4Acceleration cruising function: If the vehicle ahead
changes lanes, your vehicle cruising speed will be
gradually increased up to the preset speed, and your
vehicle resumes fixed−speed cruising.
This system operates by detecting primarily the reflectors
of the vehicle ahead. The distance may not be accurately
or absolutely detected in the following cases:
The vehicle ahead has higher ground clearance, which
means that the placement of the reflectors is in a higher
position.
The rear section of the vehicle ahead is extremely dirty.
The vehicle ahead or other vehicles around you are
flinging up water or snow.
Excessive exhaust gas (black smoke) is coming from
the vehicle ahead or other vehicles around you,
obscuring your front view.
There is an obstruction (protective film, sticker , etc.) on
the reflectors on the vehicle ahead, or reflectors are not
installed on the vehicle ahead or are damaged.
Heavy luggage in the luggage compartment or rear
seats is causing the nose of your vehicle to tilt up.CAUTION
To avoid accidents, always keep the laser radar sensor
glass clean and never allow it to be covered with icicle
or any substance, so it can detect the vehicle in front.
(See “(k) Laser radar sensor” on page 430.)

CAUTION
Do not rely excessively on dynamic laser cruise control.
Observe the following precautions in order to avoid
serious injury or death:
Under certain conditions when the vehicle in front
slows abruptly, or is stopped, the dynamic laser
cruise control may be unable to decelerate
automatically or to warn you. You must apply the
brakes manually in order to maintain a safe
vehicle to vehicle distance or avoid collision.
Therefore, pay careful attention to following
distance, even when using the dynamic laser cruise
control.
Do not use dynamic laser cruise control in the
following conditions:
In bad weather (such as rain, fog, snow, sandstorms
or direct sunlight, or when raindrops or snowflakes
get on the laser radar sensor glass), the
vehicle to vehicle distance will not be measured
accurately.
When using the windshield wipers at high or low
speeds, the dynamic laser cruise control turns off.
On roads with heavy traffic or sharp bends, an
appropriate speed cannot be maintained and an
accident may occur.
On slippery road surfaces (icy or snow covered road
surfaces), the tires will race and you will be unable to
control the vehicle.
When there is no vehicle detected ahead on steep
downhill slopes, the preset speed will be easily
exceeded because of inefficient engine braking. (In
this case, automatic braking will not work.) If there is
a vehicle detected ahead, the delay in deceleration
timing could cause serious injury or death.
When the alarm sounds frequently (because of
frequent changes of speed or insufficient
vehicle to vehicle distance), this indicates that the
system cannot maintain an appropriate
vehicle to vehicle distance and an accident may
occur.
On roads with steep and short inclines and declines,
failure to detect the vehicle ahead will shorten the
distance between your vehicle and the vehicle ahead
and an accident may occur.

Deceleration cruising function and approach
warning do not operate when the vehicle ahead is at
a stop or driving very slowly.
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.
Depending on the road configuration (curved, left
and right continuous curved, the start or end of a
curve, or 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 may
be detected, resulting in a control failure or the
approach warning activation. This may also result in
a very close distance between vehicles due to a
failure to detect the vehicle ahead.
Dynamic laser cruise control should not be used in
circumstances which are inappropriate for any cruise control,
such as entering free way on− ramps or off−ramps.
CAUTION
Do not use dynamic laser cruise control when exiting
from or when entering or merging onto a freeway.
When you are following a slower moving vehicle and
exiting, the sensor does not detect the vehicle and
will accelerate to the preset speed.

430(k) Laser radar sensor
The laser radar sensor is used for vehicle to vehicle
distance control cruising.
If dirt is on the sensor glass, the dynamic laser cruise
control
function is automatically cancelled and a warning
code appears on the display. (See “(l) Vehicle to vehicle
distance control mode failure warning” on page 431.)
However, if the glass sensor is covered with ice or another
transparent substance, dirt may not be detected.
Before using the vehicle to vehicle distance control
mode, make sure the laser radar sensor glass is clean.
This product is a class I laser product complied with
21 C.F.R part 1040.10. and 1040. 11.
CAUTION
To ensure that dynamic laser cruise control will function
properly while driving, observe the following:
Always keep the laser radar sensor glass clean.
When cleaning, use a soft cloth and be careful not to
damage the sensor.
Avoid strong impacts around the laser radar sensor.
An incorrect laser radar sensor alignment will result
in system malfunction. A special device is required
to adjust the laser radar sensor alignment. Be sure
to have the sensor adjusted by your Lexus dealer.
Do not affix a sticker (including a transparent sticker)
or attach an accessory around the laser radar sensor.

(l) Vehicle to vehicle distance control mode failure
warning
1Warning code2 “CRUISE” indicator light
3Master warning light
If a system malfunction is detected when the
vehicle −to−vehicle distance control mode is on, the master
warning light comes on, a warning tone sounds and a warning
code appears on the display. Dynamic laser cruise control is
automatically cancelled.
If “E3” appears on the display, the “CRUISE” indicator light in
the instrument cluster also flashes. If “E1” appears on the display,
the system cannot easily
measure the vehicle −to−vehicle distance because of a dirty
laser radar sensor glass.
If this code appears, clean the sensor glass with a soft cloth
and try setting the preset speed again. If the dirt is removed
without cleaning, the system will automatically enter the ready
mode.
If the system does not enter the ready mode even after
cleaning or the code remains on the display, the system might
be malfunctioning. Although the vehicle may still be operated,
please contact your Lexus dealer.
CAUTION
Always keep the sensor glass clear and never allow it to
be covered with icicle or any substance, so it can detect
the vehicle in front.

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 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
1U.S.A.2Canada
The light comes on when the ignition key 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 the vehicle
stability control system do 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.
