CAUTION
Do not adjust the mirror while the vehicle is moving.
Doing so may cause the driver to mishandle the vehicle
and an accident may occur resulting in death or serious
injuries.
To ensure correct functioning of anti glare mirror sensors
located on both sides of the mirror, do not touch or cover
the sensors with your finger or a piece of cloth, etc.

The vehicle is in a place where the earth’s magnetic field is
subject to interference by artificial magnetic fields
(underground parking, under a steel tower, between
buildings, roof parking, near a crossing, near a large vehicle,
etc.).
The vehicle is magnetized. (There is a magnet or a metal
object on or near the inside rear view mirror.)
The battery has been disconnected.
If your vehicle is out of the set zone, refer to “Calibrating the
compass” in this Section to set the zone number.
If the deviation is small, the compass works to calibrate the
direction automatically while the vehicle is in motion.
For obtaining additional precision or for complete calibrating,
see “Calibrating the compass” below.
If the direction is not indicated or the system does not operate
properly, contact your Lexus dealer.

NOTICE
Do not put magnets or a metal object on or near the
inside rear view mirror of the vehicle. Doing this may
cause malfunction of the compass sensor in the mirror.

Close the power outlet lid when the power outlet is
not in use. Inserting anything other than an
appropriate plug that fits the outlet may cause
electrical failure or short circuit.
The power outlet is not designed for the following electric
appliances even though their power consumption is
under 115 VAC/100W. These appliances may not operate
properly.
Appliances with high initial peak wattage: Cathode −ray
tube type televisions, compressor −driven refrigerators,
electric pumps, electric tools, etc.
Measuring devices which process precise data: Medical
equipment, measuring instruments, etc.
Other appliances requiring an extremely stable power
supply: Microcomputer −controlled electric blankets, touch
sensor lamps, etc.
Certain electrical appliances may cause radio noise.
Headphone jacks
You can enjoy the rear seat entertainment system with
commercial headphones.
To use the headphones, connect them to the jack.
The key must be in the “ACC” or “ON” position.

Vehicle to vehicle distance control mode
The system’s laser radar sensor detects the reflectors of
vehicles and measures the vehicle to vehicle distance.
The detection range of the sensor is about 120 m (400 ft.)
ahead.
CAUTION
Dynamic laser cruise control is not a
collision avoidance system and will not prevent
accidents. Dynamic laser cruise control is a vehicle
speed control device that is intended for use only on
freeways or roads where the traffic is light or moderate.
To avoid serious injury, you must use caution and be
attentive to road and traffic conditions while using
dynamic laser cruise control.

STARTING AND DRIVING

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.
