290Radio reception
Usually, a 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. 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 ef fective 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 ne arly the same
frequency, they can interfere with each other, making it dif ficult
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 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.)

STARTING AND DRIVING
297

To ensure that the threeway catalytic converter and
the entire emission control system operate properly,
your vehicle must receive the periodic inspections
required by the Lexus Maintenance Schedule. For
scheduled maintenance information, refer to the
“Owner’s Manual Supplement / Scheduled
Maintenance”.
ENGINE EXHAUST CAUTION
CAUTION
Avoid inhaling the engine exhaust. It contains
carbon monoxide, which is a colorless and odorless
gas. It can cause unconsciousness or even death.
 Make sure the exhaust system has no holes or loose
connections. The system should be checked from
time to time. If you hit something, or notice a change
in the sound of the exhaust, have the system checked
immediately.
 Do not run the engine in a garage or enclosed area
except for the time needed to drive the vehicle in or
out. The exhaust gases cannot escape, making this
a particularly dangerous situation.
 Do not remain for a long time in a parked vehicle with
the engine running. If it is unavoidable, however, do
so only in an unconfined area and adjust the heating
or cooling system to force outside air into the vehicle.
Keep the trunk lid closed while driving. An open or
unsealed trunk lid may cause exhaust gases to be
drawn into the vehicle.
 To allow proper operation of your vehicle’s
ventilation system, keep the inlet grilles in front of the
windshield clear of snow, leaves, or other
obstructions.
 If you smell exhaust fumes in the vehicle, drive with
the windows open and the trunk lid closed. Have the
cause immediately located and corrected.

STARTING AND DRIVING
312Vehicles with the cruise control —
When
the cruise control is being used, even if you downshift
from “D” or “5” (fifth range) to “4” (fourth range)\
, engine
braking will not be enabled because the cruise control is not
cancelled. For vehicle speed reduction, see page 328.
Vehicles with the dynamic radar/laser cruise control —
When the cruise control is being used in the conventional
(fixed speed) cruise control mode or in the
vehicle −to−vehicle distance control mode, even if you
downshift from “D” or “5” (fifth range) to “4” (fourth range),
engine braking will not be enabled because the cruise
control is not cancelled. For vehicle speed reduction, see
pages 359 and 344.
 Shift into the “3” (third range) position. The transmission will
downshift to third gear when the vehicle speed is or
becomes lower than 146 km/h (91 mph) and more powerful
engine braking will be enabled.
If you drive in the “D” position: Shift the selector lever to
the “S” position and shift the lever down to the “–” posi\
tion
twice to select the “3” (third range). However, when you
move the lever to the “S” position while the AI shifting control
is operating, the first shift range will be “5” (fifth range), “\
4”
(fourth range) or “3” (third range) because the suitable shift
range is selected depending on the driving condition.
If you drive in the “S” position: Shift the selector lever
down to the “–” position to select “3” (third range). 
Shift into the “2” (second range) position. The transmission
will downshift to second gear when the vehicle speed is or
becomes lower than 98 km/h (61 mph) and more powerful
engine braking than that of the “3” (third range) position will
be enabled.
If you drive in the “D” position: Shift the selector lever to
the “S” position and shift the lever down to the “–” posi\
tion
three times to select “2” (second range).
If you drive in the “S” position: Shift the selector lever
down to the “–” position to select “2” (second range).
 Shift into the “1” (first range) position. The transmission will
downshift to first gear when the vehicle speed is or becomes
lower than 35 km/h (22 mph) and maximum engine braking
will be enabled.
If you drive in the “D” position: Shift the selector lever to
the “S” position and shift the lever down to the “–” posi\
tion
four times to select “1” (first range).
If you drive in the “S” position: Shift the selector lever
down to the “–” position to select “1” (first range).
CAUTION
Be careful when downshifting on a slippery surface.
The abrupt change in engine speed could cause the
vehicle to skid or spin.

