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 CD player and CDs

Your CD player is intended for use with 12 cm (4.7 in.) CDs
only.
 Extremely high temperature can keep your CD player from
working. On hot days, use air conditioning to cool the
vehicle interior before you listen to a CD.
 Bumpy roads or other vibrations may make your CD player
skip.
 If moisture gets into your CD player, you may not hear any
sound even though your CD player appears to be working.
Eject all CDs from the player and wait until the player dries.
CAUTION
CD players use an invisible laser beam which could
cause hazardous radiation exposure if directed outside
the unit. Be sure to operate the player correctly.

Correct Wrong
 Handle CDs carefully, especially when you set them into the
player. Hold them on the edge and do not bend them. A void
getting fingerprints on them, particularly on the shiny side.
 Dirt, scratches, warping, pin holes, or other CD damage
could cause the player to skip or to repeat a section of a
track. (To see a pin hole, hold the CD up to the light.)
20L039
To clean a CD: 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 CD (not in a circle). Do not use a
conventional record cleaner or anti −static device.

STARTING AND DRIVING

31L346a
When you enter the vehicle carrying a sm art key and push
the ignition switch, the electronic code in the key is
automatically checked as to whether it corresponds to the
registered ID code for the vehicle. The key indicator light
comes on, the steering column lock is released, and the
engine immobilizer system is cancelled.
At this time, the security indicator light goes off and you can
start the engine when you turn the ignition switch and the key
indicator light does not come on. When you turn the ignition
switch, turn it slowly and surely. If you turn it quickly, it may
become stuck. To free it, see the following “If the ignition switch
seems to be stuck”.
If you push the ignition switch when the smart key is not within
the effective range of the smart key system, a warning tone
sounds and “Key is not Detected” appears on the display. If the ignition switch seems to be stuck:
To free the ignition switch, perform the following:
31L638
1. Push the ignition switch.

31L321a
 1“P” (Park) position 2“N” (Neutral) position
1. Start the engine as instructed in “How to start the
engine” on page 304.
The transmission must be in “P” or “N” position. The engine wi\
ll
not start in any drive position even if the ignition switch is turned
to “START”.
31L322
 1 Power position 2Normal position
3Snow position
2. Set the driving pattern selector switch to the “Normal”
position.
Your transmission has a driving pattern selector switch which
allows you to select “Power”, “Normal” or “Snow” mode to suit\
your driving condition. For ordinary driving, Lexus
recommends that you use the “Normal” position to improve fuel
economy.
3. For more powerful acceleration and sporty driving, use
the “Power” position.
In the “Power” position, the “ECT PWR” light in the instrument
cluster is on and the transmission is shifted up at higher vehicle
speeds and shifted down more responsively than in the
“Normal” position.
For “Snow” mode, see “Electronic Throttle Control
System” on page 315.

STARTING AND DRIVING
316In the power mode, the “ECT PWR” light in the instrument
cluster is on and the transmission is shifted up at higher vehicle
speeds and shifted down more responsively
than in the normal
mode.
To return to the normal mode, push the driving pattern selector
switch lightly on the “SNOW” side.
Snow mode: For slippery road surfaces such as in snow. In
this mode, the spinning of the rear wheels is controlled
appropriately.
When you push the driving pattern selector switch on the
“SNOW” side, the snow mode is turned on and the “ECT
SNOW” light in the instrument cluster comes on.
To return to the normal mode, push the driving pattern selector
switch on the “SNOW” side again.
When you turn the ignition switch off in the snow mode, the
mode automatically changes to the normal mode.
LEXUS PARK ASSIST SYSTEM
31L354b
 Sensors
The Lexus park assist system will help you to easily park
by detecting any obstacle around your vehicle with
ultrasonic sensors and informing you of the approximate
distance from the vehicle to the obstacle with the
indicators on the display and with beeping sounds.*
This system will operate at a vehicle speed of less than about
10 km/h (6 mph) with the selector lever in a position other than
“P”.
NOTE:
* The volume of the beeps can be changed.
Ask your Lexus dealer for details.

STARTING AND DRIVING
321
CAUTION
Do not install an accessory or the like within the sensor
detection range. Doing so may cause the Lexus park
assist system to malfunction, resulting in an accident.
NOTICE
The sensors do not detect an obstacle just under the
bumper. A short object, thin stake or the like will be
detected once but might not be detected as your
vehicle gets very close to such an object.
 If an obstacle is very close to your vehicle, it might
not be detected.
 If a sensor is subjected to a strong impact, it will not
operate properly.
The Lexus park assist system may not work properly in
the following cases:
When icicles, snowflakes or mud gets on the sensors.
If removed, the system will work properly.
 When the sensor is frozen.
If deiced, the system will work properly.
 When the sensor is covered with something.
If removed, the system will work properly. Especially in cold weather, a malfunction warning screen may
appear on
the display due to frozen sensors. If the “Clean Park
Sonar” appears on the display, be sure to clean the sensor. If
the “Clean Park Sonar” appears despite no mud, ice or
snowflakes on the sensor, the sensor might have
malfunctioned. Have your vehicle checked by your Lexus
dealer.
In the following conditions, the detection range may be
affected:
 When you stop your vehicle in extreme hot or cold weather.
 Foreign matter such as snowflakes or mud gets on the
sensor.

