds while in
the tilt up position and then make some fine adjustments. Follow-
ing this, it will pause for approximately 1 second, tilt down, open
and then close.
If the moon roof does not fully close even after performing the above proce-
dure correctly, have the vehicle inspected by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.

Engine immobilizer system
System maintenance
The vehicle has a maintenance-free type engine immobilizer system.
Conditions that may cause the system to malfunction
If the key is in contact with a metallic object
If the key is in close proximity to or touching a key to the security sys-
tem (key with a built-in transponder chip) of another vehicle
The vehicle's keys have built-in transponder chips that prevent the
engine from starting if the key has not been previously registered in
the vehicle's on-board computer.
Never leave the keys inside the vehicle when you leave the vehicle.
The indicator light flashes
after the “ENGINE START
STOP” switch has been
turned OFF to indicate that
the system is operating.
The indicator light stops
flashing after the “ENGINE

Canceling the intrusion sensor
The alarm will be set even when the intrusion sensor is canceled.
To re-enable the intrusion sensor, press the “ENGINE START STOP”
switch or unlock the doors using the wireless remote door lock function
while the intrusion sensor is canceled.
Automatic re-enabling of the intrusion sensor
When the alarm system is set again, the intrusion sensor will also be set.
Intrusion sensor
The sensor may trigger the alarm in the following situations. Before locking
the doors, turn off the intrusion sensor. (P. 103)
Persons or pets are in the vehicle.
Unstable items, such as dangling accessories or clothes hanging on the
coat hooks, are in the vehicle.
The windows or moon roof are open.
The vehicle is parked in a place where extreme vibration or noises occur,
such as in a parking garage.
The vehicle is inside an automatic or high-pressure car wash.
The vehicle experiences impacts, such as hail, lightning strikes, or other
kinds of repeated impacts or vibrations.
Ice or snow is removed from the vehicle, causing the vehicle to receive
repeated impacts or vibrations.
The wind or something similar causes an externally mounted reflectively
coated windshield cover to move.
When the battery is disconnected
Be sure to deactivate the alarm system.
If the battery is disconnected before deactivating the alarm system, the
alarm may be triggered when the battery is reconnected.
When using the mechanical key to unlock the doors or trunk
Deactivate the alarm.
If the doors or trunk are unlocked using the mechanical key with the alarm
operational, the alarm will be triggered.

Airbag system components
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly.
The airbag sensor assembly consists of a safing sensor and an air-
bag sensor.
In certain types of severe frontal or side impacts, the SRS airbag
system triggers the airbag inflators. A chemical reaction in the
inflators quickly fills the airbags with non-toxic gas to help restrain
the motion of the occupants. Knee airbags

If the SRS airbags deploy (inflate)
Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
A loud noise and white powder will be emitted.
Parts of the airbag module (steering wheel, airbag cover and inflator) as
well as the front seats, and parts of the front pillar, rear pillar and roof
side rail, may be hot for several minutes. The airbag itself may also be
hot.
The windshield may crack.
SRS airbag deployment conditions (front airbags)
The SRS front airbags will deploy in the event of an impact that exceeds
the set threshold level (the level of force corresponding to an approxi-
mately 20 - 30 km/h [12 - 18 mph] frontal collision with a fixed wall that
does not move or deform).
However, this threshold velocity will be considerably higher if the vehicle
strikes an object, such as a parked vehicle or sign pole, which can move or
deform on impact, or if the vehicle is involved in an underride collision
(e.g. a collision in which the front of the vehicle “underrides”, or goes
under, the bed of a truck, etc.).
It is possible that in some collisions where the forward deceleration of
the vehicle is very close to the designed threshold level, the SRS front
airbags and the seat belt pretensioners may not activate together.
SRS airbag deployment conditions (side and curtain shield airbags)
The SRS side airbags and SRS curtain shield airbags will deploy in the
event of an impact that exceeds the set threshold level (the level of force
corresponding to the impact force produced by an approximately 1500 kg
[3300 lb.] vehicle colliding with the vehicle cabin from a direction perpen-
dicular to the vehicle orientation at an approximate speed of 20 - 30
km/h
[12 - 18 mph]).

CAUTION
SRS airbag precautions
Observe the following precautions regarding the airbags.
Failure to do so may cause death or serious injury.
The driver and all passengers in the vehicle must wear their seat belts
properly.
The SRS airbags are supplemental devices to be used with the seat belts.
The SRS driver airbag deploys with considerable force, and can cause
death or serious injury especially if the driver is very close to the airbag.
Since the risk zone for driver airbag is the first 50 - 75 mm (2 - 3 in.) of
inflation, placing yourself 250 mm (10 in.) from your driver airbag pro-
vides you with a clear margin of safety. This distance is measured from
the center of the steering wheel to your breastbone. If you sit less than 250
mm (10 in.) away now, you can change your driving position in several
ways:
• Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 250 mm
(10 in.) distance, even with the driver seat all the way forward, simply
by reclining the back of the seat somewhat. If reclining the back of
your seat makes it hard to see the road, raise yourself by using a firm,
non-slippery cushion, or raise the seat if your vehicle has that feature.
• If your steering wheel is adjustable, tilt it downward. This points the
airbag toward your chest instead of your head and neck.
The seat should be adjusted as recommended above, while still maintain-
ing control of the foot pedals, steering wheel, and your view of the instru-
ment panel controls.
