ENGINE IMMOBILIZER SYSTEM
Deactivation using the smart key system
11L222a
The engine immobilizer system is a theft prevention
system. When you enter the vehicle carrying a smart key
and push the ignition switch, the electronic code in the
key is automatically checked to determine whether it
corresponds to the registered ID code for the vehicle. If
the key indicator light comes on after the ID code
verification, you can start the engine.
This system is automatically set when the ignition switch is
turned to the “LOCK” position. At this time, the security
indicator light flashes. When you push the ignition switch, the
security indicator light goes out and the system is cancelled
automatically, which enables the engine to start.
The engine immobilizer system cannot be cancelled if the
cancel switch of the smart key system is turned on. For details,
see “Deactivating the smart key system” on page 34.

The operational range of the wireless remote control is
approximately 1 m (3 ft.). The effective range may vary with
different conditions. To activate the wireless remote control
without fail, do it approximately 1 m (3 ft.) from your Lexus.
In the following cases, th
e battery in the key may be

For the replacement of the battery of the Type B key, see
“Replacing the battery” on page 44. You can also have the
battery of the key replaced by your Lexus dealer.
If you lose the wireless function key, contact your Lexus dealer
as soon as possible to avoid the possibility of theft, or an
accident. (See “If you lose your keys or lock yourself out” on
page 424.)
If your vehicle is equipped with smart key system, you can use
up to 5 master keys and 3 valet keys for the same vehicle. In
case of the vehicle not equipped with smart key system, up to
4 master keys are available. Contact your Lexus dealer for
detailed information. The wireless remote control function key is an electronic
component. Observe the following instructions in order
not to cause damage to the key.

Do not leave the wireless remote control function key in
places where the temperature becomes high such as on the
dashboard.
 Do not disassemble it.
 Avoid knocking it hard against other objects or dropping it.
 Avoid putting it in water.

OCCUPANT RESTRAINT SYSTEMS
184Deployment of the
airbags happens in a fraction of a second,
so the airbags must inflate with considerable force. While the
system is designed to reduce serious injuries, primarily to the
head and chest, it may also cause other, less severe injuries
to the face, chest, arms and hands. These are usually in the
nature of minor burns or abrasions and swelling, but the force
of a deploying airbag can cause more serious injuries,
especially if an occupant’s hands, arms, chest or head is in
close proximity to the airbag module at the time of deployment.
This is why it is important for the occupant to; avoid placing any
object or part of the body between the occupant and the airbag
module; sit straight and well back into the seat; wear the
available seat belt properly; and sit as far as possible from the
airbag module, while still maintaining control of the vehicle.
Parts of the airbag module (steering wheel hub, lower portion
of instrument panel, airbag cover and inflator) may be hot for
several minutes after deployment, so do not touch! The
airbags inflate only once. The windshield may be damaged by
absorbing some of the force of the inflating airbag.
CAUTION
The driver or front passenger who is too close to the
steering wheel, lower portion of instrument panel or
dashboard during airbag deployment can be killed or
seriously injured. Lexus strongly recommends that:
 The driver sit as far back as possible from the
steering wheel while still maintaining control of the
vehicle.
 The front passenger sit as far back as possible from
the dashboard.
 All vehicle occupants be properly restrained using
the available seat belts.
 If the seat belt extender has been connected to the
driver’s seat belt buckle but the seat belt extender
has not also been fastened to the latch plate of the
driver’s seat belt, the SRS driver’s airbag system will
judge that the driver is wearing the seat belt even
though the seat belt has not been connected. In this
case, the driver’s airbag may not activate correctly,
causing death or serious injury in the event of a colli-
sion. Be sure to wear the seat belt with the seat belt
extender. Otherwise, there will also not be any effec-
tive protection in a sudden stop or a collision pro-
vided by the seat belt.
For instructions and precautions concerning the
seating position, see “Front seat precautions” on page
154.

