2005 LEXUS LS430 section 5

STARTING AND DRIVING
335
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
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 grille cover of your vehicle, and if detected, a
message is shown on the multiinformation 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
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
grille cover clean.

STARTING AND DRIVING
337
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 vehicletovehicle 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
multiinformation 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 vehicletovehicle 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.

Precaution for precollision safety system
It should be noted that the pre−collision sensor may detect the
following as the objects with which your vehicle might collide,
and the pre −collision safety may operate, even though there
is no possibility of collision.
 When traveling through a curve, there is an object on the
edge of the road.
 When traveling through a curve, another vehicle is passing
from the opposite direction.
 When traveling across a narrow iron bridge.
 When there is a metallic object on the road.
 When there is a steel plate on the road at a construction site.
 When there is a bump on the road.
 When waiting to turn to the left in an intersection, and
another vehicle is passing from the opposite direction.
 If your vehicle approaches another vehicle ahead very
quickly.CAUTION
Do not rely solely on the precollision safety system
to avoid accidents. Your safe and attentive driving
practices are still the best way to avoid accidents and
you are always responsible for the operation of the
vehicle and the safety of your passengers. When
driving, always pay attention to the surrounding
conditions and the course you are driving.
 The precollision sensor’s collision detection
performance is limited. The sensor is able to detect
a forward object within 10 degrees on either left or
right side. If it is out of the range, or if there is no or
weak millimeter wave reflection, the sensor could not
detect the object and the system does not work
properly.
 Even if the precollision safety is operative in an
unavoidable collision, unless the seat belts are worn
and the brake pedal is depressed, the precollision
seat belts and precollision brake assist system will
not work.

on your vehicle.
You can be confident that your Lexus dealer’s service
department performs the best job to meet the maintenance
requirements of your vehicle − reliably and economically.
Your copy of the repair order is proof that all required
maintenance has been performed for warranty coverage. If
any problems should arise with your vehicle while under
warranty, your Lexus dealer will promptly take care of it. Again,
be sure to keep a copy of the repair order for any service
performed on your Lexus.
What about doityourself maintenance?
Many of the maintenance items are easy to do yourself, if you
have a little mechanical ability and a few basic automotive
tools. Simple instructions for how to perform them are
presented in Section 6.
If you are a skilled do −it− yourself mechanic, the Lexus service
manuals are recommended. Please be aware that
do− it−yourself maintenance can affect your warranty
coverage. See “Owner’s Guide”, “Owner’s Manual
Supplement” or “Warranty Booklet” for the details.
GENERAL MAINTENANCE

Lexus dealer or qualified service shop for their advice.
CAUTION
Make these checks only with adequate ventilation if you
run the engine.
Engine compartment
Items listed below should be checked from time to time,
e.g. each time when refueling.
Washer fluid
Make sure there is suf ficient fluid in the tank. See page 503 for
additional information.
Engine coolant level
Make sure the coolant level is between the Upper and Lower
lines on the see−through reservoir when the engine is cold.
See page 455 for additional information.
Radiator, condenser and hoses
