ESP Lexus GX470 2004 Audio System / LEXUS 2004 GX470 FROM JAN. 2004 THROUGH JUL. 2004 PROD. (OM60A87U) Owner's Guide

AUDIO
362Here are some common reception problems that probably do
not indicate a problem with your radio:
FM
Fading
and drifting stations Ð 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.
Multi-path Ð 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 Ð These occur when signals are
blocked by buildings, trees, or other large objects. Increasing
the bass level may reduce static and fluttering.
Station swapping Ð 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 Ð AM broadcasts are reflected by the upper
atmosphere Ð 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 Ð 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 dif ficult
to hear the broadcast.
Static Ð 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 the best performance for 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.)
Use high-quality cassettes.
 Low-quality cassette tapes can cause many problems,
including poor sound, inconsistent playing speed, and
constant auto-reversing. 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
cassettes is thin and could get stuck or tangled in the
cassette player.
Caring for your compact disc player, DVD player and discs
 Your compact disc player and DVD player are intended for
use with 12 cm (4.7 in.) discs only.
 Extremely high temperatures can keep your compact disc
player and DVD player from working. On hot days, use the
air conditioning to cool the vehicle interior before you use
the players.
 Bumpy roads or other vibrations may make your compact
disc player and DVD player skip.
 If moisture gets into your compact disc player and DVD
player, the players may not play even though they appear
to be working. Remove the disc from the player and wait
until it dries.
CAUTION
Compact disc players and DVD players use an invisible
laser beam which could cause hazardous radiation
exposure if directed outside the unit. Be sure to operate
the players correctly.
Compact disc player
 Use only compact discs marked as shown above. The
following products may not be playable on your compact
disc player.
Copy-protected CD
CD-R (CD-Recordable)
CD-R W (CD-Re-writable)

Correct
Wrong
Handle compact discs carefully, especially when you are
inserting them. 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.)
 Remove discs from the compact disc player when you are
not listening to them. Store them in their plastic cases away
from moisture, heat, and direct sunlight.
To clean a compact disc: Wipe it with a soft, lint-free cloth
that has been dampened with water. Wipe in a straight line
from the center to the edge of the disc (not in circles). Dry it with
another soft, lint-free cloth. Do not use a conventional record
cleaner or anti-static device.

STARTING AND DRIVING
382
(c) Using the 3º, 2º and Lº positions
The 3º, 2º and Lº positions are used for strong engine braking
as described previously.
With the selector lever in 3º, 2º or Lº, you can start the vehicle
in motion as with the lever in Dº.
With the selector lever in 3º or 2º, the vehicle will start in f\
irst
gear and automatically shift to second gear.
With the selector lever in Lº, the transmission is engaged in
first gear.
NOTICE
Be careful not to over-rev the engine. Watch the tachometer to keep engine rpm from going into thered zone. The approximate maximum allowablespeed for each position is given below for yourreference:
Transmission Transfer Lº Hº
3º 53 km/h (33 mph) 136 km/h (85 mph) 2º 36 km/h (22 mph) 93 km/h (58 mph)Lº 21 km/h (13 mph) 54 km/h (33 mph)
Do not continue hill climbing or hard towing for a long time in the 3º, 2º or Lº position. This may causesevere automatic transmission damage from
overheating. To prevent such damage, 4º positionshould be used in hill climbing or hard towing.

CAUTION
Do not overestimate the anti-lock brake system:
Although the anti-lock brake system assists in
providing vehicle control, it is still important to drive
with all due care and maintain a moderate speed and
safe distance from the vehicle in front of you, because
there are limits to the vehicle stability and effectiveness
of steering wheel operation even with the anti-lock
brake system on.
If tire grip performance exceeds its capability, or if
hydroplaning occurs during high speed driving in the
rain, the anti-lock brake system does not provide
vehicle control.
Anti-lock brake system is not designed to shorten the
stopping distance: Always drive at a moderate speed
and maintain a safe distance from the vehicle in front of
you. Compared with vehicles without an anti-lock
brake system, your vehicle may require a longer
stopping distance in the following cases:
 Driving on rough, gravel or snow-covered roads.
 Driving with tire chains installed.
Driving over the steps such as the joints on the road.
 Driving on roads where the road surface is pitted or
has other differences in surface height.
Install all 4 tires of specified size at appropriate
pressure: The anti-lock brake system detects vehicle
speeds using the s peed sensors for respective wheels'
turning speeds. The use of tires other than specified
may fail to detect the accurate turning speed resulting
in a longer stopping distance.