Corner obstacles
Depending on the distance between your vehicle and the
obstacle, the display and beeps change as follows:
1 About 37.5 cm (1.1 ft.) to about 50 cm (1.5 ft.): 3 arcs
appear on the corner of the vehicle mark where the
obstacle is detected. At this time, the beeps remind you
that your vehicle is getting closer to the obstacle by
sounding intermittently.
2 About 25 cm (0.8 ft.) to about 37.5 cm (1.1 ft.): The
number of arcs will decrease from 3 to 2. The beeps
sound at shorter intervals than in step
1.
3 Less than about 25 cm (0.8 ft.): The number of arcs will
decrease from 2 to 1, and the bar blinks while the beeps
sound continuously.
Lexus park assist system failure warning
31L351
The system self check is automatically performed when
the Lexus park assist system is turned on. At this time if
an error is detected, the master warning light comes on
accompanied by 5 beeps, the faulty sensor blinks and
either of the following messages appear in the
multiinformation display.
 “Check Park Sonar”
 “Clean Park Sonar”
The sensors operate individually. When one sensor is
malfunctioning, you will notice sounding beeps and blinking
indicators to show that it is malfunctioning. If another sensor
detects an obstacle during this time, the approximate distance
to the obstacle will be shown by that sensor.

STARTING AND DRIVING
341
After bringing the vehicle to
the desired speed, press the
control lever downward in the “– SET” direction and release it.
This sets the vehicle at that speed. At this time, the
multi−information display indicates settings such as the preset
vehicle speed, whether a vehicle is present ahead and
selected vehicle −to−vehicle distance. If there is no vehicle
detected ahead, the dynamic radar/laser cruise control screen
does not display the vehicle ahead. At this time, you may take
your foot off the accelerator pedal. If you need to accelerate
− for example, when passing − depress the accelerator pedal
enough for the vehicle to exceed the preset speed. When you
release the accelerator pedal, the vehicle will return to the
control prior to acceleration.
You cannot set a desired speed if the master warning light
comes on, the warning tone sounds and the multi− information
display indicates a warning me ssage such as “Cruise not
Available”, “Clean Radar Sensor” or “Check Cruise System”.
If any of the above messages appears on the display, see
“Vehicle −to−vehicle distance control mode failure warning” on
page 352.
If you turn off the “ON−OFF” button while the warning message
is displayed, the warning message turns off and the
multi−information display switches to another screen. If no
warning message appears on the display, when you turn the
“ON−OFF” button on again, the setting can be made.
You can change the dynamic radar/laser cruise control screen
to another screen even while the warning message is
displayed.
2 Cancelling the preset speed
You can cancel the preset speed by doing any of the following:
a. Pulling the control lever toward you, in the ”CANCEL”
direction.
b. Depressing the brake pedal.
c. Pushing the “ON −OFF” button at the end of the cruise
control lever.
If cancelled by a. or b., the multi−information display shows
“RADAR READY” and the dynamic radar/laser cruise control
enters the ready mode.
If cancelled by c., the “CRUISE” indicator light goes off in the
instrument panel and the multi −information display shows
“CRUISE OFF”. In this case, the preset speed data is cleared,
and you must set the speed from the beginning.

STARTING AND DRIVING
346
CAUTION
When a slower vehicle in front of you leaves the lane,
the dynamic radar/laser cruise control will no longer
detect a vehicle ahead and will attempt to accelerate
the vehicle to the faster preset speed.
 When the vehicletovehicle distance control is on
(on followup cruising), your cruising speed is
regulated in proportion to the speed of the vehicle
ahead, so increasing the preset vehicle speed using
the control lever does not accelerate the vehicle.
However, if the vehicle ahead leaves the lane, your
cruising speed will increase up to the preset speed
because the preset speed has been set higher using
the control lever. Confirm the setting on the
multiinformation display.
(d) Changing vehicletovehicle distance
31L635
 1 Long 2Middle 3Short
You can select one of the following vehicletovehicle
distances: “Long”, “Middle” or “Short”. Each time you
push the “DISP2” switch briefly, the setting changes from
“Long” to “Middle” to “Short” and then back to “Long”.
You can confirm the setting on the multiinformation
display.
It should be noted that pushing the “DISP2” switch longer will
change to another screen.
Your vehicle speed changes in proportion to the speed of
the vehicle ahead, maintaining the selected distance.
However, if the vehicle speed is slower, the selected
distance will be shorter than the designated distance.
When the vehicle− to−vehicle distance control mode is
activated or the multi−information display indicates “RADAR
READY”, the vehicle −to −vehicle distance setting can be
changed.

