Event data recorder
Your vehicle has computers that monitor and control certain
aspects of your vehicle. These computers assist in driving and
maintaining optimal vehicle performance. Besides storing
data useful for troubleshooting, there is a system to record data
in a crash or a near car crash event. This is called an Event
Data Recorder (EDR).
The SRS airbag sensor assembly contains the EDR. In a
crash or a near car crash event, this device may record some
or all of the following information:

Engine speed

Whether the brake pedal was applied or not

Vehicle speed

To what extent the accelerator pedal was depressed

Position of the transmission selector lever

Whether the driver and front passenger wore the seat belts
or not

Driver's seat position

Front passenger's occupant classification

SRS airbag deployment data

SRS airbag system diagnostic data If your vehicle is equipped with a vehicle stability control (VSC)
system,
its Electronic Control Unit (ECU) may contain another
EDR. There are a variety of driving situations which include
activating the VSC under which the VSC EDR will record
certain information. The VSC EDR may record some or all of
the following information:

Behavior of the vehicle

Steering wheel angle

Vehicle speed

To what extent the accelerator pedal was depressed

To what extent the brake pedal was applied

To what extent the ECU controlled the condition of the 4
wheels

Vehicle stability control system diagnostic data
The information above is intended to be used for the purpose
of improving vehicle safety performance. Unlike general data
recorders, the EDR does not record sound data such as
conversation between passengers.

Tires and loading on your Lexus
Underinflated or overinflated tire pressure and the
excess load may result in the deterioration of steering
ability and braking ability, leading to an accident.
Check the tire inflation pressure periodically and be
sure to keep the load limits given in this Owner's
Manual. For details about tire inflation pressure and
load limits, see pages 574 and 483.
Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your
Lexus contain explosive chemicals. If the vehicle is scrapped
with the airbags and seat belt pretensioners left as they are,
this may cause an accident such as a fire. Be sure to have the
systems of the SRS airbag and seat belt pretensioner removed
and disposed of by a qualified service shop or by your Lexus
dealer before you scrap your vehicle.
On±pavement and off±road driving tips
This vehicle belongs to the utility vehicle class. Utility vehicles
have a significantly higher rollover rate than other types of
vehicles. This vehicle will handle and maneuver differently
from an ordinary passenger car because it is designed for
off±road use also. In addition, this vehicle has a higher ground
clearance and center of gravity than that of an ordinary
passenger car. This vehicle design feature causes this type of
vehicle to be more likely to rollover. Failure to operate this
vehicle correctly may result in loss of control, accidents or
vehicle rollover causing death or serious injury. Be sure to read
ªOff±road vehicle precautionsº on page 459 and ªOff±road
driving precautionsº on page 464.
Leak detection pump
This pump performs fuel evaporation leakage check. This
check is done approximately five hours after the engine is
turned off. So you may hear sound coming from underneath
the luggage compartment for several minutes. It does not
indicate a malfunction.

SEATS
While the vehicle is being driven, all vehicle occupants should
have the seatback upright, sit well back in the seat and properly
wear the seat belts provided.
CAUTION
 Do not drive the vehicle unless the occupants are
properly seated. Do not allow any passengers to sit
in the luggage compartment or cargo area. Persons
not properly seated and/or not properly restrained by
seat belts can be severely injured in the event of
emergency braking or a collision.
 During driving, do not allow any passengers to stand
up or move around between seats. Otherwise, severe
injuries can occur in the event of emergency braking
or a collision.
FRONT SEATS
Front seat precautions
Driver seat
CAUTION
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. The National Highway
Traffic Safety Administration (ªNHTSAº) advises:
Since the risk zone for driver airbag is the first 50 Ð 75
mm (2 Ð 3 in.) of inflation, placing yourself 250 mm (10
in.) from your driver airbag provides 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.

OCCUPANT RESTRAINT SYSTEMS
126
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 by
NHTSA above, while still maintaining control of the foot
pedals, steering wheel, and your view of the instrument
panel controls.
Front passenger seat
CAUTION
The SRS front passenger airbag also deploys with
considerable force, and can cause death or serious
injury especially if the front passenger is very close to
the airbag. The front passenger seat should be as far
from the airbag as possible with the seatback adjusted,
so the front passenger sits upright.
Front seats (with SRS side airbags)
CAUTION
The SRS side airbags are installed in the driver and front
passenger seats. Observe the following precautions.
 Do not lean against the front door when the vehicle
is in use, since the side airbag inflates with
considerable speed and force. Otherwise, you may
be killed or seriously injured.
 Do not use seat accessories which cover the area
where the side airbags inflate. Such accessories may
prevent the side airbags from activating correctly,
causing death or serious injury.
 Do not modify or replace the seats or upholstery of
the seats equipped with side airbags. Such changes
may prevent the side airbag system from activating
correctly, disable the system or cause the side
airbags to inflate accidentally, resulting in death or
serious injury.

OCCUPANT RESTRAINT SYSTEMS
171
Deployment 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 are 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, 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 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.
For instructions and precautions concerning the
seating position, see ªFront seat precautionsº on page
125.

OCCUPANT RESTRAINT SYSTEMS
174
Do not put anything or any part of your body on or in
front of the dashboard or steering wheel pad that
houses the front airbag system. 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.
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,
front passenger airbag cover, front passenger airbag
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.
If you wish to modify your vehicle for a person with a
physical disability, consult your Lexus dealer. It may
dangerously interfere with the SRS front airbags
operation.
