STARTING AND DRIVING

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
vehicletovehicle 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.
 On the roads in heavy traffic or at sharp bends:
As an appropriate speed cannot be maintained,
serious injury or death could result.
 On slippery road surfaces (icy or snowcovered 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 serious injury or death. (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 warning tone sounds frequently (because
acceleration or deceleration was repeated or
sufficient vehicletovehicle distance was not
maintained), an appropriate vehicle speed cannot be
attained, resulting in serious injury or death.
 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 serious injury or death.

STARTING AND DRIVING
342In the following case, the preset speed automatically
cancels out. At this time, the multiinformation 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.
Dynamic radar cruise control—
e. The wipers are operated at high speed (including high
speed operation with the wiper lever in the “AUTO” position.)
Dynamic laser cruise control—
f. The wipers are operated at high or low speeds (including
high and low speed operations with the wiper lever in the
“AUTO” position.)

If the system cannot easily measure the
vehicletovehicle distance because of the following
conditions while the dynamic radar/laser cruise control is
on, the above message appears.
Dynamic radar cruise control—
 The driving pattern selector switch is set to the “SNOW”
mode.
 It is determined that it is difficult to make a measurement
because of bad weather (such as extremely hot weather)
 The wipers are operated at high speed with the wiper lever
in the “AUTO” position
Dynamic laser cruise control—
 The driving pattern selector switch is set to the “SNOW”
mode.
 It is determined that it is difficult to make a measurement
because of bad weather (such as rainy, foggy, or snowy
weather)
 The wipers are operated at high or low speeds with the
wiper lever in the “AUTO” position.
 Direct sunlight from the front In the following
cases, the dynamic radar/laser cruise
control switches to the “RADAR READY” mode:
Dynamic radar cruise control—
 The driving pattern selector switch is changed to the
“normal” or “power” position.
 The wipers are stopped or are switched to low speed or
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.

If the system malfunction is detected when dynamic
radar/laser cruise control is in the “RADAR READY” mode
or operating, the above message appears.
If this message appears, stop your vehicle in a safe place, turn
the ignition off, and then restart it to reset the system. If the
setting still cannot be made or the same message appears
again, the system might have malfunctioned. Although it is no
problem to continue driving, contact your Lexus dealer.
NOTICE
While you are cruising with the dynamic radar/laser
cruise control on, if the master warning light comes on,
the cruise indicator light flashes, “Check Cruise
System” appears on the multiinformation display and
the warning tone sounds, turn the ignition switch off
and then on again. If the function is cancelled again
after setting or if settings cannot be made, the dynamic
radar/laser cruise control system may be
malfunctioning. Although it is no problem to continue
driving, have your vehicle checked by your Lexus
dealer.