STARTING AND DRIVING
347
The vehicle
−to− vehicle distance is always set to “Long” when
the ignition switch is turned on.
CAUTION
 Select the vehicletovehicle distance
considering traffic conditions. The approximate
vehicletovehicle distance based on time
interval when driving at 88 km/h (55 mph) is
shown below :
“Long” about 75 m (about 245 ft.) . . . . . . . .
“Middle” about 50 m (about 165 ft.) . . . . . .
“Short” about 30 m (about 100 ft.) . . . . . . .
If the vehicle speed is slower than 88 km/h (55 mph),
the distance will be shorter than the above.
 During long downhill driving, the vehicletovehicle
distance will be shorter than the selected distance.
(e) Braking control
Dynamic radar/laser cruise control is not a collision avoidance
system. If an approach warning is activated, depress the brake
pedal to decelerate to ensure an appropriate
vehicle −to−vehicle distance.
31L177
 1
Under the vehicletovehicle distance control
2Braking activated
Braking control is operating only when the vehicle −to− vehicle
distance control mode is selected and your vehicle speed
exceeds about 40 km/h (25 mph).
If you are getting closer to the vehicle ahead at relatively higher
speed than those of the vehicle ahead or if engine braking
cannot be applied properly, braking control is automatically
activated. The multi− information display changes as shown in
the illustration and the stop/tail lights on your vehicle and on the
vehicle on the display come on.

STARTING AND DRIVING
357
(b) Setting operation
31L637
Each function is described below.
1
Setting the desired speed
The transmission must be in “D”, “6” (sixth range), “5”\
(fifth
range) or “4” (fourth range) before you set the cruise control
speed in the conventional cruise control mode of the dynamic
radar/laser cruise control.
After bringing the vehicle to the desired speed, press the
control lever downward in the “– SET” direction and release it.
This sets the vehicle at that speed and the multi −information
display shows the preset speed. At this time, you may take
your foot off the accelerator pedal. If you need to accelerate
− for example, when passing − depress the accelerator pedal
enough for the vehicle to exceed the preset speed. When you
release the accelerator pedal, the vehicle will return to the
speed set prior to acceleration. You cannot set a desired speed if the master warning light
comes
on, the warning tone sounds and the multi− information
display indicates a warning message such as “Check Cruise
System”. If this messages appears on the display, see
“Conventional cruise control mode failure warning” on page
359.
If you turn off the “ON−OFF” button while the warning message
is displayed, the warning message turns off and the
multi−information display switches to another screen. When
you turn the “ON −OFF” button on again, the warning message
comes back on the display. If no warning message appears on
the display, the setting can be made.
You can change the dynamic radar/laser cruise control screen
to another screen even while the warning message is
displayed.
2 Cancelling the preset speed
You can cancel the preset speed by doing any of the following:
a. Pulling the control lever in the ”CANCEL” direction.
b. Depressing the brake pedal.
c. Pushing the “ON −OFF” button at the end of the cruise
control lever.
If cancelled by a. or b., the multi −information displays shows
nothing and the conventional cruise control enters the ready
mode.
If cancelled by c., the “CRUISE” indicator light goes off in the
instrument panel and the multi −information display shows
“CRUISE OFF”. In this case, the preset speed data is cleared,
and you must set the speed from the beginning.
