REAR VIEW MONITOR SYSTEM
The rear view monitor system assists the driver by
displaying an image of the rear of the vehicle while
backing up. The displayed image on the screen is a
horizontally reversed mirror image of the inside rear
view
mirror.
To display the rear view image on the screen, place the
selector lever in the “R” position when the engine switch
is selected in “IGON” mode.
If you move the selector lever out of the “R” position, the screen
returns to the previous screen. Operating another function of
the navigation system will display another screen.
The rear view monitor system is a supplemental device
intended to assist back up. When backing up, be sure to check
behind and all around the vehicle visually.
Vehicles with intuitive parking assist—
When the intuitive parking assist is turned on and an obstacle
is detected in front or rear of your vehicle, a warning appears
on the right top of the rear view monitor. For details, see
“Intuitive parking assist” on page 365.

CAUTION
Never depend on the rear view monitor system
entirely when backing up. Always make sure your
intended path is clear.
Use caution just as you would when backing up any
vehicle.
 Never back up while looking only at the screen. The
image on the screen is different from actual
conditions. Depicted distances between objects and
flat surfaces will differ from actual distances. If you
back up while looking only at the screen, you may hit
a vehicle, a person or an object. When backing up, be
sure to check behind and all around the vehicle
visually and with mirrors before proceeding.
 Do not use the system when the trunk is not
completely closed.
 If the back of the vehicle is hit, the position and
mounting angle of the camera may change. Be sure
to have the camera’s position and mounting angle
checked at your Lexus dealer.
 If the temperature changes rapidly , such as when hot
water is poured on the vehicle in cold weather, the
system may not operate normally.
 If the camera lens becomes dirty, it cannot transmit
a clear image. If water droplets, snow, or mud adhere
to the lens, rinse with water and wipe with a soft cloth.
If the lens is extremely dirty, wash it with a mild
cleanser and rinse.
 Use your own eyes to assure rearward clearance, as
the displayed image may become faint or darker, and
moving images will be distorted or not entirely visible
when out side temperature is cold. When backing up,
be sure to check behind and all around the vehicle
visually and with mirror before proceeding.

DYNAMIC RADAR CRUISECONTROL
The vehicles with precollision system are equipped with
dynamic radar cruise control.
Dynamic radar cruise control allows you to drive at a
selected cruising speed over about 45 km/h (28 mph) with
your foot off the accelerator pedal, maintaining an
appropriate vehicletovehicle distance.
CAUTION
Do not rely excessively on dynamic radar cruise control
in order to avoid serious injury or death, or to prevent
accidents or to control the vehicle’s speed in
emergency situations. Do not use cruise control except
in appropriate road and traffic conditions. Always drive
carefully and attentively. Before using dynamic radar
cruise control, read and understand the following
instructions.

(a) Dynamic radar cruise control operations
G31012
The dynamic radar cruise control function operates
automatically and depending on whether a vehicle is
detected ahead
may change the speed of your vehicle as
follows: If no vehicle is running ahead of you:
1
Cruising at a fixed speed: If there is no vehicle detected
ahead, your cruising speed is maintained at the preset
speed from about 45 km/h (28 mph) to about 135 km/h (85
mph). The preset speed is displayed in the
multi−information display. For the vehicle speed setting,
see “Setting operation ” on page 402.
If a vehicle is detected ahead of you:
2 Deceleration cruising function: If a slower moving
vehicle is detected ahead of you, your vehicle cruising
speed decreases within the range of about 40 km/h (25
mph) to about 135 km/h (85 mph). The multi− information
display shows the preset speed, the detected vehicle
ahead and selected vehicle− to−vehicle distance. If your
vehicle gets closer to the vehicle ahead because of
insufficient automatic deceleration, then the warning tone
warns you to also manually apply brakes.
3 Followup cruising function: After deceleration, your
vehicle cruising speed changes in proportion to the speed
of the vehicle ahead to maintain an appropriate distance
from your vehicle to the vehicle ahead. The
vehicle −to−vehicle distance can be changed. For details,
see “Changing vehicle −to−vehicle distance setting” on
page 406.
4 Acceleration 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.

STARTING AND DRIVING
398
CAUTION
Under certain conditions where the vehicle in front
slows drastically, or is stopped, the dynamic radar
cruise control will neither warn you nor decelerate. The
driver must depress the brake pedal to slow down,
ensuring collision avoidance or that sufficient
vehicletovehicle distance is maintained.
When vehicle−to−vehicle distance control mode is activated,
you must still be attentive to road and traf fic conditions. Should
your vehicle speed decrease below about 40 km/h (25 mph),
the dynamic radar cruise control will shut off, requiring you to
apply the brakes to slow. When a vehicle ahead slows
suddenly, stops or a vehicle cuts in front, the system may slow
your vehicle abruptly, but the automatic braking will cease if the
speed decreases below about 40 km/h (25 mph) requiring the
driver’s manual application of brakes.
CAUTION
Certain conditions make vehicle detection difficult or
impossible.
 As this system operates by detecting primarily the
reflected wave from the rear end of the vehicle ahead,
the distance cannot be accurately detected in the
following cases, resulting in improper
vehicletovehicle distance.
♦ The rear section of the vehicle ahead is extremely
small such as an unloaded trailer.
♦ The vehicle ahead or other vehicles around you
are flinging up water or snow.
♦ Heavy luggage which is loaded in your trunk or on
top of your rear seats is raising up the nose of your
vehicle.
 The millimeter wave radar sensor automatically
detects dirt if it is sticking to the front of the sensor
or cover of your vehicle, and if detected, a message
appears on the multiinformation display. However,
if the sensor or cover is covered with a metallic vinyl
bag, icicle, snowflakes, etc., dirt may not be detected,
resulting in improper vehicletovehicle distance.
Continue driving with due care to the vehicle ahead.
If dirt is detected, the dynamic radar cruise control
function is automatically cancelled. Always keep the
sensor and cover clean.

(b) Turning the system on
G31011
To operate the dynamic radar cruise control, push the
“ON−
OFF” button. This turns the system on. When the
“CRUISE” indicator light in the instrument cluster comes on
and “RADAR READY” appears on the multi−information
display, you can now set your desired cruising speed and
vehicle −to−vehicle distance. Pushing the “ON −OFF” button
again will turn the system completely off and “CRUISE OFF”
will appear on the multi −information display.
When the engine switch is turned off, the system is also
automatically turned off. To use the dynamic radar cruise
control again, push the “ON −OFF” button again to turn it on.
When the engine switch is turned off, all the preset data is
cleared. When you use the dynamic radar cruise control again,
you need to reset the data. The multi−
information display will return to the
vehicle −to−vehicle distance screen about 6 seconds after the
vehicle− to−vehicle distance screen has been changed to
another screen.
CAUTION
To avoid accidentally engaging the cruise control, keep
the “ONOFF” button off when not using the dynamic
radar cruise control.

STARTING AND DRIVING
402(c) Setting operation
G31014

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. 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 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 message 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 410.
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 cruise control screen to
another screen even while the warning message is displayed.
