The windshield wipers and washer can be operated when
The “ENGINE START STOP” switch is in IGNITION ON mode.
Effects of vehicle speed on wiper operation
Vehicle speed affects the following even when the wipers are not in
“AUTO” mode.
Intermittent wiper interval
Wiper operation when the washer is being used (delay until drip preven-
tion wiper sweep occurs)
Low speed wiper operation selected, wiper operation will be switched from
low speed to intermittent wiper operation only when the vehicle is station-
ary.
(However, the mode cannot be switched when the adjustment dial for the
intermittent wiper interval is set to the lowest setting.)
Raindrop sensor (vehicles with rain-sensing windshield wipers)
If the wiper switch is turned to “AUTO” position while the “ENGINE
START STOP” switch is in IGNITION ON mode, the wiper will operate
once to show that auto mode is activated.
If the temperature of the raindrop sensor is 90C (194F) or higher, or -
30C (-22F) or lower, automatic operation may not occur. In this case,
operate the wipers in any mode other than “AUTO”.
Outside rear view mirror defogger activation linked to windshield wiper
operation
The outside rear view mirror defogger automatically turns on when you
operate the windshield wipers.
The sensor judges the amount of rain-
drops.

If no windshield washer fluid sprays
If there is washer fluid in the windshield washer fluid reservoir and no
washer fluid sprays, the nozzle may be blocked. In this case, contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional, and have your Lexus inspected.
Customization that can be configured at any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional
Settings (e.g. drip prevention function) can be changed.
(Customizable features P. 556)
CAUTION
Caution regarding the use of windshield wipers in “AUTO” mode (vehicles
with rain-sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in “AUTO” mode. Take care that your
fingers or anything else do not become caught in the windshield wipers.
Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windscreen and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
NOTICE
When the windshield is dry
Do not use the wipers, as they may damage the windshield.
When a nozzle becomes blocked
Do not try to clear it with a pin or other object. The nozzle will be damaged.
When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be caused if the lever is pulled
toward you and held continually.

Cruise control can be set when
The shift lever is in the D or range 4 or higher of S has been selected.
Range 4 or higher has been selected by using the paddle shift.
(vehicles with paddle shift switch)
Vehicle speed is above approximately 40 km/h (25 mph).
Accelerating after setting the vehicle speed
The vehicle can be accelerated normally. After acceleration, the set
speed resumes.
Even without canceling the cruise control, the set speed can be increased
by first accelerating the vehicle to the desired speed and then pushing the
lever down to set the new speed.
Automatic cruise control cancelation
Cruise control will stop maintaining the vehicle speed in any of the follow-
ing situations.
Actual vehicle speed falls more than approximately 16 km/h (10 mph)
below the preset vehicle speed.
At this time, the memorized set speed is not retained.
Actual vehicle speed is below approximately 40 km/h (25 mph).
VSC is activated.
If the cruise control indicator light flashes
Press the “ON-OFF” button once to deactivate the system, and then press
the button again to reactivate the system.
If the cruise control speed cannot be set or if the cruise control cancels

Driving in vehicle-to-vehicle distance control mode
This mode employs a radar sensor to detect the presence of vehi-
cles up to approximately 120 m (400 ft.) ahead, determines the cur-
rent vehicle-to-vehicle following distance, and operates to
maintain a suitable following distance from the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on
long downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-
to-vehicle distance can also be set by operating the vehicle-to-vehicle
distance control.
Example of deceleration cruising
When the vehicle ahead is driving slower than the set speed
When a vehicle is detected running ahead of you, the system automat-
ically decelerates your vehicle. When a greater reduction in vehicle
speed is necessary, the system applies the brakes. A warning tone
warns you when the system cannot decelerate sufficiently to prevent
your vehicle from closing in on the vehicle ahead.

208
2-4. Using other driving systems
IS250/220d/200d_EEExample of follow-up cruising
When following a vehicle driving slower than the set speed
The system continues follow-up cruising while adjusting for changes
in the speed of the vehicle ahead in order to maintain the vehicle-to-
vehicle distance set by the driver.
Example of acceleration
When there are no longer any vehicles ahead driving slower than
the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.
Approach warning
When your vehicle is too close to a vehicle ahead, and sufficient
automatic deceleration via the cruise control is not possible, the
display will flash and the buzzer will sound to alert the driver. An
example of this would be if another driver cuts in front of you
while you are following a vehicle. Apply the brakes to ensure an
appropriate vehicle-to-vehicle distance.
Warnings may not occur when
In the following instances, there is a possibility that the warn-
ings will not occur:
When the speed of the vehicle ahead matches or exceeds your
vehicle speed
When the vehicle ahead is traveling at an extremely slow
speed
Immediately after the cruise control speed was set
At the instant the accelerator is applied

Dynamic radar cruise control can be set when
The shift lever is in the D or range 4 or higher of S has been selected.
Range 4 or higher has been selected by using the paddle shift.
(vehicles with paddle shift switch)
Vehicle speed is above approximately 50 km/h (30 mph).
Accelerating after setting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed
resumes. However, during vehicle-to-vehicle distance control mode, the
vehicle speed may decrease below the set speed in order to maintain the dis-
tance to the vehicle ahead.
Automatic cancelation of vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the
following situations:
Actual vehicle speed falls below approximately 40 km/h (25 mph).
VSC is activated.
The sensor cannot operate correctly because it is covered in some way.
The windshield wipers are operating at high speed (when the wiper
switch is set to the “AUTO” mode or the high speed wiper operation
position).
When snow mode is set. (IS250 only)
If vehicle-to-vehicle distance control driving is automatically canceled for
any other reason, there may be a malfunction in the system. Contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional.

CAUTION
Before using dynamic radar cruise control
Do not overly rely on vehicle-to-vehicle distance control.
Be aware of the set speed. If automatic deceleration/acceleration is not
appropriate, adjust the vehicle speed, as well as the distance between your
vehicle and vehicles ahead by applying the brakes etc.
Cautions regarding the driving assist systems
Observe the following precautions.
Failure to do so may cause an accident resulting in death or serious injury.
Assisting the driver to measure following distance
The dynamic radar cruise control is only intended to help the driver in
determining the following distance between the driver’s own vehicle and
a designated vehicle traveling ahead. It is not a mechanism that allows
careless or inattentive driving, and it is not a system that can assist the
driver in low-visibility conditions. It is still necessary for driver to pay
close attention to the vehicle’s surroundings.
Assisting the driver to judge proper following distance
The dynamic radar cruise control determines whether the following dis-
tance between the driver’s own vehicle and a designated vehicle traveling
ahead is appropriate or not. It is not capable of making any other type of
judgement. Therefore, it is absolutely necessary for the driver to remain
vigilant and to determine whether or not there is a possibility of danger in
any given situation.
Assisting the driver to operate the vehicle
The dynamic radar cruise control has no capability to prevent or avoid a
collision with a vehicle traveling ahead. Therefore, if there is ever any
danger, the driver must take immediate and direct control of the vehicle
and act appropriately in order to ensure the safety of all involved.
To avoid inadvertent cruise control activation
Switch the cruise control off using the “ON-OFF” button when not in use.