OFF-ROAD DRIVINGPRECAUTIONS
When driving your vehicle off-road, please observe the
following precautions to ensure your driving enjoyment and to
help prevent the closure of areas to off-road vehicles.
a. Drive your vehicle only in areas where of f-road vehicles are
permitted to travel.
b. Respect private property. Get owner's permission before
entering private property.
c. Do not enter areas that are closed. Honor gates, barriers
and signs that restrict travel.
d. Stay on established roads. When conditions are wet,
driving techniques should be changed or travel delayed to
prevent damage to roads.
For owners in U.S. mainland, Hawaii and Puerto Rico:
To obtain additional information pertaining to driving your
vehicle off-road, consult the following organizations.
 State and Local Parks and Recreation Departments
 State Motor Vehicle Bureau
 Recreational Vehicle Clubs
 U.S. Forest Service and Bureau of Land Management
CAUTION
Always observe the following precautions to minimize
the risk of serious personal injury or damage to your
vehicle:
Drive carefully when off the road. Do not take
unnecessary risks by driving in dangerous places.
 Do not grip the steering wheel spokes when driving
off-road. A bad bump could jerk the wheel and injure
your hands. Keep both hands and especially your
thumbs on the outside of the rim.
 Always check your brakes for effectiveness
immediately after driving in sand, mud, water or
snow.
 After driving through tall grass, mud, rock, sand,
rivers, etc., check that there is no grass, bush, paper,
rags, stone, sand, etc. adhering or trapped on the
underbody. Clear off any such matter from the
underbody. If the vehicle is used with these materials
trapped or adhering to the underbody, a breakdown
or fire could occur.
 In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing
a seat belt. Therefore, the driver and all passengers
should fasten their seat belts whenever the vehicle is
moving.

DRIVING TIPS

Service connector for towing brake controller
Your vehicle is equipped with a service connector for the
towing brake controller as shown. Link the connector to the
towing brake controller via the sub wire harness stored in the
glove box. The detailed explanation of the sub wire harness
circuit is packed together with the sub wire harness. Be sure
to position the towing brake controller where it does not prevent
the driver from operating the pedal. Lexus recommends that
the sub wire harness be stored in the glove box when it is not
in use.
Tires
Ensure that your vehicle's tires are properly inflated. Adjust
the tire pressure to the recommended cold tire pressure
indicated below.
Tire pressure: 220 kPa (2.2 kgf/cm
2 or bar, 32 psi)
 The trailer tires should be inflated to the pressure
recommended by the trailer manufacturer in respect to the
total trailer weight.

DRIVING TIPS
4526. Make sure the hitch is disconnected. If not, raise the hitch
higher and repeat steps 2 through 5.
7. Move the vehicle forward in the LOº (low) mode where the
hitch does not touch anything in the Nº (normal) mode.
8. Put the rear height control air suspension in the Nº (normal)
mode.
Pre-towing safety check

Check that your vehicle remains level when a loaded or
unloaded trailer is hitched. Do not drive if the vehicle has an
abnormal nose-up or nose-down condition, and check for
improper tongue load, overload, worn suspension or other
possible causes.
 Make sure the trailer cargo is securely loaded so that it
cannot shift.
 Check that your rear view mirrors conform to any federal,
state/provincial or local regulations. If they do not, install
required rear view mirrors appropriate for towing purposes.
Trailer towing tips
When towing a trailer, your vehicle will handle differently
than when not towing. The three main causes of
vehicle-trailer accidents are driver error, excessive speed
and improper trailer loading. Keep these in mind when
towing:
 Before starting out, check the operation of the lights and all
vehicle-trailer connections. After driving a short distance,
stop and recheck the lights and connections. Practice
turning, stopping and backing with a trailer in an area away
from traffic until you learn the feel.
 Backing with a trailer is difficult and requires practice. Grip
the bottom of the steering wheel and move your hand to the
left to move the trailer to the left. Move your hand to the right
to move the trailer to the right. (This procedure is generally
opposite to that when backing without a trailer.) Also, just
turn the steering wheel a little at a time, avoiding sharp or
prolonged turning. Have someone guide you when backing
to reduce the risk of an accident.
 Because stopping distance may be increased,
vehicle-to-vehicle distance should be increased when
towing a trailer. For each 16 km/h (10 mph) of speed, allow
at least one vehicle and trailer length between you and the
vehicle ahead. Avoid sudden braking as you may skid,
resulting in jackknifing and loss of control. This is especially
true on wet or slippery surfaces.