OCCUPANT RESTRAINT SYSTEMS
185
16L637
Do not sit on the edge of the seat or lean against the
dashboard when the vehicle is in use, since the front
passenger airbag could inflate with considerable
speed and force. Anyone who is up against, or very
close to, an airbag when it inflates, can be killed or
seriously injured. Sit up straight and well back in the
seat, and always use your seat belt properly.
16L638
 Lexus strongly recommends that all infants and
children be placed in the rear seat of the vehicle and
be properly restrained.
 Do not allow a child to stand up or kneel on the front
passenger seat, since the front passenger airbag
could inflate with considerable speed and force.
Otherwise, the child may be killed or seriously
injured.
 Do not hold a child on your lap or in your arms. Use
a child restraint system in the rear seat. For
instructions concerning the installation of a child
restraint system, see “Child restraint” on page 199.

OCCUPANT RESTRAINT SYSTEMS
186
16L794
Do not put anything or any part of your body on or in
front of the dashboard, lower portion of instrument
panel, steering wheel pad that houses the front
airbag system or in the areas where the SRS knee
airbags will inflate. They might restrict inflation or
cause death or serious injury as they are projected
rearward by the force of the deploying airbags.
Likewise, the driver and front passenger should not
hold objects in their arms or on their knees.
 If a vinyl cover is put on the area where the SRS knee
airbag will deploy, be sure to remove it.
Do not attach any objects except Lexus genuine
parts in the area where the SRS knee airbag for the
front passenger will inflate. When using an ashtray
or auxiliary box on the front passenger’s console
box, be sure to keep it closed. The attached object, or
opened ashtray or auxiliary box might restrict
inflation of the airbag or be thrown away by the force
of the deploying airbag, causing a danger.
 Do not modify or remove any wiring. Do not modify,
remove, strike or open any components, such as the
steering wheel pad, steering wheel, column cover,
dashboard near the front passenger airbag, front
passenger airbag cover, front passenger airbag,
knee airbags or airbag sensor assembly. Doing so
may prevent the front airbag system from activating
correctly, cause sudden activation of the system or
disable the system, which could result in death or
serious injury.
Failure to follow these instructions can result in death
or serious injury. Consult your Lexus dealer about any
repair and modification.

OCCUPANT RESTRAINT SYSTEMS
187
16L759
Do not attach any heavy, sharp or hard objects such
as keys or accessories to the ignition key. The
objects may restrict the SRS knee airbag inflation or
be thrust into the driver’s seat area by the force of the
deploying airbag, causing a danger.
NOTICE
Do not perform any of the following changes without
consulting your Lexus dealer. Such changes can
interfere with proper operation of the SRS front airbag
system in some cases.
 Installation of electronic devices such as a mobile
twoway radio, cassette tape player or CD player.
 Modification of the suspension system.
 Modification of the front end structure.
 Attachment of a grille guard (bull bar, kangaroo bar,
etc.), snowplow, winches or any other equipment to
the front end.
 Repairs made on or near the front fenders, front end
structure, console, steering column, steering wheel,
lower portion of instrument panel or dashboard near
the front passenger airbag.

AIR CONDITIONING
252
(d) Operating tips
Make sure the air inlet grilles in front of the windshield are
not blocked by leaves or other obstructions.
 If air flow control is not satisfactory, check the dashboard
vents. (See “Center vents”, “Side vents” and “Rear vents”.)\
 To help cool down the interior after parking in the hot sun,
drive for the first few minutes with the windows open. After
the excess heat has blown away, close the windows.
 When driving on dusty roads, close all windows. If dust
thrown up by the vehicle is still drawn into the vehicle after
closing the windows, it is recommended that the air intake
control button be left to the OUTSIDE AIR mode and the fan
speed control button be pressed to anywhere except the
“OFF” button.
 If following another vehicle on a dusty road, or driving in
windy and dusty conditions, it is recommended that the air
intake control button be temporarily pressed in to the
RECIRCULATED AIR mode, which will close off the outside
passage and prevent outside air and dust from entering the
vehicle interior.
Center vents
21L064a
The center vents may be opened or closed as shown.
21L057b
Push the swing button to swing the vanes.
The vanes directly aimed at the driver and front passenger will
swing wider as the room temperature nears the desired
temperature. The swinging angle will also change from narrow
to wide depending on the room temperature.
