4-5. Using the driving support systems
This mode employs a radar sensor to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, determines the current vehicle-to-vehicle following
distance, and operates to maintain a suitable following distance from the vehicle
ahead.
Note that vehicle-to-vehicle distance will clos e 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 switch.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears
When a vehicle is detected running ahead of you, the system automatically decelerates
your vehicle. When a greater reduction in ve hicle speed is necessary, the system applies
the brakes (the stop lights will come on at th is time). The system will respond to changes in
the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by
the driver. Approach warning warns you when the system cannot decelerate sufficiently to
prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehi cle will also stop (vehicle is stopped by sys-
tem control). After the vehicle ahead starts off, pressing the +/RES switch or depressing the
accelerator pedal will resume follow-up cruising.

4-6. Driving tips
Perform the following according to the
driving conditions:
 Do not try to forcibly open a window
or move a wiper that is frozen. Pour
warm water over the frozen area to
melt the ice. Wipe away the water
immediately to prevent it from
freezing.
 When the outside door handle is
frozen, unlock the doors using the
wireless remote control. If the out-
side door handles remain retracted
and do not move even if the doors
are unlocked using the wireless
remote control, pour warm water
over the frozen area to melt the ice
and wipe away the water immedi-
ately to prevent it from freezing. The
outside door handle may not retract
due to ice, however, the outside
door handle will return to the nor-
mal position after the ice melts.
 To ensure proper operation of the
climate control system fan, remove
any snow that has accumulated on
the air inlet vents in front of the
windshield.
 Check for and remove any excess
ice or snow that may have accumu-
lated on the exterior lights, vehicle’s
roof, chassis, around the tires or on
the brakes.
 Remove any snow or mud from the
bottom of your shoes before getting
in the vehicle.
■To protect windshield wipers
 P.198
Accelerate the vehicle slowly, keep a
safe distance between you and the
vehicle ahead, and drive at a reduced
speed suitable to road conditions.
Park the vehicle and shift the shift posi-
tion to P without setting the parking
brake. The parking brake may freeze
up, preventing it from being released. If
the vehicle is parked without setting
the parking brake, make sure to block
the wheels.
Failure to do so may be dangerous
because it may cause the vehicle to
move unexpectedly, possibly leading to
an accident.
NOTICE
■Repairing or replacing snow tires
Request repairs or re placement of snow
tires from any authorized Lexus retailer or Lexus authorized repairer, or any reli-able repairer.
This is because the removal and attach- ment of snow tires affects the operation
of the tire pressure warning valves and transmitters.

enabled.
 If the green indicator light flashes, an
emergency call is being made
(either automatically or manually).
 If no indicator lights illuminate, the
system is not enabled.
 If the red indicator light illuminates

years or more.
WARNING
■When the Emergency Call may not be made
●Any of the followings may occur. In such cases, report to the Public Safety
Answering Point (PSAP) by other means such as nearby public phones.
• It may sometimes be difficult to con- nect to the Public Safety Answering Point (PSAP) even in the reception
area of the cellular phone due to the reception level, or if the line is busy.In such cases, you may not be able to
connect to the Public Safety Answer- ing Point (PSAP) and thus will not be able to make emergency calls and
report to the emergency departments even though the system tries to con-nect to the Public Safety Answering
Point (PSAP).
• When the vehicle is out of the cellular
phone service area, the Emergency Call cannot be made.
• When any related equipment (such as the “SOS” button panel, indicator lights, microphone, speaker, DCM,
antenna, or any wires connecting the equipment.) has an abnormality, is damaged or broken, the Emergency
Call cannot be made.
• During the Emergency Call, the sys-
tem makes repeated attempts to con- nect to the Public Safety Answering Point (PSAP). However, if it cannot
connect to the Public Safety Answer- ing Point (PSAP) due to poor radio wave reception, the system may not be
able to connect to the cellular network and the call may finish without con-necting. The red indicator light will
blink for approximately 30 seconds to indicate this disconnection.
• This device may not function if a shock is applied to it.

6-1. Maintenance and care
WARNING
●If you directly touch the raindrop sen- sor body or if something bumps into the raindrop sensor
■Precautions regarding the exhaust
pipes and rear bumper diffusers
As exhaust gases cause the exhaust
pipes and rear bumper diffusers to become quite hot, do not touch the exhaust pipes and rear bumper diffusers
while the engine is running or immediately after the engine is turned off.
When washing the vehicle, be careful not to touch the exhaust pipes and rear
bumper diffusers until they have cooled sufficiently, as touching hot exhaust pipes and rear bumper diffusers can cause
burns.
■Precaution regarding the rear bumper with Blind Spot Monitor (if equipped)
If the paint of the rear bumper is chipped or scratched, the system may malfunc-
tion. If this occurs, consult any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
NOTICE
■Application of coatings to the vehicle body (vehicles with CFRP parts)
Do not apply any kind of coating to the vehicle body as doing so may damage
the paint or reduce its durability.
■To prevent paint deterioration and corrosion on the body and compo-
nents (aluminum wheels etc.)
●Wash the vehicle immediately in the
following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar, pollen or tree sap is present on the paint surface
• If dead insects, insect droppings or bird droppings are present on the paint surface
• After driving in an area contaminated with soot, oily smoke, mine dust, iron
powder or chemical substances
• If the vehicle becomes heavily soiled
with dust or mud
• If liquids such as benzene and gasoline
are spilled on the paint surface
●If the paint is chipped or scratched, have it repaired immediately.
●To prevent the wheels from corroding, remove any dirt and store in a place
with low humidity when storing the wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic substances or scrub with a hard brush.
This may damage the surfaces of the lights.
●Do not apply wax to the surfaces of the lights.
Wax may cause damage to the lenses.
■When using an automatic car wash
Set the wiper switch to the off position.
If the wiper switch is in AUTO, the wipers may operate and the wiper blades may be damaged.
