Folding rear view mirrors
16L018
To fold the rear view mirror, push backward.
The rear view mirrors can be folded backward for parking in
restricted areas.
CAUTION
Do not drive with the mirrors folded backward. Both the
driver and passenger side rear view mirrors must be extended
and properly adjusted before driving.
INSIDE REAR VIEW MIRROR
16L019-1
Pushing the switch changes the mode between ”AUTO” and
”DAY”.
The indicator comes on when the ”AUTO” mode is selected.
”DAY” mode: The mirror surface is normal.
”AUTO” mode: If the mirror detects light from the headlights
of the vehicle behind you, the mirror surface darkens slightly to
reduce the reflected light.
When the inside rear view mirror surface changes, the outside rear
view mirror surfaces will also become darker.
When the ignition key is inserted and turned on, the inside rear view
mirror always turns on in the ”AUTO” mode.
Adjust it before driving so that the rear view is the best.
When the outside air temperature is low, it may take a little longer
for the mirror to darken in response to the detection of headlights.

SUPPLEMENTAL RESTRAINT
SYSTEM (SRS)
The Supplemental Restraint System (SRS) consists of driver and
front passenger airbags, side airbags and seat belt pretensioners.
The combination of these 3 systems is designed to provide
further protection for the driver and front passenger when
added to the primary protection provided by the seat belts.
16L1181
Driver and front passenger airbags, and seat belt pretensioners
Driver and front passenger airbags:
In response to a severe frontal impact, the driver and front
passenger airbags work together with the seat belts to help
preventing or reduce injury by inflating, in order to decrease the
likelihood of the driver’s or front passenger’s heads or chests
from directly hitting the steering wheel or dashboard.Seat belt pretensioners:
In response to a severe frontal impact, the seat belts are quickly
drawn back in by the retractors so that the belts snugly restrain
the driver and front passenger.
The front passenger airbag is activated even with no passenger in the
front seat.
The seat belt pretensioners are activated together with the driver and
front passenger airbags, even with no passenger in the front seat.
Be sure to wear your seat belt.
CAUTION
The driver or front passenger 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.

16L1732
Side airbags
Side airbags:
In response to a severe side impact, the side airbag for the driver
or front passenger works together with the seat belt to help
preventing or reducing injury by inflating, in order to decrease
the impact mainly on the driver or front passenger’s chest.
The side airbag on the passenger seat is activated even with no
passenger in the front seat.
Be sure to wear your seat belt.
CAUTION
SRS side airbags inflate with considerable force. To avoid
potential death or serious injury during inflation of a side
airbag, Lexus strongly recommends that the driver and front
passenger;
Wear their seat belt.
Remain properly seated with their back against the seat at
all times.
16L136-2
The indicator comes on when the ignition key is turned to the
”ACC” or ”ON” position. It goes off after about 6 seconds. This
means the SRS is operating properly.
The SRS warning light system monitors the airbag sensor
assemblies, inflators, seat belt pretensioners, warning light,
interconnecting wiring and power sources.

16L029
The driver and front passenger airbags and seat belt
pretensioners are designed to activate in response to a severe
frontal impact within the shaded area between the arrows in the
illustration.
There may be the case that the driver and passenger airbags and seat
belt pretensioners will not activate with such an impact in which the
occupant wearing the seat belt correctly would not get serious injury.
The driver and front passenger airbags and seat belt pretensioners
will work if the severity of the impact is above the designed threshold
level, comparable to an approximate 20 km/h (14 mph) collision
when impacting straight into a fixed barrier that does not move or
deform.
If the severity of the impact is below the above threshold level, the
driver and front passenger airbags and seat belt pretensioners may
not work.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 it is involved in an underride
collision (e.g. a collision in which the nose of the vehicle
”underrides”, or goes under, the bed of a truck).
It is possible with collision severity at the marginal level of driver
and passenger airbag sensor detection and activation that only one
of your vehicle’s driver and front passenger airbags and seat belt
pretensioners will work.
For the safety of all occupants, be sure to always wear seat belts.

149 Radio reception
Usually, the problem with radio reception does not mean there is a
problem with your radio it is just the normal result of conditions
outside the vehicle.
For example, nearby buildings and terrain can interfere with FM
reception. Power lines or telephone wires can interfere with AM
signals. And of course, radio signals have a limited range, and the
farther you are from a station, the weaker its signal will be. In
addition, reception conditions change constantly as your vehicle
moves.
Here are some common reception problems that probably do not
indicate a problem with your radio:
FM
Fading and drifting stations Generally, the effective range of FM
is about 40 km (25 miles). Once outside this range, you may notice
fading and drifting, which increase with the distance from the radio
transmitter. They are often accompanied by distortion.
Multipath FM signals are reflective, making it possible for two
signals to reach your antenna at the same time. If this happens, the
signals will cancel each other out, causing a momentary flutter or
loss of reception.
Static and fluttering These occur when signals are blocked by
buildings, trees, or other large objects. Increasing the bass level may
reduce static and fluttering.Station swapping If the FM signal you are listening to is
interrupted or weakened, and there is another strong station nearby
on the FM band, your radio may tune in the second station until the
original signal can be picked up again.
AM
Fading AM broadcasts are reflected by the upper atmosphere
especially at night. These reflected signals can interfere with those
received directly from the radio station, causing the radio station to
sound alternately strong and weak.
Station interference When a reflected signal and a signal received
directly from a radio station are very nearly the same frequency, they
can interfere with each other, making it difficult to hear the
broadcast.
Static AM is easily affected by external sources of electrical noise,
such as high tension power lines, lightening, or electrical motors.
This results in static.
Caring for your cassette player and tapes
For high performance from your cassette player and tapes:
Clean the tape head and other parts regularly.
A dirty tape head or tape path can decrease sound quality and
tangle your cassette tapes. The easiest way to clean them is by
using a cleaning tape. (A wet type is recommended.)

AIR CONDITIONING AND AUDIO
150Use highquality cassettes:
Lowquality cassette tapes can cause many problems, including
poor sound, inconsistent playing speed, and constant
autoreversing. They can also get stuck or tangled in the cassette
player.
Do not use a cassette if it has been damaged or tangled or if its
label is peeling off.
Do not leave a cassette in the player if you are not listening to it,
especially if it is hot outside.
Store cassettes in their cases and out of direct sunlight.
Avoid using cassettes with a total playing time longer than 100
minutes (50 minutes per side). The tape used in these cassette is
thin and could get stuck or tangled in the cassette player.Caring for your compact disc player and discs
20L037
Use only compact discs labeled as shown. The player is intended
for use with 12 cm (4.7 in.) discs only.
Extremely high temperature can keep your compact disc player
from working. On hot days, use air conditioning to cool the
vehicle interior before you listen to a disc.
Bumpy roads or other vibrations may make your compact disc
player skip.
If moisture gets into your compact disc player, you may not hear
any sound even though your compact disc player appears to be
working. Remove the magazine from the player and wait until it
dries.

Correct
Wrong
Handle compact discs carefully, especially when you set them
into the magazine. Hold them on the edge and do not bend them.
Avoid getting fingerprints on them, particularly on the shiny side.
Dirt, scrapes, warping, pin holes, or other disc damage could
cause the player to skip or to repeat a section of a track. (To see
a pin hole, hold the disc up to the light.)
20L039
To clean a compact disc: Wipe it with a soft, lintfree cloth that has
been dampened with water. Wipe in a straight line from the center
to the edge of the disc (not in a circle). Do not use a conventional
record cleaner or antistatic device.