STARTING AND DRIVING
345
CAUTION
Deceleration cruising function and approach
warning do not operate when the vehicle ahead is at
a stop or driving very slowly
 While vehicletovehicle distance control (followup
cruising) is on, acceleration and deceleration are
automatically performed in proportion to the speed
of the vehicle ahead detected. However, if the vehicle
ahead of you decelerates abruptly or if another
vehicle cuts in ahead of you, your vehicle may collide
with the vehicle ahead unless you manually depress
the brake pedal to slow down your vehicle. If you
need to accelerate because the vehicle ahead or you
changes lanes, then depress the acceleration pedal.
 Depending on the road configuration (curved roads,
left and right continuous curved roads, driving at the
start or end of the curve, narrow driving lanes due to
road construction) or your vehicle condition
(steering wheel maneuvering, position in the lane or
unstable driving because of an accident or
breakdown), vehicles in other lanes or surrounding
objects will be detected, resulting in a control failure
or the activated approach warning. This may also
result in a very close distance between vehicles due
to a failure to detect the vehicle ahead. Maneuvering
the steering wheel in response to a violent lateral
wind will cause similar conditions.
31L588
CAUTION
If other vehicles are driving outside of the millimeter
wave radar or laser radar detection range, a delay in the
detection of the vehicle cutting in at short range or
detection failure of the motorcycle running on the side
of the same lane will occur. In this case, the dynamic
radar/laser cruise control system will not function
properly.

STARTING AND DRIVING
350
CAUTION
To ensure that the dynamic radar cruise control system
will function properly while driving, observe the
following:
Always keep the millimeter wave radar sensor and
grille cover clean. When cleaning, use a soft cloth
and be careful not to damage the sensor and grille
cover.
 Avoid strong impacts around the millimeter wave
radar sensor. An incorrect millimeter wave radar
sensor alignment will result in system malfunction.
A special device is required to adjust the millimeter
wave radar sensor alignment. Be sure to have the
sensor adjusted by your Lexus dealer.
 Do not disassemble the millimeter wave radar
sensor.
 Do not affix a sticker (including a transparent sticker)
or attach an accessory around the millimeter radar
sensor or the grille cover.
 Do not modify or paint the grille cover. When
replacing the cover, be sure to use a genuine cover.

ELECTRONICALLY MODULATEDAIR SUSPENSION
This electronically modulated air suspension adjusts the
damping effect on the shock absorbers and the vehicle
height. This adjustment is automatically made in
response to the driving conditions to provide good riding
comfort and stability in all driving conditions.
(a) Vehicle height adjustment
31L343
 1High position 2Normal position
This system maintains a stable vehicle height, regardless
of occupants and luggage weight. Select either of the
following modes using a selector switch. Normal mode:
Suitable for driving on roads with a normal
surface.
High mode: Suitable for driving on rough roads which are
unsurfaced or continually bumpy.
The damping effect is set slightly firmer in the high mode. So
you may feel the vibration of the vehicle compared to in the
normal mode. However, this does not mean a malfunction in
the system. We recommend you use a normal mode in normal
driving.
To change the mode, push the selector switch.
Normal mode:
The vehicle height remains at normal height at all driving
speeds.
High mode:
The vehicle height switches between the following two vehicle
heights according to the driving conditions:
Vehicle height
Driving condition
NormalMedium and high speed driving
HighLow speed driving

STARTING AND DRIVING

Antilock 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 antilock
brake system, your vehicle may require a longer
stopping distance in the following cases:
Driving on rough, gravel or snowcovered 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 antilock brake system detects vehicle
speeds u sing the speed 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.“ABS” warning light
31L350
 1 U.S.A. 2Canada
The light comes on when the ignition switch is turned to the
“ON” position. If the anti−lock brake system and the brake
assist system work properly, the light turns off after a few
seconds. Thereafter, if either of the systems malfunctions, the
light comes on again.
When the “ABS” warning light is on (and the brake system
warning light is off), the anti −lock brake system, the brake
assist system, the traction control system and/or the vehicle
stability control system do/does not operate, but the brake
system still operates conventionally.
When the “ABS” warning light is on (and the brake system
warning light is off), the anti− lock brake system does not
operate so that the wheels could lock up during a sudden
braking or braking on slippery road surfaces.
