Check surroundings for safety.
If a bright light (for example, sunlight reflected off the vehicle
body) is picked up by the camera, the smear effect* peculiar
to the camera may occur.
*: Smear effect — A phenomenon that occurs when a bright
light (for example, sunlight reflected off the vehicle body) is
picked up by the camera; when transmitted by the camera, the
light source appears to have a vertical streak above and below
it.
CRUISE CONTROL
The cruise control allows you to cruise the vehicle at a
desired speed over about 40 km/h (25 mph) with your foot
off the accelerator pedal.
Your cruising speed can be maintained although a slight speed
change may occur when driving up or down a gradient, within
the limits of engine performance. On steeper hills, a great
speed change will occur so it is better to drive without the cruise
control.
When the cruise control is on, the driving pattern of the
automatic transmission is fixed in the normal position,
regardless of the position of the selector switch.
CAUTION
To help maintain maximum control of your vehicle,
do not use the cruise control when driving in heavy
or varying traffic, or on slippery (rainy, icy or
snow covered) or winding roads.
Avoid vehicle speed increases when driving
downhill. If the vehicle speed is too fast in relation to
the cruise control set speed, cancel the cruise
control then downshift the transmission to use
engine braking to slow down.

Dynamic radar cruise control—
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
vehicle to vehicle 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 grille cover of your vehicle, and if detected, a
message is shown on the multi information display.
However, if the sensor or grille cover is covered with
a metallic vinyl bag, icicle, snowflakes, etc., dirt may
not be detected, resulting in improper
vehicle to vehicle 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
grille cover clean.

Dynamic radar cruise control should not be used in the
following conditions, to avoid death or serious injury.
In bad weather (such as rain, fog, snow , sandstorms,
or when raindrops or snowflakes get in the millimeter
wave radar sensor or the grille cover), the
vehicle to vehicle distance will not be measured
accurately.
If the wipers are operated at high speed (including the
high speed operation with the wiper lever in the
“AUTO” position), dynamic radar cruise control is
automatically cancelled. (In the case of the low speed
operation and intermittent wiper operation, it is not
cancelled.) Dynamic radar cruise control is
automatically cancelled when the measurement is
extremely unstable due to bad weather.
On the roads in heavy traffic or at sharp bends:
As an appropriate speed cannot be maintained, death
or serious injury could result.
On slippery road surfaces (icy or snow covered road
surfaces):
The tires will race and you will be unable to control.On steep downhill slopes:
If there is no vehicle detected ahead, the preset speed
will be easily exceeded because of inefficient engine
braking, resulting in death or serious injury. (In this
case, automatic braking will not work.) If there is a
vehicle detected ahead, the delay in deceleration
timing could cause death or serious injury.
When the warning tone sounds frequently (because
acceleration or deceleration was repeated or
sufficient vehicle to vehicle distance was not
maintained), an appropriate vehicle speed cannot be
attained, resulting in death or serious injury.
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,
resulting in death or serious injury.

Dynamic laser cruise control—
CAUTION
Certain conditions make vehicle detection difficult or
impossible.
As this system operates by detecting primarily the
reflectors of the vehicle ahead, the distance cannot
be accurately detected in the following cases,
resulting in improper vehicle to vehicle distance.
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.
Protective film is attached to the reflectors on the
vehicle ahead, or reflectors are not installed on the
vehicle ahead or are damaged.
Heavy luggage which is loaded in your trunk or on
top of your rear seats is raising up the nose of your
vehicle.
The laser radar sensor automatically detects dirt if it
is sticking to the sensor glass of your vehicle, and if
detected, a message is shown on the
multi information display. However, if the sensor
glass is covered with a transparent or translucent
vinyl bag, icicle, etc., dirt may not be detected,
resulting in improper vehicle to vehicle distance.
Continue driving with due care to the vehicle ahead.
If dirt is detected, the dynamic laser cruise control
function is automatically cancelled. Always keep the
sensor glass clean.

Dynamic laser cruise control should not be used in the
following conditions, to avoid serious injury or death.
In bad weather (such as rain, fog, snow, sandstorms
or direct sunlight, or when raindrops or snowflakes
get in the laser radar sensor glass), the
vehicle to vehicle distance will not be measured
accurately.
If the wipers are operated at high or low speeds
(including the high and low speed operation with the
wiper lever in the “AUTO” position), dynamic laser
cruise control is automatically cancelled. (In the case
of intermittent wiper operation, it is not cancelled.)
Dynamic laser cruise control is automatically
cancelled when the measurement is extremely
unstable due to bad weather.

342In the following case, the preset speed automatically
cancels out. At this time, the multi information display
shows “RADAR READY” and the dynamic radar/laser
cruise control enters the ready mode.
The vehicle speed falls below about 40 km/h (25 mph). (40
km/h (25 mph) is designated as a cancel speed.)
CAUTION
In this case, the warning tone reminds you that the
dynamic
radar/laser cruise control is cancelled and you
must apply the brakes to slow the vehicle.
In the following cases, the warning messages appear and
the preset speed automatically cancels out. When
dynamic radar/laser cruise control is restored, the
warning messages turn off and dynamic radar/laser
cruise control enters “RADAR READY” mode.
a. The slip indicator light blinks and a warning tone sounds.
(This occurs when the vehicle is about to skid.)
b. The driving pattern selector switch is set to “SNOW” mode.
c. The anti −lock brake system is activated by automatic
braking. (The warning tone sounds.)
d. The sensor does not operate properly because a foreign
matter sticks to the sensor.

intermittent operation. (Including intermittent and stopped
wipers in the “AUTO” position)
In the above conditions, press the control lever upward in the
“+ RES” direction and release it. The dynamic radar cruise
control will be restored, however, even after the weather
clears, if the setting operation cannot be performed or if the
warning message still appears, the system might have
malfunctioned. Although it is no problem to continue driving,
contact your Lexus dealer.

Conventional (fixed speed) cruise control
mode
This mode allows you to cruise at a desired speed over
about 45 km/h (28 mph) with your foot off the accelerator
pedal.
Cruising speed can be maintained, although a slight speed
change may occur when driving up or down a gradient, within
the limits of engine performance. On steeper hills, the speed
will change more radically so it is better to drive without cruise
control.
When cruise control is on, the driving pattern of the automatic
transmission is fixed in the normal position, regardless of the
position of the selector switch.
CAUTION
In the conventional (fixed speed) cruise control
mode, an approach warning does not activate even if
you are too close to the vehicle ahead, as neither the
presence of the vehicle ahead nor the
vehicle to vehicle distance is detected. Pay special
attention to the distance between your vehicle and
the vehicle ahead. Always confirm the setting in the
multi information display.
The conventional (fixed speed) cruise control mode
of the dynamic radar/laser cruise control should not
be used in the following conditions, which could
result in death or serious injury.
To help maintain maximum control of your vehicle,
do not use fixed speed control mode when using
dynamic radar/laser cruise control while driving in
heavy or varying traffic, or on slippery (rainy, icy
or snow covered) or winding roads.
Avoid vehicle speed increasing when driving
downhill. If the vehicle speed is too fast in relation
to the preset speed in the fixed speed control
mode, cancel the fixed control mode and then
downshift the transmission to use engine braking
to slow down.
